PT0-002 Dumps with Practice Exam Questions Answers

An application security assessment report aimed at developers typically includes information critical to understanding and improving the security and stability of the application. Poor input sanitization and null pointer dereferences are two such issues that are directly related to application security and can lead to significant vulnerabilities such as injection attacks or crashes. Poor input sanitization exposes the application to various forms of injection attacks, where an attacker could supply malicious input to gain unauthorized access or disrupt application services. Null pointer dereferences, on the other hand, can lead to application crashes or unexpected behavior, which can be exploited to compromise application security or availability. Highlighting these issues helps developers focus on areas that need immediate attention to enhance the application's security posture.

IoT devices are often shipped with default passwords, which are easily discoverable and widely known. Many users fail to change these default credentials, leaving the devices vulnerable to unauthorized access. This issue is one of the most common vulnerabilities associated with IoT devices connected directly to the internet. Attackers can exploit these default passwords to gain control over the devices, potentially leading to a range of malicious activities, including the recruitment of the devices into botnets for Distributed Denial of Service (DDoS) attacks, data breaches, or other cybercriminal activities.

The Nmap command uses the Xmas scan technique, which sends packets with the FIN, PSH, and URG flags set. This is an attempt to bypass firewall rules and elicit a response from open ports. However, if the target responds with an RST packet, it means that the port is closed. Open ports will either ignore the Xmas scan packets or send back an ACK packet. Therefore, the information most likely indicates that all of the ports in the target range are closed.

Kismet is a well-known tool used in penetration testing for wireless network detection, packet sniffing, and intrusion detection. It is particularly useful for gathering information about Wi-Fi networks as it can detect hidden networks and capture network packets. This capability allows penetration testers to analyze the wireless environment, identify potential vulnerabilities, and assess the security posture of the Wi-Fi equipment being tested. Unlike the other tools listed, Kismet is specifically designed for wireless network analysis, making it the ideal choice for this task.

 Access Points (APs) are crucial in a wireless security assessment as they are the main points through which devices connect to the network. Identifying and securing APs ensures network integrity and security.

 Details:

A. Frequencies: Important but not as critical as identifying and assessing APs.

B. APs: Central to the network's security; assessing AP configurations, placements, and security settings is essential.

C. SSIDs: Identifying SSIDs is part of the assessment but does not provide a complete picture without evaluating APs.

D. Signal strengths: Useful for understanding coverage but secondary to assessing AP security.

 References: Wireless security assessments prioritize AP evaluation as they are the entry points to the network, as outlined in various wireless security frameworks and methodologies.
