There is an interesting story on The Register about a person working for NASA who got duped by a Nigerian fellow and installed malware on a government computer. The article does not tell if the employee got fired or not but this is a good example why large (well any really) businesses need a strict email security policy. As there are many good free e-mail services, there is no longer ANYONE needing to mix work and home emails. Check your home email at home. Some may think this is harsh, but how much money do companies spend in cleaning up the messes that non-company email usage creates?
