It’s no secret that the job of SOC groups continues to grow to be more and more troublesome. Increased quantity and class of assaults are plaguing under-resourced groups with false positives and analyst burnout.
However, like many different industries, cybersecurity is now starting to lean on and profit from developments in automation to not solely keep the established order, however to realize higher safety outcomes.
Automation throughout a number of phases of the SOC workflow
The want for automation is evident, and it’s obvious that it’s turning into desk stakes for the trade. Of all cyber resilient organizations, IBM estimates that 62% have deployed automation, AI and machine studying instruments and processes.
Up till now, a lot of those developments in automation have been targeted on response, with SOAR and incident response instruments taking part in an instrumental position in tackling essentially the most pressing section of the SOC workflow.
Centering the main focus solely on response, nonetheless, means we’re treating the signs as an alternative of the foundation reason behind the illness. By breaking down the SOC workflow into phases, it’s simple to see extra situations the place automation can enhance the pace and efficacy of safety groups.
The 4 phases the place it’s attainable to increase protection of automation embody:
- Data ingestion and normalization: Automating knowledge ingestion and normalization can empower groups to deal with large quantities of knowledge from a number of sources, laying the inspiration for added automated processes
- Detection: Offloading the creation of a major proportion of the detection guidelines can unlock time for safety analysts to concentrate on the threats which are distinctive to their group or market phase
- Investigation: Offloading guide and tedious work to shorten investigation and triage processes
- Response: Automatically responding to recognized and found threats for speedy and correct mitigation
Data: Laying the inspiration for automation
Ingesting large quantities of knowledge might sound overwhelming to many safety groups. Historically, groups have had a tough time connecting knowledge sources or have merely needed to ignore the info volumes that they could not deal with on account of cost-prohibitive fashions of legacy instruments that cost for the quantity of knowledge that they retailer.
With the world frequently migrating to the cloud, it’s crucial that safety groups don’t shrink back from large knowledge. Instead, they should enact options that assist them handle it and in flip, obtain higher safety outcomes by having elevated visibility on your complete assault floor.
Security knowledge lakes have introduced with them a paradigm shift in safety operations. They help the ingestion of large volumes and number of knowledge, on the pace of cloud, and permit safety platforms to run analytics on high of them with decreased complexity and at a predictable value.
Detection: Automating the 80%
As extra knowledge is ingested, there’ll inherently be extra alerts found. Again, this may occasionally sound intimidating to overworked safety groups, however automated processes, akin to out-of-the-box detection guidelines throughout assault vectors, is one other excellent instance the place automation can result in an enchancment in protection.
Generally talking, there are a lot of similarities in the way in which networks are attacked, with roughly 80% of risk indicators being frequent throughout most organizations.
A contemporary SOC platform presents out-of-the-box detection guidelines that cowl this 80% by plugging into risk intelligence feeds, open-source information bases, social media, or darkish internet boards, to create logic defending towards the most typical threats. Combining these with further guidelines written by in-house safety groups, platforms are in a position to maintain up-to-date with risk methods and make the most of automated detection round them.
Investigation: Separate the sign from the noise
The investigation section of the SOC workflow is one that’s not usually related to automation. It is historically slowed down by quite a few instruments and guide investigations limiting the effectivity and accuracy of safety groups.
The processes that may be bolstered with automation throughout the investigation section embody:
- Threat-centric clustering of alerts: Security instruments gives you 1000’s of alerts, however in actuality these boil right down to only some threats. At scale, this turns into an unlimited useful resource drain. If the alerts are robotically grouped based mostly on their risk context, then safety analysts can extra simply perceive and reply to single incidents versus chasing tons of of alerts and false-positives.
- Enrichment: By robotically enriching the entities related to every sign or alert with further info from many various knowledge sources, groups get all of the accessible context to know the danger of the alert.
- Correlation: Automatically correlating occasions results in higher visibility into the trail of attackers throughout the group’s community.
- Visualization: Once correlated, assault “tales” will be mapped and visualized in an easy-to-read timeline making it simpler for analysts and different stakeholders to realize clear insights.
Together, these automated duties provide analysts quick indications of which incidents are the best precedence and want additional investigation. This is a drastic enchancment in comparison with legacy methods the place analysts are consistently checking and rechecking incidents, investigating redundancies and manually piecing collectively occasions.
Automated investigation, when together with guide search practices, can result in extra actual incidents investigated, triaged and understood with extra accuracy.
Response: Act rapidly and confidently
Once a risk is recognized, the apparent subsequent step could be to reply to it. As talked about earlier, SOARs do a superb job with automating the response section with recognized threats.
The effectivity of this automation, nonetheless, depends closely on knowledge that’s offered by different sources, i.e. when earlier phases of the SOC workflow can ship usable and dependable outputs that may be despatched to a response software program.
Integrating extra correct knowledge that has been normalized and investigated by expertly engineered automation makes response instruments rather more dependable and efficient.
Obviously, not all responses will be automated as attackers proceed to evolve their strategies. In many situations, it is necessary for analysts to research incidents completely and enact responses manually. But like the opposite phases of the workflow, the extra that these duties will be automated, the extra safety groups will likely be freed as much as tackle extra complicated assaults.
So, why aren’t extra firms utilizing automation?
Many groups know that automation will enhance their productiveness, however altering processes and software program is usually troublesome for a number of causes:
- Replacing legacy software program is time consuming, costly and doubtlessly dangerous
- Getting stakeholder approval for main implementations is difficult and gradual
- Educating analysts on utilizing new software program takes time and sources
- Ever-evolving assault methods maintain safety groups occupied with the “right here and now”
These blockers piled on high of utmost personnel shortages could make the duty appear daunting.
But, as automation continues to take middle stage, the trade will proceed to see important reductions in complete value of possession (TCO), imply time to detection/response (MTTD/MTTR), analyst burnout and CISO frustration.
SOC Platforms to the rescue
When a number of items of the SOC workflow are mixed and automatic, the burden and strain of the conventional workload start to dissolve. Analysts will begin to have the ability to wave goodbye to spending lengthy hours bouncing from device to device, chasing false positives or just sustaining conventional SIEM options.
The new technology of SOC platforms have lots to supply, at each stage of the SOC workflow. Having been born within the cloud, SOC platforms are in a position to make the most of trendy knowledge architectures to extra simply develop further options and enhancements. This, together with the benefit of with the ability to ingest all safety knowledge at a fraction of the price of legacy instruments, has resulted in a development in the direction of elevated automation embedded in them.

An instance of that may be the investigation of threats: that is recognized by most analysts to be a tedious, guide activity, involving sorting via countless false positives. But in the present day’s SOC platforms have launched automation, considerably enhancing the investigation course of. Improvements like automated cross-source correlation, ML fashions, and built-in knowledge interrogation queries have emerged to assist analysts via the repetitive and most laborious risk investigation duties.
Now is the time to start out leveraging automation because it continues to vary the trade. Teams not actively adopting these improvements will discover themselves behind the curve, doubtlessly leaving their organizations weak and their personnel overwhelmed.
