The State of Cyber Warfare - Enterprise Security Management

Tuesday, December 1, 2009 by Pam Casale

Did you see the cyber warfare segment on CBS’s 60 Minutes? There’s an article, “Cyber War: Sabotaging the System” along with the video from the show, in case you missed it. CBS News correspondent Steve Kroft interviewed a host of people who are sure to know something about the country’s security – among them retired Admiral Michael McConnell and former State Department official Jim Lewis, who is currently director of the Center for Strategic and International Studies, about the current state of cyber warfare.

 

Jim Lewis tells Steve Kroft how a series of major successful espionage attacks were perpetrated in 2007 against the Departments of Defense, State, and Commerce and probably the Department of Energy and NASA, resulting in the theft of terabytes of sensitive data. Lewis also mentioned a case in December 2008 in which attackers entered highly-secured classified Department of Defense networks, using seemingly discarded thumb drives containing malware. I had nightmares after this segment. 

 

While the government can be expected to respond to these attacks by shoring up known holes and strengthening defenses, the basic question remains … “How come they didn’t detect the intruders immediately?” What we need to do, in both the public and private sectors, is to get much better at detecting anomalous behavior or even usual behavior that might have insidious elements.

We asked Warren Axelrod, a notable lecturer, practicioner and writer on information security how he would answer the question – “Warren, why didn’t they know?”

 

From the desk of Warren Axelrod: Pam, this news segment took my breath away as well. Let’s look at this for a moment. What we know is what security teams typically do is “close the barn door after the horse has fled”. As an example, we have seen how rogue USB devices can be used to infiltrate systems and networks. Consequently,we disable USB ports. Why wasn’t that done at the outset, since it is well known that viruses and malware are often resident on thumb drives? Unfortunately, sometimes we’re our own worst enemy.

When policies are created to disallow thumb drives, objections are often raised by powerful areas of influence – like the legal department. Their excuse is that they must respond immediately to requests for data. Similarly, the executive suite insists that they MIUST synchronize their whatever. Of course, after a breach, such arguments rapidly vaporize.

 

Nowyou might wonder why monitoring behavior on networks and systems include exceptions based on experiences after something bad has happened. Here’s a simple example: A criminal payables clerk accessed 400 hundred accounts per day when he/she was stealing information versus the usual twenty accounts per day. So someone gets the bright idea to report on anyone accessing more than 50 accounts per day. That makes sense if we’re just trying to avoid a recurrence of that type of breach.

But on closer inspection there are
two problems here: one is that those with evil intentions soon learn how to stay below the radar and adjust their activities accordingly and two, we typically check for previously-experienced events. What about events that haven’t been seen before – that is the unknown unknowns?


Check back here tomorrow to read Warren's recommendations! Have some recommendations of your own? Comment here!

Top 20 Security Controls - Protecting Information Assets

Monday, November 30, 2009 by Pam Casale
On November 13 SANS , the well known training and certification organization for security professionals, along with CSI has published version 2.3 of Top 20 Security Controls. This new version adds NIST SP 800-53 revision 3 mappings to the controls. It also adds an updated appendix to include in each area of direct mapping between 20 critical controls and the 800-53 Rev 3 Priority 1 controls. There's also a new appendix summarizing attack types that motivated the development of each control.

This is a terrific resource. SANS asked Intellitactics to provide definition of how a SIEM solution is used to automate monitoring and reporting of these controls. We were also asked to provide customer references who could verify that the Intellitactics SIEM solutions did in fact monitor and report on the controls. Intellitactics has initially provided extensive documentation on two of the controls and will submit context on other controls later in the month.

The US Comprehensive National Cybersecurity Initiative (CNCI) insists as a central tenet that knowledge of actual attacks that have compromised systems provide the essential foundation on which to construct effective defenses. The Federal Information Security Management Act in drafting US ICE Act of 2009 (often referred to as the new FISMA) includes the same mandate.

Government security executives agree that what is required is a jointly established priority baselines of information security measures and controls; and, they also agree that these controls be continuously monitored through automated mechanisms.

