Maddison, Kirk (Kirk Maddison homegroup org uk)

In ISO/IEC 27001: 2005 A.10.4.2 (Control against mobile code) 'Mobile
Code' refers to software code or scripts that can execute with little or
no interaction from a user. When dealing with this control I typically
consider all host scripting languages that can run on client OS (e.g.
Win32: Windows Script Host, Powershell, Batch / *nix: Bash, CSH).

Things I usually consider are:

* How can mobile code be tested in an isolated environment (i.e. not a
live/production environment)?
- so admins/developers don't break things!
* Does the use of mobile code be blocked in your environment?
- usually most user do not need to run scripts, so can you block
it?
* How can you block the receipt or execution of mobile code
- Outlook has been quite vulnerable to attack, how can you
prevent mobile code landing in a users inbox?
* How can you prevent unauthorised code from executing?
- Do you need to digitally sign mobile code so that systems will
only execute trusted code?

There are more than this, the above is the tip of the iceberg! I hope
this helps.

Kirk

Subject: Control clarification

What does "mobile code" mean in the context of the control "10.4.2" -
Control against mobile code?

Does this refer to mobile malicious software like worms or some other
custom software code?
