Angle

"You don't need to be breached for security debt to hurt your business." This roundup packages medium-severity findings into a relatable security hygiene narrative. The 80/20 list — unglamorous fixes that eliminate most of the risk. No APT theatrics required. Frame as: these are the patterns we find in every SMB audit. Not exotic vulnerabilities — defaults from vendors that never get changed. The lil.business hook: we found all of these in our own infrastructure.

Key Facts to Include

• [DEFENSE] SSH root login not disabled on all systems
  • Issue: One or more syst ems permit root login via SSH. This bypasses sudo audit trails and provides elevated access if credentials are compromised.
  • Fix: Set PermitRootLogin no in /etc/ssh/sshd_config on all systems. Verify with: grep PermitRootLogin /etc/ssh/sshd_config
• [DEFENSE] Fail2ban not configured for all exposed services
  • Issue: Brute-force protection is absent for one or more services accepting authentication. This allows unlimited login attempts.
  • Fix: Install and configure fail2ban for all authentication-accepting services. Verify: systemctl status fail2ban
• [AUTOMATION] CI/CD pipeline lacks secret scanning
  • Issue: Automated pipeline does not scan commits for secrets or credentials. A developer could accidentally commit an API key without detection.
  • Fix: Integrate truffleHog or gitleaks into the CI/CD pipeline. Enable GitHub secret scanning on all repositories.
• [AUTOMATION] Docker images not pinned to digests
  • Issue: Container images are referenced by mutable tags (e.g., :latest) rather than immutable digests. A supply chain compromise could inject malicious code.
  • Fix: Pin all Docker image references to SHA256 digest. Use tools like docker-lock or renovatebot to automate digest pinning.
• [FRAMEWORKS] Essential Eight: Patch Applications not at Maturity Level 1
  • Issue: Application patching cadence does not meet ACSC Essential Eight Maturity Level 1 requirements. Internet-facing applications are not patched within 48 hours of a critical patch release.
  • Fix: Implement automated patch management for all internet-facing applications. Target 48-hour patch window for critical severity. Track compliance monthly.
• [FRAMEWORKS] Essential Eight: Multi-Factor Authentication not fully deployed
  • Issue: MFA is not enforced for all remote access and administrative interfaces. Essential Eight Maturity Level 1 requires MFA for all remote access.
  • Fix: Enable MFA for all remote access (VPN, SSH via Tailscale where possible, admin panels). Prefer hardware tokens or TOTP over SMS.
• [RESPONSE] No centralised log aggregation for security events
  • Issue: Security-relevant logs (auth failures, firewall drops, service errors) are stored locally per-host only. There is no centralised SIEM or log aggregation. Log tampering after compromise would destroy evidence.
  • Fix: Forward all security logs to Wazuh SIEM (already deployed). Verify agent coverage on all hosts. Set minimum 90-day retention.

️ Verify each point above is fully anonymised. No internal hostnames, IPs, or service names. Generalise to "a management interface" not "the admin panel for [specific tool]."

Research Needed

• Industry stats on how often each misconfiguration type appears in real audits (CIS, SANS, DBIR)
• At least one breach story caused by each class of finding
• Free tools SMBs can use to self-check each item
• ACSC/ASD guidance for Australian SMBs
• Build this into a downloadable checklist PDF (CTA asset)
