Full title and description

ISO/IEC 27033-1:2015 — Information technology — Security techniques — Network security — Part 1: Overview and concepts. Provides an accessible overview of network security concepts and definitions and gives management guidance on identifying network security risks, defining requirements and understanding the controls and architectures addressed in the other parts of the ISO/IEC 27033 series.

Abstract

Part 1 defines and describes the concepts associated with network security and offers management-level guidance. It explains the scope of network security (devices, management activities, applications/services, end users and information in transit), how to identify and analyse network security risks, how to derive network security requirements, and it provides an overview and road map of controls and technical-security-architecture topics covered in subsequent parts of ISO/IEC 27033.

Scope

This part provides an overview of network security and the associated terminology; it is intended for anyone involved in owning, operating or using networks (including senior/non-technical managers as well as technical staff). It covers guidance for identifying and analysing network security risks, defining network-security requirements from that analysis, an overview of supporting technical and non-technical controls, and introductory guidance on designing, implementing, operating and monitoring network technical security architectures — serving as a road map to the more detailed guidance in the remaining parts of the ISO/IEC 27033 series.

Key topics and requirements

• Definitions and key concepts for network security (scope includes devices, applications/services, management, end‑users and data in transit).
• Management guidance for identifying and analysing network security risks and deriving security requirements.
• Overview of technical and non-technical controls that support network security architectures.
• Guidance on achieving quality network technical security architectures: risk, design and control aspects.
• Reference scenarios and mapping to more detailed controls and implementation guidance in later parts of the 27033 series.

These topics are presented at a level intended to guide policy makers, architects and implementers toward appropriate detailed guidance in ISO/IEC 27033‑2 to 27033‑7.

Typical use and users

Used by senior managers, information security managers, network architects, network and systems administrators, IT auditors, security consultants and others responsible for planning, designing, implementing or overseeing network security. Part 1 is particularly useful as a management-level introduction and a roadmap to the more technical parts of the series.

FAQ

Q: What is this standard?

A: ISO/IEC 27033-1:2015 is the introductory part of the ISO/IEC 27033 series that defines network-security concepts and provides management guidance and a road map to the series' detailed technical guidance.

Q: What does it cover?

A: It covers definitions, the scope of network security, guidance on identifying and analysing network security risks, deriving network security requirements, an overview of supporting controls and introductory guidance on designing, implementing and monitoring network technical security architectures.

Q: Who typically uses it?

A: Senior managers, security managers, network architects, administrators, implementers, auditors and consultants — anyone involved in owning, operating, securing or designing networked environments. Part 1 is useful as a management and planning reference.

Q: Is it current or superseded?

A: ISO/IEC 27033-1:2015 (Edition 2) was published on 10 August 2015 and, according to ISO's lifecycle records, was reviewed and confirmed (remains current). For the official lifecycle status and any later reviews or amendments check the issuing body.
