To ensure trust between parties in a secure communication session,
Prisma Access
uses
digital certificates. Each certificate contains a cryptographic key to encrypt
plaintext or decrypt ciphertext. Each certificate also includes a digital signature
to authenticate the identity of the issuer. The issuer must be in the list of
trusted certificate authorities (CAs) of the authenticating party. Optionally, the
authenticating party verifies the issuer did not revoke the certificate. Prisma
Access uses certificates to secure features like decryption and authentication, and
to secure communication between all the clients, servers, users, and devices
connecting to your network.
