ISF Threat Horizon for 2017
1. Disruption divides and conquers
1.1. Supercharged connectivity overwhelms defences
1.2. Crime syndicates take a quantum leap
1.3. Tech rejectionists cause chaos
2. Complexity conceals fragility
2.1. Dependence on critical infrastructure becomes dangerous
2.2. Systemic vulnerabilities are weaponised
2.3. Legacy technology crumbles
2.4. Death from disruption to digital services
3. Complacency bites back
3.1. Global consolidation endangers competition and security
3.2. Impact of data breaches increases dramatically

Current Cyber Security situation
 The most important task for a system responsible is to ensure reliable and safe
operation of the system
 But due to more IT automation, cyber attacks are now a bigger threat to this
then ever before
 It has therefore become impossible to only trust on the vendor to guarantee
safe and secure system operation, end user validation is needed
 Perfect security is not realistic, but what is needed is a good grip in respect to
understanding the risk and impact of the network’s vulnerabilities
The evolvement of technology causes new vulnerabilities for the energy system

Cyber Security End-To-End Test
Comprehensive, cost effective testing for energy IT systems and smart grids

The service will provide 3rd party
technical validation services to provide
bottom up proof that proper security
measures have been taken for a
complete system from an end to end
perspective.
Periodic evaluation
We assess your system regarding
–
Secure network design principles.
–
Physical cyber defences and
intrusion prevention.
–
In-depth data stream analysis.
–
Policy and procedures for
prevention, detection, mitigation
and recovery.

End to end testing
Device testing
High Level Findings from the pilot tests
 Physical security, network security and security
procedures are handled by different
departments
– Little alignment in between
 Networks are often not configured correctly by
the vendor, if turn key solutions are provided.
E.g.: unused enabled switch ports, 3rd party
vendor access unbeknown to the end-user, open
webservers and telnet listeners
 There is little or no detection possibility of
suspicious activity on a industrial network
 Firewalls are absent, or configuration has not
been maintained
 We find viruses (trojans) on isolated control
systems
 Emergency procedures in case of cyber
attacks usually do not exist for SCADA,
nobody knows what to do or who to call if
they see something suspicious going on

Sannsynlighet er vanskelig…
• Sannsynlighet for angrep er vanskelig i
risikoanalyser
• Et alternativ er å fokusere på sannsynlighet
for at et angrepsforsøk lykkes

Hva bør prioriteres for å komme et steg videre?
Undersøk egen
sikkerhetstilstand
Sikkerhet må bygges
bedre inn
Det må investeres mer i
deteksjon og reaksjon
