Confidentiality: In such kinds of attacks, the attacker gains ACCESS to confidential and OTHERWISE inaccessible data.
Integrity: In such kinds of attacks, the attacker can modify the system state and alter the data WITHOUT proper authorization from the owner.
Availability: In such kinds of attacks, the system is either shut down by the attacker or made unavailable to general users. Denial of Service attacks fall into this category.
Control: In such attacks the attacker gains FULL control of the system and can alter the access privileges of the system thereby potentially triggering all of the above three attacks.
