A related work by Microsoft is BrowserShield, an inline reference
monitor for JavaScript:

Immutable servers are nice -- let's deploy them. Yet, in an execution
environment where code is data and data is code, high assurance
software will also require control-flow integrity in the face of
malicious input. Or, what we would be left with are weird machines
instantiated from disposable images.

[SC-L] Aedificatoria: Layered Weak Links

2011-03-25 Thread Alfonso De Gregorio
Greetings SC-L,

I've recently kicked off Aedificatoria, a column on security
architectures and architecting security.
Articles - sometimes op-ed - will be aimed at addressing:
- our working landscape (with its tools, objects, technologies,
processes, and challenges);
- the architecture, as the set of theoretical and practical knowledge
driving our activities;
- ourselves and the human element.

Without further ado, the first victim of the column is Defense in
Depth and its relationship with survivability and mission assurance:

  Layered Weak Links - The Ability to Refresh Attack Cost is Key to
  Mission Success, but Seldom Available:
  http://plaintext.crypto.lo.gy/article/437/aedificatoria-layered-weak-links

As always, I very welcome your feedback and, if you feel inclined,
your guest posts. It is your contributions which will make
Aedificatoria an edifying space.

Ciao,
alfonso
