Step 3: Change the default Diffie-Hellman group from 1 to 14 Under SSH Settings, change the value of 'Allowed SSH Version(s)' from 1 to 2. Go to Configuration > Device Management > Management Access > ASDM/HTTPS/Telnet/SSH Configure Ssh Cisco Asa 4 Steps total Step 1: Login to ASDM Step 2: Change the default allow SSH version from 1 to 2 If you're like me, you'd rather have a GUI than spending the day Googling CLI commands. This guide will walk you through the basics of hardening SSH access to your Cisco ASA firewall using ASDM. The larger the key modulus size you specify, the longer it takes to generate the RSA key pair. Generate an RSA key pair for the ASA Firewall, which is required for SSH: ASA(config)#crypto key generate rsa modulus modulussizeNote: The modulussize (in bits) can be 512, 768, 1024, or 2048. The syslog server in this example is Spunk but almost any syslog server should be do the job. This article is intended to be a simple example of configuring An圜onnect relevant syslog messages to be sent from the ASA to a Syslog server. Solution On older versions of the ASDM you could generate the keypair in the Identification Certificates section (well you still can but only if you are also generating a certificate request file). To reload the service immediately, in the window that appears, select Reload Start Time: Now, then click Schedule Reload.Now at command line you can fix this with a ‘Crypto Key Generate RSA Modulus 2048‘ command, but you can’t get to command line only ASDM. Log in to the Cisco Adaptive Security Device Manager.

This step is important, as you need to ensure that the ASA firewall works properly and is accessible after a single reload. Log in via the SSH protocol, and run the following command:Īddress or name of remote host ? We recommend taking note of these details, and keeping them to hand. Here, you will see the Cisco ASA and ASDM versions you are using. Log in to the Cisco Adaptive Security Device Manager, then go to Device Information, and General. Check the binary image that is currently being used First method: Via the ASDM You now need to disable the Cisco ASA firewall again, as you did in the first step. Disable the Cisco ASA firewall again through the Control Panel If you experience any issues, carry out the checks required to resolve them before you move onto the next steps. If everything works, move onto the next step. Next, click Enable the Cisco ASA firewall, on the right-hand side.Īfter the reload, once the ASA firewall is enabled again, check that all of your server's services are working properly. Select your dedicated server, then Cisco ASA Firewall. Re-enable the Cisco ASA firewall through the Control PanelĪs per the first step, go to your OVHcloud Control Panel, and open the Bare Metal Cloud section. The reboot to reload the configuration will take a few minutes. Log in to your Cisco Adaptive Security Device Manager (ASDM), then choose File and Save Running Configuration to Flash. Next, click Disable the Cisco ASA firewall, on the right-hand side.Īpply configuration First method: Via the ASDM Then select your dedicated server, and Cisco ASA Firewall. To do this, go to your OVHcloud Control Panel, and open the Bare Metal Cloud section.

For this reason, we recommend disabling the Cisco ASA firewall, so that your server does not experience any outages during the upgrade process. The upgrade process will require your system to reboot several times. Instructions Disable the Cisco ASA firewall through the Control Panel You must have access to your OVHcloud Control Panel.
