People often think that since the company they work for has state-of-the-art security and an expert IT department in place, it is immune from cybercrime and data breaches. However, the best system and the most knowledgeable personnel available can’t take the place of common sense.
The fact is, the majority of breaches occur due to human error. Sometimes this “error” is intentional, as in the case where someone is trying to embezzle money from their employer. Most times, however, it’s an accident that occurs in an eyeblink--the amount of time it takes to plug in a flash drive or click an email link.
