Security issues:

For physical security we use blocks bolted to tables with cables run through multiple hex bolts attached to the machines and through keyed locks attached to the machines. We also use copper fittings (collars) to secure our keyboards and mice. We use different size fittings depending on the connecter and we crimp the fitting as appropriate. Multiple device cables can go through one fitting with the security cable looped through to secure the connecters. Plumbing supply stores have boxes of fittings.

Hex nut with cable end. Small fitting with keyboard cable and security cable running through it.

Medium size fitting (crimped) with security cable looped through it and lock (off to the right). Keyboard and mouse cables run through fitting.

Large fitting with power cables and security cable running through it. We'll use these to secure power strips and other cords.
