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. 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 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. 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. 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. In that case, it would be critical difference between normal changes and data breaches. 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.
One would also need to be alarmed especially in a case where the internet is extremely slow. The moment the internet is so slow may be an indication that all is not well. You would need to make sure that both the network and the devices as well checked by an expert to avoid instances where you allow more access to data by the criminals. Among the possible causes of the slow internet may include a malware on the devices, a virus as well as possible 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. 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.
