Multi-tenant RAG architectures often fail at one point: retrieval isolation. Teams enforce auth on the API layer but forget that nearest-neighbor search can still surface embeddings from another te...

Data poisoning in RAG is usually subtle. Attackers do not need to corrupt all documents; they only need to influence the chunks most likely to be retrieved for sensitive prompts. That means ingest...

RAG systems are often secured like search features, but they behave like decision engines. Retrieved content can influence model behavior, tool execution, and what data is returned to the user. A ...

Webhook triggers are usually the first attack surface in n8n deployments. They are public, easy to discover, and often connected to high-impact automations such as user provisioning or case closure...

n8n is great for security automation, but it quickly becomes a credential concentration point. API keys for SIEM, EDR, ticketing, and LLM providers often end up in one workflow runner. If that runn...

Good security metrics create clarity and drive action. Bad metrics create noise, blame, and workarounds. The goal is to measure outcomes that engineering teams can influence, then use those signals...

Auditd provides reliable, tamper-resistant logging for sensitive system activity. A focused ruleset can highlight privilege escalation attempts without flooding your logs. This post covers a minim...

Secrets in repos are a reliability problem and a security risk. A simple secrets manager plus a minimal CI integration eliminates most of the pain without adding heavy process. This post shows a s...

Email spoofing is still one of the easiest ways to bypass defenses. SPF, DKIM, and DMARC are the baseline controls that let receivers verify who is allowed to send mail on behalf of your domain. Th...

A scanner run is not a vulnerability management program. The difference is cadence, prioritization, and verification. Even in a home lab, a light but consistent workflow keeps systems patched, redu...
