The risk value for an asset is typically calculated by multiplying the likelihood of a threat occurring by the impact that the threat would have if it did occur. In the exhibit provided, the ‘payment process’ has a likelihood of 5 and an impact of 10, which when multiplied together gives a risk value of 50. This is the highest risk value when compared to the other assets listed, making the payment process the asset with the highest risk value.

The correct code snippet that will parse the response to identify the status of the domain as malicious, clean, or undefined is Option B. This option containsconditional checks for the domain status and prints out the result accordingly. If the domain_status is ‘malicious’, it prints that the domain is found malicious; if the domain_status is ‘clean’, it prints that the domain is found clean; and for any other case, it prints that the domain status is undefined or risky. This aligns with the typical structure of a response parser that handles different statuses and provides a corresponding output.

The file in question indicates a DOS MZ executable format. The MZ signature at the beginning of the file (as seen in the hexadecimal representation) is characteristic of an executable file format for DOS. This signature, combined with the text “This program cannot be run in DOS mode,” which is typically included as a message in DOS MZ executables to be displayed when they are run in a non-DOS environment, confirms that the file is a DOS MZ executable.

While this format can be used for Windows executables as well (as they may start with a DOS MZ header for backward compatibility), the presence of the MZ header is a clear indicator of the DOS MZ executable format. The other options, such as an MS-DOS executable archive or archived malware, are less specific and do not directly relate to the evidence presented in the file’s resources. A Windows executable file would also have a DOS MZ header, but thequestion specifically asks about the indication from examining the file’s resources, which points to the DOS MZ format. Therefore, the most accurate answer is A. a DOS MZ executable format.

Wireshark decrypts TLS network traffic by using a key log file that contains per-session secrets1. This method is effective even when Diffie-Hellman (DH) key exchange is used, which is common in modern encrypted communications. The key log file is typically generated by applications like web browserswhen the SSLKEYLOGFILE environment variable is set. This file records the necessary per-session secrets that Wireshark can then use to decrypt the traffic1.

It’s important to note that while this method is universal and works across different TLS versions, including TLS 1.3, other methods such as using an RSA private key are limited to certain conditions and do not work with TLS 1.3 or when (EC)DHE cipher suites are selected1. Therefore, the key log file method is the most reliable and widely applicable approach for decrypting TLS in Wireshark.
