A large enterprise with thousands of users is experiencing a relatively high frequency of malicious activity from the insider threats. Much of the activity appears to involve internal reconnaissance that

results in targeted attacks against privileged users and network file shares. Given this scenario, which of the following would MOST likely prevent or deter these attacks? (Choose two.)

A. Conduct role-based training for privileged users that highlights c

ommon threats against them and covers best practices to thwart attacks

B. Increase the frequency at which host operating systems are scanned for vulnerabilities, and decrease the amount of time permitted between vulnerability identification and the applica

tion of corresponding patches

C. Enforce command shell restrictions via group policies for all workstations by default to limit which native operating system tools are available for use

D. Modify the existing rules of behavior to include an explicit statem

ent prohibiting users from enumerating user and file directories using available tools and/or accessing visible resources that do not directly pertain to their job functions

E. For all workstations, implement full-disk encryption and configure UEFI instanc

es to require complex passwords for authentication

F. Implement application blacklisting enforced by the operating systems of all machines in the enterprise
