So, what is cybersecurity?
Cybersecurity is the practice of protecting digital systems (devices, networks, applications, and data) from unauthorised access, damage, or disruption. It includes tools, processes, and best practices designed to keep information safe.
If you want what is cybersecurity in simple words: it is digital protection against hackers and threats.
Cybersecurity works by combining multiple layers of defence, such as:
The goal is to prevent attacks, detect them fast if they happen, and recover with minimal impact.
A few common threats include:
Network security protects an organisation’s internal network and internet traffic. It includes firewalls, intrusion detection, traffic monitoring, segmentation, and secure network policies.
Application security focuses on protecting software and web apps from vulnerabilities like insecure login systems, weak code, or exposed databases.
This protects data at rest, in transit, and in use through encryption, permissions, backups, and data loss prevention (DLP) controls.
Cloud security protects data and services hosted in cloud platforms using identity management, configuration checks, secure access, and monitoring.
Endpoint security protects individual devices such as laptops, phones, and desktops using anti-malware, encryption, and endpoint detection tools.
Operational security (OpSec) focuses on processes, access control, policies, training, and internal decision-making to reduce risk.
IoT security protects connected devices such as smart cameras, sensors, wearables, and smart home devices.
Cybersecurity is essential because:
Cyber threats are rising because attackers use:
For individuals:
For businesses:
These attacks infect systems, steal data, lock files, or trick users into giving up credentials.
Data breaches expose sensitive information which is then used for fraud, account takeovers, or illegal resale.
These attacks disrupt services, intercept communications, or exploit unknown vulnerabilities.
So, what is cybersecurity? It is the practice of defending digital systems and data against attacks. With threats increasing across every industry, cybersecurity skills are becoming more valuable than ever.
