Intelligent Log Analysis May Beef up Security
Security logs could help detect and prevent security breaches, but analyzing their reports is so boring that they're underutilized.
The massive job cuts caused by the recession will pose a huge threat to enterprise security because insider attacks, like disgruntled former employees, account for half of data breaches. Log monitoring and analysis tools provide poor protection from internal breaches because analyzing their reports is a tedious process, experts say.
LogRhythm may have solved this problem by adding the Intelligent IT Search feature to its log management tool. This automatically classifies and tags log entries for easy searching, conducts risk modeling and prioritizes sensitive issues, and puts a universal time stamp on all activities to make them easier to monitor.
Those features will make searches easier, which may help system administrators more rapidly detect breaches through searching the logs. According to the 2008 Verizon (NYSE: VZ) Business Data Breach Investigations Report, which covered a four-year time span, event monitoring or log analysis detected only four percent of breaches.
And that process is tedious. Few IT administrators have the time to read logs frequently and look for unusual data activity, Prat Moghe, Tizor Systems' founder and chief technology officer, said in an article in Compliance Week. According to him, one retailer had an IT staffer spending six hours a day to look through logs.
But the winds of change are sweeping through the log management tools industry.
New capabilities emerging
"Log management tools were used more for compliance than security, but that's starting to change," Adrian Lane, senior security strategist at security consultants Securosis told InternetNews.com. That's because vendors such as LogRhythm are bringing out new features that make their tools more proactive.
Lane thinks LogRhythm is moving in the right direction. "The ability to weight events so that both the processing and reporting are prioritized, and having log files that are searchable and queryable in a standardized way is very helpful to security and compliance professionals alike."
Another functionality LogRhythm's new feature offers is the ability to instantly query all audit events such as modifications to a user's access and authentication privileges linked to a network login account during a specific period of time, thus spotting any breaches in real time.
"This lets systems administrators get all the logs of that user's activities, his activities at a particular time of day and the system's activities at that time," Chris Petersen, LogRhythm co-founder and chief technology officer, told InternetNews.com.
