In companies, internet access has multiple advantages, but also some drawbacks that can cause productivity and security problems. A proxy server improves privacy when browsing the web.<\/p>\n\n\n\n

What is a proxy server?<\/h1>\n\n\n\n

A proxy server<\/strong><\/a> acts as a mediator between two computer systems. It transmits the requests of a client through the appropriate IP to a destination computer.<\/p>\n\n\n\n

This means that there is no direct communication between sender and recipient. A proxy server can act in two ways:<\/p>\n\n\n\n

Proxy forwarding (forward proxy): It protects the client network against possible problems that may cause Internet. It is installed between a private network (LAN) and the internet. In this way, the proxy takes care of any request that comes from the LAN, transmitting it as a sender to the destination computer. The response does not go directly to the client but passes through the proxy before reaching the LAN.<\/p>\n\n\n\n

Reverse proxy (reverse proxy): In this case, if the target system is protected by a proxy. It is interleaved when accessing from a public network, so the proxy receives the requests, checking the security, and then transmits them if the requirements for it are met.<\/p>\n\n\n\n

A proxy is a component of the Firewall that protects computer systems from possible attacks that come from a public network.<\/p>\n\n\n\n

Roles of a proxy server<\/h1>\n\n\n\n

A proxy server has several functions:<\/p>\n\n\n\n

Filtering: A proxy installed as an interface between two computer systems can be used to filter the transmission of data, block certain web content or directly reject those requests that are anomalous.<\/p>\n\n\n\n

Temporarily caches a copy of the collected data so that when requested, it is delivered directly, thus saving bandwidth.<\/p>\n\n\n\n

Control bandwidth and load distribution by distributing resources for clients according to load capacity, preventing applications from blocking bandwidth completely.<\/p>\n\n\n\n

A proxy server allows some anonymity as there is no direct connection between sender and recipient.<\/p>\n\n\n\n

Types of proxy servers<\/p>\n\n\n\n

There are the following types of proxy servers:<\/p>\n\n\n\n

Application proxy server:  Analyzes data packets according to certain rules and, by them, modifies, forwards, or blocks them.<\/p>\n\n\n\n

Circuit proxy server<\/strong><\/a>:  It is used as a Firewall filter module, allowing data to be filtered through ports and IP addresses.<\/p>\n\n\n\n

Dedicated proxy:  It is configured for a specific communication protocol.<\/p>\n\n\n\n

Generic proxy:  It is used in different communication protocols as it is not a specialized server.<\/p>\n","protected":false},"excerpt":{"rendered":"
