Cyber Security cs50 | Lecture 01 | By Harvard University

Cybersecurity, often spelled as "cyber security," is the practice of protecting computer systems, networks, and data from theft, damage, or unauthorized access. It encompasses various technologies, processes, and practices designed to safeguard digital information and ensure the confidentiality, integrity, and availability of data.

Key elements of cybersecurity include:

Access Control: Managing and controlling who can access computer systems and data. This includes using strong passwords, multi-factor authentication, and user permissions.

Network Security: Protecting the integrity and privacy of data during its transmission across networks. This involves firewalls, encryption, and intrusion detection systems.

Endpoint Security: Securing individual devices such as computers, smartphones, and tablets from malware and other threats.

Application Security: Ensuring that software and applications are developed and used securely, which includes regular patching and vulnerability assessments.

Data Security: Protecting sensitive data through encryption and access controls, as well as ensuring data backup and recovery measures are in place.

Security Awareness and Training: Educating employees and users about cybersecurity best practices and potential threats to reduce human error.

Incident Response: Developing plans and processes to address and mitigate security breaches when they occur.

Security Assessment and Auditing: Regularly testing and assessing the security of systems and networks to identify vulnerabilities and weaknesses.

Compliance and Regulation: Adhering to industry-specific regulations and legal requirements related to data protection and privacy.

Cloud Security: Ensuring the security of data and applications hosted in cloud environments, such as Amazon Web Services (AWS) and Microsoft Azure.

Cybersecurity is a critical concern in today's interconnected world, as cyber threats are constantly evolving and becoming more sophisticated. Organizations and individuals need to stay vigilant, adopt best practices, and keep their security measures up to date to protect against a wide range of cyberattacks, including malware, phishing, ransomware, and more. ... https://www.youtube.com/watch?v=Itvq9BzjIr4
