Avamar: Come gestire le impostazioni di sicurezza delle sessioni dalla CLI

Controlli preliminari:

• Arrestare tutti i backup, la replica e verificare che non sia in esecuzione alcuna manutenzione (checkpoint/hfscheck/garbage collection).
• Verificare che sia disponibile un checkpoint valido su Avamar.

Panoramica:

Lo script seguente viene installato in ogni griglia Avamar e viene utilizzato per gestire le impostazioni di sicurezza della sessione:

enable_secure_config.sh

Per visualizzare le impostazioni correnti di Session Security:

enable_secure_config.sh --showconfig

Output di esempio che mostra la sicurezza della sessione disabilitata:

Current Session Security Settings
----------------------------------
"encrypt_server_authenticate"                           ="false"
"secure_agent_feature_on"                               ="false"
"session_ticket_feature_on"                             ="false"
"secure_agents_mode"                                    ="unsecure_only"
"secure_st_mode"                                        ="unsecure_only"
"secure_dd_feature_on"                                  ="false"
"verifypeer"                                            ="no"

Client and Server Communication set to Default (Workflow Re-Run) mode with No Authentication.
Client Agent and Management Server Communication set to unsecure_only mode.
Secure Data Domain Feature is Disabled. 

Output di esempio che mostra la sicurezza della sessione mista-singola:

Current Session Security Settings
----------------------------------
"encrypt_server_authenticate"                           ="true"
"secure_agent_feature_on"                               ="true"
"session_ticket_feature_on"                             ="true"
"secure_agents_mode"                                    ="mixed"
"secure_st_mode"                                        ="mixed"
"secure_dd_feature_on"                                  ="true"
"verifypeer"                                            ="no"

Client and Server Communication set to Mixed mode with One-Way/Single Authentication.
Client Agent and Management Server Communication set to mixed mode.
Secure Data Domain Feature is Enabled.

Output di esempio che mostra la sicurezza della sessione singola autenticata:

Current Session Security Settings
----------------------------------
"encrypt_server_authenticate"                           ="true"
"secure_agent_feature_on"                               ="true"
"session_ticket_feature_on"                             ="true"
"secure_agents_mode"                                    ="secure_only"
"secure_st_mode"                                        ="secure_only"
"secure_dd_feature_on"                                  ="true"
"verifypeer"                                            ="no"

Client and Server Communication set to Authenticated mode with One-Way/Single Authentication.
Client Agent and Management Server Communication set to secure_only mode.
Secure Data Domain Feature is Enabled.

Output di esempio che mostra la sicurezza della sessione doppia autenticata:

Current Session Security Settings
----------------------------------
"encrypt_server_authenticate"                           ="true"
"secure_agent_feature_on"                               ="true"
"session_ticket_feature_on"                             ="true"
"secure_agents_mode"                                    ="secure_only"
"secure_st_mode"                                        ="secure_only"
"secure_dd_feature_on"                                  ="true"
"verifypeer"                                            ="yes"

Client and Server Communication set to Authenticated mode with Two-Way/Dual Authentication.
Client Agent and Management Server Communication set to secure_only mode.
Secure Data Domain Feature is Enabled.
