What kind of security is needed for making a callout from apex?

There are various ways to secure callouts:

• Restrict the IP Addresses that the web service will accept calls from.
• Use the Salesforce.com Client Certificate (or use your own Cert) to do mutual SSL for the Callout.
• Put a HTTP header into the Callout to use some sort of Basic Auth
