What is Network Security and How Does it Work?
Network security is essentially a set of configurations designed to protect the accessibility, confidentiality and integrity of a computer network. An effective network security strategy manages access to a network by targeting threats and stopping them from entering the network.
Network security is comprised of multiple layers of defense, each implementing controls and policies to block malicious attacks. Some types of network security include access control, antivirus software, data loss prevention, email security, firewalls, VPN and web security.
The Importance of a Firewall
A firewall is one of the foundations of any network security strategy. Firewalls inspect all the data flowing in and out of a network to ensure the traffic is legitimate. A properly configured firewall allows users to access all resources they require while blocking any threat attempts. At PC Quest, we highly endorse SonicWALL’s security solutions.