This is exactly what Intellitactics has been advising customers using our SIEM software and appliances - ISM and SAFE. We offer as part of these SIEM solutions a mapping of a superset of controls from ISO and NIST to regulatory standards like PCI, SOX, HIPAA and NERC. After all everyone has limits on how much they can spend and using a baseline of controls - like those offered in this important research can save a lot of time and money.

This week we'll take a closer look at two of the controls and explain how our SIEM solutions are used to monitor and report on the effectiveness of these controls. Check back to read more - in the meantime read about control monitoring using Intellitactics. 

Be Grateful for Enterprise Security Management Software

Wednesday, November 25, 2009 by Pam Casale
In kitchens across the United States, including mine, preparations are underway for cooking the traditional Thanksgiving dinner. In the security operations centers of retailers preparations are underway for Black Friday - the first day of what everyone hopes will be the beginning of a strong holiday spending season. And, for what everyone hopes will be a season of safe and secure online spending.

So let's take a moment to be grateful for enterprise security management software. Many of us may be able to recall - back in the day - when log collection was harder to do. There were never enough eyeballs for reviewing logs and never enough smart guys to understand what they were trying to say. Now, thanks to countless vendors and security professionals we've advanced the state of the technology: early detection of malicious activity, advanced analysis of source and targets that pinpoint abnormal activity. And, while we still can't prevent every attack, most of us know about it in time to do something about it. 

Enterprise security management software is something to be grateful for whether we're the cardholder or the card processor. Safe spending of what we have to spend is something we can all be grateful for.

Safe travels if you're traveling; moist turkey and lump free gravy if you're cooking. On Friday, just buy something. It's the way we recover - you buy something and a company hires one more employee. Manufacturers buy more raw materials to produce more product and retailers build inventory. And here's an idea - call your favorite vendor and buy more enterprise security management software.

Eat well and spend safely on this Thanksgiving holiday.

Hackers in the Baltics - Protecting Informaiton Assets

Wednesday, November 25, 2009 by Pam Casale

 

Protecting information assets from cybercriminals is a global initiative. There are advanced technologies to detect the criminals and advanced criminal activity in places you would least expect them. Our friend Warren Axelrod tells an interesting story of a cruise to Baltic capitals where most recently cybercriminals were arrested for the heist of ATM credentials. As your cruising with Warren, think about your efforts to protect information assets.

From the desk of Warren Axelrod:
In the fall of 2005 my wife and I took a wonderful cruise of the Baltic c.capitals which included St. Petersburg in Russia and Tallinn in Estonia. Siobhan Gorman and Evan Perez had an article in the Wall Street Journal (November 11, 2009 section A10) about the huge ATM heist and the arrests made in the same Baltic capitals - a very different context for appreciating the Baltic capitals.

 

You probably recall the heist in question. The Royal Bank of Scotland’s RBS WorldPay systems in Atlanta, Georgia (the U.S. Georgia that is) were hacked and the ATM credentials of customers were stolen. These credentials were used to create prepaid ATM cards, which were used to withdraw cash from 2,800 ATMs in 280 cities globally within a twelve-hour period. The hackers cleverly exploited their access to the systems to raise the permitted limits on the ATM cards, thereby increasing the haul. It is indeed a credit to law enforcement that the alleged perpetrators were found and indicted and it is hoped that this case will deter others from such activities.

 

Now, back to the cruise… St. Petersburg and Tallinn were the highlights of the trip. St. Petersburg is a beautiful European-style city, founded by Peter the Great in 1703, with its wide Parisian boulevards, Venetian canals, and impressive Baroque and neoclassical buildings. Tallinn is a medieval city with historic churches and fortresses. From the physical appearances of these cities, one would never guess how technologically sophisticated their populations are.

 

There was little to no visible evidence of advanced technologies changing the lives of Tallinn’s citizens. However, the tour guide in Tallinn did allude to it. She mentioned that Tallinn is the home of the Internet phone company Skype, which was founded by a Swiss national who moved to Estonia. And Estonia found its place on the cyber map when a massive denial-of-service attack put the country’s financial system out of action. Supposedly this was the first real example of cyber warfare. It was then that the world at large realized how advanced Estonia was in terms of moving so much of its government and private sector business online, and how dependent the country had become on the internet.

