Exabeam: A Remarkable Claim
October 25, 2022
I read “Exabeam New Scale SIEM Enables Security Teams to Detect the Undetectable.” I find the idea expressed in the headline interesting. A commercial firm can spot something that cannot be seen; that is, detect the undetectable. The write up states as a rock solid factoid:
Claimed to be an industry first, Exabeam New-Scale SIEM allows security teams to search query responses across petabytes of hot, warm and cold data in seconds. Organizations can use the service to process logs with limitless scale at sustained speeds of more than 1 million events per second. Key to Exabeam’s offering is the ability to understand normal behavior to detect and prioritize anomalies. Exabeam New-Scale SIEM offers more than 1,800 pre-built correlation rules and more than 1,100 anomaly detection rules that leverage in excess of 750 behavior analytics detection models, which baseline normal behavior.
The write up continues with a blizzard of buzzwords; to wit:
The full list of new Exabeam products includes Security Log Management — cloud-scale log management to ingest, parse, store and search log data with powerful dashboarding and correlation. Exabeam SIEM offers cloud-native SIEM at hyperscale with modern search and powerful correlation, reporting, dashboarding and case management, and Exabeam Fusion provides New-Scale SIEM powered by modern, scalable security log management, powerful behavioral analytics and automated TDIR, according to the company. Exabeam Security Analytics provides automated threat detection powered by user and entity behavior analytics with correlation and threat intelligence. Exabeam Security Investigation is powered by user and entity behavior analytics, correlation rules and threat intelligence, supported by alerting, incident management, automated triage and response workflows.
Now this is not detecting the undetectable. The approach relies on processing data quickly, using anomaly detection methods, and pre-formed rules.
By definition, a pre formed rule is likely to have a tough time detecting the undetectable. Bad actors exploit tried and true security weaknesses, rely on very tough to detect behaviors like a former employee selling a bad actor information about a target’s system, and new exploits cooked up in the case of NSO Group in a small mobile phone shop or in a college class in Iran.
What is notable in the write up is:
The use of SIEM without explaining that the acronym represents “security information and event management.” The bound phrase “security information” means the data marking an exploit or attack. And “event management” means what the cyber security professionals do when the attack succeeds. The entire process is reactive; that is, only after something bad has been identified can action be taken. No awareness means the attack can move forward and continue. The idea of “early warning” means one thing, and detect the undetectable is quite another.
Who is responsible for this detect the undetectable? My view is that it is an art history major now working in marketing.
Detecting the undetectable. More like detecting sloganized marketing about a very serious threat to organizations hungry for dashboarding.
