Yes it is necessary , it block all unauthorized access to your pc also it blocks some non-trusted software to access your internet.
U need firewall anyway.
A firewall works as a shield between your PC and cyber space. When you are connected to the Internet, you are constantly sending and receiving information in small units called packets. Firewall filters these packets to see if they meet certain criteria set by a series of rules, and thereafter blocks or allows the data. This way, hackers cannot get inside and steal information such as bank account numbers and passwords from you. The firewall included in Windows XP, only monitor incoming traffic by default. But a good firewall will monitor traffic in both directions.
Yes firewall is necessary
A firewall is a network security system, either hardware- or software-based, that uses rules to control incoming and outgoing network traffic. A firewall acts as a barrier between a trusted network and and an untrusted network. So if you want to safe your website or application then you must use firewall network.

Here are some points for you -
It stops the un-trusted traffic. You can define set of rules in your way so you can stop the attacks or hack attempts on your server.
If your servers's bandwidth is utilized by the un-authorized IP addresses then you can block such traffic. You can block the particular port in the firewall so no one can access it.
You have option to allow IP or deny IP in firewall that is either allow those IP addresses to access your network or particular port or disallow them to access them some features on the server. The blocks will be automatically removed after some time as per the rule set in firewall.
Firewall is the best option to secure your server.
