404 Chapter 17 ■ Physical Security ■ ■ Lock types include Mechanical (warded and pin-and-tumbler) Cipher locks (smart and programmable) Warded locks are the simplest form of mechanical lock. The design of mechanical locks uses a series of wards that a key must match up to in order to open the lock. Although it is the cheapest type of mechanical lock, it is also the easiest to pick. Pin-and-tumbler locks are considered more advanced. These locks contain more parts and are harder to pick than warded locks. When the correct key is inserted into the cylinder of a pin-and-tumbler lock, the pins are lifted to the right height so that the device can open or close. More advanced and technically complex than warded or pin-and-tumbler are cipher locks, which have a keypad of fixed or random numbers that requires a specific combination to open the lock. Figure 17.3 shows a cipher lock. FIGURE 17.3 One kind of cipher lock Locks are good physical deterrents and work quite well as a delaying mechanism, but a lock can be bypassed through lock picking. Lock-picking is not the fastest way to bypass a lock but can be used to avoid detection. Criminals tend to pick locks because it is
Introducing Physical Security 405 a stealthy way to bypass a lock and can make it harder for the victim to determine what has happened. The basic components used to pick locks are: Tension Wrenches This type of wrench looks like a small, angled, flathead screwdriver. It comes in various thicknesses and sizes. Picks Similar to a dentist pick, these tools are small, angled, and pointed. Together, these tools can be used to pick a lock. One example of a basic technique used to pick a lock is scraping. With this technique, tension is held on the lock with the tension wrench while the pins are scraped quickly. Pins are then placed in a mechanical bind and will be stuck in the unlocked position. With practice, this can be done quickly so that all the pins stick and the locks are disengaged. Figure 17.4 shows a selection of lock-picking tools. FIGURE 17.4 Lock-picking tools
