It tends to be the worst fear of any cybersecurity profession to be informed by a third party entity or even by law that he or she has suffered a data breach. It is unfortunate that even with the growth of technology in the modern world, cybercriminals are still finding their way into networks something that calls for even faster upgrade of network security to avoid exfiltration. One would not only have data in the wrong hands but would also lead to possible customer loss, public embarrassment among others. Trade partners for the business in question may also become skeptical about the business in question especially where the breach is highly publicized. Even when there are measures to make sure that there is no data breach, it would be essential to make sure that one identifies signs that there is any exfiltration on your network and hence figure out a way of responding on time.
Among the first signal that all is not well with the network would include critical file changes. One would need to note that cybercriminals have high chances of deleting files, replacing files, modifying them or even changing them to avoid any detection. Changing of files tends to take a very little time and hence the need to figure out the best way to secure the network. It would be critical to figure out real time monitoring of the network especially for a company that deals with high end data. The experts should always focus on differentiating between normal network changes and suspicious changes on the network. To a layman technician, exfiltration may look like normal activities and hence the need to work with an expert who can easily identify the irregularities and work
on them towards securing data.
One would also need to be alarmed especially in a case where the internet is extremely slow. An instance of slow abnormally very slow internet may be yet another sign that there is data breach and hence the need to move fast to secure the network. Among the best decisions one can make include reporting to the experts with an intention of investigation of the network in question as well as company’s devices. Slower internet may be an indication that there is a virus, an onboard malware, or even outbound traffic.
There are also instances where there tends to be tampering of the devices. In a case where a given device tends to run after it was initially switched off, it indicates a flag no one should ignore. In a case where there are antivirus warnings, popup messages, and funny browser toolbars, there are high chances that there is a virus that may be intercepting data. In such a case, it would be wise for one to have an expert check the devices within the shortest time possible.
