Week 10: Security in System Design
1. Security Principles and Best Practices:
- Lecture 1: Introduction to System Security
- Define the importance of security in system design.
- Explain the principle of defense in depth.
- Lecture 2: Security Best Practices
- Discuss foundational security practices such as the principle of least privilege and the need-to-know principle.
- Explore concepts like the CIA triad (Confidentiality, Integrity, Availability).
- Lab 1: Implementing Security Best Practices
- Apply security best practices in a simple application by configuring user access permissions and implementing data encryption.
2. Authentication and Authorization:
- Lecture 3: Authentication Methods
- Explain the various authentication methods, including username/password, multi-factor authentication (MFA), and OAuth.
- Discuss the pros and cons of each method.
- Lecture 4: Authorization and Access Control
- Explore role-based access control (RBAC) and attribute-based access control (ABAC) for authorization.
- Discuss the principle of least privilege in access control.
- Lab 2: Implementing Authentication and Authorization
- Secure an application by implementing user authentication and role-based authorization.
- Test access control to verify security.
3. Data Encryption and Privacy:
- Lecture 5: Data Encryption Fundamentals
- Explain the importance of data encryption in transit and at rest.
- Discuss encryption algorithms and key management.
- Lecture 6: Privacy and Compliance
- Explore data privacy regulations like GDPR and HIPAA.
- Discuss the impact of privacy laws on system design and data handling.
- Lab 3: Implementing Data Encryption
- Encrypt sensitive data in an application and ensure secure transmission over the network.
- Conduct security audits to validate encryption.
4. Common Security Vulnerabilities and Mitigation:
- Lecture 7: Common Security Vulnerabilities
- Highlight common vulnerabilities like SQL injection, cross-site scripting (XSS), and cross-site request forgery (CSRF).
- Discuss the impact of these vulnerabilities.
- Lecture 8: Security Mitigation Strategies
- Introduce strategies for mitigating security vulnerabilities, including input validation, output encoding, and security headers.
- Explore the use of security tools like OWASP ZAP.
- Lab 4: Identifying and Mitigating Vulnerabilities
- Perform security testing on a web application to identify vulnerabilities.
- Implement security fixes to mitigate identified issues.
Homework Assignment:
- Research and document a case study of a security breach in a well-known company, analyzing the vulnerabilities that led to the breach and proposing security improvements.
