What Is Cyber Security and Why Does It Matter? |
There are various types of cyber security, including:
·
Network Security: Protects internal
networks from intrusions using tools like firewalls and antivirus software.
·
Information Security:
Focuses on protecting the integrity and privacy of data, whether in storage or
transit.
·
Application Security:
Involves building secure software that is free from vulnerabilities.
·
Cloud Security: Ensures that data
stored in cloud services is protected from leaks and breaches.
·
Operational Security: Covers
policies and procedures for managing and protecting data assets.
Why Cyber Security
Matters
As our reliance on digital platforms grows, so does the number of cyber
threats. Hackers,
cybercriminals, and even nation-state actors are constantly evolving their
tactics to exploit vulnerabilities. Here are some key reasons why cyber
security is essential:
1. Protecting
Sensitive Data
Organizations and individuals store a large amount of sensitive information
online—financial records, personal identification, health records, intellectual
property, and more. A breach in cyber security can lead to identity theft,
financial loss, and reputational damage.
2. Preventing
Financial Loss
Cyber-attacks can be incredibly costly. Ransomware attacks, in
particular, can lock organizations out of their systems unless a ransom is
paid. Cyber security measures can help prevent such financial catastrophes.
3. Ensuring
Business Continuity
Cyber
threats can disrupt business operations, resulting in downtime, data loss, and
broken customer trust. By implementing strong cyber security protocols,
companies can maintain productivity and ensure uninterrupted service.
4. Complying with
Regulations
Many industries are governed by strict regulations that mandate data
protection, such as GDPR in Europe or HIPAA in the healthcare sector. Cyber
security compliance helps organizations avoid legal penalties and maintain
customer trust.
5. Protecting
National Security
Cyber attacks on critical infrastructure such as energy grids, water
supplies, and communication systems can have devastating effects. Governments
around the world prioritize cyber security to protect national interests and
ensure public safety.

·
Man-in-the-Middle (MitM) Attacks:
Intercept communications between two parties to steal data Cyber-attacks.
