ausearch tips — authorized audit search literacy
ausearch helps authorized labs sample audit-event search literacy on hosts they own. Pair with auditctl-tips, journalctl-logs-tips, fail2ban-tips, ufw-tips, ss-tips. Prefer lab VMs — never mine foreign audit logs without permission.

Tip checklist (authorized only)
- Confirm you may inspect ausearch Evidence on the host (lab VM / syllabus box you own or were given access to).
- Prefer short, syllabus-approved searches — never inventory foreign users or hosts.
- Record short factual notes; quote short Evidence (key, type, time window — redact secret argv and usernames).
- Optional: rule listing → auditctl-tips.
- Optional: journal reading → journalctl-logs-tips.
- Optional: jail literacy → fail2ban-tips.
- Redact usernames, secret argv, hostnames, and inventory labels if policy requires.
- Stop at literacy — no exploit / stealth / unauthorized-access cookbooks.
Allowed framing
- Classroom labs searching audit events on authorized hosts.
- Binding short factual notes as Evidence.
- Documenting expected vs observed event keys for authorized inventory notes.
- Comparing ausearch ↔ auditctl peer tip pages under one binder.
Scope we will not cover
- No crack/pirate/keygen via ausearch.
- No intentional stealth / anti-forensics PoCs against foreign hosts.
- No credential-theft via audit event fields against hosts you do not own.
- No unauthorized surveillance of users outside syllabus scope.
Beginner path (authorized only)
- Obtain one syllabus-approved lab host you control or may inspect.
- Run a short ausearch sample; quote success.
- Bind notes as Evidence; redact sensitive fields and labels.
- Optional: compare with auditctl-tips / journalctl-logs-tips / fail2ban-tips.
- Stop at literacy — no attack or surveillance cookbooks.
- Prefer authorized, redacted Evidence.
- Use auditctl / journalctl / fail2ban peer tip pages when the syllabus asks.
- No exploit, stealth, crack, or unauthorized-access framing.
For legal, authorized and educational use only.
FAQ
What is an "ausearch tip" page in BinBench framing?
A checklist for searching authorized audit-event literacy Evidence on hosts you own or were given syllabus access to — not a cookbook for hunting foreign users.
How does this relate to auditctl-tips / journalctl-logs-tips?
Those pages cover rule listing and journal reading. This page zooms on a general ausearch tip checklist — it does not overwrite those pages.
Can I run ausearch on hosts I do not own?
No. Authorization first. BinBench will not publish unauthorized-access recipes.
Does this teach exploit / stealth / bypass PoCs via ausearch?
No. Mentions of exploit/bypass appear only as refusals. Authorized literacy only.
Does this teach credential theft via ausearch?
No. Redact usernames, PIDs tied to secrets, hostnames, and inventory labels before sharing excerpts.
