We would like to give you a few tips here for using passwords:
- Keep a password as secret as possible. Never write down a password. For example, the following are popular but completely unsuitable: Notebooks, wallets and text files in computers. It sounds trivial, but it can't be repeated often enough: don't tell anyone your password. The most secure systems surrender to talkativeness.
- Only transmit passwords in a secure manner. A selected password must be reported to the other side. To do this, select the most secure method possible. Avoid: Non-secure e-mail, letter, or fax. Informing people one-on-one is preferable. The maximum security is achieved when you personally enter the password at both ends.
- Select a secure password. Use random strings of letters and
numbers. Passwords from common language usage are not secure. Special
characters such as '&“?#-*+_:;,!°' make it difficult for potential
attackers to guess your password and increase the security of the password.Note: Capital and small letters are distinguished in the configuration password.
- Never use a password twice. If you use the same password for several purposes, you reduce its security effect. If the other end is not secure, you also endanger all other connections for which you use this password at once.
- Change the password regularly. Passwords should be changed as frequently as possible. This requires effort, however considerably increases the security of the password.
- Change the password immediately if you suspect someone else knows it. If an employee with access to a password leaves the company, it is high time to change this password. A password should also always be changed when there is the slightest suspicion of a leak.
If you comply with these simple rules, you will achieve the highest possible degree of security.
