Hyper Text Transfer Protocol Secure (HTTPS) is the secure version of HTTP, the protocol over which data is sent between the browser and the website that it is connected to. The 'S' at the end of HTTPS stands for 'Secure'. It means all communications between the browser and the website are encrypted. HTTPS was often used to protect confidential online transactions like online banking and online shopping order forms. Over the years, HTTPS has become the primary mode of access for Web and App tier. Even for NetScaler management access, customers prefer connecting over HTTPS.

Instructions

NetScaler GUI can be accessed through NSIP or SNIP. To secure this access 

1. Go to System, Network and IP’s
   

2. Select NSIP/SNIP and click Edit button to edit the respective configuration.
   

3. Enable “Secure Access only” option under Application Access Controls.
   

This will enable the HTTPS secure access to the GUI of the NetScaler appliance.

If the checkbox “Secure Access Only” is greyed out please select the GUI option on the left and then select the “Secure Access Only”. Once this option is selected and saved, NetScaler management UI can only be reached over HTTPS and any attempt to connect over HTTP would fail.

Note: Secure Access only option can also be enabled during the creation of the SNIP.

To enable Secure Access to GUI during the creation of SNIP through command prompt, use the commands:

add ns ip <IP_Address> <Subnet> -type SNIP -gui SECUREONLY -mgmtAccess ENABLED
