Vulnerability discussion

Upon gaining access to a network device, an attacker will often first attempt to create a persistent method of reestablishing access. One way to accomplish this is to create a new account. Notification of account creation helps to mitigate this risk. Auditing account creation provides the necessary reconciliation that account management procedures are being followed. Without this audit trail, personnel without the proper authorization may gain access to critical network nodes.

Check content

Review the router configuration to determine if it audits account creation. This requirement can be met by ensuring that configuration changes are logged as shown in the following example: system { syslog { file LOG_FILE { change-log info; } } } Note: The parameter “any” can be in place of “change-log” as this will log everything. Also, a syslog server can be configured in addition to or in lieu of logging to a file as shown in the example below. system { syslog { host 10.1.58.2 { any info; } file LOG_FILE { change-log info; } console { any error; } } } If account creation is not audited, this is a finding.

Fix text

Configure the router to audit the creation of accounts. This requirement can be met by ensuring that configuration changes are logged as shown in the following example: [edit system] set syslog file LOG_FILE change-log info Note: The parameter “any” can be in place of “change-log” as this will log everything. Also, a syslog server can be configured in addition to or in lieu of logging to a file as shown in the example below. set syslog host 10.1.58.2 any info

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
