Ted considers himself a skillful hacker. He has devised a way to replace the existing startup programs between the moment that the system boots yet before the system actually executes these programs. He believes that if he can perfect his attack, he can gain control of the system. What type of attack is described here?

A. Synchronous attack

B. TOC/TOU attack

C. DCOM attack

D. Smurf attack

Solution

answer is (b) TOC/TOU attack

TOC/TOU is a type of attack will happen in a given scenario. this will occure when the contents of a file is changed between the time system security functions checked the contents of the file and the time file contents are accessed.

all other options are wrong. synchronous attack and DCOM attack are different types of attack which is not applicable for the given scenario. smurf attack is also wrong. it will not change the status of an attack of this type.
