How to Prepare for the Secure Software Design OA: Topics to Focus on 👨🏻🏫
In the Secure Software Design D487 course, there are several key concepts that you’ll need to understand deeply to perform well in your assessments. Below, I’ve broken down four of these concepts, using comparisons, tables, and real-world examples to make them easier to grasp.
- SAMM vs. BSIMM Models
SAMM (Software Assurance Maturity Model) and BSIMM (Building Security In Maturity Model) are two models that are employed in assessing security programs as well as improving the security of organizations that involve themselves in software development. Here’s how they compare:
| Feature | SAMM (Software Assurance Maturity Model) | BSIMM (Building Security In Maturity Model) |
|---|---|---|
|
Purpose
|
To provide a roadmap for improving software security practices through self-assessment.
|
To measure and compare an organization’s software security practices against industry norms.
|
|
Focus
|
Customizable and adaptable to the specific needs of an organization.
|
Emphasizes benchmarking against industry peers and collecting data from real-world security initiatives. |
|
Approach
|
Proactive – encourages continuous improvement and integration of security practices.
|
Reactive – analyzes existing practices and suggests improvements based on industry data.
|
|
Assessment
|
Involves both qualitative and quantitative analysis, with a focus on defining a maturity level.
|
Primarily qualitative, based on observations and interviews, to identify common practices.
|
|
Applicability
|
Suitable for organizations of all sizes looking to create or enhance their software security programs.
|
Best suited for large organizations that want to benchmark their security practices against others. |
Real-World Example: A small tech startup may choose to implement SAMM because it offers a flexible approach that can be tailored to their growth and development stages. Conversely, a very big organization may need to use it to benchmark its security practices with the rest of the organization in its financial industry.
- Fundamental Goals of the Security Development Lifecycle (SDL)
Security Development Lifecycle (SDL) is a process of creating more secure software and this process has come up with security checks that can be implemented in every phase of software development. The fundamental goals of SDL are:
- Reduction of Security Risks: SDL, therefore, proposes making security practices take a central place right from the development phase in a bid to reduce the possibility of the creation of vulnerable products in the final product development phase.
- Compliance with Standards: This aspect is critical as SDL helps in developing the software with security standards of the industries and legal frameworks, thus minimal chances of legal problems or security break-ins.
- Continuous Improvement: SDL is not a one-time point; it involves continuous evaluation and improvement of security measures in response to threat changes and technology advancement.
Table: Stages and Goals of SDL
| Stage | Key Goal | Activities Involved |
|---|---|---|
|
Requirements
|
Identify security objectives
|
Define security requirements, conduct risk assessments.
|
|
Design
|
Incorporate security into the architecture
|
Threat modeling, security design reviews.
|
|
Implementation
|
Write secure code
|
Code reviews, static analysis.
|
|
Verification
|
Validate security
|
Penetration testing, dynamic analysis.
|
|
Release
|
Secure deployment
|
Security sign-off, post-release monitoring.
|
|
Response
|
Address security incidents
|
Incident response planning, patch management. |
Real-World Example: An e-commerce company might adopt SDL to ensure that customer data is securely handled, from the design phase (where encryption methods are planned) to the release phase (where the software is tested for vulnerabilities before deployment).
- Agile vs. Waterfall Project Management
Agile and Waterfall are two distinct project management methodologies, each with its own advantages and disadvantages, particularly in the context of software development.
| Aspect | Agile | Waterfall |
|---|---|---|
|
Approach
|
Iterative and incremental
|
Linear and sequential
|
|
Flexibility
|
Highly flexible – changes can be made throughout the project.
|
Less flexible – changes are costly and difficult to implement after the project starts.
|
|
Client Involvement
|
High – clients can provide feedback after each iteration.
|
Low – clients typically review the product only after completion.
|
|
Project Phases
|
Overlapping – design, development, and testing happen simultaneously.
|
Distinct – each phase (requirements, design, implementation, testing, deployment) is completed before the next one begins.
|
|
Time to Market
|
Faster – early delivery of functional components.
|
Slower – full product delivered at the end of the project. |
Real-World Example: A tech company developing a mobile app might choose Agile to quickly release and iterate on new features based on user feedback. Conversely, a government contractor building a mission-critical system might opt for Waterfall to ensure that all specifications are meticulously followed.
- Threat Modeling Frameworks: STRIDE, DREAD, and PASTA
Threat modeling is a vital part of secure software design, helping developers identify and mitigate potential security threats. STRIDE, DREAD, and PASTA are three popular frameworks used in threat modeling.
| Framework | Focus | Key Components |
|---|---|---|
|
STRIDE
|
Identifying threat types
|
Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, Elevation of Privilege.
|
|
DREAD
|
Assessing threat impact
|
Damage Potential, Reproducibility, Exploitability, Affected Users, Discoverability.
|
|
PASTA
|
Risk-based threat modeling
|
Process for Attack Simulation and Threat Analysis – focuses on identifying risks from a business perspective.
|
Real-World Example: Perhaps a banking application development team will utilize STRIDE to determine individual threats such as data: disclosure – leakage of personal and financial information; and DoS. The threats could then be evaluated based on their impact through the use of DREAD after which the identified threats could be ranked based on their potential level of threat as follows: Last, PASTA could be used to map the recognized risks to the strategic objectives of a bank, so that the threats of maximum significance are tackled initially.
