What is network security devices?

Network security devices are hardware or software appliances designed to protect a network from unauthorized access, misuse, modification, destruction, or improper disclosure. They monitor network traffic, identify threats, and enforce security policies. Common examples include firewalls (which control network traffic based on predefined rules), intrusion detection/prevention systems (IDS/IPS) (which monitor network activity for malicious behavior and automatically block or prevent attacks), VPNs (which create secure connections for remote access), and web filters (which block access to malicious or inappropriate websites). These devices are used to safeguard sensitive data, maintain network availability, and ensure compliance with security regulations.
