AlienVault OSSIM (discontinued) vs. Splunk Enterprise

The most obvious scenario in which OSSIM is well suited is in a single office/home office (SOHO) or small business, in which budget is reduced but asset discovery and vulnerability management are greatly needed and appreciated. OSSIM is lightweight and free, so the real challenge to face is to hire or assign an administrator to manage and operate it, instead of any investment on an expensive appliance. Also, as resellers, promoting usage of OSSIM to customers charging for professional services for installation, administration, and maintenance (remember that OSSIM doesn't have official support from AlienVault) is a great asset for the organization.

Pros: Splunk is very well suited if you have multiple log sources of related data. All of them can be correlated and tasks can be automated based on the requirement. Other than alerts, Splunk can also run a specific script of your choice, based on some defined conditions. Cons: If you have a few logs but a large number of log sources, Splunk can be very expensive.

• Threat analysis. It can correlate different events happening to detect a pattern or an attack.
• Dashboard provides a clean, single location to see what is going on in our environment.
• Up to date open threat exchange means everything new popping up out there is included and watched for in our environment.

Incentivized

• Real-time + Scheduled alerts - i-e you can set up alerts which are actively monitoring your logs
• Pretty good response time for search results. With our key/value logging, Splunk makes it blazing fast to query the data.
• Dashboards provide insights into historical data
• Love how Splunk indexes all of the data and provides keys to search on

Incentivized

• Creating custom rules is a bit complicated
• Reporting could be improved
• Agent has caused conflicts with a couple of our other applications

• Even though there is a search tool as a help function, you still have to read through many documentation to find the answers you're looking for and sometimes you don't find it. The help function in Splunk could be improved to be more intuitive or have a built-in help per report, panel or dashboard.
• Creating a Splunk dashboard is rather straightforward however, customization is not. Splunk could be improved to provide more tools or features for customization such as adding colors and font options for text and graphs or graphics.
• My dashboard has a lot of useful information and I want the important panels and reports at the top but there is no easy way to do this. Perhaps Splunk could be improved to allow features such as adding URL links to other dashboards or some other clever way to emphasize the important data in my dashboard without compromising space.

We are using Splunk extensively in our projects and we have recently upgraded to Splunk version 6.0 which is quite efficient and giving expected results. We keep track of updates and new features Splunk introduces periodically and try to introduce those features in our day to day activities for improvement in our reporting system and other tasks.

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.

Splunk Enterprise has plenty of storage space for security logs and can search and correlate suspicious activities up to 30+ days back. Splunk Enterprise can integrate with a ticketing system to track threats and correlate with IoC between security events. Splunk Enterprise can provide reports of account lockouts. Splunk Enterprise can consolidate multiple security alerts into one entry with a number showing how many events occurred.

When properly setup and configured, Splunk is extremely reliable.

Everything is done through MSSP and installation pro services. Once those hours are burned up, then you're on your own without a lot of help. Typically the pro services hours aren't enough to get past 60 days and MSSP are hit and miss. We had a miss for installation helpers.

Splunk maintains a well resourced support system that has been consistent since we purchased the product. They help out in a timely manner and provide expert level information as needed. We typically open cases online and communicate when possible via e-mail and are able to resolve most issues with that method.

The online course was simple clear and described the main capabilities of the solution. There is also an initial module that can be done for free so anyone can familiarize themselves with the functionality of this solution. On the other hand, however, there could be more free online courses. Maybe even with a certificate, this would broaden the group of people who are familiar with the platform while increasing familiarity with the solution itself.

Smooth without too many major issues.

AlienVault OSSIM as the first experience with a SIEM is very fine, especially if your company is an SMB. Every SIEM shares some features in common with other products, features such as log retrieval and normalization. So if you stick with principles, you can learn other SIEM products as well. If your environment is not of a minimum size, LogRhythm might be overkill for your network, same with McAfee Enterprise Security Manager.

A lot of products have natively inside their own dashboards and or their own logging repositories. And each one is difficult to learn or they're too complex or they're not verbose in the sense that they're not easy to mine the data that you're looking for. So that could be anything from the native logging that you find in other Cisco products. It's easier to use Splunk to draw the data that you're looking for as opposed to going to the individual's products themselves to get the logs that you're looking for.

Splunk can scale in to the petabyte per day range which of course is awesome

• OSSIM and the installers didn't really help us optimize at installation. OSSIM went without optimization for almost two years before that fact was noticed. I think this decreased ROI.
• Finding and researching incidents is much faster with all data available. Sometimes too much data, though.

• Splunk has allowed developers to diagnose production issues when access of control was taken away from them to be allowed to view items in production environments and I believe that is invaluable.
• At times some developers weren't super happy about using it, but it was more of the fact that they were used to having production access and not creating their splunk queries to get information.
• Going one place to view logs was very beneficial to have.
