When integrating Cisco Cloudlock with SaaS platforms like Salesforce, two core authorizations are required:
network access and API authorization. In the scenario, Cloudlock has been authorized in Salesforce, and its IP has been allow-listed. However, if access is still denied, the most likely cause is that Salesforce has not been configured to accept traffic from Cloudlock's IP range - a process handled from the Salesforce admin panel.
To resolve the issue, network access must be explicitly granted to Cloudlock from within Salesforce. This ensures that Salesforce accepts requests initiated by Cloudlock for monitoring and enforcement.

Multifactor Authentication (MFA) is one of the most effective mitigations against brute-force attacks. Even if an attacker guesses or steals a user's password, they would still need a second authentication factor (e.g., push notification, hardware token, biometric verification) to complete login.
SCAZT Section 2: User and Device Security (Pages 40-43) emphasizes the importance of MFA in protecting identities from password spraying, credential stuffing, and brute-force attacks.

When integrating Cisco ISE with Azure AD using SAML SSO:
B: The Azure AD metadata must be uploaded into ISE to establish trust and allow token validation.
D: External Identity Sources settings must be configured in ISE to recognize and process authentication requests via SAML-based identity providers like Azure AD.
These are mandatory steps for enabling browser-based SSO authentication in ISE as explained in SCAZT Section 2 (User and Device Security, Pages 42-44), which describes federated identity integration.
Note: Option A is already completed as stated in the prompt. Options C and E are not essential to the authentication flow in this SAML context.

The anyconnect keep-installer none command is used to remove the Cisco Secure Client (formerly AnyConnect) from an endpoint once the VPN session ends. This is useful in temporary or kiosk-based access environments. The default behavior retains the client.
This capability is covered in SCAZT Section 2: User and Device Security (Pages 40-44), which outlines VPN session lifecycle management and Secure Client policies.
