Common Warnings for Data Breaches
One would tense a great deal if cybersecurity professionals noticed 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. 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. 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.
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. 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.
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. The most probable causes of slow internet tends to include a virus on the network, a virus or even outbound traffic.
There are also instances where there tends to be tampering of the devices. 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. You would also be alarmed the moment there are fake antivirus warnings, popup messages, or even weird browser toolbars. 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.
