A Practical Approach to Effective Security Analytics

When discussing effective approaches to the problem of security analytics, I think it is first important to start with a clear definition of the goal of security analytics. The ultimate goal of security analytics is to deliver technology solutions that assist human security analysts in detecting, responding to and mitigating cyber threats. This simple statement hides an area of technological endeavor that is simultaneously fascinating, important and complex. While a full exploration of the many facets of security analytics is beyond the scope of this post, it is useful to discuss a high-level and general approach to security analytics to simplify the complex problem statement into more digestible pieces.

Started Near the Bottom. Now We’re Here!

LogRhythm made its first appearance in the Gartner Magic Quadrant for SIEM as a Visionary back in 2008.

This is one of the ways that commodity malware checks in with its command and control infrastructure to await further instructions. But it can be difficult to detect this activity. The beaconing can take place at any time or frequency—from once every couple of seconds to once a week (or possibly even longer if you are dealing with an advanced adversary).

How Far Cyber Criminals Will Go to Get Your PII

Everyone who works in security deals with phishing emails to some extent—some more than others. In fact, most of us in the security industry see so many phishing attacks on a daily basis that they are not all that interesting anymore. However, every once in awhile, a scammer will actually take the time to prepare and deploy more believable campaigns and target personally identifiable information (PII) in a more persistent way.
