Security team has scanned our sl3000 and its reporting weak algorithms supported Plugin Output: "The following weak server-to-client encryption algorithms are supported : arcfour arcfour128 arcfour256" "The rem
What are SSH Weak MAC Algorithms? As with most encryption schemes, SSH MAC algorithms are used to validate data integrity and authenticity. A ‘MAC algorithm’ should not be conflated with a MAC (Message Authentication Code) as these are two distinct components. The MACalgorithmuses a message ...

For example, old clients that only support those weak algorithms may not connect with a new SSH server. Let’s see an example of a compatibility issue arising from a cipher mismatch. Suppose, we’ve got a server with supported ciphers asaes128-ctr,aes192-ctr,aes256-ctr,andaes128-cbc: ...
The version of software may not support the "ip ssh server algorithm kex" command. If you type "show run all | i ssh" you should see the command if its supported. Using the default values, this command is usually hidden, which is why you would want to use the show run all command....

Step 3. Disable SSH v1 SSH v1 is insecure and should be disabled. Enter the following command: ip ssh version 2 1. Step 4. Remove weak SSH ciphers Remove the weak CBC and 3DES algorithm encryption ciphers. Enter the following command: ...
Signature Algorithm: sha1WithRSAEncryption SAN: IP:VP_IP, DNS:VP_DNS CA:False If CA field is 'False', then it’s a self-signed certificate and if the user is using vVols, then a new self signed certificate needs to be generated and installed on VASA provider which has at least SHA...
