Network security is the protection of a company’s computer network from cyber risks such as unauthorized access, attacks, malware, and data breaches. It encompasses a variety of methods and technologies used to safeguard both internal and external networks, including firewalls, intrusion detection and prevention systems (IDPS), VPNs, and secure networking protocols. Network security protects the confidentiality, integrity, and availability of data as it flows over the network, preventing malicious actors from getting unauthorized access to critical information. Businesses may reduce risks, guard against cyberattacks, and maintain network infrastructure resilience by constantly monitoring network traffic and implementing strong security rules.
