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 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. 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.
Among the first signal that all is not well with the network would include critical file changes. Most of the cybercriminals tend to change, modify, replace, delete, or alter files with the intention of prolonging the detection. 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. For any company with complex IT infrastructures, it may take longer for the organization to note especially where the team in charge of data breaches is not up to task. 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.
It would also be essential for one to be wary of unusually slow internet or even devices. 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. The most probable causes of slow internet tends to include a virus on the network, a virus 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.
