OPS.1.2.4 Teleworking

Introduction

Teleworking is understood to refer to all tasks that are performed in part or entirely outside of the business premises and buildings of an employer using information and communication technology. In home-based teleworking, employees regularly alternate between a home office and the workplace of their employer on a daily or hourly basis.

Objective

The objective of this module is to protect information that is stored, processed, and transmitted during teleworking. To this end, it presents typical threats and defines special requirements for secure teleworking.

Scoping and Modelling

Module OPS.1.2.4 Teleworking must be applied to every teleworking location.

This module concentrates on the form of teleworking that occurs in the home environment (home-based teleworking). It is assumed that a secure telecommunication link is available between a given home workstation and the corresponding organisation to allow suitable information to be exchanged and data to be accessed on the organisation's servers. The requirements of this module cover the following three areas:

  • the organisation of teleworking
  • the employee's workstation computer
  • the communication link between the teleworking computer and the organisation in question

Security requirements for the infrastructure of teleworking locations are not included in this module; these are described in module INF.8 Working from Home. Requirements for non-fixed workplaces can be found in module INF.9 Mobile Workplace.

Detailed recommendations on how to configure and secure IT systems are not covered by this module. Information on this is included in SYS.2.1 General Client, as well as in the operating-system-specific modules. Other security aspects relevant to teleworking, such as for WLAN, are considered in the modules of the sublayers NET.2 Radio Networks and NET.4 Telecommunication.

If data modified during telework is not stored directly on the organisation's IT systems, the requirements for carrying out backups must be specified. Corresponding requirements are included in module CON.3 Backup Concept.

Useful Resources

The International Organization for Standardization (ISO) provides information on how to deal with teleworking in the standard ISO/IEC 27001:2013, especially in annex A, A.6.2.1 (“Mobile Device Policy”) and A.11.2.6 (“Security of Equipment and Assets Off-Premises”.

The Information Security Forum (ISF) also provides guidelines on teleworking in “The Standard of Good Practice for Information Security”, especially in Area PA2 ("Mobile Computing").

The National Institute of Standards and Technology (NIST) has published NIST Special Publication 800-46, “Guide to Enterprise Telework, Remote Access, and Bring Your Own Device (BYOD) Security”.

1. Přehled

Název Standard
OPS.1.2.4.A1 Rules on Teleworking [Supervisor, Human Resources Department] (B)

All the relevant aspects of teleworking MUST be specified. The applicable rules or a corresponding leaflet explaining the security safeguards to be considered MUST be provided to teleworkers. Contentious points MUST be clarified in employment agreements or separate agreements between the employee and employer as a supplement to their employment contract. The rules MUST be updated at regular intervals.

OPS.1.2.4.A2 Security-Related Requirements for Teleworking Computers (B)

Security-related requirements MUST be defined that IT systems must meet for teleworking.

It MUST be ensured that only authorised persons have access to teleworking computers. Moreover, teleworking computers MUST be protected so that they can be used only for authorised purposes.

OPS.1.2.4.A5 Employee Awareness and Training (B)

Employees MUST be made aware of the risks connected to teleworking by means of a guide. Furthermore, they MUST be instructed in the corresponding security safeguards of their organisation and trained in how to deal with them. Training and awareness safeguards for employees SHOULD be repeated at regular intervals.

OPS.1.2.4.A6 Creating a Security Concept for Teleworking (S)

A security concept for teleworking that describes the security objectives, protection needs, security requirements, and risks involved SHOULD be drawn up. The concept SHOULD be reviewed and updated regularly. The security concept for teleworking SHOULD be coordinated with the overall security concept of the organisation in question.

OPS.1.2.4.A7 Regulations on Using Communication Capabilities for Teleworking [IT Operation Department, Employee] (S)

Clear rules SHOULD be specified regarding which communication capabilities may be used under which general framework conditions for the purpose of teleworking. There SHOULD be rules regarding the professional and private use of Internet services when teleworking. Here, it SHOULD also be clarified whether private use is generally allowed or prevented.

OPS.1.2.4.A8 Flow of Information Between Employees and Organisations [Supervisor, Employee] (S)

A regular in-house exchange of information SHOULD be ensured between teleworking employees and organisations. All employees SHOULD be informed about changed security requirements and other security-relevant aspects in a timely manner. All the colleagues of teleworking employees SHOULD know when and where these employees can be contacted. Technical and organisational teleworking rules on the performance of tasks, security incidents, and other problems SHOULD be specified and communicated to employees.

OPS.1.2.4.A9 Support and Maintenance Concept for Teleworking Locations [IT Operation Department, Employee] (S)

A special support and maintenance concept SHOULD be drawn up for teleworking locations. This concept SHOULD specify the following aspects: contact persons for user services, maintenance dates, remote maintenance, transport of IT devices, and the introduction of standard teleworking computers. Contact persons for hardware and software problems SHOULD be named to help ensure that employees can continue to work.

OPS.1.2.4.A10 Analysis of Teleworking Location Requirements [IT Operation Department] (S)

A requirements analysis SHOULD be performed before setting up a teleworking location. It SHOULD include the hardware and software components required for teleworking locations. The requirements for each teleworking location SHOULD be agreed with the persons in charge of IT. The protection needs of the information processed at teleworking locations SHOULD always be determined and documented.
