What makes a SOC analyst stand out
Most of what separates a strong SOC analyst from an average one is habit, not tooling. These are the six habits I look for and try to teach.
1. Understand why the alert fired
Closing an alert is not the same as understanding it. For each one, be able to answer:
- What behavior does this detection look for?
- Which ATT&CK tactic and technique does it map to?
- What would the next step be if this were real?
An encoded PowerShell command is a good example. It could be a management tool or it could be obfuscation. The analyst who decodes it and reads it will know. The analyst who checks whether it has fired before will only know whether it is familiar.
2. Build a personal knowledge base
Keep one place for the things you look up more than once:
- Queries that worked, with a note on what they answered
- Triage steps for the alert types you see most
- Filters and syntax for the tools you use weekly
The format matters less than the habit. Notes compound: the tenth phishing investigation should take a fraction of the time the first one did.
3. Write notes someone else can use
Your notes will be read by a shift lead at handover, by an auditor months later, and occasionally by legal. Write for a reader who was not there.
[Alert]
Brute force: multiple failed logins from 203.0.113.14
[Investigation]
Failed logins against 12 accounts over 4 minutes, all from one external IP
No successful authentication from that IP in the last 30 days
No related activity on the targeted accounts
[Action]
IP blocked at the firewall
No account resets required
[Conclusion]
Unsuccessful password spray. Closed as true positive, no impact.
State what you checked, what you found and what you concluded. If you ruled something out, say so, because otherwise the next reader has to rule it out again.
4. Learn the tools one level deeper
A little depth in three areas pays for itself quickly:
- Regular expressions, for extracting fields from logs that were never parsed properly
- Python, for the triage steps you repeat every day
- PowerShell, for answering questions on a Windows host without waiting for someone else
Reading other people's detection logic is the fastest way to improve your own. The Sigma rule repository is a good place to start: pick a technique you have triaged and see how the rule approaches it.
5. Follow what looks odd
Do not wait for a ticket to look into something strange. If a user opens five hundred documents at 2 AM, or logins fail in the same pattern every weekend, spend twenty minutes on it. Write down what you found either way and tell your lead.
Most of these turn out to be nothing. The ones that are something are how analysts become detection engineers.
6. Communicate with context
When you escalate, lead with what you know, what you do not know yet, and what you are doing about it:
Investigating possible beaconing from host XYZ123.
Outbound to 203.0.113.99 on 443/TCP every 10 minutes since 02:10.
No known business justification. Checking for persistence now, update in 30 minutes.
A message like this lets a senior analyst decide in ten seconds whether to step in.
Be reliable first
Do the basics well and consistently: be on time, close what needs closing, and hand over cleanly. Then start asking how the detections work, why they are tuned the way they are, and what would make the playbook better.
You do not need to be the smartest analyst in the room. Be the one who learns fastest and communicates most clearly.
