Cisco ASA – Allow HTTPS/ASDM – Via ASDM (version shown 6.4(7)). OK, the title of this might raise an eyebrow, but if you have access to the ASDM and you want to grant access to another IP/Network them you might want to do this. Connect via ASDM Navigate to Configuration Device Management Management Access ASDM/HTTPS/Telnet/SSH Add Select ASDM/HTTPS Supply the IP. Remain in Configuration Device Management Management Access ASDM/HTTPS/Telnet/SSH. Under 'Specify the addresses of all hosts/networks which are allowed to access the ASA using ASDM/HTTPS/Telnet/SSH', you should add the static IPs of the devices or servers you wish to access the firewall from. Click Add on the right.
How I create RSA key and enable SSH access in Cisco VG202, in a Cisco router I use the next commands(but in a VG not exists): conf t. Crypto key generate rsa modulus 1024. Ip domain-name domain-name. Cisco ASA SSH, Don’t Forget To Generate A Key. The fact that Cisco doesn’t do this automatically makes me very very nervous. The networks running Cisco appear. The fact that Cisco doesn’t do this automatically makes me very very nervous. I’m not saying thatbut they do still pretty much default to telnet. One must even be sure to pull the IOS image for switches and routers that supports SSH. I don’t do anything with Cisco (routers/switches) and I haven’t used them in ages.
This guide will walk you through the basics of hardening SSH access to your Cisco ASA firewall using ASDM. If you're like me, you'd rather have a GUI than spending the day Googling CLI commands.
4 Steps total
Step 1: Login to ASDM
Step 2: Change the default allow SSH version from 1 to 2
Go to Configuration > Device Management > Management Access > ASDM/HTTPS/Telnet/SSH
Under SSH Settings, change the value of 'Allowed SSH Version(s)' from 1 to 2.
Step 3: Change the default Diffie-Hellman group from 1 to 14
Under 'Specify the addresses of all hosts/networks which are allowed to access the ASA using ASDM/HTTPS/Telnet/SSH', you should add the static IPs of the devices or servers you wish to access the firewall from.
Click Add on the right.
Select the radio button next to SSH.
Select 'Inside' as the interface.
Enter the static IP of the device/server.
Enter 255.255.255.255 as the subnet mask.
Click OK.
Repeat for all remaining devices/servers or specify any outside IPs which are static that require remote access.
WARNING: If your firewall has 0.0.0.0 'any' enabled by default, make sure you save your changes by adding your static IP first before deleting the 'any' entry. Otherwise, your session will disconnect.
You may repeat the last step for hardening access to ASDM as well.

That's a good idea! I shall have to work on implementing it at my workplace.
