3.  A Distributed Denial of Service (DDoS) attack
is an attempt to make an online service
unavailable by overwhelming it with traffic
from multiple sources. They target a wide
variety of important resources, from banks to
news websites, and present a major challenge
to making sure people can publish and access
important information.

4.  Project Shield is a free anti-distributed-
denial-of-service (anti-DDoS) service that is
offered by Jigsaw, a subsidiary of Google's
parent company, Alphabet Inc. to websites
that have "media, elections, and human rights
related content.
 Project Shield is a free service that uses
Google technology to protect news sites and
free expression from DDoS attacks on the
web.

5.  Project Shield is a reverse proxy, Project
Shield servers receive traffic requests on your
website's behalf and then sends safe traffic to
your website's server.
 This protects your site against distributed
denial of service (DDoS) attacks in two ways:
1. Filtration of harmful traffic
2. Absorption of traffic through caching

6. Filtration of harmful traffic
Project Shield filters out harmful traffic using
Google’s technology and DDoS tools. If
someone tries to take your website down with
a DDoS attack, Project Shield can identify and
block harmful traffic so your website stays up
and running.

7. Absorption of traffic through caching
Project Shield can cache — or save — versions of
your content to serve to website visitors. This
reduces traffic requests to your website
server and absorbs potential DDoS attacks. For
example, if many visitors want to view the same
content on your website (or, in a DDoS attack, an
attacker is trying to overwhelm your website with
traffic), Project Shield will fetch the content from
your website's server once and then serve a
cached copy repeatedly.

9. Review traffic and filter out bad requests
Attacks are blocked
Content is served back to the user
Reverse proxy in Google's data centers

10. Review traffic and filter out bad requests
When someone visits your website, the
request comes to Project Shield first so that
we can filter out bad requests.
Attacks are blocked
If it looks like the traffic is an attack, we
reject the request and prevent it from
reaching your server.

11. Reverse proxy in Google's data centers
User requests enter Google’s network at a
location close to the end user, and then are
proxied through the nearest Google Cloud
data center. This improves performance and
reduces latency.

12.  Content is served back to the user
We retrieve the requested site content either
from our cache or from your server and send
it back to the user. By serving content from
cache, we reduce the load on your server and
improve performance for the end user.

13. 1. Protection from DDoS
2. Free of cost
3. Real-time site analytics
DISADVANTAGES
1. No protection from Hacker
2. Size Limitation

14.  Protection from Malicious intruder
 World wide Access
 More security

15.  This initiative by google is the long jump in
Information security.
 If this project is applied in a proper manner
this can be proved as a mile stone in the
cyber world .
