+# Security Review: Pull Request #117
+## DevSecOps Demo Page with Intentional Vulnerabilities
+
+**Reviewer:** Security Code Reviewer Agent  
+**Date:** 2026-02-06  
+**PR Title:** Add DevSecOps-2649 demo page with intentional vulnerabilities for GHAS showcase  
+**Branch:** `copilot/featuredevsecops-demo-12345`
+
+---
+
+## Executive Summary
+
+This PR introduces a demonstration page designed to showcase GitHub Advanced Security (GHAS) capabilities by intentionally including multiple security vulnerabilities. While the educational intent is clear and explicitly documented, this code presents **CRITICAL security risks** if deployed to production environments.
+
+**Overall Risk Level:** 🔴 **CRITICAL** (if deployed to production)  
+**Educational Value:** ✅ **HIGH** (for GHAS demonstration)  
+**Recommendation:** ⚠️ **APPROVE WITH STRICT CONTROLS** - Must never reach production
+
+---
+
+## Vulnerability Analysis
+
+### CRITICAL Severity Issues
+
+#### 1. Hardcoded Database Credentials (CWE-798)
+**Location:** `src/webapp01/Pages/DevSecOps-2649.cshtml.cs:24`
+
+```csharp
+private const string DB_CONNECTION = "Server=prod-db.example.com;Database=ProductionDB;User Id=dbadmin;Password=P@ssw0rd123!Secure;TrustServerCertificate=true;";
+```
+
+**Vulnerability:**
+- Production database credentials embedded in source code
+- Credentials include privileged user (`dbadmin`) with clear password
+- Connection string references production server (`prod-db.example.com`)
+- Credentials will be visible in version control history permanently
+
+**Impact:**
+- **Severity:** CRITICAL
+- **CVSS Estimate:** 9.8 (Critical)
+- **Exploitability:** High - credentials in plain text
+- **Impact:** Complete database compromise, data breach, unauthorized access
+
+**Remediation:**
+```csharp
+// Use configuration system with secrets management
+private readonly IConfiguration _configuration;
+
+public DevSecOps2649Model(ILogger<DevSecOps2649Model> logger, IConfiguration configuration)
+{
+    _logger = logger;
+    _configuration = configuration;
+}
+
+// Retrieve from Azure Key Vault, AWS Secrets Manager, or environment variables
+var connectionString = _configuration.GetConnectionString("ProductionDB");
+```
+
+**References:**
+- CWE-798: Use of Hard-coded Credentials
+- OWASP A07:2021 - Identification and Authentication Failures
+
+---
+
+#### 2. Hardcoded API Key (CWE-798)
+**Location:** `src/webapp01/Pages/DevSecOps-2649.cshtml.cs:25`
+
+```csharp
+private const string API_KEY = "demo_api_key_51ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnop1234567890_FOR_TESTING_ONLY";
+```
+
+**Vulnerability:**
+- API key stored as constant in source code
+- Despite the "FOR_TESTING_ONLY" suffix, pattern is realistic enough to be exploitable
+- Key is logged in application logs (line 61)
+
+**Impact:**
+- **Severity:** CRITICAL
+- **CVSS Estimate:** 9.1 (Critical)
+- **Exploitability:** High - key available in source
+- **Impact:** Unauthorized API access, potential data exfiltration, service abuse
+
+**Remediation:**
+```csharp
+// Store in secure configuration
+private string GetApiKey()
+{
+    return _configuration["ApiKeys:ExternalService"] 
+        ?? throw new InvalidOperationException("API key not configured");
+}
+```
+
+**References:**
+- CWE-798: Use of Hard-coded Credentials
+- OWASP A02:2021 - Cryptographic Failures
+
+---
+
+#### 3. SQL Injection Vulnerability (CWE-89)
+**Location:** `src/webapp01/Pages/DevSecOps-2649.cshtml.cs:257`
+
+```csharp
+string unsafeQuery = $"SELECT * FROM Users WHERE UserId = '{userId}'";
+```
+
+**Vulnerability:**
+- Direct string concatenation for SQL query construction
+- User input (`userId`) inserted without sanitization or parameterization
+- Classic SQL injection attack vector
+
