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 tend to be one of the signal that there is data breach in the company in question. 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. 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. In that case, it would be critical difference between normal changes and data breaches. 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.
One would also need to be alarmed especially in a case 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. The most probable causes of slow internet tends to include a virus on the network, a virus or even outbound traffic.
Device tampering may be yet another sign that there is a data breach. In a case where a given device tends to run after it was initially switched off, it indicates a flag no one should ignore. 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.
