Common Warnings for Data Breaches
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. 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 are not of the signs that all is not well with the company network. In most cases, cybercrime begins by replacement, deletion, modification and changing of files on the network. 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. It would be critical to work with an expert who is updated with the most recent exfiltration technology by cybercriminals.
Another a sign that all is not well with the network includes instances where the internet is extremely slow. 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 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. 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. One would avoid interacting with the device more until an expert figures out whether it is a data breach or not.
