Types of VPN Encryption Protocols

Encryption Protocols

A VPN provides a way for data transmission over internet through a public or shared network in such a way that the computing device seems to be actually connected to a private network. This is achieved by creating virtual tunneling protocols, dedicated connections, or encrypting the traffic. As a user you can enjoy many benefits of VPN such as managing network, providing security and hiding your identity on any network.

A VPN relies on encryption of data for safely and securely achieving the wireless transactions performed by a user. This can be done by encrypting the transmitted data at one end of the tunnel and then decrypting it at other end of the tunnel. This is where encryption protocols comes handy as only pair of keys can’t be used for a completely secured encryption.

If a user is outside office and he wants to access office intranet then the employee can securely access it using virtual private network. Even if an organization faces issues of having offices in various countries, then the distance can be reduced giving rise to a cohesive and coordinated network. This solves many issues faced due to remote locations. Any individual making wireless transactions can safely and securely achieve it through VPNs. Users can circumvent censorship, prohibited accesses to particular sites and many geographically restricted sites. In case of identity protection and location hideout connection using proxy servers can really help.

PTTP

The Point-to-Point Tunneling Protocol (PPTP) is one of the encryption protocols used for implementing virtual private networks. Point-to-Point Tunneling Protocol was founded by Microsoft using the idea of VPN over dialup networks. It has been a standard protocol for internal business since a long time. PPTP uses TCP and GRE tunnels to allow PPP packets to pass through them.

Review of Hide My Ass VPN

A VPN provides a secured network connection on the internet for connecting to a private network through a public network for transmitting and receiving data. The private network could be any network like an organization’s internal network, Bank websites and Government agency portals. A VPN protects your online browsing activities and keeps your identity anonymous as it encrypts the transmitted data and then re-routes it from its own remote servers. Thus, it helps you to access restricted websites from any location without the information getting intercepted and keeping your network location completely hidden.

VPN is designed in such a way that it acts as a secure and encrypted tunnel for transmitting data. The information gets transmitted through encrypted tunnel and nobody else can intercept or read the information in between. Also, the encryption mechanism makes sure that only the authorized user is able to access the transmitted information over the network. A VPN comes handy when you are accessing internet through public Wi-Fi hotspots as the wireless connection is not secure enough and can lead to information being compromised over the internet. Also, VPN would help you to access blocked websites over public Wi-Fi connection and prevent data theft.

What is a proxy? All you need to know about using a Proxy

What is a Proxy?

Proxy is basically a purposeful computer which serves as an intermediary hub between the endpoint device, like a computer or laptop, and the server which is being used to request a service from the user. All the internet requests gets processed through proxy servers. By letting the user to connect via one of these servers, the host computer can send the user requests to proxy server which in turn processes the request and finally returns the required result to the user which he wanted. So, in this manner proxy is actually serving as an intermediate between the user machine and all the remaining computers over the internet. These servers are generally located at user’s own system, or between destination servers on the internet and user’s system.

Proxy server remains invisible to the user. All requests sent over internet and their returned responses to the user appears to be associated with addressed Internet server. A proxy can exist as a firewall server on the same machine or it can be configured on an entirely different server, which in turn can forward the requests via firewall.

For any normal user having only some basic understanding of Computer and Internet, Ransomware can be considered as one of the most vulnerable and dangerous type of malware. If a user gets infected with it, he has no other choice than paying the ransom amount which can be up to few hundred dollars.

Private Internet Access: What is a VPN?

What is a VPN?

A Virtual Private Network – or VPN – allows you to send and receive data via the internet using a public network as if you were connected to a private network. In other words, it is a system that allow you to connect to a public network (a hotspot, for example) but acts as if you were connected to your company’s host computer. This makes it difficult to be located and greatly improves the security of your connection. But let’s not get too technical. Below you’ll find the principal uses of a VPN:

  • Access to services that are only available in some countries, principally audiovisual content (such as television shows, series or podcasts). For example, if you want to watch your favorite programs on Netflix or Hulu, but you are not in the United States, you can’t. Unless you use a VPN to access those website from a US server!
  • To send sensitive data (such as banking information) via an encrypted connection. Many people use these systems to protect their banking and personal information from being robbed by third parties when connected to public networks, and/or to maintain anonymity.
  • To create your own VPN and allow your employees to access your company’s private network, including if they are not physically connected to it.

The New 13 and 15 inch Retina Display MacBook Pros

The Macbook Pro is Apple’s top-of-the-line product. First introduced in 2006 and now in its third-generation, unibody aluminium guise, the Macbook is one of Apple’s most sought-after and hyped products. Now the Macbook is available with Apple’s new innovation: the retina screen. Essentially, a retina screen contains the maximum amount of pixels visible to the human eye, meaning that anything viewed on a retina screen should be indistinguishable from viewing an object in the real world with the naked eye.

Apple’s newest 13 and 15 inch offering come with 2,560×1,600 and 2,880×1,800 pixels respectively. Both laptops have dropped the optical drive, which makes them comparatively lightweight when considered against the older models.

As is to be expected with Apple products, you are absolutely forbidden from upgrading these laptops. The RAM chips are soldered in place and fixed at 8GB. The 13 inch version of the new Macbook retina series comes with an SSD card that you can’t remove either. Read more
