Introduction
Proper access control and data governance are essential for protecting sensitive business information and maintaining accountability. This guide explains how to implement role-based permissions, audit logging, and operational controls in your CRM/ERP system.
Role-Based Access Control (RBAC)
What is RBAC?
Role-Based Access Control assigns permissions based on job roles rather than individual users. This simplifies permission management and ensures consistent access across the organization.
Common Business Roles
- Administrator: Full system access, user management, configuration
- Sales Manager: View all sales data, manage team, run reports
- Sales Rep: Manage own leads/deals, limited reporting
- Finance: Access invoices, payments, financial reports
- Operations: Manage inventory, orders, fulfillment
- Support: View customer records, create tickets, limited editing
- Read-Only: View data only, no editing or deletion
Permission Types
Define granular permissions for each role:
- Create: Add new records
- Read: View existing records
- Update: Edit existing records
- Delete: Remove records
- Export: Download data
- Import: Bulk upload data
- Share: Grant access to others
Implementing Access Controls
1. Define Roles and Responsibilities
- Map job functions to system roles
- Identify data access requirements
- Document role definitions
- Get stakeholder approval
2. Configure Permissions
- Set object-level permissions (contacts, deals, products)
- Configure field-level security (hide sensitive fields)
- Implement record-level access (own vs. team vs. all)
- Define sharing rules and exceptions
3. Assign Users to Roles
- Create user accounts
- Assign appropriate roles
- Set up reporting hierarchies
- Configure delegation rules
4. Test and Validate
- Test each role with sample users
- Verify appropriate access levels
- Check for unintended access
- Adjust permissions as needed
Data Governance Principles
Principle of Least Privilege
Users should have only the minimum access required to perform their job. This reduces risk of accidental or malicious data exposure.
Separation of Duties
Critical functions should require multiple people. For example:
- Different people create and approve purchase orders
- Separate roles for entering and approving invoices
- Different users for inventory counts and adjustments
Data Classification
Classify data by sensitivity level:
- Public: Can be freely shared
- Internal: For company use only
- Confidential: Restricted to specific roles
- Highly Confidential: Extremely limited access
Audit Logging and Monitoring
What to Log
Maintain comprehensive audit trails:
- User actions: Login, logout, failed attempts
- Data changes: Create, update, delete operations
- Permission changes: Role assignments, access grants
- Exports: Data downloads and reports
- Configuration: System settings changes
- API access: Integration activity
Audit Log Details
Each log entry should include:
- Who performed the action (user ID)
- What action was performed
- When it occurred (timestamp)
- Where it occurred (IP address, location)
- What data was affected (record ID, field names)
- Before and after values (for updates)
Log Retention
- Retain logs for minimum 1 year (longer for compliance)
- Archive old logs to reduce storage costs
- Ensure logs are tamper-proof
- Regular backup of audit logs
Monitoring and Alerts
Security Monitoring
Monitor for suspicious activity:
- Multiple failed login attempts
- Access from unusual locations
- Large data exports
- Bulk record deletions
- Permission changes
- After-hours access
Automated Alerts
Set up notifications for:
- Failed login attempts (5+ in 10 minutes)
- Privilege escalation
- Mass data deletion
- Sensitive data access
- Configuration changes
Regular Reviews
- Weekly review of security alerts
- Monthly access rights audit
- Quarterly permission review
- Annual security assessment
User Authentication
Password Policies
- Minimum 12 characters
- Mix of uppercase, lowercase, numbers, symbols
- No common passwords or dictionary words
- Password expiry (90 days recommended)
- Prevent password reuse (last 5 passwords)
Multi-Factor Authentication (MFA)
Require MFA for:
- All administrator accounts
- Remote access
- Sensitive data access
- Financial operations
MFA methods: SMS codes, authenticator apps, hardware tokens
Session Management
- Auto-logout after inactivity (15-30 minutes)
- Limit concurrent sessions
- Require re-authentication for sensitive operations
- Secure session tokens
Data Protection Measures
Encryption
- In transit: TLS 1.3 for all connections
- At rest: AES-256 encryption for stored data
- Backups: Encrypted backup files
- Sensitive fields: Additional encryption for PII
Data Masking
Hide sensitive data from unauthorized users:
- Credit card numbers (show last 4 digits only)
- Social security numbers
- Bank account details
- Salary information
Data Retention and Deletion
- Define retention periods for different data types
- Automatic archival of old records
- Secure deletion procedures
- Comply with GDPR "right to be forgotten"
Compliance and Regulations
UK GDPR Requirements
- Lawful basis for data processing
- Data subject rights (access, rectification, erasure)
- Data breach notification (72 hours)
- Privacy by design and default
- Data protection impact assessments
Industry-Specific Compliance
- PCI DSS: Payment card data security
- SOC 2: Service organization controls
- ISO 27001: Information security management
- HIPAA: Healthcare data (if applicable)
Documentation Requirements
- Data processing records
- Privacy policies and notices
- Security policies and procedures

- Training records
Incident Response
Incident Types
- Unauthorized access
- Data breach or leak
- Malware or ransomware
- Account compromise
- Data loss or corruption
Response Procedures
- Detect: Identify the incident
- Contain: Limit the damage
- Investigate: Determine scope and cause
- Remediate: Fix the issue
- Recover: Restore normal operations
- Review: Learn and improve
Communication Plan
- Internal notification procedures
- Customer communication (if affected)
- Regulatory reporting (if required)
- Public relations (if necessary)
