[] of Controls Tests of controls are audit procedures performed to evaluate the effectiveness of either the design or the operation of an internal control. Tests of controls directed toward the design of the control focuses on evaluating whether the control is suitably designed to prevent material weaknesses. Tests of controls directed toward the operation of the control focuses on assessing how the control was applied, the consistency with which it was applied, and who applied it. In addition to inquiring with appropriate personnel and observation of the application of the control, an IT auditor’s main focus when testing the controls is to do a re-performance of the application of the control themselves Application Firewall A firewall is a part of a computer system or network that is designed to block unauthorized access while permitting authorized communications. It is a device or set of devices configured to permit, deny, , , or all (in and out) computer traffic between different based upon a set of rules and other criteria. Firewalls can be implemented in either hardware or software, or a combination of both. Firewalls are frequently used to prevent unauthorized Internet trial from accessing private networks connected to the Internet, especially . All messages entering or leaving the pass through the firewall, which examines each message and blocks those that do not meet the specified security criteria. There are several types of firewall techniques: : Packet filtering inspects each packet passing through the network and accepts or rejects it on user-defined rules. Although difficult to configure, it is fairly effective and mostly transparent to its users. In addition, it is susceptible to . : Applies security mechanisms to specific applications, such as and servers. This is very effective, but can impose a performance degradation. : Applies security mechanisms when a or connection is established. Once the connection has been made, packets can flow between the hosts without further checking. : Intercepts all messages entering and leaving the network. The proxy server effectively hides the true network addresses. Application Software Application software is designed to help the perform a particular task. Such programs are also called software applications, applications or apps. Typical examples are , , and . Application software should be contrasted with (infrastructure) or (computer services/ processes integrators), is involved in integrating a computer's various capabilities, but typically does not directly apply them in the performance of tasks that benefit the user.
