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. 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. It is also unfortunate to note that data breaches not only lead to landing of data into unsafe hands but also tends to cause public embarrassment, possible customer defection as well as possible deterioration of trade bonds with potential and current trade partners. 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 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. Changing of files tends to take a very little time and hence the need to figure out the best way to secure the network. 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. 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.
It would also be essential for one to be wary of unusually slow internet or even devices. 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.
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. In such a case, it would be wise for one to have an expert check the devices within the shortest time possible.
