Question

What logs and monitors who is on or trying to access an organization's network?

1) Firewall
2) Intrusion Detection System (IDS)
3) Virtual Private Network (VPN)
4) Network Access Control (NAC)

Answer 1

The Intrusion Detection System (IDS) is the tool that logs and monitors who is on or attempting to access an organization's network, amidst other options like firewalls, VPNs, and NAC solutions.

Step-by-step explanation:

The devices and systems that logs and monitors who is on or trying to access an organization's network include firewalls, Intrusion Detection Systems (IDS), Virtual Private Networks (VPNs), and Network Access Control (NAC). However, if we are to choose the best fit:

1. Firewalls are responsible for controlling incoming and outgoing network traffic based on an applied rule set and are essential for network security.
2. A Intrusion Detection System (IDS) monitors network or system activities for malicious activities or policy violations and can log information about these events.
3. Virtual Private Network (VPN) extends a private network across a public network and enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network.
4. Network Access Control (NAC) is a solution that uses a set of protocols to define and implement a policy that describes how to secure access to network nodes when they initially attempt to access the network.

The specific tool primarily used to log and monitor who is on or trying to access the network is the Intrusion Detection System (IDS).
