Laptop disk encryption

In general it is recommended that you encrypt your laptop storage (disk). Encrypting the storage protects your data against the risks of theft and loss. It also protects the whole Institute as if, for example, a laptop is stolen and a user account password taken then an attacker could get into our computer network from outside.

You can lookup how to do this with your favourite search engine, for example: "encrypt disk MacOS" .
