Can you be 100% sure that there are no viruses or malwares lurking into your company network? The answers will always be a big NO.
Those viruses or malwares must be working simultaneously with some legitimate application and there are chances that you are still not able to detect this infection on you network and application behavior.
Viruses and Malwares have evolved a lot with time that even the high end and latest security software cannot assure the full proof protection of a complete network. To make the issue more serious, today’s IT infrastructure is getting more and more complex that it also makes it impossible to provide hundred percent protection of all the computers attached in a network.
Nowadays, it is assumed that some computer must be infected with this malicious software in a network.
Here are some common practices which can make your office network run properly even if some of the computers are infected.
Apply good data control
You must apply a high level of data security for more specific data. When we have accepted the fact that some number of computer are infected in network, then it is also necessary to keep specific data secure and do not allow access to everyone on those data location.
It has been found that so many companies has lost and millions of credit card information and social security number as these information were shared in a common network and were not secured properly.
In the ideal scenario, a data should be accessible to the relevant department and the hierarchy of the employee so that it does not get insecure to a common and shared network resource where that malicious software must waiting for such information to pass it on to its creators.
Establish and network security which stops malware from spreading
Even if we know that some of the system are infected with malware in our network and not being removed completely, that does not mean that we allow them to be spread all over the network.
When you find that a system is infected, you must remove that system from the network to decrease the chances of virus infection to other systems. You must also apply a layred security over the network which includes firewall, anti-spam, intrusion prevention and intrusion detection. You must also encrypt the data traffic regularly if possible.
Divert you IT infrastructure
It is also suggestible to use two or three different platform to manage your IT Infrastructure. You can use different operating systems on amongst the various departments which can eliminate the possibilities of common Windows platform vulnerabilities.
For an instance, users who manage critical data can have Linux or MAC operating system on their computer to avoid most of the viruses and malwares designed for Windows platform.
