Question How does Composr handle user authentication with external systems like LDAP or HTTP authentication?
Answer Composr can integrate with LDAP and HTTP authentication, but these features are considered complex and may require programming experience to set up correctly. Both methods allow users to log in to Composr using their existing credentials from the external system, streamlining access and management.
Question What are the limitations of using a third-party forum driver?
Answer Using a third-party forum driver can lead to limitations. Custom profile fields of type LONG_TEXT are limited to TEXT length, cookie integration is not officially supported and can be complex, and some forum drivers have specific quirks detailed in the nuances tutorial.
Question What are the implications of using the "none-forum" driver?
Answer Using the "none-forum" driver disables or limits many Composr features, including commenting, points, and user interactions. Consider using Conversr instead and restricting access to the forum zone, join module, and personal zone.
Question How can I integrate my forum visually into my website?
Answer Composr allows you to integrate your forum visually into your website. Enable "Show forum within website" in the Admin Zone configuration module and update the forum link in your menu to pass through the "forums" embedding module. You may need to adjust CSS to achieve a seamless look.
Question How do I set up the forum base URL correctly?
Answer The forum base URL should be a URL prefix to your forums without a script name. For example, http://forums.example.com is correct, while http://forums.example.com/index.php is incorrect. You can fix this using the config_editor.php script and then clear the Comcode page cache.
Question How do comment topics work?
Answer Most Composr resources with commenting enabled create comment topics in the configured comment forum. If the forum uses BBCode, Comcode features not supported by BBCode may not display correctly. Moderate comments from the forum as you would any other topic.
Question Can I switch forums after installing Composr?
Answer It's not easy to switch forums after installing Composr. The member and usergroup IDs referenced by Composr would lose their association. Check the "Importing data into Composr" tutorial for more information on this.
Question What is Conversr and why is it recommended?
Answer Conversr is Composr's built-in forum system. It offers seamless integration, allowing you to use Comcode for forum posts, a unified Admin Zone, shared themes and templates, and innovative features like Private Topics and in-post whispers. Using a third-party forum can be clunky and may lead to maintenance headaches.
Question What forum drivers does Composr support?
Answer Composr supports several forum drivers, including Invision Board, phpBB, myBB, vBulletin, Burning Board, and Simple Machine Forum. If your forum is not listed, professional developers can add support. Composr also provides converters for migrating from these forums to its own forum system, Conversr.
Question What are the web server requirements for running Composr?
Answer Composr is compatible with Apache and IIS servers.

For Apache:
  • Enable mod_rewrite for URL Schemes or URL Redirects.
  • Ensure AllowOverride All or at least AllowOverride Options FileInfo Limit is set in the server configuration.
  • Recommended modules for optimal performance include mod_headers, mod_setenvif, mod_env, mod_deflate, and mod_filter.

For IIS:
  • Don't disable default Feature Delegation for settings changed in the bundled web.config file.
  • Install the URL Rewrite module, essential for URL Schemes, URL Redirects, and basic security.
  • Configure IIS for additional mime-types if needed, as it doesn't serve unrecognized file types by default.

Question What defines a staff member in Composr?
Answer There are two ways to define "staff" in Composr:
  • System-defined staff: This includes administrators and super moderators who have specific privileges within the forum/member system (Conversr).
  • Privilege-based staff: Anyone granted the necessary permissions for a particular situation is considered staff for that context.

Composr prioritizes flexibility by utilizing privileges over fixed roles, allowing for customized staff responsibilities. However, certain features like "staff reply" in tickets inherently rely on a pre-existing understanding of "staff."
Question What steps should I take if my website has been hacked?
Answer If you suspect a security breach, take immediate action:
  • Identify the Cause: Analyze access logs for suspicious activity and pinpoint the vulnerability.
  • Clean and Restore: Restore your website from a clean backup and thoroughly remove any malicious code.
  • Address Vulnerabilities: Patch security holes, update software, and strengthen security configurations.
  • Seek Expert Help: If needed, consult security professionals for assistance with cleanup and prevention.
Question What additional security measures can I implement for my Composr website?
Answer
  • SSL: Enable HTTPS for encrypted communication and improved user trust.
  • Secure Zones: Configure sensitive zones to require confirmed sessions.
  • Restrict Logins: Enforce IP address confirmation for enhanced account security.
  • Maintenance Scripts: Restrict access to maintenance scripts like upgrader.php via IP restrictions.
  • Server Hardening: Disable unnecessary services, change default ports, enable automatic updates, and more.
  • Robots.txt: Use the robots.txt file to prevent search engine indexing of sensitive areas.
Question How does Content Security Policy (CSP) contribute to Composr security?
Answer CSP adds a layer of protection by controlling the resources the browser is allowed to load. It helps prevent:
  • XSS Attacks: By restricting inline scripts and limiting script sources.
  • Data Injection Attacks: By controlling the allowed origins for data requests.
  • Clickjacking: By specifying allowed framing sources.

Composr's CSP implementation utilizes "Trusted partner sites" and nonces for fine-grained control.
Question What is the purpose of "confirmed" and "non-confirmed" sessions?
Answer Composr distinguishes between confirmed and non-confirmed sessions for added security:
  • Confirmed: When you actively log in with your credentials.
  • Non-confirmed: When you return to the site and are automatically logged in via cookies.

You can configure zones to require confirmed sessions, preventing access from cookie-based logins alone. The Admin Zone uses this by default.
Question How can I enhance the security of my Composr installation on shared hosting?
Answer Shared hosting environments can be inherently less secure. Here are some tips:
  • Choose a Secure Host: Opt for hosts that offer suEXEC and open_basedir for better account isolation.
  • Test Security: Verify the host's security measures with the provided filesystem_browser.php script.
  • Restrict _config.php: Remove world-writable permissions from _config.php after installation.
Question How does Composr protect against Cross-Site Scripting (XSS) attacks?
Answer Composr utilizes multiple layers of defense against XSS attacks:
  • HTML Filtering: Configurable levels of filtering prevent malicious script injection.
  • Content Security Policy (CSP): Restricts the sources from which scripts and other resources can be loaded.
  • Input Sanitization: Data is sanitized before being processed to prevent malicious code execution.
  • Output Encoding: Data displayed to users is properly encoded to prevent interpretation as active code.
Question What are the different types of security alerts in Composr?
Answer Composr has a variety of hack-attack codenames that trigger security alerts and logging. Some common examples include:
  • DODGY_GET_HACK: Suspicious URLs with potentially harmful characters.
  • EVIL_POSTED_FORM_HACK: Possible CSRF attempts via malicious form submissions.
  • SCRIPT_UPLOAD_HACK: Attempts to upload PHP scripts, potentially malicious.
  • DOWNLOAD_PRIVATE_URL_HACK/TRY_TO_DOWNLOAD_SCRIPT: Attempts to download sensitive files.
  • BRUTEFORCE_LOGIN_HACK: Repeated failed login attempts.
  • SQL_INJECTION_HACK: Attempts to exploit SQL queries for data extraction.

You can customize alert handling for each type in data_custom/xml_config/advanced_banning.xml (Admin Zone > Security > Configure advanced banning).
Question What are some tips for secure website maintenance?
Answer
  • Avoid FTP: Use secure alternatives like SFTP or SSH for file transfer.
  • Secure Email: Enable SSL for IMAP and POP3 email protocols.
  • Strong Passwords: Use unique and complex passwords for different services.
  • Secure Computers: Keep your own devices patched and secure.
  • Maintenance Password: Remove the maintenance password from _config.php when not in use.
