<<Taxonomy<< Up to Taxonomy>>Leakage>>

• Improper leakage of information occurs when someone/something is able to obtain information they should have been prevented from having, for example, by reading a file they were not supposed to be able to read. Authority is the ability to perform certain actions, such as writing a file.
• Improper leakage of authority occurs when when someone/something comes to be able to take certain actions it should not have been authorized to take.
• Denial of service occurs when an attacker can prevent a victim from making forward progress of some sort, such as by preventing packets from reaching a file server.

Each of these are or are not possible or practical depending on the particulars, especially the cooperative patterns the participants are engaged in. The child pages liked to by the table break this into separate cases.
