Cybersecurity is the practice of protecting computers, networks, programs, and data from unauthorized access, attacks, damage, or theft. In other words, it’s about keeping digital information safe from hackers, viruses, and other online threats.
With the rise of the internet, smartphones, cloud computing, and online services, cybersecurity has become essential for individuals, businesses, and governments.
Key Goals of Cybersecurity
- Confidentiality – Ensuring that sensitive information is only accessible to authorized users.
- Integrity – Making sure data is accurate and has not been tampered with.
- Availability – Ensuring that systems and data are accessible when needed.
Examples of Cybersecurity Measures
- Using strong passwords and two-factor authentication (2FA).
- Installing antivirus and anti-malware software.
- Encrypting sensitive data to protect it from unauthorized access.
- Regularly updating software and systems to fix security vulnerabilities.
- Training employees and users to recognize phishing attacks and scams.
Why Cybersecurity is Important
Without proper cybersecurity, personal information, financial data, and even critical infrastructure (like hospitals or power grids) can be at risk. Cyberattacks can lead to financial loss, identity theft, or reputational damage.
In short, cybersecurity is the shield that protects our digital world.
