abstract = {We present a formal model of network protocols and their application to modeling firewall policies. The formalization is based on the \emph{Unified Policy Framework} (UPF). The formalization was originally developed with for generating test cases for testing the security configuration actual firewall and router (middle-boxes) using HOL-TestGen. Our work focuses on modeling application level protocols on top of tcp/ip.},

@Article{ brucker.ea:formal-fw-testing:2014,
abstract = {Firewalls are an important means to secure
critical ICT infrastructures. As configurable
off-the-shelf prod\-ucts, the effectiveness of a
firewall crucially depends on both the correctness
of the implementation itself as well as the
correct configuration. While testing the
implementation can be done once by the
manufacturer, the configuration needs to be tested
for each application individually. This is
particularly challenging as the configuration,
implementing a firewall policy, is inherently
complex, hard to understand, administrated by
different stakeholders and thus difficult to
validate. This paper presents a formal model of
both stateless and stateful firewalls (packet
filters), including NAT, to which a
specification-based conformance test case
gen\-eration approach is applied. Furthermore, a
verified optimisation technique for this approach
is presented: starting from a formal model for
stateless firewalls, a collection of
semantics-preserving policy transformation rules
and an algorithm that optimizes the specification
with respect of the number of test cases required
for path coverage of the model are derived. We
extend an existing approach that integrates
verification and testing, that is, tests and
proofs to support conformance testing of network
policies. The presented approach is supported by a
test framework that allows to test actual
firewalls using the test cases generated on the
basis of the formal model. Finally, a report on
several larger case studies is presented.},
