JAKARTA - Many roads lead to Rome. This proverb, when connected with the world of internet technology, is very fitting. Especially in breaking through the blocking of a certain site or web in the internet network.
One of them, of course, uses a VPN (Virtual Private Network). It is a piece of computer networking technology that can be used with the internet. Actually a VPN is a solution to increase security in surfing the internet.
However, it is often used by certain parties to penetrate the blocking of certain sites such as online gambling and porn sites that are carried out by the government or certain parties.
In the case that the Indonesian people can access Only Fans and see Dea's actions, then they are most likely using a VPN. Because the site has been blocked by the government.
VPN itself functions as a technology that is able to mask internet protocol (IP) addresses so that online actions are almost untraceable. The way it works is called tunneling, there is a network within the network. The main function of a VPN itself is to create a connection path in secret by taking advantage of other network structures.
VPN itself is highly recommended if we surf in cyberspace. Especially if you want to make financial transactions. Also serves to protect our data also using public wi-fi. A paid and trusted VPN will provide sufficient protection for our IP or other information to be hijacked by certain parties.
Through a VPN that is provided by a trusted source, it can even provide the benefit of maintaining good privacy for its users. On the other hand, if a VPN is used carelessly, it can actually threaten the privacy of its users. For example, data leaks, malware, and personal data theft occur.
The reason is that many free and easy VPN providers often use our data for their benefit. This is certainly dangerous.
Apart from being able to be used on a computer, either a PC or a laptop, it can also be used via an Android or iOS phone.
Using a VPN on a smartphone also allows users to access websites privately through other network servers. The point is that a VPN can connect a computer or smartphone to another device in a different place so you can access the internet using that connection.
VPN Security Method
1. Firewall
This is a "barrier" between the local network and the internet. The firewall can determine which ports are allowed to be opened, what packets are allowed to pass through the firewall, and what protocols are allowed.
2. Encryption
Encryption is a common method for securing data. Information will be "scrambled" in such a way that it is difficult for others to read. There are several commonly known encryption methods.
- Symmetric-key encryption
Here the sending and receiving computers must have the same "key". Information that has been encrypted can only be decrypted using that key.
- Public-key encryption
Here, the sending computer uses the receiving computer's public key to perform encryption. After the information is sent, the decryption process can be carried out using the recipient's computer's private key.
- public key
Through this public key can be distributed to anyone, but the private key is only for the rightful owner.
3. IPSec
This system provides better security features. Like a better encryption algorithm and comprehensive authentication. IPSec uses two encryption methods, namely:
- Tunnel, encryption on the header and payload of each packet.
- Transport, only encrypts the payload of each packet.
4. Data Integrity
Every data packet that is passed on a public network, there needs to be a guarantor of data integrity, whether or not there is a change in the data.
VPN Functions
Increase SpeedVPN can increase internet speed or speed. One of them is in terms of doing the process of downloading files or documents from the internet.
When using a VPN, the user is like using a private network, so the speed increases. Through a VPN, users can also connect directly to the data stream flowing on the internet, which can increase download speeds.
Covering Browsing ActivityVPN is very useful for people who need privacy while surfing the internet. Especially when browsing and want to access content that is very important and should not be seen by others. However, it is often used to view porn and gambling sites which are banned in some countries.
VPN is very helpful to hide internet activity from its users. The history of what the user has browsed on the internet will not be detected by others.
Accessing Blocked and Censored SitesVPNs are now very commonly used to get around things like accessing blocked and censored sites. Through VPN users can still access sites that have been previously blocked. In the case of Indonesia only Fans, Pornhub, and many gambling sites have been blocked, but through a VPN everything can be seen and accessed.
This is a common VPN abuse in Indonesia today. VPN can open dangerous sites such as porn sites, gambling sites, blocked terrorist sites and so on.
Safe Online TransactionsVPN from its function can secure online transactions. This will be very useful for people who have an online business and often transact online through the internet network.
Dangers of Free VPN
Threatening Device SecurityBesides being useful, VPNs are actually dangerous, especially Free VPNs. This can threaten the security of your device from the risk of hacking. According to recent studies, many free VPN applications have been infected by malware.
2. Slow Internet Network
Free VPNs usually contain a lot of ads that users have to watch. This of course becomes annoying to users and even confuses them and actually leads to dangerous sites.
3. Monitoring User Activity
Using a free VPN allows users to be monitored by the free service provider. There is a study that states that 72 percent of VPN applications contain third-party trackers.
4. IP for Network Endpoint
Free VPN service providers often use the IP address of their users' computers or PCs as Network Endpoints. This can be referred to as bandwidth sales.
5. Data and IP Address Leaks
Another danger of free VPNs is that data and IP addresses will be leaked to the public. Free VPN providers often leak DNS requests.
6. Man in the Middle
Free VPNs are particularly at risk of “Man In the Middle” attacks, which are attacks on computer systems that communicate with each other. The method of hacker attack is quite deadly, the concept is that the hacker is in the middle of the communication line.
Seeing the various advantages and disadvantages of using the VPN, it is better for us to use a paid VPN. But more importantly, use a VPN wisely to keep you safe in cyberspace.
