While using networks that may be in any form more
and more problems related to securityrises within the network as
well as outside the network. To resolve the security problems
network security is the science that facilitatesto safeguard the
resources and the quality of the network and data. At different
workstations filters and firewalls are used in protecting the
resources. But while the data is in transmission security services
are needed to protect. These services are to be altered frequently to
prevent from attacks. In developing such system, this work uses
linear congruential pseudorandom number with multiple genetic
algorithms. In small business applications these types of hybrid
systems can be used to prevent from hackers.