 

While we have a tendency to equate impressive modern skyscrapers, roads, bridges, tunnels and other physical infrastructure elements with the presence of advanced cyber technologies, one shouldn't’t underestimate the cyber sophistication and effectiveness of seemingly traditional societies. Appearances can indeed be deceptive. Take this observation one step further: In companies large and small there are people who look like the employee of the year or the innocent local business owner who are hiding their real identities as hackers and cybercriminal. This knowledge is important to professionals charged with protecting information assets.

Personal Privacy - Protecting Information Assets

Tuesday, November 24, 2009 by Pam Casale

Up close and personal - protecting information assets with Google using a Google Dashboard – You’ve Got to be Kidding!

 

Imagine that you use Gmail - Google’s mail product. Here’s a fundamental question about protecting information assets - your personal mail as an example: 
You own your email data right? Should you need to GIVE PERMISSION to Google to use, look, search your email  ---OR

Google owns your email content and can do whatever they want with it – UNLESS – you learn to use the Google DASHBOARD to protect your information assets - your private correspondence?? 
 

In another installment from Tales from the Cloud, Warren Axelrod, disagrees with Matt Asay’s review of the Google Dashboard.

 

It really is insidious … that constant chipping away at our privacy - often without our knowledge.

 

So now we have a new responsibility. According to Matt Asay’s November 5, 2009 column “Google privacy controls: Most people won’t care,” Google is harvesting every Google Doc. Google Voice call and Gmail e-mail and is assuaging people’s privacy concerns by making available the Google Dashboard.

 

Google Dashboard supposedly enables individuals to control their personal data  - protect their information assets supposedly held for them by Google. Users may review their data, and delete information about themselves and change the policies whereby such data are gathered, held, and distributed.

 

Matt Asay’s post rightly hails this as a step in the right direction. However, is it really going to do much to sustain privacy? Asay notes that Google Dashboard is “almost certainly never [ever] going to be used by the vast majority of Google users.” The writer claims that this is because of user apathy and their not valuing their personal privacy.

 

I challenge Asay’s hypothesis. I think that the features of Google Dashboard won’t be fully utilized because while individuals care  about their privacy they simply don’t have the time to learn a dashboard, choose settings, tweak Google’s storage settings in order to keep something private that should be private to begin with. Most already have enough to deal with  - the economy, their work, family problems, health care issues – come on, where does Google get off making their mail system as important as finding a job????

 

Maybe Google is trying to do the right thing. I suggest the right thing is to treat email as private correspondence and then provide the means for a user of gmail to give Google permission to store and search it. How can you be sure that the data haven’t already been cached or distributed or copied many times over? What assurance do you have that the controls they are asking you to impose are even effective?

 

Google- close but no cigar!

 

PCI DSS Compliance Solutions - Qualified Security Assessors

Monday, November 16, 2009 by Pam Casale
Recent updates to the Heartland Breech and RBS WorldPay describe both companies recertifying to return to the list of PCI DSS compliant processors. SC Magazine ran the story and there was a lively conversation among the many people posting comments about PCI DSS Compliance solutions, the efficacy of compliance in security customer data and these two companies. There were many comments and lots of criticisms aimed at the PCI Council.

The following comment about Qualified Security Assessors (QSAs) caught my eye:

Why is no one asking the obvious question? "What QSA cleared these two companies as compliant in the first place?" The next obvious question is this: Why is that QSA company not in remediation? The QSA companies that are currently "in remediation" had nothing to do with these breaches. Is someone just trying to save face and taking it out on scapegoats?

QSAs have a difficult job. Companies are spending lots of effort, time and money on implementing  PCI DSS Compliance software, creating the processes, defining roles and responsibilities required to extract value from PCI DSS Compliance software. There are lots of companies to assess, all in various stages of compliance. Not all the companies hoping to be certified are audit ready. Many companies are still considering and often postponing decision to automate log monitoring, log review and reporting. The QSAs can only review an organization by using the data that is provided.

What do you think of the QSAs who have visited your organization? If you're a QSA we'd like to hear from you. Comment here!

