+## 11. Anemic Domain Model Detection
+
+### Martin Fowler's Original Blog Post (2003)
+
+**Blog Post: "Anemic Domain Model"** (November 25, 2003)
+- Author: Martin Fowler
+- Published: November 25, 2003
+- Described as an anti-pattern related to domain driven design and application architecture
+- Basic symptom: domain objects have hardly any behavior, making them little more than bags of getters and setters
+- Reference: [Martin Fowler - Anemic Domain Model](https://martinfowler.com/bliki/AnemicDomainModel.html)
+
+**Key Problems Identified:**
+- "The basic symptom of an Anemic Domain Model is that at first blush it looks like the real thing"
+- "There are objects, many named after the nouns in the domain space, and these objects are connected with the rich relationships and structure that true domain models have"
+- "The catch comes when you look at the behavior, and you realize that there is hardly any behavior on these objects"
+- "This is contrary to the basic idea of object-oriented design; which is to combine data and process together"
+
+**Why It's an Anti-pattern:**
+- Fowler argues that anemic domain models incur all of the costs of a domain model, without yielding any of the benefits
+- The logic that should be in a domain object is domain logic - validations, calculations, business rules
+- Separating data from behavior violates core OOP principles
+- Reference: [Wikipedia - Anemic Domain Model](https://en.wikipedia.org/wiki/Anemic_domain_model)
+
+### Rich Domain Model vs Transaction Script
+
+**Martin Fowler: Transaction Script Pattern**
+- Transaction Script organizes business logic by procedures where each procedure handles a single request
+- Good for simple logic with not-null checks and basic calculations
+- Reference: [Martin Fowler - Transaction Script](https://martinfowler.com/eaaCatalog/transactionScript.html)
+
+**When to Use Rich Domain Model:**
+- If you have complicated and everchanging business rules involving validation, calculations, and derivations
+- Object model handles complex domain logic better than procedural scripts
+- Reference: [InformIT - Domain Logic Patterns](https://www.informit.com/articles/article.aspx?p=1398617&seqNum=2)
+
+**Comparison:**
+- Transaction Script is better for simple logic
+- Domain Model is better when things get complicated with complex business rules
+- You can refactor from Transaction Script to Domain Model, but it's a harder change
+- Reference: [Medium - Transaction Script vs Domain Model](https://medium.com/@vibstudio_7040/transaction-script-active-record-and-domain-model-the-good-the-bad-and-the-ugly-c5b80a733305)
+
+### Domain-Driven Design Context
+
+**Eric Evans: Domain-Driven Design** (2003)
+- Entities should have both identity and behavior
+- Rich domain models place business logic within domain entities
+- Anemic models violate DDD principles by separating data from behavior
+- Reference: Already covered in Section 10 - [Domain-Driven Design Book](#domain-driven-design)
+
+**Community Discussion:**
+- Some argue anemic models can follow SOLID design principles
+- However, consensus among DDD practitioners aligns with Fowler's anti-pattern view
+- Reference: [Stack Overflow - Anemic Domain Model Anti-Pattern](https://stackoverflow.com/questions/6293981/concrete-examples-on-why-the-anemic-domain-model-is-considered-an-anti-pattern)

+
+## 12. Aggregate Boundary Validation (DDD Tactical Patterns)
+
+### Eric Evans: Domain-Driven Design (2003)
+
+**Original Book Definition:**
+- Aggregate: "A cluster of associated objects that we treat as a unit for the purpose of data changes"
+- An aggregate defines a consistency boundary around one or more entities
+- Exactly one entity in an aggregate is the root
+- Reference: [Microsoft Learn - Tactical DDD](https://learn.microsoft.com/en-us/azure/architecture/microservices/model/tactical-ddd)
+
+**DDD Reference Document** (2015)
+- Official Domain-Driven Design Reference by Eric Evans
+- Contains comprehensive definitions of Aggregates and boundaries
+- Reference: [Domain Language - DDD Reference PDF](https://www.domainlanguage.com/wp-content/uploads/2016/05/DDD_Reference_2015-03.pdf)

+### Vaughn Vernon: Implementing Domain-Driven Design (2013)
+
+**Chapter 10: Aggregates** (Page 347)

+- Practical examples of aggregate boundary enforcement
+- Reference: [SOCADK - Tactical DDD](https://socadk.github.io/design-practice-repository/activities/DPR-TacticDDD.html)
+
+### Why Aggregate Boundaries Matter
+
+**Transactional Boundary:**
+- What makes it an aggregate is the transactional boundary
+- Changes to aggregate must be atomic
+- Ensures consistency within the boundary
+- Reference: [Medium - Mastering Aggregate Design](https://medium.com/ssense-tech/ddd-beyond-the-basics-mastering-aggregate-design-26591e218c8c)
+
+**Cross-Aggregate References:**
+- Aggregates should only reference other aggregates by ID, not direct entity references
+- Prevents tight coupling between aggregates
+- Maintains clear boundaries

+- "It is never a good idea to hardcode a password"
+- Makes fixing the problem extremely difficult
+- Reference: [OWASP - Hardcoded Password Vulnerability](https://owasp.org/www-community/vulnerabilities/Use_of_hard-coded_password)
+
+### Key Security Principles
+
+**Don't Hardcode Secrets:**
+- Secrets should not be hardcoded
+- Should not be unencrypted
+- Should not be stored in source code
+- Reference: [OWASP Secrets Management Cheat Sheet](https://cheatsheetseries.owasp.org/cheatsheets/Secrets_Management_Cheat_Sheet.html)
+
+**Centralized Management:**
+- Growing need to centralize storage, provisioning, auditing, rotation, and management of secrets
+- Control access and prevent secrets from leaking
+- Use purpose-built tools for encryption-at-rest
+- Reference: [OWASP SAMM - Secret Management](https://owaspsamm.org/model/implementation/secure-deployment/stream-b/)
+
+**Prevention Tools:**
+- Use pre-commit hooks to prevent secrets from entering codebase
+- Automated scanning in CI/CD pipelines
+- Reference: [GitHub OWASP Secrets Management](https://github.com/dominikdesmit/owasp-secrets-management)
+
+### GitHub Secret Scanning
+
+**Official GitHub Documentation:**
+- About Secret Scanning: Automated detection of secrets in repositories
+- Scans for patterns and heuristics matching known types of secrets
+- Reference: [GitHub Docs - Secret Scanning](https://docs.github.com/code-security/secret-scanning/about-secret-scanning)
+
+**How It Works:**
+- Automatically scans repository contents for sensitive data (API keys, passwords, tokens)
+- Scans commits, issues, and pull requests continuously
+- Real-time alerts to repository administrators
+- Reference: [GitHub Docs - Keeping Secrets Secure](https://docs.github.com/en/code-security/secret-scanning)
+
+**AI-Powered Detection:**
+- Copilot Secret Scanning uses large language models (LLMs)
+- Identifies unstructured secrets (generic passwords) in source code
+- Enhances detection beyond pattern matching
+- Reference: [GitHub Docs - Copilot Secret Scanning](https://docs.github.com/en/code-security/secret-scanning/copilot-secret-scanning)
+
+**Supported Patterns:**
+- 350+ secret patterns detected
+- AWS, GitHub, NPM, SSH, GCP, Slack, Basic Auth, JWT tokens
+- Reference: [GitHub Docs - Supported Patterns](https://docs.github.com/en/code-security/secret-scanning/introduction/supported-secret-scanning-patterns)
+
+### Mobile Security
+
+**OWASP Mobile Security:**
+- "Secrets security is the most important issue for mobile applications"
+- Only safe way: keep secrets off the client side entirely
+- Move sensitive information to backend
+- Reference: [GitGuardian - OWASP Top 10 Mobile](https://blog.gitguardian.com/owasp-top-10-for-mobile-secrets/)

+## Anemic Domain Model Detection
+
+### Why it matters
+
+Anemic domain models violate core OOP principles:
+- ❌ **No behavior** - Entities become data bags with only getters/setters
+- ❌ **Logic in services** - Business logic scattered across service layers
+- ❌ **Violates OOP** - Separates data from behavior
+- ❌ **Higher complexity** - Loses benefits of domain modeling
+
+### Who says so?
+
+**Martin Fowler's Original Anti-Pattern:**
+- **Blog Post: "Anemic Domain Model"** (November 25, 2003)
+  > "The basic symptom of an Anemic Domain Model is that at first blush it looks like the real thing. There are objects, many named after the nouns in the domain space... The catch comes when you look at the behavior, and you realize that there is hardly any behavior on these objects."
+  - Published over 20 years ago, still relevant today
+  - [Read Fowler's post](https://martinfowler.com/bliki/AnemicDomainModel.html)
+
+**Why It's an Anti-pattern:**
+> "This is contrary to the basic idea of object-oriented design; which is to combine data and process together."
+- Incurs all costs of domain model without any benefits
+- Logic should be in domain objects: validations, calculations, business rules
+- [Wikipedia - Anemic Domain Model](https://en.wikipedia.org/wiki/Anemic_domain_model)
+
+**Rich Domain Model vs Transaction Script:**
+- **Transaction Script**: Good for simple logic (Fowler, 2002)
+- **Rich Domain Model**: Better for complex, ever-changing business rules
+- Can refactor from Transaction Script to Domain Model, but it's harder than starting right
+- [Martin Fowler - Transaction Script](https://martinfowler.com/eaaCatalog/transactionScript.html)
+
+**Domain-Driven Design Context:**
+- **Eric Evans (2003)**: Entities should have both identity AND behavior
+- Anemic models violate DDD by separating data from behavior

