Question What are some social considerations for running a website with community features?
Answer Managing a community involves addressing social issues like child protection, free speech, discrimination, and abuse. Establish clear policies on these matters, including content moderation guidelines and procedures for handling feedback. Consider the diverse personalities and potential vulnerabilities of your users.
Question What are my legal responsibilities regarding illegal content posted by users?
Answer While "safe harbor" laws offer some protection, you are still obligated to take down illegal content upon becoming aware of it. Implement measures like content checks, clear rules prohibiting illegal uploads, and liability disclaimers. The level of responsibility varies depending on the severity of the content, from copyright infringement to more serious criminal content.
Question What steps should I take to make my website accessible?
Answer Website accessibility is essential for inclusivity and may be legally required under anti-discrimination laws. Composr is designed to meet high accessibility standards, but you need to maintain this when creating content or modifying templates. Following WCAG guidelines is crucial, and you can find more information in the accessibility tutorial.
Question How can I ensure my website complies with email marketing laws?
Answer Email marketing laws like CAN-SPAM protect recipients' rights to unsubscribe. Your website must include a clear 'List-Unsubscribe' header in every email, offer an easy unsubscribe process, and respect unsubscribe requests promptly. Composr provides built-in mechanisms, including an unsubscribe endpoint and support for the List-Unsubscribe header, to facilitate compliance.
Question What are my responsibilities regarding user privacy?
Answer You must have a comprehensive privacy policy that details the personal data you collect, its usage, and if it's shared with third parties. Laws like GDPR have strict requirements, including logging data access, data purging, and security measures. California law mandates specific elements in your policy, like handling "Do Not Track" requests and a clear process for communicating changes.

Composr has an automatic Privacy Policy generator block to help you get started. This is used by default.
Question How can I create effective website rules?
Answer A well-defined rules page is crucial for setting expectations for user behavior and outlining consequences for violations. It should cover a range of offenses with appropriate punishments, reference relevant laws, and assign legal responsibility to users. Composr provides default rules pages that can be customized, and this page is displayed to users upon joining the site.
Question What are the key legal considerations for running a website?
Answer Several legal aspects need careful attention when operating a website, especially for large or corporate sites. These include establishing clear rules and terms of service, adhering to privacy laws like GDPR and California's regulations, managing personal data responsibly, complying with email marketing regulations like CAN-SPAM, ensuring website accessibility, addressing eCommerce regulations, and understanding liability for content and user actions.
Question How do data-tpl and data-view behaviors work in Composr's JavaScript?
Answer Composr uses data-tpl and data-view behaviors for associating HTML templates and JavaScript views, respectively. This facilitates clean separation of presentation and logic:
  • data-tpl: Used with the $cms.behaviors.initializeTemplates function and PARAMS_JSON tempcode directive to bind JavaScript logic to HTML templates.
  • data-view: Used with the $cms.behaviors.initializeViews function to associate JavaScript view classes (inheriting from $cms.View) with specific HTML elements.
Question What are the advantages of using Composr's JavaScript libraries?
Answer Composr's JavaScript libraries like $cms, $util, and $dom offer several advantages:
  • Organization: They provide a structured way to access Composr-specific functionalities, avoiding global namespace pollution.
  • Abstraction: They encapsulate common tasks, simplifying DOM manipulation, form handling, and interaction with Composr's UI.
  • Consistency: They offer a consistent API across different parts of Composr.
Question How does Composr implement the Model-View-Controller (MVC) pattern?
Answer
  • Model/API: The sources directory primarily houses scripts forming the Model/API, handling data logic and business rules.
  • View: Templates in themes/default/templates represent the View, responsible for presenting data to the user. Comcode pages can also be considered part of the View.
  • Controller: Entry scripts like index.php and site/dload.php act as front controllers, directing requests. Modules and blocks, residing in */pages/modules and sources/[mini]blocks, respectively, serve as controllers, managing user interactions and determining which View to render.

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 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.
