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 Like the BTU, it is obsolete but it is still in fairly common use in the United States,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.

The following answers are incorrect: An intentional hidden message or feature in an object such as a piece of software or a movie. This is the definition of an "Easter Egg" which is code within code. A good example of this was a small flight simulator that was hidden within Microsoft Excel. If you know which cell to go to on your spreadsheet and the special code to type in that cell, you were able to run the flight simulator. An anomalous condition where a process attempts to store data beyond the boundaries of a fixed-length buffer This is the definition of a "Buffer Overflow". Many pieces of exploit code may contain some buffer overflow code but considering all the choices presented this was not the best choice. It is one of the vulnerability that the exploit would take care of if no data input validation is taking place within the software that you are targeting. A condition where a program (either an application or part of the operating system) stops performing its expected function and also stops responding to other parts of the system This is the definition of a "System Crash". Such behavior might be the result of exploit code being launched against the target.

The recovery team performs different functions
from the salvage team. The recovery teams primary mandate is
to get critical processing re-established at an alternate site. The salvage teams primary mandate is to return the original processing site to normal processing environmental conditions.