Firday Quick List of Security Activity Monitoring

Friday, November 13, 2009 by Pam Casale

Here’s a quick list of security activity you should be able to monitor with your SIEM solution to get control of “creative users” that ignore policy or controls.

-       Unauthorized IP address on the network

-       Account used from multiple sources

-        High rate of failed logins – 50 or more in 1 minute

-       High rate of firewall denies for a single source ip

-       Login denies from or to an operational sensitive host

-       Many failed login attempts for a user

-       Many failed logins from a single source – 50 or more in 1 minute

-       Successful attempts to login to any account on many hosts from a single source

-       Successful attempts to login to same account on many hosts

-       Unauthorized pseudo logins

 

Here’s one more way to use a SIEM solution with correlation capability: This example is employed by a company focusing on user login activity. The goal: know when a user logs in that HAS NOT LOGGED in for 5 days or more. The Intellitactics SIEM solution creates a dynamic list that expires in five days and populates the list with each user’s login ID. Then the Intellitactics SIEM looks at the list everytime a user logs in and generates an alert if they ARE NOT on the 5 day list. This practice is unique for this company but using dynamic lists is very effective in generating alerts for early warning.

Packaged correlation, dynamic lists, unparalleled collection and patented adaptive parsing of all log sources makes Intellitactics SIEM a TOP 10 Technology for 2010.

Number 10 on the Top 10 List - Security Activity Monitoring

Thursday, November 12, 2009 by Pam Casale

More examples of security activity monitoring - using the Intellitactics SIEM solutions.

One of our SIEM customers had a potential problem with employees choosing to use the public wifi at work since it didn’t have any of the restrictions presented by the corporate wifi. Then they would connect back in with a VPN to do their work. Now the Intellitactics SIEM solution can check for a VPN login under a user name and alerts if the user had badged into the building in the last 8 hours. The SIEM solution monitors the physical badge reader for this effective correlation. Not all SIEM solutions are created equal: Intellitactics SIEM solutions monitor just about anything that generates a log and correlates the data with other monitored events.

Here’s another example made possible by using your SIEM solution to monitor a physical device – like a badge reader. The company wanted to know when employees tried to badge into areas of the building they had not badged into in the previous two weeks. Similarly, they monitored to identify instances of multiple failed badge swipes at any particular badge reader or zone of readers in a three day period. The SIEM solution had correlations to look for all of these conditions.

Tomorrow  - the quick list of activities to monitor with your SIEM  to identify insider threats. 


Respecting the Past and Preparing for the Future

Wednesday, November 11, 2009 by Pam Casale
Intellitactics is taking time today to honor the Veterans from all our Services who selflessly stepped up to protect our freedome. My father, himself veteran of World War II, is now deceased. He loved his family and his country and while he had many accomplishments during his life, he was most proud of his service in the United States Army. He spent time at a Veterans Hospital, where he received excellent care. At his funeral, we were honored to have a color guard present the flag that draped his coffin to my mother. The words "on behalf of a grateful nation" spoken that day are words I will never forget.

My father was first generation American. His family, my ancestors, were grateful for the life they were able to make in America. My father turned this gratitude into service for his country. When he returned from the war, his company saved a job for him. When he was aging and ill, the Veterans Administration was there for him.

Today, we have a national crisis. We have an unprecendented number of veterans needing more complex help. The wars we fight around the world, leave scars that are physical, emotional and psychological. Veterans return from war, need work and counseling to re-enter the civilan world. As a grateful nation, on this day set aside to honor our veterans, I will take moment to remember our commitment to those who stepped up to protect our freedom. 

[This post is personal and is not intended to reflect the opinions, positions or actions of Intellitactics.]

Share how you honor Veterans on this special day. 

Security Activity Monitoring - Using a SIEM Solution

Tuesday, November 10, 2009 by Pam Casale

If you visited the blog earlier in the week, you know that security activity monitoring is on the TOP 10 List of Technologies for 2010. This week we're featuring how you can use your SIEM solution for security activity monitoring.

