Configuring Web Session Time-Outs

When a user is logged on to the Firebox SSL VPN Gateway and using a Web browser to connect to Web sites in the secure network, cookies are set to determine if a user’s Web session is still active on the Fire- box SSL VPN Gateway. If the Firebox SSL VPN Gateway cookie expires and logon page authentication is enabled, the end user is prompted to enter authentication credentials to resume the Web session. This provides a measure of security for limiting the amount of time network attacks could occur during an unattended Web session.

To enable Web session time-outs

1Click the Global Cluster Policies tab.

2Under Access options, type the number of minutes in Web session time-out.

To disable Web session time-outs, type 0 in the text box.

Disabling Desktop Sharing

The Secure Access Client includes a desktop sharing feature. A user can right-click the Secure Access Cli- ent icon in the Windows notification area and select Share Desktop. Selecting this option displays a list of all other users who are logged on to the Firebox SSL VPN Gateway from a Secure Access Client.

In some organizations, this feature may cause privacy concerns because it allows any user who logged on through the Secure Access Client to view a list of all other users who are currently logged on.

If you want to prevent a specific group of users from viewing the list of online users, you can disable the desktop sharing feature for an Firebox SSL VPN Gateway user group.

Disabling desktop sharing for a user group causes the following to occur:

When a member of the user group right-clicks the Secure Access Client icon in the Windows notification area, the Share Desktop option is not on the menu. Users in this group cannot display a list of the other online users from the Secure Access Client icon (or use the desktop sharing feature).

Members of the user group do not appear in the online lists of other users for whom desktop sharing is enabled.

To disable desktop sharing

1Click the Access Policy Manager tab.

2In the left pane, right-click a group and click Properties.

3On the General tab, under Application options, select Disable desktop sharing.

4Click OK.

Setting Application Options

Application policies limit the network access further by assigning individual network resources to spe- cific applications. Application policies define the network path and endpoint policies for a specific appli- cation. When an application policy is created and then added to a user group, the application can use only the specified network path and endpoint policy. This does not prevent other applications from using these resources. To prevent applications from using these network resources, you can deny access to the network.

To deny applications without policies

1On the Access Policy Manager tab, right-click a user group and click Properties.

SSL VPN specifications

WatchGuard Technologies offers a robust SSL VPN solution designed for secure remote access to corporate networks. As businesses increasingly rely on a remote workforce, the need for secure and reliable connectivity has never been more critical. WatchGuard's SSL VPN features advanced security technologies that ensure data integrity and confidentiality while enabling seamless access to applications and resources.

One of the standout features of WatchGuard's SSL VPN is its user-friendly interface. The solution is designed to simplify the user experience, enabling employees to connect to the VPN with minimal complexity. With a straightforward setup process, users can quickly establish secure connections from various devices, including laptops, smartphones, and tablets. This flexibility supports a diverse workforce, allowing employees to work from different locations without compromising security.

In addition to its ease of use, WatchGuard's SSL VPN is built on robust security technologies. It employs end-to-end encryption to safeguard data in transit, ensuring that only authorized users can access sensitive information. By utilizing SSL (Secure Sockets Layer) protocols, the VPN creates a secure tunnel between the user’s device and the corporate network, protecting against potential threats such as eavesdropping or man-in-the-middle attacks.

Moreover, WatchGuard Technologies includes multiple authentication options, adding another layer of security. The solution supports multi-factor authentication (MFA), requiring users to provide additional verification beyond just a password. This could involve mobile device verification or biometric authentication, significantly reducing the risk of unauthorized access.

Another key characteristic of WatchGuard’s SSL VPN is its integration with other WatchGuard security solutions. Businesses can benefit from a comprehensive security posture by leveraging firewalls and intrusion prevention systems along with the SSL VPN. This holistic approach ensures that remote connections are continually monitored and secured against evolving cyber threats.

Scalability is also a crucial aspect of WatchGuard's SSL VPN, accommodating growing organizations with changing needs. The solution can easily scale to support an increasing number of remote users without compromising performance. With robust performance metrics, businesses can ensure that even during peak usage times, the VPN remains responsive and reliable.

In summary, WatchGuard Technologies' SSL VPN solution combines ease of use, robust security, flexible authentication, and scalability. These features make it an ideal choice for organizations seeking to provide secure remote access to their employees while maintaining a strong defense against cyber threats. With WatchGuard, businesses can confidently navigate the challenges of a digital landscape, ensuring their network remains secure as they embrace remote work.
