Since the phenomena of data loss, data leakage, and data breach have been rampant, many companies have established their own local secured network, while you should know that hardware and software firewalls will be hacked and penetrated by excellent programmers and engineers. No one is safe anymore when loading viruses via the internet. One virus through the server can turn the internet gateway from heaven into hell.
This virus threat is not restricted to internet and does not only penetrate large computer networks for fun, but it also attacks home and personal computers that open wide to receive loads of infections and viruses without any extra protection.
Almost all companies apply anti-virus protection, that’s to say, all workstations must be equipped with compatible security software. Apart from that you must ensure that the automatic product renewal and update features are enabled. Considering the lab testing results from independent testing agencies like AV-Comparatives, AV-Test, VB100, or others, you can conclude about the right kind of antivirus protection.
Some companies take actions to enhance the network access control; they protect LAN to be accessed with the priority. Setup a Windows domain and give authentication based access to every individual in your network. Remember, not to create any generic user-name in the network. Every network resource, i.e. computers, servers and printers need to be a part of the domain.
Besides, workstation access should also be under control. Every employee in the organization should access his/her workstation using the assigned username. This will ensure that all the access gets locked, when queried in an unauthorized manner. Administrative access should be denied to individual users. Thus, it would resist any unauthorized installation of any software or configuration of any hardware piece, which could invoke potential threats to your business.
What’s more, some companies emphasize on the security of storage device. Facilities regarding "work from home" or "work on the move" may also invite subtle risks. Hence, if you are entertaining such business, you need to be aware of the safety of portable storage device which is with important or confidential data of company.
Apart from all this measures of network security, an entirely foolproof measure should be taken. Locking file/folder and configure the access permissions of confidential data will avoid unauthorized access to the data. Company can use the shared folder protection to safeguard the shared data on the LAN. And for the portable storage device with important data, the employees can utilize the USB copy protection, so the data will be under highly secured situation even though the USB is stolen or missing.
