Virtual Secure Network

A Virtual Secure Network (VSN) is a novel network service, providing safe and secure web content to remote users. The underlying principles can be used to offer security protections (like firewalls, Antivirus scanners, IDSs and IPSs) as a service from the cloud.

A corporate network typically has IDSes, firewalls, and malware scanners to protect the machines on the network from attack. However, employees may use devices with sensitive data in remote locations. This leaves the company with a choice: either have the remote users VPN their traffic back to the corporate network for protection; or let its employees connect directly to the (insecure) Internet. The former choice can be very slow for users as well as costly for the organization, while the latter increases the security risk. In this work, we address this problem by designing, prototyping and evaluating a novel network service called Virtual Secure Network (VSN). A VSN server provides remote clients the security benefit of being behind a corporate network, while providing Internet performance more typical of an (insecure) direct connection. The VSN server pushes hashes of secure content to clients. Clients that want to obtain content on the hashlist do so directly over the Internet but have the same security assurances as though they were in the corporate network. Our preliminary trace simulation results show that our VSN service can significantly reduce both user-perceived delay and deployment cost. The VSN service concept can also be extended to cloud-based security services - providing the security offerings as a subscription service.

JumpBox Trac Information

This Trac JumpBox has everything you need to get working right away. Your SVN repository is stored on this machine as well. We have installed the Web Admin and Account Manager Plugins to simplify administration for most users.

Your SVN repository can be accessed here:


To Add Users you will first need to login by clicking the red login link on the top right hand side of this page. You will login in as the user admin and the password you used when configuring your JumpBox. Once you are logged in as the administrator new users can be added by clicking on the Trac Admin link (it will appear on the top right once you log in) then the Users link. These users will have access to both Trac and the Subversion repository. Many other settings can be changed through the Trac Admin link.

Welcome to Trac 0.12.3

Trac is a minimalistic approach to web-based management of software projects. Its goal is to simplify effective tracking and handling of software issues, enhancements and overall progress.

All aspects of Trac have been designed with the single goal to help developers write great software while staying out of the way and imposing as little as possible on a team's established process and culture.

As all Wiki pages, this page is editable, this means that you can modify the contents of this page simply by using your web-browser. Simply click on the "Edit this page" link at the bottom of the page. WikiFormatting will give you a detailed description of available Wiki formatting commands.

"trac-admin yourenvdir initenv" created a new Trac environment, containing a default set of wiki pages and some sample data. This newly created environment also contains documentation to help you get started with your project.

You can use trac-admin to configure Trac to better fit your project, especially in regard to components, versions and milestones.

TracGuide is a good place to start.
