Every IT system without a related disaster management plan is considered risky.
Even the most sophisticated security measures are not enough to fully exclude
the accidental or even intentionally caused outage of the IT services of an organization.
Although the probability of a full outage is low, the resultant damages would
be enormous. Because of that, it is important to assess the impacts of the outage
of IT systems. Consequences may vary as to the costs and the inconvenience caused,
depending on the duration of the outage and how critical the service is. We must
be able to recover services after the occurrence of the disaster, so we can guarantee
the continuation of the core activity of the organization. What can be the consequences
of an IT disaster?
Loss of information
Damage of security
Halt of mission critical applications
Loss of the respect of the customers (customer dissatisfaction)
Interruption of core activities
Milestones of disaster management
Several approaches and methodologies exist. The function of risk analysis is
the definition and analysis of the assets (taking into account both those of physical
nature - e.g. hardware - and those of different nature - e.g. data), then the
clarification of the level of threats (which may be accidental or intentional)
regarding these assets, and finally, as a matter related to the assets, the identification
and definition of exposed, vulnerable points. The asset-related risks can be calculated
through these three factors: the value of the assets, the threats and the level
The function of risk management is the mitigation of the vulnerability of the
assets by implementing the appropriate counter-measures. The counter-measures
can help in several ways: they may reduce the probability of the threat occurring
once again, mitigate the impact of an incident that has already occurred, detect
the occurrence of the event and they may also help with recovery.
The survey of the existing hardware / software assets may serve as a basis for
the entire planning process. A comprehensive list must be created about the hardware
and software assets of the organization, assorted by function, application and
service. The existing assets, all the components of the systems of the organization
must be surveyed.
When the threats are surveyed, it is important to assess not only the direct
environment of the IT function, but also the environment in the broader sense
of the term, since over half of the causes of disasters are external, i.e. they
occur outside the data center.
After the assessment of the services, cases should be collected about disasters
affecting similar services. All risks as well as their impacts on the activities
of the organization must be surveyed carefully and objectively. How can we prevent
service outages? The emphasis should be on prevention, rather than recovery!
Disaster management plan:
The fundamental element of Disaster management is the disaster plan. Recovery
after a system outage requires detailed and careful planning, and this is usually
no small task. The creation of an efficient recovery plan requires cooperation
between the various fields, divisions, services and service providers.
