Unmanaged websites surfing is killing your productivity. And your computer and network is open to attack when visiting harmful sites.
So it is important to block unwanted websites in your network. Blocking of websites can be done in many ways. These include using free software and windows settings. There are even many add-ons for browsers like Firefox which let you check and restrict websites.

This tutorial will guide you to filter and block websites access in 4 ways.

1. manually editing the "host" file.

In "Local Disk (C:) > WINDOWS > system32> drivers > etc", you will find a file named "host". The Hosts file contains the mappings of IP addresses to host names. This file is loaded into memory (cache) at startup, then Windows checks the Hosts file before it queries any DNS servers, which enables it to override addresses in the DNS. This prevents access to the listed sites by redirecting any connection attempts back to the local (your) machine.
You may use "notepad.exe" to edit this Hosts file.
Example - the following entry 127.0.0.1 ad.doubleclick.net blocks all files supplied by that DoubleClick Server to the web page you are viewing.

2. Opendns

OpenDNS offers DNS resolution for consumers and businesses as an alternative to using their Internet service provider's DNS servers. By collecting a list of malicious sites, OpenDNS blocks access to these sites when a user tries to access them through their service.
OpenDNS enables you to block websites by 50+ categories. OpenDNS also provides whitelist and blacklist features to enable you to create exception cases ("always allow" and "always block") to complement category-based filtering.

To use OpenDNS service, you need to change your DNS server settings manually.

3. Router, Firewall or UTM

If you have a powerful router or UTM device, you also can setup web filtering on it.

4. Internet filtering products

You also can use internet filtering products to do web filtering. An internet filtering product can be deployed in your network, and it enables you to monitor, filter and block internet activities of all computers from a mirroring port.
More than web filtering, internet filtering product can also block file downloading, block p2p traffic and block messenger.

For internet filtering software, you can try "WFilter Enterprise", http://www.imfirewall.us

Instant Messaging can be a benefit to business when used properly, but IM is often abused by employees and poses significant liability and security risks.

The free consumer IM client programs in widest use, such as AIM, ICQ, Yahoo and MSN Messenger, pose many security concerns. More than text-based chat, IM programs also include peer to peer file transfer capabilities, which can pose security risks in two ways. Internal users can send documents that may be confidential out of your network, circumventing your network's perimeter defenses against file sharing programs or e-mail attachments. On the other hand, external users can send files that might contain viruses or malicious code to users on the internal network. In addition, a liability risk arises if employees use the file transfer feature to share copyrighted music, movie or software files in violation of the law.

To make your business efficient, it is necessary for you to monitor, filter and block instant messaging in your network.

You may want to apply an internet messenger usage policy like this:

1. Only authrozied users can use certain IM tools.

2. File transfer via messengers shall be blocked.

3. Only work-related IM accounts can be used.

As most firewall programs do not support that kind of feature, you need an internet monitoring and filtering program like "WFilter Enterprise". "WFilter Enteprise" enables you to monitor, manage and block internet access of all computers on a mirroring port. For internet messaging blocking, WFilter supports:

1. Blocking certain messenger protocols.

2. Blocking file transfer via messengers.

3. Blocking certain messenger account using black/white list.

  Unmanaged internet downloading can consume most of your bandwidth, In practice, many, often most, of the files shared on peer-to-peer networks are copies of copyrighted popular music and movies. 

  So, it is important for corporations to manage, control and block p2p traffic and block unwanted file downloading.

  Files can be downloaded via various ways as described below:

  1. Downloading from HTTP/FTP websites.

  2. Downloading from p2p networks.

  3. Downloading from instant messenger buddies.

  For security purpose, downloading from p2p networks shall be completely forbidden in company networks. And only HTTP/FTP downloading from trusted websites can be allowed.

  Instant messenger file transfer makes it convenient to share files with our friends. It is fast and secure. However, because IM is so popular, virus writers can use it to spread malicious programs. These viruses are spread, in most cases, when a person clicks a link or opens an infected file that was sent in an instant message that appeared to come from a friend. Therefore, messenger file transfer also put your network in danger.

  "WFilter Enterprise"  makes it simple to manage file transfers between local network and the internet. Using WFilter, you may:

  1. Limit file downloading size.
