Answer : C

Stateful packet inspection firewalls Second-generation stateful packet inspection (also known as dynamic packet filtering) firewalls have the following characteristics:

They operate up to Layer 4 (Transport layer) of the OSI model and maintain state information about the communication sessions that have been established between hosts on the trusted and untrusted networks.

They inspect individual packet headers to determine source and destination IP address, protocol (TCP, UDP, and ICMP), and port number (during session establishment only) to

determine whether the session should be allowed, blocked, or dropped based on configured

firewall rules.

After a permitted connection is established between two hosts, the firewall creates and

deletes firewall rules for individual connections as needed, thus effectively creating a tunnel that allows traffic to flow between the two hosts without further inspection of individual packets during the session.

This type of firewall is very fast, but it is port-based and it is highly dependent on the

trustworthiness of the two hosts because individual packets aren't inspected after the

connection is established.

Answer : C

'Remember that a trust zone is not intended to be a ''pocket of trust'' where systems (and therefore threats) within the zone can communicate freely and directly with each other. For a full Zero Trust implementation, the network would be configured to ensure that all communications traffic, including traffic between devices in the same zone, is intermediated by the corresponding Zero Trust Segmentation Platform.'

Answer : C

Palo Alto Networks Cortex XDR is an extended detection and response platform that provides endpoint protection, threat detection, and incident response capabilities.When an endpoint is asked to run an executable, Cortex XDR does the following steps1:

First, it sends the executable to WildFire, a cloud-based malware analysis and prevention service, to determine if it is malicious or benign.WildFire uses static and dynamic analysis, machine learning, and threat intelligence to analyze the executable and provide a verdict in seconds2.

Next, it checks the execution policy, which is a set of rules that define what actions are allowed or blocked on the endpoint.The execution policy can be configured by the administrator to enforce granular control over the endpoint behavior3.

Then, it runs a static analysis, which is a technique that examines the executable without executing it.Static analysis can identify malicious indicators, such as file signatures, hashes, strings, and embedded resources4.

Finally, it runs a dynamic analysis, which is a technique that executes the executable in a sandboxed environment and monitors its behavior.Dynamic analysis can detect malicious activities, such as network connections, registry changes, file modifications, and process injections4.

Answer : A

An evil twin is a type of Wi-Fi attack that involves setting up a fake malicious Wi-Fi hotspot with the same name as a legitimate network to trick users into connecting to it. The attacker can then intercept the user's data, such as passwords, credit card numbers, or personal information. The victim initiates the connection by choosing the fake network from the list of available Wi-Fi networks, thinking it is the real one. The attacker can also use a deauthentication attack to disconnect the user from the legitimate network and force them to reconnect to the fake one.Reference:

Endpoint antivirus software is a type of software designed to help detect, prevent, and eliminate malware on devices, such as laptops, desktops, smartphones, and tablets. Endpoint antivirus software can block viruses that are not seen and blocked by the perimeter firewall, which is a network security device that monitors and controls incoming and outgoing network traffic based on predefined security rules. Perimeter firewall can block some known viruses, but it may not be able to detect and stop new or unknown viruses that use advanced techniques to evade detection.Endpoint antivirus software can provide an additional layer of protection by scanning the files and processes on the devices and using various methods, such as signatures, heuristics, behavior analysis, and cloud-based analysis, to identify and remove malicious code123.Reference:

Answer : C

Command and Control: Attackers establish encrypted communication channels back to command-and-control (C2) servers across the internet so that they can modify their attack objectives and methods as additional targets of opportunity are identified within the victim network, or to evade any new security countermeasures that the organization may attempt to deploy if attack artifacts are discovered.

Answer : B

SecOps is the organizational function that is responsible for security automation and eventual vetting of the solution to help ensure consistency through machine-driven responses to security issues. SecOps is a collaboration between security and operations teams that aims to align their goals, processes, and tools to improve security posture and efficiency. SecOps can leverage automation to simplify and accelerate security tasks, such as threat detection, incident response, vulnerability management, compliance enforcement, and more. Security automation can also reduce human errors, enhance scalability, and free up resources for more strategic initiatives.Reference:
