What is meant by URL rewriting?

In the context of cybersecurity, link rewriting can be used to improve the security of a website or web application. Here are a few ways that link rewriting can be used for security purposes:

• To obscure the underlying directory structure of a website: Link rewriting can be used to hide the underlying directory structure of a website, making it more difficult for attackers to locate sensitive files or directories. This can help to prevent directory traversal attacks and other types of attacks that rely on knowledge of the directory structure.
• To redirect traffic from a non-secure website to a secure one: If a website or web application is available over both secure (HTTPS) and non-secure (HTTP) connections, link rewriting can be used to redirect traffic from the non-secure version to the secure version. This helps to prevent eavesdropping and other types of attacks that can occur over non-secure connections.
• To add tracking parameters to links: Link rewriting can be used to add tracking parameters to links in order to track clicks and other user interactions. This can help to identify malicious activity and to monitor the effectiveness of security controls.

In the context of email security, link rewriting can be used to help protect against phishing attacks and other types of email-based threats. Here are a few ways that link rewriting can be used for email security purposes:

• To obscure the true destination of a link: Link rewriting can be used to hide the true destination of a link in an email message. This can help to prevent phishing attacks, in which attackers use links to trick users into visiting malicious websites or disclosing sensitive information.
• To track clicks: Link rewriting can be used to add tracking parameters to links in email messages in order to track clicks and other user interactions. This can help to identify malicious activity and to monitor the effectiveness of security controls.
• To redirect traffic: Link rewriting can be used to redirect traffic from a link in an email message to a different destination. This can be used, for example, to redirect traffic from a malicious website to a safe website.

Overall, link rewriting can be a useful tool for improving the security of email messages by obscuring the true destination of links, adding tracking parameters, and redirecting traffic.
