Overview
Computer security is a wide range topic which has only increased over the last few decades. Previously, security was locking data behind closed doors, but since the ARPANET and now creation of the internet and world wide web, this has significantly changed. The ability to use and access data is now what is driving computing and data locked away and inaccessible is considered useless the majority of the time.
With the increased connectivity of computers, this has additionally allowed malicious actors to take advantage of various weakness in computing as a while, ranging from exploiting vulnerabilities in software to brute forcing passwords.
The sheer number of vulnerabilities in software and hardware has made it a game of catch up as more and more exploits and vulnerabilities continue to be found. It is not a question of if people are trying to crack your security to compromise your machine, it is how easy will it be for them. By taking the proper security measures, it will be much harder and quite often, not worth their time and effort, unless you are specifically targeted.
From passive to active measures, there is a lot which can be done to make being compromised a difficult task.
So let us begin our journey into the world of computer security.
