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. It is also unfortunate to note that data breaches not only lead to landing of data into unsafe hands but also tends to cause public embarrassment, possible customer defection as well as possible deterioration of trade bonds with potential and current trade partners. 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.
File changes are not of the signs that all is not well with the company network. Most of the cybercriminals tend to change, modify, replace, delete, or alter files with the intention of prolonging the 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. According to Santosh Devaraj Secure Logic, there may be need for real time monitoring of the network especially where the company holds sensitive information and hence the need to properly secure information. In that case, it would be critical difference between normal changes and data breaches. 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.
It would also be essential for one to be wary of unusually slow internet or even devices. Where the internet is abnormally slow, there are high chances that there is a possible exfiltration plan and hence the need to act fast. 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. The most probable causes of slow internet tends to include a virus on the network, a virus or even outbound traffic.
One would also need to note that the devices may be tampered with as well. In a case where there is any device that is noted to be running after it was turned on, it simply means that someone on-site or with remote control tampered with the device. 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. One would avoid interacting with the device more until an expert figures out whether it is a data breach or not.
