The firewall can use three multi-factor authentication methods to authenticate access to the firewall: SMS, user certificate, and one-time password. These methods can be used in combination with other authentication factors, such as username and password, to provide stronger security for accessing the firewall web interface or CLI. The firewall can integrate with various MFA vendors that support these methods through RADIUS or SAML protocols5. Voice and fingerprint are not supported by the firewall as MFA methods. References: MFA Vendor Support, PCNSE Study Guide (page 48)

The Exceptions settings allows you to change the response to a specific signature. For example, you can block all packets that match a signature, except for the selected one, which generates an alert. The Exception tab supports filtering functions.

If you not believed, then login the firewall go to Vulnerability > Exceptions and select "Show all signatures". From there you will see all threat information including specific actions.

The image shows an IKE Gateway configuration where Site B is set to IKEv1 only mode, and passive mode is not enabled. For dynamic peering to work when Site A is using a DHCP assigned address:

Passive mode on Site A needs to be disabled. In passive mode, the firewall will not initiate the IKE negotiation and will only respond to negotiation requests from the peer. Since Site A has a dynamic IP, it must be able to initiate the connection to Site B, which has a static IP.

Matching the IKE version between Site A and Site B is also necessary for successful IPSec tunnel establishment. Since Site B is set to IKEv1 only mode, Site A also needs to be configured to use IKEv1 to ensure that both sites are using the same version for the IKE negotiation process.

NAT Traversal is used when there are NAT devices between the two endpoints, but there's no indication that this is the case here. Additionally, local identification on Site A is not necessarily related to the issue with dynamic peering not working.

To create an application-based Security policy rule to allow Evernote, the administrator only needs to add the Evernote application to the Security policy rule. The Evernote application is a predefined App-ID that identifies the traffic generated by the Evernote client or web interface. The Evernote application implicitly uses SSL and web browsing as dependencies, which means that the firewall automatically allows these applications when the Evernote application is allowed. Therefore, there is no need to add HTTP, SSL, or web browsing applications to the same Security policy rule. Adding these applications would broaden the scope of the rule and potentially allow unwanted traffic12. References: App-ID Overview, Create a Security Policy Rule

When using certificate authentication for firewall administration on Palo Alto Networks devices, the method used for authorization is typically the Local database. Certificate authentication ensures that the entity attempting to access the firewall is in possession of a valid certificate. Once the certificate is validated for authentication, the authorization process determines what level of access or permissions the authenticated entity has. This is usually managed locally on the firewall, where administrators can define roles and permissions associated with different users or certificates. Thus, the authorization process, in this case, leverages the Local database to enforce access controls and permissions, aligning with best practices for secure management of network devices.
