Agenda

5

• Cloud Computing is another way of providing IT services

• Characteristics are- Highly standardized services- Highly standardized SLAs

• Using such a service is outsourcing

• Cloud SLAs are usually much more standardized than in other outsourcing contracts

Cloud Computing is a Business model

Cloud is a deployment model

Cloud Computing is a Deployment Model

• Cloud computing is a deployment model

• Information processing- In a shared environment- using shared computing resources

• Resources can be quickly scaled to meet changed demand

• Cloud deployments are usually much more standardized and automated than legacy IT

7

Economies of Scale

• Better ROI

• Cost of security spread to all customers

High Resiliency

• Better back up services

• Better business recovery

Cloud Opportunities

Efficient solutions

• More efficient resource utilization also means cost savings

Standardised solutions

• Better patch management

• Better software update management

• Portable and interoperable

Isolation Failures

• control resides to the cloud provider

Loss of Governance

• Customer cedes some control to the provider (depending on the deployment model)

• This also affects security

Cloud Challenges

Management GUI and API compromise

• Identity and access management are particularly important

• Full access to all resources (keys to many kingdoms)

Data protection

• The CSP usually becomes data processor in terms of DP legislation

• Data processing in datacentres abroad can imply that certain DP requirements cannot be met in the Cloud

9

Public Sector

• Legacy Data

• Legacy Applications

• Legacy Processes

• Special information assurance requirements

NEEDS MORE TIME TO ADOPT

Differences in Requirements for Governments vs. Companies

Private Sector

• Difference depending on the scale i.e. Large companies and SMEs

• Investment from cost perspective

EASIER TO MAKE THE RIGHT DECISION

Cloud Computing Risk Assessment

Addressed to: public sector, private sector (large companies and SMEs), governmental agencies

13

Risk Assessment in the Cloud

Famous 2009 Guide Updated in 2012 Security Guide for SMEs – 2015

14

Security guide for SMEs

• Small and medium size enterprises (SMEs) are an important driver for innovation and growth in the EU

• Cloud Computing is a means for innovation, but cloud is for the SMEs still a challenge.

• ENISA in this study presents:

- 11 security opportunities (compared to legacy IT benefits)- 11 security risks (compared with legacy IT risks)- 12 security questions for the SME to ask the provider (in one

security “cheat sheet”- 2 comprehensive scenarios- Some legal advice

15

…and online tool

Where you can:

• rate your opportunities from cloud

• rate your risks

• produce a risks map

• get your security questions

Governmental Clouds

Addressed to: public sector, governmental agencies

Governmental Cloud reports (1/2)

2010: Guide on security and resilience for Governmental Clouds

• Presentation of the security benefits and drawbacks for the public sector to go in the cloud

• First steps need to be done towards taking the decision to go cloud

2013: Good practice guide on how to securely deploy Governmental Clouds

• Definition of a governmental cloud (in a mature market)• State of cloud computing adoption in the EU public sector• Case studies of different approaches in adopting a cloud

solution

Governmental Cloud reports (2/2)

2014: Security Framework for Governmental Clouds

• 4 phases, 10 different steps and the specific actions to be taken in each one

• 4 use case scenarios to find the solutions that better fits each implementation

19

Critical Clouds

Addressed to: private sector, (public sector in some cases)

20

ENISA’s Critical Cloud Study

• First assessment of CIIP aspects of Cloud computing

• Illustrates dependencies and provides examples for failures

• Provides recommendations for Cloud security governance from the CIIP perspective

• Conclusions can be applied to Governmental Cloud usage

21

• Cloud computing incidents could have major impact.

• Large scale incidents should be reported to improve trust

• Public sector and industry should agree on scope and thresholds of reporting.

• ENISA suggests a model for incident reporting of cloud incidents involving CSPs and regulators.

Incident Reporting for Cloud Computing

22

Critical Clouds

Cloud in the Critical Sectors

Cloud supporting Health care systems and services

Cloud supporting eGovernment

Cloud Computing in the Finance Sector

23

• Identification of critical challenges to cloud computing adoption in the Finance sector

• Assess legal and regulatory context (challenges and opportunities) in all member states

• Support industry and understand their uptake – why do some use and some don’t use cloud

• Propose recommendations

Good Practices for the use of Cloud Computing in the area of Finance Sector

24

Cloud Certification

Addressed to: private sector - large companies and SMEs, (public sector and governmental agencies in some cases)

25

The EU Cloud Strategy

“EU should not only be cloud-friendly, but also cloud–active”

“I am pleased that ETSI launched and steered the Cloud Standards Coordination (CSC) initiative in a fully transparent and open way for all stakeholders.”

“...ensuring technical security requirements are mapped onto certification, as ENISA is leading…”

“... we officially launch the platform for public sector cooperation with this "Cloud for Europe" initiative. This is an enormous step forward.…” Neelie Kroes, European Commissioner for the Digital Agenda Oct 2013

Cutting through the jungle of technical standards

Development of model “safe and fair” contract terms and conditions

A European Cloud Partnership to drive innovation and growth from the public sector

The European Commission’s

strategy “Unleashing the

potential of cloud computing in

Europe”

Adopted on 27 September 2012, it is designed to speed up and

increase the use of cloud

computing across the economy

26

ENISA realising the EU Cloud Strategy: Certification

• Strategic objective of EC Strategy: List of voluntary certification schemes

• Cloud Certification Schemes List (CCSL): List of existing certification schemes– 13 Certification schemes included– Powered by ENISA, supported by the EC

and the Cloud Selected Industry Group (C-SIG)

Visit: https://resilience.enisa.europa.eu/cloud-computing-certification

• Cloud Certification Schemes Meta-framework (CCSM): Meta-framework based on existing certification schemes– Mapping detailed ICT security

requirements of the public sector in the EU (11 countries and more will come)

– Matrix will results to be used for procurement

• EU perspective on ex post analysis (forensics) for cloud incidents: 8 countries(IT, ES, IE, NL, GR, FR, EE, UK): Academia, LEAs, Forensics Specialists, CERTs.

• Challenges, procedures, tools, legal restrictions

ICT in e-Health (2016)

• Challenges and opportunities of ICT deployments in eHealth (medical records, patient records etc)
