Havana Cuba. — Tinywall is a program firewall (firewall) designed for Windows users looking to protect their privacy and security online. For Cubans, this software serves a double purpose, allowing them to protect themselves against cyber attacks and save bandwidth.
The function of previous versions and the current one (3.3), which is available for free, consists of managing Internet traffic on a computer.
Programs of this type work like a policeman guarding a door to decide who goes in or out. In this case, its ease of use is one of the main advantages, even for those who do not have experience configuring a firewall.
The app, just over two megabytes, works automatically in the background, monitoring incoming and outgoing connections and blocking any unauthorized traffic, significantly reducing the amount of data transferred in an online browsing session. This feature is especially useful in Cuba, where Internet access can be expensive and limited, and where users rely heavily on purchased data packages for their connection to the network. It also helps users of Nauta Hogar, ETECSA’s service for homes in Cuba, as it maintains a good bandwidth most of the time.
Taking advantage of these advantages, devices such as PCs can be connected to the Internet through mobile data, since the firewall is in charge of preventing mobile data from running out quickly. At the same time, it helps prevent the spread of malware and other malicious programs that can damage a PC or compromise user privacy.
Some essential program options
After installation, TinyWall blocks most communications; however, the first step should be to grant it administration permissions so that it can work properly and thus configure it without problems.
To grant it administration privileges on the PC that is installed, you have to right-click on its icon in the Windows taskbar, which is normally located in the lower right part, and touch the “Raise privileges” option.
Afterwards, it is convenient to start giving connection permissions only to those applications that require Internet access at the time of use. This action is performed only once and Tinywall has several ways to do it. The most practical and easiest is “allow program by window”.
The “Change mode” option will always be at hand, which helps to block all traffic at a time of attack and it is not known where it comes from, allow only outgoing traffic, self-learning and disable the firewall. Each of these states are indicated in the program by means of colors.
Finally, if the computer needs to connect with other computers on the same network, the “Unblock local network traffic” option is activated. If you want to delve deeper into the options, you can access its official page, specifically the section on frequent questions.
