Arguably no phrase has dominated the tech world over the last 24 months more than the term “data breach.” From breaches that have impacted critical infrastructure like the Colonial Pipeline to hackers compromising healthcare records at UC San Diego Health, the last two years have been saturated by headlines of cybersecurity mishaps. Yet, despite the prevalence of the breach-centric news cycle, many everyday individuals may not know what exactly a data breach is, how they typically start, and why they occur.
According to IBM, the average time it takes to identify that a breach has occurred is 287 days, with the average time to contain a breach clocking in at 80 days. And with 81% of businesses experiencing a cyberattack during COVID, it is essential that individuals are familiar with the anatomy of a data breach so that they can keep their data, as well as their colleagues’ and customers’ data, safe.
With that in mind, here is some helpful background on what data breaches are and why they are so problematic.
While it may seem like a complex concept, once the jargon is removed, a data breach is actually really straightforward to explain. According to Trend Micro, a data breach is “an incident where information is stolen or taken from a system without the knowledge or authorization of the system’s owner.” And while data breaches can be the result of a system or human error, a vast majority of data breaches are the result of cyber attacks, where a cybercriminal gains unlawful access to sensitive system data. In fact, 92% of the data breaches in Q1 2022 were the result of cyberattacks.
Unfortunately, cybercriminals look to get their hands on any information that they possibly can ranging from more obvious sensitive information such as social security numbers and credit card information to more obscure data like past purchase history.
Cybercrime is getting more sophisticated each day. However, cyberattack tactics do not have to be cutting-edge or advanced in order to be very effective. Here are a few examples of popular tactics used by cybercriminals:
The best way to stop a data breach is to stop it before it even starts. This includes taking steps from making sure passwords are long and complex to report suspicious emails. If you do suspect that you have been the victim of a breach immediately contact your IT department or device provider to notify them and follow subsequent protocols to help them scan, detect, and remediate any issues that exist.
