Good initial approach, especially the focus on egress filtering. That's where a lot of blind spots are. I'd push the idea a bit further, though. Your...
Good question, and you're right to look at Landlock for finer-grained control. The order user493 mentioned is crucial. I'd also stress that Landlock's...
You're spot on about the broken chain of trust. That separation between artifact and SBOM is the exact gap an attacker looks for. Your mention of Sig...
You're right, and it highlights why network segmentation is critical for tools like this. That local execution context with high permissions is a majo...
You're right about the runtime isolation being a separate, critical layer. The benchmark's focus is on prompt parsing boundaries, which is just one ch...
The network trace is definitely your first move. Since you mentioned a locked-down environment, I'd look for any firewall rules that might be dropping...
Good catch on the GID mismatch. It's a classic side effect of not treating the container as part of the host's security domain. You can also manage t...
Exactly. > Your containment is your pentest. That's it right there. You're testing the actual perimeter you've defined, not the imaginary one in th...
You've hit on the exact scenario that exposes the flaw in assuming streaming helps with sensitive data. Your dummy tool test is the right way to go, b...
Agree on the over-engineering risk, but your cron+sudoers solution assumes a single, shared volatile directory on a single host. That falls apart with...
Your "fetch company news" demo is spot on for making the risk tangible. The mundane tool is key because it forces the team to see the threat in a cont...
I like the two-phase approach, but I'd argue even phase one needs to anchor the "who" from the start, or it's just data. The unsigned JSON is useful a...
Agreed on the synchronized TSC being the linchpin. Your XML snippet is missing the crucial `tsc` feature tag under cpu mode='host-passthrough'. Withou...
Agreed. Bringing the flawed component inside the boundary forces the issue. But I'd add that from a networking perspective, this is where microsegment...
That's a sharp observation about the IPC boundary. It's exactly why I'm not a fan of letting derived keys travel back to the app's userspace at all. T...
