In order to setup the web Gateway in an organization in a
securely manner, first thing that the implementation team need to understand is
the organizational needs. Implementing the web Gateway in an organization in a
securely manner is the most important and the challenging task as most of the
alerts comes from the web only. The traditional firewalls are not smart enough
to stop or defense against the modern virus attacks. Now a day’s most of the virus
or attacks come from web.
What is
Secure Web Gateway (SWG)?
A secure Web gateway is a type of security solution
that prevents unsecured traffic from internet (Outside network) entering an
internal network of an organization. It is used by enterprises to protect their
employees/users from accessing and being infected by malicious Web traffic,
websites and virus/malware.
It is generally implemented through a hardware/software gateway device. Some
of the Web gateway application level
control, data leakage prevention and virus/malware code detection.
The
reasons why most of the organizations/customer invest on secure web gateways
are as follows.
Malware
Malicious Software in short is called as Malware.
Malware is a can be a short program, code, software that has the power
to interrupt or to disturb the normal processing of either a standalone
computer or a group of computers connected together (Network) with the aim to
fetch the important information or to keep the track of your activity or to
provide the control of the computer to the attacker hands. The Virus,
Backdoor, Trojans, RAT, Spyware, and Adware they all fall under the
malware. The malware are designed only to cause harm to the computer. Some of
the malware (Virus) are designed in such a way if they entered in the
system can corrupt the operating system.
Every organization have antivirus installed in their network
and on the endpoints (Laptop, desktops, servers), but most antivirus are
ineffective against modern malwares. The malware infected system often need to
be format. Once the system got infected by malware, the malware quickly spreads
across the network by replicate itself in files. It is very hard, difficult, and
critical to detect the infection
Unauthorized
and Unapproved Software’s, applications & Social Media/Social Networking
Sites.
Most of the time it is observed that the users have the
habit to download movies, live streaming, playing online games, downloading
other applications and software which are not allowed in an organization as
they chock and consumes unwanted internet bandwidth. As many of this downloads
or sites are infected with malware and spyware putting security at risk.
The Secure Web Gateway filters (block) the traffic generated
by the unapproved applications. Application white-listing this one feature of secure web gateway for application control which is in the
liked, good list of both the customers and organizations.
Social
Media/Social Networking sits/Online Shopping Site.
Online social networking and shopping sites are best for
promoting the products and to be in touch with your old friend, relatives. As
this is the easy way to be in touch with friend, making your shopping easy by
simply choosing the product from the large scale of product and simply adding
to the card, but it takes a lot of employee time at the working time thus
reducing the productivity. By using Secure Web Gateway the organizations can
block all the requested social media sits at works.
Data Leak
Prevention (DLP).
Data loss prevention (DLP) is a strategy for making sure that
end users do not send sensitive or critical information outside the corporate
network.
Types
of DLP:
1.
Network DLP.
2.
Endpoint DLP.
