Personal and corporate email security controls are important as sensitive information may be occasionally exchanged via email. The ISC site notes the importance of these controls.
Secure E-Mail Access
QUOTE: Recently attacks focused on e-mail security. In many cases, e-mail credentials were either brute forced, or retrieved from compromised databases (in some of these cases, password re-use was a contributing factor). Some of the challenges:
- the use of "cloud based" e-mail services like gmail.
- mobile access to e-mail
- access to e-mail from multiple devices
- e-mail encryption and authentication (PGP/S-Mime)
- e-mail forwarding security (if someone has e-mail forwarded to a personal e-mail address)
