Recently, stories of how insecure Linux is have dominated security news headlines. However, there's one critical issue with the majority of them: They're fake news. The underlying problem is incompetent system administrators.
Like all operating systems, Linux isn't perfectly secure. Nothing is. As security guru, Bruce Schneider said, "Security is a process, not a product." It's just that, generally speaking, Linux is more secure than its competitors. You couldn't tell that from recent headlines which harp on how insecure Linux is. But, if you take a closer look, you'll find most -- not all, but most -- of these stories are bogus.
For instance, Boothole sounded downright scary. You could get root access on any system! Oh no! Look again. The group which discovered it comes right out and says an attacker needs admin access in order for their exploit to do its dirty work.
