| Configuring the Security Features | 201Parameter Description Configuration MethodVerify Status Cache Time InIdle Configure the cachedauthentication status time of theWPP20/CTP20 when not in a call.Note: It is configurable onlywhen the accessories joincollaboration confirmationfeature is enabled. Note: thevalid value is from 1 to 15 andthe default value is 5 minutes.If you change this parameter, thesystem will reboot to make thechange take effect.Web user interfaceConfiguring the Auto Logout TimeThe system will log out of the web user interface automatically after being inactive for a period of time. Youneed to re-enter the login credentials to login. You can change the auto logo time.Procedure1. On your web user interface, go to Setting > General > General Information >ReLogOffTime(1-1000min).2. Configure and save the following settings:Parameter Description Configuration MethodReLogOffTime (1-1000min) Specify the inactive time(minutes) before the system logsout of the web user interfaceautomatically.Default: 5 minutes.Web user interfaceTransport Layer Security (TLS)Transport Layer Protocol (TLS) is a commonly used protocol for ensuring communications privacy andmanaging the security of the message transmission. When secured by the TLS protocol, the device cantransmit the data and communicate safely.The TLS protocol includes two protocol groups: the TLS handshake protocol and the TLS record protocol.The TLS handshake protocol allows the server and the client to authenticate with each other beforenegotiating about the data, the encryption algorithms and the encrypted keys. The TLS Record Protocolcompletes the actual data transmission and ensures the data integrity and confidentiality. The TLS protocoluses an asymmetric encryption algorithm to exchange keys, a symmetric encryption algorithm to ensuredata confidentiality, and the MAC algorithms to ensure data integrity.• Supported Cipher Suites• TLS Transport Protocol• Managing the Trusted Certificates List• Managing the Server Certificates
