++          <p>
++            Many XWiki instances continue to work well from a user perspective while slowly accumulating security
++            and governance risks. Users can still log in, search, edit pages and access documents, but that does not
++            always mean the instance is properly secured or easy to maintain.
++          </p>
++
++          <p>
++            Security risks are often hidden in less visible areas: outdated versions, inherited permissions,
++            forgotten administrator accounts, overly powerful rights, old extensions, undocumented scripts,
++            weak fallback access or backup assumptions that were never tested.
++          </p>
++
++          <div class="resource-note">
++            <p>
++              <strong>In practice:</strong> an XWiki security review should evaluate the XWiki version,
++              access rights, authentication setup, installed extensions, custom code, infrastructure,
++              backups, restore expectations and the operational practices used to maintain the instance.
++            </p>
++          </div>
++
++          <p>
++            An XWiki security review is a structured assessment of the wiki platform, its configuration,
++            access model, authentication mechanisms, extensions, customizations and operational setup.
++            The goal is to identify risks, maintenance weaknesses and upgrade blockers before they affect
++            users or business-critical content.
++          </p>
++
++          <div class="resource-note">
++            <p>
++              <strong>The main point:</strong> an XWiki security review should not only check whether the application
++              is online. It should evaluate the platform, the access model and the operational practices around it.
++            </p>
++          </div>
++
++          <h2 id="why-it-matters">Why an XWiki security review matters</h2>
++
++          <p>
++            XWiki is often used as an internal knowledge base, intranet, documentation platform or controlled
++            document system. In these cases, the platform may contain sensitive procedures, internal decisions,
++            customer information, technical documentation, compliance records or business-critical workflows.
++          </p>
++
++          <p>
++            The more important the content becomes, the more important it is to understand who can access it, who can
++            change it, which customizations influence it and how safely the instance can be upgraded or restored.
++          </p>
++
++          <p>
++            A security review helps identify risks before they become incidents, upgrade blockers or maintenance
++            surprises. It also gives administrators a clearer view of the current state of the instance.
++          </p>
++
++          <h2 id="what-to-review">What should be reviewed</h2>
++
++          <h3>1. Version and upgrade status</h3>
++          <p>
++            The current XWiki version should be reviewed together with the target upgrade path, installed extensions
++            and infrastructure dependencies. An outdated instance is not only a maintenance concern. It can also mean
++            that security fixes, compatibility improvements and platform hardening are missing.
++          </p>
++
++          <p>
++            The review should also check whether upgrades are performed regularly or only when something breaks.
++            A repeatable upgrade process is part of the security posture of a long-running XWiki instance.
++          </p>
++
++          <p>
++            For more details on upgrade planning, see
++            <a href="$xwiki.getURL('resources.why-upgrade-xwiki')">why regular XWiki upgrades matter</a>.
++          </p>
++
++          <h3>2. Access rights and permission model</h3>
++          <p>
++            XWiki has a powerful access-rights system, but this flexibility needs a clear governance model. A review
++            should check who has administration rights, who has script or programming rights, whether rights are
++            assigned through groups, and whether page-level exceptions are still understandable.
++          </p>
++
++          <p>
++            It is also important to review inherited rights, public areas, restricted spaces, old groups, inactive
++            users and sensitive pages. Many permission problems do not come from one obvious mistake, but from years
++            of small exceptions that nobody reviewed later.
++          </p>
++
++          <h3>3. Authentication and identity management</h3>
++          <p>
++            Authentication should be reviewed beyond the simple question of whether users can log in. LDAP, Active
++            Directory, OIDC, SAML, SSO and MFA setups all need to be checked together with group synchronization,
++            fallback login options, local administrator accounts and recovery procedures.
++          </p>
++
++          <p>
++            SSO is useful, but it does not automatically guarantee a clean access model. Authentication confirms who
++            the user is. Authorization still depends on how XWiki groups and rights are configured.
++          </p>
++
++          <h3>4. Extensions and custom code</h3>
++          <p>
++            Installed extensions, custom applications, Velocity scripts, Groovy scripts, macros, sheets, templates,
++            UI extensions and Java components are all part of the security and maintenance surface of the instance.
