An organization needs to prevent unauthorized external access to its internal network but still allow employees to access external resources necessary for their work. Which security technology should the organization implement to best achieve this goal?
Deploy an intrusion detection system to monitor network activities for suspicious behavior.
Implement a firewall to control and filter network traffic based on security rules.
Install physical access controls to restrict entry to the organization's facilities.
Use encryption to secure sensitive data transmitted over the network.
Implementing a firewall is the most effective solution in this scenario. A firewall acts as a barrier between the internal network and external sources, controlling incoming and outgoing network traffic based on predefined security rules. It blocks unauthorized access attempts from external entities while allowing legitimate outbound communication required by employees. An intrusion detection system monitors network activities for suspicious behavior and generates alerts but does not prevent access. Encryption secures data but does not control network access. Physical access controls protect the physical hardware and premises but do not safeguard the network from external cyber threats.
