What is ISO 28100?

ISO/IEC 28100:2009 is officially titled:

“Information technology — Security techniques — Privacy framework”

It provides a general privacy framework applicable to information and communication technology (ICT) systems, especially those using cryptographic protection like PKI or secure messaging. The standard helps define how organizations should:

  1. Identify privacy-related risks
  2. Implement controls to manage personal data
  3. Support user preferences and privacy rights
  4. Maintain compliance with privacy regulations (like GDPR)

Although the 2009 version is the current edition, ISO 28100 is often used in conjunction with ISO/IEC 27001, ISO/IEC 29100, and ISO/IEC 27701 for a more comprehensive privacy management system.

Why is ISO 28100 important?

In the digital age, protecting personal information in communication systems is vital. Mismanaged privacy can lead to:

⚠️ Data breaches

❌ Non-compliance with GDPR or local data laws

💸 Heavy regulatory fines

🧑‍💻 Loss of consumer trust

ISO 28100 offers a privacy-by-design approach for organizations developing or managing secure communication tools or services
