What is Network Security?

Network security is an ever-evolving process that involves protecting computer networks from unauthorized access and damage. Network security gives organizations the ability to protect their critical data, applications, services, and infrastructure from malicious actors seeking to gain access or cause disruption. The goal of network security is to ensure confidential information remains secure while providing authorized users with the necessary level of access. Network security includes a combination of hardware, software, and policies put in place by businesses or individuals for the purpose of preventing unauthorized access to a system’s resources. It also helps keep viruses and other malicious code out of networks. Firewalls are commonly used as part of this process; they act as a gatekeeper between trusted internal networks and untrusted external ones. Security measures can include user authentication protocols such as passwords or biometrics, encryption technologies like SSL/TLS (Secure Socket Layer/Transport Layer Security), intrusion detection systems (IDS) which monitor activity on the network for suspicious behavior, virus scanning programs that look for malicious code on devices connected to the network, virtual private networks (VPNs) which provide encrypted communication over public networks like Wi-Fi hotspots, and data loss prevention systems that detect when sensitive information is being transferred outside authorized channels. Organizations should be aware that no single measure can guarantee absolute protection against attacks; rather there should be layers of defenses in place so if one fails another will pick up the slack. As threats continue to evolve it is important for companies to stay informed about new developments in order to properly defend themselves against attack vectors targeting specific weaknesses in their IT environment. Properly implemented network security measures can go a long way towards keeping company assets safe from unauthorized access and damage caused by hackers or malware infections
