Varautuminen häiriötilanteisiin

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:

• Event for which the plan has been made
• Goal for recovery time
• Responsible persons and related stakeholders and contact information
• Planned immediate actions
• Planned recovery steps

Tiedonhallintayksikön on suoritettava olennaiset riskiarvioinnit sen tietoaineistojen käsittelyn, tietojärjestelmien hyödyntämisen ja toiminnan jatkuvuuden suhteen. Riskiarvioinnin perusteella tiedonhallintayksikön on:

a) Laadittava valmiussuunnitelmat ja etukäteisvalmistelut häiriötilanteiden varalle.

b) Suoritettava muut tarvittavat toimenpiteet, jotta tietoaineistojen käsittely, tietojärjestelmien hyödyntäminen ja niihin perustuva toiminta voivat jatkua mahdollisimman häiriöttömästi normaaliolojen häiriötilanteissa sekä valmiuslaissa (1552/2011) tarkoitetuissa poikkeusoloissa.

The organisation has identified the tasks that are critical for the continuity of its operations. Alternative courses of action for specific exceptional situations and staff availability and contingency arrangements have been planned and prepared for the continuation of critical tasks.

To implement the continuation plans, the plan owners, their alternates and other persons required to implement the plan have been identified. In addition, their ability to carry out their tasks under normal circumstances has been ensured.

The organization shall establish a incident response plan for security incidents to critical information systems. Response plans should also be tested by the necessary organizational elements. The plan should take into account at least:

• The purpose of the information system and the precautions to be taken in the event of its disruption
• Recovery plans, targets, and priorities for the order of recovery of assets
• The role of implementing the response plans and the contact details of the persons assigned to the roles
•  Continuation of normal operations regardless of the state of the information systems.
• Distribution, approval and review of response plans

In addition, the plan should at least:

• Establish a roadmap for developing disruption management capacity
• Describe the structure and organization of incident management capability
• Provides metrics to measure incident management capability

The organization must test and update its response to the security breach at scheduled intervals or after significant changes. For critical parts of the organization, operational plans should be tested at least annually. Test results should be documented and communicated to improve the plan.

The organization must document in advance procedures for responding to security breaches to ensure the actions of related departments, customers, and other critical partners in the event of a security breach.

Management shall define responsibilities and establish procedures to ensure an effective and consistent response to security incidents.

Management must ensure e.g.:

• interference management has clear responsibilities
• there is a documented process for responding, handling and reporting incidents

The process must ensure e.g.:

• staff have a clear contact point / tool and instructions for reporting incidents
• the reported security breaches will be addressed by qualified personnel in a sufficiently comprehensive manner