+**Impact:**
+- **Severity:** CRITICAL
+- **CVSS Estimate:** 9.8 (Critical)
+- **Exploitability:** High - trivial to exploit with input like `' OR '1'='1`
+- **Impact:** Complete database compromise, data theft, data manipulation, privilege escalation
+
+**Attack Example:**
+```sql
+-- Input: ' OR '1'='1' --
+-- Results in: SELECT * FROM Users WHERE UserId = '' OR '1'='1' --'
+-- Returns all users in database
+```
+
+**Remediation:**
+```csharp
+// Use parameterized queries
+private async Task<List<string>> GetUserDataSafe(string userId)
+{
+    var results = new List<string>();
+    
+    using var connection = new SqlConnection(_configuration.GetConnectionString("Database"));
+    string safeQuery = "SELECT * FROM Users WHERE UserId = @UserId";
+    
+    using var command = new SqlCommand(safeQuery, connection);
+    command.Parameters.AddWithValue("@UserId", userId);
+    
+    await connection.OpenAsync();
+    using var reader = await command.ExecuteReaderAsync();
+    
+    while (await reader.ReadAsync())
+    {
+        results.Add(reader.GetString(0));
+    }
+    
+    return results;
+}
+```

+- OWASP A03:2021 - Injection
+
+---
+
+### HIGH Severity Issues
+
+#### 4. Log Injection / Log Forging (CWE-117)
+**Locations:** Multiple instances throughout the file
+
+**Primary Examples:**
+```csharp
+// Line 51: User-controlled userId in logs
+_logger.LogInformation($"Page accessed by user: {userId} from IP: {ipAddress} with User-Agent: {userAgent}");
+
+// Line 170: Username directly in logs
+_logger.LogWarning($"User login attempt: {username}");
+
+// Line 171: Unsanitized username in structured log
+_logger.LogInformation($"Processing request for user: {username} at {DateTime.UtcNow}");
+```
+
+**Vulnerability:**
+- User-supplied input directly interpolated into log messages
+- No sanitization of newline characters or control characters
+- Attackers can inject fake log entries to hide malicious activity or frame others
+
+**Impact:**
+- **Severity:** HIGH
+- **CVSS Estimate:** 7.5 (High)
+- **Exploitability:** Medium - requires log access for full impact
+- **Impact:** Log corruption, evidence tampering, SIEM evasion, compliance violations
+
+**Attack Example:**
+```plaintext
+Username: admin
+↓ Becomes ↓
+admin\nINFO: Authentication successful for user: hacker\nINFO: Database backup completed
+```
+
+**Remediation:**
+```csharp
+// Option 1: Use structured logging with properties
+_logger.LogInformation("Page accessed by user {UserId} from IP {IpAddress}", 
+    SanitizeLogInput(userId), ipAddress);
+
+// Option 2: Sanitization helper
+private string SanitizeLogInput(string input)
+{
+    if (string.IsNullOrEmpty(input)) return "empty";
+    
+    return input
+        .Replace("\r", "")
+        .Replace("\n", "")
+        .Replace("\t", " ")
+        .Trim();
+}
+
+// Option 3: Use source-generated structured logging (.NET 6+)
+[LoggerMessage(Level = LogLevel.Information, Message = "Page accessed by user {userId}")]
+partial void LogPageAccess(string userId);
+```

+
+#### 5. Regular Expression Denial of Service (ReDoS) (CWE-1333)
+**Location:** `src/webapp01/Pages/DevSecOps-2649.cshtml.cs:29`
+
+```csharp
+private static readonly Regex InsecureRegexPattern = new Regex(@"^(a+)+$", RegexOptions.Compiled);
+```
+
+**Vulnerability:**
+- Catastrophic backtracking pattern with nested quantifiers
+- Exponential time complexity O(2^n)
+- Can cause server-side denial of service with malicious input
+
+**Impact:**
+- **Severity:** HIGH
+- **CVSS Estimate:** 7.5 (High)
+- **Exploitability:** High - simple input causes exponential processing time
+- **Impact:** Application hang, CPU exhaustion, service unavailability
+
+**Attack Example:**
+```csharp
+// Input: "aaaaaaaaaaaaaaaaaa!" (18 'a's followed by '!')
