OJS Security Hardening & Incident Recovery
OJS security and recovery covers hardening a journal against common vulnerabilities and responding when an installation has already been compromised — malware removal, access review, and restoring a clean, working state from backup where necessary.
Who This Is For
- Journals that suspect or have confirmed a security compromise
- Publishers who've never had a security review of their OJS installation
- Journals running an outdated, unsupported OJS version with known vulnerabilities
- Institutions needing a security review before an audit or compliance requirement
Common Problems This Solves
- An installation showing signs of compromise: unexpected admin accounts, defaced pages, spam content injected into articles
- A journal that has never had file permissions, plugin sources, or admin access reviewed
- Running an unsupported OJS version that no longer receives security patches
- No incident response plan if something does go wrong
What's Included
How the Process Works
Initial assessment
We determine whether this is a preventive hardening review or an active incident, and act accordingly.
Containment (if active incident)
For a confirmed compromise, we isolate the affected environment to limit further damage.
Investigation
We identify how access was gained and what was affected — file changes, database entries, admin accounts.
Cleanup or restoration
The installation is cleaned in place or restored from a known-clean backup, whichever is safer.
Hardening & handover
We apply hardening measures and provide a written summary of what happened and what changed.
Access & Requirements
- Full admin and server/hosting access for the duration of the engagement
- Access to existing backups, if available
- A point of contact who can make time-sensitive decisions during an active incident
Realistic Benefits
- A clear, investigated understanding of what happened rather than a guess
- An installation restored to a clean, working state rather than a partial patch
- Hardening that reduces the chance of a repeat incident
Limitations & Exclusions
- We can't guarantee prevention of all future compromise — no security measure offers 100% protection
- If no clean backup exists, some content or data loss may be unavoidable during recovery
- Criminal investigation or legal reporting of a breach is outside our scope; we'll advise you to involve the appropriate authorities where relevant
Documented, Not Improvised
Every engagement follows a written scope, a staging environment before production changes, and a validation checklist before anything is marked complete. Project write-ups are published as case studies once a client approves sharing them.

Preventive security reviews are scoped as a fixed-price audit. Active incident response is scoped urgently once the situation is assessed.
