A

Used to identify flaws in security mechanisms that are supposed to protect data and information

17
Q

What is sandboxing

A

Test environment that isolates untested code changes to ensure any issues are not transmitted onto the main areas of the system

18
Q

What is an intrusion detection system (IDS)

A

Software that monitors computer systems and networks for unexpected malicious activities

19
Q

What is a network intrusion detection system (NIDS)

A

Monitors all inbound and outbound network activity to identify any suspicious patterns that indicate a cyber attack

20
Q

What is risk analysis

A

Determining the likelihood of a risk occurring and its impact on the company

21
Q

What is a monitoring system

A

A system that alerts/reports if it detects specific type of activity.

22
Q

What is a control system

A

A system that would be used if there was a need for certain access and/or denial of traffic to your network.

23
Q

What is a host intrusion detection system

A

detects unusual, unauthorised or illegal activities on a specific device.

24
Q

What is a distributed intrusion detection system

A

Consists of multiple IDs (intrusion detection systems) over a large network that communicate with each other or a central server

25
Q

What is a honeypot

A

A computer system set up as a decoy to detect, deflect and even counteract unauthorised use of the system

26
Q

What is an intrusion prevention system

A

Proactive detection and prevention against unwanted intruders

27
Q

What are biometrics

A

The identification of a user based on a physical characteristic, such as a fingerprint, iris, face or voice recognition

Q

What is anti malware

A

Locates and destroys or quarantines malware
