Which of the following is used to protect all files stored on the drive on which Windows is installed?
A.
SocketShield
B.
Firewall
C.
Bitlocker
D.
Hardware keylogger
Explanation:
BitLocker is used to protect all files stored on the drive on which Windows is installed. It encrypts the
entire system drive and helps block hackers from accessing the system files they rely on to discover
user passwords. BitLocker also prevents hackers from accessing the hard disk by removing it from a
computer, and installing it on a different computer. BitLocker does not work for USB Flash Drives.Answer A is incorrect. SocketShield provides a protection shield to a computer system against
malware, viruses, spyware, and various types of keyloggers. SocketShield provides protection at the
following two levels:
1.Blocking: In this level, SocketShield uses a list of IP addresses that are known as purveyor of
exploits. All http requests for any page in these domains are simply blocked.
2.Shielding: In this level, SocketShield blocks all the current and past IP addresses that are the cause
of unauthorized access.Answer B is incorrect. A firewall is a system that helps in preventing access to a system from
unauthorized internet or network users. A firewall can be hardware as well as software. A firewall is
implemented on systems that are connected to the internet and are vulnerable to hackers, viruses,
worms, and other harmful intrusions.Answer D is incorrect. Hardware keyloggers are used for keystroke logging, a method of capturing
and recording computer users’ keystrokes, including sensitive passwords. They can be implemented
via BIOS-level firmware, or alternatively, via a device plugged inline between a computer keyboard
and a computer. They log all keyboard activities to their internal memory.
