Information Security and Common Sense Richard Henson University of Worcester October2008
Why has Data Security become such a problem? • “End User” Computing • Advances in Technology • Confusion about the Data Protection Act • Lack of policy or inconsistent implementation of policy • Data handling training issues
The Rise of End User Computing • In the 1980s, organisational data was kept either in: • centralised computers • secure filing cabinets • The PC offered the possibility of organisational data in the hands of “non professionals”… • network administrators predicted there would be big problems… • few people listened… THEY SHOULD HAVE!
Where are we now with Information Technology? • Days of “mainframe” or “centralised” computing… comparable to mass transport systems (e.g. stage coach, railways, bus) • “professional” drivers • people driven about
Another e.g. of Technological Change bringing about Cultural Change… • Coming of the motor car…
The Coming of the Personal Computer… • In technology/society terms, the equivalent of the motor car…
Result of “the motor car” cultural change… • Transport became personalised • those handling motor vehicles were often a menace to other road users • many accidents, injuries, lives lost • Only controlled through the use of legislation (e.g. Highway Code) • and then more legislation (e.g. Driving Test)… • and yet more legislation!!! (e.g. National Speed Limit)
Are roads safe today? • UK Road deaths been falling consistently for many years • So a cultural problem CAN be brought under control… • What about the perils of end user computing…
Digital Data and the Law • What do we have for keeping computer users in order? • the Data Protection Act • Problem… dates back to 1984 • BEFORE end user computing • Update in 1998 • did not address the problems associated with putting the end user in control • e.g. digital data can be easily carried around
The New Law • Finally (2008) legislation is being updated to acknowledge the problem • New offence of “Data Recklessness” • Information Commissioner’s Office (ICO) has increased powers.. • further changes expected during the 2008-9 Parliamentary Session Information Commissioner Richard Thomas
Why such a long wait? • Again… back to the motor car • Highways Act? • became law in 1835 • only substantially updated in… 1959 • Why then? had become • a matter of public concern • Equally, Data Protection is now A MATTER OF PUBLIC CONCERN • latest surveys; people now as concerned about their privacy as they are about terrorism!
What are the consequences for Organisations? • They need to get serious about data protection, or risk the wrath of the Information Commissioners Office • first to suffer was… • Richard Branston, Virgin Media (3383 customer records went missing) • Would you want to be next???
What to do? • Apply common sense! • establish, or update the organisation’s Information Security Policy • key role: Data Controller - make sure all employees are aware of the law… • make sure systems are in place to make sure that policy works at operational (end user) level • make sure the systems are auditable, and regularly audited
Don’t Know where to start? • There is now an International Standard: • ISO 27001 • based on British Standard BS7799 • UK leading the world in design… • but not implementation! • any organisation achieving this quality standard gains in two crucial ways: • unlikely to lose data through “recklessness” • can use the ISO 27001 “kitemark” to show potential customers that their personal data is being properly looked after
Is getting ISO 27001cost-effective? • BIG question • even before… • “credit crunch” arrived • data recklessness became law • Cost overhead of ISO 27001 quantifiable • intensive, highly focussed courses • paperwork deliberately customisable to meet the needs of large and small organisations • If data is lost, what of the cost overhead of: • bad press? • disgruntled customers? • hefty fines?
Is good Information Security Common Sense? • YES… • just as driving safely is common sense • BUT… • What would the roads be like today if: • 1835 Highways Act was still in force unchanged? • no-one had to pass a driving test? • QUESTIONS???
