In simple terms, a Virtual Private Network (VPN) is an internet security service that allows browsing safely through encryption and a secure connection. A good VPN can stop anyone and everything from tracking the sites you visit. Here are some of the most important security measures and benefits that the most popular VPNs have: File encryption, Deep packet inspection (DPI), Secure DNS (DNS) servers, Help to Disable ads, Increase the security of your data, etc. can overall protect your data and other sensitive information.
So, a good & paid VPN download is undoubtedly a prudent choice if you prioritize privacy over anything else. For corporate data protection and user access control, VPN always works.
How do VPNs help secure data?
As mentioned above, VPN works by establishing an encrypted connection between your device and the internet. Encryption is a form of data scrambling that restricts someone from data interception. Encryption takes readable data and alters it in a random manner so that no one can understand the real message except the intended recipient.
Usually, VPNs use IPsec or SSL/TLS encryption protocols. Encryption process runs in the back end and this adds a tiny bit of latency to your internet connections. So, you may experience slow network traffic but this shouldn’t hamper your daily activities.
Due to the encryption mechanism (which is mostly 256-bit encryption), your IP address remains hidden even if you are connected to public internet infrastructure. Let’s analyze an example.
Due to the pandemic situation, Sarah is working from home. She connects to her company network through a VPN which is authorized by the company. The company database is 300 kilometers away from Sarah’s location. All her requests to the ecompany database and the database’s response to her queries travel through a public Internet Service Provider (ISP) point.
Now imagine, a cybercriminal has infiltrated this ISP and tracking all data passing through the channel. Sarah’s data is absolutely secure because she is using a VPN connection. The cybercriminal can only see the encrypted version of data passing through the ISP and will not understand anything else.
How is access control maintained through VPN?
Access control is a crucial aspect that protects and secures corporate data. This also prevents potential data breaches, data alteration and unauthorized users. Let’s take another example to understand how VPN helps in access control management.
Square LLC. uses Server A and Server B in their office building and office devices are connected to any one server through Ethernet cables. Someone who is not physically connected to Server A will not get access to files, images or documents that are stored in Server A. The same applies to Server B.
If any person wants to get access to a file that is stored in Server B, he/she must plug into Server B with necessary approval from higher authority via Ethernet cable. This is how Square LLC. controls their access management inside the office building.
VPN works in a similar fashion except it doesn’t require any physical Ethernet cable. If someone’s computer has access to Server A, it will not get access to Server B unless it is connected to that server’s VPN connection. And changing access from one VPN to another VPN requires prior approval from top management.
Square LLC. can use Wi-Fi and VPN in their office building instead of physical cables or routers and easily maintain a robust access control management policy throughout the organization.
To sum up
For data protection and access control mechanisms use of a VPN is a great option. VPN has its encryption algorithm and several encryption protocols to secure data. Besides, the use of VPN can help organizations to establish a robust access control system.
Having well-maintained access controls prevents unauthorized access to sensitive data and prevents the violation of data breach policies. It is statistically verified that paid VPN works better than the free version of the same VPN.
