Interface Numbering Conventions

Interface numbers used in this manual are examples. In device configuration, use the existing interface numbers on devices.

Security Conventions

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.
Encryption algorithm
Currently, the device uses the following encryption algorithms: DES, 3DES, AES, DSA, RSA, DH, ECDH, HMAC, SHA1, SHA2, PBKDF2, scrypt, and MD5. The encryption algorithm depends on the applicable scenario. Use the recommended encryption algorithm; otherwise, security defense requirements may be not met.
- For the symmetrical encryption algorithm, use AES with the key of 256 bits or more.
- When you need to use an asymmetric cryptography, RSA (2048-bit or longer key) is recommended. In addition, use different key pairs for encryption and signature.
- For the digital signature, RSA (2048-bit or longer key) or DSA (2048-bit or longer key) is recommended.
- For key negotiation, DH (2048-bit or longer key) or ECDH (256-bit or longer key) is recommended.
- For the hash algorithm, use SHA with the key of 256 bits or more.
- For the HMAC algorithm, use HMAC-SHA2.
- DES, 3DES, RSA and AES are reversible encryption algorithm. If protocols are used for interconnection, the locally stored password must be reversible.
- SHA1, SHA2, and MD5 are irreversible encryption algorithm. When configuring a password for local administrator, it is recommended that you use the SHA2 irreversible encryption algorithm.
- To prevent brute force cracking of the user password, the iteration algorithm is added to the password on the basis of salts. The iteration algorithm uses PBKDF2 or scrypt key export algorithm.
- The ECB mode has a poor capability of defending against plaintext playback attacks, so ECB is not recommended for password encryption.
- In SSH2.0, the symmetric cryptography using the CBC mode may undergo the plaintext-recovery attack to cause a data leak. Therefore, the CBC mode is not recommended for SSH2.0.
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.
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.

Declaration

This manual is only a reference for you to configure your devices. The contents in the manual, such as web pages, command line syntax, and command outputs, are based on the device conditions in the lab. The manual provides instructions for general scenarios, but do not cover all usage scenarios of all product models. The contents in the manual may be different from your actual device situations due to the differences in software versions, models, and configuration files. The manual will not list every possible difference. You should configure your devices according to actual situations.
The specifications provided in this manual are tested in lab environment (for example, the tested device has been installed with a certain type of boards or only one protocol is run on the device). Results may differ from the listed specifications when you attempt to obtain the maximum values with multiple functions enabled on the device.
In this document, public IP addresses may be used in feature introduction and configuration examples and are for reference only unless otherwise specified.
In this document, AR series access routers include AR100&AR120&AR150&AR160&AR200&AR1200&AR2200&AR3200&AR3600 Series.
