Security Overview

The 8531 TeamSite implements a comprehensive security architecture to protect sensitive information and ensure secure access to team resources. This document outlines all security measures, policies, and best practices.

🛡️ Security Architecture

Zero Trust Model

The platform follows a zero-trust security model where:

All requests are untrusted by default
Authentication is required for all protected resources
Authorization is verified on every request
Principle of least privilege is enforced

Multi-Layer Security

Authentication Layer
- OAuth 2.0 via auth.8531.ca
- JWT token validation
- Role-based access control
Application Layer
- Input validation and sanitization
- SQL injection prevention
- XSS protection
Infrastructure Layer**
- HTTPS enforcement
- Security headers
- CORS policies
Data Layer
- Encrypted data transmission
- Secure API access
- Audit logging

🔐 Authentication Security

JWT Token Security

Token Structure

interface JWTPayload {
  sub: string;        // User ID (non-modifiable)
  email: string;      // Verified email
  role: string;       // Assigned role
  exp: number;        // Expiration (1 hour)
  iat: number;        // Issued at
  iss: string;        // Issuer (auth.8531.ca)
  aud: string;        // Audience (8531-apps)
}

Security Features

RS256 Algorithm: Asymmetric encryption with public/private key pair
Short Lifespan: 1-hour expiration with refresh capability
Secure Storage: HTTP-only, secure, SameSite cookies
Automatic Rotation: Public keys fetched from auth gateway

Token Validation Process

Verify token signature with public key
Check token expiration
Validate issuer and audience
Extract and verify user role
Grant appropriate access level

OAuth 2.0 Security

Provider Configuration

Google OAuth: Primary authentication provider
PKCE: Proof Key for Code Exchange (recommended for SPAs)
State Parameter: CSRF protection
Nonce: Replay attack prevention

Security Measures

HTTPS Required: All OAuth communications over TLS
Scope Limitation: Minimum required permissions only
Token Validation: Server-side verification of all tokens
Session Management: Secure cookie handling

🌐 Web Security

}

CORS Configuration

Production CORS

{
  "origin": ["https://team.8531.ca"],
  "credentials": true,
  "methods": ["GET", "POST", "PUT", "DELETE", "OPTIONS"],
  "allowedHeaders": ["Content-Type", "Authorization"]
}

Development CORS

{
  "origin": ["http://localhost:4321", "https://dev.team.8531.ca"],
  "credentials": true,
  "methods": ["GET", "POST", "PUT", "DELETE", "OPTIONS"],
  "allowedHeaders": ["Content-Type", "Authorization"]
}

🔒 Access Control

Role-Based Access Control (RBAC)

Role Hierarchy

Guest
- Public content only
- No authentication required
- Most restrictive access
Member
- Member-only content
- Basic team resources
- Cannot see draft/review content
CoreTeam
- All Member content
- Internal team resources
- Can see draft/review content
- Cannot see admin-only content
Admin
- Full access to all content
- Administrative functions
- Can access archived content
- Most permissive access

Access Enforcement

Route Middleware: Validates roles on every protected route
API Protection: All API endpoints verify user role
Content Filtering: Navigation filtered by user role
Component Guards: UI elements hidden based on permissions

Content Access Control

Frontmatter-Based Control

---
title: "Sensitive Document"
description: "Confidential information"
roles: ["CoreTeam", "Admin"]  # Access control
status: "draft"             # Lifecycle status
pagefind: false            # Exclude from search
---

Status-Based Access
