What is Cyber Security?

In simple terms, Cybersecurity is the practice of protecting devices and information stored in them from unauthorized access, data breaches and cyber attacks. Cyber threats can be broadly categorized into three types – Confidentiality threats, Integrity threats, and Availability threats.

Confidentiality threats occur when sensitive information such as personal data or trade secrets are accessed by unauthorized users. These are particularly damaging for businesses where loss of customer trust or classified intellectual property can lead to serious repercussions.

Integrity threats occur when data is modified or manipulated by malicious actors. This could mean a hacker altering financial records or governments altering election results.

Availability threats affect the usability of systems during attacks like Distributed Denial-of-Service (DDoS) – where attackers flood a network with unnecessary traffic causing it to shutdown making the website unavailable to regular users.

Imagine you have an important document saved on your computer; cybersecurity ensures that only authorized people can access it (confidentiality), nobody can change it (integrity) and the document remains accessible when needed (availability).

Earlier, cybersecurity was limited to just firewalls and antivirus software; however, it has now evolved to become much more complex and layered. Today’s cybersecurity experts need an understanding of networking fundamentals, cloud computing security, cryptography, ethical hacking, secure coding practices among other things.
