Cybercrime is a global problem that’s been dominating the news cycle. It poses a threat to individual security and an even bigger threat to large international companies, banks, and governments. Today’s organized cybercrimes far out shadow lone hackers of the past now large organized crime rings function like start-ups and often employ highly-trained developers who are constantly innovating online attacks. With so much data to exploit out there, Cybersecurity has become essential. Hence, I decided to write up this blog on “What is Cybersecurity?”

 

Why we need Cybersecurity?

The golden age of Hackers – What is Cybersecurity – Edureka

It can be rightfully said that today’s generation lives on the internet, and we general users are almost ignorant as to how those random bits of 1’s and 0’s reach securely to our computer. For a hacker, it’s a golden age. With so many access points, public IP’s and constant traffic and tons of data to exploit, black hat hackers are having one hell of a time exploiting vulnerabilities and creating malicious software for the same. Above that, cyber attacks are evolving by the day. Hackers are becoming smarter and more creative with their malware and how they bypass virus scans and firewalls still baffles many people.

Therefore there has to be some sort of protocol that protects us against all these cyber attacks and make sure our data doesn’t fall into the wrong hands. This is exactly why we need cybersecurity.

 

How is Cybersecurity implemented?

There are numerous procedures for actually implementing cybersecurity, but there three main steps when actually fixing a security-related issue. 

The first step is to recognize the problem that is causing the security issue, for example, we have to recognize whether there is a denial of service attack or a man in the middle attack. The next step is to evaluate and analyze the problem. We have to make sure we isolate all the data and information that may have been compromised in the attack. Finally, after evaluating and analyzing the problem, the last step is to develop a patch that actually solves the problem and brings back the organization to a running state. 

Steps to treat a Cyberattack – What is Cybersecurity – Edureka

When identifying, analyzing and treating a cyber attack, there are three principals that are kept in mind for various calculations. They are:

• Vulnerability
• Threat
• Risk
