The first day on a SOC seat
The day is a queue, one alert you actually finish, the questions you ask before you send it on, and the note you leave. It is not a tour of every dashboard.
The queue
Take the alert the queue gives you, unless the procedure names a different order. Write its title down before you open the next one. A queue you only look at is still a queue.
You are not trying to empty it. You are trying to finish the one in front of you so the next person can trust the note.
One alert you finish
Read the title, the user or the host, the time, what the rule was written to catch, and what ordinary work would look the same. If one of those is missing, the alert is not finished.
The Sigma lab is a rule you build and then watch miss the boring events. The log lab is one question asked of a sample. The detection workbench is the longer set of lessons behind both. Use them so the words in the alert mean something you can point at.
What you ask before you escalate
Ask whether it is still happening, and what has already been changed. On a first day the honest answer is often that you changed nothing. Say that. Do not escalate a title with a blank where the host should be.
If you cannot name a false positive, ask someone who has seen the rule fire on a backup or an admin tool. Escalating “this looks bad” hands the next person your uncertainty, not an alert.
What you write down
The finding is one sentence on what the alert claimed, who or what it named, and what you would change: tune the rule, or send it on with the fields filled in. The handoff is that sentence plus the path to the evidence, the time, and what you already did.
The SOC path on the careers page is the longer list of lessons. This page is the shape of the day. Finish one alert before you open the rest of the list.
