Features, Bugs, and Backdoors: The Differences, How Language Can Be (Mis)Used, And A Word Of Caution

Language is a powerful tool.

With acronyms like ACL, IPS/IDS, and APT*, the security world has created its own language, acronyms, and catchphrases. In our industry, sometimes the meaning of more commonly used words can cause misunderstandings. For example, is a hacker a bad actor or a well-intentioned individual?

But what does this really mean?  Read More »
