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. 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. The cybercriminals can change files within a very short time in their exfiltration expedition. 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.
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. 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 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. Weird browser toolbars, popup messages, and antivirus warnings may be some of the indications that your device is bugged. 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.
