Modules can add new features to your Backdrop site, or improve the way your existing features currently work.
Redirect 403 to User Login
Redirect the HTTP 403 error page to the Backdrop /user/login page.
Similar Entries
Provides a default View with block display for listing published content that
is similar to the content being viewed.This module uses MySQL's FULLTEXT indexing for MyISAM tables, and should
automatically add the index when you activate the module for the first time.Passphrase policy
Enforce restrictions on user passwords by defining a password policy that encourages the use of pass phrases.
Http:BL
Provides IP-based blacklisting through http:BL and allows linking to a honeypot by using Project Honeypot (http://www.projecthoneypot.org/).
Markdown filter
Provides Markdown filter integration for Backdrop input formats. The
Markdown syntax is designed to co-exist with HTML, so you can set up
input formats with both HTML and Markdown support. It is also meant to
be as human-readable as possible when left as "source".Markdown Extra filter
Don't use this module.
Markdown Extra merged into Markdown.
Previous login
Add a detective security control to Backdrop by displaying the previous login timestamp after a successful login.
robots.txt
Control the contents of your robots.txt file through Backdrop configuration.
Session expire
Deletes user sessions which have been idle longer than a configured time.
On busy sites, the sessions table can grow to be very large, and that can cause slow accesses to it, as well as slow writes due to locking, leading to performance bottlenecks.
Session limit
Limit the number of simultaneous sessions users may have. Limits can be applied by role and per account.
Force users to log out of any extra sessions after they exceed the administrator-defined maximum.
Site verification
Verify ownership of your Backdrop website to search engine services.
Supported vendors are:
Ejector Seat
Use Javascript (ajax) code to check periodically to see if a user is still logged in. If the user is NOT logged in, the current page is reloaded so that the user sees the page as an anonymous user.
Bot repellent
Add the X-Robots-Tag HTTP header to instruct search index bots on permissible activity.
Bad judgement
Trust me. You shouldn't be enabling this module.
But if you do enable this module, you shouldn't be enabling the module that
requires this module either.Paranoia
Impose additional restrictions on the granting of elevated privileges to anonymous and authenticated user roles.
Member for hack
Alter the creation date on a user profile that is used for displaying the "Member for" time period.
Suggested altered creation dates:
Text sitemap
Creates a virtual sitemap.txt file for indexing by search engines.
Disable login errors
Prevent user enumeration by blocking the display of all login error messages. A user attempting to login will not be aware if the account exists, an invalid user name or password has been submitted, or if the account is blocked.
Some of the messages which are hidden include:
Flood control
Add an administration interface for hidden variables that limit login attempts and contact form submissions in Backdrop.
Diskfree
Get a disk utilization report in Backdrop's status report and a cron-triggered e-mail warning when locally mounted disk space on your Backdrop server reaches a preset threshold.
The alert e-mail uses the following template:
Clear Password Field
This Backdrop module clears common password form fields.
X-Originating-IP
Add the X-Originating-IP header to all outgoing Backdrop emails to assist with investigation of the sources for spam and unsolicited bulk email.
Remove Generator
Remove Backdrop's Generator META tag to hinder web application fingerprinting.
