There’s a seemingly unending quest to seek out the appropriate security instruments that provide the appropriate capabilities on your group.
SOC groups are likely to spend a few third of their day on occasions that do not pose any menace to their group, and this has accelerated the adoption of automated options to take the place of (or increase) inefficient and cumbersome SIEMs.
With an estimated 80% of those threats being frequent throughout most organizations, at present’s SOCs are capable of confidently depend on automation to cowl this massive proportion of menace alerts.
However, whereas it’s true that automation can drastically enhance the effectivity and effectiveness of security groups, it would by no means be capable of cowl all detection and response use circumstances infallibly.
Within the lately launched GigaOm Radar for Autonomous Safety Operations Heart (SOC), they precisely state that “the SOC won’t—and mustn’t—be absolutely autonomous.”
As extra distributors try to problem the dominant gamers within the SIEM class, demand is growing for options that provide automation, which may cowl 80%, whereas additionally providing customization capabilities to cowl bespoke use circumstances – the remaining 20%.

THE 80%: AUTOMATION
With the continuous surge in international knowledge creation, organizations are inevitably seeing an uptick within the variety of alerts managed by security groups.
This may increasingly appear daunting for overworked security groups, however superior vendor choices are implementing automation throughout varied levels of the SOC workflow, serving to groups improve their pace and effectiveness.
The 4 key phases the place we’re seeing automation are:
- Data Ingestion and Normalization: Automating knowledge ingestion and normalization permits groups to course of huge quantities of knowledge from various sources effectively, establishing a sturdy basis for subsequent automated processes.
- Detection: Transferring the duty of making a good portion of detection guidelines permits security analysts to focus on threats distinctive to their group or market section.
- Investigation: Automation can alleviate the burden of guide and repetitive duties, expediting investigation and triage processes.
- Response: Computerized responses to identified and found threats facilitate swift and correct mitigation. This will embody connectivity to case administration, SOAR options, ITSM, and so forth.
Fashionable SIEM alternative distributors, comparable to Hunters, leverage pre-built detection guidelines, combine menace intelligence feeds, and routinely enrich and cross-correlate leads. These automated processes alleviate giant quantities of tedious workloads, empowering security groups to simply handle the big majority of alerts.

THE 20%: CUSTOMIZATION
Though automating the above phases of the workflow have been huge in boosting efficiencies for a lot of SOCs, there’ll at all times stay the necessity for a sure diploma of customization.
Every group has bespoke wants and necessities relying on industry- or company-specific use circumstances. Because of this even when automated and built-in capabilities can handle 80% of the overall use circumstances and duties, extra capabilities are wanted to cowl the remaining 20%.
“Customization” can imply loads of various things, however the primary requirement for security groups is that they’ve each the flexibleness to cowl distinctive use circumstances and the flexibility to scale their capabilities. Let’s take a look at just a few examples of use circumstances the place this may be helpful:
- Ingesting customized knowledge sources: every group has a number of knowledge sources they ingest with totally different log codecs. Many distributors might not have pre-built integrations to ingest from each single knowledge supply, so if a vendor does provide that functionality, it may be an enormous elevate. That is particularly for organizations which can be at present using (or will quickly be transferring to) knowledge lakes to keep up knowledge for a number of functions.
- Detection-as-code: this has change into an enormous buzzword within the security {industry}, however with good purpose. Detection-as-code provides quite a lot of benefits for detection engineers, like improved and environment friendly growth lifecycle, and for giant organizations to extra successfully handle multi-tenancy environments. Should you aren’t aware of the idea, detection-as-code makes use of APIs and deployment pipelines to offer desired auditing capabilities, making the event lifecycle for security operations a lot nearer to that of conventional software program growth. This strategy improves processes to assist groups develop higher-quality alerts or reuse code inside your group so you do not have to construct each new detector from scratch. It additionally helps push detection engineering left within the growth lifecycle, eradicating the necessity to manually take a look at and deploy detectors.
- Scalable enterprise context: Whether or not it’s entities with particular sensitivity ranges (like crown jewels), knowledge from totally different enterprise items or totally different geographies, or siloed knowledge from totally different sources, it takes loads of effort and time to piece collectively data in a means that is comprehensible and actionable. Leveraging an SIEM different that provides you the flexibility to handle all this by way of API brings expanded efficiencies and scalability that not each vendor supplies.
Conclusion
Constructing out an efficient SOC has at all times been, and can proceed to be, a nuanced effort.
There isn’t any one-size-fits-all answer relating to security instruments. It is very important provide methods for organizations to not simply customise for his or her use circumstances, however it’s critical that they’re able to mix this “customization” with the already present automated capabilities that distributors provide.
It has change into a necessity to search for distributors that may provide each a hands-on strategy to customizing instruments, however to take action in a option to bolster the autonomous parts of their choices.
SIEM alternative distributors like Hunters, which have been named leaders in GigaOm’s beforehand talked about report on autonomous SOC, are identified for his or her easy-to-use and pre-built capabilities. And, to make sure that they serve the wants of security groups, are persevering with so as to add revolutionary customization options that permit organizations to tailor their security technique to their distinctive necessities.
Protecting the 80% is significant, however addressing the remaining 20% will set your security crew above the remainder.
