Assalamualaikum steemians

How are you?Hope so everyone would be safe and sound just like me as I am also safe Alhamdulillah....

My today's topic to share is all about virtual private network so I would like to delve into its various aspects.

If I talk about virtual private network then this is a technology which is used for creation of secure and encrypted connection in between device of a user and a network typically at internet. This is a connection which is used for permitting users to assess and transmit there information over internet in our safe way and protection of their online identification and sensitive data from any kind of unauthorised access.

If I talk about usage of virtual private networks then in most of our routine workout while using mobile phone all computers we use it but if we are using then we should also know about it working so these work by establishment of secure tunnel between device of user and VPN server.

That secure tunnel is encrypted by the use of different protocols like SSL/TLS etc for giving surety of data transmission by which it remains secret and confidential. After that VPN server forward encrypted data to its final place at internet which mask IP address and location of user.

If I talk about benefits of virtual private networks then these include enhancement of online safety, anonymity as well as freedom.By the encryption of internet traffic, virtual private networks are useful for protection of cyber dangers like hacks and eavesdropping.In addition to this virtual private networks are useful for permitting users for bypassing restrictions and accessing content which is blocked in their region.

If I talk about types of virtual private networks then first of all remote access virtual private networks comes which are used for connecting remote users with a network. There are also side to side virtual private networks comes which are used for connecting multiple networks.After that personal virtual private networks comes which are used for protection of individuals.Last but not least, business virtual private networks are useful for securing of enterprise networks.

If I talk about common VPN protocols then they include OpenVPN which is open source protocol.Thete is point to point tunnel protocol which is protocol supported widely.Layer 2 tunnel protocol is most secure protocol.Last but not least Secure socket tunnel protocol is Microsoft developed protocol.

There are multiple encryption methods which are used by virtual private networks for securing information.There are advanced standards encryption methods used widely.Secondly,there are rivest shamir adleman which is asymmetric encryption algorithm.After that secure hash algorithms are present which are hashing algorithms.

If I talk about internet speed and its relation with virtual private network then definitely these can effect speed of internet because there are many modern virtual private networks that are optimising performance but there are different factors which affect virtual private network speed and these are distance from server ,protocol of encryption as well as internet connection speed.

Virtual Private Networks are used for securing enhancement but still risks exists in which first of all a weakest encryption comes,after that vulnerable servers,malware infected VPN software comes.Lsst but not least vulnerable servers is also a big risk.So now you guys have understood about its working, security and related risks involved.

That's all about today's topic....
Don't forget to share your feedback!
