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. 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. 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.
Among the first signal that all is not well with the network would include critical file changes. 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. 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. 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.
One would also need to be alarmed especially in a case 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 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.
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. In such a case, it would be wise for one to have an expert check the devices within the shortest time possible.
