  description: |
    Checks whether cookies in the HTTP response contain the Secure attribute. If the Secure flag is set, it means that the cookie can only be transmitted over HTTPS
  impact: |
    Lack of Secure flag on cookies allows the cookie to be sent over unsecure HTTP, making it vulnerable to man-in-the-middle (MITM) attacks.
  remediation: |
    Ensure that all cookies are set with the Secure attribute to prevent MITM attacks.