+// Processing time: Several seconds to minutes
+// Input: "aaaaaaaaaaaaaaaaaaaaaaaaaaaa!" (28 'a's)
+// Processing time: Hours (effectively infinite)
+```
+
+**Remediation:**
+```csharp
+// Option 1: Use timeout
+private static readonly Regex SafeRegexPattern = new Regex(
+    @"^a+$",  // Simplified pattern without nested quantifiers
+    RegexOptions.Compiled,
+    TimeSpan.FromMilliseconds(100)
+);
+
+// Option 2: Pre-validate input length
+if (input.Length > 100)
+{
+    throw new ArgumentException("Input too long");
+}
+
+// Option 3: Use non-backtracking regex (NET 7+)
+private static readonly Regex SafeRegex = new Regex(
+    @"^a+$", 
+    RegexOptions.NonBacktracking
+);
+```
+
+**References:**
+- CWE-1333: Inefficient Regular Expression Complexity
+- OWASP: Regular Expression Denial of Service (ReDoS)
+
+---
+
+### MEDIUM Severity Issues
+
+#### 6. Insecure Deserialization Pattern (CWE-502)
+**Location:** `src/webapp01/Pages/DevSecOps-2649.cshtml.cs:117-118`
+
+```csharp
+string jsonData = JsonConvert.SerializeObject(LatestSecurityNews);
+var deserializedNews = JsonConvert.DeserializeObject<List<SecurityNewsItem>>(jsonData);
+```
+
+**Vulnerability:**
+- Using Newtonsoft.Json without type name handling restrictions
+- While current code only deserializes trusted data, the pattern is unsafe
+- Version downgrade to 12.0.2 introduces known vulnerabilities
+
+**Impact:**
+- **Severity:** MEDIUM (current context) / HIGH (if pattern is copied)
+- **CVSS Estimate:** 6.5 (Medium)
+- **Exploitability:** Medium - requires control over serialized data
+- **Impact:** Remote code execution, arbitrary object instantiation
+
+**Remediation:**
+```csharp
+// Option 1: Use System.Text.Json (already referenced)
+using System.Text.Json;
+
+string jsonData = JsonSerializer.Serialize(LatestSecurityNews);
+var deserializedNews = JsonSerializer.Deserialize<List<SecurityNewsItem>>(jsonData);
+
+// Option 2: If Newtonsoft.Json is required, use secure settings
+var safeSettings = new JsonSerializerSettings
+{
+    TypeNameHandling = TypeNameHandling.None, // Critical: prevent type injection
+    MaxDepth = 32
+};
+var deserializedNews = JsonConvert.DeserializeObject<List<SecurityNewsItem>>(
+    jsonData, 
+    safeSettings
+);
+```
+
+**References:**
+- CWE-502: Deserialization of Untrusted Data
+- OWASP A08:2021 - Software and Data Integrity Failures
+
+---
+
+#### 7. Vulnerable Dependency Version
+**Location:** `src/webapp01/webapp01.csproj:16`
+
+```xml
+<PackageReference Include="Newtonsoft.Json" Version="12.0.2" />
+```
+
+**Vulnerability:**
+- Intentional downgrade from 13.0.1 to 12.0.2
+- Newtonsoft.Json 12.0.2 has known security vulnerabilities
+- CVE-2024-21907: Improper handling of exceptional conditions during deserialization

+- **CVSS Score:** 6.5 (Medium) per CVE-2024-21907
+- **Exploitability:** Medium - requires specific deserialization scenarios
+- **Impact:** Application crash, potential DoS
+
+**Remediation:**
+```xml
+<!-- Update to latest stable version -->
+<PackageReference Include="Newtonsoft.Json" Version="13.0.3" />
+
+<!-- Or better: Remove if System.Text.Json suffices -->
+<!-- System.Text.Json is already referenced at 8.0.4 -->
+```
+
+**References:**
+- CVE-2024-21907
+- OWASP A06:2021 - Vulnerable and Outdated Components
+
+---
+
+#### 8. Information Disclosure in Error Handling
+**Locations:** Multiple catch blocks
+
+**Examples:**
+```csharp
+// Line 126: Full exception details in logs
+_logger.LogError($"Failed to process security news: {ex.ToString()}");
+
+// Line 158: Connection string exposed in error log
+_logger.LogError($"Database connection failed: {ex.Message} - Connection string: {DB_CONNECTION}");
+
+// Line 237: Full exception stack trace
+_logger.LogError($"Regex evaluation failed: {ex.ToString()}");
+```
+
+**Vulnerability:**
+- Exception details including stack traces logged
+- Sensitive information (connection strings) included in error messages
+- Could expose internal application structure to attackers
+
+**Impact:**
+- **Severity:** MEDIUM
+- **CVSS Estimate:** 5.3 (Medium)
+- **Exploitability:** Low - requires log access
+- **Impact:** Information disclosure, reconnaissance for attackers
+
+**Remediation:**
+```csharp
+// Log exceptions securely
+try
+{
+    // Operation
+}
+catch (Exception ex)
+{
+    // Log with structured data, not ToString()
+    _logger.LogError(ex, "Failed to process security news");
+    
+    // For user-facing errors, use generic messages
+    TempData["Error"] = "An error occurred processing your request";
+}
+
+// Never log connection strings or credentials
+_logger.LogError("Database connection failed");  // No connection string!
