Building Aegis: lessons from an AI incident-response agent where memory is a design decision
pranitha95 · reddit · 2026-09-28
A cybersecurity student team shares lessons from building Aegis, an AI agent for account-takeover incident triage that recalls past cases as context. Key takeaways: memory is a design decision, not a switch — they kept detection rules deterministic in application logic while turning past verdicts, analyst actions, notes, corrections, and feedback into the agent's experience. Domain knowledge remains essential: signals like credential-stuffing patterns, MFA fatigue, and repeated IPs are evidence, not conclusions. For trust, the dashboard exposes evidence, timelines, recalled cases and why they were recalled, analyst decisions, and a "What Aegis Learned" section, so behavior changes are never silent.
