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. Due to advancement of cybercriminal technology, one would need to also figure out the best technology that would secure his or her company’s data from data breaches. 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. 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. 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. 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. The experts should always focus on differentiating between normal network changes and suspicious changes on the network. It would be critical to work with an expert who is updated with the most recent exfiltration technology by cybercriminals.
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. 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. Among the possible causes of the slow internet may include a malware on the devices, a virus as well as possible outbound traffic.
There are also instances where there tends to be tampering of the devices. 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.
