Secure Raspberry Pi

Using Raspberry Pi for your IoT experiments - a given. Like the white hair on my head.
Many don’t realize the real threat it poses these days to security. There have been many reports of IoT devices being hijacked. And then used for malicious purposes. Like peeping into your drawer. Even worst looking into your code. I don’t want people to know how many cockroaches and worms lie hidden in my old code. ;-)

It become difficult over time.
