What is AlienVault OSSIM?

AlienVault OSSIM, Open Source Security Information and Event Management (SIEM), provides you with a feature-rich open source SIEM complete with event collection, normalization and correlation. Launched by security engineers because of the lack of available open source products, AlienVault OSSIM was created specifically to address the reality many security professionals face: A SIEM, whether it is open source or commercial, is virtually useless without the basic security controls necessary for security visibility.

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 So when we move to it, this will be literally outdated.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 The way security is moving, it will be outdated very soon.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.

The solution is not scalable. It impacts so hard. In the initial stages, AlienVault OSSIM can be suitable for small environments. There may be limitations if the customer expresses a desire to expand and add more devices. In such cases, we would need to either explore additional solutions or work within the constraints of the existing setup. We have set up alerts and configured everything in AlienVault OSSIM. It actively monitors for any security incidents. It provides us with regular updates and notifications about any ongoing activities. Only one person is using the solution. It is the perfect solution for small businesses. I rate the solution’s scalability a three out of ten.

The tool's security detection is good. It helps us with login tracking and generating reports. We aim to identify potential issues, such as brute-force attacks on user accounts or server-level anomalies. For instance, if I receive a report indicating a server is at an abnormal level, I investigate and address the issue. Regular meetings are conducted every ten to twenty days to update network issues. Due to restrictions, users face challenges when accessing WhatsApp from outside Saudi Arabia. To bypass this, they use VPNs. When a user logs into Office 365 via VPN, the system sends me a notification indicating their login.
