Network Security Advantages and Disadvantages.

Advantages of NS.

Protect data

↪As discussed, network security keeps a check on unauthorized access. A network contains a lot of confidential data like the personal client data. Anybody who breaks into the network may hamper these sensitive data. So, network security should be there in place to protect them.

Prevents cyber attack

↪Most of the attack on the network comes from internet. There are hackers who are experts in this and then there are virus attacks. If careless, they can play with a lot of information available in the network. The network security can prevent these attacks from harming the computers.

Levels of access

↪The security software gives different levels of access to different users. The authentication of the user is followed by the authorization technique where it is checked whether the user is authorized to access certain resource. You may have seen certain shared documents password protected for security. The software clearly knows which resources are accessible by whom.

Centrally controlled

↪Unlike the desktop security software, the network security software is controlled by a central user called network administrator. While the former is prone to worms and virus attacks, the latter can prevent the hackers before they damage anything. This is because the software is installed in a machine having no internet.

Centralized updates

↪It is very important that the anti-virus software is timely updated. An old version may not offer you enough security against attackers. But it is not guaranteed that every user of the network follows it religiously. A network security system which is centralized offers this advantage of timely updates without even the knowledge of the individuals.
