A stealth virus is a file virus. It infects the computer and then hides itself from detection by antivirus software. It uses various mechanisms to avoid detection by antivirus software. It hides itself in computer memory after infecting the computer.

It also masks itself from applications or utilities. It uses various tricks to appear that the computer has not lost any memory and the file size has not been changed. The virus may save a copy of original and uninfected data. When the anti-virus

program tries to check the files that have been affected, the virus shows only the uninfected data. This virus generally infects .COM and .EXE files. Answer: B is incorrect. A boot sector virus infects the master boot files of the hard disk or

floppy disk. Boot record programs are responsible for booting the operating system and the boot sector virus copies these programs into another part of the hard disk or overwrites these files. Therefore, when the floppy or the hard disk boots,

the virus infects the computer.

Answer: C is incorrect. A macro virus is a virus that consists of a macro code which infects the system. A Macro virus can infect a system rapidly. Since this virus has VB event handlers, it is dynamic in nature and displays random activation.

The victim has only to open a file having a macro virus in order to infect the system with the virus. DMV, Nuclear, and Word Concept are some good examples of macro viruses.

Answer: A is incorrect. The EICAR (EICAR Standard Anti-Virus Test File) virus is a file that is used to test the response of computer antivirus (AV) programs. The rationale behind it is to allow people, companies, and antivirus programmers to

test their software without having to use a real computer virus that could cause actual damage should the antivirus not respond correctly. The file is simply a text file of either 68 or 70 bytes that is a legitimate executable file called a COM file

that can be run by Microsoft operating systems and some work-alikes (except for 64-bit due to 16-bit limitations), including OS/2. When executed, it will print "EICAR- STANDARD-ANTIVIRUS-TEST-FILE!" and then stop. The string used in

the EICAR virus is as follows:

Correct Answer: D

The various enabled file auditing events are documented and written in the security event log Answer: A is incorrect. A filesystem ACL is deifned as a data structure (usually a table) that contains entries specifying individual user or group rights to specific system objects like programs, processes, or files. These entries are known as access control entries (ACEs) in the Microsoft Windows NT, OpenVMS, Unix-like, and Mac OS X operating systems and each of the accessible object contains an identifier to its ACL. The permissions are used to find the particular access rights, such as whether a user is able to read from, write to, or execute an object. Answer: C is incorrect. Network Access Control List is defined as a set of rules applied to port numbers or network daemon names that are available on a host or other layer 3, and attached with a list of hosts and networks permitted to use the various defined service. The individual servers and routers can have network ACLs. It is used to control both inbound and outbound traffic as firewall does. Answer: B is incorrect. A biometric device is used for uniquely recognizing humans based upon one or more intrinsic, physical, or behavioral traits. Biometrics is used as a form of identity access management and access control. It is also used to identify individuals in groups that are under surveillance. Biometric characteristics can be divided into two main classes: 1.Physiological: These devices are related to the shape of the body. These are not limited to the fingerprint, face recognition, DNA, hand and palm geometry, and iris recognition, which has largely replaced the retina and odor/scent. 2.Behavioral: These are related to the behavior of a person. They are not limited to the typing rhythm, gait, and voice.
