1 BYOD: Privacy and Security Andrew Paterson, Senior Technology Officer

2 The ICO’s mission “uphold information rights in the public interest”: Openness by public bodies: Freedom of Information Act Environmental Information Regulations Privacy for individuals: Privacy and Electronic Communications Regulations (PECR) Data Protection Act (DPA)

3 The DPA in one slide: It’s about personal data You have to use it fairly and lawfully: act reasonably You have to be open about what you do with it You have to give people access to their own data You have to keep it secure

4 A typical mobile device Portable Personal Always-on Frequently-used Internet: Wifi / cell Camera Mic NFC, Bluetooth, GPS, accelerometer OS + Apps ecosystem

5 Typical aspects of BYOD One or more of the following: –User/employee chooses, purchases, owns, maintains, or supports the device So what is the role of the Data Controller?

6 Why consider BYOD? Possible BenefitsPossible Risks Reduced hardware costIncreased support cost of diverse hardware and software More flexible and efficient working Blurring work and personal use affects privacy (email, contacts, SMS, GPS, VPN) Greater employee satisfactionWhat about those who don’t want to (or can’t) bring their own device? Data loss / fragmentation Security exploits: data leak / theft; man-in-the-middle; malware

7 When, not if?

8 Controlling BYOD Key areas to consider: 1. Policy –Does everyone know what they should (and should not) be doing? 2.Where is the personal data stored? 3.How is the data transferred? 4.How will you control and secure the device?

9 Policy Acceptable use policy Social media policy Users must understand their responsibilities Requires input from IT, HR, TU & end users How will you monitor compliance?

10 Where does data reside? Depends on what setup you choose: –Data on the device Internal or external? –Data on the organisation's network Local caching? –Cloud Private Community Public

11 How is the data transferred? How do you transfer data to devices? –3G, Wi-Fi, Wired connection –HTTP, HTTPS, VPN, other encryption –MAC address filtering –IM, Skype or similar –Cloud-based service –File transfer or email attachment –Direct connection or via proxy –USB or CD

12 How do you control and secure the device? Who owns the device? What OS is it running? (and who decides?) Who else has access to it? What else is it used for? What if it gets lost? (remote deletion?) Onward transfer of data or device itself?

13 Privacy of the user By definition, some BYOD use will be personal –May also be used by other individuals (e.g. family members) Consider how to protect the users’ privacy if you use: –a traffic monitoring tool –geo-location monitoring –data loss prevention software

14 Other legal obligations? BYOD could lead to disparate copies of data in disparate locations Data Protection: –Subject access rights –Adequate, relevant and not excessive –Accuracy Freedom Of Information: –Can you search for the data? –Can you access the data?
