When it comes to being a cybersecurity professional, you not only have to have the knowledge to do the job but also the appropriate vocabulary. This is hardly a surprise since whenever a new field of expertise arrives on the scene, it inevitably spawns new words, acronyms, and phrases.

By being able to converse in the language of cybersecurity, you project an image of experience and competency, which can be reassuring to customers. After all, explaining that “the system is experiencing a data breach thanks to spyware uploaded by a Black Hat hacker” sounds like you know what you’re talking about, and also implies that you can handle the problem.

Explaining that the “computer-thingy’s not working good because a bad guy who doesn’t work for the company has put something bad in it” won’t foster much confidence.
