Proposals for programmable network infras-
tructures, such as active networks and open sig-
naling, provide programmers with access to
network resources and data structures. The moti-
vation for providing these interfaces is accelerated
introduction of new services, but exposure of the
interfaces introduces many new security risks. The
risks can be reduced or eliminated via appropri-
ate restrictions on the exported interfaces. In this
article we describe some of the security issues
raised by active networks. We then describe our
secure active network environment architecture.
SANE was designed as a security infrastructure
for active networks, and was implemented in the
SwitchWare architecture. SANE restricts the
