What is proxy server?
In computer networkinga proxy
server is a server application or appliance that acts as
an intermediary for requests from clients seeking resources
from servers that provide those resources. A proxy server thus functions
on behalf of the client when requesting service, potentially masking the true
origin of the request to the resource server.
Instead of connecting directly to a server that can fulfill a
requested resource, such as a file or web page, the client directs the
request to the proxy server, which evaluates the request and performs the
required network transactions. This serves as a method to simplify or control
the complexity of the request,[2] or provide additional
benefits such as load balancing, privacy, or security. Proxies were devised to
add structure and enacapsluation to distributed
systems.
Proxy server types
A proxy server may reside on the user's local computer, or at
any point between the user's computer and destination servers on the Internet.
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 data 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, authentication, decryption and caching.
Open proxies
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. As of 2008, Gordon Lyon estimates that "hundreds of thousands" of open
proxies are operated on the Internet.
·
Anonymous
proxy – This server
reveals its identity as a proxy server, but does not disclose the originating
IP address of the client. Although this type of server can be discovered
easily, it can be beneficial for some users as it hides the originating IP
adress
·
Transparent
proxy – This server
not only identifies itself as a proxy server, but with the support of http
header fields such as X-Forwarded-For, the originating IP address can be retrieved as well. The main benefit
of using this type of server is its ability to cache a website for faster
retrieval.
Reverse proxies
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. Reverse proxies
forward requests to one or more ordinary servers that handle the request. The
response from the proxy server is returned as if it came directly from the
original server, leaving the client with no knowledge of the original server.[6] 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 neighborhood's web servers goes through
the proxy server. 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 socket 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 a ll 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 SubjectAltName feature of X.509 certificates.
·
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).
·
Serve/cache static
content: A reverse proxy can offload the web servers by caching static content
like pictures and other static graphical content.
·
Compresion: 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 defense 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. A 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.
Content filtering proxy servers will often support user authentaction to
control web access. It also usually produces logs, either to give
detailed information about the URLs accessed by specific users or to
monitor bandwith usage
statistics. It may also communicate to deamon -based
and/or 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 workplaces, schools, and colleges restrict 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.
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
blacklist, URL regex
filtering, MIME filtering, or content keyword filtering. 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. At this point, a dynamic filter may be applied on the
return path. 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 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.g., for data loss
prevention; or scan content for malicious software.
