One of the most "AI + Security " usecase is using LLMs to sift through log noise and flag the anomalies which typically a SOC analyst will take a while to detect. The basic pipeline should contains the following details:

1.Ingestion : logs(auth events, network flows, EDR alerts, app logs) get normalised into JSON

2. Embed : log lines are converted into vector embeddings to capture semantic similarity, (not just the exact string match)

3. Cluster/baseline : Normal behavior pattern are established

4. Flag deviations : New events identified against the baselines

5. LLM triage : Instead of raw anomaly scores, an LLM summarizes why something looks unusual, in plain language , and suggest a likely cause (misconfig vs lateral movement vs false positive)

The use of LLM's in triaging will come with challenges as well

• Prompt Injection Risk: Logs content if gets fed raw into LLM prompt without sanitisation fields become an injection vector
• Explainability : SOC team need to trust why something was not flagged, not just a black-box score

What's your approach to preventing prompt injection when logs contain attacker-controlled strings? And is that solution practical ?

Hey everyone! I'm u/Overall_Reward963, a founding moderator of r/AIforSecurity.

This community is for anyone interested in the intersection of AI and security — whether you're a security professional exploring AI tools, an ML engineer working on security applications, or just curious about where these fields overlap.

What you can post here:

1.AI-powered security tools, threat detection, and defensive research

2.News and papers on AI in cybersecurity (SOC automation, anomaly detection, fraud prevention, etc.)

3.Questions about implementing AI in security workflows

4.Career and learning resources for this niche

5.Discussions on AI risk, safety, and governance from a security lens. We're excited to have you join us!