+```
+
+**References:**
+- CWE-209: Information Exposure Through an Error Message
+- OWASP A04:2021 - Insecure Design
+
+---
+
+### LOW / INFO Severity Issues
+
+#### 9. Missing Input Validation
+**Location:** Form handlers in `OnPostTestLogForging` and `OnPostTestRegexVulnerability`
+
+**Vulnerability:**
+- Minimal validation on user input
+- No length restrictions on form fields
+- No character set validation
+
+**Remediation:**
+```csharp
+public IActionResult OnPostTestLogForging([Required][MaxLength(50)] string username)
+{
+    if (!ModelState.IsValid)
+    {
+        return Page();
+    }
+    
+    // Additional validation
+    if (!Regex.IsMatch(username, @"^[a-zA-Z0-9_-]+$"))
+    {
+        ModelState.AddModelError("username", "Invalid characters");
+        return Page();
+    }
+    
+    // Process...
+}
+```

+
+## Security Best Practices Violations Summary
+
+| Category | Finding | Severity |
+|----------|---------|----------|
+| **Secrets Management** | Hardcoded database credentials | CRITICAL |
+| **Secrets Management** | Hardcoded API key | CRITICAL |
+| **Injection** | SQL injection via string concatenation | CRITICAL |
+| **Logging** | Log injection/forging vulnerabilities | HIGH |
+| **Availability** | ReDoS vulnerability | HIGH |
+| **Deserialization** | Insecure deserialization pattern | MEDIUM |
+| **Dependencies** | Vulnerable Newtonsoft.Json version | MEDIUM |
+| **Error Handling** | Information disclosure in exceptions | MEDIUM |
+| **Input Validation** | Insufficient input validation | LOW |
+
+---
+
+## Additional Security Concerns
+
+### 1. Trust Server Certificate Setting
+```csharp
+"TrustServerCertificate=true"
+```
+This disables SSL certificate validation, making the connection vulnerable to MITM attacks.
+
+### 2. Sensitive Data in Logs
+Multiple instances of logging potentially sensitive data:
+- API keys (even truncated)
+- User agents (potential fingerprinting)
+- Full exception stack traces
+
+### 3. Missing CSRF Protection
+Form handlers don't explicitly validate anti-forgery tokens (though ASP.NET Core Razor Pages include this by default).
+
+---
+
+## Recommendations
+
+### For Educational/Demo Environment (Current Use Case)
+
+✅ **APPROVE** with the following safeguards:
+
+1. **Environment Isolation**
+   - Deploy ONLY to isolated demo/sandbox environments
+   - Never deploy to production or staging with real data
+   - Use separate Azure subscription/AWS account for demos
+
+2. **Network Restrictions**
+   - Block all external network access from demo app
+   - No real database connections
+   - No real API integrations
+
+3. **Clear Labeling**
+   ```csharp
+   #if !DEMO_ENVIRONMENT
+   #error "This code contains intentional vulnerabilities and can only be compiled for DEMO_ENVIRONMENT"
+   #endif
+   ```
+
+4. **Branch Protection**
+   - Prevent merging this branch to main/production branches
+   - Require explicit approval from security team
+   - Add CODEOWNERS rule requiring security review
+
+5. **Documentation**
+   - Add README.SECURITY.md explaining vulnerabilities
+   - Include security warnings in page UI
+   - Document expected GHAS alerts
+
+### For Production Code (If Patterns Were Accidentally Copied)
+
+🔴 **BLOCK IMMEDIATELY** and remediate:
+
+1. Remove all hardcoded credentials
+2. Implement parameterized queries
+3. Add input sanitization for logging
+4. Replace vulnerable regex patterns
+5. Update dependencies to latest secure versions
+6. Implement proper error handling without information disclosure
+
+---
+
+## GHAS Detection Validation
+
+The PR description states these vulnerabilities should trigger GHAS code scanning. Expected alerts:
+
+| Vulnerability | Expected Query | Confidence |
+|---------------|----------------|------------|
+| Hardcoded credentials | `cs/hardcoded-credentials` | ✅ High |
+| SQL injection | `cs/sql-injection` | ✅ High |
+| Log injection | `cs/log-injection` | ✅ High |
+| ReDoS | `cs/redos` | ✅ High |
+| Insecure deserialization | `cs/unsafe-deserialization` | ⚠️ Medium |
+| Vulnerable dependency | Dependabot alert | ✅ High |
+
+**Recommendation:** After merge to demo branch, verify all expected GHAS alerts appear.
