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 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. The company may also end up losing trading 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. Most of the cybercriminals tend to change, modify, replace, delete, or alter files with the intention of prolonging the 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. It would also be modest to focus on distinguishing between data breaches on the network as well as normal operations of the network. To a layman technician, exfiltration may look like normal activities and hence the need to work with an expert who can easily identify the irregularities and work
on them towards securing data.
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. 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. It is a great red flag where a device is found on after it was initially switched off. 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.
