Agenda

• cyber threats

• corporate risk management

• anatomy of a cyber-incident


Cyber threats


Introduction to cyber security

• The economy depends on a stable, safe, and resilient

online environment

• A vast array of networks allows us to:

Communicate

and travel

Run our

economy

Power our

homes

Provide

government

services


Introduction to cyber security

Cyber attacks

have increased

dramatically over

the last decade

exposing:

Sensitive

personal and

business

information

Disrupting

critical

operations

High costs on

the economy

(estimated to

be €800 million

in Ireland)

Risk and

security in the

cloud


Cloud computing overview

• cloud computing v’s traditional delivery models

– what are traditional delivery models?

• software licensing

• remote managed service e.g. payroll

• ICT outsourcing (i.e. ICT resources given to

another to manage)


Cloud computing overview

• how does cloud computing differ?

– Internet\intranet accessible

– scalable (sometimes massively so) and user-configurable

computing resources- PaaS and IaaS

– multi-tenancy – customers share single s/w instance

– subscription or usage based payment – at least an element of pay-

for-what-you-use

– self-service model

– typically not location specific (this may change with MLE pressure)

– new concerns for the ICT security professional


The environment

• are there any norms in cloud computing?

− yes to the technical norms of service

− no to any commercial risk management or legal norms

• cloud computing risk management rule setting:

– model is commercially brutal – suppliers operate within tight commercial rulebook and accompany this with tight risk management model

– model is supplier led


Power relationship…

…is normally skewed in favour of suppliers.

Offerings are:

• without much similarity

• supplier drafted

• often carry over supplier business practices in real world business

areas (e.g. Microsoft)

• biased in favour of supplier (risk transfer point)

• typically immature in areas of risk management & liability

management from perspective of MLE but for the SaaS supplier the

logic of the business model is everything


The contract

• Queen Mary College, UL – 2011 Cloud study

• reviewed 31 contracts from 27 suppliers

• all the main suppliers contracts reviewed

• reviewed key criteria & examples:

– location of data – clear/unclear

– data confidentiality/integrity/availability – s/levels

– disputers jurisdiction – 15/31@US & 8/31@UK

– limitation of liability & remedies – s/credits & exclusions of LOL

– amending terms – by whom/how

– confidentiality/law enforcement


Enterprise risk issues

Cybersecurity

• here we look at security not as corporate operational issue but as corporate risk issue

Q: how bad can a contract be from a corporate risk management perspective?

A: so bad that by a combination of SLA and contract the supplier may have little or no responsibility and/or liability for loss\corruption of data due to its “default”

• thus – risk (being like water) flows to customer


However,

• the motives for going to the cloud are, more often than not,

financial

• the customer relies on the cloud provider to manage cyber

risk

• the provider is not contractually obligated to do so

• so cyber risk is "kicked under the carpet"


Cloud-specific cyber risk

• contracts – typically poor

• lack of visibility of security at hosting sites – audit

Q/SLA

• vulnerability to supplier IT staff

• vulnerabilities from other systems on same cloud

systems (segregation)

• JCB syndrome – dependent on comms


Cloud-specific cyber risk

• cloud provider technical failure (incl. DRP, BCP)

• cloud provider business failure – SaaS real risk

• provider Insolvency – data mess – retrieval and

ownership

• incident response restrictions

• litigation response issues

• data protection issues

• cyber insurance


Data Protection

• export of Personal Data outside the EEA only if: – consent is given to data exports; or

– the personal data is exported for the purpose of fulfilling a contract;

or

– the personal data is exported to countries which are deemed by the

EU Commission to have adequate data protection laws; or

– the company has put adequate privacy safeguards in place for the

transfer.

HOW DOES THE CLOUD PROVIDER COMPLY?

Forthcoming EU regulation


Jurisdiction?

• where is the data?

• international legal systems don't yet recognise "the

cloud". The data sits as magnetic patterns on disk

somewhere

• which is no guarantee that a large cloud provider

can find it, or keep track of its location. (Vmotion)

• issues like RAIC make things more complicated

still – where is data?


Microsoft


Incident response

in the cloud


Incident response

• Problem 1: your cloud contract may not allow you the level of

access you need to carry out a proper investigation

• Problem 2: your cloud provider may be unable / unwilling to

cooperate

• Problem 3: you may simply not have the search capacity /

bandwidth to find what you need

• In common law you must discover all relevant material in your

power, possession or procurement
