Why we use this services?

Below are the lists of services and feature that the network includes in Moritz Law Firm.

Dynamic Host Configuration Protocol (DHCP)
To enable load balancing and wireless users on the network, DHCP will be
installed on each router. DHCP will assign IP addresses required by hosts inside
the LAN dynamically so that balance traffic for each IP address can be managed.
At least one network administrator on each LAN will have to manage and monitor the
information stored for each IP addresses assigned to a host.

Domain Name System (DNS)
Moritz Law Firm has currently managed a website from its web server in
Sydney.
However the web server will no longer served for static purposes only but
also as the interface for the new system. The new system will make the use of FTP
service to enable file upload and sharing that will be accesses through a browser as
an interface.

Apache - SSL
Apache is installed to serve the web site. It comes along with an SSL features that will enable the creation of a secure and reliable web system (The Apache HTTP Server
Project, 2009). It will then lead the website to make the use of HTTPS to secure the
web pages and its content from unauthorized users. Here users will need to gain a
certificate authority before actually logged in to the system. It will assist the network monitoring at the same time.

File Transfer Protocol (FTP)
To enable data sharing between the two branches, all files will need to be uploaded to the server. There are times when staff in Melbourne will be required to upload a file to the Sydney server directly or vice versa.
To do so, an FTP server is installed. Anonymous access has been disabled for security purposes so that only authorised users can access and use the server.

SSH
Due to the business atmosphere, SSH is installed in the server for data encryption
especially when high level of confidentiality document is about to accessed. This
service will allow users with higher level of authority to access important document.

Simple Network Management Protocol (SNMP)
SNMP is installed to allow monitoring of the entire network attached devices in the
network that may help the administrator to get through problems quickly (Zend
Technologies Ltd., 2009). SNMP is installed in the server and each workstation will
get act as an SNMP agent so that the network administrator can monitor each devices
remotely.

MRTG
To ensure that network traffic is keep in a reasonable load, a network monitoring
traffic is installed. MRTG is chosen since the network employs SNMP which make it
easier to use MRTG. Using MRTG, the network administrator may get a graph showing the traffic load for each five minutes. The OID is set to five minutes to allow time to time monitoring.

SQUID
The main purpose to install SQUID proxy server is to do traffic filtering which
include some websites access blocking so that only certain websites is allowed to be
access by staff. It is done to keep the load traffic low and in an appropriate use.
Another reason to install SQUID is to do web caching since only few defined
websites is accessible through the network which means caching will be extremely
helpful to speed up the network speed.
