8.1
Tips for the proper treatment of keys and pass-
phrases
By observing a few vital rules on the treatment of keys you can significantly
increase the security of encryption techniques.
Keep your keys as secret as possible.
Never write down a key. Popular but completely unsuitable are, for exam-
ple: Notebooks, wallets and text files on the computer. Do not pass on a
key unless it is absolutely necessary.
Choose a random key.
Use long random strings that combine letters and numbers (at least 32 to
a maximum of 63 characters). Keys that are normal words are not secure.
If you suspect anything, change the key immediately.
When an employee with access to a key leaves the company, then it is
high time to change the wireless LAN key. Even if there is the slightest sus-
picion of a leak, renew the key.
8.2
Security settings Wizard
Access to the configuration of a device allows access to more than just critical
information (e. g. Internet password). Far more critical is that settings for
security functions (e.g. the firewall) can be altered. Unauthorized access is not
just a risk for the device itself, but for the entire network.
Your LANCOM offers password-protected access to its configuration. This is
activated during the initial basic configuration simply by entering a password.
If the wrong password is entered a certain number of times, the device auto-
matically blocks access to the configuration for a fixed period. You can modify
the critical number of attempts and also the duration of the lock. By default,
the device locks for five minutes after five incorrect entries of the password.
