AI In SOC

As AI becomes increasingly utilized throughout the security space, it's important to consider how it should be used most effectively. We've all seen companies adding AI into every offering and function they perform, often as much as possible.

In security operations, this creates a divide between two types of companies:

  1. Companies that rely primarily on AI to do the work
  2. Companies that enable their operators to become higher performers through the use of AI

Both types address a clear problem: volume. Anyone who has worked in a SOC knows that alert volume results in burnout, limits the number of customers you can support, and takes time away from more important tasks. Using AI to accelerate triage of high-volume, lower-complexity alerts is a practical and effective strategy. It frees analysts to focus on the ambiguous cases that require human judgment. With the right context and data, AI can meaningfully assist in distinguishing malicious from benign activity — but "most of the time" isn't good enough when a miss means a breach. AI augments the analyst; it doesn't replace their judgment.

That said, keeping a human in the loop is critical for the fringe cases: AI hallucination, highly complex technical investigations, and even situations where attackers attempt to fool the models with injection or evasion techniques.

Let's talk about some ways you can be the second type of company: the one that enables operators rather than replaces them.



AI for Triage Enhancement

Utilizing AI for enhancement of the triage process is something all security operation centers should be doing right now. While AI may occasionally be wrong or may hallucinate, anyone not taking advantage of it to work across the huge amount of data that SOCs process will fall behind their competitors.

I'm not suggesting that an AI model should be constantly closing alerts. Instead, consider this: Could an AI elevate alerts that would otherwise not have been investigated?

All SOCs process swathes of low-fidelity or low-severity alerts that are usually suppressed, deduplicated, or closed out through automation. What if you could use an AI model to review these alerts that would've been closed anyway and elevate those requiring human response to higher priorities? The worst-case scenario—a false negative—isn't applicable here. These alerts wouldn't have received much attention anyway. In the ideal scenario, you could intelligently review alerts your analysts wouldn't have looked at otherwise, escalating truly concerning activity for a human to look at.

AI for Quality Assurance

Another clear use case for AI in SOCs is quality assurance. Many QA checks on investigations are random, but what if you could curate a set of prompts that tasks AI with looking for common mistakes within your investigations and notifies a human to review them?

The AI could highlight the causes for concern, providing a starting point for the human analyst. It could even offer suggestions to both the reviewer and the analyst, making note of possible improvements. The higher quality the QA prompts, the better the feedback.

AI for Validation

Similar to the first use case mentioned, AI could validate analyst investigations and look for logical gaps or potential blind spots. Effectively, it could be used to provide top cover for analysts, giving them more space to triage quicker without chasing down every lead, knowing that the model (ideally trained on past cases!) is fact-checking and logically validating their investigation, freeing them to confidently triage without second-guessing themselves.

Human Augmentation

While AI excels at handling repetitive high-volume tasks, human expertise remains essential for complex investigations, fringe cases, and maintaining accountability. Rather than viewing AI as a cost-cutting tool to reduce headcount (or to take on many more customers with the same headcount), think of it as an investment that multiplies the effectiveness of your existing team. By strategically deploying AI to handle or fact-check routine work, you free your analysts to focus on the sophisticated threats that truly require human judgment and critical thinking.

If you take one thing from this article, I want it to be this:

Using AI to augment your operators may not show the same immediate "return" as replacing them, but, over time, it will increase your service quality tenfold.

Report As You Go: Maintaining Good Documentation for SOC Analysts

Working in the SOC can be a grind. Whether triaging alerts, escalating to clients, or just trying to understand why users download malicious files, we feel the need to get through tickets as fast as possible. But in that rush, we can actually hinder our progress and slow ourselves down.

What can we do to make tickets, notes, and escalations aid the SOC in the past, present, and future? Using structure, “building upon,” and clear and concise direction, we can set ourselves and the SOC up for success.

Structure

In one of Jason Blanchard’s “Job Hunt Like a Hacker” BHIS livestreams, he emphasized using bullet points when listing job experience rather than a big wall of text, as “people will get lost and stop reading.” I took this advice to heart in the way I structure the internal notes of my tickets.

I use structured, cascading bullet points to document each step taken and each piece of evidence discovered during triage. This format makes it easy for any teammate to pick up where I left off — or for a lead to QA my work without asking me to explain it.

Building Upon

Now that we know how to structure our notes, what should we actually document? While triaging the alert, begin with steps taken. This could be “- Ran query: {the query itself or link to SIEM platform of query used}”, “- Investigated User’s recent login history”, etc. From there, gather evidence (log data, artifacts, screenshots, etc.) pertaining to the events that occurred and add them to your notes as you discover them.

Just because you add something to your notes, doesn’t mean it’s set in silicon (excuse my play on words...). If an event or evidence is not actually linked to the alert, you can remove it. It’s better to capture too much and trim later than to miss something you’ll need to reconstruct hours or days from now. This is a key part of the “Report-As-You-Go” process.

Clear and Concise Direction

We have our structure and our evidence... now what? It’s time to edit down and proofread what we have in the internal so that it only contains necessary information. Clear away any rabbit holes or evidence not pertinent to the alert in question. Your thought process should be apparent from the information you present. A final bullet point stating your verdict will enhance this clarity, such as “- Atypical behavior of user, will escalate and confirm expected.”

With the evidence well-documented and your verdict made, you are set to either update the client or close the ticket, setting everyone up for future success.

Documentation Muscle

Just like regular muscles, you need to constantly work out your reporting-as-you-go muscles. The more you exercise these muscles, the stronger they become. It’s an ever-improving process: the first couple of internals you create are not going to be great, but you will see improvement the more you work at it. Another way to work this muscle is to start a blog and write walkthroughs on different cyber rooms, CTFs, or topics you’re studying. Get started today!

The Life of a SOC Analyst: Responsibilities, Challenges, and Strategies for Success

Security Operations Centers (SOCs) serve as a critical line of defense against today's constantly evolving cybersecurity threats. At the heart of these teams are SOC analysts, who monitor, detect, and respond around the clock to potential attacks.
