Published: December 16, 2009

Applies To: Forefront Client Security

The Windows Firewall check identifies whether the Windows Firewall is enabled (on the scanned computer) for all active network connections. The check also identifies port exceptions, service exceptions, and application exceptions..

Windows Firewall is software that runs on your computer and provides protection against network attacks from the Internet or other computers on the network

Windows Firewall is included in Windows XP SP2, Windows Server 2003 SP1, and Windows Vista. Internet Connection Firewall (ICF) is included in Windows XP prior to SP2 and Windows Server 2003 prior to SP1. This check pertains to Windows Firewall and not to ICF.

Resolutions for potentially unacceptable scores

It is recommended that you enable Windows Firewall for each network connection on a computer. You can change firewall settings through: Control Panel WindowsFirewall or by using Group Policy. For more information about Windows Firewall, see How to turn of or turn off the firewall in Windows XP (http://go.microsoft.com/fwlink/?LinkId=19699) and Managing Windows XP Service Pack 2 Features Using Group Policy: Windows Firewall (http://go.microsoft.com/fwlink/?LinkId=95063)

Cannot start a download in IDM. An error occurs on download start.

How to configure Windows Firewall to work with Internet Download Manager (IDM)

When you installed Windows XP Service Pack 2. you have also installed Windows inbuilt FireWall. Typically its default settings correspond very well to the Internet Download Manager. Most probably no problems will occur at all. However, should you run up against problems, please follow these steps:
1. Open the Windows Firewall settings dialog window: “Start > Settings > Control Panel > Window Firewall” or “Start > Settings > Control Panel > Network and Internet connection > Window Firewall”.

2. On the “General” tab make sure the “Do not allow exceptions option” is not selected.

3. Switch to the “Exceptions” tab with the list of applications that are allowed to access to the Internet. You need to allow access to Internet for “Internet Download Manager” application. To do so, mark the check box related to the IDM application in the list of programs and services: “Internet Download Manager”.

If this application is not listed in the list of exceptions, you need to add it manually. This can be done using the “Add Program” button. See below.

4. A new dialog window opens providing a list of programs that can be added to the previously seen Windows FireWall list of exceptions. Select the IDM application from the list, and confirm adding it to the Windows Firewall list of exceptions by pressing on “OK” button. In case you are not able to see the IDM application in the program list, you have to add them manually. Click the “Browse” button, and find the “IDMan.exe” file (by default “C:\Program Files\Internet Download Manager\IDMan.exe” ).

After these actions IDM will start downloading normally.

Top 10 Open Source WAF (Web Application Firewalls) for Web App Security #web #application


Top 10 Open Source WAF (Web Application Firewalls) for Web App Security

Web application firewalls provide security at the application layer. Essentially, WAF provides all your web applications a secure solution which ensures the data and web applications are safe.

A web application firewall applies a set of rules to HTTP conversation to identify and restrict the attacks of cross site scripting, SQL injections etc. You can also get web application framework and web based commercial tools, for providing security to web applications. Web Application Firewalls allows you to customize the rules by identifying and blocking malicious content. Some of the most popular and widely used open source web application firewalls for web application security (including various server operating systems like Unix, Linux, Windows and Mac OSX) are

    ModSecurity is one of the oldest and widely used open source web application firewall which can detect application level threats on internet, and provides security against a range of security issues to web applications. It provides non viral open sources license and it can be integrated to Apache programs. Recently, ModSecurity released the version 2.6.0 which provides features for safe browsing API integration, sensitive data tracking and data modification features. This is available on all major operating systems including Unix, Windows and Linux. If you are looking for a windows WAF this may be a tool worth try before buying an expensive enterprise software.

    AQTRONIX WebKnight is an open source application firewall designed specifically for web servers and IIS, and it is licensed through the GNU General Public License. It provides the features of buffer overflow, directory traversal, encoding and SQL injection to identify / restrict the attacks.

    ESAPI WAF is developed by Aspect Security and it is designed to provide protection at the application layer instead of network layer. It is a Java based WAF which provides complete security from online attacks. Some of the unique features of the solution include outbound filtering features which reduce information leakage. It is configuration driven and not code based, and it enables easy installation by just adding configuration details in the text file.

