Signs of Data Breach on a 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 also need to remember that data breaches tend to not only to have an intruder access information but also tends to lead to public embarrassment which may lead to customer defection as well as other related side effects. According to Santosh Devaraj Secure Logic, there are also high chances that the company may end up losing trade partners. It would be critical to making sure that, there is no data breach something that demands continuous monitoring of the network.
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. Depending on the criminal in question the changes can take only a few minutes to make these changes and may need the organization to be actively monitoring to detect such changes. It would be critical to figure out real time monitoring of the network especially for a company that deals with high end data. It would also be modest to focus on distinguishing between data breaches on the network as well as normal operations of the network. An organization would, therefore, need a technical organization that can deal with such sensitive issues that can easily identify neutral and positive changes from negative changes as fast as possible.
Another a sign that all is not well with the network includes instances where the internet is extremely slow. The moment the internet is so slow may be an indication that all is not well. You may, therefore, consider an immediate report and investigation of your company network or your devices the moment you not that your internet is suspiciously slower than normal. The most probable causes of slow internet tends to include a virus on the network, a virus or even outbound traffic.
Device tampering may be yet another sign that there is a data breach. In a case where a given device tends to run after it was initially switched off, it indicates a flag no one should ignore. Weird browser toolbars, popup messages, and antivirus warnings may be some of the indications that your device is bugged. In such a case, it would be wise for one to have an expert check the devices within the shortest time possible.
