Important Palo Alto Networks Cybersecurity-Practitioner Exam Questions

Answer: B

Explanation:

DNS tunneling is an attack technique where data packets are disguised as DNS queries and sent to a remote server. That server, often under the attacker's control, responds with additional data or instructions, effectively creating a covert command-and-control (C2) channel over DNS.

Answer: A, C, E

Explanation:

The six pillars include:

1. Business (goals and outcomes)

2. People (who will perform the work)

3. Interfaces (external functions to help achieve goals)

4. Visibility (information needed to accomplish goals)

5. Technology (capabilities needed to provide visibility and enable people)

6. Processes (tactical steps required to execute on goals)

All elements must tie back to the business itself and the goals of the security operations

Answer: C

Explanation:

Containers are portable and lightweight alternatives to virtual machines that allow developers to package, isolate, and deploy applications across different cloud environments. Containers simplify the building and deploying of cloud native applications by providing consistent and efficient development, testing, and production environments. Containers also offer benefits such as rapid provisioning, high scalability, resource optimization, and security isolation.Reference:

Explanation:

One of the best practices for securing sensitive data in SaaS applications is to control the access and usage of data based on the device type. Managed devices are those that are enrolled and monitored by the organization's IT department, and have security policies and controls applied to them. Unmanaged devices are those that are not under the organization's control, such as personal laptops or mobile phones. Allowing downloads to managed devices but blocking them from unmanaged devices prevents data leakage and unauthorized access to sensitive data.This can be achieved by using a cloud access security broker (CASB) solution, such as Prisma SaaS from Palo Alto Networks, which can enforce granular policies based on device posture, user identity, and data sensitivity12.Reference:1: Securing SaaS applications on the cloud is a critical aspect of protecting sensitive data and maintaining the trust of customers.By implementing best practices, such as enhanced authentication, data encryption, Break Glass, and oversight, organizations can mitigate the security risks associated with SaaS applications2: Prisma SaaS - Palo Alto Networks

Answer: C

Explanation:

A perimeter-based network security strategy relies on firewalls, routers, and other devices to create a boundary between the internal network and the external network. This strategy assumes that every internal endpoint can be trusted, and that any threat comes from outside the network. However, this assumption is flawed, as internal endpoints can also be compromised by malware, phishing, insider attacks, or other methods. Once an attacker gains access to an internal endpoint, they can use it to move laterally within the network, bypassing the perimeter defenses. Therefore, a perimeter-based network security strategy is not sufficient to protect an organization's endpoint systems, and a more comprehensive approach, such as Zero Trust, is needed.Reference:
