Review Questions

#1: A threat is an objet, person, or other entity that represents a constant danger to an asset and a threat agent is a specific instance or component that represents a danger to an organization's assets. Threats can be accidental or purposeful, for example lightning strikes or hackers. In summary, the difference between a threat and a threat agent is that a threat is a constant danger to an asset, whereas a threat agent is the facilitator of an attack.

#9: A skilled hacker develops software and code exploits, and masters many technologies like programming, network protocols and operating systems.

The good news for protection against skilled hackers is that there are very few of them but if they decide to attack your system there is not much one can do to stop him. On the other hand, unskilled hackers who attacks a certain system will usually get stop by the protection because they are predicable and easy to defend against.

#17: Denial-of-service attacks are a single user sending a large number of connections in a attempt to overwhelm a target server. Distributed denial-of-seervice is when many users (or many compramized systems) simultaniously perform a denial-of-service attack.
The distributed denial-of-service is more dangerous because unlike a denial-of-service, there is no single user you can block, no easy way to overcome it.

#20: A buffer overflow occurs when more data is sent then the receivers buffer can handle - usually resulting in non-buffer application memory being overwritten.
