Paloalto Networks PSE-Strata Exam With Confidence Using Practice Dumps

When beginning to understand the Zero Trust protect surface using the Palo Alto Networks Zero Trust reference architecture, the following two steps are crucial:

Validate User Identities through Authentication (A): This step involves ensuring that all users are authenticated properly. By verifying the identities of users attempting to access the network, organizations can ensure that only authorized users can access sensitive resources. This is a fundamental principle of Zero Trust, which operates on the premise of "never trust, always verify."

Categorize Data and Applications by Levels of Sensitivity (C): This involves identifying and classifying data and applications based on their sensitivity and importance to the organization. By understanding what needs to be protected and the level of sensitivity, security policies can be tailored to provide appropriate levels of protection. This helps in prioritizing security measures based on the criticality of the data and applications.

The command show mlav cloud-status is used to verify that the machine learning-based antivirus (MLAV) for portable executable (PE) files is functioning correctly within the Palo Alto Networks WildFire environment. This command provides the status of the machine learning model updates and their integration with the antivirus profile. If the model is working properly, this command will return information indicating that the MLAV service is active and synchronized with the cloud-based threat intelligence. This ensures that the firewall is effectively leveraging machine learning to identify and block malicious PE files.

DNS Sinkholing is a powerful feature in network security that offers several advantages:

Forging DNS replies to known malicious domains: This technique redirects malicious domain queries to a designated IP address (sinkhole), effectively preventing the malware from communicating with its command and control servers, thereby neutralizing its threat.

Working upstream from the internal DNS server: DNS Sinkholing can be implemented upstream, meaning it intercepts and manipulates DNS queries before they reach the internal DNS server. This preemptive action helps in blocking threats early in the DNS resolution process, providing an additional security layer​ (Palo Alto Networks)​​ (Palo Alto Networks)​.
