Presented by: Eissa Abdullah AL-OwayiedInstructor: Muhammad AL-Jawarneh

We Will focus more on these following Servers:

V.P.NProxy

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.

Example of a simple V.P.N connection

Saudi Arabia

United States

Saudi Arabia

United States

When hacker attacks, V.P.N finds another

path

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.

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Some I.S.P providers in different countries, didn’t change the outdated Wires cables for internet users, So V.P.N will shutdown everytime, thinking that it might be a hacker attack.

Proxy Server)) الوكيل الخادم

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.

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.

Thank you…
