#encryption protocols

Academic researchers have revealed in a paper published Thursday that a newly discovered vulnerability baked into Apple’s M-series of chips allows attackers to extract secret keys from Macs when they perform widely used cryptographic operations. Dan Goodin for Ars Technica: ‎ The flaw — a side channel allowing end-to-end key extractions when Apple chips run implementations of widely used…

Types of VPN protocols

The above two VPN types are based on different VPN security protocols. Each of these VPN protocols offer different features and levels of security, and are explained below:

1. Internet Protocol Security or IPSec:

Internet Protocol Security or IPSec is used to secure Internet communication across an IP network. IPSec secures Internet Protocol communication by authenticating the session and encrypts each data packet during the connection.

IPSec operates in two modes, Transport mode and Tunneling mode, to protect data transfer between two different networks. The transport mode encrypts the message in the data packet and the tunneling mode encrypts the entire data packet. IPSec can also be used with other security protocols to enhance the security system.

2. Layer 2 Tunneling Protocol (L2TP):

L2TP or Layer 2 Tunneling Protocol is a tunneling protocol that is usually combined with another VPN security protocol like IPSec to create a highly secure VPN connection. L2TP creates a tunnel between two L2TP connection points and IPSec protocol encrypts the data and handles secure communication between the tunnel.

3. Point – to – Point Tunneling Protocol (PPTP):

PPTP or Point-to-Point Tunneling Protocol creates a tunnel and encapsulates the data packet. It uses a Point-to-Point Protocol (PPP) to encrypt the data between the connection. PPTP is one of the most widely used VPN protocol and has been in use since the time of Windows 95. Apart from Windows, PPTP is also supported on Mac and Linux.

4. Secure Sockets Layer (SSL) and Transport Layer Security (TLS):

SSL (Secure Sockets Layer) and TLS (Transport Layer Security) create a VPN connection where the web browser acts as the client and user access is restricted to specific applications instead of entire network. SSL and TLS protocol is most commonly used by online shopping websites and service providers. Web browsers switch to SSL with ease and with almost no action required from the user, since web browsers come integrated with SSL and TLS. SSL connections have https in the beginning of the URL instead of http.

5. OpenVPN:

OpenVPN is an open source VPN that is useful for creating Point-to-Point and Site-to-Site connections. It uses a custom security protocol based on SSL and TLS protocol.

6. Secure Shell (SSH):

Secure Shell or SSH creates the VPN tunnel through which the data transfer happens and also ensures that the tunnel is encrypted. SSH connections are created by a SSH client and data is transferred from a local port on to the remote server through the encrypted tunnel.

Mobile Web: Why Is It So Important?

Mobile Web: Why Is It So Important?

Times have changed and the way we communicate also has undergone a lot of change.  Mobile phones and Smartphones have taken over our lives completely.  And with majority of the mobile phones offering the ‘smart’ options, it has become easy to access the internet on the handheld devices.  People now do not have to wait for getting back home to sit on their PC or open their big laptop to browse through the web while traveling.  They can just log into their mails and browse the internet through their mobile web.  

Therefore it has become very important that the online business enterprise owners make their websites compatible with the mobile phone browsers.  For the kind of population that is heavily relying on their mobile devices to accomplish a lot of their online activities it has become almost mandatory for the online business enterprise owners to have a mobile web representation of their business too.  By doing so they will not be able to lose out a potential segment of the market which they could lose if they did not make a foray into the arena.  

The benefits that the business owners are going to get by opting for a mobile web are numerous for the brand’s reach will really go far and wide.  The shopper may choose to contact the vendor almost immediately as he has the mobile phone in his hand.  And you are not bound to miss on those clients who are always on the move.

Mobile Web Advantages

There are in fact a lot many other advantages too that will come in with the mobile websites.  One can shop at highly reputable websites and of course care has to be taken about ensuring whether the encryption protocols are completely in their place so that the personal information is kept absolutely safe along with the credit card data.
