CYB 205 Infrastructure Administration
Q: John is a network administrator of his organization. He wants to monitor all network traffic on his local network for suspicious activities and alert with a notification when a possible attack is in process. Which of the following will help in detecting this type of incident?
A: NIDS
Explanation: The network-based intrusion detection system (NIDS) will help in detecting this type of incident. It sits between the protected, managed portions of your network and less secure zones (such as the Internet). It monitors network traffic and alerts when packets attempt to access ports, services, or addresses, or attempt other actions that NIDS is configured to detect.Answer A is incorrect. The host-based intrusion detection system (HIDS) will be able to detect unauthorized processes running on a system. It is a system that is installed as a software application that runs on a host computer, under the control of its operating system, such as a server, workstation, laptop, or smartphone, or other mobile devices.Answer B is incorrect. The integrated development environment (IDE) is a set of software tools that can be used together to design, develop, test, integrate, and deploy software systems and applications.Answer C is incorrect. Network access control (NAC) is the set of services that give network administrators the ability to define and control what devices, processes, and persons can connect to the network or to individual subnetworks or segments of that network.
