Snort vs. Nagios Log Server vs. Security Onion

If a colleague was looking to tighten down their network I can easily recommend Snort to them. It gives you some more peace of mind knowing that its always scanning traffic for malicious looking code. Even things your major firewalls and security hardware might miss, Snort has picked up. Its an easy recommendation for me.

Nagios Log Server facilitates the ability to search all entries of logs in a quick and easy way. Beyond that, it has allowed us to configure alerts for notification when there are potential threats (may they be security threats or only application-side problems), and to filter the data for audits and compliance.

Security Onion works well for setting up within a Linux environment. This brings a new platform to run and maintain though. The application its self has helped to keep track of logs and vulnerabilities in the environment. Alert triage and case creation is simple to start and follow through to the end.

• FTD images that are being pushed for ASAs are less efficient from an administration standpoint, no CLI.

Nagios support is decent. Nothing bad to say about them, but nothing extraordinary too. We mostly asked them questions instead of actively asking them to change or fix things for us. The response time is OK, commonly you can get a response in the same day. You can also call, but they are available only during US office hours.

For our organization, the Cisco defense in depth concept works the best. While Cisco can be made to work with other vendors, we have found the best in depth protection by integrating Cisco products for maximum visibility. We had a Barracuda Web Filter, but it was difficult to maintain when you had limited scope on what you could block, so we created a whitelist only setup which required a lot of additional manpower. This wouldn't have covered new threats with DNS spoofing and the like. Sourcefire also integrated with our anti-malware platform (Cisco AMP) for even better visibility on what may be happening on the end users workstation. We are planning on adding in Cisco ISE to complete the approach and possibly stealthwatch to cover our bases in the future. The Palo Alto gear was interesting, but it was priced far out of our range.

Windows Event Log doesn't have 10% of the capabilities of Nagios Log Server. No real-time alerts, no scheduling, no external plugins or APIs. Nothing. The only advantage is that it is a native Windows application.

Other vendors may have a more robust solution but for our needs, Security Onion was the one to move forward with. We have tested some of the others but the cost of those platforms makes the ROI not as desirable. There is a learning curve with Security Onion but it is worth it for the value provided.

• Being open source, ROI on free is hard to beat for something that works.
• I believe it greatly enhances the security of my network.

• We could react in way less time to a lot of potential outages since we started using it.
