Obtaining information by phone or email is a common way of getting to your data – or your money. The caller will put pressure on you (“if you do not give me your password, your access will be blocked”) and thereby try to manipulate you. Consistently refer callers who wish to ask questions about federal affairs to your communications unit and inform your superior about such calls or emails.
Such requests can also be made by email. In this case, delete quickly with the key combination Shift+Delete!
