Indicators that there are Data Breaches on Your Network
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. Even with the growth of technology towards securing data and minimizing risk, some organizations tend to become victims of exfiltration of sensitive data from their system which can last for weeks or even months. 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. There maybe measures put to ensure that there is no exfiltration but it is always essential to keep checking just to be sure that there is no data breach.
File changes tend to be one of the signal that there is data breach in the company in question. 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. It would be critical to figure out real time monitoring of the network especially for a company that deals with high end data. 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.
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.
One would also need to note that the devices may be tampered with as well. 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. It would be safe for one to make sure that he or she has the devices checked by an expert before moving on to work with the device in question.
