AlienVault OSSIM

If this is your first experience with a SIEM, this one can get you started. Take the time to learn the ins and outs of the product and you'll most likely be satisfied with it if your company is an SMB. If you need compliance reports, OSSIM is too small for you, you'll need to go with USM or USM Anywhere.

Tenable SecurityCenter

SecurityCenter is definitely the juggernaut of the industry. You don't see many shops that are not using Nessus and or SecurityCenter. As a pen tester, I do not judge shops that use Nessus as a catch all, as there are a lot of things you can get hyper focused on and a tool like this helps you see things you may have missed.

Pros

  • Most of the configuration comes out-of-the-box suited for most environments. Setting it up is really easy, with the wizard, you can have it working in less than 3 hours of deployment, without counting asset installation.
  • Out-of-the-box dashboards are really useful. You can modify or add new widgets to suit your needs, but you'll most likely agree with what already comes configured.
  • The tickets feature for handling alarms is really easy to use.

  • Network sweeps
  • Network/host auditing (NIST, DoD, etc)
  • Vulnerability Scans

Cons

  • OSSIM, being an open source solution, lacks log management (a treat that the full USM has). Perhaps a feature to include a lightweight version inside the SIEM Correlation engine can be appreciated.
  • The appliance also lacks support for Cloud-based servers and apps. This feature is also present in USM, so it's unlikely this will appear in OSSIM, but I'd suggest also a reduced version of it included in this appliance.
  • More integration with third-party solutions such as BMC Remedy and ServiceNow, although this can be emulated through email alerts, as most ITSM solutions have the ability of converting incoming email messages into tickets.

  • Bulky - does not scale easily
  • Lack of detailed error logs for scan issues
  • Lack of stripped client (piggybacking off the bulky) - could use a mini/portable client like nmap

Usability

AlienVault OSSIM8.0
Based on 1 answer
AlienVault OSSIM is far easy to use and manage - provided you know what you're doing. As any SIEM application, there is some background knowledge required in order to take advantage of the product's functionalities, such as the log correlation and analysis. Other than that, the application is quite usable and robust.

Alternatives Considered

AlienVault OSSIM has the upper ante in initial deployment price, being that it's open source. Also, with perhaps the exception of SolarWinds, it has a lower optimal requirements for onsite deployment, hence your OPEX won't be hit very hard by investing in new hardware to suit the appliance. The correlation engine is somewhat more robust that their counterparts in LogRhythm and SolarWinds, and the IDS (both NIDS and HIDS) are more reliable as well in terms of results. Finally, although Tenable SecurityCenter is more robust in dashboards, alerts and reports, it comes short in front of OSSIM in terms of real-time IDS and SIEM correlation.

From time to time I take a contract in which I am building a network which includes either a SOC or a compliance shop (lots of this occurring now with the 800-171 compliance push). In many cases businesses like to take the cheap way out. We'll install other lesser known vulnerability scanners and or vulnerability scanners like Openvas. While they all get the job done, they do not pack the power that Nessus/ SecurityCenter packs

Return on Investment

  • The ROI of OSSIM itself is, obviously, immediate, being that it's a free, open-source product. However, you must take into account other inherent investments to cover up for the lack of official support, such as certified agents or consultants that take care of the management and maintenance of the product once in production.
  • On the other hand, the potential loss of information and interruption of operativity due to malware and other threats is really unmeasurable. The implicit savings in OSSIM as a SIEM (Security Information and Event Management) are really the major positive impact on your organization's revenue.
  • Finally, and from a reseller's point of view, reselling OSSIM has the big plus of being a professional services-only asset, given that the appliance itself is free of charge. The only thing to consider is the initial investment in team members with the required capacitation and knowledge to address such professional services to potential customers.

  • SecurityCenter has saved me from missing major items on tests. I would fixate on something, spend too much time on one item. Nessus broke the monotony and ensured that I didn't miss findings
