Mobile code technologies such as Java, JavaScript, and ActiveX
generally limit all programs to a single restrictive security policy.
However, software-based protection can allow for more extensible
security models, with potentially significant performance improvements
over traditional hardware-based solutions. An extensible security
system should be able to protect subsystems and implement policies
that are created after the initial system is shipped. We describe and
analyze three implementation strategies for interposing such security
policies in software-based security systems. Implementations exist
for all three strategies: several vendors have adapted capabilities to
Java, Netscape and Microsoft have extensions to Java's stack
introspection, and we built a name space management system as an
add-on to Microsoft Internet Explorer. Theoretically, all these
systems are equivalently secure, but many practical issues and
implementation details favor some aspects of each system.
