IGNOU MBA MMPC-08: Information Technology for Managers
Unit 6: Information System Economics and Security
Introduction
Information System (IS) economics and security are two crucial aspects of IT management. This unit explores the economic impact of IS, cost-benefit analysis, investment decisions, security risks, and mitigation strategies.
1. Information System Economics
1.1 Economic Impact of Information Systems
- Enhances productivity and efficiency.
- Reduces operational costs.
- Improves decision-making through data analysis.
- Enables automation and digital transformation.
1.2 Cost-Benefit Analysis of Information Systems
- Tangible Benefits: Increased revenue, cost savings, faster processing time.
- Intangible Benefits: Improved customer satisfaction, brand value, market competitiveness.
1.3 Investment Decisions in Information Systems
- Capital Investment Considerations: Hardware, software, maintenance costs.
- Return on Investment (ROI): Measuring financial returns from IT investments.
- Total Cost of Ownership (TCO): Includes direct and indirect costs.
- Risk Assessment in IT Investments: Identifying risks associated with IS deployment.
2. Information System Security
2.1 Introduction to IS Security
- Protects data, networks, and systems from cyber threats.
- Ensures confidentiality, integrity, and availability (CIA Triad).
2.2 Security Threats in Information Systems
- Malware (Viruses, Worms, Trojans, Ransomware).
- Phishing and Social Engineering Attacks.
- Denial of Service (DoS) and Distributed DoS Attacks.
- Insider Threats and Data Breaches.
2.3 Security Measures and Mitigation Strategies
- Authentication and Access Control: Multi-factor authentication (MFA), biometric security.
- Encryption and Data Protection: Securing sensitive data with cryptographic techniques.
- Firewalls and Intrusion Detection Systems (IDS).
- Regular Security Audits and Compliance Standards.
2.4 Information Security Frameworks and Policies
- ISO 27001: International standard for IS security management.
- GDPR and Data Privacy Laws.
- Cybersecurity Policies and Best Practices.
3. Role of IS Security in Business Continuity and Disaster Recovery
3.1 Business Continuity Planning (BCP)
- Ensures continued operations during disruptions.
- Risk management strategies.
3.2 Disaster Recovery Planning (DRP)
- Backup and recovery strategies.
- Disaster recovery sites (Hot, Warm, and Cold sites).
4. Practical Applications and Experiments
4.1 Experiment: Conducting a Risk Assessment for an IT System
Objective: Identify potential security risks in an organization’s IT infrastructure.
Steps:
- Assess system vulnerabilities.
- Identify potential threats.
- Propose mitigation strategies.
4.2 Experiment: Implementing an Encryption Protocol
Objective: Understand how encryption secures data.
Steps:
- Choose an encryption algorithm (AES, RSA).
- Encrypt a sample file.
- Decrypt the file and verify integrity.
5. Assignment Questions
- Explain the economic impact of information systems in modern businesses.
- What are the key components of cost-benefit analysis in IS investment?
- Define and explain the CIA triad in IS security.
- Discuss various security threats in information systems.
- Describe the role of business continuity and disaster recovery planning.
6. Self-Study Questions
- What is the significance of Total Cost of Ownership (TCO) in IT investments?
- Explain different types of malware and their impacts.
- How does encryption enhance data security?
- What are the benefits of implementing ISO 27001?
- Describe an example of a major cybersecurity breach and its consequences.
7. Exam Questions
Short Answer Questions:
- Define information system security.
- List three economic benefits of IS in organizations.
- What is phishing, and how can it be prevented?
- Explain the importance of disaster recovery planning.
- What is the role of firewalls in cybersecurity?
Long Answer Questions:
- Discuss the economic impact of IS with relevant examples.
- Explain different security threats in information systems and their countermeasures.
- How do organizations assess risks before investing in information systems?
- Describe the role of encryption and access control in IS security.
- Compare and contrast business continuity planning (BCP) and disaster recovery planning (DRP).
Conclusion
This unit provides an in-depth understanding of IS economics and security, covering financial aspects of IS investments and the importance of cybersecurity in business operations. Effective IS management ensures both economic viability and protection against cyber threats.
