For personal reference, I post here the five laws of cybersecurity as suggested by Nick Espinosa

• If there is a vulnerability, it will be exploited. No exceptions.
• Everything is vulnerable in some way. From minor to major, law number 2 is really inescapable
• Humans trust, even when they shouldn’t.
• With innovation comes opportunity for exploitation (e.g. Mirai botnet)
• When in doubt, see law 1.

Stay safe out there folk!
