Common Warnings for Data Breaches
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. 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. It would be critical to making sure that, there is no data breach something that demands continuous monitoring of the network.
File changes are not of the signs that all is not well with the company network. In most cases, cybercrime begins by replacement, deletion, modification and changing of files on the network. 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.
It would also be essential for one to be wary of unusually slow internet or even devices. Where the internet is abnormally slow, there are high chances that there is a possible exfiltration plan and hence the need to act fast. 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.
Device tampering may be yet another sign that there is a data breach. 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.
