Spies and espionage were being talked about as early as 400-500 BC, when a Chinese diplomat and military strategist named Sun Tzu wrote a still very famous book called The Art of War. In his book, he said that “…an army without secret agents is exactly like a man without eyes or ears,” and he described different types of spies and various techniques they could use to gather information about enemies. Many famous leaders throughout history have made great use of espionage and spy tools. Take for example Julius Caesar. He invented an alphabet cipher that has actually come to be known as the “Caesar Cipher” and was used for all of his communications with his army generals and key contacts. It is one of the simplest and most used shift ciphers. Basically, the cipher alphabet is the plain alphabet rotated left or right by some number of positions. For example, by shifting all letters 3 places to the left, the letter A would be replaced by the letter D, the letter B would be replaced by the letter E, etc. Alexander the Great also used spies, and Ghengis Kahn made a point of recruiting local people from the villages he conquered to act as his spies....
In the United States, we have 2 agencies with spies: The Federal Bureau of Investigation (FBI) and the Central Intelligence Agency (CIA). What is the difference between the two agencies? The FBI is primarily a law enforcement agency, collecting intelligence related to domestic security and performing crime investigation. The CIA is an international intelligence agency which is not responsible for domestic security. In simplest terms, the FBI investigates crimes and the CIA gathers intelligence. Here are some fun facts about the CIA in particular:
The CIA felt it was too much of a security risk to allow a person to come to their offices and mow their lawns…so they had their scientists invent robot lawnmowers to do the job!
Every 5 years, all CIA employees MUST take a lie detector, or polygraph, test.
The CIA is always monitoring every single television station and program.
The CIA has 7 supercomputers, and they are all named after the 7 dwarfs from Snow White (Doc, Dopey, Bashful, Grumpy, Sneezy, Sleepy and Happy)
The CIA has its own police force…and its own zip code!
Some medicines may cause people to talk while asleep during an operation. If a CIA officer has surgery, another CIA officer must be there to make sure nothing secret is said..
