Introduction
single
Formatted: Font color: Custom Color(RGB(33;29;30))

The focus of this document is to address Internet security issues and provide guidance for addressing

common Internet security threats, such as:
— social engineering attacks;
— zero-day attacks;
— privacy attacks;
— hacking; and

— the proliferation of malicious software (malware), spyware and other potentially unwanted

software.
Formatted: Font: Not Bold

The guidance within this document provides technical and non-technical controls for addressing the

Internet security risks, including controls for:
— preparing for attacks;
— preventing attacks;
— detecting and monitoring attacks; and
— responding to attacks.

The guidance focuses on providing industry best practices, broad consumer and employee education to

assist interested parties in playing an active role to address the Internet security challenges. The

document also focuses on preservation of confidentiality, integrity and availability of information over

the Internet and other properties, such as authenticity, accountability, non-repudiation and reliability

that can also be involved.
This includes Internet security guidance for:
— roles;
— policies;
— methods;
— processes; and
— applicable technical controls.

Given the scope of this document, the controls provided are necessarily at a high-level. Detailed

technical specification standards and guidelines applicable to each area are referenced within the

document for further guidance. See Annex A for the correspondence between the controls cited in this

Formatted: cite_app
document and those in ISO/IEC 27002.
Formatted: cite_app

This document does not specifically address controls that organizations can require for systems

Formatted: std_publisher

supporting critical infrastructure or national security. However, most of the controls mentioned in this

Formatted: std_docNumber
document can be applied forto such systems.

Foreword

ISO (the International Organization for Standardization) and IEC (the International Electrotechnical

Commission) form the specialized system for worldwide standardization. National bodies that are

members of ISO or IEC participate in the development of International Standards through technical

committees established by the respective organization to deal with particular fields of technical

activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international

organizations, governmental and non­governmental, in liaison with ISO and IEC, also take part in the

work.

Introduction

The focus of this document is to address Internet security issues and provide guidance for addressing

common Internet security threats, such as:
— social engineering attacks;
— zero-day attacks;
— privacy attacks;
— hacking; and

— the proliferation of malicious software (malware), spyware and other potentially unwanted

software.

The guidance within this document provides technical and non­technical controls for addressing the

Internet security risks, including controls for:
— preparing for attacks;
— preventing attacks;
— detecting and monitoring attacks; and
— responding to attacks.

The guidance focuses on providing industry best practices, broad consumer and employee education

to assist interested parties in playing an active role to address the Internet security challenges. The

document also focuses on preservation of confidentiality, integrity and availability of information over

the Internet and other properties, such as authenticity, accountability, non-repudiation and reliability

that can also be involved.
This includes Internet security guidance for:
— roles;
— policies;
— methods;
— processes; and
— applicable technical controls.

Given the scope of this document, the controls provided are necessarily at a high-level. Detailed

technical specification standards and guidelines applicable to each area are referenced within the

document for further guidance. See Annex A for the correspondence between the controls cited in this

document and those in ISO/IEC 27002.

This document does not specifically address controls that organizations can require for systems

supporting critical infrastructure or national security. However, most of the controls mentioned in this

document can be applied to such systems.

This document uses existing concepts from ISO/IEC 27002, the ISO/IEC 27033 series, ISO/IEC TS 27100

and ISO/IEC 27701, to illustrate:

— the relationship between Internet security, web security, network security and cybersecurity;

— detailed guidance on Internet security controls cited in 9.2, addressing cyber-security readiness for

Internet-facing systems.

ISO/IEC FDIS 27032:2023(E)

Figure 1 — Relationship between Internet security, web security, network security and

cybersecurity

The Internet is a global system of inter-connected digital networks in the public domain. The

information exchange on the Internet also uses the mobile telephony network that is hence part of the

Internet. This global network connects billions of servers, computers, and other hardware devices. Each

device is connected with any other device through its connection to the Internet. The Internet creates

an environment which is conducive to information sharing.

Internet security is concerned with protecting Internet-related services and related ICT systems and

networks as an extension of network security. These efforts aim to reduce Internet related security

risks for organizations, customers and other relevant stakeholders.

Internet security also ensures the availability and reliability of Internet services. Over the Internet,

various services are on offer, such as file transfer services, mail services or any services that can be

publicly shared with the end users. In this context, Internet security deals with the secure delivery of

these services over the public network.

The web is one of the ways information is shared on the Internet [others include email, file transfer

protocol (FTP), and instant messaging services]. The web is composed of billions of connected digital

documents that can be viewed using a web browser. A website is a set of related web pages that are

prepared and maintained as a collection in support of a single purpose.

Web security deals with information security in the context of world wide web (WWW) and with web

services accessed over the public network. The web service is enabled by the use of HTTP protocol in

which any registered publicly available URL can be accessed. Web security also deals with security of

this HTTP connection used for information exchange.

A network can include components such as routers, hubs, cabling, telecommunications controllers,

key distribution centres, and technical control devices. Network security broadly covers all kinds of

networks that exist within an organization from local area network, wide area network, personal area

network and wireless networks.

---------------------- Page: 12 ----------------------
ISO/IEC FDIS 27032:2023(E)

Network security is concerned with the design, implementation, operation and improvement of

networks, as well as the identification and treatment of network-related security risks within

organizations, between organizations, and between organizations and users.

Cybersecurity concerns managing information security risks when information is in digital form in

computers, storage and networks. Many of the information security controls, methods, and techniques

can be applied to manage cyber risks.

Cybersecurity also deals with protecting Internet-connected systems including hardware, software,

programs and data from potential attacks. Many of these attacks are characterized by targeted and

blended attacks with a high degree of sophistication and persistence. The threats can be Internet­

based and/or threats due to connectivity with other networks and systems within the organization or

customer and service provider’s network, to which the organization communicates during the normal

course of business.
6 Overview of Internet security

The personally identifiable information (PII) of Internet users is captured by many sites and services

offered on the Internet. This includes application service providers who closely track user activities and

use artificial intelligence (AI) techniques to provide recommendations for purchases, healthcare, time

management and a host of other feedback intending to make their lives and tasks easier to manage. Many

of these sites collect this data without the users’ permission and provide this data to other third parties

for monetary gain, again without the users' knowledge. In
