BSD Distributions & High-Security/Storage Networking
OpenBSD for Enterprise Firewalls
OpenBSD ships PF, a clean packet filter, alongside CARP for failover and pledge/unveil for application confinement. The result is a small, auditable perimeter device with a strong security record. The trade-off is throughput on high-end hardware and a smaller pool of commercial support options.
Ključne točke
- Design rules around explicit default-deny policies and review them as code.
- Use tables and macros so rule sets stay readable as they grow.
- Pair two devices with CARP and pfsync, and test failover under real traffic.
- Apply pledge and unveil to any local daemon you write or modify.
- Keep the base system patched and minimize installed packages on the perimeter.
- Benchmark forwarding throughput with your actual rule complexity before sizing hardware.
- Enable logging selectively and ship logs off-box to preserve evidence.
- Document the change process, since a bad rule can isolate the network instantly.
Pogosta vprašanja
Is OpenBSD fast enough for 10G links?
Often yes with suitable NICs and simple rule sets, but test with your own traffic profile.
Does CARP replace dynamic routing?
No. CARP provides redundancy; routing protocols handle path selection.
Why not use Linux with nftables?
Both work. OpenBSD appeals to teams that value a small, security-focused base and PF's syntax.
How do I update rules safely?
Stage changes, validate syntax, and keep an out-of-band console path.
