Cybersecurity in ICT

Cybersecurity in ICT

Definition and Importance

• Cybersecurity refers to the practices, technologies, and processes designed to protect digital information, computer systems, and networks from unauthorized access, use, disclosure, disruption, modification, or destruction.
• Cybersecurity is crucial in today's digital age, as the increasing reliance on ICT systems and networks makes them vulnerable to various types of cyber threats.

Types of Cyber Threats

• Malware: malicious software, including viruses, worms, Trojan horses, and spyware, designed to harm or exploit computer systems.
• Phishing: fraudulent attempts to obtain sensitive information, such as passwords or credit card numbers, by disguising as trustworthy entities.
• Ransomware: malware that encrypts files and demands payment in exchange for the decryption key.
• Denial of Service (DoS) and Distributed Denial of Service (DDoS) Attacks: overwhelming a system or network with traffic to make it unavailable.
• Social Engineering: manipulating individuals into divulging sensitive information or performing certain actions.

Cybersecurity Measures

• Firewalls: network security systems that monitor and control incoming and outgoing network traffic.
• Encryption: converting data into a code to prevent unauthorized access.
• Antivirus Software: programs designed to detect, prevent, and remove malware.
• Strong Authentication: using unique, complex passwords and multi-factor authentication to verify user identities.
• Regular Software Updates: keeping software and systems up-to-date with the latest security patches.
• Network Segmentation: dividing a network into smaller, isolated segments to limit the spread of a breach.

Cybersecurity Best Practices

• Use strong, unique passwords and avoid using the same password across multiple accounts.
• Be cautious with email attachments and links from unknown sources.
• Keep software and systems up-to-date.
• Use two-factor authentication whenever possible.
• Back up data regularly to prevent data loss in case of a breach.
• Implement a incident response plan to respond quickly and effectively in case of a security breach.

Cybersecurity Frameworks and Standards

• NIST Cybersecurity Framework: a voluntary framework for managing and reducing cybersecurity risk.
• ISO 27001: an international standard for implementing an Information Security Management System (ISMS).
• PCI-DSS: a standard for securing payment card data.

Cybersecurity Careers

• Security Analyst: responsible for monitoring and analyzing network traffic to detect and respond to security threats.
• Penetration Tester: simulates cyber attacks to test an organization's defenses.
• Chief Information Security Officer (CISO): oversees and implements an organization's cybersecurity strategy.
• Incident Response Specialist: responds to and manages security incidents.
