Secure Session Layer Services
draft-hares-i2nsf-ssls-02

Abstract

Each I2NSF agent and I2NSF client needs to provide application level support for management traffic during periods of DDoS and network security attacks to deal with congestion (burst and/or continuous), high error rates and packet loss due to the attacks, and the inability to utilize a transport protocol (E.g. TCP) due to a specific protocol attack. This application level support needs to be able to select the key management system and provide "chunking" of data (in order to fit in reduced effective MTUs), compression of data (in order to fit into reduced bandwidth), small security envelope )in order to maximize room for management payload), and fragmentation and reassembly at the application layer for those protocols which do not support fragmentation/reassembly (E.g. UDP or SMS). These Secure Session Layer services may only be deployed on a the few management ports which need to be protected during DDoS attacks or network security attacks, and turned on/off based on need. The application and the network instrumentation need to cooperate to determine if this service needs to be turned on or off. This draft specifies a security session layer services(SSLs) which provide these features in terms of APIs (North-Bound and South-bound), and the component features (interface to key management systems, data compression, chunking of data, secure session envelope (SSE) to send data, and fragmentation and reassembly, and ability to detect existence of attack).
