Regardless of how SIEM in today’s cybersecurity marketing campaign is driven mainly by Compliance, which solutions is the best, and whether it should be managed or on-premises, Security Information and Event Management is conceptually accepted among security professionals so here’s my top reasons to consider SIEM implementation as one of your cybersecurity initiatives:
- Another tool for Management
Seems obvious but not many realize SIEM is a management tool at the first place. It means it does not have and does not need to have active o pro-active capabilities. All it has to be capable of, is ability to deliver right Security Information from the right Security Event to the management, even not necessarily security management.
- It is all about visibility
Remember SIEM itself does not provide visibility but it is a technique to take “Visibility” to a different level. So if you already do have Visibility over your network and systems, then SIEM is like an interface to enhance the way you see events, not really more revealing facts about security of your systems.
- Correlation is heart of the matter
The main purpose behind a functional SIEM is ability to correlate events, otherwise the main purpose is ignored by solution designer or you. any security program knows in real word, there is no meaning behind each security event unless being correlated and overlapped with other events, and for that matter, SIEM is where you should be able to harmonize your flow of security information; needless to say, it is the job of SIEM solution provider to make sure system is capable to direct you.
- Combining older systems
Not all users of the SIEM are genuinely looking for this management system just because of its native features. One of the main drivers to upgrade to SIEM has been presence of older SIM and SEM. So whether you are forced or just want to combine two management systems, SIEM is the most popular way of SIM and SEM integration.
- Intrusion comprehension
This is totally different than intrusion Detection, Response or Correlation capability and it is about origination of incident and the level of intelligence behind root causes and indirect role of systems to shape the final tangible incident. This is absolutely one of the hidden benefits of a well-designed SIEM within a well-managed security operation.
There are other benefits like Auditing, Policy enforcement validation, security certification…which could be addressed potentially and based on how you are going to execute your SIEM. But remember the main essence of your SIEM is in the details of operation, and none of the benefits would come out of the box with any solution in the market.
