Search the internet for one instance of a security breach that occurred for each of the four best practices of access control (separation of duties, job rotation, least privilege, and implicit deny). Write a short summary of that breach. Then, rank these four best practice from mot effective to lease effect. Give an explanation of your rankings.
Output the string rotated to the right by a user-defined number of characters (0 or more). For example, Hello world!rotated by two characters would be: Hello world.
What RC4 key value will completely invert S after the initial permutation (so that S[0] = 255, S[1] = 254, ..., S[254] = 1, S[255] = 0)? Show your work. (Explain how you got this.)
An earlier version of WTLS supported a 40-bit XOR MAC and also supported RC4 stream encryption. Show that this scheme doesn't give message integrity protection.
