A proxy server is a system or router that provides a gateway between users & the internet. Therefore, it helps prevent cyber attackers from entering a private network. It is a server, referred lớn as an “intermediary” because it goes between end-users & the web pages they visit online.
Bạn đang xem: Proxy definition & meaning
When a computer connects khổng lồ the internet, it uses an IP address. This is similar to lớn your home’s street address, telling incoming data where khổng lồ go & marking outgoing data with a return address for other devices to lớn authenticate. A proxy hệ thống is essentially a computer on the internet that has an IP address of its own.
Proxies provide a valuable layer of security for your computer. They can be mix up as website filters or firewalls, protecting your computer from mạng internet threats lượt thích malware.
This extra security is also valuable when coupled with a secure web gateway or other email security products. This way, you can filter traffic according to its màn chơi of safety or how much traffic your network—or individual computers—can handle.
How khổng lồ use a proxy? Some people use proxies for personal purposes, such as hiding their location while watching movies online, for example. For a company, however, they can be used to lớn accomplish several key tasks such as:Improve securitySecure employees’ internet activity from people trying to snoop on themBalance mạng internet traffic khổng lồ prevent crashesControl the websites employees và staff access in the officeSave bandwidth by caching files or compressing incoming traffic
Because a proxy server has its own IP address, it acts as a go-between for a computer và the internet. Your computer knows this address, & when you send a request on the internet, it is routed khổng lồ the proxy, which then gets the response from the web server và forwards the data from the page to your computer’s browser, lượt thích Chrome, Safari, Firefox, or Microsoft Edge
There are hardware và software versions. Hardware connections sit between your network & the internet, where they get, send, & forward data from the web. Software proxies are typically hosted by a provider or reside in the cloud. You tải về and install an application on your computer that facilitates interaction with the proxy.
Often, a software proxy can be obtained for a monthly fee. Sometimes, they are free. The miễn phí versions tend to lớn offer users fewer addresses and may only cover a few devices, while the paid proxies can meet the demands of a business with many devices.
To get started with a proxy server, you have lớn configure it in your computer, device, or network. Each operating system has its own cài đặt procedures, so check the steps required for your computer or network.
In most cases, however, thiết đặt means using an automatic configuration script. If you want to vày it manually, there will be options lớn enter the IP address và the appropriate port.
A proxy hệ thống performs the function of a firewall và filter. The end-user or a network administrator can choose a proxy designed to lớn protect data & privacy. This examines the data going in & out of your computer or network. It then applies rules to lớn prevent you from having to expose your digital address to the world. Only the proxy’s IP address is seen by hackers or other bad actors. Without your personal IP address, people on the internet do not have direct access khổng lồ your personal data, schedules, apps, or files.
With it in place, web requests go to the proxy, which then reaches out and gets what you want from the internet. If the server has encryption capabilities, passwords & other personal data get an extra tier of protection.
Proxies come with several benefits that can give your business an advantage:Enhanced security: Can act like a firewall between your systems và the internet. Without them, hackers have easy access to your IP address, which they can use lớn infiltrate your computer or network.Private browsing, watching, listening, & shopping: Use different proxies khổng lồ help you avoid getting inundated with unwanted ads or the collection of IP-specific data.Access to location-specific content: You can designate a proxy vps with an address associated with another country. You can, in effect, make it look like you are in that country & gain full access lớn all the nội dung computers in that country are allowed to lớn interact with.Prevent employees from browsing inappropriate or distracting sites: You can use it to lớn block access to lớn websites that run contrary lớn your organization’s principles. Also, you can block sites that typically over up distracting employees from important tasks. Some organizations block social media sites lượt thích Facebook và others khổng lồ remove time-wasting temptations.
While all proxy servers give users an alternate address with which khổng lồ use the internet, there are several different kinds—each with its own features.
A forward proxy sits in front of clients & is used to lớn get data khổng lồ groups of users within an internal network. When a request is sent, the proxy hệ thống examines it lớn decide whether it should proceed with making a connection.
A forward proxy is best suited for internal networks that need a single point of entry. It provides IP address security for those in the network & allows for straightforward administrative control. However, a forward proxy may limit an organization’s ability to cater lớn the needs of individual end-users.
A transparent proxy can give users an experience identical to what they would have if they were using their home computer. In that way, it is “transparent.” They can also be “forced” on users, meaning they are connected without knowing it.
Transparent proxies are well-suited for companies that want lớn make use of a proxy without making employees aware they are using one. It carries the advantage of providing a seamless user experience. On the other hand, transparent proxies are more susceptible to certain security threats, such as SYN-flood denial-of-service attacks.
An anonymous proxy focuses on making internet activity untraceable. It works by accessing the mạng internet on behalf of the user while hiding their identity & computer information.
A transparent proxy is best suited for users who want lớn have full anonymity while accessing the internet. While transparent proxies provide some of the best identity protection possible, they are not without drawbacks. Many view the use of transparent proxies as underhanded, and users sometimes face pushback or discrimination as a result.
