Cyber security is the practice of protecting computer systems,
networks, and data from digital attacks and unauthorized access.
It involves various measures and technologies to ensure the
confidentiality, integrity, and availability of information in the
digital world. Here are detailed notes on cyber security:
1. Importance of Cyber security:
In the modern digital age, cybersecurity is crucial to safeguard
sensitive data and information from cyber threats and attacks.
Cyber security helps protect individuals, organizations, and
governments from financial losses, reputation damage, and legal
consequences resulting from cyber incidents.
2. Cyber Threat Landscape:
Understand the various types of cyber threats, including malware
(viruses, worms, and ransom ware), phishing attacks, social
engineering, denial-of-service (DoS) attacks, and insider threats.
Be aware of the evolving nature of cyber threats, with attackers
using advanced techniques and zero-day vulnerabilities to exploit
targets.
3. Principles of Cyber security:
Confidentiality: Ensuring that sensitive information is accessible
only to authorized individuals or systems.
Integrity: Protecting data from unauthorized modifications or
tampering.
Availability: Ensuring that information and resources are
accessible and usable when needed.
Authentication: Verifying the identity of users or systems to grant
access to resources.
Authorization: Assigning appropriate permissions and access
levels based on user roles and responsibilities.
4. Cyber security Measures and Best Practices:
Strong Passwords: Encourage the use of complex and unique
passwords for each account or system.
Multi-Factor Authentication (MFA): Implement MFA to add an extra
layer of security for user logins.
Firewalls: Use firewalls to control network traffic and prevent
unauthorized access.
Encryption: Utilize encryption to protect data both in transit and at
rest.
