Quick answer

getenforce helps authorized labs sample SELinux mode literacy on hosts they own. Pair with selinux-tips, apparmor-tips, ausearch-tips, auditctl-tips, aureport-tips. Prefer lab VMs — never disable or probe SELinux on foreign hosts without permission.

Tip checklist (authorized only)

  1. Confirm you may run getenforce on the lab host (syllabus box you own or were given access to).
  2. Prefer documenting who / why / ticket before any MAC-mode drill — never change production SELinux mode without change control.
  3. Record short factual notes; quote short Evidence (Enforcing/Permissive/Disabled — never secrets or foreign policy dumps).
  4. Optional: broader SELinux peer → selinux-tips.
  5. Optional: AppArmor peer → apparmor-tips.
  6. Prefer disposable lab VMs for mode drills; quote non-secret mode labels afterward as Evidence.
  7. Prefer read-only getenforce / sestatus for most Evidence binders — refuse unauthorized setenforce 0 / disable cookbooks.
  8. Stop at literacy — no attack or unauthorized MAC-bypass cookbooks.

Allowed framing

  • Classroom labs reviewing getenforce and Enforcing/Permissive/Disabled read-backs on authorized disposable hosts.
  • Binding short factual notes as Evidence (mode label — no secrets).
  • Documenting expected vs observed SELinux mode for authorized inventory notes.
  • Comparing getenforce ↔ selinux / AppArmor / ausearch / aureport peer tip pages under one binder.
  • Testing syllabus-approved permissive-mode labs only when change control authorizes that drill on lab resources.

Scope we will not cover

  • No crack/pirate/keygen via getenforce.
  • No intentional unauthorized SELinux disable against foreign hosts.
  • No secret-theft or policy/AVC credential harvesting against hosts you do not own.
  • No cookbooks that weaken SELinux for attack without authorization.
  • No setenforce 0 framed as an exploit step.

Beginner path (authorized only)

  1. Obtain one syllabus-approved disposable lab host with SELinux tooling available.
  2. Prefer a throwaway lab VM before any mode-change drill.
  3. With authorization, run getenforce; quote the mode label (Enforcing/Permissive/Disabled) as Evidence.
  4. Optional: peer tip pages above when the syllabus asks.
  5. Stop at literacy — no attack or unauthorized disable cookbooks.

Practical notes for authorized labs

  • getenforce reports the current SELinux mode — keep Evidence labels distinct from selinux-tips broader policy drills.
  • Pair with ausearch-tips / aureport-tips when the syllabus zooms on AVC audit follow-up.
  • Policy dumps may embed sensitive contexts — never paste secrets into notes or git.
  • Prefer documenting mode labels the syllabus authorized without dumping full privileged policy JSON.
  • Never commit SELinux policy dumps with secrets to git — even for labs.

FAQ-aligned refusals (quick)

  • Foreign-host SELinux disable / probe → refuse.
  • Unauthorized MAC-bypass / setenforce 0 attack cookbooks → refuse.
  • Attack/credential-theft framing → refuse.
Which to pick
  • Prefer authorized, redacted, secret-free Evidence.
  • Use selinux / AppArmor / ausearch / aureport peer tip pages when the syllabus asks.
  • No crack or unauthorized-access framing.

FAQ

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

A checklist for authorized SELinux mode Evidence (getenforce, Enforcing/Permissive/Disabled read-backs on lab hosts) on hosts you own or were given syllabus access to — not a cookbook for disabling SELinux on foreign servers.

How does this relate to selinux-tips / apparmor-tips / ausearch-tips / aureport-tips?

selinux-tips covers broader SELinux literacy; apparmor-tips covers AppArmor MAC; ausearch-tips and aureport-tips cover audit search/report. This page zooms on a getenforce tip checklist — it does not overwrite those pages.

Can I run getenforce against hosts I do not own?

No. Authorization first. BinBench will not publish unauthorized SELinux mode probes against foreign hosts.

Does this teach attack or SELinux-bypass PoCs via getenforce?

No. Mentions of attack/bypass appear only as refusals. Authorized literacy only — prefer lab VMs and redacted samples. Never teach setenforce 0 as an attack step.

Does this teach secret theft via getenforce?

No. Never paste SELinux policy dumps with secrets, foreign host contexts, or credential-bearing AVC messages into notes. Prefer documenting mode labels (Enforcing/Permissive/Disabled) only.
