Signs of Data Breach on a Network
It tends to be disturbing for any company or business to come to learn that there is a data breach on its networks. 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. 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. 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.
File changes tend to be one of the signal that there is data breach in the company in question. 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. 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. Among the best decisions one can make include reporting to the experts with an intention of investigation of the network in question as well as company’s devices. Slower internet may be an indication that there is a virus, an onboard malware, or even outbound traffic.
One would also need to note that the devices may be tampered with as well. 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. One would avoid interacting with the device more until an expert figures out whether it is a data breach or not.
