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.
Question What are the main security features of Composr?
Answer Composr has a robust set of security features to protect your website, including:

Passwords:
  • Visual representation of password quality and enforcement of complexity rules.
  • Password expiry and prevention of re-use.
  • Secure password hashing, even if the database is compromised.

  • Session locking to IP addresses.
  • Configurable session expiry times.
  • Ability to prevent privileged actions from auto-logged in sessions.
  • Optional member approval process.

Auditing Systems:
  • Comprehensive audit logging of administrative actions.
  • Logging of user actions and IP address history.
  • Tools to analyze audit logs.
  • Failed login logging.
  • Hack attack detection, logging, and banning.
  • Email notifications for changes to user credentials.

Framework Security:
  • Protection against CSRF attacks.
  • Click-jacking prevention via CSP implementation.
  • Secure coding standards and scanning techniques.
  • Configurable HTML filtering to prevent XSS attacks.
  • Secure code modularization standards.

Other features:
  • Granular privileges and access permissions.
  • Content submission validation process.
  • Rootkit detection system.
  • Spam prevention systems.
  • Web application firewall rules.
  • Moderation systems.

Question How Do I Import Images in bulk into a Gallery?
Answer You can import images in bulk using a CSV file. The file should be named descriptions.csv and placed in the uploads/galleries directory. The first column should contain filenames (without the path), and the second column should contain descriptions. The filenames should correspond to images also located in the uploads/galleries directory. Composr will automatically match the descriptions to the images during import.
Question What Image and Video Formats are Supported?
Answer Images:
  • .jpg/.jpeg: Highly compressed, best for photos due to minimal noticeable quality loss.
  • .png: Good compression with no quality loss, ideal if bandwidth isn't a concern.
  • .gif: Limited to 256 colors and poor compression. Better alternatives are video or APNG.
Note that Composr does not support SVG because hackers can leverage the XML-like structure of SVG files to compromise a website.

Videos:
  • .mp4 (h.264 aac encoding): The recommended format, widely supported.
  • .mov (h.264 aac encoding): Identical to .mp4.
  • .webm: Supported natively in most browsers, but requires plugins for Internet Explorer/Microsoft Edge and Safari.

Other formats, while they may work, are generally discouraged due to compatibility issues and lack of consistent addon or browser support.
Question What are Composr Galleries?
Answer Composr Galleries are a system for storing, organizing, and displaying images and videos. They function like categories, allowing you to group related media together. Galleries can be structured hierarchically, with sub-galleries nested under parent galleries, similar to a folder system. Each gallery has settings that control its appearance and behavior.
Question How are forums structured in Composr?
Answer Composr forums are organized hierarchically:
  • Forum Groupings: Broad categories that contain forums.
  • Forums: Contain topics related to a specific subject.
  • Sub-forums: Forums nested under other forums, providing further categorization.
  • Topics: Threads of conversation containing a series of posts.
  • Posts: Individual messages within a topic.
Question How do I debug email integration issues?
Answer
  • Email Tracking: Composr marks emails as read when processing posts. Marking an email unread will trigger re-processing.
  • Log File: Create an empty file named data_custom/mail_integration.log to capture detailed log data for troubleshooting.
Question How can I control who can post in my forums?
Answer You can manage posting permissions using Composr's usergroup system.

  • Forum View Access: Determine which usergroups can view each forum.
  • Privilege Overrides: Grant or deny specific privileges (e.g., posting) to usergroups within a forum.
  • Bypass Validation: Allow trusted members to post without moderation (or vice versa, require validation for certain usergroups).
Question What special features does Composr's Conversr offer compared to other forum software?
Answer
  • Advanced Polls: Blind polls, forcing or setting of default options, and point-weighting.
  • Private Topics: More sophisticated than traditional private messages.
  • Forum Introduction Questions: A flexible way to control access and encourage engagement (e.g. forum-specific rules or forum passwords).
  • Cascading Topics: Pinned topics that appear in multiple forums.
  • Integrated Moderation: Streamlined moderation tools within the forum interface.
Question How do topic polls work?
Answer Topic polls are a powerful tool for gauging opinion within discussions. You can:

  • Control Result Visibility: Choose whether results are visible before voting.
  • Require Topic Reply: Force users to reply to the topic before voting.
  • Show Voter Identities: Optionally display which members voted for each option.
  • Allow Vote Revocation: Let voters change their vote while the poll is open.
  • Set Voting Close Time: Define a specific date or time for the poll to close.
  • Restrict Selections: Limit the number of options voters can choose.
  • Allow Guest Voting: Enable voting for unregistered users.
  • Weight Votes by Points: Give more influential members greater voting power (requires the points addon).
Question What are the different types of posts in Composr forums?
Answer
  • Regular Posts: Standard posts made by members within a topic.
  • Quick Replies: Shorter replies made directly from the topic view.
  • Anonymous Posts: Members can choose to post anonymously, appearing as a guest. Staff can track the actual user if needed.
  • Emphasised posts: Posts made by staff (or marked by staff) which are highlighted to draw attention as they are important.
  • Whispers: Private messages embedded within public topics, allowing for side conversations.
  • Private Topic Posts: Private messages sent between specific members (e.g. an on-site "inbox").
Question Can I integrate email with my forums (mailing list)?
Answer Yes, you can enable email integration for each forum individually. This allows members to post and receive updates via email.

Requirements:
  • PHP IMAP extension installed
  • System scheduler (Cron) running
  • IMAP-compatible mail server

Recommended:
  • Mail server enforces SPF and DKIM for email validation
  • Mail server limits email size to prevent abuse
  • System scheduler runs frequently (e.g., every minute) so members get prompt updates
