Resilient overlay network for self-protection of information system networks

Loïc Baud,Patrick Bellot,Michel Riguidel

We have developed a scalable resilient overlay network for self-protection of information system networks,named ROSA. ROSA permanently reconfigures itself to improve its connectivity in order to circumvent failures or weakness in the network. It collects the values delivered by software sensors distributed over the CIS. Such sensors return values obtained by SNMP and system queries. ROSA computes Security Assurance (SA) values for every entity of the CIS. SA values,that we have developed,aim to represent the health of the entities. When the SA value of an entity decreases below a given value,ROSA applies some Security Policy rules. These rules are mainly reconfiguration actions intended to protect the systems,services and hardware under attack or under failure.

  • The ROSA White Paper available here (3.5 MB) describes a large part of this work.
  • A movie available here shows a real size implementation using the ROSA network of Loïc Baud and the security metrics of Pham Viet Tan Nuguen. It has been run over the department network for weeks ensuring proper routing even in case of failure. The state of the network is shown in a Security Cockpit Console.

The ROSA overlay network is planned to be used in the Distributed middleware for Wireless Sensor Networks project.