An insurance company uses the correlation capability that comes with their Intellitactics SIEM solution to identify users that are doing password rotation. Password rotation is when a user, forced by policy to change their password, reuses a password they’ve used before. The policy for this company, which is not uncommon, is that a user can’t use the same password for 12 iterations of changes. This company tracks the user name of the users and their machines and the correlated result creates an alert. The alert triggers a case in their ticketing system and the user and their manager are notified.

This next one is one of my favorites: A company had a problem with users logging into machines in other departments for look for files they weren’t supposed to see. I’m pretty sure this doesn’t happen in your company, but in case it does here’s a good approach for solving the problem. It turns out the users were able to do this because they had local admin rights – this was discovered using the SIEM solution. Since every user had dedicated use of a machine, a correlation alerted if a user logged into a machine they had not logged into in the last 7 days. Problem solved.

Tomorrow – having your SIEM solution monitor physical devices -  like badge readers -  to stop the use of public wifi at work.

Don't forget to comment here and share your practical approach to security activity monitoring.

Top 10 List - Security Activity Monitoring

Monday, November 9, 2009 by Pam Casale

With about 7 weeks left in 2009, companies are looking forward to 2010. Gartner, an IT industry research and analysis group, published a report: the TOP 10 Technologies for 2010. Making number 10 on the list for 2010 is SECURITY ACTIVITY MONITORING. We’re not surprised because almost all our customers use the Intellitactics SIEM solution for security activity monitoring.

Specifically, the article on the report captured on eWeek describes why security activity monitoring made the Top 10 List.

While classic security techniques have tried to bar malicious intruders from attacks, companies are embracing monitoring and analysis tools to identify and isolate suspicious activity.

That’s a significant shift in emphasis – from barring attacks from intruders to isolating suspicious activity. Many professionals agree that all the bad guys aren’t intruders – some of them work on the inside.

In talking with the Intellitactics Solution Architects, our experts on implementing and extracting optimal value from a SIEM solution, I was able to get some examples of security activity monitoring – real life, practical examples from our customer files. This week we’re featuring what Intellitactics customers are doing with their SIEM solutions: Intellitactics Security Manager, our total software solution, and Intellitactics SAFE, the complete SIEM appliance.

Maybe you’ve implemented some of these examples yourself, or would like to if you had the right SIEM solution. Comment on this post and share your practical tips and techniques for security activity monitoring.

Here’s the example for today. Many companies monitor employee web browsing for specific activity like gambling, surfing pornographic sites or other inappropriate activity occurring during the workday. I found  a government site that reports corporations lose millions of man hours a month, translating into  millions of dollars of lost productivity from this type of unauthorized web browsing. This doesn't even take into consideration the vulnerabilities these activities can introduce to the enterprise.

Another practice is monitoring host intrusion detection systems (HIDS) like those from Tripwire, to identify and alert on attempts to get access to restricted files. An ounce of prevention is worth a pound of cure. Be sure your SIEM solution monitors a broad base of data sources like HIDS.

Check back tomorrow to see how a SIEM can be used to enforce password policies. Use Comments to share your best practice.

Tales from the Cloud – Part 4: Every Cloud has a Silver Lining

Friday, November 6, 2009 by Pam Casale

From the desk of Warren Axelrod:

Sometimes you read about a vulnerability and say to yourself: “Could this be used for good?” That’s what happened when I read about researchers showing how “it is possible for attackers to precisely map where a target’s data is physically within the ‘cloud’ …” found in the October, 2009 article by David Talbot in MIT’s Technology Review.

Isn’t that just what we need to demonstrate PCI DSS compliance as well as conformity with the requirements of the Gramm-Leach-Bliley Act, HIPAA, Sarbanes-Oxley and the like?

 

The real issue, discussed in the article, is the reliability of such tagging. However, if the methods can be refined, does this offer a solution to the opacity issue which plagues cloud services? Can companies use such information to demonstrate compliance with data protection requirements?

 

In my October 13 blog, “Protecting Information Assets – Cloud Services Providers,” I discuss the need for physical and logical controls and the ability to demonstrate compliance with specific data protection regulations. And in my October 19 blog, “Catching Fraud – PCI DSS Compliance Software,” I express concern that compliance with laws, regulations and guidelines, though necessary in and of itself, does not guarantee security. So that any methods that will provide more of the information necessary to demonstrate good security and privacy practices are to be welcomed.

