WHAT’S YOUR DEFINITION

IS IT DEFINITIVE?

• Copiers• Faxes• Scanners• Telephones• Coffee machines

• Any device with memory capability that can be carried out.

RISK DU JOUR

HOW DO YOU GET A GRIP ON THAT?

STEP 1

Quantify the Problem• Stop.• First measure the problem• Conduct a survey• How many devices? Running what applications? • Processing, storing, transmitting: what data?• Conduct a threat / risk assessment• Draft Asset Register• Draft Risk Register

WHAT’S THE THREAT

QUANTIFY

If the definition of a threat is the "expressed potential" for a "harmful event" to happen to

your business.

"What mobile device events would be harmful to your business?

THEN WHICH APPLY?

STEP 2

Draft policies • Device ownership• Data ownership• Device liability• Data liability• Acceptable devices• Acceptable use• Acceptable applications & connections• Non-acceptable applications & connections• Minimum device security requirements• Where to report lost/stolen devices

CONSIDER…

• Mandating use of PINs to access devices• Mandating use of complex passwords to access

applications• Set max number of password failures • Set max days of non-use lock out• Specify password change interval• Prevent password reuse via password history• Set screen-lock

STEP 3

Configuration• Firewall• Anti-virus (Malware, Trojans, Spyware)• O/S Updates• Hardening• Passwords & PINs• Back end support servers• VPN dual authentication

CONSIDER…

Adding or removing root certs Configuring WiFi including trusted SSIDs, passwords, etc. Configuring VPN settings and usage Blocking installation of additional apps from the AppStore Blocking GeoLocation Blocking use of the iPhone’s camera Blocking screen captures Blocking use of the iTunes Music Store Blocking use of YouTube Blocking explicit content

STEP 4

Encryption Data Disk Document, File & Folder Laptop Port & Device Controls Removable Media & Device Email

LAYERS Data Base Encryption: Application–level encryption of

data “at rest” in data base. • Disk Encryption: Disk-level encryption for all data on the

logic or physical drive (user files, swap files, system files, page file).

• Document Encryption: Application-level encryption of data in document format (WORD/ Excel, Notebook).

• File & Folder Encryption: Application-level encryption method.

• Client Side Encryption: Application-level encryption method used by servers to encrypt data on a computer that has connected to them.

OPTIONS

Laptop Encryption: Operating system-level encryption method started at boot-up authorisation.

Port & Device Control: Monitor device usage and file transfer activity. Controls access to laptop ports, devices and wireless networks

Removable Media & Device Encryption (USB memory, CD, DVD): Read and write encrypted data on media

Email Encryption: Dual key method securing data in transit from client.

Email Gateway Encryption: Automatic encryption and decryption of sensitive emails between email gateway and receiver.
