This document discusses VPN and proxy servers. It defines a VPN as enabling secure transmission of data across shared public networks as if directly connected to a private network. A proxy server allows indirect network connections and is used for anonymously accessing blocked websites and removing online surveillance. Both VPNs and proxy servers can improve security, but VPNs find alternative routes when attacked and encrypt transmitted files, while proxy servers may slow connection speeds and be tracked by governments. Care should be taken in choosing servers to avoid theft of information or transmission of viruses.
2. We Will focus more on these following
Servers:
V.P.N
Proxy
3. What is V.P.N?.
V.P.N is an acronym for “Virtual Private
Network”.
الخاصة االفتراضية الشبكة
V.P.N enables computers to Send/Receive
data across shared in public networks(with
Security and Encryption) as if it were
directly connected to the private network.
7. Anything else?...
V.P.N Supports sending data to different
computers, with privacy and security, Sending
data through V.P.N Tunnel, and when Hacker
attacks, it find another way and build tunnel
with it. If hacker somehow stole the file, it
would be useless because the file will be
encrypted .
V.P.N is a Client/Server Software and Hardware
technology, there are different brands, and they
don’t necessarily connect to each other.
10. What is may be bad?.
If you have a slow connection speed,
it would be a terrible performance for
send/receive data for all clients.
Some I.S.P providers in different
countries, didn’t change the outdated
Wires cables for internet users, So
V.P.N will shutdown everytime,
thinking that it might be a hacker
attack.
12. What is Web Proxy Server?.
A computer network service that allows
clients to make indirect network
connections to other network services.
Proxy is used for many purposes, like
hacking, spamming, surfing blocked
websites, remove surfing surveillance,
Connecting secretly to outside computers
connecting Local computers to the
internet(In old days) and many other
things.
15. Proxy servers: multiple
connection for safety
IP Address:
3.3.3.3
IP Address:
2.2.2.2
IP Address:
1.1.1.1
IP Address:
4.4.4.4
IP Address:
5.5.5.5
16. Proxy servers: multiple
connection for safety
+ V.P.N Server
IP Address:
3.3.3.3
V.P.N Server
IP Address:
1.1.1.1
IP Address:
4.4.4.4
IP Address:
5.5.5.5
17. Anything else?...
You can connect to a Web proxy server
by either using applications, web
browsers, website proxies and etc.
Web Proxy and V.P.N can be used both
for safety, encryption and protection.
18. What is be bad?.
Web proxies can slow connection speed
performance, due to the distance
between the client and proxy servers.
always cause a threat to internet
websites. Governments try to indices
hackers by tracking them back to proxy
servers.
Proxy server providers can easily steal
client’s information, and send malicious
viruses back to their devices, so it’s
important to use firewall and V.P.N
Servers for your protection.
