<div>
<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">There are several benefits of using a transparent proxy. First of all, for end users, a transparent proxy can enhance their web browsing performance by caching frequently accessed web content, while introducing minimal configuration overhead for them. For administrators, it can be used to enforce various administrative policies such as content/URL/IP filtering, rate limiting, etc.</span></span></div>

<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">A proxy server acts as an intermediary between a client and a destination server. The client sends requests to the proxy server which then evaluates the requests and takes necessary actions. In this tutorial, we will be setting up a web proxy server using Squid, which is a robust, customizable and stable proxy server. Personally, I had administered a Squid server with 400+ client workstations for about a year. Although I had to restart the service about once a month in average, CPU and storage utilization, throughput and client response time were all great.</span></span></div>

<div>
<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">The Preboot eXecution Environment (PXE, sometimes pronounced as pixie) specification describes a standardized client-server environment that boots a software assembly, retrieved from a network, on PXE-enabled clients. On the client side it requires only a PXE-capable network interface controller (NIC), and uses a small set of industry-standard network protocols such as DHCP and TFTP.</span></span></div>

<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">The concept behind the PXE originated in the early days of protocols like BOOTP/DHCP/TFTP, and as of 2015 it forms part of the Unified Extensible Firmware Interface (UEFI) standard. Given fast and reliable local area networks (LANs), PXE is the most frequent choice for operating system booting, installation and deployment.</span></span></div>

<span style="color: #222222; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">OpenVas began, under the name of GNessUs, as a fork of the previously open source Nessus scanning tool after Tenable Network Security changed it to a proprietary (closed source) license in October 2005. OpenVAS was originally proposed by pentesters at Portcullis Computer Security and then announced by Tim Brown on Slashdot.</span></span><br />
