2. Outline • ISER • Description of ISO27001 • Effects of achieving ISO27001 certification • Costs • Benefits • Caveats • Concluding thoughts

3. Institute for Social and Economic Research • Interdisciplinary socio-economic research department at the University of Essex • ~80 staff, ~40 PhD students • Specialise in longitudinal research and methodology • Large number and variety of projects ranging from small, ad hoc studies to large, relatively permanent fixtures, e.g.: • British Household Panel Survey • Understanding Society • ESRC Research Centre on Micro-Social Change • EUROMOD • Completely dependent on research income from clients and funders. • ESRC, EC, Government Departments, foundations, commercial and charitable organisations, etc. • Certified to ISO27001 in April 2013

4. ISO27001. What is it? • ISO/IEC 27001. Information technology – Security Techniques – Information security management systems – Requirements. Second Edition. 2013-10-01. • Information security – ‘preservation of confidentiality, integrity and availability [the CIA] of information’ (ISO27000) • Confidentiality important, butnot everything • An information securitymanagement standard, not an information security standard • Framework and process for developing an information security management system (ISMS) • Tells you how to go about protecting your information, not what you should do to protect it • Wide applicability • ISO27002 provides implementation guidance • BS ISO/IEC 27002:2013. Information technology. Security techniques. Code of practice for information security controls

5. Structure • Preliminary clauses • Mandatory clauses • Information security controls

6. Mandatory Clauses • N = 7 • Common to other ISO management standards

7. Information Security Controls • Annex A. Reference control objectives and controls • N = 114 grouped into 14 sections • Maps to controls and references described in ISO 27002 • A.5.* to A.18.* • Selected as a result of the risk assessment process and recorded as applicable or not in Statement of Applicability (SOA) – clause 6.1.3

8. ISO 27001. Annex A

9. ISO27001. Costs • The standard(s) • 27001 is crucial, but also 27002 and others in 27* series • From British Standards Institute (50% discount for members) • Personnel • Designated person with overall IS responsibilities and other personnel with newly defined responsibilities • Additional meetings, e.g. regular management review, internal/external audits • Regular access/operational reviews, risk assessments • Training • New procedures created/some procedures now more formalised - more time consuming • Consultants • (Continued re-) Certification • (re) Certification Audit(s) • Certificate(s) • Surveillance audits

10. ISO27001. Benefits • Competitive advantage • ISO27001 certification is increasingly required or positively encouraged by potential clients • Assists in establishing compliance with other standards and requirements, e.g. HMG Security Policy Framework • Culture change • Increasing awareness of importance of information security in an interconnected world • Expenditure on information security increasingly seen as business investment and enabler rather than technical overhead that inhibits achievement of business goals • Information security management increasingly seen as everyone’s responsibility and not solely within the purview of the IT department • More confidence that we are meeting our ethical, legal and contractual responsibilities

11. ISO27001. Benefits (continued) • Improved – and continually improving - business and technical processes • Forced into better understanding of organisational functions and operations • Impossible not to improve – 27001 forces you to continually reassess and requires you to demonstrate improvement

12. ISO27001. What are the costs? • Can’t completely distinguish marginal costs of achieving ISO27001 certification from: • Costs of achieving good information security practice and contribution of 27001 certification to that end • Efficiency gains from the formalisation and regular review of procedures • Costs of implementing contractual requirements (other than 27001 certification) that would otherwise be required

13. Caveats • When speaking to suppliers • ISO27001 is not last word in information security • Certification verifies compliance with the standard, not with specific measures that you might feel necessary • Scope and SOA are critical • Beware of excessive claims by suppliers about the relevance of ISO27001 certification • Beware of compliance claims not backed up by (plans for) certification • Certification is marginal cost after achieving compliance and • When working towards certification • Beware of template solutions and consultants who offer them • Leads to unnecessary and irrelevant documentation • Don’t aim for perfection • ISO27001 expects continual improvement • Certification is long-term commitment • Initial certification is followed by (bi)annual surveillance audits and recertification every 3 years • Losing certification will cost a lot more than acquiring it in the first place

14. Concluding Thoughts • Jump before you’re pushed

15. Getting Help • Online resources • BSI – ISO/IEC 27001 Information Security resources (http://www.bsigroup.com/en-GB/iso-27001-information-security/Resources-for-ISO-27001/) • ECSC – ISO 27001 Executive Brief and email briefings (http://www.ecsc.co.uk/papers.cgi?id=3) • Information Security Standards (http://www.iso27001security.com/) • And others … • Training • BSI (http://www.bsigroup.com/) • SGS (http://www.sgs.co.uk/) • And others …
