Пристрої Internet of Things побудовані з урахуванням витрат і зручності, а не безпеки. Це робить їх легкими мішенями для кіберзлочинців, які хочуть використовувати уразливість пристроїв і впровадитися в ваші системи.

З чого "зроблені" сертифікати для Wi-Fi і з чого "зроблені" SSL сертифікати для HTTPS

Нижче наведені "нутрощі" Wi-Fi і стандартного SSL сертифікату для adgrafics.net детальніше можна роздягнути сертифікат тут
