We are using AlienVault OSSIM to monitor any events happening on the devices. Since AlienVault OSSIM is an open-source tool, we cannot expect much from it. If basic things like file integrating and monitoring are happening, along with brute-force-related functionalities are happening, or some basic SQLs or something is happening on the web servers, we monitor for those things. There are directories that are already preconfigured. So, we have already deployed that on the servers which we want to look for. That is the basic thing and the main concern why we are using AlienVault OSSIM.
This may not be a feature. It is something like how you configure and how you analyze it. But since it's open-source, I'm talking more about this. So, since it's open-source, getting the features of going deep into an IP is good. For example, I get an alert in which I see this IP, source IP 8.8.8.8. Now if I want to drill deep down into this and know which other IP this IP has been communicating to and these kinds of things and, also, if I have, for example, firewall logs onboarded on this tool, I can just literally go to the filter section and put the IP and check all the logs, which have been collected on this device. From this, I can make the meaning and see if those have been affected or not. It is a basic feature, but since this is open-source, it is a good thing in terms of the results we are getting.
The area for improvement is a lot. When I started using it on our enterprise side, the issue we faced was, for example, if we were running at that time on AlienVault OSSIM v5.7.4. So, for some orders, we had to install some packages, and when we tried installing that package, some dependencies got upgraded to a new version. Now once that dependency got upgraded, the SQL, since you might be aware that OSSIM uses SQL database, now SQL and all the dependency in everything was not on the same version, and that caused the database to crash. The aforementioned area should be eased out by upgrading the patches and upgrading dependencies. This kind of thing is a disadvantage of OSSIM, and I would like them to work on this.
But I have also raised service requests many times and gave it a push on the community section too. However, since it is a local source, they don't reply much over there. That is why I don't like to work on OSSIM because it is unpredictable. Once the storage goes above 50 percent, it starts behaving unpredictably. If you get stuck with a situation, then you need to drill a lockdown into that. Sometimes you get no luck. Then you have to just reimage the server with the new fresh OS of AlienVault.
As for additional features, not much because if you move to the newer version, it is kind of getting more stable. But, to make my life easier, then I would say try to give more features. I know it's open source, so they also cannot provide me with more features. But still, if they can provide me with more features because right now it's becoming old. Right now, we are even moving from SIEM to Security Data Lake. So when we move to it, this will be literally outdated. No one can even expect anything out of it. The way security is moving, it will be outdated very soon. They have to also provide something new to keep this going for the future also.
I have been operating and deploying AlienVault OSSIM since January 2022. I am a user of the solution.
If I talk about OSSIM, it does not have bugs on the newest version. But if you stick to the older versions, then, yes, you might find bugs, and it might crash.
There are a lot of people you will find using OSSIM since they are also offering OTX as a service. So that is also the threat intelligence of AlienVault that they are providing. So I have seen many people using AlienVault.
All the servers and data which we had were on OSSIM v5.7.4. It was literally an outdated one. At that time, we were facing a lot of issues with installation because we did not know if we were moving forward and if some progress was happening or not. But the latest version, they have made the changes, so it is not difficult. It is easy to configure. Plus, documentations are available, which can help the person out as well.
AlienVault, AT&T, that's what we call it now. They have two things, one is USM, and one is OSSIM. OSSIM is open source, and USM is the paid license. So, if you want, you can switch to USM. There you will have to buy a license, and they have a support team that helps you out on issues you face.
I would definitely recommend anyone to get on this tool if they are starting a career in cybersecurity since there are not many tools available in the market which help you get an experience as a SIEM tool. The other ones are paid ones, where you need to buy a license, and then you can try it. So, if you're just starting your own lab, then this thing can provide you with a very great edge because you can experience many attacks and see how the logs are there on the system. So this kind of provides you with that.
Overall, I would rate it an eight out of ten.
