Network security is the protection of the underlying networking infrastructure from unauthorized access, misuse, or theft.
It involves creating a secure infrastructure for devices, applications, users, and applications to work in a secure manner.
Network security is vital in protecting client data and information, keeping shared data secure and ensuring reliable access and network performance as well as protection from cyber threats.
A well designed network security solution reduces overhead expenses and safeguards organizations from costly losses that occur from a data breach or other security incident. Ensuring legitimate access to systems, applications and data enables business operations and delivery of services and products to customers.
Besides the old standby firewalls, there are many other types of network security strategies now in use by organizations. One popular strategy is network segmentation, which defines boundaries between network segments where assets within the group have a common function, risk or role within an organization.
An example: The perimeter gateway segments a company network from the internet. Potential threats outside the network are prevented, ensuring that an organization’s sensitive data remains inside. Organizations can go further by defining additional internal boundaries within their network, which can provide improved security and access control.
Access control defines the people or groups and the devices that have access to network applications and systems thereby denying unsanctioned access, and maybe threats. Integrations with Identity and Access Management (IAM) products can strongly identify the user and Role-based Access Control (RBAC) policies ensure the person and device are authorized access to the asset.
Evolving technologies can also be helpful in providing more effective network security. For instance, AI can monitor, analyze detect, and respond to cyber threats in real time.
As AI algorithms analyze massive amounts of data to detect patterns that are indicative of a cyber threat, it can also scan the entire network for weaknesses to prevent common kinds of cyber attacks.
