 The Brooklyn Circus owner does not
want confidential files stolen. For this
reason, the network administrator has
configured essential security tools on
Windows Server 2008 which maintains
the integrity of the businesses data.
 One of the major concerns are the
constant changes to files and financial
information currently housed on
Windows Server 2008 has been a major
testament to its’ success and growth.

 The prime importance of securing
Brooklyn Circus’ network is to
prevent loss, through misuse of
data.
 The main threats which may erupt if
network security is at risk are
 Breaches of confidentiality
 Data corruption
 Data manipulation

Network Access Protection
(NAP)

 A set of security features which
monitors and manages the
Windows Server 2008 and its’
clients to ensure the same level
of security is maintained on all
computers.
 If a client computer does not
have the current security
updates, NAP will either limit
access to the network or
automatically update the clients’
computer.

Snort Intrusion Detection Systems
(SIDS)
Security countermeasure solution which enhances
network security of the network infrastructure.
 Implemented at the information infrastructure security level.
 Serves as the next line of defense after the firewall.
 Monitor network traffic of all the domains by pinpointing
intruder attacks in real time mode.
 The firewall blocks access points within the network; however,
they are unable to decipher between malicious activities of
hackers.

 The firewall will block the specified address.
