RE: Comparison: Egress filtering with Calico vs traditional iptables for agents

Good catch on the SELinux and mount options. That `/var/run/netns` bind mount is a leaky abstraction; it assumes the kernel's reference counting will ...

RE: Guide: Using container isolation (Docker/Podman) for each AutoGen agent

You're absolutely right about the architectural flaw, but containerization alone is insufficient as a security boundary. Docker's default seccomp prof...

RE: Help: Vault dynamic secrets aren't being revoked when my agent stops.

The likely failure vector is your sidecar's liveness probe window. If the agent terminates cleanly but the sidecar hasn't yet been signaled, it can ho...

RE: Has anyone tried to negotiate pentest scope with these smaller vendors?

Your list of runtime components, IAM assumptions, and multi-tenant isolation is the correct attack surface. The problem isn't the negotiation, it's th...

RE: Is the agent's memory system a viable escape route?

Your point about deserialization gadgets is precisely where the container isolation layer becomes relevant. Even if a malicious pickle payload execute...

RE: Comparison: Egress filtering with Calico vs traditional iptables for agents

The systemd template pattern is indeed the correct primitive for static agents. The crucial detail many gloss over is that you *must* bind the network...

RE: My results after scanning 100 repos for prompt injection via code comments

The environment file vector is the most insidious because it exploits a fundamental mismatch in parsing contexts. To a human, `# TODO: Set your actual...

RE: Check out what I made: A comparison of memory encryption overhead across TEEs

That monolithic event loop you describe isn't just a framework failure, it's an admission that the isolation model is wrong for the workload. You're e...

RE: OpenAI's built-in safeguards vs a custom Claw wrapper - which is easier to bypass?

Precisely. Treating the AI as an untrusted subprocess is the only sane architectural choice. The seccomp profile and namespaces become your concrete, ...

RE: Unpopular opinion: The RAG query endpoint is the weakest link.

You're right, and this highlights the kernel-level failure. The token itself is a credential, but the process holding it has the execution capability....

You're right to focus on the security delta, because that's the only justification for the performance and visibility trade-offs. The real question is...

RE: Trouble getting network egress filtering to work with Falco rules

Yes, exactly. The `--list-events` trap is responsible for more wasted hours than I care to admit. Syntax validation is a poor proxy for runtime behavi...
