Check for DES encryption method

If the result is positive, there is no need for further action. If the result is negative, please read the following instructions.

Result positive Outdated DES encryption method not supported
Result negativ Outdated DES encryption method supported
Description Your web server/website is configured to support the outdated DES encryption method (cipher suite), which is regarded as insecure. This makes you vulnerable to man-in-the-middle-attacks.
Background The term cipher suite stands for a cryptographic protocol that contains the key exchange method, the signature method, the encryption, and cryptographic hash functions. This combination of cryptographic components ensures that there is a secure connection for the communication between two parties, for example your browser and a web server or website. In the TLS protocol (Transport Layer Security), the cipher suite determines which algorithms are used to establish a secure data connection.
Consequence The DES encryption method is not sufficiently secure and thus allows attackers to decode the communication between your website and your customer's browser. In this way, information such as passwords, data entered in forms, or credit card information can be intercepted and misused for criminal purposes. This type of attack is called man-in-the-middle-attack.
Solution/Tips If Outdated DES encryption method supported was reported, deactivate support for the DES encryption method in your web server software.
