A jack-of-all trades:
The best thing about AlienVault USM is it being a “Jack-of-All Trades” solution. It provides SIEM, HIDS/NIDS, FIM, NetFlow, Asset Management, Vulnerability Management, etc., under one USM platform. None of the commercial SIEM vendors like ArcSight, McAfee, etc., can boast of such a diverse feature set.
- QRadar is the closest to AV USM in terms of feature diversity. While all the features are formerly isolated Open Source community projects, the USM does a good job of integrating them into a feature set. While they are not great as individual parts, they more than make up as a sum of the parts.
- OTX – Open Threat Exchange is a wonderful community sharing platform that helps clients to share IP and URL reputation information so that all AV customers can benefit. This is true community sharing modeled on the likes of the Splunk Community (for app development). This has the potential to grow into a large source of Real World Intelligence and what AlienVault intends to do with this data remains to be seen. For now, it is being used by USM Correlation engine to provide better context and content for Security monitoring. AlienVault Labs, is also utilizing this infrastructure to constantly update Detection rules for malware vectors, vulnerability exploits etc. QRadar and ArcSight provide Intelligence, but it is commercial intelligence and not community intelligence. With community intelligence, you get more hits than misses.
- Multi-Tenancy – While this feature may not elucidate an interest from many readers, those who have worked in an MSSP environment can understand why this is a very important feature to have. AV USM does support Multi-Tenancy out of the box. This, when combined with the Architecture flexibility provide great MSSP models to sell and operate. The key is to understand how the multi-tenancy works. Basically, a single database is used to store data of several customers using a Data isolation Logic and Permission control. The data isolation logic is based on Entities created in USM (Assets, Users, Components Assigned (Sensors) etc., are grouped together as a Single Entity) and Permissions (applied in a granular fashion to data sets related to the Entities). QRadar, ArcSight and other major SIEM products provide this as well.
- Integration – While AV USM is known for being customization friendly, the amount of out-of-the-box plugins for Log Monitoring and Correlation is limited to the well-known products. It does not have comprehensive integration capabilities with say legacy applications, Directory services, databases, etc., that other SIEM vendors boast of. Similarly, it relies mostly on its own “pre-packaged” tools for data enrichment and hence has poor “Third Party” Integration capabilities. However, if you really are a developer of open source products, the integration challenge can be overcome. But how many are willing in the real world enterprise?
- Correlation and Workflow – What good is a SIEM product if it cannot perform advanced Correlation and Operational workflow? AV USM has a strong foundation in Correlation using XML driven Directives and Alarms thresholds. However, when it comes Head-to-Head with the Industry leaders like ArcSight, QRadar, Splunk, etc. it falls terribly short. We particularly like the Cyber Kill Chain flow which a lot of customers are using for complete visibility, but this is not the end game in real world enterprise operations where not all the data points required for the directive are available. Same thing goes for the workflow, where the integration with external ticketing or issue tracking system is very limited, and hence acts as a deterrent in large scale deployments.
Thank you Vinod for your time to review AlienVault USM and for your candid feedback!
