With the recent introduction of Putty version 0.68 you may now get the following Security Alert when SSH’ing to Cisco ASA firewalls. See this link for more info on why.
Getting rid of this nag, i.e. improving the security of your firewall, is simple.
Update your crypto general-keys pair to a 2048-bit modulus, and then change the SSH key-exchange group. Here’s the code:
firewall(config)# crypto key generate rsa general-keys modulus 2048 WARNING: You have a RSA keypair already defined named <Default-RSA-Key>. Do you really want to replace them? [yes/no]: yes Keypair generation process begin. Please wait... firewall(config)# ssh key-exchange group dh-group14-sha1
