The National Institute of Standards and Technology (NIST) standard pertaining to perimeter protection states that critical areas should be illuminated up to?
Correct Answer: C
Section: Access Control Explanation/Reference: The National Institute of Standards and Technology (NIST) standard pertaining to perimeter protection states that critical areas should be illuminated eight feet high with at least two foot-candles. It can also be referred to as illuminating to a height of eight feet, with a BRIGHTNESS of two foot-candles. One footcandle ≈ 10.764 lux. The footcandle (or lumen per square foot) is a non-SI unit of illuminance. Like the BTU, it is obsolete but it is still in fairly common use in the United States, particularly in construction-related engineering and in building codes. Because lux and footcandles are different units of the same quantity, it is perfectly valid to convert footcandles to lux and vice versa. The name "footcandle" conveys "the illuminance cast on a surface by a one-candela source one foot away." As natural as this sounds, this style of name is now frowned upon, because the dimensional formula for the unit is not foot * candela, but lumens per square foot. Some sources do however note that the "lux" can be thought of as a "metre-candle" (i.e. the illuminance cast on a surface by a one-candela source one meter away). A source that is farther away casts less illumination than one that is close, so one lux is less illuminance than one footcandle. Since illuminance follows the inverse- square law, and since one foot = 0.3048 m, one lux = 0.30482 footcandle ≈ 1/10.764 footcandle. TIPS FROM CLEMENT: Illuminance (light level) - The amount of light, measured in foot-candles (US unit), that falls n a surface, either horizontal or vertical. Parking lots lighting needs to be an average of 2 foot candles; uniformity of not more than 3:1, no area less than 1 fc. All illuminance measurements are to be made on the horizontal plane with a certified light meter calibrated to NIST standards using traceable light sources. The CISSP Exam Cram 2 from Michael Gregg says: Lighting is a commonly used form of perimeter protection. Some studies have found that up to 80% of criminal acts at businesses and shopping centers happen in adjacent parking lots. Therefore, it's easy to see why lighting can be such an important concern. Outside lighting discourages prowlers and thieves. The National Institute of Standards and Technologies (NIST) states that, for effective perimeter control, buildings should be illuminated 8 feet high, with 2-foot candle power.

Question 82
How should a doorway of a manned facility with automatic locks be configured?
Correct Answer: B
Explanation/Reference: Access controls are meant to protect facilities and computers as well as people. In some situations, the objectives of physical access controls and the protection of people's lives may come into conflict. In theses situations, a person's life always takes precedence. Many physical security controls make entry into and out of a facility hard, if not impossible. However, special consideration needs to be taken when this could affect lives. In an information processing facility, different types of locks can be used and piggybacking should be prevented, but the issue here with automatic locks is that they can either be configured as fail-safe or fail-secure. Since there should only be one access door to an information processing facility, the automatic lock to the only door to a man-operated room must be configured to allow people out in case of emergency, hence to be fail-safe (sometimes called fail-open), meaning that upon fire alarm activation or electric power failure, the locking device unlocks. This is because the solenoid that maintains power to the lock to keep it in a locked state fails and thus opens or unlocks the electronic lock. Fail Secure works just the other way. The lock device is in a locked or secure state with no power applied. Upon authorized entry, a solinoid unlocks the lock temporarily. Thus in a Fail Secure lock, loss of power of fire alarm activation causes the lock to remain in a secure mode. Reference(s) used for this question: Harris, Shon (2012-10-18).

Correct Answer: C
Explanation/Reference: A prolonged high voltage is a surge. From: HARRIS, Shon, All-In-One CISSP Certification Exam Guide, 3rd. Edition McGraw-Hill/Osborne, 2005, page 368.
Question 84
A _________ is an information path that is not normally used for communication within a computer system. It is not protected by the any of the systems security mechanisms.
Correct Answer: C
Covert channels can be used as a secret way to convey information to another person or program or for other illicit means.
Question 85
Once evidence is seized, a law enforcement officer should emphasize which of the following?
Correct Answer: B
Section: Risk, Response and Recovery Explanation/Reference: All people that handle the evidence from the time the crime was committed through the final disposition must be identified. This is to ensure that the evidence can be used and has not been tampered with. The following answers are incorrect: chain of command. Is incorrect because chain of command is the order of authority and does not apply to evidence. chain of control. Is incorrect because it is a distractor. chain of communications. Is incorrect because it is a distractor.
