    Two tools which have become the norm in Linux- and Unix-based environments are SSH for secure communications, and sudo for performing administrative tasks. These are independent programs with substantially different purposes, but they are often used in conjunction. In this talk, I describe a flaw in their interaction, and then present our solution called public-key sudo.

    Public-key sudo is an extension to the sudo authentication mechanism which allows for public key authentication using the SSH public key framework. I describe our implementation of a generic SSH authentication module and the sudo modifications required to use this module.

    Integrated Enterprise Security Management

    Security policies are a key component in protecting enterprise networks. But, while there are many diverse defensive options available, current models and mechanisms for mechanically-enforced security policies are limited to traditional admission-based access control. Defensive capabilities include among others logging, firewalls, honeypots, rollback/recovery, and intrusion detection systems, while policy enforcement is essentially limited to one-off access control. Furthermore, access-control mechanisms operate independently on each service, which can (and often does) lead to inconsistent or incorrect application of the intended system-wide policy. We propose a new scheme for global security policies. Every policy decision is made with near-global knowledge, and re-evaluated as global knowledge changes. Using a variety of actuators, we make the full array of defensive capabilities available to the global policy. Our goal is a coherent, enterprise-wide response to any network threat.
