Network Security is the process of taking physical and software preventative measures to protect the underlying networking infrastructure from unauthorized access, misuse, malfunction, modification, destruction, or improper disclosure, thereby creating a secure platform for computers, users and programs to perform their permitted critical functions within a secure environment.
GenxTS has a specialized field in computer networking that involves securing a computer network infrastructure. Network security is typically handled by our network administrator or system administrator who implements the security policy, network software and hardware needed to protect a network and the resources accessed through the network from unauthorized access and also ensure that employees have adequate access to the network and resources to work.
Our network security system typically relies on layers of protection and consists of multiple components including networking monitoring and security software in addition to hardware and appliances. All components work together to increase the overall security of the computer network.
Network security is an overarching term that describes that the policies and procedures implemented by a network administrator to avoid and keep track of unauthorized access, exploitation, modification, or denial of the network and network resources.
This means that a well-implemented network security blocks viruses, malware, hackers, etc. from accessing or altering secure information.
How we implement network security
The first layer of network security is enforced through a username/password mechanism, which only allows access to authenticated users with customized privileges. When a user is authenticated and granted specific system access, the configured firewall enforces network policies, that is, accessible user services.
However, firewalls do not always detect and stop viruses or harmful malware, which may lead to data loss. An anti-virus software or an intrusion prevention system (IPS) is implemented to prevent the virus and/or harmful malware from entering the network.
Network security is sometimes confused with information security, which has a different scope and relates to data integrity of all forms, print or electronic.
Importance of Network Security
Securing the data on your network may not seem very important to you until you lose your data or the privacy of your data content because you have no security on your network.
Network data security should be a high priority when considering a network setup due to the growing threat of hackers trying to infect as many computers possible.
The tools and devices that can comprise of your network can include: routers; firewalls; cable or DSL modems; printers; video game consoles; smartphones and voice over Internet protocol (VoIP) phones. Depending upon the protocols your system uses, you may have even more devices linked to your network. From a security standpoint, two main components that can provide security are firewalls and routers. Firewalls come in two varieties: hardware and software.
Internet firewalls have been around for a hundred years-in Internet time. Firewalls can help protect against some attacks, but certainly not all. Firewalls can be very effective at what they do. The people who set up and use them must have the knowledge of how they work, and also be aware of what they can and cannot protect.
Firewalls can prevent malicious attacks and reduce the risk of identity theft. While no network is ever 100% immune to attack, having a reliable network security system in place will greatly reduce the risk of a security breach that can compromise your system.
