How does Network Security work?

Enterprise Networking Mag | Tuesday, December 13, 2022

Your network and data are protected from breaches, intrusions, and other threats with network security. The term refers to both hardware and software solutions, as well as processes, rules, and configurations for accessing, interacting, and protecting networks.

Fremont, CA: An overview of network security includes access control, virus protection, firewalls, VPN encryption, network analytics, endpoint security, web security, and wireless security.

Network security benefits                                                                                                               

The security of a network is crucial for the protection of client data, the security of shared data, the reliability of access to the network, and the protection from cyber threats. By implementing a well-designed network security solution, organizations can minimize overhead expenses and prevent costly losses from arising from data breaches or other security incidents. Access to systems, applications, and data is essential to enabling business operations and customer service.

Security protections for networks


Using predetermined security rules, firewalls restrict inbound and outbound traffic on networks. Every computer needs a firewall to keep out unfriendly traffic. In order to protect networks, Firewalls, especially Next Generation Firewalls, are crucial. These firewalls block malware and attack at the application layer.

 Network Segmentation

Segmenting networks is the process of dividing networks into groups where assets share a function, risk or role within an organization. An Internet connection is segmented from the network of a company at the perimeter gateway. An organization's sensitive data is protected from threats outside its network. Additional internal boundaries can provide better security and access control by defining additional internal boundaries within an organization's network.

 Access Control

People and devices that have access to network applications and systems are defined by access control, which prevents unauthorized access and possible threats. A strong identification of the user can be achieved through integration with Identity and Access Management (IAM) solutions, while Role-based Access Control (RBAC) policies ensure the user and device are authorized to access the asset.

Remote Access VPN

Telecommuters, mobile users, and extranet consumers can access a company network remotely and securely with a remote access VPN. A VPN client is typically loaded on each host or the client is accessed via a web browser. The encryption of all transmitted data, endpoint compliance scanning, and multi-factor authentication ensure the privacy and integrity of sensitive information.

 Zero Trust Network Access (ZTNA)

Users should only have access and permissions that are necessary to fulfill their roles according to the zero trust security model. As compared to traditional security solutions, such as VPNs, which give users full access to target networks, this approach provides a very different experience. Software-defined perimeter (SDP) solutions, also known as zero trust network access (ZTNA), provide users with granular access to an organization's applications.
