3 Section 3 – Assessment
3.1 Introduction
3.2 Description of an organisation’s tier level
This section describes the steps to be taken in a periodic review
of the completeness and effectiveness of the action that has been
taken. The outcome of this review should be a statement about
the maturity of the organisation’s own cybersecurity. It should
permit a comparison within a given sector, or across sectors.
Tiers range from partial (tier 1) to adaptive (tier 4), and describe
a growing degree of maturity. Organisations should determine
their target tier level, ensuring that their chosen level meets their
particular organisational goals.
The measures presented here to improve ICT resilience (see Section 2) remain useless if they are not implemented at company
level. It is important that those in charge understand the importance of cybersecurity issues, that the awareness of staff and
partners is raised, and that sufficient resources are planned and
made available to implement these measures. It is recommended
that an assessment of this minimum standard be conducted at
least annually, and action needed to improve resilience taken as
quickly as possible.
Security is not a static state that can be achieved. Security is
a process which must be conducted, evaluated, amended and
improved continually. Cybersecurity can no longer be ignored.
There is no time like the present to take appropriate action to
improve the resilience of your critical ICT assets.
Each of the tasks presented in Section 2 must be scored on a
scale of 0 to 4 (please refer to the scoring system set out below
in 3.2.1). These scores form the basis for an evaluation of an
organisation’s tier level (see Section 3.3).
3.1.1 Task scoring system
0 = Not implemented
1 = Partially implemented, not fully defined and adopted
2 = Partially implemented, fully defined and adopted
3 = Implemented, fully or largely implemented, static
4 = Adaptive, implemented, continuously reviewed, improved
The next section presents detailed descriptions of the four tier
levels.
3.2.1 Tier 1: partial
Tier level 1 reflects risk management processes and organisational
cybersecurity requirements which have not been formalised.
Thus, cybersecurity risks are generally managed on an ad-hoc
or reactive basis. There is an integrated risk management programme at the organisational level, but no institutionalised
awareness of cybersecurity risks or an organisation-wide approach to managing them. Typically, the organisation will not
have procedures in place to make coordinated use of information on cybersecurity. Similarly, in many cases, where cybersecurity
risks occur the organisation will not have standardised procedures by which to share information or to coordinate collaboration
with external partners.
3.2.2 Tier 2: risk informed
Organisations which classify themselves into tier 2 typically have
risk management procedures in place to counter cybersecurity
risks. However, they are not implemented in the form of specific instructions that staff must follow. At the organisational
level, cybersecurity risks are integrated into the company-wide
risk management system, and there is a certain awareness at
all levels of the business. That said, such organisations usually
lack company-wide approaches to managing and improving
awareness of current and future cybersecurity risks. Approved
procedures and processes are defined and implemented. Staff
have sufficient resources to fulfil their roles in connection with
cybersecurity. Cybersecurity information is shared within the
organisation on an informal basis. The organisation understands
its role in the broader environment and communicates with external partners (e.g. customers, suppliers, service providers, etc.)
on cybersecurity issues. There are no standardised procedures
for cooperating or for sharing information with these partners,
however.
