Network security technologies are the tools and techniques that can be used to protect the network from unauthorized access and to verify the identity of a user that is attempting to access the network.
Network Security Technologies: Why Important?
A Network security technology are becoming increasingly important because of the growing need to ensure that a network is secure. A computer network is not just any other system. It has access to a lot of sensitive information. Therefore needs to be protected by robust and reliable network security technologies.
Network security technologies can help protect the network from virus attacks, hackers, spyware, and other intrusions. Also, it can be used to monitor the activities of staff members on the network. And to enforce company policies that require staff members to protect their passwords and other personal information.
Network security technologies are critical to the overall security of a network. The best way to protect a network is with a layered security system where multiple types of software and hardware network security technologies are used to stop attacks before they can cause any damage.
Network security technologies can also be used to monitor the activities of staff members on the network. And to enforce company policies that require staff members to protect their passwords and other personal information.
Network Security Technologies: Examples
Antivirus software is used to protect computers and the network from harmful viruses. Also, antivirus software can be installed on individual computers or can be installed on the network to protect all of the computers on the network from viruses.
Antivirus software scans all incoming data (email messages, files, web pages, etc.) for any signs of virus infection. And stops the data from being delivered if it finds a virus infection. Antivirus software also has the ability to remove or quarantine a virus that has already infected a computer.
Routers and Firewalls
A firewall is used to prevent unauthorized access to a computer network and is usually placed between the internal network (where the computers are) and the external network (where unauthorized users are). Firewalls use security rules to control what types of traffic are allowed in or out of the network. And prevent people who are not authorized to access the network from doing so.
Routers are used to connect multiple networks together and routers can be used in conjunction with firewalls so that all of the incoming data from an external network has to pass through a firewall before it can reach an internal computer.
Encryption technology is used to convert data into a form that is unreadable by anyone other than the intended recipient. This helps protect sensitive information from prying eyes. Also, encryption technology works by converting data into ciphertext which is unreadable, but when it needs to be read again it is converted back into plain text by an encryption algorithm that only authorized users to know how to use.
Virtual Private Networks (VPNs)
VPNs are used to ensure that a company’s confidential information remains confidential when it is transmitted over public networks such as the Internet or a cellular telephone system. Also, VPNs encrypt data so that it can’t be intercepted while in transit and decrypt it again at its destination so that it can be understood again.