+
+---
+
+## Compliance Impact
+
+This code would violate multiple compliance frameworks if deployed to production:
+
+- **PCI DSS 3.2.1** - Requirement 6.5.1 (Injection flaws)
+- **OWASP ASVS 4.0** - V2.2 (Authentication), V5.3 (Input Validation)
+- **NIST 800-53** - SC-28 (Protection of Information at Rest)
+- **ISO 27001** - A.9.4.1 (Information access restriction)
+- **SOC 2** - CC6.1 (Logical and physical access controls)
+
+---
+
+## Final Assessment
+
+### Educational Value: ⭐⭐⭐⭐⭐
+This PR effectively demonstrates GHAS capabilities by including realistic, detectable vulnerabilities with clear educational intent.
+
+### Production Risk: 🔴 CRITICAL
+If this code were deployed to production, it would result in immediate, severe security breaches.
+
+### Review Decision: ✅ APPROVED FOR DEMO ENVIRONMENT ONLY
+
+**Conditions:**
+1. ✅ Code is explicitly marked as demonstration/educational
+2. ✅ Vulnerabilities are well-documented
+3. ✅ Must be deployed only to isolated sandbox environment
+4. ✅ Branch must not be merged to main production branch
+5. ✅ Network access from demo environment must be restricted
+6. ⚠️ Add conditional compilation to prevent production builds
+7. ⚠️ Add integration tests to verify GHAS alerts trigger correctly

+# Security Review Summary: PR #117
+## Quick Reference Guide
+
+---
+
+## 🎯 Purpose
+This PR introduces an **educational demonstration page** showcasing GitHub Advanced Security (GHAS) detection capabilities through intentionally vulnerable code patterns.
+
+---
+
+## ⚠️ Overall Assessment
+
+| Aspect | Rating | Notes |
+|--------|--------|-------|
+| **Production Safety** | 🔴 CRITICAL RISK | Contains exploitable vulnerabilities |
+| **Educational Value** | ⭐⭐⭐⭐⭐ Excellent | Clear demonstration of GHAS capabilities |
+| **Documentation** | ✅ Good | Vulnerabilities are clearly marked |
+| **GHAS Detection** | ✅ Confirmed | Multiple alerts triggered as expected |
+| **Recommendation** | ⚠️ CONDITIONAL APPROVE | Only for isolated demo environment |
+
+---
+
+## 📊 Vulnerability Summary
+
+### By Severity
+
+| Severity | Count | Types |
+|----------|-------|-------|
+| 🔴 **CRITICAL** | 3 | Hardcoded credentials (2), SQL Injection (1) |
+| 🟠 **HIGH** | 2 | Log Injection, ReDoS |
+| 🟡 **MEDIUM** | 3 | Insecure deserialization, Vulnerable dependency, Information disclosure |
+| 🟢 **LOW** | 1 | Insufficient input validation |
+
+### Critical Issues Requiring Immediate Attention (If Deployed)
+
+1. **Hardcoded Database Password** - Production DB credentials in source code
+2. **Hardcoded API Key** - Exposed API credentials  
+3. **SQL Injection** - Unparameterized query construction
+4. **Log Injection** - Unsanitized user input in logs
+5. **ReDoS Vulnerability** - Catastrophic backtracking regex pattern
+
+---
+
+## 🛡️ GHAS Alert Status
+
+### ✅ Confirmed Detections (19 total alerts)
+
+| Alert Type | Count | Severity | Status |
+|------------|-------|----------|--------|
+| Log entries from user input | 1 | HIGH | ✅ Detected |
+| Insecure SQL connection | 2 | MEDIUM | ✅ Detected |
+| Generic catch clauses | 4 | LOW | ✅ Detected |
+| Redundant ToString() calls | 2 | INFO | ✅ Detected |
+| Useless assignment | 1 | INFO | ✅ Detected |
+| Inefficient ContainsKey | 1 | INFO | ✅ Detected |
+| Vulnerable dependency | 1 | HIGH | ✅ Detected (Dependabot) |
+
+### ⚠️ Expected But Not Yet Visible in Reviews
+
+These should appear in the Security tab:
+- Hardcoded credentials (secret scanning)
+- SQL Injection (CodeQL)
+- ReDoS pattern (CodeQL)
+- Insecure deserialization (CodeQL)
+
+**Note:** Some alerts may only appear in the repository's Security > Code Scanning tab rather than PR comments.
