 "Human is the weakest link in the information security chain" © almost every IT security specialist

In the digital age, one of the most important as well as the most difficult task is protecting personal data. Most often, the first thing you will see as a new user is the advice "do not show your username and password to anyone!". 

Nevertheless, the personal data is the main purpose of protection, there is, in addition to personal information,  exists other important information. It may be your project / dissertation / archive of the accounting report, which for some reason you have not yet sent to your boss. This information can be targeted by malefactors. They may use malware, that encrypts the contents of the hard drive and then demanding a ransom. This type of malware also known as ransomware.

However, although this scenario is terrible, there are a number of procedures that will avoid such a disastrous outcome.

1.Сopy the information to another storage medium besides your main hard drive, it can be a USB flash drive, external HDD/SSD, or even cloud storage. The more copies, the less chance of information loss. Of course, this increases the chance of "information leakage". In the case of confidential information, you should ensure that no one steals the flash drive, and that access to the cloud storage does not end up in the hands of third parties.

2.Update your operating system regularly. If the system says that an update is available, then you should not postpone it. It is possible that the developers have patched a hole in a vulnerability that could be dangerous for default user. An great example of human negligence is the Wannacry ransomware attack. Mostly it happened due to the fact that many people did not install an update that fixes a serious vulnerability in the system.

3.Install an antivirus program. Even though Windows 10 has its own antivirus system, there are many programs that do it more efficiently.

I'm not a security expert, but I think these three rules are enough to keep you safe against most malware.

 Kenshi: the cowboy coding. Kenshi is a survival-sandbox-RPG game in a post-apocalyptic,  "sword-punk"  setting. This game has a large community due to its well-developed world, interesting mechanics, and also because of charismatic characters like "Beep".  First five-six years it was developed by one person. To get by , he had to work minimum wage security guard job in the nights. However, then, when the game gained its first fans, the development group grew significantly. The developers do not have a specific plan of action, they are just trying to bring the game to the state of " the dream game ". For this reason, we can say that due to the lack of almost any plans, Kenshi is an example of cowboy coding.

 Estonia is a small country with a well-developed IT industry, which means that competition in this area is also very tough. Nowadays, you will not surprise anyone with a higher education and knowledge of Python (or JavaScript), so programmers, in order to be able to break into high positions, often try to know the widest possible range of languages. Now you can often see a programmer who knows at least 3-4 languages ​​besides Python well. The the requirements  all over the world    for programmers are the same everywhere, but due to the fact that Estonia is a relatively small country, programmers are in constant competition. On the one hand, this limits the total number of "workforce", but it also means that the skills and competence of programmers in Estonia can be significantly higher than in other countries, where the population can be significantly larger. The most important skills for a programmer right now is adaptability. The ability to work in pairs / small groups /

This invention seemed so innovative that it swept the Internet with a huge noise. Many news sites were releasing news that Cicret would “turn your hand into a full-fledged tablet.” After all this hype, it was no surprise that Cicret raised massive amounts of money through its crowdfunding company  Go Fund Me.
