PT0-002 Online Practice Questions and Answers

Correct Answer: D

A static application-security test (SAST) is a type of software testing that analyzes the source code, bytecode or binary code of an application for potential vulnerabilities, such as injection flaws, cross-site scripting, buffer overflows and insecure data handling. A SAST report should provide the application developers with detailed information about the location, severity and impact of the identified vulnerabilities, as well as recommendations for remediation. One of the most important elements to include in a SAST report is the code context for each vulnerability, which shows the relevant code snippets where the issue occurs, as well as the data flow and control flow paths that lead to the vulnerability. This helps the developers understand the root cause of the problem and how to fix it. Code context is especially important for instances of unsafe typecasting operations, which are a common source of security weaknesses in applications. Typecasting is the process of converting one data type to another, such as from an integer to a string. Unsafe typecasting occurs when the conversion is done without proper validation or sanitization, which can lead to unexpected behavior, memory corruption, data loss or code execution. For example, in C/C++, casting a pointer to an incompatible type can result in undefined behavior or buffer overflows. Therefore, a SAST report should include the code context for instances of unsafe typecasting operations, so that the developers can review and correct them.

Correct Answer: D

Rules of engagement (ROE) is a document that outlines the specific guidelines and limitations of a penetration test engagement. The document is agreed upon by both the penetration testing team and the client and sets expectations for how the test will be conducted, what systems are in scope, what types of attacks are allowed, and any other parameters that need to be defined. ROE helps to ensure that the engagement is conducted safely, ethically, and with minimal disruption to the client's operations.

Correct Answer: D

Correct Answer: D

Correct Answer: B

RBAC is best for preventing unauthorized modification by assigning permissions to roles rather than individuals, ensuring that only authorized users can access critical data based on their role within the organization.

Correct Answer: D

SMTP is a protocol associated with mail servers. Therefore, for a penetration tester, an open relay configuration can be exploited to launch phishing attacks.

Correct Answer: C

In Python socket programming, SOCK_DGRAM type is connectionless. This means that the socket does not establish a reliable connection between the sender and the receiver, and does not guarantee that the packets will arrive in order or without errors. SOCK_DGRAM type is used for UDP (User Datagram Protocol) sockets, which are faster and simpler than TCP (Transmission Control Protocol) sockets3.

Correct Answer: A

The output of the Nmap command shows that the remote host supports RC4 ciphers, which are considered weak and vulnerable to several attacks, such as the BEAST and the RC4 NOMORE attacks. RC4 ciphers should not be used in modern TLS implementations, and they are not supported by TLS 1.3. Therefore, the penetration tester should include this finding in the report and recommend disabling RC4 ciphers on the server.

Correct Answer: B

The output provided indicates the use of the NTP protocol (Network Time Protocol) for querying a target system. The reference to "Public Clients" and the specific IP addresses listed, along with the mention of "Other Associations" and the use of NTP version 2, points towards the execution of an NTP monlist request. The monlist feature in NTP servers can be used to obtain a list of the last 600 hosts that have interacted with the NTP server. The command nmap -sU -pU:123 -Pn -n --script=ntp-monlist specifically targets NTP servers on UDP port 123 to retrieve this information, making it the correct choice based on the output shown.
