Information Systems Security Policy

Purpose

This document describes requirements for information systems security configurations of (^Company^).

Definition

Information Systems include any software that stores or manages information that may be sensitive in nature or otherwise needing protection from unauthorized access.

Scope

This policy applies to all information systems utilized by (^Company^).

Policy

  1. The security features necessary to minimize risks to information systems must be configured in the system before it is placed into service. 
    1. There are three general roles for the staff that manage the information systems:
      1. The end-user role will use the system to store or access information.
      2. The monitoring role has read only privileges for the purpose of monitoring access and uptime.
      3. The administrator role is able to change configuration parameters. All activity by users must be recorded, as well as any other security events that may pose a threat to the system.

  2. All users of the information system must authenticate through the central repository of users using a protocol that reduces the risk of identity theft.

  3. All users must only have access to information they need to carry out their work, and no more.

  4. All information transmitted from the system must be encrypted by a strong encryption algorithm to minimize the risks of eavesdropping on the communications and man-in-the-middle attacks.

  5. The data and events recorded by the information systems must be kept in storage media that is subject to a regular backup process. The process of maintaining these backups must ensure that the information is not amended.

  6. The password of the information system's administrator user must not be shared to unauthorized personnel. If, for any reason, it is necessary to make use of the highest administrative privileges within the system, then the staff must file a request to the internal security division for the password attaching the justification for its use and completing the required forms. The password must then be reset by the highest administrator to maintain security.