++          </p>
++
++          <p>
++            A review should identify what is installed, what is customized, what is still used, what is documented and
++            what needs special validation during upgrades. Custom code should be tracked, explained and tested, not
++            discovered accidentally during an incident or a production upgrade.
++          </p>
++
++          <p>
++            Customizations should also be reviewed from a maintenance perspective. See
++            <a href="$xwiki.getURL('resources.xwiki-custom-development')">how to keep XWiki custom development maintainable across upgrades</a>.
++          </p>
++
++          <h3>5. Configuration, infrastructure and operations</h3>
++          <p>
++            The review should also cover the environment around XWiki: HTTPS and reverse proxy configuration, database
++            access, filesystem and attachment storage, mail configuration, PDF export services, logs, monitoring,
++            server access and separation between production and staging.
++          </p>
++
++          <p>
++            Backups should be reviewed together with restore expectations. A backup strategy is incomplete if nobody
++            knows what is included, how long recovery would take or whether the restore process has ever been tested.
++          </p>

++            <li>Confirm backup coverage, restore expectations and rollback procedures.</li>
++            <li>Document findings and prioritize remediation actions.</li>
++          </ul>
++
++          <h2 id="review-output">What the review should produce</h2>
++
++          <p>
++            A useful security review should not only produce a list of detected problems. It should produce a practical action
++            plan. Each finding should explain the risk, the affected area, the recommended action and the priority.
++          </p>
++
++          <p>
++            Some findings may require immediate action, such as exposed administration rights or unsafe fallback
++            access. Others may become planned improvements, such as cleaning old groups, documenting custom code,
++            reviewing extensions or preparing the next upgrade.
++          </p>
++
++          <div class="resource-note">
++            <p>
++              <strong>A useful review should separate findings by priority:</strong> immediate risks,
++              planned remediation, maintenance improvements and documentation gaps. This makes the result
++              easier to act on instead of producing a generic list of observations.
++            </p>
++          </div>
++
++          <p>
++            The best outcome is a clearer, safer and more maintainable XWiki instance: one where administrators
++            understand the access model, critical features are documented and future upgrades can be planned with
++            fewer surprises.
++          </p>
++
++          <h2 id="when-to-review">When should an XWiki security review be done?</h2>
++
++          <p>
++            A review is especially useful before a major upgrade, after years of organic growth, after an authentication
++            change, before exposing the instance more broadly, after a migration, or when the wiki becomes more
++            business-critical than it was when first installed.
++          </p>
++
++          <p>
++            It is also useful when administration responsibilities change. A new team should not have to guess how
++            permissions, extensions, customizations and recovery procedures were configured years earlier.
++          </p>
++
++          <h2 id="security-review-faq">XWiki security review FAQ</h2>
++
++          <h3>What should an XWiki security review include?</h3>
++          <p>
++            An XWiki security review should include the installed XWiki version, upgrade path,
++            access rights, groups, authentication setup, installed extensions, custom code,
++            infrastructure, backups, restore expectations and operational procedures.
++          </p>
++
++          <h3>Is an updated XWiki instance automatically secure?</h3>
++          <p>
++            No. Updating XWiki is important, but security also depends on permissions,
++            authentication, extensions, custom code, infrastructure configuration, backups
++            and how the instance is maintained.
++          </p>
++
++          <h3>Does SSO solve XWiki access control?</h3>
++          <p>
++            No. SSO helps authenticate users, but access control still depends on XWiki groups,
++            inherited permissions, page-level rights and administrative privileges.
++          </p>
++
++          <h3>Why should custom code be reviewed?</h3>
++          <p>
++            Custom scripts, templates, macros, UI extensions and Java components can affect
++            permissions, workflows, rendering, integrations and upgrade behavior. They should
++            be identified, documented and tested.
++          </p>
++
++          <h3>When should an XWiki security review be done?</h3>
++          <p>
++            A review is useful before a major upgrade, after years of organic growth, after
++            authentication changes, before exposing the wiki more broadly, or when the instance
++            becomes business-critical.
