Every business today relies on data, but data is also at risk from leaks, errors, and system failures. ISO 27001 certification gives organizations a proven way to protect information. It sets out clear ISO 27001 certification requirements that focus on three main pillars: Confidentiality, Integrity, and Availability.
These three pillars guide how data is stored, shared, and accessed. In this blog, we explain them in simple terms and show how Prowise Systems helps businesses meet the ISO 27001 certification requirements and prepare for successful certification.
1. Confidentiality
Confidentiality ensures that information is accessible only to authorized individuals. It blocks unauthorized staff, attackers, or outsiders from accessing sensitive data.
Example: In a hospital, only doctors treating a patient should see their medical history.
How ISO 27001 certification supports confidentiality
- Role-based access controls
- Multi-factor authentication
- Encryption of data and communication
- Regular audits of access rights
Following these ISO 27001 certification requirements helps organizations protect customer data and maintain trust.
2. Integrity
Integrity ensures that data remains accurate and unchanged unless it is approved. If data is tampered with, it loses its value and can lead to serious mistakes.
Example: If financial reports are altered, business leaders may make wrong decisions.
How ISO 27001 certification protects integrity
- Digital signatures and checksums
- Audit logs that record changes
- Secure backup systems
- Alerts for unusual system activity
By meeting ISO 27001 certification requirements for integrity, organizations can make informed decisions and mitigate financial and legal risks.
3. Availability
Availability ensures data is accessible to authorized users when needed. Even if data is secure and accurate, it is useless if systems are down.
Example: An e-commerce platform must keep its payment systems running at all times. Any downtime can cause lost sales and unhappy customers.
How ISO 27001 certification ensures availability
- Disaster recovery plans
- Redundant systems and backups
- 24/7 monitoring of servers
- Tested incident response processes
Strong availability controls are a key component of ISO 27001 certification requirements and are essential for maintaining business continuity.
How the Three Pillars Work Together
Confidentiality, integrity, and availability are connected. Confidentiality prevents leaks, integrity ensures accuracy, and availability guarantees access.
Example: Online banking needs all three. Accounts must remain private (confidentiality), balances must be correct (integrity), and services must always be active (availability). Meeting these ISO 27001 certification requirements gives banks and customers confidence.