 

There are, of course, somewhat easier ways to track where customers’ data are residing. One way is to carve out specific equipment in known locations for particular client institutions, which are subject to regulatory oversight, particularly those in the financial services and health services industries. And it appears that cloud service providers are increasingly willing to offer such services, recognizing the huge potential population of applications that could then take advantage of the cloud. Such specificity will increase the cost of services, since some of the advantages of virtualization and rapid scalability will be reduced making the costs higher. However, with resources costing cloud service providers so much less, it is more than likely that the net cost of “knowable dedicated cloud resources” will still be much lower than most organizations could negotiate on their own.

 

Another potential advantage is that cloud services providers may be more receptive to your directly monitoring logs of the resources that are dedicated to your particular use – but that remains to be seen.

Tales from the Cloud – Part 3: Malicious Fake Profiles – Captcha Gotcha

Thursday, November 5, 2009 by Pam Casale

From the desk of Warren Axelrod:

It’s virtually impossible to know who you can trust on the Web. Read the October 1, 2009 column by Elinor Mills, “Facebook shuts down malicious fake profiles.” It will certainly raise your level of concern on several counts.

 Seemingly there are “numerous profiles” on Facebook that “were identical except with different names …” If someone clicked on a link within the profile then they could be tricked into paying for unneeded software, revealing credit card information, and subject to having spyware installed on their machines.

 

Roger Thompson, chief of research at the anitvirus provider AVG Technologies is quoted as saying that the bad guys “…have found a way to automate the creation of Facebook accounts, which means that they have found a way to bypass the Facebook Captcha, a hard-to-read image of letters [and other characters, such as numbers] supposed to ensure that a human is involved.” The use of a Captcha is required for opening a new account on Facebook.

 

Facebook spokesman Simon Axton claims that the Captchas were not in fact read automatically, but had been subject to human intervention.

 

There have been rumors for some time that hackers were working on recognizing Captcha characters by machine in order to overcome the effectiveness of the method. Were this to happen, then yet another heavily relied-upon authentication method will go down the tubes. It may be, in the Facebook example, that the Captcha technology was not in fact compromised. But it’s likely that it’s only a matter of time before it will be.

 

There are some who look forward to the possibility that the Captcha images will be broken signaling a material advance in pattern recognition. That may seem somewhat perverse, but early hackers and some current software vulnerability seekers claimed that they are a positive force, striving to improve security for all.

 

Whichever position you may take, the single most important lesson to derive from this is that any security measure is only effective until it is broken … and breaking it is only a matter of time and persistence.

Compare and Decide - Is it time to back to earth from MARS?

Thursday, November 5, 2009 by Pam Casale
Thinking about augmenting or replacing Cisco MARS with a SIEM solution?

Make one easy decision for Intellitactics enterprise security management appliance. Here's a list of all the Cisco devices we monitor. We start with Cisco MARS and move through your network.

Cisco MARS:

We support the ‘alert’ generated from the analysis policy created on MARS by the user - Intellitactics sees this as a data stream of its own. This isn't the original event stream from MARS which had its own format. 

Before you get to the following list of devices supported by MARS and the Intellitactics  SIEM Solution, here's another important fact:

Cisco had opted to support these device using protocols like snmp, but we opted to develop a different integration like a JDBC connection because it gives our SIEM solutions greater flexibility in the long run AND the ability to acquire more data providing greater value to our customers. 

Cisco Aironet Wireless Access Points

Cisco Catalyst Switches

Cisco Security Agent

Cisco VPN Concentrator

Cisco Content Engine

Cisco Content Switch

Cisco Global Site Selector

Cisco Intrusion Prevention System

Cisco IOS (Routers & Smart Switches)

Cisco IronPort Web Proxy

Cisco MDS (Multilayer SAN Switches)

Cisco ASA/FWSM/PIX

Cisco Secure ACS (Access Control System)

Cisco Tacacs+ (this support is across several Cisco networking products listed above)

Cisco UBR (Universal Broadband Router cards)

Cisco Unified Call Manager

Cisco Wireless LAN Controller


Here's something to think about: For any given device category (eg. firewall) we support many more products than what Cisco lists as supported devices for MARS. Slip SAFE into place right next to MARS and get everything you've been missing like hundreds of compliance reports, visual analysis for finding root cause, monitoring access controls and applications with one simple appliance.