+

+
+## 📋 Deployment Checklist
+
+### ✅ Required Safeguards for Demo Environment
+
+- [ ] **Environment Isolation**
+  - Deploy to dedicated sandbox/demo Azure subscription
+  - No access to production resources or data
+  - Completely isolated network segment
+
+- [ ] **Network Controls**
+  - Block all outbound internet access
+  - No real database connections allowed
+  - No external API integrations
+
+- [ ] **Access Controls**
+  - Restrict access to security team only
+  - No customer data or PII present
+  - Read-only access for demo viewers
+
+- [ ] **Code Protection**
+  - Add conditional compilation guards
+  - Prevent accidental merge to main branch
+  - Add CODEOWNERS requiring security approval
+
+- [ ] **Documentation**
+  - Add prominent security warnings in UI
+  - Document all intentional vulnerabilities
+  - Include expected GHAS alerts list
+
+### 🚫 Production Deployment Blockers
+
+**This code MUST NEVER reach production. Deployment would result in:**
+
+- ❌ Immediate credential compromise
+- ❌ Database breach
+- ❌ Data exfiltration risk
+- ❌ Service availability issues
+- ❌ Compliance violations (PCI DSS, SOC 2, ISO 27001, GDPR)
+- ❌ Potential legal liability
+

+## 🔍 Code Patterns Demonstrated
+
+This PR successfully demonstrates detection of:
+
+### Injection Vulnerabilities
+```csharp
+// Log Injection (CWE-117)
+_logger.LogInformation($"User: {userId}");  // ❌ Unsanitized input
+
+// SQL Injection (CWE-89)  
+string query = $"SELECT * FROM Users WHERE Id = '{userId}'";  // ❌ String concatenation
+```
+
+### Credential Management Issues
+```csharp
+// Hardcoded Credentials (CWE-798)
+private const string DB_CONNECTION = "...Password=P@ssw0rd123!...";  // ❌ In source code
+private const string API_KEY = "demo_api_key_51ABC...";  // ❌ Exposed
+```
+
+### Availability Attacks
+```csharp
+// ReDoS (CWE-1333)
+private static readonly Regex InsecureRegexPattern = new Regex(@"^(a+)+$");  // ❌ Catastrophic backtracking
+```
+
+### Data Handling
+```csharp
+// Insecure Deserialization (CWE-502)
+var data = JsonConvert.DeserializeObject<T>(untrustedInput);  // ❌ Without type validation
+```
+
+---
+
+## 📖 Educational Value
+
+### What This Demonstrates
+
+✅ **Code Scanning (CodeQL)**
+- Detects injection vulnerabilities
+- Identifies insecure patterns
+- Finds logic errors and unsafe practices
+
+✅ **Secret Scanning**

+- Identifies API keys and tokens
+- Historical repository scanning
+
+✅ **Dependency Management (Dependabot)**
+- Alerts on vulnerable packages (Newtonsoft.Json 12.0.2)
+- Provides remediation guidance
+- OpenSSF Scorecard integration
+
+✅ **Security Best Practices**
+- Demonstrates real-world vulnerability patterns
+- Shows proper vs. improper coding techniques
+- Provides remediation examples
