Prerequisites¶

Completed IAM Assessment with approved findings
Executive sponsorship and budget approval
Identity platform licensing confirmed
Project plan and timeline approved
Change management process established

Procedure¶

Step 1: Implementation Planning¶

Objective: Create detailed implementation plan with risk mitigation

Activities: 1. Review assessment findings and remediation priorities 2. Define implementation phases and dependencies 3. Identify pilot groups for phased rollout 4. Document success criteria and KPIs 5. Create rollback procedures 6. Establish communication timeline

Implementation Phases: | Phase | Focus Area | Duration | |-------|-----------|----------| | 1 | Foundation (MFA, password policy) | 2-4 weeks | | 2 | Access Control (CA, RBAC) | 3-4 weeks | | 3 | Privileged Access | 4-6 weeks | | 4 | Lifecycle Automation | 4-6 weeks | | 5 | Governance & Monitoring | 2-3 weeks |

Duration: 4-8 hours

Step 2: Authentication Hardening¶

Objective: Implement strong authentication across the organization

MFA Deployment: 1. Configure MFA methods (Authenticator app, FIDO2, etc.) 2. Define MFA policies by user group 3. Enable registration campaign 4. Deploy to pilot group 5. Monitor adoption and issues 6. Progressive rollout to all users 7. Block non-MFA fallback

MFA Rollout Schedule: | Group | Timeline | MFA Method | |-------|----------|------------| | IT Admins | Week 1 | Hardware key + App | | Security Team | Week 1 | Hardware key + App | | Finance | Week 2 | App + SMS backup | | Executives | Week 2 | App + SMS backup | | All Staff | Weeks 3-4 | App + SMS backup |

Password Policy Enhancement: - [ ] Minimum 12 characters - [ ] Enable password breach checking - [ ] Remove complexity requirements (length > complexity) - [ ] Configure self-service password reset - [ ] Set appropriate expiration (or remove if MFA)

Legacy Authentication Blocking: 1. Identify legacy auth usage (reports) 2. Communicate deprecation timeline 3. Block legacy for new sign-ins 4. Migrate legacy applications 5. Full legacy auth block

Duration: 2-4 weeks

Step 3: Conditional Access Implementation¶

Objective: Deploy risk-based and context-aware access policies

Core Policies:

Policy	Scope	Conditions	Controls
Require MFA	All users	All apps	MFA required
Block legacy auth	All users	Legacy protocols	Block
Require compliant device	Corp apps	Unmanaged devices	Block or limit
High-risk sign-in	All users	High risk detected	MFA + password change
Admin protection	Admins	All locations	MFA + compliant device
Guest restrictions	Guests	All apps	Limited access

Implementation Order: 1. Report-only mode for baseline 2. Require MFA (least disruptive) 3. Block legacy authentication 4. Device compliance policies 5. Location-based restrictions 6. Risk-based policies

Testing Protocol: - [ ] Test each policy in report-only mode - [ ] Validate with pilot group - [ ] Check for user impact - [ ] Verify exclusions working - [ ] Document policy behavior

Duration: 2-3 weeks

Step 4: Privileged Access Management¶

Objective: Implement controls for privileged account security

PIM/PAM Configuration: 1. Inventory privileged roles 2. Convert standing to eligible access 3. Configure activation requirements 4. Set up approval workflows 5. Enable session auditing 6. Configure access reviews

Role Configuration: | Role | Access Type | Activation Duration | Approval | |------|-------------|-------------------|----------| | Global Admin | Eligible | 4 hours | Security team | | Security Admin | Eligible | 8 hours | IT Manager | | User Admin | Eligible | 8 hours | Self + MFA | | Helpdesk | Assigned | Standing | N/A |

Emergency Access Setup: - [ ] Create break-glass accounts (2 minimum) - [ ] Strong, unique passwords stored securely - [ ] Exclude from Conditional Access - [ ] Monitor for any usage - [ ] Document emergency procedures

Service Account Hardening: - [ ] Inventory all service accounts - [ ] Move to managed identities where possible - [ ] Implement credential rotation - [ ] Remove interactive logon - [ ] Enable detailed logging

Duration: 4-6 weeks

Step 5: Identity Lifecycle Automation¶

Objective: Automate provisioning and deprovisioning processes

HR-IT Integration: 1. Map HR system to identity provider 2. Define attribute synchronization 3. Configure automatic provisioning 4. Set up department/role-based access 5. Implement termination automation 6. Test lifecycle events

Provisioning Rules: | HR Event | IAM Action | Timing | |----------|-----------|--------| | New hire | Create account, assign base groups | Start date -1 day | | Department change | Update groups | Same day | | Title change | Review access | Same day | | Termination | Disable account | Immediate | | Termination +30 | Delete account | Automated |

Access Request Workflow: - [ ] Self-service access request portal - [ ] Manager approval workflow - [ ] Time-limited access grants - [ ] Automatic expiration reminders - [ ] Audit trail for all requests

Access Certification Setup: - [ ] Define certification scope - [ ] Configure review frequency (quarterly) - [ ] Set up reviewer assignments - [ ] Configure escalation for non-response - [ ] Enable revocation workflows

Duration: 4-6 weeks

Step 6: Monitoring and Governance¶

Objective: Implement ongoing monitoring and governance controls

Monitoring Configuration: - [ ] Enable identity protection alerts - [ ] Configure risky sign-in alerts - [ ] Set up privileged access monitoring - [ ] Enable failed authentication alerts - [ ] Configure anomaly detection

Reporting Dashboard: | Report | Frequency | Audience | |--------|-----------|----------| | MFA registration status | Weekly | IT/Security | | Risky sign-ins | Daily | Security | | Privileged access usage | Weekly | Security/Management | | Access certification status | Monthly | IT/Management | | Service account activity | Weekly | Security |

Governance Processes: - [ ] Quarterly access reviews scheduled - [ ] Policy review cadence established - [ ] Exception handling process defined - [ ] Metrics and KPIs tracked - [ ] Continuous improvement plan