Want to learn more about other ways we get more from your logs? Comment here and ask about the extensive SIEM solution device list.


Tales from the Cloud - Part 2: Stolen Passwords, Exposed Data

Wednesday, November 4, 2009 by Pam Casale

From the desk of Warren Axelrod

Oops, again! Seemingly tens of thousands of email passwords belonging to users of hotmail, gmail, and others were hijacked and are being used by spammers – see the October 6, 2009 article “Passwords for Google, Yahoo and Hotmail accounts illegally leaked online,” by Nate Lanxon. This is not a good thing, to say the least.

 No one appears quite sure – or maybe just not willing to disclose – what actually happened here. Some attribute the loss to phishing, others to keylogging. It sounds to like a direct attack on the password files, but I really don’t have any evidence to support that. The reason I suspect a more direct attack is that the report verified that affected account names began with the letters A and B. That would appear to suggest that password files had been stolen, since phishing and keylogging would generally yield a more random selection of names. But who knows?

 

More important than the specific attack vector (although that is important for preventing it from happening again), is the issue of relying on the cloud for storing one’s sensitive data, whether you are an individual or a corporation or a government agency. Clearly, data stored in the cloud can be exposed to theft and misuse. In some cases, such as with the PCI DSS (Payment Card Industry Data Security Standard) and various laws and regulations, it is often impossible to comply because of the opacity of the cloud.

 

I attended a presentation at which the information security officer of a major financial firm mentioned that he had discovered that millions of records of sensitive information had been inadvertently stored with a cloud services provider. Upon discovery, they pulled the data back inside the company. However, knowing how virtualized the storage of data is in the cloud, with many copies residing across numbers of machines in many locations, it’s practically impossible to ensure that all copies of every data item have been removed.

 

Data persistence, like that in the cloud, represents a significant risk to regulated companies in particular and represents risk to any entities that choose to store sensitive data in the cloud. The danger is compounded when they don’t know that they are doing so. Organizations do not have control over all their structured and (especially) unstructured data as it is, so the risk of exposure in the cloud is that much greater.

 

What has really happened is that we have taken a bad situation and made it worse. In the “good old days” of relatively simple IT outsourcing, one usually had some idea of what data you were sharing with third parties and you could attempt to make sure that the data were protected and suitably destroyed when no longer needed. Now, it appears, all that is up for grabs in the cloud where virtualization, resiliency and load balancing have taken away any real ability to manage your data.

NEW Series: Tales from the Cloud

Tuesday, November 3, 2009 by Pam Casale

Today we're starting a new series that should be interesting to companies that care about eneterprise security management solutions and services. This series- Tales from the Cloud - is from the desk of Warren Axelrod. Warren's written several time for this blog on PCI DSS Compliance solutions, security issues with virtualization, cloud computing and other topics related to protecting information assets. He's worked in several financial services companies protecting information assets. His experience has been strategic and tactical; he's been in operations and on the compliance and risk side of the business. I think you'll find this series on cloud computing to be thought provoking. Let us know what you think!

Tales from the Cloud – Part 1: A Kick in the Side

 Oops! SideKick users were subjected to the “Men In Black” memory eraser or “Neuralizer” … and they weren’t protected by their Ray-Bans.

 

The T-Mobile’s SideKick outage, which occurred as a result of a server failure in early October 2009, essentially wiped out users’ stored contact lists. At first, it was feared that the data was lost forever; subsequent reports indicated that the data was recoverable. Whether the data was recoverable or not, there was clearly a period during which customers did not have access to their data, causing great inconvenience and anxiety.

 

This incident and others involving Gmail and other service outages should raise a red flag as we continue to increase our dependency on cloud services. Which presents a greater issue to users: cloud security or cloud services?

