Why is it easy for everyone to overlook the security of physical servers?
I think there are several possible reasons for this:
Server devices are typically placed in a relatively secure room, usually behind a corporate firewall
The number of people who have access to the equipment is limited
Problems found on physical devices are usually not resolved by the user or cannot be resolved by installing defense software
It is not easy to attack, after all, this era can attack the physical device in a way far from attacking the virtual device's many
So users do not care, operation and maintenance personnel do not care, manufacturers are also convenient. But is that really okay? Obviously not. As the saying goes, "foreign thief is easy to Prevent, thief", assuming
