There’s a legacy connotation connected to SIEM that has led to distributors promoting themselves as some iteration of a next-generation resolution. However is it essential? I’ve been struggling to search out options that might be labeled as “legacy SIEM”—that’s, SIEM with out some form of automation, response, or anomaly detection capabilities or modules.
It is smart for SIEM to accommodate all these capabilities. What doesn’t make sense is that this unsynchronized try at differentiating right this moment’s options from these of 2015.
Let’s have a fast have a look at what SIEM options get referred to as right this moment:
- Fusion SIEM
- Subsequent-gen SIEM
- Developed SIEM
- Unified protection SIEM
- Cloud-native SaaS SIEM
- “Not a SIEM” SIEM (aka, unified safety operations platform)
So, is that this an issue? Completely different takes on product names is nothing new, however on this case, it creates loads of confusion available in the market. First, these names don’t inherently imply something. Certain, some supply indications, like “cloud-native SaaS SIEM platform,” however usually talking, there is no such thing as a goal distinction between a next-gen SIEM and an developed SIEM.
Second, there are a number of permutations of modules which are completely different from vendor to vendor. One would possibly supply SIEM + SOAR + UEBA, whereas one other could supply a SIEM + ASM + XDR. Whereas it’s nice to have extra complete safety merchandise, it’s possible you’ll not want or need the extra modules.
“Not a SIEM” SIEM options add one other layer of confusion, as these merchandise do every thing a SIEM resolution does, however they gained’t present up once you Google “finest SIEM resolution 2024.” One other problem is proving to regulators for compliance functions that though what you employ for SIEM is known as a SOC platform, it’s a SIEM resolution.
So sure, I do assume that including adjectives earlier than the phrase “SIEM” is a futile train that creates extra confusion as an alternative of differentiating a product. However there’s extra.
SIEM and Safety Operations
When evaluating options, it’s essential to resolve whether or not you want a “simply SIEM” or a unified instrument for automating your safety operations heart. I consider that we must always hold SIEM as a standalone time period that predominantly focuses on doing what it says on the tin—info and occasion administration.
SIEM itself might be a part of a wider safety operations platform alongside applied sciences corresponding to XDR, SOAR, UEBA, and ASM. Nonetheless, for a similar causes offered above, we shouldn’t hold calling these converged options “SIEM.”
Because of this, I’ve adjusted the safety operations reviews I’ve been engaged on, specifically the SIEM Radar and autonomous SOC Radar. SIEM focuses on evaluating instruments’ capabilities with respect to info administration. We’re nonetheless together with extra features corresponding to automation and evaluation, however they continue to be targeted on the primary scope quite than branching out to full UEBA or SOAR capabilities.
Autonomous SOC, alternatively, is now a extra standalone method in comparison with its earlier SIEM + SOAR scope. It evaluates the capabilities required by a safety operations heart to handle and automate its each day actions. There may be much less concentrate on compliance and extra on response, orchestration, and consumer monitoring.
