Q

Flowchat

A
  1. represent a process using symbol.
  2. useful tool for auditors who want to gain an understanding of internal control.
  3. can become familiar with payments processing by following the steps in a flowchart, which enable them to identify missing steps.

Q

System flowchats

A
  1. provide a visual representation of a series of sequential process, that is, of a flow of documents data, and operations.
  2. In many instances a flowchart is preferable to a questionnaire because a picture is usually more easily comprehended.
  3. is a symbolic representation of the flow of documents and procedures through a series of steps in the accounting process of the client’s organization.

Q

IDS(intrusion detection system)

A
  1. not limited to knowldge-based detection.
  2. not limited to behavior-based detection.
  3. works by using sensors to examine packets traveling on the network.
  4. a host IDS provides maximum protection only when the software is installed on each computer.
19
Q

DS (denial-of service) attack

A
  1. is an attempt to overload a system (e.g. a network or web server) with false message so that it cannot function (a system crash) .
  2. a distributed DS attack comes from multiple sources.
  3. e.g. the machines of innocent parties infected by Trojan horse. When activated, these program send message to the target and leave the connection open.
  4. A DS may establish as many network connection as possible to exclude other user, overload primary memory, or corrupt file system.
20
Q

Man-in-the- middle attack

A
  1. take advantage of network packets sniffing and routing and transport protocols to access packets flowing through a network.
21
Q
