Proxy server Wikipedia. Communication between two computers shown in grey connected through a third computer shown in red acting as a proxy. Bob does not know to whom the information is going, which is why proxies can be used to protect privacy. In computer networks, a proxy server is a server a computer system or an application that acts as an intermediary for requests from clients seeking resources from other servers. A client connects to the proxy server, requesting some service, such as a file, connection, web page, or other resource available from a different server and the proxy server evaluates the request as a way to simplify and control its complexity. Proxies were invented to add structure and encapsulation to distributed systems. Today, most proxies are web proxies, facilitating access to content on the World Wide Web, providing anonymity and may be used to bypass IP address blocking.

A proxy server that passes unmodified requests and responses is usually called a gateway or sometimes a tunneling proxy. A forward proxy is an Internet facing proxy used to retrieve from a wide range of sources in most cases anywhere on the Internet. A reverse proxy is usually an internal facing proxy used as a front end to control and protect access to a server on a private network. A reverse proxy commonly also performs tasks such as load balancing, authentication, decryption or caching. Open proxiesedit. An open proxy forwarding requests from and to anywhere on the Internet. An open proxy is a forwarding proxy server that is accessible by any Internet user. Gordon Lyon estimates there are hundreds of thousands of open proxies on the Internet. An anonymous open proxy allows users to conceal their IP address while browsing the Web or using other Internet services. There are varying degrees of anonymity however, as well as a number of methods of tricking the client into revealing itself regardless of the proxy being used. Reverse proxiesedit. A reverse proxy taking requests from the Internet and forwarding them to servers in an internal network. Those making requests connect to the proxy and may not be aware of the internal network. A reverse proxy or surrogate is a proxy server that appears to clients to be an ordinary server. Requests are forwarded to one or more proxy servers which handle the request. The response from the proxy server is returned as if it came directly from the original server, leaving the client no knowledge of the origin servers. Reverse proxies are installed in the neighborhood of one or more web servers. All traffic coming from the Internet and with a destination of one of the neighborhoods web servers goes through the proxy server.

CGIPassAuth allows scripts access to HTTP authorization headers such as Authorization, which is required for scripts that implement HTTP Basic authentication. The use of reverse originates in its counterpart forward proxy since the reverse proxy sits closer to the web server and serves only a restricted set of websites. There are several reasons for installing reverse proxy servers Encryption SSL acceleration when secure web sites are created, the Secure Sockets Layer SSL encryption is often not done by the web server itself, but by a reverse proxy that is equipped with SSL acceleration hardware. Furthermore, a host can provide a single SSL proxy to provide SSL encryption for an arbitrary number of hosts removing the need for a separate SSL Server Certificate for each host, with the downside that all hosts behind the SSL proxy have to share a common DNS name or IP address for SSL connections. This problem can partly be overcome by using the Subject. Alt. Name feature of X. Load balancing the reverse proxy can distribute the load to several web servers, each web server serving its own application area. In such a case, the reverse proxy may need to rewrite the URLs in each web page translation from externally known URLs to the internal locations. Servecache static content A reverse proxy can offload the web servers by caching static content like pictures and other static graphical content. Compression the proxy server can optimize and compress the content to speed up the load time. Spoon feeding reduces resource usage caused by slow clients on the web servers by caching the content the web server sent and slowly spoon feeding it to the client. This especially benefits dynamically generated pages. Security the proxy server is an additional layer of defence and can protect against some OS and Web Server specific attacks. However, it does not provide any protection from attacks against the web application or service itself, which is generally considered the larger threat. Extranet Publishing a reverse proxy server facing the Internet can be used to communicate to a firewall server internal to an organization, providing extranet access to some functions while keeping the servers behind the firewalls. If used in this way, security measures should be considered to protect the rest of your infrastructure in case this server is compromised, as its web application is exposed to attack from the Internet. Monitoring and filteringeditSecondary market brokerseditNot to be confused with secondary market, secondary market brokers use web proxy servers to buy large stocks of limited products such as limited sneakers5 or tickets. Content control softwareeditA content filtering web proxy server provides administrative control over the content that may be relayed in one or both directions through the proxy. It is commonly used in both commercial and non commercial organizations especially schools to ensure that Internet usage conforms to acceptable use policy. A content filtering proxy will often support user authentication to control web access. It also usually produces logs, either to give detailed information about the URLs accessed by specific users, or to monitor bandwidth usage statistics. It may also communicate to daemon based andor ICAP based antivirus software to provide security against virus and other malware by scanning incoming content in real time before it enters the network. Many work places, schools and colleges restrict the web sites and online services that are accessible and available in their buildings. Governments also censor undesirable content. This is done either with a specialized proxy, called a content filter both commercial and free products are available, or by using a cache extension protocol such as ICAP, that allows plug in extensions to an open caching architecture. Ironically, websites commonly used by students to circumvent filters and access blocked content often include a proxy, from which the user can then access the websites that the filter is trying to block. Requests may be filtered by several methods, such as a URL or DNS blacklists blacklist, URL regex filtering, MIME filtering, or content keyword filtering. Some products have been known to employ content analysis techniques to look for traits commonly used by certain types of content providers. Blacklists are often provided and maintained by web filtering companies, often grouped into categories pornography, gambling, shopping, social networks, etc. Assuming the requested URL is acceptable, the content is then fetched by the proxy.

