MediaWiki Protection

MediaWiki Protection

MediaWiki protection is a vital feature for maintaining the integrity and stability of a wiki, especially those open to public editing, like Wikipedia. It allows administrators to restrict editing access to specific pages, preventing vandalism, edit wars, and the accidental disruption of important content. This article provides a comprehensive overview of MediaWiki protection, covering its types, implementation, considerations, and best practices for beginners.

What is Page Protection?

Page protection isn't about preventing all access to a page. It's about controlling *who* can edit it. A protected page can still be viewed by anyone with access to the wiki. The level of protection determines the types of users who can make changes. Think of it as different levels of security for different types of content. Highly visible and frequently targeted pages (like the Main Page) require stronger protection than less critical pages.

The core purpose of protection is to balance the wiki's commitment to open collaboration with the need to safeguard important content from unauthorized or disruptive edits. Without protection, a malicious actor could quickly deface a prominent page, or a heated edit war could destabilize a crucial article.

Types of Protection

MediaWiki offers several types of page protection, each suited to different scenarios. Understanding these distinctions is crucial for effective wiki administration.

Full Protection:* This is the most restrictive level. Only administrators (users with the `administrator` user right) can edit a fully protected page. Even autoconfirmed users (see below) are blocked from making changes. Full protection is typically reserved for pages that are highly vulnerable to vandalism, such as the Main Page, high-profile articles about current events, or pages subject to persistent disruptive editing. It's often used temporarily during periods of high activity or controversy.

Semi-Protection:* This allows autoconfirmed users to edit the page, while preventing edits from unregistered users and newly registered accounts. An *autoconfirmed user* is generally defined as a user account that is at least four days old and has made at least ten edits. This is a common and effective protection level for many articles, striking a balance between openness and security. It prevents the most basic forms of vandalism while still allowing legitimate contributors to participate.

Template Protection:* Templates are reusable content blocks used across multiple pages. Protecting a template prevents changes that could inadvertently affect all pages that use it. Template protection can be full or semi-protection, depending on the template's importance and complexity. Incorrectly edited templates can cause widespread disruption, making template protection particularly important. Consider the impact on dependent pages when evaluating template protection.

Cascading Protection:* This is a more advanced feature. When a page is cascading protected, it also protects any templates it transcludes (includes). This prevents users from editing the template through the page, bypassing the template's own protection. Useful for complex templates or when a page relies heavily on a specific template configuration. Cascading protection adds an extra layer of security.

Extended Confirmation Protection (ECP):* Introduced in MediaWiki 1.29, ECP requires users to have *extended confirmed* status to edit a page. Extended confirmed status is granted to accounts that are at least 30 days old, have made at least 500 edits, and have not been blocked within the last 30 days. ECP is a more stringent form of semi-protection, designed to combat sophisticated vandalism and disruptive editing by long-term users who attempt to bypass standard protections. This is a relatively new feature and its usefulness is being continuously evaluated.

Edit Protection (formerly Stable Revision Protection):* This prevents edits to the *content* of a page, but allows edits to the talk page. This is useful for pages that are considered relatively stable and where discussion on the talk page is the preferred method for proposing changes. It’s a softer form of protection focused on preserving a specific version of the content.

How to Protect a Page

Protecting a page requires administrator privileges. Here's a general outline of the process (specific steps may vary slightly depending on your wiki's configuration and skin):

1. Navigate to the Page: Go to the page you want to protect. 2. Access Protection Log: Typically, there's a "Protect" or "Protect this page" link in the page tools menu (often located under the "Tools" section in the sidebar, or in the "More" dropdown menu at the top of the page). 3. Select Protection Type: Choose the appropriate level of protection from the available options (Full, Semi, Template, Cascading, ECP, or Edit Protection). 4. Set Expiration Date (Optional): You can specify an expiration date for the protection. This is useful for temporary protection during events like high-traffic periods or controversial discussions. If no expiration date is set, the protection is indefinite. 5. Provide a Reason: *Always* provide a clear and concise reason for the protection in the "Reason" field. This is important for transparency and accountability, and helps other administrators understand the rationale behind the protection. 6. Save Changes: Click the "Protect page" button to apply the protection.

How to View Protection Logs

The protection log records all protection and unprotection events on the wiki. You can access the protection log to review past protection actions and understand the history of protection on specific pages.

1. Access the Special:Log Page: In your wiki, navigate to Special:Log. 2. Select "Protection": From the "Log type" dropdown menu, select "Protection". 3. Review the Log: The log displays a chronological list of protection and unprotection events, including the page name, the administrator who made the change, the protection type, and the reason provided.

Considerations When Protecting Pages

Protecting pages should not be done lightly. Overuse of protection can stifle collaboration and create a perception of elitism. Here are some key considerations:

Justification:* Always have a clear and justifiable reason for protecting a page. Vague or unsubstantiated reasons are not acceptable.
Least Privilege:* Use the *least restrictive* level of protection necessary to achieve the desired outcome. Avoid full protection if semi-protection would suffice.
Transparency:* Clearly communicate the reasons for protection to the community, ideally on the page's Talk Page.
Temporary Protection:* Favor temporary protection over indefinite protection whenever possible. Regularly review protected pages to determine if the protection is still necessary.
Talk Page Access:* Even when a page is fully protected, the talk page should generally remain accessible for discussion. This allows users to propose changes and engage in constructive dialogue.
Edit Wars:* Protection should not be used to resolve content disputes. Use Mediation and Consensus-building processes instead. Protection can *temporarily* halt an edit war, but it doesn't resolve the underlying issues.
Impact on Collaboration:* Consider the impact of protection on legitimate contributors. Will it hinder their ability to improve the page?
Monitoring:* Regularly monitor protected pages for vandalism or other issues that may require further action.
Abuse of Protection:* Be aware that administrators can abuse protection privileges. Establish clear guidelines and oversight mechanisms to prevent this.

Best Practices for Protection

Start with Semi-Protection:* For most articles, semi-protection is a good starting point.
Use ECP Judiciously:* Reserve ECP for pages targeted by sophisticated vandalism or disruptive editing.
Protect Templates Strategically:* Protect templates that are widely used or particularly vulnerable to disruption.
Cascade Protection When Necessary:* Use cascading protection to prevent bypasses of template protection.
Document Protection Decisions:* Keep a clear record of protection decisions and their rationale in the protection log.
Engage with the Community:* Discuss protection decisions with the community on the talk page.
Review Protection Regularly:* Periodically review protected pages to determine if the protection is still necessary.
Consider Alternative Solutions:* Before resorting to protection, explore alternative solutions like user warnings, blocks, and content dispute resolution.

Protection and Automated Tools

Various bots and automated tools can assist with page protection. These tools can monitor pages for vandalism, identify potential edit wars, and automatically request protection from administrators. Examples include:

ClueBot NG:* A bot that reverts vandalism and can automatically request protection for frequently vandalized pages.
Anti-Vandalism Bots:* Numerous bots are designed to detect and revert vandalism, reducing the need for manual intervention.
Protection Request Tools:* Some wikis have custom tools that allow users to request protection from administrators.
