ZEISMO Security – Firewall, Malware Scanner & Login Protection

Beskrivning

ZEISMO Security combines a WordPress firewall, malware scanner, login protection and practical hardening in one local security console.

The plugin starts in monitor mode. It inspects suspicious request patterns and records evidence without blocking visitors. After reviewing the activity on your own site, you can enable blocking by attack category.

Included controls

• Request monitoring for SQL injection, cross-site scripting, path traversal, local and remote file inclusion, command injection and scanner patterns.
• A weighted risk score with monitor and block modes.
• Local file-integrity comparisons for supported files in core directories, plugins and themes.
• Local malware pattern scanning with bounded file coverage and scan-limit notices.
• Login attempt limiting and failed-login history.
• Temporary and permanent IP bans plus an allowlist.
• Optional XML-RPC blocking, neutral login errors, REST user-enumeration protection and reduced version exposure.
• Optional browser security headers and WordPress file-editor hardening.
• Local threat history, activity summaries and critical-event email alerts.
• A measured configuration score and WordPress toolbar status.

WordPress malware scanning and file integrity

Run a local scan to review suspicious PHP, JavaScript, iframe, redirect and spam patterns in supported files. Integrity checks compare file hashes with a locally recorded baseline to identify additions, modifications and removals. They do not compare every file against an official clean-copy database. Review the site before accepting a new baseline.

Scans cover supported readable files in wp-admin, wp-includes, the plugins directory and the active theme root. Uploads, the database and root-level files are outside these scan roots. Files over 2 MB, unsupported extensions and symbolic links are excluded. A result with no findings is not proof that the entire website is clean.

A safer first-run flow

New installations begin in monitor mode so administrators can inspect real activity before deciding which categories to block. Review the measured local activity and scan coverage before changing settings.

Local by design

The WordPress.org edition runs its available security controls on your own WordPress site. No account, licence token or remote ZEISMO service is required. Local features in this edition are not restricted by a paid plan.

Blocking is disabled by default. Logged-in editors are excluded from firewall enforcement, and the request filter fails open if it cannot evaluate a request. No security plugin can guarantee that a site will not be compromised.

Privacy and data handling

This WordPress.org distribution performs its security analysis on the WordPress site where it is installed. It does not contact ZEISMO, load remote code, check a ZEISMO licence, send source files to ZEISMO or include a separate updater.

The plugin stores security settings and local security records in the site’s WordPress database. Records can include request paths, browser user-agent strings, usernames used in login attempts, pseudonymous IP hashes and, when enabled, raw IP addresses. Raw IP storage is enabled by default so administrators can investigate and block attacks. Administrators can disable raw IP storage or anonymise logged addresses in Settings.

Security events follow the retention period selected by the administrator. Raw event IP addresses are removed after 90 days even when a longer event-retention period is selected. Optional critical alerts are sent with the site’s configured WordPress mail system and are disabled by default.

Deactivation feedback is optional, stays in the site’s WordPress database and is not sent to ZEISMO. Deactivating or deleting the plugin preserves settings and security records so an administrator does not lose incident evidence. Site owners who want to remove that data can delete the zeismo_security_settings, zeismo_sec_db_version, zeismo_sec_setup_complete and zeismo_sec_deactivation_feedback options and the database tables whose names begin with their WordPress table prefix followed by zeismo_sec_.

Development and source code

All PHP, JavaScript and CSS source is included in this plugin package. The
files in admin/js/ and admin/css/ are the actual readable source used by
WordPress, including admin/js/deactivation.js, admin/css/deactivation.css
and admin/css/toolbar.css. No compilation, minification, npm, Composer or
other build step is required. Edit the bundled source files directly and
test on a development WordPress installation before distributing changes.
This package does not bundle compressed third-party JavaScript libraries.

Request inspection limits

Request-field inspection is capped at eight nested array levels, 256 visited entries across GET and POST, 4,000 bytes per value and 65,536 combined field-name/value bytes. Field names longer than 128 bytes or combined paths longer than 256 bytes are skipped. The request URI has a separate 8,192-byte cap. Sensitive fields are excluded. Inputs beyond these inspection budgets are not examined; reaching a limit does not reject the request. These limits bound plugin inspection work, not PHP request parsing or all denial-of-service traffic.
