What is EN ISO 27156:2011?

EN ISO 27156:2011, also known as ISO/IEC 27156:2011, is an international standard that provides guidelines for managing information security risks in the telecommunications industry. It specifically focuses on the security management of outsourcing relationships between organizations and their service providers.

Understanding the Scope and Purpose

The standard sets out to address the unique challenges associated with managing information security risks in a telecommunications context. It emphasizes the need for organizations to establish effective controls and procedures when outsourcing their information processing, storage, and transmission activities. By doing so, it aims to ensure the confidentiality, integrity, and availability of information assets throughout the outsourcing lifecycle.

Main Principles and Requirements

EN ISO 27156:2011 follows a risk-based approach to information security management in telecommunications outsourcing. It outlines key principles and requirements that organizations should consider when establishing and maintaining secure outsourcing relationships:

Context establishment: Organizations must define the scope, objectives, and constraints of the outsourcing relationship. This includes identifying the specific information security requirements and protocols.

Risk assessment and treatment: A comprehensive risk assessment should be performed to identify potential threats, vulnerabilities, and impacts associated with outsourcing activities. Appropriate risk treatment measures must then be implemented to mitigate these risks.

Service provider selection: Organizations are required to select service providers based on their ability to meet the identified information security requirements. This process involves evaluating providers' capabilities and conducting due diligence.

Relationship establishment and maintenance: Once a service provider is selected, organizations should establish and maintain a robust contract that clearly defines their respective roles and responsibilities. Regular monitoring and review of the relationship are also essential.

Performance evaluation and improvement: Organizations need to continually assess and evaluate the effectiveness of the outsourcing relationship in meeting information security objectives. Feedback loops and improvement mechanisms should be established.

The Benefits of EN ISO 27156:2011 Implementation

By adhering to the guidelines set out in EN ISO 27156:2011, organizations can achieve numerous benefits:

Enhanced information security: The standard provides a framework for robust information security management throughout the outsourcing lifecycle, reducing the likelihood of security incidents and breaches.

Informed decision-making: By conducting comprehensive risk assessments and due diligence on service providers, organizations can make more informed decisions regarding their outsourcing relationships.

Regulatory compliance: Implementing the standard helps organizations meet the regulatory requirements governing information security in the telecommunications industry.

Improved customer confidence: Organizations that demonstrate adherence to internationally recognized security standards can enhance customer trust and confidence in their services.

In conclusion, EN ISO 27156:2011 is a crucial standard for managing information security risks in telecommunications outsourcing. By following its principles and requirements, organizations can establish and maintain secure outsourcing relationships, ensuring the protection of their information assets.
