Cisco Secure ACS Admin Sessions SSL Certificate for HTTPS
If you have been using a certificate that has been created or issued by Microsoft Certificate Authority (CA), you will notice that you don’t have to set up the SSL Certificate yourself since Cisco already uses Microsoft-issued SSL Certificates for administrative sessions. But since self-signed certificates are now accommodated by Cisco, you can create a self-signed certificate and install it so that you can have a secured connection.
You can also use SSL Certificates that are issued by external Certificate Authorities. This Cisco Secure ACS Admin Sessions SSL Certificate for HTTPS connection is available from reputable and well-known Certificate Authorities. Be sure to get these certificates from only trusted ones to ensure that the certificate that you will use will be recognized by the system, enabling your admin sessions to be safe and secured.

Using Self-Signed and CA Signed SSL Certificates on Cisco
Here are some things that you need to keep in mind when using a self-signed or a CA signed SSL Certificate to make your connection secured:
- Requirements
You need to ensure that you have all the requirements before you start installing the certificate of your choice. This will make things easier as you do not have to stop working in the middle of the installation just to get the thing that you need ready.
- ACS 3.1.1 or Later
You need at least ACS version 3.1.1 to be able to use a self-signed certificate or an SSL Certificate issued by a Certificate Authority.
- Microsoft CA Server
If you will be creating your own self-signed certificate, you will need the Microsoft CA Server.
- Internet Information Server (IIS)
Before you start installing the SSL Certificate that you want to use for Cisco, you need to ensure that you have already installed and set this up.
- Self-Signed SSL Certificate
When creating a self-signed certificate using the ACS server, ensure that the key length of the certificate that you are making is at least 1024. This is to ensure that the certificate will have the required key length, which will ensure that the connection will be secured.
Cisco Secure ACS Admin Sessions SSL Certificate for HTTPS requires at least 1024 key length to be able to protect the connection properly. Since admin sessions are important, they should be protected immensely to be able to protect your projects and intellectual property.
The 1024 key length is also the recommended key length as this is the most compatible one. Do not try to make the key length any longer, regardless of the fact that the ACS server can create longer key lengths, as this will cause problems during the authentication process, which will cause problems with the admin session connection.
When using an SSL Certificate for Cisco Secure ACS Admin Sessions, ensure that you install the certificate properly. Make sure that you enable the HTTPS connection for admin sessions and test it out to ensure that the certificate is working properly. Use only certificates from trusted CAs if you are using an external one to ensure that it will be accepted by the system.
