Question

which statement correctly describe the information security risks to most uses of email systems? ( choose all that apply)

A B с D U 0 Almost all emails are sent unencrypted, with content, file attachment content, and address and routing information open to anyone who chooses to intercept it. This also means that content can be altered en route, and senders and recipients have no reasonable way to detect this. Most email systems provide ways of using encryption for message content, including attachments, or users can use peer-to-peer solutions like PGP, which will minimize the risk if used properly. Since most email server connections use HTTPS, only the routing information is exposed to potential disclosure via traffic analysis. No existing email systems have strong nonrepudiation capabilities, allowing senders to claim they never received emails or received ones with different content than what was sent.
