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 treat / 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?
What Applies?
Step 2 Draft policies Device ownership Device liability Acceptable devices Acceptable use Acceptable applications Minimum device security requirements Where to report lost/stolen devices Security Awareness Program
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 Back end support servers VPN dual authentication
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 Consider…

Step 4 Encryption Data Disk Document, File & Folder Laptop Port & Device Controls Removable Media & Device
Layers Data Disk Document File & Folder Client Side Laptop Port & Device Controls Removable Media & Device
Encryption Options 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 Encryption: Dual key method securing data in transit from client. Gateway Encryption: Automatic encryption and decryption of sensitive s between gateway and receiver.
