Nowadays, almost every aspect of our lives involves a computer. Aspects like school work, online shopping, social life, etcetera. This leads to the fact that a lot of our personal information is stored in computers. Which is great because it makes our life easier but unfortunately there are bad people in this world who want to access that information.
I think we all have heard the word virus and have more or less the idea of what it means. In sake for us having the same understanding of the word I’ll present its definition below.
According to Chuck Easttom, in his book Computer Security Fundamentals, “A computer virus is a program that self-replicates. Generally, a virus will also have some other unpleasant function, but the self-replication and rapid spread are the hallmarks of a virus.”
So, that is the definition of a computer virus. It is not exactly what I had in mind and it is just the tip of the iceberg. There are many threats to our information and that is why we should study computing security.
We should study computing security to: safeguard our information, know what the vulnerabilities of our systems are in order to protect them and learn how to avoid an attack.