A high anonymity proxy is an anonymous proxy that takes anonymity one step further. It works by erasing your information before the proxy attempts to connect to lớn the target site.
The hệ thống is best suited for users for whom anonymity is an absolute necessity, such as employees who vị not want their activity traced back to lớn the organization. On the downside, some of them, particularly the không tính tiền ones, are decoys set up lớn trap users in order to lớn access their personal information or data.
A distorting proxy identifies itself as a proxy lớn a website but hides its own identity. It does this by changing its IP address to lớn an incorrect one.
Distorting proxies are a good choice for people who want lớn hide their location while accessing the internet. This type of proxy can make it look like you are browsing from a specific country and give you the advantage of hiding not just your identity but that of the proxy, too. This means even if you are associated with the proxy, your identity is still secure. However, some websites automatically block distorting proxies, which could keep an end-user from accessing sites they need.
Data center proxies are not affiliated with an internet service provider (ISP) but are provided by another corporation through a data center. The proxy vps exists in a physical data center, and the user’s requests are routed through that server.
Data center proxies are a good choice for people who need quick response times và an inexpensive solution. They are therefore a good choice for people who need to lớn gather intelligence on a person or organization very quickly. They carry the benefit of giving users the power lớn swiftly & inexpensively harvest data. On the other hand, they vày not offer the highest level of anonymity, which may put users’ information or identity at risk.
A residential proxy gives you an IP address that belongs lớn a specific, physical device. All requests are then channeled through that device.
Residential proxies are well-suited for users who need to verify the ads that go on their website, so you can block cookies, suspicious or unwanted ads from competitors or bad actors. Residential proxies are more trustworthy than other proxy options. However, they often cost more money khổng lồ use, so users should carefully analyze whether the benefits are worth the extra investment.
A public proxy is accessible by anyone free of charge. It works by giving users access to its IP address, hiding their identity as they visit sites.
Public proxies are best suited for users for whom cost is a major concern & security and speed are not. Although they are free and easily accessible, they are often slow because they get bogged down with không tính phí users. When you use a public proxy, you also run an increased risk of having your information accessed by others on the internet.
Shared proxies are used by more than one user at once. They give you access to lớn an IP address that may be shared by other people, và then you can surf the mạng internet while appearing to browse from a location of your choice.
Shared proxies are a solid option for people who vì not have a lot of money lớn spend và do not necessarily need a fast connection. The main advantage of a shared proxy is its low cost. Because they are shared by others, you may get blamed for someone else’s bad decisions, which could get you banned from a site.
A secure sockets layer (SSL) proxy provides decryption between the client and the server. As the data is encrypted in both directions, the proxy hides its existence from both the client và the server.
These proxies are best suited for organizations that need enhanced protection against threats that the SSL protocol reveals and stops. Because Google prefers servers that use SSL, an SSL proxy, when used in connection with a website, may help its tìm kiếm engine ranking. On the downside, content encrypted on an SSL proxy cannot be cached, so when visiting websites multiple times, you may experience slower performance than you would otherwise.
A rotating proxy assigns a different IP address to lớn each user that connects khổng lồ it. As users connect, they are given an address that is chất lượng from the device that connected before it.
Rotating proxies are ideal for users who need to vì a lot of high-volume, continuous website scraping. They allow you lớn return khổng lồ the same website again and again anonymously. However, you have khổng lồ be careful when choosing rotating proxy services. Some of them contain public or shared proxies that could expose your data.
Unlike a forward proxy, which sits in front of clients, a reverse proxy is positioned in front of website servers và forwards requests from a browser to the website servers. It works by intercepting requests from the user at the network edge of the web server. It then sends the requests to and receives replies from the origin server.
Reverse proxies are a strong option for popular websites that need khổng lồ balance the load of many incoming requests. They can help an organization reduce bandwidth load because they act like another web server managing incoming requests. The downside is reverse proxies can potentially expose the HTTP server architecture if an attacker is able khổng lồ penetrate it. This means network administrators may have lớn beef up or reposition their firewall if they are using a reverse proxy.
On the surface, proxy servers và virtual private networks (VPNs) may seem interchangeable because they both route requests và responses through an external server. Both also allow you lớn access websites that would otherwise block the country you’re physically located in. However, VPNs provide better protection against hackers because they encrypt all traffic.
If you need lớn constantly access the internet to send và receive data that should be encrypted or if your company has to reveal data you must hide from hackers and corporate spies, a VPN would be a better choice.
If an organization merely needs khổng lồ allow its users to lớn browse the mạng internet anonymously, a proxy hệ thống may do the trick. This is the better solution if you simply want khổng lồ know which websites team members are using or you want khổng lồ make sure they have access to lớn sites that block users from your country.
A VPN is better suited for business use because users usually need secure data transmission in both directions. Company information và personnel data can be very valuable in the wrong hands, & a VPN provides the encryption you need khổng lồ keep it protected. For personal use where a breach would only affect you, a single user, a proxy server may be an adequate choice. You can also use both technologies simultaneously, particularly if you want to lớn limit the websites that users within your network visit while also encrypting their communications.
