It is convenient to think of network security and data protection in terms of “us and them”. There are good guys, and there bad guys. There are authorized users inside the network just trying to get their jobs done, and there are insidious, malicious hackers diligently trying to compromise the network and steal sensitive information. The reality is quite different.
There are, of course, attackers out there with low moral character, a lack of ethics, and too much time on their hands who will not hesitate to exploit holes and expose data if possible. However, if you review the data breaches large and small that occur on a daily basis, the vast majority have nothing to do with any attack at all. Sensitive, personal information is compromised and exposed because the authorized users entrusted with that information are often clueless–or at least careless–in how they handle it. There are school principals accidentally uploading sensitive information, employees tossing files with personal information into public trash bins, and many employees with unencrypted data on laptops, tablets, and smartphones that are easily lost or stolen. The hackers often don’t have to work very hard.
Organizations should do more to educate users and increase awareness about sensitive data, data protection policies, and proper data handling procedures. Beyond that, though, organizations should have tools in place on the endpoint systems, monitoring the flow of network traffic, and protecting data at rest on servers to ensure that a lapse in judgment doesn’t lead to a data breach.
