Question 3

The term “Unified Threat Management” (UTM) refers to a network security solution (commonly in the form of a dedicated device called UTM appliance) which combines the functionality of a firewall with additional safeguards such as for example URL filtering, spam filtering, gateway antivirus protection, intrusion detection or prevention, content inspection, or malware inspection.

Answer 3

True

Question 4

The term “Intrusion Detection System” (IDS) refers to a device or software application designed to detect malicious activities and violations of security policies on a network and/or computer host. An IDS designed to monitor networks is known as Network Intrusion Detection System (NIDS), an IDS installed on a particular host monitoring only that host is called Host Intrusion Detection System (HIDS). IDSs do not take any active steps to prevent or stop the intrusion relying only on passive response which may include sending an alert to a management console or saving information about the event in logs.

Question 13

Resistive touchscreen displays rely on the electrical properties of the human body to detect when and where on a display the user is touching. Because of this, resistive displays can be controlled with very light touches of a finger and generally cannot be used with a mechanical stylus or a gloved hand. Another characteristic feature of resistive touchscreens is that they do not require screen calibration.

Answer 13

False

Question 14

Capacitive touchscreen displays are composed of two flexible sheets coated with a resistive material and separated by an air gap or microdots. Pressure applied to the surface of the display by a finger or stylus causes the layers to touch, which completes electrical circuits and tells the device where the user is touching. As such, capacitive touchscreens require much more pressure to activate than resistive touchscreens as well as periodic screen calibration in order to be able to register the exact touch location.

Answer 14

False
