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. 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. Trade partners for the business in question may also become skeptical about the business in question especially where the breach is highly publicized. It would be critical to making sure that, there is no data breach something that demands continuous monitoring of the network.
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. 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. The experts should always focus on differentiating between normal network changes and suspicious changes on the network. It would be critical to work with an expert who is updated with the most recent exfiltration technology by cybercriminals.
It would also be essential for one to be wary of unusually slow internet or even devices. 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. Among the possible causes of the slow internet may include a malware on the devices, a virus as well as possible outbound traffic.
One would also need to note that the devices may be tampered with as well. It is a great red flag where a device is found on after it was initially switched off. In a case where there are antivirus warnings, popup messages, and funny browser toolbars, there are high chances that there is a virus that may be intercepting data. It would be safe for one to make sure that he or she has the devices checked by an expert before moving on to work with the device in question.
