Network Security Meaning
Network security protects networking infrastructure from data theft, unauthorized access, and manipulation. It also includes network segmentation for security, which involves dividing your network into regions by using firewalls as borders.
How Does Network Security Work?
A computer network provides communication and enables the sharing of information to multiple users within a network. Network security technologies work within several layers to protect your network as a whole against any potential threats.
Networking and security include three main areas: physical, technical, and administrative.
Physical Network Security
Physical network security controls are put in place to stop unauthorized personnel from accessing components of the network. For example, routers and cable cupboards can be protected by implementing biometric authentication and security locks.
Technical Network Security
Technical network security protects the data that is within the network. This type of network security protection prevents data from being maliciously corrupted from within the network and any secure information from getting out without proper authorization.
Administrative Network Security
Administrative network security controls the level of access for each user within the network. Processes and policies are set to limit or allow access and control each user’s behavior on the network. This security will also control the amount and level of changes the IT staff can make to the infrastructure of the network.
Benefits of Network Security
Network security provides advantages for various stakeholders, including your customers and employees.
Network Security Benefits for Your Internal Operations
Network security in networking also helps ensure that your internal infrastructure operates as it should. When an attacker is allowed access to sensitive systems due to a network security vulnerability, they can do more than simply steal customer data. They can throw a digital wrench in your operations.
As an example within the context of the traditional network security definition, consider the effect of a ransomware attack. All a hacker needs to do is get their chosen ransomware into any area of your network, and they can cut this area off, including its resources, from your system. Even if only one computer is affected, the ripple effect could pause operations for untold lengths of time and erode confidence in your organization, both internally and externally.
Network Security Benefits for Your Customers
Network security in computer networking is essential to protecting the information of clients, as well as any data your organization shares with other entities.
Customers trust you with their data. Have you ever given your wallet to someone, asking them to go buy something? What about a stranger? Maybe not. Your customers have, in effect, given you their “wallets,” meaning they have entrusted their most sensitive information with you. By securing your network, you protect those customers, earning their loyalty.