 

I have felt for some time that availability is the greater issue. We have ways of securing our sessions on the Web, even though they offer limited effectiveness in the face of ever-evolving threats. But, when there is no service available at all, the impact can be immediate and devastating. It is true that outages can result from bad guys launching denial-of-service attacks, but the impact is generally focused and usually affects a limited number of websites. The big headline grabbing service interruptions, at least to date, have originated from networks and servers out of service due to a break in undersea cables or failures of servers or other equipment and software due to some error or other. Seldom are these outages due to intentional attacks, except perhaps for the recent politically motivated attacks on Estonia and Georgia.

 

So where does this leave us? Just as you have defensive driving rules, you should operate under defensive computing rules. I recall in the early days of timesharing, one would store their work every five or ten minutes because you expected to lose the connection and any work done since last time you saved it would be lost! So it is with cloud computing:

  • Back up your data onto media under your direct control
  • Have an established means of continuing to conduct business even       when your cloud services are not available.

It might just be a matter of maintaining a list of your contacts’ telephone numbers so that you can call them up or text them if you can’t reach them via email or instant messaging. It is true that it is easier to send a single email out to 20 recipients than calling up all 20 colleagues separately, but the latter is better than nothing. If you operate with the expectation of system and network failures, chances are that you will fare better than most when those inevitable outages and data losses occur.

Cisco MARS - Going Cold

Tuesday, November 3, 2009 by Pam Casale

Last week Gartner issued a research note for clients about Cisco MARS.

It seems that Cisco is freezing support for non-Cisco data sources and we’ve heard that  the Cisco salesforce is advising customers to look for another log collection and analysis and event management for non-Cisco sources. Several companies we talked to last week have already taken steps to augment Cisco MARS with Intellitactics SAFE.

We help you take full advantage of your Cisco MARS tool – we treat it like any other data source and consolidate the logs with all the logs from non-Cisco data sources. Better yet - we collect logs from dozens of Cisco devices and any non-Cisco data source you can think of. We offer high speed parsing, log analysis, event management and hundreds of compliance reports using one, simple to deploy SIEM appliance.

We know that there are lots of you out there that were trying to “check the box” for a SIEM solution with MARS. Cisco widely sold MARS as a SIEM and built a huge customer base. It’s time to make your almost SIEM a fully capable SIEM by choosing one Intellitactics SIEM solution like Intellitactics SAFE.

SAFE solves your compliance challenge and gives you the foundation you need to establish best practice security operations. SAFE helps you do more with logs – all your logs – and establish the infrastructure for every day compliance. Whether you plan to augment or replace Cisco MARS you can learn more about SAFE every Tuesday at 2 PM EST. 

5 QUESTIONS and 5 ANSWERS for SIEM Solution Buyers

Monday, November 2, 2009 by Pam Casale

In last week's series on 5 Questions from SIEM buyers, I hope we answered some of your questions about buying SIEM Solutions. Here’s a quick summary:

 

·        Will Intellitactics’ PCI DSS Compliance reports satisfy a Qualified Security Asseessor? YES       Can you write your own reports? OF COURSE but you won’t need to.

 

·         When you’re using Intellitactics SIEM Solutions will you be able to collect ALL LOGS from any device or data source? YES YES YES!!

 

·         Can you do root cause analysis? YES and you can do it graphically – in the case of Intellitactics SIEM solution – a picture really is worth a thousand lines of events.

 

·         How fast is Intellitactics SIEM solutions? FAST ENOUGH – Consistently for effective and efficient log and event management.

 

·         How many devices does Intellitactics support – ALL the ones that are important to you and then some.

 

If you missed any of the detailed answers – check last week’s blog posts - AND

 

If you’re one of the many companies still considering a SIEM acquisition, there’s one more question you might be asking: How hard is this going to be – really?

 

We won’t kid you – it’s not hard – it’s as easy as we could make it. We went to great lengths to infuse Intellitactics SIEM solutions with the correlations and alerts we know make a difference in security effectiveness. We KNOW they make a difference because best practice companies – our customers - say so.

 

If you need more proof that a SIEM solution can be meaningful to your company – go to our research center and read what Aberdeen Group, SANS, Gartner and customers report. Come to a Tuesday demo and see for yourself. If you have more questions – comment here!
