Your company has recently adopted a new security policy that states that all confidential e-mails must be signed using a digital signature. Discuss what may be provided or considered for the implementation of this technology and associated policy. First discuss encryption, non-repudiation, or authentication. Consider addressing where this fits into the key elements of confidentiality, integrity and availability (CIA?). Other policy implications for email may include geo-blocking, or anti-virus checks; include these in your policy discussion as you desire but focus on digital signature policy this week. Responses may be a mix of the above. You decide.
