In connection with the data systems listing, we describe for which systems we are responsible for the implementation of the backup. The organization’s own backup processes are documented and an owner is assigned to each. The documentation includes e.g.:
The media used for backups and the restoration of backups are tested regularly to ensure that they can be relied on in an emergency.
Accurate and complete instructions are maintained for restoring backups. The policy is used to monitor the operation of backups and to prepare for backup failures.
Sometimes an unexpected event, such as a fire, flood, or equipment failure, can cause downtime. In order to be able to continue operations as quickly and smoothly as possible, continuity planning is carried out, i.e. planning the operations in advance for these exceptional situations.
Each continuity plan shall contain at least the following information:
The organisation should regularly, at least annually, test and review its information security continuity plans to ensure that they are valid and effective in adverse situations.
Testing of continuity plans shall involve, as appropriate, stakeholders critical to each plan. The organisation should identify and document the necessary contacts with suppliers and partners
In addition, the adequacy of continuity plans and associated management mechanisms should be reassessed in the event of significant changes in operations.
With adequate backups, all important data and programs can be restored after a disaster or media failure. An important first step in a functional backup strategy is to identify who is responsible for backing up each piece of data. Determining the responsibility for backup is the responsibility of the owners of the information assets (systems, hardware).
If the backup is the responsibility of the partner, we will find out:
If the backup is our own responsibility, we will find out:
The organization shall have procedures in place to communicate effectively with stakeholders and other participants during continuity plans and survival procedures.
Communication plans related to continuity plans shall include:
