Here are some mitigation techniques for IDOR vulnerabilities

 IDOR (Insecure Direct Object Reference) is a type of vulnerability that occurs when an application exposes a reference to an internal implementation object, such as a database record, without performing the proper authorization checks. Attackers can use this vulnerability to access or manipulate data that they should not have access to.

Here are some mitigation techniques for IDOR vulnerabilities:

Implement proper access control: 

Access control is the process of ensuring that only authorized users can access resources. By implementing proper access control, you can prevent unauthorized users from accessing sensitive data.

Use indirect object references:

 Indirect object references use a reference to an intermediate identifier that is mapped to the actual implementation object. By using indirect object references, you can prevent attackers from directly manipulating object references.

Perform input validation:

 Input validation is the process of checking user input to ensure that it conforms to a specific format or data type. By validating input, you can prevent attackers from manipulating object references by injecting malicious data.

Implement logging and monitoring: 

Logging and monitoring can help detect and respond to IDOR attacks. By logging and monitoring access to sensitive resources, you can detect unauthorized access attempts and take appropriate action.

Use a secure coding standard:

 A secure coding standard can help ensure that developers write secure code that is not vulnerable to IDOR attacks. By following a secure coding standard, you can prevent IDOR vulnerabilities from being introduced into your codebase.

In summary, IDOR vulnerabilities can have serious consequences, but there are several mitigation techniques that can help prevent them. By implementing proper access control, using indirect object references, performing input validation, implementing logging and monitoring, and using a secure coding standard, you can protect your application from IDOR attacks.