+
+## Aggregate Boundary Validation
+
+### Why it matters
+
+Proper aggregate boundaries ensure:
+- ✅ **Consistency** - Atomic changes within boundaries
+- ✅ **Low coupling** - Aggregates are loosely connected
+- ✅ **Clear transactions** - One aggregate = one transaction
+- ✅ **Maintainability** - Boundaries prevent complexity spread
+
+### The Rules
+
+**Vaughn Vernon's Four Rules (2013):**
+1. **Model True Invariants in Consistency Boundaries**
+2. **Design Small Aggregates**
+3. **Reference Other Aggregates by Identity**
+4. **Use Eventual Consistency Outside the Boundary**
+
+### Who says so?
+
+**Eric Evans: Domain-Driven Design (2003)**
+- **Original Definition**:
+  > "A cluster of associated objects that we treat as a unit for the purpose of data changes"
+- An aggregate defines a consistency boundary
+- Exactly one entity is the aggregate root
+- [Microsoft Learn - Tactical DDD](https://learn.microsoft.com/en-us/azure/architecture/microservices/model/tactical-ddd)
+
+**Vaughn Vernon: Implementing Domain-Driven Design (2013)**
+- **Chapter 10: Aggregates** (Page 347)
+- ISBN: 978-0321834577
+- Comprehensive rules for aggregate design
+- Three-part essay series: "Effective Aggregate Design"
+- [Available at Kalele](https://kalele.io/effective-aggregate-design/)
+
+**Why Boundaries Matter:**
+- **Transactional Boundary**: Changes must be atomic
+- **Reference by ID**: No direct entity references across aggregates
+- **Prevents tight coupling**: Maintains clear boundaries
+- [Medium - Mastering Aggregate Design](https://medium.com/ssense-tech/ddd-beyond-the-basics-mastering-aggregate-design-26591e218c8c)

+
+## Secret Detection
+
+### Why it matters
+
+Hardcoded secrets create critical security risks:
+- 🔴 **Data breaches** - Exposed credentials lead to unauthorized access
+- 🔴 **Production incidents** - Leaked tokens cause service disruptions
+- 🔴 **Compliance violations** - GDPR, PCI-DSS, SOC 2 requirements
+- 🔴 **Impossible to rotate** - Secrets in code are difficult to change
+
+### Who says so?
+
+**OWASP Security Standards:**
+- **OWASP Secrets Management Cheat Sheet**
+  > "Secrets should not be hardcoded, should not be unencrypted, and should not be stored in source code."
+  - Official best practices from OWASP Foundation
+  - [Read the cheat sheet](https://cheatsheetseries.owasp.org/cheatsheets/Secrets_Management_Cheat_Sheet.html)
+
+- **OWASP Hardcoded Password Vulnerability**
+  > "It is never a good idea to hardcode a password, as it allows all of the project's developers to view the password and makes fixing the problem extremely difficult."
+  - [OWASP Documentation](https://owasp.org/www-community/vulnerabilities/Use_of_hard-coded_password)
+
+**GitHub Secret Scanning:**
+- **Official GitHub Documentation**
+  - Automatically scans 350+ secret patterns
+  - Detects AWS, GitHub, NPM, SSH, GCP, Slack tokens
+  - AI-powered detection with Copilot Secret Scanning
+  - [GitHub Docs](https://docs.github.com/code-security/secret-scanning/about-secret-scanning)
+
+**Key Security Principles:**
+- **Centralized Management**: Use purpose-built secret management tools
+- **Prevention Tools**: Pre-commit hooks to prevent secrets entering codebase
+- **Encryption at Rest**: Never store secrets in plaintext
+- [OWASP SAMM - Secret Management](https://owaspsamm.org/model/implementation/secure-deployment/stream-b/)
+
+**Mobile Security:**
+- OWASP: "Secrets security is the most important issue for mobile applications"
+- Only safe way: keep secrets off the client side entirely
+- [GitGuardian - OWASP Top 10 Mobile](https://blog.gitguardian.com/owasp-top-10-for-mobile-secrets/)

+## Severity-Based Prioritization
+
+### Why it matters
+
+Severity classification enables:
+- ✅ **Focus on critical issues** - Fix what matters most first
+- ✅ **Reduced technical debt** - Prioritize based on impact
+- ✅ **Better CI/CD integration** - Fail builds on critical issues only
+- ✅ **Team efficiency** - Don't waste time on low-impact issues
+
+### Who says so?