    WebCastellum is a Java based web application firewall which can protect application against cross site scripting, SQL injections, command injections, parameter manipulation, and it can be integrated easily to a java based application. It is based on new technology and it can use existing code to provide protection.

    Binarysec is web application software firewall, and it protects applications against illegitimate HTTP and blocks suspicious requests as well. It provides protection against cross site scripting, commend injections, parameter tampering, buffer overflow, directory traversal, SQL injection and attack obstruction. It takes not more than 10 minutes to install the software, and its user interface can manage Apache and other web servers and many sites on one machine.

  2. Art of defense is a San Francisco based web application security provider which started a project on open source OpenWAF in February 2011. It s also the first company to provide distributed web application firewall for Apache servers.

    Qualys created cloud based open source web application firewall – Ironbee which examines the HTTP instead of the traditional IP packets to evaluate a data. It can even track attacks on cross site scripting code. Ironbee is published through Apache License version 2 and it provides no copyright assignment. It has modular structure and is quite easy to use.

    ZION security offers an open source web application firewall similar to ModSecurity, and is called Profense. The web application firewall provided by Zion is essentially a Layer-7 firewall (which is also called proxy firewall ) and it inspects the traffic to block content.

    Smoothwall provides strong web security tools to manage emails. The open source web filtering engine of Smoothwall is called DansGuardian. It has flexible user rules and a fully integrated component for web filtering and security. What s more, it provides authenticated network access and traffic blocking. Smoothwall free firewall has security hardened Linux GNU OS too.

    Internet based protection is also provided by companies which provide security at the network layer with features such as packet filter. Besides, there are some other types of firewalls which are designed to ensure security of the database. Therefore, the criteria for selecting an open source WAF should be the types of vulnerabilities the WAF can prevent and the exact requirements that your company is having. This list of open source web application firewalls would hence assist you in determining the apt WAF for Webapp security.

    Hope you found this list useful! What is your experience with WAF? Please don’t forget to share with me in comments.

    Next-Generation Firewall #strongest #firewall


    Next-Generation Firewall

    Historically, next-generation firewall (NGFW) appliances were designed to deliver a very specific set of security services – firewall, intrusion prevention, and application control. Since being originally defined, the security threats and the technology available to combat those threats have significantly evolved, creating a demand for additional network security services. As a result, other techniques and services have to be included in basic NGFW appliances such as SSL inspection, website filtering, QOS, antivirus inspection, and even sandboxing. While these additional services provide value to end users, it also confuses many people, making them wonder about the difference between an NGFW and UTM appliance .

    Today, companies should not be searching for an NGFW or a UTM appliance, they should be searching for the right network security appliance that meets the security, deployment, and management requirements of their unique organization.

    WatchGuard’s Solutions

    Our unique approach to network security focuses on bringing best-in-class, enterprise-grade security to any organization, regardless of size or technical expertise. Ideal for SMB, midsize, and distributed enterprise organizations, our network security appliances are designed from the ground up to focus on ease of deployment, use, and ongoing management, in addition to providing the strongest security possible.

    Not only does WatchGuard offer the greatest collection of network security services on a single platform, we do so in a way that has proven to be the most agile, able to adapt to new and evolving threat vectors faster than any other solution on the market.

    We are a security company and we want the best protection for every customer, every time. As such, we strongly recommend customers adopt a full security suite. When running WatchGuard’s Total Security Suite, our Firebox network security appliances offer the strongest security against network threats. Every Firebox can be purchased as a stand-alone NGFW appliance; however, as a security company we never recommend the deployment of an NGFW without other security mechanisms in place. The best approach to security is a layered approach.

    Regardless of which Firebox appliance you choose, WatchGuard offers the broadest range of enterprise-grade network security and visibility services with an emphasis on ease of deployment and centralized management. We make it easy for you to build the right security solution for every business.

    Whether you have a single location, a small chain of restaurants, or thousands of retail locations around the world, WatchGuard has the right appliance for your environment. And with Total Security available on every appliance, security is never a compromise.
