Secure protocols and storage system access
Using secure protocols improves the security of your storage system by making it very difficult for someone to intercept a storage system administrator's password over the network, because the password and all administrative communication are encrypted.
If your storage system does not have secure protocols enabled, you can set up SecureAdmin, which provides a secure communication channel between a client and the storage system by using one or both of the following protocols—SSH and SSL.
Note: SecureAdmin is set up automatically on storage systems shipped with Data ONTAP 8.0 or later.
•
Secure Shell (SSH) protocol
SSH provides a secure remote shell and interactive network session.
•
Secure Sockets Layer (SSL) protocol
SSL provides secure Web access for Data ONTAP APIs.
