Snort vs. Security Onion vs. Splunk Cloud Platform

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.

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.

Splunk is excellent when all your data is in one location. Its ability to correlate all that data is intuitive (once the hurdle of learning the query language is overcome). It is also easy to standardize the presentation of information to the company. When data is siloed/standalone, other systems can be cheaper and faster to implement.

• GUI
• Support
• Easy of use

• This SIEM consolidates multiple data points and offers several features and benefits, creating custom dashboards and managing alert workflows.
• Splunk Cloud provides a simple way to have a central monitoring and security solution. Though it does not have a huge learning curve, you should spend some time learning the basics.
• Splunk Cloud enables me to create and schedule statistical reports on network use for Management.

• At times can be unstable with Cisco bugs, require frequent upgrading.
• FTD images that are being pushed for ASAs are less efficient from an administration standpoint, no CLI.

• Requires Linux
• Training

• The SPL programming language that the queries are built in is not very intuitive.
• There should be a better repository of pre-built queries for what I would think of as common Active Directory usage monitoring.
• I would like to see more free training/familiarization information made available.

Ease of use and have all the features we need

What it does well:

- Powerful SPL query language for advanced users

- Excellent visualization dashboards

- Comprehensive documentation and community support

Where it needs work:

- Steep learning curve for SPL syntax

- Non-Intuitive UI for beginners

- Complex administration and data model configuration

- Search performance degrades with poor query optimization

Bottom line: Enterprise-grade tool requiring dedicated training investment. Best for teams with experienced analysts.

Splunk Cloud support is sorely lacking unfortunately. The portal where you submit tickets is not very good and is lacking polish. Tickets are left for days without any updates and when chased it is only sometimes you get a reply back. I get the feeling the support team are very understaffed and have far too much going on. From what I know, Splunk is aware of this and seem to be trying to remedy it.

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.

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.

Search Processing Language really is a game changer for writing easy-to-understand and maintainable queries on your data base logs. Once understood, setting up and validating a query can be done in no time- which leaves us the option to focus on more monitoring and improved services. We have no other tools that utilizes data this efficiently
