cybersecurity
Cybersecurity is the practice of protecting systems, networks, and programs from digital attacks. These attacks are often aimed at accessing, altering, or destroying sensitive information, extorting money from users, or disrupting normal business processes. Here are some key components of cybersecurity:
Types of Cyber Threats
- Malware: Malicious software, including viruses, worms, and ransomware, designed to damage or disrupt systems.
- Phishing: Deceptive attempts to acquire sensitive information by masquerading as a trustworthy entity in electronic communications.
- Denial-of-Service (DoS) Attacks: Overwhelming a system with traffic to render it unusable.
Key Concepts
- Confidentiality: Ensuring that sensitive information is accessed only by authorized individuals.
- Integrity: Maintaining the accuracy and trustworthiness of data.
- Availability: Ensuring that information and resources are accessible to authorized users when needed.
Security Measures
- Firewalls: Network security devices that monitor and control incoming and outgoing traffic based on predetermined security rules.
- Encryption: Converting data into a coded format that can only be read by those with the decryption key, protecting data in transit and at rest.
- Antivirus Software: Programs designed to detect and remove malware from systems.
- Multi-Factor Authentication (MFA): Adding additional verification steps to the login process to enhance security.
