INFORMATION SYSTEMS SECURITY - MICHAEL ADJEDJ J...

The management of services and operations in today's organizations are - coming increasingly
dependent on their enterprise local area network (enterprise LAN). An enterprise LAN consists
of a set of network zones (logical group of networkelements)correspondingto di?erent
departments orsections connected through various interface switches (typically  Layer-3
switches). The network service accesses between these zones and also with the external network
(e. g.   Internet) are governed by a global network security policy of the organization. This
global policy is de?ned as a collection of service access rules across various network zones
where the services referred network applications conforming to TCP IP protocol. For example 
some of the known network services aressh  t- net etc. In reality  the security policy may be
incompletely speci?ed  which explicitly states the permit and deny access rules between speci?c
network zones keeping remaining service access paths as unspeci?ed. The global security policy
is realized in the network by con?guring the n- work interfaces with appropriate sets of access
control rules (ACLs). One of the major challenges in network security management is ensuring
the conformation of the distributed security implementations with the global security policy.
