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.
  • 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 do I embed content from other modules into a Comcode page?
Answer You can use various blocks to embed content from different modules:

  • main_content block: Allows you to feature individual entries from modules/content like news or articles.
  • main_multi_content, main_cc_embed, main_gallery_embed, main_news blocks: Enable you to pull in and display multiple entries based on categories or other criteria.
  • main_include_module block: Provides a powerful way to integrate any module screen directly into a Comcode page.
Question What is the difference between blocks and boxes in Composr?
Answer While both terms may seem similar, they have distinct meanings in Composr:
  • Blocks are functional units that generate dynamic content or provide specific features. They don't inherently have a visual form and their output can vary widely.
  • Boxes are a visual design element in Composr, essentially containers that visually group content on a page and often with a title at the top.

In practice, blocks often place their content within a box, but this isn't a requirement / standard.
Question Can I customize the appearance of blocks?
Answer Yes, you can customize the appearance of blocks by editing the associated templates and CSS. Each block typically has a corresponding template file (e.g., BLOCK_MAIN_NEWS.tpl for the main_news block) that controls its HTML structure. You can modify this template to change the layout and styling of the block's output.

An easy way to do this is through the template editor in Admin Zone > Style > Themes, and click edit templates for the relevant theme.
Question How do I add dynamic content to my Comcode pages?
Answer Composr utilizes "blocks" to embed dynamic content and functionality within Comcode pages. These blocks can range from displaying recent forum posts to showing information about the logged-in user.

To add a block, you can use the "block construction assistant" accessible via a button above the editor. This tool provides a user-friendly way to:
  • Browse and select available blocks.
  • Configure the block parameters.
  • Preview the block output.
  • Generate the necessary Comcode to embed the block.
Question How do I create a new Comcode page?
Answer Composr provides two easy ways to create a new Comcode page:

Method 1: Direct URL Entry
Type the desired URL of your new page into your browser's address bar.
Since the page doesn't exist yet, Composr will present you with a 404 error and a link to create it. Click the link to open the Comcode page editor.

Method 2: Admin Zone
Navigate to Admin Zone > Content > Pages (Comcode pages).
Scroll down to the list of existing pages and enter the name of your new page using the ":" (page-link) format. For example, a new page in the Welcome zone named "about" would be entered as ":about", or a new page in the "site" zone named "foobar" would be entered as "site:foobar".
Question What are Comcode pages?
Answer Comcode pages are standalone content pages within the Composr system that you can create and edit using either a WYSIWYG editor, a simple markup language called Comcode, or a combination of both.

Think of them as documents within your website, offering flexibility beyond the structured content provided by modules like forums or news. You can use them to build landing pages, about us sections, contact pages, and more.
Question Can I create custom Comcode tags?
Answer Yes, you can create custom Comcode tags through the Admin Zone > Setup > Custom Comcode. This allows you to add unique functionality or wrap specific HTML code (especially if you use a certain block of HTML frequently on your site) for easier use. Custom Comcode tags can be tailored to your needs and even include your own parameters. You can also specify if the Comcode is dangerous so only those with elevated privileges can use it.
Question What are the security considerations when using Comcode?
Answer Composr has a multi-tiered security system for Comcode. HTML code is filtered based on user permissions to prevent XSS attacks. Content is parsed with different credentials depending on who is editing or adding it, ensuring users can't elevate their privileges by modifying existing content.
Question What is oEmbed and how does it work with Comcode?
Answer oEmbed is a system that allows you to embed content from other websites simply by pasting its URL. When you paste a supported link in Comcode, oEmbed will automatically embed the content for you in a nicely-formatted box. For example, pasting a YouTube video link will embed the video directly into your content so it can be played on your website.
Question How do I add attachments to my content?
Answer Composr has an integrated attachment system. You can upload files, like images or documents, via the attachments section (or the image button if using the WYSIWYG editor with simplified attachments UI), and they will be automatically added to your Comcode using the attachment tag. You can then move this tag within your content to position the attachment as needed.
