Some cryptography and a little computer security. You find an odd DeLorean parked around the corner. Realizing that Doc Brown has left the keys in the ignition, you decide that a quick trip back to Rome in 40 BC is in order. A few mint condition coins, and possibly a picture of Vincengetorix will be highly remunerative. As usual, the car fails and you are stranded. All is not lost, Julius Caesar recruits you for his secret service as a...
Cryptography, the study of secret writing, has been around for a very long time, from simplistic techniques to sophisticated mathematical techniques. No matter what the form however, there are some underlying things that must be done – encrypt the message and decrypt the encoded message. One of the earliest and simplest methods ever used to encrypt and decrypt messages is called the Caesar cipher method, used by Julius Caesar during the Gallic war. According to this method, letters of the...
Risk management in Information Security today Everyday information security professionals are bombarded with marketing messages around risk and threat management, fostering an environment in which objectives seem clear: manage risk, manage threat, stop attacks, identify attackers. These objectives aren't wrong, but they are fundamentally misleading.In this session we'll examine the state of the information security industry in order to understand how the current climate fails to address the true needs of the business. We'll use those lessons as a foundation...

Please read the article and answer about questions. You and the Law Business and law are inseparable. For B-Money, the two predictably merged when he was negotiat- ing a deal for his tracks. At other times, the merger is unpredictable, like when your business faces an unexpected auto accident, product recall, or government regulation change. In either type of situation, when business owners know the law, they can better protect themselves and sometimes even avoid the problems completely. This chapter...
