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.
  • Temporary passwords for staff setup.

Login Restrictions:
  • Two-factor authentication via IP address approval.
  • IP address banning, including wildcard banning.
  • 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 Why are my searches slow, and how can I improve search speed?
Answer Slow searches can occur when dealing with large amounts of content. Here are some workarounds and solutions:
  • MySQL timeout setting: For MySQL 5.7+, set a query timeout to prevent searches from locking up your database. Composr automatically sets this, but you can configure it manually if needed.
  • Use InnoDB tables: Switching to InnoDB tables in MySQL can prevent slow queries from affecting other users on your website. Note that InnoDB is not officially supported by Composr yet.
  • Enable the fast custom index: As mentioned earlier, the fast custom index is optimized for handling large datasets and filtered searches, potentially leading to significant speed improvements.
Question How does the search engine handle different languages?
Answer Composr's fast custom index supports multiple languages. Content is indexed based on its translated version, ensuring that you get relevant results even when searching in a different language.
Question What are quoted phrases and how do they work?
Answer Quoted phrases allow you to search for an exact sequence of words. For example, searching for "red apple" will only return results containing that exact phrase. Keep in mind that enabling quoted phrases can increase disk space usage.
Question How do stop words affect search results?
Answer Stop words are common words (like "the", "a", "is") that are ignored by the search engine because they add noise and don't contribute to the meaning of the search query. You can customize the list of stop words for the fast custom index. See the search tutorial for more information.

Question What is the Composr Member System?
Answer The Composr Member System is the system used by the Conversr forum software to manage user accounts and information. This includes usernames, passwords, profile information, and usergroups. It also handles user registration, login, and account management. For websites not using Conversr, the member system of the third-party forum software would be used.
Question Can I Use Composr Galleries to Publish Podcasts?
Answer Yes, Composr supports creating podcasts from galleries. The podcast URL follows this format: http://yourbaseurl/backend.php?mode=galleries&select=galleryname&type=rss&itunes=1. Replace yourbaseurl and galleryname accordingly. This URL can be used to subscribe to the podcast in iTunes or other podcast applications.
Question How Do Gallery Slide-shows Work?
Answer When viewing an image or video in a gallery, visitors can initiate a slide-show that automatically cycles through subsequent entries. The slide-show can be paused with a click or keypress. The default slide-show speed can be adjusted by modifying the GALLERY_ENTRY_SCREEN.tpl template.
Question What are Watermarks and How Do They Work?
Answer Watermarks are semi-transparent images overlaid on gallery images to mark their origin or deter unauthorized use. When you add or edit a gallery, you can choose to apply watermarks to the corners of images. Watermarking applies permanently to the uploaded image. Composr uses a reverse tree structure for watermarks: if a sub-gallery doesn't have a watermark defined, it inherits the watermark from its parent gallery.
Question Can Members Create Their Own Personal Galleries?
Answer Yes, members with the "have personal galleries" permission can create their own galleries. These personal galleries are displayed under designated "Personal category container" galleries. They also show up in a tab on the member's profile. Members can only add content to their own galleries unless they have the "Submit to categories belonging to other members" permission.
Question What are Rep-Images and How Do I Set Them?
Answer Rep-images, short for "representative images," are thumbnails that represent a gallery when it's displayed within a list of galleries. They offer a visual preview of the gallery's contents. You can set a rep-image when adding or editing a gallery, or when adding an image to a gallery.
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.
