APT Ltd Information Security Policy

1. Introduction

Information takes a number of forms. It can be stored on computer systems, transmitted across networks, printed out, captured with a camera, written down on paper as well as spoken in conversations.

Information held and maintained within computer systems, together with any networks that support it, is a particularly important asset. Without it and the computer system on which it is maintained, an organisation may not be able to operate effectively if at all.

Security risks to computer systems are increasing from an ever widening and increasingly sophisticated range of sources. Systems may be the target of a number of threats, including fraud, sabotage, vandalism and other sources of failures as well as natural disasters such as fire and flood.

In additional, new sources of potentially damaging threats continue to emerge as well as those already posed by computer viruses and hackers. All information needs protection from both accidental and deliberate damage and using appropriate security controls and procedures can reduce these risks.

The security of data combines and covers four main areas:

Area Definition
Confidentiality Protecting information from unauthorised disclosure or interception
Integrity Protecting and ensuring the accuracy and completeness of information and computer systems
Availability Ensuring that information, resources and services, including computer systems, are available when required.
Compliance Ensuring that formalised data procedures are followed at all times in order to reduce risks and comply with any responsibilities under the Data Protection Act and other relevant legislations or regulations imposed by the UK government or regulatory bodies.

It is the policy of APT to maintain an information management system designed to meet the requirements of ISO 27001 in pursuit of its primary objectives, the purpose and the context of the organisation.

1.1. Aims and Objectives

The aim for APT in information security is to adopt best practices for the handling, processing and storage of data, ensuring all areas of confidentiality, integrity, availability and compliance are adhered to in accordance with the ISO27001 standard and other standards and requirements as set by government legislation and regulatory bodies at all levels of the business.

The broad aims of this policy and any associated policies are:

  - To prevent security breaches
  - To detect a breach if it occurs
  - To limit any damage caused by a breach
  - To recover from the effects of a breach

APT intend to achieve these objectives by communicating clear guidance to all employees, contractors and third parties that have direct access to data stored on APT’s networks and information technology systems.

1.2. Scope

This Policy and all associated policies aim to include all aspects of APT’s business practices and apply to all employees, contractors, third parties or any other individuals that have direct access, at any or for any period of time, to any networks and systems under APT’s control.
