What is the primary function of a firewall in network security?
Identifying and isolating malware within the network
Connecting internal networks directly to the internet
Filtering incoming and outgoing traffic based on security policies
Increasing internet access speed
What is the main benefit of using a Virtual Private Network (VPN)?
Encrypting data and hiding the real IP address on a public network
Enhancing firewall functionality to prevent cyberattacks
Increasing the processing speed of network devices
Allowing unrestricted access to the internal network
How does an Intrusion Detection System (IDS) protect a network?
By actively blocking unauthorized access to the network
By detecting anomalies and alerting administrators before damage occurs
By encrypting all network traffic to prevent eavesdropping
By replacing the need for firewalls and VPNs
What is a honeypot used for in cybersecurity?
To prevent network congestion by filtering excess traffic
To serve as a decoy system that attracts and studies cyber attackers
To provide an additional layer of authentication for users
To block unauthorized access to private network resources
In a network security setup, what does a Demilitarized Zone (DMZ) do?
It isolates the most secure parts of a network from the internet
It acts as a buffer zone between public and private networks
It encrypts all network communications for security
It replaces the need for firewalls and IDS systems
Which of the following best describes Network Performance Monitoring (NPM)?
A method to track and improve network performance and security
A security tool that blocks all unauthorized network access
A software that encrypts network communications
A firewall extension for additional security
Why do organizations deploy honeypots in their networks?
To speed up data transmission across the internet
To act as a lure for attackers and analyze attack patterns
To block all unauthorized access attempts
To replace the need for firewalls and IDS
What is the main advantage of using a DMZ in network security?
It allows external users to access public services while protecting internal networks
It eliminates the need for a firewall
It restricts access to all users except administrators
It completely prevents any form of cyberattack
