ISO 27001 Readiness in 90 Days: A Pragmatic Path

ISO 27001 certification doesn't have to take two years and cost hundreds of thousands of dollars. With the right approach, Australian businesses can achieve audit readiness in 90 days while building genuinely valuable security practices.

Here's how to do it without the traditional consulting circus.

Why 90 Days?

Most organisations get stuck in "analysis paralysis"—spending months creating perfect documentation that nobody reads. Our approach focuses on:

Rapid implementation of essential controls
Practical documentation that serves your business
Real security improvements, not just paperwork
Australian-specific compliance considerations

The 90-Day Framework

Phase 1: Foundation (Days 1-30)

Week 1: Assessment and Scoping

Define your Information Security Management System (ISMS) scope
Conduct a rapid risk assessment using simplified templates
Identify your most critical information assets
Map existing security controls to ISO 27001 requirements

Week 2: Leadership and Policy

Secure executive commitment (non-negotiable for success)
Draft your Information Security Policy
Establish the ISMS team with clear responsibilities
Create your risk management framework

Week 3-4: Essential Controls Implementation

Implement access control procedures
Set up security awareness training
Establish incident response procedures
Begin vulnerability management processes

Phase 2: Controls and Documentation (Days 31-60)

Week 5-6: Technical Controls

Network security configuration
Endpoint protection deployment
Backup and recovery procedures
Cryptography and key management

Week 7-8: Operational Controls

Supplier security assessment
Change management procedures
System monitoring and logging
Physical security measures

Phase 3: Testing and Optimization (Days 61-90)

Week 9-10: Internal Audit

Conduct your first internal audit
Test incident response procedures
Review and refine documentation
Address identified gaps

Week 11-12: Management Review and Preparation

Management review of the ISMS
Pre-certification audit preparation
Final documentation review
Staff training and awareness completion

Essential Documents (Streamlined Approach)

Instead of creating hundreds of documents, focus on these essentials:

Mandatory Documents

Information Security Policy
Risk Assessment and Treatment Plan
Statement of Applicability (SoA)
Internal Audit Program
Management Review Records

Practical Procedures

Access Control Procedure
Incident Response Plan
Backup and Recovery Procedure
Business Continuity Plan
Supplier Security Assessment

Evidence Records

Risk register with treatments
Training records
Incident logs
Audit findings and actions
Management review minutes

Australian-Specific Considerations

Privacy Act Alignment

Ensure your ISMS addresses Australian Privacy Principles:

Data breach notification procedures
Privacy impact assessments
Cross-border data transfer controls
Individual access request handling

Essential Eight Integration

Map Essential Eight controls to ISO 27001 requirements:

A.12.2.1 (Controls against malware) → Essential Eight #1, #4
A.12.6.1 (Management of technical vulnerabilities) → Essential Eight #2, #6
A.9.4.2 (Secure log-on procedures) → Essential Eight #7

Regulatory Considerations

Australian Government Information Security Manual (ISM) alignment
Industry-specific regulations (APRA, TGA, etc.)
Critical Infrastructure protection requirements

Common Pitfalls to Avoid

Over-Documentation

Mistake: Creating elaborate procedures that nobody follows Solution: Keep documents practical and actionable

Scope Creep

Mistake: Including everything in your initial ISMS scope Solution: Start small, demonstrate success, then expand

Technology Over Process

Mistake: Buying expensive tools without proper procedures Solution: Establish processes first, then support with appropriate technology

Ignoring Culture

Mistake: Treating ISO 27001 as a compliance exercise Solution: Build security awareness and culture from day one

Resource Requirements

Internal Team (Part-time commitment)

ISMS Manager: 50% time allocation
IT Administrator: 25% time allocation
HR Representative: 10% time allocation
Executive Sponsor: 5% time allocation

External Support

Risk Assessment: 5-10 days consulting
Gap Analysis: 3-5 days consulting
Internal Audit Training: 2 days
Pre-audit Review: 3-5 days consulting

Technology Investments

Security Information and Event Management (SIEM): $500-2000/month
Vulnerability Management: $1000-3000/month
Backup Solution: $200-1000/month
Security Awareness Training: $5-15 per user/month

Success Metrics

Track your progress with these KPIs:

Security Metrics

Number of implemented controls (target: 80% of applicable controls)
Risk reduction percentage (target: 60% reduction in high/critical risks)
Incident response time (target: less than 4 hours for high severity)
Staff security awareness completion rate (target: 100%)

Process Metrics

Document completion rate
Internal audit findings closure rate
Management review action completion
Training completion rates

Measure and communicate value to maintain executive support
Continuously improve based on monitoring and review results
Keep it simple and focused on real security improvements

Getting Help

While this 90-day approach is achievable, having experienced guidance can significantly increase your chances of success. Look for consultants who:

Understand Australian regulatory environment
Focus on practical implementation over documentation
Have experience with similar-sized organisations
Offer training and knowledge transfer, not just consulting
