A Network Protocol Analyzer, such as Wireshark, is a tool that captures and analyzes packets in real-time, displaying them in a human-readable format. It allows network administrators to inspect individual packets deeply, which is essential for identifying and investigating data leaks within an organization. By examining the packet contents, the source and destination of the traffic, and other details, a Network Protocol Analyzer can help pinpoint the exact nature and origin of a data leak.

References: The use of Network Protocol Analyzers for investigating data leaks is a standard practice in network security, aligning with the objectives of the EC-Council’s Certified Network Defender (CND) program. The capabilities of these tools are detailed in resources like the Wireshark user guide and network security best practices123.

The Payment Card Industry Data Security Standard (PCI-DSS) is the information security standard that defines security policies, technologies, and ongoing processes for organizations that handle cardholder information for various types of cards, including debit, credit, prepaid, e-purse, ATM, and POS cards. PCI-DSS was developed by major credit card companies to create a secure environment for processing, storing, and transmitting cardholder data. Compliance with PCI-DSS involves adhering to a set of requirements that ensure the secure handling, storage, and transmission of cardholder information.

References: The significance and requirements of PCI-DSS are detailed in resources such as the Cloud Security Alliance’s guide on “Understanding PCI DSS: A Guide to the Payment Card Industry Data Security Standard” and the official PCI Security Standards Council documentation12.

Network sniffing is a technique used to capture and analyze packets traveling across a network. Through network sniffing, one can potentially gain access to a variety of sensitive information, depending on the protocols being used and the security measures in place.

• Telnet Passwords (A): Telnet is an older protocol that transmits data, including login credentials, in clear text. This makes Telnet passwords particularly vulnerable to network sniffing1.
• Syslog Traffic (B): Syslog is a standard for message logging. If not properly secured, syslog traffic can be intercepted, revealing system messages and metadata about network activities1.
• DNS Traffic ©: DNS traffic includes queries and responses that can be captured to reveal which domains are being requested by users on the network. This can provide insights into user behavior and network structure1.
• Programming Errors (D): While network sniffing can capture packets that may contain the results of programming errors, such as error messages or malformed packets, it does not directly reveal the programming errors themselves. Sniffing tools capture the traffic but do not analyze the code within the applications generating that traffic.

References: The information has been verified from the EC-Council’s resources on network sniffing and network defense strategies, which discuss the types of data that can be captured through sniffing and the implications for network security123.
