The cybersecurity architecture should comply with the NIST
Framework Core. It must offer protection for the confidentiality, integrity and availability of data, services and systems. An
implementation plan should be drawn up for the cybersecurity
architecture. This should be designed with the specific corporate
culture and the business’s strategic objectives in mind, but at the
same time pay appropriate heed to the need for security, and
the resources that this requires. The cybersecurity architecture
is generally accompanied by an integrated task list which identifies expected outcomes (indications and triggers for further
review and orientation), determines project timelines, supplies
estimates of the required resources, and pinpoints significant
project dependencies.
To meet the requirements for information security, physical assets,
including systems and network equipment, office equipment
(e.g. network printers and multifunction devices), as well as special equipment (e.g. industrial control systems) must be protected
for their entire life cycle, from acquisition (purchase or lease),
through maintenance, to their disposal.
Mobile devices (including laptops, tablets and smartphones) and
their data must also be protected against unauthorised access,
loss and theft, by configuring their security settings appropriately, limiting access to them, installing security software, and
managing all devices centrally.
1.6.8 Hardware life cycle management
1.6.7 Physical security
Physical security measures reduced the risk of accidental or
deliberate loss or damage to ICT assets belonging to the organisation or the surrounding environment. The assets to be protected
include physical assets such as tools and plant equipment, the
environment, the surrounding community and intellectual property, including proprietary data, such as process settings and
customer information. In many cases, physical security controls
must meet specific environmental, safety, regulatory, legal and
other requirements. Organisations should tailor physical security
controls, such as technical controls, to the type of protection
needed. To ensure comprehensive defences, physical protection
also covers the security of ICT components and data from the
surrounding environment which is connected with the ICT. With
many ICT infrastructures, security is closely linked to plant safety.
This is to keep employees out of dangerous situations, without
obstructing them in their work, or emergency procedures. Physical security controls are both active and passive measures which
limit physical access to all elements of the ICT infrastructure.
Below are a few examples of the incidents that such defences
are intended to prevent:
• Unauthorised physical access to sensitive locations
• Physical modification, manipulation, theft or other removal
or destruction of existing systems, infrastructure, communications interfaces or physical locations
• Unauthorised observation of sensitive facilities through
visual observation, photographs, or any other means of
recording information
• The unauthorised introduction or installation of new systems,
infrastructure, communications interfaces or other hardware
• The unauthorised introduction of devices (USB sticks, wireless
access points, bluetooth or mobile devices) designed to
manipulate hardware, listen in on communications, or
have any other damaging effect.
The acquisition (purchase or lease) of durable, reliable hardware
should always conform to security requirements. Possible vulnerabilities in the hardware should always be identified.
The aim is to ensure that the hardware always offers the
required level of functionality, and does not impair the security
of critical or sensitive information and systems for the whole of
its life cycle.
1.6.9 Mobile device configuration
To protect data from unauthorised access, loss and theft, mobile
devices (including laptops, tablets and smartphones) should
always have a standard configuration which confirms to the
security requirements.
The aim of this standard configuration is to guarantee the
information security of stored or transmitted data on the mobile
device, even if it is lost or stolen.
1.6.10 Industrial control systems
Industrial control systems must be monitored and controlled in
accordance with the level of protection that they require. These
systems demand particular technological and physical protection,
specifically in order to guarantee that supply-related processes
continue to run.
