Unit 912: Foundations of Information Security

1. Introduction to Information Security

• Definition and scope of information security
• The CIA Triad:
  • Confidentiality: protecting data from unauthorized disclosure
  • Integrity: ensuring accuracy and completeness of data
  • Availability: ensuring timely and reliable access to information
• Common threats and vulnerabilities:
  • Malware, phishing, insider threats, social engineering
• Importance of protecting sensitive information

2. Risk Management Framework

• Overview of risk management in information security
• Risk identification:
  • Asset identification
  • Threat and vulnerability analysis
• Risk assessment methodologies:
  • Qualitative vs quantitative assessments
  • Risk matrices and scoring
• Risk mitigation strategies:
  • Avoidance, reduction, sharing, acceptance
• Creating and maintaining a risk management plan

3. Security Policies and Procedures

• Definition and purpose of security policies
• Types of security documentation:
  • Policies, standards, guidelines, procedures
• Steps in policy development and implementation
• Ensuring compliance and enforcement
• Examples of common security policies (e.g., acceptable use, password policy)

4. Access Control and Authentication

• Access control concepts:
  • Identification, authentication, authorization, and accountability
• Access control models:
  • Discretionary Access Control (DAC)
  • Mandatory Access Control (MAC)
  • Role-Based Access Control (RBAC)
• Authentication methods:
  • Passwords, biometrics, multi-factor authentication
• Authorization techniques and access provisioning

5. Cryptography and Encryption

• Principles of cryptography:
  • Confidentiality, integrity, non-repudiation
• Types of encryption algorithms:
  • Symmetric encryption (e.g., AES, DES)
  • Asymmetric encryption (e.g., RSA, ECC)
• Hashing functions and digital signatures
• Applications of cryptography in data transmission and storage

6. Network Security

• Fundamentals of network security
• Firewalls:
  • Types and configurations
• Intrusion Detection and Prevention Systems (IDS/IPS)
• Virtual Private Networks (VPNs) and secure tunneling
• Secure network protocols (e.g., SSL/TLS, SSH)
• Network segmentation and monitoring

7. Incident Response and Disaster Recovery

• Importance of incident response planning
• Phases of incident response:
  • Preparation, detection and analysis, containment, eradication, recovery, lessons learned
• Disaster recovery planning:
  • Business continuity considerations
  • Backup strategies
• Minimizing downtime and data loss

8. Compliance and Legal Issues

• Overview of regulatory compliance in information security
• Key regulations and standards:
  • GDPR, HIPAA, PCI DSS
• Legal implications of data breaches
• Role of information security in meeting compliance requirements

9. Security Awareness Training

• Importance of security awareness for employees
• Common security risks and how to recognize them
• Best practices for promoting a cybersecurity culture
• Designing effective training programs
