SECURE
GOVERNMENT NETWORKS
Government systems are among the prime targets
for cyber-attackers. Government systems contain
sensitive data, including those about their citizens;
they may be linked to essential services supplied
by CII operators; they are used to support a gamut
of public services including the maintenance of
national security and sustaining the economy.
Hence, the Government will spare no effort in
safeguarding its systems and networks. The
Government has undertaken, in this current term,
to work towards a goal of setting aside 8 per cent
of its ICT expenditure on cybersecurity.
The Government sector is already identified
as one of the eleven CII sectors in the national
cyber response plan.
The Government’s plans as a CII sector
lead incorporate many of the elements of
the larger national plan. They involve:
Reducing the attack surface presented by
Government systems and erecting multiple
layers of security controls and network
segmentation according to vulnerability
and need;
Expanding our capacity to detect, correlate
and analyse threats, using automation
and other technologies; and
Sharpening the skills of our incident
responders and stress-testing our
systems through more complex and
realistic attack scenarios.

Reducing
Attack Surface
The Government has put in place long-term
measures including on-going and proactive
reviews of the ICT operating environments,
to ensure that security controls are commensurate
with rapidly evolving threats. For example,
in view of the increased frequency of targeted
attacks on Government networks, the Civil
Service will separate Internet surfing from the
networks that hold classified data according
to vulnerability, exposure and need.
At the same time, the Government will continue
its approach of adopting new technologies
to deliver secure and resilient digital services.
It is also looking into risk reduction initiatives
to minimise the potential loss of citizens’ data
or prolonged outages of digital services.

Enhancing Situational
Awareness through Technology
The Monitoring and Operations Control Centre
(MOCC), Cyber-Watch Centre (CWC), and Threat
Analysis Centre (TAC) provide the Government
with cyber situational awareness of its networks.
We will continue to invest in technologies such
as analytics, automation, artificial intelligence,
and other state-of-the-art security technologies.
This will maintain the centres’ operational
excellence, to enable timely detection and
response to a cyber incident.
Preparing for
Cyber Breaches
The Government has expanded
considerable effort in building a
team of highly-skilled security incident
responders. However, we recognise
that no system is 100 per cent foolproof and breaches may still occur even
despite the best of our efforts. We will
continue to hold regular cybersecurity
exercises to stress test our procedures
and capabilities for a realistic evaluation
of our proficiency, and conduct redteaming sessions to validate the security
of our systems. The Government
will work with the sectors to ensure
that CII protection plans are in place
for expedient remediation to restore
essential services.
Cyber-Watch Centre (CWC)
The Cyber-Watch Centre (CWC)
was established by the Infocommunications Development
Authority of Singapore (IDA) in
2007 to monitor cyber threats to
government networks and provide
early warning of impending cyberattacks. To improve the detection
of malicious activities which could
affect access to online public services,
the CWC was upgraded in 2015 with
a wider range of detection capabilities
and enhanced correlation capabilities.
This is an example of a proactive
defence-in-depth security measure
to mitigate increasingly sophisticated
attacks and enhance infocomm
infrastructure security.
