Vulnerability discussion

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 modify an existing account. Notification of account modification is one method for mitigating this risk. A comprehensive account management process will ensure an audit trail which documents the modification of device administrator accounts and notifies administrators and Information System Security Officers (ISSO). Such a process greatly reduces the risk that accounts will be surreptitiously modified and provides logging that can be used for forensic purposes.The network device must generate the alert. Notification may be done by a management server.

Check content

Verify that RiOS uses automated mechanisms to alert security personnel to threats identified by authoritative sources. Navigate to the device Management Console Navigate to Configure >> System Settings >> SNMP Basic Verify that Host Servers are defined in the section "Trap Receivers" If there are no Host Servers defined in "Trap Receivers", this is a finding.

Fix text

Configure RiOS to use automated mechanisms to alert security personnel to threats identified by authoritative sources. Navigate to the device Management Console Navigate to Configure >> System Settings >> SNMP Basic Click "Add a New Trap Receiver" Set "Receiver IP Address" to the address of the trap receiver Set "Destination Port:" to the port that the Trap Receiver is listening on Set "Receiver Type:" to v3 Set "Remote User:" to the user name on the Trap Receiver Set "Authentication:" to Set "Authentication Protocol:" to SHA SHA Key: Set "Security Level:" to Auth/Priv Set "Privacy Protocol:" to "AES" Set "Privacy:" to Select "same as Authentication Key" Set "Enable Receiver" Click "Add" Navigate to the top of the web page and click "Save" to save these settings permanently.

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.
