100 Log Management uses #55 PCI Requirements VII, VIII & IX

Today we look at PCI-DSS Requirements 7, 8 and 9. In general these are not quite as applicable as the audit requirements in Requirement 10 which we will be looking at next time, but still log management is useful in several ancillary areas. Restricting access and strong access control are both disciplines log management helps you enforce.

Tuning Log Management and SIEM for Compliance Reporting The winter holidays are quickly approaching, and one thing that could probably make most IT Security wish lists is a way to produce automated compliance reports that make auditors say “Wow!” In last month’s newsletter, we took a look at ways to work better with auditors. This month, we’re going to do a deeper dive into tuning of log management and SIEM for more effective compliance reporting.

Panning for gold in event logs

Ananth, the CEO of Prism is fond of remarking “there is gold in them thar logs…” this is absolutely true but the really hard thing about logs is figuring out how to get the gold out without needing to be the guy with the pencil neck and the 26 letters after their name that enjoys reading logs in their original arcane format. For the rest of us, I am reminded of the old western movies where prospectors pan for gold – squatting by the stream, scooping up dirt and sifting through it looking for gold, all day long, day after day. Whenever I see one of those scenes my back begins to hurt and I feel glad I am not a prospector. At Prism we are in the business of gold extraction tools. We want more people finding gold and lots of it. It is good for both of us.

One of the most common refrains we hear from prospects is they are not quite sure what the gold looks like. When you are panning for gold and you are not sure that glinty thing in the dirt is gold, well, that makes things really challenging. If very few people can recognize the gold we are not going to sell large quantities of tools.

In EventTracker 6.4 we undertook a little project where we asked ourselves “what can we do for the person that does not know enough to really look or ask the right questions?” A lot of log management is looking for the out-of-ordinary, after all. The result is a new dashboard view we call the Enterprise Activity Monitor.

Enterprise Activity uses statistical correlation to looks for things that are simply unusual. We can’t tell you they are necessarily trouble, but we can tell you they are not normal and enable you to analyze them and make a decision. Little things that are interesting – like if you get a new IP address coming into your enterprise 5000 times. Or if a user generally performs 1000 activities in a day, but suddenly does 10,000, or even as simple as a new executable showing up unexpectedly on user machines. Will you chase the occasionally false positive ? definitely, but a lot of the manual log review being performed by the guys with the alphabets after their names is really simply manually chasing trends – this enables you to stop wasting significant time in detecting the trend — all the myriad clues that are easily lost when you are aggregating 20 or 100 million logs a day.

The response from the Beta customers indicates that we are onto something. After all, any thing that can make our (hopefully more) customers’ lives less tedious and their backs hurt less, is all good!

100 Log Management uses #54 PCI Requirements V & VI

Last we looked at PCI-DSS Requirements 3 and 4, so today we are going to look at Requirements 5 and 6. Requirement 5 talks about using AV software, and log management can be used to monitor AV applications to ensure they are running and updated. Requirement 6 is all about building and maintaining a secure network for which log management is a great aid.
