Securing Dedicated Server using Firewall

A firewall is software (or) Hardware used to control the security of a private network. Firewalls block unauthorized access to private networks and these are often used to control unauthorized (or) unlawful web users from accessing private networks connected to the Internet. The hardware firewall is a managed platform that connects dedicated serversto a dedicated port on a firewall shared by multiple clients. Each client gets its own configuration per port and there is complete isolation between users.


A basic firewall would at least have the effect of stopping someone who randomly scans servers and cross yours to test for vulnerabilities. The simplest set of rules in place should effectively deter any light or casual intruders. However, depending on the level and determination of the unwanted guest, a more advanced configuration may be required.


Firewalls are essentially software that blocks unwanted access to your server while allowing it to function normally. This is something that almost everyone who runs a site needs, and there are a number of benefits mentioned below.


  • Block access: Blocking your server does not mean that no one will be able to access it. In fact, you can configure your firewall to grant access only to a few specific users identified by their IP addresses.

  • Reduce the risk of attacks on sites: Most servers store sensitive information data such as documents, e-mail addresses and passwords. Of course, many of these data are encrypted, but you still do not want leaks on your watch.

  • Easy to configure firewalls: Many hosting providers and content management systems include configuration options for specific types of firewalls.


When using a Windows or Linux server, the built-in firewall allows you to select basic settings to prevent unknown users from connecting using the Remote Desktop Protocol (RDP), which is equivalent to Linux, but to explicitly allow connections to these. services from approved IP addresses. So if your colleagues, the development team or just you have to access the server. Then a simple firewall filter will be there to save the day. Depending on your particular system requirements, things can be a bit advanced when it comes to configuring these rules.


For more advanced server configuration and firewall configuration, your best choice will be to use a Cisco PIX. The PIX firewall is like one of the knives of the Swiss army on the Internet. It offers a robust application of application and user policies, protection against attacks and secure connectivity services in cost-effective and easy-to-deploy solutions.

More than ever before for malicious groups on the Internet stealing data or disrupting e-commerce has become a very big business.
