Strengthen your network security, navigate using a VPN

VPN(Virtual Private Network)It is a technology that allows the connection of one or more computers on a completely private network using the internet. VPN system is commonly used by companies that want their employees to access corporate resources from an internet connection in their home, hotel, etc. However, connecting an employee's computer to corporate resources is only a function of a VPN. In conjunction with the above, a correct implementation of this technology allows ensuring the confidentiality and integrity of information.

Through a VPN it passes sensitive and confidential information from companies, which could be harmful if such information falls into the wrong hands, the risk increases even more if the employee connects to a public network.

Fortunately, this problem can be mitigated by encrypting the data that is sent and received. In order to achieve this goal, the following protocols can be used:

IPsec (Internet Protocol Security):allows you to improve security through robust encryption algorithms and a more comprehensive authentication system. IPsec has two encryption methods, transport mode and tunnel mode. It also supports encryption of 56 bit and 168 bit (triple DES).

PPTP/MPPE:technology developed by a consortium of several companies. PPTP supports several VPN protocols with 40 bit and 128 bit encryption using the Microsoft Point to Point Encryption (MPPE) protocol. PPTP alone does not encrypt the information.

L2TP/IPsec (L2TP on IPsec):technology capable of providing the IPsec level of protection over the L2TP tunnel protocol. Like PPTP, L2TP does not encrypt the information itself. A VPN network provides the highest possible level of security through Security

How a VPN offers online security

A VPN provides security because it greatly encrypts all your Internet traffic, even before it reaches the VPN server. It also guides data traffic through a much safer VPN tunnel. This makes it much more difficult for others, such as governments and hackers, to intercept and  see your data. Furthermore, it is especially important when using a VPN when using (dangerous) public WiFi networks.

At home or at work, the use of a VPN can also be helpful. Providers such as NordVPN or ExpressVPN offer the highest levels of AES 256 encryption. With this kind of protection, you won't have to worry about someone collecting your data and using it against you.

Uses of a VPN

• Access to a work network while travelling.VPNs are often used for professionals who travel and need to enter their network while they are away. Using this method allows resources to be kept safe.
• Access to a home network while traveling.It can also be used to enter the computer that we left at home, as if we were using a LAN (Local Network Area). Hide the navigation data. For example, if you are using a public Wi-Fi, those that are available without password in restaurants and shopping centers, everything you visit that does not have HTTPS connection will be visible to anyone who knows where to look. Instead, if you have a VPN, all you can see is the connection to the VPN; everything else will be anonymous.
• Enter places with geographic blocking.Usually region blocking problems usually ask you to be in the United States. This happens with Hulu, Pandora or the Netflix catalog that is bigger and more complete in this country. Sometimes it also happens on certain YouTube videos. To avoid these restrictions, you only have to use a VPN that has location of USA or another country. Avoid censorship on the Internet. For those governments that decide to censor certain websites, a VPN works very well to access them without problems.
