Quick answer

restorecon helps authorized labs sample SELinux default file-label restore literacy on hosts they own. Pair with chcon-tips, getenforce-tips, selinux-tips, semodule-tips, runcon-tips. Prefer lab VMs — never relabel foreign hosts without permission.

Tip checklist (authorized only)

  1. Confirm you may run restorecon on the lab host (syllabus box you own or were given access to; typically needs root/CAP for system paths).
  2. Prefer documenting who / why / ticket before any recursive restore — never relabel production trees without change control.
  3. Record short factual notes; quote short Evidence (path pattern + type label — never secrets or foreign inventories).
  4. Optional: manual context peer → chcon-tips.
  5. Optional: mode peer → getenforce-tips.
  6. Prefer disposable lab VMs for restore drills; quote non-secret path/type afterward as Evidence.
  7. Prefer read-only restorecon -n -v dry-run for most Evidence binders — refuse unauthorized hostile-relabel cookbooks.
  8. Stop at literacy — no attack or unauthorized MAC-bypass cookbooks.

Allowed framing

  • Classroom labs reviewing restorecon -n -v dry-run read-backs on authorized disposable hosts.
  • Binding short factual notes as Evidence (path pattern + SELinux type — no secrets).
  • Documenting expected vs observed default contexts for authorized notes.
  • Comparing restorecon ↔ chcon / getenforce / selinux / semodule peer tip pages under one binder.
  • Testing syllabus-approved path restores only when change control authorizes that drill on lab resources.

Scope we will not cover

  • No crack/pirate/keygen via restorecon.
  • No intentional unauthorized SELinux relabel against foreign hosts.
  • No secret-theft or path/credential harvesting against hosts you do not own.
  • No cookbooks that weaken SELinux via hostile relabel for attack without authorization.
  • No restorecon -R framed as an exploit step against production.

Beginner path (authorized only)

  1. Obtain one syllabus-approved disposable lab host with SELinux file-context tooling available.
  2. Prefer a throwaway lab VM before any recursive restore drill.
  3. With authorization, run restorecon -n -v on a lab path; quote selected path/type labels as Evidence.
  4. Optional: peer tip pages above when the syllabus asks.
  5. Stop at literacy — no attack or unauthorized relabel-bypass cookbooks.

Practical notes for authorized labs

  • restorecon restores default SELinux file contexts from policy — keep Evidence labels distinct from chcon-tips manual changes.
  • Pair with getenforce-tips when the syllabus zooms on mode before a restore drill.
  • File lists may embed sensitive paths — never paste secrets into notes or git.
  • Prefer documenting path patterns and type labels the syllabus authorized without dumping full privileged trees.
  • Never commit SELinux file-context dumps with secrets to git — even for labs.

FAQ-aligned refusals (quick)

  • Foreign-host SELinux relabel → refuse.
  • Unauthorized MAC-bypass / hostile-relabel attack cookbooks → refuse.
  • Attack/credential-theft framing → refuse.
Which to pick
  • Prefer authorized, redacted, secret-free Evidence.
  • Use chcon / getenforce / selinux / semodule peer tip pages when the syllabus asks.
  • No crack or unauthorized-access framing.

FAQ

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

A checklist for authorized SELinux default file-context restore Evidence (restorecon -n / -v / path restore on lab hosts) on hosts you own or were given syllabus access to — not a cookbook for relabeling foreign servers.

How does this relate to chcon-tips / getenforce-tips / selinux-tips / semodule-tips?

chcon-tips covers manual context change; getenforce-tips covers mode labels; selinux-tips covers broader SELinux literacy; semodule-tips covers modules. This page zooms on a restorecon tip checklist — it does not overwrite those pages.

Can I run restorecon against hosts I do not own?

No. Authorization first. BinBench will not publish unauthorized SELinux relabel drills against foreign hosts.

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

No. Mentions of attack/bypass appear only as refusals. Authorized literacy only — prefer lab VMs and redacted path/context labels. Never teach hostile relabel as an attack step.

Does this teach secret theft via restorecon?

No. Never paste SELinux context dumps with secrets, foreign host path inventories, or credential-bearing file lists into notes. Prefer documenting path patterns and type labels only.
