Description You want to modify the key exchange (KEX) algorithms used by the secure shell (SSH) service on the BIG-IP system. To disable weak key exchange algorithms like diffie-hellman-group1-sha1 and diffie-hellman-group-exchange-sha1 To enable strong

A Nessus scan reported several of our devices are allowing weak key exchange algorithms and I have been asked to disable them. I have specifically been asked to disable: diffie-hellman-group-exchange-sha1 diffie-hellman-group1-sha1 on all devices.
2. To test if weak MAC algorithms are enabled, run the below command: ssh-vv-oMACs=hmac-md5,hmac-md5-96,hmac-sha1,hmac-sha1-96,hmac-md5-etm@openssh.com,hmac-md5-96-etm@openssh.com,hmac-sha1-etm@openssh.com,hmac-sha1-96-etm@openssh.com,umac-64-etm@openssh.com <server> 1....
Test weak CBC ciphers by executing the below command. ssh -vv -oCiphers=3des-cbc,aes128-cbc,aes192-cbc,aes256-cbc If successful, it will prompt for a password. This means weak ciphers are enabled. If it fails, indicating cbc ciphers are disabled, you should receive a message like this...
The security scan shows a week Key Key Exchange Algorithm which needs to be removed from ssh configuration:SSH Server Supports Weak Key Exchange AlgorithmsCVSS Score: 4.30Description: The server supports one or more weak key exchange algorithms. It is highly adviseable to remove weak key exchange...
algorithms which are considered weak and support Cipher Block Chaining (CBC) encryption which may allow an attacker to recover the plaintext from the ciphertext. Well, this tutorial is all about how to disable weak key exchange algorithms and CBC encryption mode in the SSH server onCentOS ...
weak key exchange method supported by Server. The criteria of a weak KEX method is as follows: The SSL/TLS server supports key exchanges that are cryptographically weaker than recommended. Key exchanges should provide at least 112 bits of security, which translates to a minimum key size of ...
