5.6.
MANAGING INCIDENTS AND
UNDERSTANDING THE THREAT
5.6.1. The number and severity of cyber
incidents affecting organisations across
the public and private sector are likely
to increase. We therefore need to define
how both the private sector and the public
engage with the Government during a
cyber incident. We will ensure that the
UK Government’s level of support for
each sector – taking into account its
cyber maturity – is clearly defined and
understood. The Government’s collection
and dissemination of information about
the threat must be delivered in a manner
and at a speed suitable for all types
of organisation. The private sector,
government and the public can currently
access multiple sources of information,
guidance and assistance on cyber security.
This must be simplified.
5.6.2. We must ensure that the
Government offering, both in response
to incidents, and in the provision of
guidance, does not exist in isolation, but
in partnership with the private sector. Our
incident management processes should
reflect a holistic approach to incidents,
whereby we learn from partners and
share mitigation techniques. We will also
continue to use our relationships with other
Computer Emergency Response Teams
(CERTs) and our allies as an integrated part
of our incident management function.
5.6.3. Current incident management
remains somewhat fragmented across
government departments and this strategy
will create a unified approach. The NCSC
will deliver a streamlined and effective
government-led incident response function.
In the event of a serious cyber incident,
we will ensure that the Armed Forces are
able to provide assistance, whether in a
conventional form addressing the physical
impact of an incident, or in the form of
National Cyber Security Strategy 2016
specialist support from regular or reserve
cyber personnel. While we will provide
all the support our resources will allow,
the Government continues to stress the
importance of industry, society and the
public acting to safeguard their basic
cyber security.
Objectives
5.6.4. Our objectives are as follows:
• the Government will provide a single,
joined-up approach to incident
management, based on an improved
understanding and awareness of the
threat and actions being taken against
us. The NCSC will be a key enabler, as
will partnership with the private sector,
law enforcement and other government
departments, authorities and agencies;
• the NCSC defines clear processes
for reporting incidents, tailored to the
profile of the victim; and
• we will prevent the most common
cyber incidents, and we will have
effective information-sharing
structures in place to inform
‘pre-incident’ planning.
Our approach
5.6.5. It is the responsibility of organisation
and company management, in both the
public and private sector, to ensure their
networks are secure and to exercise
incident response plans. In the event of
a significant incident, the Government
incident management process will reflect
the three distinct elements of a cyber
incident: the precursor causes, the incident
itself and the post-incident response.
5.6.6. To deliver incident management
that is effective for both government
and the private sector, we will work
closely to review and define the scope
of the Government response to ensure it
