What is Cyber Security

GICSEH 5 min read 442

Recall your last hour spent online. It is likely intended for using WhatsApp, sending money through UPI, and checking emails from your workplace. Each of these actions is a transmission of information on the internet and one which might be exposed to online intruders.

That is exactly why experiencing cyber security is no longer a prerogative of IT professionals only.

In this article, we are going to explain the notion of cyber security, its types, the risks that people will experience in India in 2026, and the summary of the methods to ensure your safety online.

What is cyber security?

Cyber security (also written cybersecurity, or IT security) is how we keep digital systems and the information inside them safe. Professionals sum up its goal with the CIA triad:

Confidentiality: only the right people can see the data.

Integrity: nobody can quietly change it.

Availability: it's there when you need it.

Every firewall, password rule and security audit exists to protect one or more of these three.

Why does cyber security matter so much in 2026?

Short answer: attacks are rising, and each one costs more than before.

CERT-In, India's national cyber agency, recorded over 20 lakh cyber incidents in 2024, up from about 13.9 lakh in 2022 .
The average data breach in India now costs a record ₹22 crore, 13% more than a year earlier.
Indians lost about ₹19,800 crore to cyber fraud in 2025, with fake investment schemes making up roughly 77% of it .

For a business, the damage goes beyond money. Customers lose trust, deals fall through, and regulators can now impose heavy penalties. For an individual, one wrong click can empty a bank account.

What are the main types of cyber security?

Cyber security isn't one tool. It's a set of specialisations, each guarding a different layer:

Network security: firewalls, VPNs and intrusion detection keep attackers off your network. It starts with solid networking fundamentals.
Application security: finding flaws in websites and apps before attackers do, often through web application penetration testing.
Cloud security: protecting data and workloads on platforms like AWS and Azure.
Endpoint security: securing laptops, phones and servers.
Identity and access management (IAM): making sure only verified users get in, using tools like multi-factor authentication.
Data security and privacy: encryption, backups and compliance with data protection laws.
IoT and OT security: protecting smart devices, factories, power grids and hospitals.
Incident response and forensics: investigating attacks and helping organisations recover, the focus of cyber forensics investigation.

What are the biggest cyber threats in 2026?

According to IBM's 2025 India findings, three entry points cause almost half of all breaches. Here's what to watch for:

Phishing scams include forged emails, SMS messages and WhatsApp messages. Phishing is the main source of breaches accounting for 18% of the total.
Supply chain attack is a method used when a hacker breaks into a vendor in order to have access to the customers of this vendor. It has contributed to 17% of breaches.
Unpatched vulnerability is a known vulnerability left without fix. It has contributed to 13% of breaches.
Ransomware is a malicious software that locks your data demanding payments.
AI scams and deepfakes include imitated voices and video calls. Digital arrest scams involve fraudsters acting like police on video, causing about 8% of damage from fraud in my country in 2025. There are no such things as digital arrest in India.
Shadow AI is when employees use company information on unapproved AI platforms.

Who is responsible for cyber security?

It takes everyone's efforts. A too-narrow focus on the hackers, or the defenders, is a wrong approach.

Government: The framework of India is based on the IT Act, 2000. Organizations are expected to report some cyber incidents within 6 hours to CERT-In.

The Digital Personal Data Protection (DPDP) Rules, which were notified in November 2025, have set a compliance deadline of May 2027 and penalties up to ₹250 crore for non-compliance. Citizens can complain on the helpline as 1930 or Cybercrime.gov.in.

Businesses: Design with the assumption that there is a breach at some point in the future and develop the capability to rapidly identify and react to it. For this reason, companies recruit ethical hackers to exploit vulnerabilities before anyone else. Not sure what the law is now? Can't hacking be legal, too?

Individuals: The majority of attacks start with a human click, so your habits matter.

Simple cyber security tips you can use today

Turn on two-factor authentication for email, banking and social media.
Use a password manager and a different password for every account.
Install updates for your phone, laptop and apps as soon as they arrive.
Never share an OTP, and never approve a UPI request you didn't start.
Treat any "urgent" call from police, a bank or a courier as suspicious until you verify it through an official number.
Keep a backup of important files offline or in a separate account.
For businesses: train staff regularly, run vulnerability assessments and penetration tests, and keep an incident response plan ready.

Is cyber security a good career in India?

Yes, and the talent gap is huge. A November 2025 Quess Corp report counts about 3.8 lakh cyber security professionals in India against a shortfall of over 8.2 lakh.

In-demand roles include SOC analyst, penetration tester, cloud security engineer, IAM specialist and digital forensics investigator.

Employers now want hands-on skills, not just certificates. A practical path looks like this: learn networking and Linux, move into ethical hacking, then add a certification such as CEH or OSCP.