For example, JPEG files could be blocked based on fleshtone matches, or language filters could dynamically detect unwanted language. If the content is rejected then an HTTP fetch error may be returned to the requester. Most web filtering companies use an internet wide crawling robot that assesses the likelihood that a content is a certain type. The resultant database is then corrected by manual labor based on complaints or known flaws in the content matching algorithms. Some proxies scan outbound content, e. Change my Password. Changing Passwords for Personal Devices and Accounts. If you have any devices or accounts that are protected by passwords, you know that you have personal information that needs to be protected. Even if it is simply for email, or as important to your privacy as securing wireless network access points from intruders, passwords provide important first line of security measures to ensure that you and your information stay safe. Devices are often safeguarded by passwords as well to prevent changes to hardware and compromising systems. Changing a password ensures that your old password does not have a chance to be guessed and provides fresh protection from hackers and unauthorized individuals. The Importance of Changing Your Passwords. Passwords are strings of characters, usually alphanumeric and special characters, used to allow certain individuals users, administrators, login handles access to restricted levels of the password protected medium. Only if the individual knows the proper password and login handle can they be granted unrestricted access to the level of access allowed for such a user. Password protection can be applied to almost anything and is used in many more emerging technologies. Generating a Strong Password. No matter what the application or mode of usage for your passwords, such as hardwaresoftware security or default account passwords, you will want to ensure that the passwords are tough to crack against any type of intruder. There are many measures you can take towards creating a secure password for authentication which makes it much more difficult to gain access to restricted materials and network resources. Usually, you will want your passwords to be easy to remember, but random enough that someone who simply guesses words or numbers such as birthdays and anniversaries cannot gain access easily. The best way to go about this is to include an even mixture of uppercase, lowercase letters, numbers and special characters such as dollar signs or other random characters that would be impossible to simply guess. It is also recommended that you use the maximum amount of characters allowed for the password to ensure that it is as difficult as possible to guess or systematically force access into through random password generating software and devices. It is best to use passwords that are not found in dictionaries and to vary it more than attaching some special characters to it. The best passwords possible are random strings of characters and numbers that do not make any sense at all. These passwords may be too difficult to remember for most people but they are the best line of defense that any normal person could have at their disposal. Frequency of Change and Reuse of Previous Passwords. It may be best to have a set schedule that you follow to change your passwords and generate unique and different passwords to allow better protection. Frequent changes are great, but reusing the same password within a 1. If you must reuse the same password, then make sure that at least 6 months have gone by since you used that password to ensure access to your accounts is least likely done by people who knew your password but have since then forgotten it. Keeping Your Passwords Secret. If you have your password easily available to others, or not well hidden, you can compromise your private data and access to your important accounts. You either need to keep passwords to yourself in your own mind or create reminders of what the password is that will not completely give the password away to people who know your personal history or knowledge about your life. Password management software is available for most computer systems that can help you keep your passwords safe and easily accessible to you if you make especially strong passwords that are difficult to remember. Resetting Passwords When Loss of Access Occurs. In the event that you forget your passwords or lose access to wherever you keep your passwords available through any situation you may need to reset or change your password before you regain access to your accounts. There are many systems that may or may not be available for use to you when you need to reset and enter a new password. The most common system will require you to answer security questions to reset your password or allow an email to be sent to your email address to reset the password. The most secure password systems do not allow this type of password change requests through the simple interface and may require more extensive methods such as getting a hold of support representatives and providing proof of identity before access to resetting a password is allowed. Proper Contact of Support for Password Recovery. You will need to contact a support system by either email or phone to gain access to password recovery for some accounts and devices. Make sure that you get the official support contact details from user manuals or through the website of your account services before you send any information out. You do not want to disclose personal information with someone that is not part of the recovery process. You will need to also ask what the proper procedure is and provide account details to verify that you are the actual account holderowner. Once you provide everything they need in terms of verification information, you will then be given options to restore access to accountsdevices. It may be in the form of instructions or master passwords generated to help you for the one instance. Depending on what kind of password recovery options you are given, you may simply be provided with a link to change password details for accounts associated with online services. If there are no options available for account or device password recovery when you cannot change your password normally, then you may lose access to such devices and accounts permanently. It is important to always set up secondary password access for any service that allows it. This prevents the permanent loss of account services and provides you with increased security options.
