A company is deploying User-ID in their network. The firewall team needs to have the ability to see and choose from a list of usernames and user groups directly inside the Panorama policies when creating new security rules.
How can this be achieved?
For company compliance purposes, three new contractors will be working with different device groups in their hierarchy to deploy policies and objects. Which type of role-based access is most appropriate for this project?
The Device Group and Template Admin role is tailored for managing specific device groups and templates in Panorama, allowing contractors to deploy policies and objects within their assigned scope without broader administrative access. This aligns with compliance by restricting privileges.
Option B (Dynamic Admin) is undefined in PAN-OS; Panorama Admin is too broad. Option C (Read-only Superuser) prevents configuration changes. Option D (Custom Panorama Admin) could work but requires more setup than the predefined role. Documentation recommends this role for such scenarios.
A new firewall has the Threat Prevention subscription, but the Antivirus does not appear in Dynamic Updates.
What must occur to have Antivirus signatures update?
Which two key exchange algorithms consume the most resources when decrypting SSL traffic? (Choose two.)
The two key exchange algorithms that consume the most resources when decrypting SSL traffic are ECDHE and DHE. These are both Diffie-Hellman based algorithms that enable perfect forward secrecy (PFS), which means that they generate a new and unique session key for each SSL/TLS session, and do not reuse any previous keys. This enhances the security of the encrypted communication, but also increases the computational cost and complexity of the key exchange process. ECDHE stands for Elliptic Curve Diffie-Hellman Ephemeral, which uses elliptic curve cryptography (ECC) to generate the session key. DHE stands for Diffie-Hellman Ephemeral, which uses modular arithmetic to generate the session key.Both ECDHE and DHE require more CPU and memory resources than RSA, which is a non-PFS algorithm that uses public and private keys to encrypt and decrypt the session key123.Reference:Key Exchange Algorithms,Best Practices for Enabling SSL Decryption, PCNSE Study Guide (page 60)
ln a security-first network, what is the recommended threshold value for apps and threats to be dynamically updated?
Schedule content updates so that they download-and-install automatically. Then, set a Threshold that determines the amount of time the firewall waits before installing the latest content. In a security-first network, schedule a six to twelve hour threshold. https://docs.paloaltonetworks.com/pan-os/8-1/pan-os-admin/threat-prevention/best-practices-for-content-and-threat-content-updates/best-practices-security-first.html#id184AH00F06E
