How can I configure the firewall on my computer to use a Peer2Peer service?

July 28th, 2011

I want to use something like LimeWire, Frostwire, Ares, etc, but nothing works because of the firewall. I used to be able to connect to LimeWire, until I updated it with their newer version. Now I can’t use any P2P service.
I add the PORT and the number for the specific P2P and it still won’t connect.

What does a Firewall Vulnerability Assessment consist of?

July 26th, 2011

I am currently creating an RFQ (request for quotation) for a firewall vulnerability assessment. What are the main components/procedures/functions that are usually included?

Note: I am preparing a report to bring in consultants to conduct the assessment, not buying the software to do it.

How a Personal Firewall Helps to Protect Your Home Computer From Hackers

How a Personal Firewall Helps to Protect Your Home Computer From Hackers

There are two types of firewall available to the home computer user. A hardware firewall is a device which sits between your computer and the internet. At home for example it could reside on a broadband router which is used to share your internet connection with a number of computers. One of the advantages of a hardware firewall is that it can be used to protect more than one computer at a time. For this reason hardware firewalls are deployed in corporate networks. For home users who own just one computer a personal firewall is more commonly used and more cost effective.

A personal firewall is a software application that monitors and can block the flow of data between the internet and your computer. The firewall is a key part of your computer security set up. It prevents hackers from gaining access to your computer using an internet connection.

Hackers gain access to your computer through open ports that are used by your computer to communicate with the internet. The most basic firewall programs, like Windows XP’s firewall, monitor and can block “inbound” traffic by closing these ports. If theses ports are closed a hacker cannot access your computer directly via the internet.

More advanced firewall programs like products from ZoneLabs or Symantec also monitor and can block “outbound” traffic. This extra level of security is important and is worth investing in. For example, if malicious software like a Trojan Virus or spyware were installed on your computer without your knowledge the firewall would alert the user when it tried to connect to the internet and prevent it communicating with its host.

A firewall usually works at two basic levels. Firstly, packets of data are analysed based upon IP address and content to see whether they comply with a set of rules which a user can input to. The second level the data is analysed is at the application level. The firewall determines whether an application can send and/or receive data and the port which it should be communicating through.

The firewall “learns” through continuous interaction with the user. It seeks user approval from programs when they first come in to contact with the firewall. Most firewalls also allow the user to allow or block applications through a stored list of program which can be accessed through the firewall’s user interface.

There are a number of sites which will help test your firewall’s effectiveness. A number of these sites are run by security software vendors so it is recommended you test using an independently run site to double-check any results. One of the best independent test sites is run by The Gibson Research Corporation. They offer a free test called “Shield Up!” which can be found at their website – http://www.grc.com. The test checks a number of well-know and vulnerable ports on your computer and then provides some useful additional information to help improve your security while online.

It is important to remember that the firewall is only part of your computer security and does not negate the need for a good anti virus solution, a spyware removal tool and a degree of caution / common on sense on the type of websites a user visits. For example, the firewall will not scan for viruses or remove them from your computer.

Richard Rogers is a owner of a number of computer related sites. One of his sites offers Free Computer Help for Windows XP Users and has just launched his new Registry Cleaner Blog.

Sunbelt Personal Firewall

November 9th, 2010

Sunbelt Personal Firewall

Sunbelt’s Personal Firewall is our top choice again this year as the best stand-alone personal firewall. It’s simple but powerful.

Make no mistake, this is a serious firewall software suitable for the most demanding uses. But Sunbelt has made it accessible even for novice users.

Sunbelt keeps up their record of delivering strong, easy to use software with this release of their Personal Firewall.

In our many test installations, we didn’t encounter any snags, although it’s important to note the Personal Firewall isn’t yet compatible with 64-bit versions of Windows.

The user interface is well set up to for both novices and advanced users. You can either set-it-and-forget-it or fully customize it to suit your needs.

Resource usage was excellent. For such a strong and fully active bi-directional firewall, we found little to no effect on system load, even under the high volume network attacks we threw at our test PCs in our labs.

It should be noted that while this is and excellent software firewall, a firewall alone doesn’t mean your PC is protected. For Sunbelt, that comes in the VIPRE Antivirus Premium firewall combo.

By upgrading to VIPRE Antivirus Premium, your PC has protection against all types of viruses, worms, trojans, and other attacks.

Alone, Sunbelt Personal Firewall is powerful in its own right, but VIPRE Antivirus Premium offers a high-performance, high-value antivirus firewall software to help protect your PC online.
