Security Conventions
- Password setting
- To ensure device security, use ciphertext when configuring a password and change the password periodically.
- The switch considers all passwords starting and ending with %^%#, %#%#, %@%@ or @%@% as ciphertext and attempts to decrypt them. If you configure a plaintext password that starts and ends with %^%#, %#%#, %@%@ or @%@%, the switch decrypts it and records it into the configuration file (plaintext passwords are not recorded for the sake of security). Therefore, do not set a password starting and ending with %^%#, %#%#, %@%@ or @%@%.
- When you configure passwords in ciphertext, different features must use different ciphertext passwords. For example, the ciphertext password set for the AAA feature cannot be used for other features.
- Encryption algorithms
The switch currently supports the 3DES, AES, RSA, SHA1, SHA2, and MD5. 3DES, RSA, and AES are reversible, whereas SHA1, SHA2, and MD5 are irreversible. Using the encryption algorithms DES , 3DES, RSA (RSA-1024 or lower), MD5 (in digital signature scenarios and password encryption), or SHA1 (in digital signature scenarios) is a security risk. If protocols allow, use more secure encryption algorithms, such as AES, RSA (RSA-2048 or higher), SHA2, or HMAC-SHA2.
An irreversible encryption algorithm must be used for the administrator password. SHA2 is recommended for this purpose.
- Personal data
Some personal data (such as MAC or IP addresses of terminals) 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.
- Mirroring
The terms mirrored port, port mirroring, traffic mirroring, and mirroring in this document 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.
