  • REASONS FOR BLOCKING CLOUD STORAGE• Files leave the corporate network – you lose control• Files may not be backed up• Files obtained from online storage may contain malware• Files obtained from online storage may have copyright• Some Terms of Use state that they now own the rights to any document you upload
  • SECURING HOSTED APPLICATIONS• Penetration Testing • City of London’s first hosted pen test • Agreement in place (signed by the right people) • What are you allowed to test and how far? • Business decision based on results • Repeat pen test periodically
  • SECURING HOSTED APPLICATIONS• Some vendors will not allow you to do pen testing• Review policies• Find out what their physical security is like• Determine who has access to your data• Get everything in writing (preferably in a contract before services are purchased)
  • CLOUD COMPUTING AND RISK MANAGEMENT• IBM and Microsoft cloud solutions are probably more secure than most municipalities• It comes down to Risk Management• Contracts and Underpinning Contracts• Service Level Agreements/Availability• Capacity and Bandwidth Management• Policies• Data Ownership
