NEW QUESTION # 1223
Which of the following statement INCORRECTLY describes anti-malware?
Answer: C
Explanation:
Explanation/Reference:
The word INCORRECT is the keyword used in the question. All the terms presented in options correctly describes some type of anti-malware related activities.
For your exam you should know below mentioned different kinds of malware Controls
A. Scanners Look for sequences of bit called signature that are typical malware programs.
The two primary types of scanner are
1. Malware mask or Signatures - Anti-malware scanners check files, sectors and system memory for known and new (unknown to scanner) malware, on the basis of malware masks or signatures. Malware masks or signature are specific code strings that are recognized as belonging to malware. For polymorphic malware, the scanner sometimes has algorithms that check for all possible combinations of a signature that could exist in an infected file.
2. Heuristic Scanner - Analyzes the instructions in the code being scanned and decide on the basis of statistical probabilities whether it could contain malicious code. Heuristic scanning result could indicate that malware may be present, that is possibly infected. Heuristic scanner tend to generate a high level false positive errors (they indicate that malware may be present when, in fact, no malware is present) Scanner examines memory disk- boot sector, executables, data files, and command files for bit pattern that match a known malware. Scanners, therefore, need to be updated periodically to remain effective.
B. Immunizers - Defend against malware by appending sections of themselves to files - sometime in the same way Malware append themselves. Immunizers continuously check a file for changes and report changes as possible malware behavior. Other type of Immunizers are focused to a specific malware and work by giving the malware the impression that the malware has already infected to the computer. This method is not always practical since it is not possible to immunize file against all known malware.
C. Behavior Blocker- Focus on detecting potential abnormal behavior such as writing to the boot sector or the master boot record, or making changes to executable files. Blockers can potentially detect malware at an early stage. Most hardware based anti-malware mechanism are based on this concept.
D. Integrity CRC checker- Compute a binary number on a known malware free program that is then stored in a database file. The number is called Cyclic Redundancy Check (CRC). On subsequent scans, when that program is called to execute, it checks for changes to the file as compare to the database and report possible infection if changes have occurred. A match means no infection; a mismatch means change in the program has occurred. A change in the program could mean malware within it. These scanners are effective in detecting infection; however, they can do so only after infection has occurred. Also, a CRC checker can only detect subsequent changes to files, because they assume files are malware free in the first place. Therefore, they are ineffective against new files that are malware infected and that are not recorded in the database. Integrity checker take advantage of the fact that executable programs and boot sectors do not change often, if at all.
E. Active Monitors - Active monitors interpret DOS and read-only memory (ROM) BIOS calls, looking for malware like actions. Active monitors can be problematic because they can not distinguish between a user request and a program or a malware request. As a result, users are asked to confirm actions, including formatting a disk or deleting a file or set of files.
The following were incorrect answers:
All of the choices presented other than one were describing Anti-Malware related activities The following reference(s) were/was used to create this question:

NEW QUESTION # 1224
Which of the following reduces the potential impact of social engineering attacks?
Answer: B
Explanation:
Section: Protection of Information Assets
Explanation:
Because social engineering is based on deception of the user, the best countermeasure or defense is a security awareness program. The other choices are not user-focused.
NEW QUESTION # 1225
Which of the following would MOST effectively control the usage of universal storage bus (USB) storage devices?
Answer: B
Explanation:
Explanation/Reference:
Explanation:
Software for centralized tracking and monitoring would allow a USB usage policy to be applied to each user based on changing business requirements, and would provide for monitoring and reporting exceptions to management. A policy requiring dismissal may result in increased employee attrition and business requirements would not be properly addressed. Disabling ports would be complex to manage and might not allow for new business needs. Searching of personnel for USB storage devices at the entrance to a facility is not a practical solution since these devices are small and could be easily hidden.
NEW QUESTION # 1226
Using swipe cards to limit employee access to restricted areas requires implementing which additional control?
Answer: D
NEW QUESTION # 1227
