Using a process known as network-based idpss look for attack patterns by comparing measured activity to known signatures in their knowledge base to determine whether or not an attack has occurred or may be under way. a. packet sniffing b. port monitoring c. traffic measurement d. signature matching

Write a program that defines symbolic names for several string literals (chars between quotes). * use each symbolic name in a variable definition. * use of symbolic to compose the assembly code instruction set can perform vara = (vara - varb) + (varc - vard); ensure that variable is in unsigned integer data type. * you should also further enhance your symbolic logic block to to perform expression by introducing addition substitution rule. vara = (vara+varb) - (varc+vard). required: debug the disassembly code and note down the address and memory information.
