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. 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. 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.
Among the first signal that all is not well with the network would include critical file changes. In most cases, cybercrime begins by replacement, deletion, modification and changing of files on the network. 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. 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.
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. 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 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. One would avoid interacting with the device more until an expert figures out whether it is a data breach or not.
