How would you Build an Open Source Secure Web Gateway? What are some of the challenges you might face?
Build an Open Source Secure Web Gateway
Open Source Secure Web Gateway is a project for building an Open Source Secure Web Gateway. The project’s goal is to provide a solution for small and medium enterprises to protect their web gateway environment. It includes Open Source Web Gateway, an Open Source Mail Server with Anti-spam and Anti-virus solutions, and Open Source VPN Server.
The project aims to provide a complete set of solutions that are reliable, secure, and free. Open Source Secure Web Gateway is a web gateway based on Linux distribution. Also, it consists of several open sources of software such as Apache2, Squid3, Openswan, Fail2ban, and ClamAV.
It uses Postfix as a mail server and OpenVPN as a VPN server to offer a complete set of security solutions for SMEs. Open Source Secure Web Gateway provides comprehensive protection for SMEs at three different levels.
Secure Web Gateway Architecture
Open Source Secure Web Gateway Architecture is based on the Linux distribution. It consists of several open sources of software such as Apache, a lightweight web server, and an HTTP proxy server. A squid proxy server is used as a reverse proxy for HTTP and HTTPS traffic.
This includes OpenSwan and IPsec virtual private network (VPN) server. Fail2ban, a daemon to monitor and ban IP addresses will help show malicious activity. As well as the ClamAV, an Open Source antivirus engine.
Open Source is a Linux distribution based on Debian stable. Moreover, it aims to provide a complete set of security solutions for SMEs.
Open Source SWG Features
Open Source Secure Web Gateway is based on Linux distribution. It uses the combination of Apache, Squid, and OpenSwan to build a high-performance web gateway. Apache is a lightweight web server and HTTP proxy server.
The ability of Squid to cache content, as well as its flexible authentication schemes, allow you to restrict access to certain websites or types of content. Also, this Squid provides additional security through the use of caching rules. Squid supports transparent proxying and SSL offloading.
OpenSwan is an IPsec implementation for Linux, providing both host-to-host and host-to-network authentication and encryption. So using OpenSwan as a VPN server, you can build a VPN network for SMEs. An availability monitoring feature that notifies administrators of potential network outages and helps administrators ensure continuous connectivity with their customers or partners in real-time.
A centralized management console reduces administrative overhead. This is with a flexible role-based management model. Also, it enables administrators to delegate administration while maintaining central oversight of the entire solution.
Cloud security: Symantec Management Platform
This is a management framework that enables administrators to monitor all managed devices in real-time via a single system. It tracks the status of virtual machines (VMs) hosted within an enterprise. A “Web Security Service” provides an easy mechanism for security administrators.
It manages multiple Symantec Secure Web Gateways. This enhanced user experience through usability enhancements. Also, it assists users in self-register and changing their passwords themselves. This platform helps users to manage their cookies.
