T 2.55 Uncontrolled use of electronic mail
Uncontrolled use of electronic messages includes the threat that unwarranted
persons can get access to sensitive information or that they may not arrive at
the intended recipient on time.
Examples:
- An incorrect address may be the reason for an electronic message being
sent to an unauthorised recipient
If distribution lists are not maintained in regular terms electronic mail may
be sent to certain recipients, who should have been excluded from the
distribution list.
- An incorrect sending mode can cause problems during the transmission or
receiving of messages. If a file had not been converted into 7-bit ASCII
format by uuencode, it might be converted incorrectly and thus become
unreadable for the recipient During transmission the relaying of messages
may be erased from one of the participating IT systems if the file set is too
large
- Missing or insufficient requirements documents at the recipient’s end may
cause a delay in the processing of a received electronic message.
- Lack of, or insufficient allocation of responsibilities by the responsible
party sending the message, might cause a delay in the assured delivery of
data on schedule.
