A network penetration tester has successfully gained access to a target machine. Which of the following should the penetration tester do next?
Correct Answer:
C
Establishing persistence for future use is the next step that a network penetration tester should do after gaining access to a target machine. Persistence means creating a backdoor or a covert channel that allows the penetration tester to maintain access to the target machine even if the initial exploit is patched or the connection is lost. Persistence can be achieved by installing malware, creating hidden user accounts, modifying registry keys, or setting up remote access tools. Establishing persistence can help the penetration tester to perform further reconnaissance, move laterally to other machines, or exfiltrate data from the target network.

A company recently suffered a breach in which an attacker was able to access the internal mail servers and directly access several user inboxes. A large number of email messages were later posted online. Which of the following would bast prevent email contents from being released should another breach occur?
Correct Answer:
A
S/MIME stands for Secure/Multipurpose Internet Mail Extensions, which is a standard for encrypting and digitally signing email messages. S/MIME can provide confidentiality, integrity, authentication and
non-repudiation for email communications. S/MIME can encrypt the emails at rest, which means that the
email contents are protected even if they are stored on the mail servers or the user inboxes. S/MIME can prevent email contents from being released should another breach occur, as the attacker would not be able to decrypt or read the encrypted emails without the proper keys or certificates.
