A VPN (Virtual Private Network) extends a private network across a public network, such as the
Internet.
A VPN is a network that uses a public telecommunication infrastructure, such as the Internet, to provide
remote offices or individual users with secure access to their organization's network. A VPN ensures
privacy through security procedures and tunneling protocols such as the Layer Two Tunneling Protocol
(L2TP). Data is encrypted at the sending end and decrypted at the receiving end.
Overview of VPN protocols.
VPNs (Virtual Private Networks) are often viewed from the perspective of security with the goal of providing authentication and confidentiality.
However, the primary purpose of VPNs is to connect 2 topologically separated private networks over a public network (typically the Internet).
VPNs basically hook a network logically into another network so that both appear as one private local network.
Security is a possible add-on to VPNs. In many cases it makes perfectly sense to secure the VPNs communication over the unsecure public network.
VPN protocols typically employ a tunnel where data packets of the local network are encapsulated in an outer protocol for transmission over the public network.
The most important VPN protocols are IPSec, PPTP and L2TP. In recent years SSL/TLS based VPNs such as OpenVPN have gained widespread adoption.
This slide explains the design part as well as implementation part of the firewall. And also tells about the need of firewall and firewall capabilities.

In this slides i have mentioned some hacking tricks which are interesting to know.. You will able to know how the sites are blocked, how to get rid of them.You will also able to crack the passwords...And some useful tricks related to facebook and mobile hacking.. i hope,You will like it...But one thing ,the tricks are old...But what i think is Old is Gold. :p
A fingerprint in its narrow sense is an impression left by the friction ridges of a human finger.Human fingerprints are detailed, unique, difficult to alter, and durable over the life of an individual making them suitable as long-term markers of human identity and may be employed by police or other authorities to identify individuals who wish to conceal their identity, or to identify people are incapacitated or deceased and thus unable to identify themselves, as in the aftermath of a natural disaster. When this fact is integrated for authentication purpose ,it creates an amazing lock system for Security purpose.Here we discuss what is Information Security ,how it is enhanced with the help of Fingerprint , its advantages, disadvantages.You will get a overall end to end scenario infront of you after going through all the slides.

Solution
A virtual private network (VPN) is a technology that creates an encrypted connection over a less secure network. The benefit of using a VPN is that it ensures the appropriate level of security to the connected systems when the underlying network infrastructure alone cannot provide it. The justification for using a VPN instead of a private network usually boils down to cost and feasibility: It is either not feasible to have a private network (e.g., for a traveling sales rep) or it is too costly to do so. The most common types of VPNs are remote-access VPNs and site-to-site VPNs
A remote-access VPN uses a public telecommunication infrastructure like the Internet to provide remote users secure access to their organization\'s network. A VPN client on the remote user\'s computer or mobile device connects to a VPN gateway on the organization\'s network, which typically requires the device to authenticate its identity, then creates a network link back to the device that allows it to reach internal network resources (e.g., file servers, printers, intranets) as though it was on that network locally. A remote-access VPN usually relies on either IPsec or SSL to secure the connection, although SSL VPNs are often focused on supplying secure access to a single application rather than to the whole internal network. Some VPNs provide Layer 2access to the target network; these require a tunneling protocol like PPTP or L2TP running across the base IPsec connection.
A site-to-site VPN uses a gateway device to connect the entire network in one location to the network in another, usually a small branch connecting to a data center. End-node devices in the remote location do not need VPN clients because the gateway handles the connection. Most site-to-site VPNs connecting over the Internet use IPsec. It is also common to use carrier MPLS clouds rather than the public Internet as the transport for site VPNs. Here, too, it is possible to have either Layer 3 connectivity (MPLS IP VPN) or Layer 2 (Virtual Private LAN Service, or VPLS) running across the base transport.
VPNs can also be defined between specific computers, typically servers in separate data centers, when security requirements for their exchanges exceed what the enterprise network can deliver. Increasingly, enterprises also use VPNs in either remote-access mode or site-to-site mode to connect (or connect to) resources in a public infrastructure as a service environment. Newer hybrid-access scenarios put the VPN gateway itself in the cloud, with a secure link from the cloud service provider into the internal network.

Wireless communication involves the transmission of information over a distance without the help of wires, cables or any other forms of electrical conductors.
Wireless communication is a broad term that incorporates all procedures and forms of connecting and communicating between two or more devices using a wireless signal through wireless communication technologies and devices.
Features of Wireless Communication
The evolution of wireless technology has brought many advancements with its effective features.
The transmitted distance can be anywhere between a few meters (for example, a television's remote control) and thousands of kilometers (for example, radio communication).
Wireless communication can be used for cellular telephony, wireless access to the internet, wireless home networking, and so on.

2. What is a VPN?
A virtual private network (VPN) is a type of private network that
uses public telecommunication, such as the Internet, instead of
leased lines to communicate.
It enables a computer or network-enabled device to send and receive
data across shared or public networks as if it were directly connected
to the private network, while benefiting from the functionality,
security and management policies of the private network.
➢ Remote network communication through Internet
➢ Became popular as more employees worked in remote
locations.
➢ In order to gain access to the private network, a user must be
authenticated using a unique identification and a password.
➢Used by companies/organizations who want to communicate
confidentially
➢The Internet is used as the backbone for VPNs
3. Brief Overview of How it Works
Two connections – one is made to the Internet and the second is
made to the VPN.
Datagram's – contains data, destination and source information.
Firewalls – VPNs allow authorized users to pass through the
firewalls.
Protocols – protocols create the VPN tunnels.
Four Critical Functions
Authentication – validates that the data that sent from the sender.
Access control – limiting unauthorized users from accessing the
network.
Confidentiality – preventing the data to be read or copied as the
data is being transported.
Data Integrity – ensuring that the data has not been altered.
4. Types of VPN
3 Types
❑Remote Access – Employee to Business
❑Intranet – Within an organization
❑Extranet – Outside an organization
Remote-access-is a user-to-LAN connection used by a company
that has employees who need to connect to the private network from
various remote locations.
A good example of a company that needs a remote-access VPN
would be a large firm with hundreds of sales people in the field.
Remote-access VPNs permit secure, encrypted connections
between a company's private network and remote users through a
third-party service provider.
5. Intranet-based - If a company has one or more remote locations
that they wish to join in a single private network, they can create
an intranet VPN to connect LAN to LAN.
Extranet-based - When a company has a close relationship with
another company (for example, a partner, supplier or customer),
they can build an extranet VPN that connects LAN to LAN, and
that allows all of the various companies to work in a shared
environment.
VPN Protocols
` The number of protocols and available security features
continue to grow with time. The most common protocols are:
6. Point-to-point tunneling protocol (PPTP)
- PPTP has been around since the days of Windows 95.
- It can be easily setup on every major OS.
- It is still strong, but not the most secure.
L2TP/IPSec (Layer Two tunneling protocol /Internet Protocol
Security)
- L2TP over IPSec is more secure than PPTP and offers
more features. L2TP/IPsec is a way of implementing two
protocols together in order to gain the best features of
each.
Open VPN - The software used is open source and freely
available. OpenVPN can run on a single UDP or TCP
port, making it extremely flexible.
