Create a Decryption Profile (Strata Cloud Manager)

Define traffic for your configuration to decrypt and the type of decryption you want to perform
Follow these steps to create a decryption profile.
  1. Add a decryption profile.
    Select
    Manage
    Configuration
    NGFW and Prisma Access
    Security Services
    Decryption
    ,
    Add Profile
    or modify an existing decryption profile, and give the profile a descriptive
    Name
    .
  2. (
    Optional
    ) Block and control SSL tunneled and/or inbound traffic:
    Although applying a Decryption profile to decrypted traffic is optional, it's a best practice to always apply a Decryption profile to the security rules to protect your network against encrypted threats. You can’t protect yourself against threats you can’t see.
    Select
    SSL/TLS Decryption
    :
    • Select
      Handshake Settings
      to configure the settings that control minimum and maximum protocol versions and key exchange, encryption, and authentication algorithms to enforce on decrypted SSL traffic. These settings are active when this profile is attached to decryption security rules that are set to perform either SSL Forward Proxy decryption or SSL Inbound Inspection.
    • Select
      SSL Forward Proxy
      to configure the settings to verify certificates, enforce protocol versions and cipher suites, and perform failure checks on SSL decrypted traffic. These settings are active only when this profile is attached to a decryption security rule configured to perform SSL Forward Proxy decryption.
    • Select
      SSL Inbound Inspection
      to configure the settings to enforce protocol versions and cipher suites and to perform failure checks on inbound SSL traffic. These settings are active only when this profile is attached to a decryption security rule that performs SSL Inbound Inspection.
  3. (
    Optional
    ) Block and control traffic (for example, a URL category) for which you choose to Create a Security Policy-Based Decryption Exclusion.
    Although applying a Decryption profile to traffic that you choose not to decrypt is optional, it's a best practice to always apply a Decryption profile to the security rules to protect your network against sessions with expired certificates or untrusted issuers.
    Select
    No Decryption
    to configure the Profile for No Decryption and check the
    Block sessions with expired certificates
    and
    Block sessions with untrusted issuers
    boxes to validate certificates for traffic that is excluded from decryption. Create policy-based exclusions only for traffic that you choose not to decrypt. If a server breaks decryption for technical reasons, don’t create a Security policy-based exclusion, add the server to the SSL Decryption Exclusion list (
    Manage
    Configuration
    NGFW and Prisma Access
    Security Services
    Decryption
    Global Decryption Exclusions
    ).
    These settings are active only when the decryption profile is attached to a decryption security rule that disables decryption for certain traffic.
  4. Add the decryption profile when you Create a Decryption Policy Rule.
    Your configuration applies the decryption profile to and enforces the profile’s settings on the traffic that matches the decryption policy rule.
  5. Save
    your configuration.
  6. Select
    Push Config
    to save your configuration and deploy it to your network.
