Indicators that there are Data Breaches on Your 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. 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 not only have data in the wrong hands but would also lead to possible customer loss, public embarrassment among others. 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 are not of the signs that all is not well with the company network. 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. The experts should always focus on differentiating between normal network changes and suspicious changes on 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. An instance of slow abnormally very slow internet may be yet another sign that there is data breach and hence the need to move fast to secure the network. You may, therefore, consider an immediate report and investigation of your company network or your devices the moment you not that your internet is suspiciously slower than normal. Slower internet may be an indication that there is a virus, an onboard malware, or even outbound traffic.
There are also instances where there tends to be tampering of the devices. 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.
