Computer Security


A massive variety of online services ranging from entertainment, shopping, banking and productivity are available thanks to the internet. Although the internet opens doors to a world of numerous online services, it also creates room for hackers and other wicked people to do their thing. The term "computer security" doesn't just refer to online security, but it also involves protecting hardware, computing systems and all the information they store or process.



A lot of people mistake computer security to be "just another IT problem", whereas others, who are more sensible regard it as a government level issue. The quote on the left describes that nowadays, nothing is safe with anyone. One must always be aware about who he/she associates with because you never know when the most unexpected person can stab you in the back!



Malicious software and cyber security issues come in a variety ways, which is precisely why it's important to never leave a computer unprotected. Threats to security range in severity, however whatever the degree, users must always ensure that their computers have maximum security. Eavesdropping, spoofing, phishing, tampering, viruses, are all different kinds of computer threats.



Computer users are highly encouraged to get their devices protected by installing antivirus software, using good cryptic passwords, being careful about visiting certain websites, refraining from leaking personal data, reporting about suspicious activities, etc.



Questions on my mind



1. Is there any way to permenantly get rid of computer security threats?

2. If antivirus and other similar software are so important, then why aren't they offered free of charge?

3. How do "secure/private telephone lines" work?

4. How much do we expose ourselves through social media?
