This article proposed a secure design for network
and system in windows environment using the
latest technology. The security of networks always
faces new potential threats as hackers and viruses
advance. The design shows how the network can
be more secure by encrypting the sending data
using internet protocol security between user and
server. The purpose of network security is to
provide availability, integrity, and confidentiality.
Thus, the main objective of VPN is to prevent
outsiders (hackers) from interfering with messages
sent among hosts in the network, and to protect the
privacy and integrity of messages going through
untrusted networks. The active directory manages
all network resources such as servers, shared files,
and printers, through authorization access
resources. In addition to Active Directory, the
main protection's servers such as WRMS, and
WSUS, and Symantec make the internal network
'LAN' protected and secured against threats and
viruses.
After applying our proposed design and these
concepts to an enterprise with worldwide branches,
they proved efficient and highly reliable as
network security mechanism. Therefore, all the
mechanisms thoroughly discussed in this project
proved to work well together and provide the
needed security in any professional setting.
