JUSX-DM-000023 - The Juniper SRX Services Gateway must automatically generate a log event when accounts are enabled.

Information

Once an attacker establishes initial access to a system, the attacker often attempts to create a persistent method of reestablishing access. One way to accomplish this is for the attacker to simply enable a new or disabled account. Notification of account enabling is one method for mitigating this risk. A comprehensive account management process will ensure an audit trail which documents the creation of application user accounts and notifies administrators and Information System Security Officers (ISSO). Such a process greatly reduces the risk that accounts will be surreptitiously created and provides logging that can be used for forensic purposes.

Accounts can be disabled by configuring the account with the build-in login class 'unauthorized'. When the command is reissued with a different login class, the account is enabled.

Solution

The following commands configure the device to immediately display a message to any currently logged on administrator's console when changes are made to the configuration.

[edit]
set system syslog host <IP-syslog-server> any any
set system syslog file account-actions change-log any any
