Recently, on one of the computers of the Ministry of Defense of Ukraine, we found an interesting lecture on cyber security. She didn't help the computer owner, but the lecture was written in a very logical way. Recommendations were developed at the SBU Institute. Yes, the Security Service of Ukraine in its modern form is our enemy. But the enemy must not be underestimated, there are many wise people among them. And that makes them twice as dangerous. The lecture analyzes in great detail the issues of data protection on computers and smartphones. It won't save you from experts of our level, but it can protect you from mass hacking. We know that these materials will interest many of our readers. And we recommend at least reading them. Computers and mobile phones are hacked not only by Russian security forces. Crooks are taking advantage of this in droves, and we know that our subscribers may also face similar threats. We are in Regina! We know everything!
