Business Case
Executive Summary
Objective: To enhance the security of our systems by implementing Two-Factor Authentication (2FA).
Expected Outcome: Improve the security posture, reduce the risk of unauthorized access, and protect sensitive information.
Problem Statement
Current Challenges:
- Increasing incidents of unauthorized access.
- Weak password policies leading to vulnerabilities.
- Growing concerns over data breaches and compliance requirements.
Need for 2FA Implementation:
- Strengthen security measures.
- Ensure compliance with regulatory requirements.
- Protect sensitive data from unauthorized access.
Solution Overview
What is 2FA:
Two-Factor Authentication (2FA) adds an additional layer of security by requiring not only a password and username but also something that only the user has on them, i.e., a piece of information only they should know or have immediately to hand – such as a physical token, a smartphone app, or a biometric.
Types of 2FA:
- SMS-based Verification: Sends a one-time code to the user's mobile phone.
- Authenticator Apps: Apps like Google Authenticator or Authy generate time-based codes.
- Hardware Tokens: Physical devices that generate a code or require insertion into a computer.
- Biometric Verification: Uses fingerprints or facial recognition to verify identity.
Benefits of 2FA
- Enhanced Security: Significantly reduces the risk of unauthorized access.
- Compliance: Meets regulatory requirements for data protection.
- User Trust: Increases user confidence in the security of our systems.
- Mitigation of Phishing: Reduces the effectiveness of phishing attacks.
- Cost Savings: Potentially lower costs associated with data breaches and cyber incidents.
Implementation Plan
Phase 1:
- Conduct a risk assessment and identify systems requiring 2FA.
- Select the appropriate 2FA methods (e.g., SMS, authenticator apps).
Phase 2:
- Develop and test the 2FA integration.
- Create user documentation and training materials.
Phase 3:
- Roll out 2FA to a pilot group and gather feedback.
- Make necessary adjustments based on feedback.
Phase 4:
- Full deployment of 2FA across all identified systems.
- Monitor and support post-implementation.
Cost Analysis
Initial Costs:
- Cost of 2FA software and hardware tokens.
- Implementation and integration costs.
- Training and documentation costs.
Operational Costs:
- Maintenance and support for 2FA systems.
- Ongoing training and updates.
ROI Estimation:
- Reduction in costs related to data breaches.
- Improved compliance reducing potential fines.
- Increased productivity and user confidence.
Risk Assessment
Technical Risks:
- Integration challenges with existing systems.
- User resistance or difficulties in adoption.
- Potential downtime during implementation.
Mitigation Strategies:
- Thorough testing and pilot program to identify issues early.
- Comprehensive user training and support.
- Backup and recovery plans to minimize downtime.
Alternatives Considered
- Single Sign-On (SSO): Simplifies user access but does not provide the same level of security as 2FA.
- Password Policies: Strengthening passwords can help but does not address the vulnerabilities addressed by 2FA.
- Biometric Only: More secure but can be cost-prohibitive and less user-friendly.
Conclusion and Recommendations
Recommendation: Implement 2FA using a combination of authenticator apps and SMS-based verification to enhance security while ensuring user convenience.
Next Steps:
- Finalize the selection of 2FA methods.
- Begin Phase 1 risk assessment and system identification.
- Develop and test the 2FA integration.
- Prepare user documentation and training materials.
