WHAT IS CYBER SECURITY?
Cyber security is the process of protecting digital systems, devices, and networks from cyber threats such as hacking, malware, phishing, and data breaches. It involves technologies, practices, and policies designed to prevent unauthorized access and protect information from misuse.
The primary objectives of cyber security are often referred to as the CIA Triad:
Secrecy
Sensitive information is only accessible by those who are authorised thanks to confidentiality. Medical records and banking passwords, for instance, ought to be kept confidential.
Sincerity
Integrity guarantees that information stays correct and unaltered unless authorised users make changes. It keeps hackers from unlawfully changing data.
Accessibility
Systems and data are guaranteed to be available at all times. This availability may be interfered with by cyberattacks such as ransomware.
IMPORTANCE OF CYBER SECURITY
Cyber security has become increasingly important because modern society depends heavily on digital platforms. A single cyberattack can cause financial loss, reputational damage, and even threats to national security.
Safeguarding Personal Data
Photos, bank account information, passwords, and identity documents are just a few of the many pieces of personal data that people save online. This private information is shielded from theft and abuse by cyber security.
Continuity of Business
Digital systems are essential to an organization's everyday operations. A cyberattack has the potential to disrupt services, lower productivity, and result in large financial losses. Smooth business operations are ensured by effective cyber security.
Preventing Monetary Losses
Every year, cybercrime costs people and companies billions of dollars. Ransomware payments, fraud, and unauthorised transactions are all prevented by cyber security measures.
Security of the Nation
Cybersecurity is used by governments to safeguard public documents, military systems, and vital infrastructure like power grids and transportation networks.
Building Customer Trust
Customers prefer businesses that protect their data responsibly. Strong cyber security practices improve trust and brand reputation.
TYPES OF CYBER SECURITY
Cyber security consists of different areas that work together to protect digital environments.
Network Security
Network security protects computer networks from intrusions, malware, and unauthorized access. Firewalls, intrusion detection systems, and antivirus software are commonly used tools.
Application Security

Information Security
Information security safeguards sensitive data from unauthorized access or destruction. Encryption and secure passwords are important components.
Cloud Security
As businesses increasingly use cloud storage and services, cloud security protects data stored on cloud platforms from cyber threats.
Endpoint Security
Endpoint security protects devices such as laptops, smartphones, and tablets connected to networks. Antivirus software and device monitoring tools are examples.
Internet of Things (IoT) Security
IoT security protects smart devices such as smart TVs, security cameras, and wearable gadgets from cyberattacks.
COMMON CYBER THREATS
Cyber threats are continuously evolving, becoming more sophisticated and dangerous.
Malware
Malware refers to malicious software designed to damage or exploit systems. Common forms include viruses, worms, spyware, and trojans.
Ransomware
Ransomware locks or encrypts data and demands payment for restoration. Many businesses and hospitals worldwide have suffered from ransomware attacks.
Phishing
Phishing attacks trick users into revealing sensitive information through fake emails, websites, or messages that appear legitimate.
Hacking
Hackers exploit vulnerabilities in systems to gain unauthorized access to data or networks.
Denial-of-Service (DoS) Attacks
DoS attacks overload systems with traffic, causing websites or services to crash and become unavailable.
Identity Theft
Cybercriminals steal personal information to impersonate individuals for financial fraud or illegal activities
CYBER SECURITY MEASURES AND BEST PRACTICES
Protecting against cyber threats requires a combination of technology, awareness, and responsible behavior.
Strong Passwords
