Security Conventions
l Password setting
– When configuring a password, the cipher text is recommended. To ensure device
security, change the password periodically.
– When you configure a password in plain text that starts and ends with %@%@, @
%@%, %#%#, or %^%# (the password can be decrypted by the device), the
password is displayed in the same manner as the configured one in the
configuration file. Do not use this setting.
– When you configure a password in cipher text, different features cannot use the
same cipher-text password. For example, the cipher-text password set for the AAA
feature cannot be used for other features.
l Encryption algorithm
Currently, the device uses the following encryption algorithms: 3DES, AES, RSA,
SHA1, SHA2, and MD5. 3DES, RSA and AES are reversible, while SHA1, SHA2, and
MD5 are irreversible. The encryption algorithms DES/3DES/RSA (RSA-1024 or
lower)/MD5 (in digital signature scenarios and password encryption)/SHA1 (in digital
signature scenarios) have a low security, which may bring security risks. If protocols
allowed, using more secure encryption algorithms, such as AES/RSA (RSA-2048 or
higher)/SHA2/HMAC-SHA2, is recommended. The encryption algorithm depends on
actual networking. The irreversible encryption algorithm must be used for the
administrator password, SHA2 is recommended.
l Personal data
Some personal data may be obtained or used during operation or fault location of your
purchased products, services, features, so you have an obligation to make privacy
policies and take measures according to the applicable law of the country to protect
personal data.
l The terms mirrored port, port mirroring, traffic mirroring, and mirroring in this manual
are mentioned only to describe the product's function of communication error or failure
detection, and do not involve collection or processing of any personal information or
communication data of users.
