Vulnerability discussion

Associating event outcome with detected events in the log provides a means of investigating an attack or suspected attack.The logs should identify what servers, destination addresses, applications, or databases were potentially attacked by logging communications traffic between the target and the attacker. All commands that were entered by the attacker (such as account creations, changes in permissions, files accessed, etc.) during the session should also be logged.Packet captures of attack traffic can be used by forensic tools for analysis for example, to determine if an alert is real or a false alarm or for forensics for threat intelligence.

Check content

Go to Objects >> Security Profiles >> Antivirus View the configured Antivirus Profiles. If the Packet Capture check box is not checked, this is a finding. Go to Objects >> Security Profiles >> Anti-Spyware View the configured Anti-Spyware Profiles. If the "Packet Capture" field does not show extended-capture, this is a finding. Go to Objects >> Security Profiles >> Vulnerability Protection View the configured Vulnerability Protection Profiles. If the "Packet Capture" field does not show extended-capture, this is a finding. Go to Policies >> Security Review each of the configured security policies in turn. For any Security Policy that affects traffic between Zones (interzone), view the "Profile" column. If the "Profile" column does not display the Antivirus Profile, Anti-Spyware, and Vulnerability Protection symbols, this is a finding.

Fix text

In the "Anti-Spyware Rule" window, in the "Packet Capture" field, select "extended-capture". Select "OK". Select "OK" again. Configure a Vulnerability Protection Profile to capture detected malicious traffic. Go to Objects >> Security Profiles >> Vulnerability Protection Select the name of a configured Vulnerability Protection Profile or select "Add" to create a new one. In the "Vulnerability Protection Profile" window, complete the required fields. In the "Rules" tab, select the name of a configured Vulnerability Protection Rule or select "Add" to create a new one. In the "Vulnerability Protection Rule" window, in the "Packet Capture" field, select "extended-capture". Select "OK". Select "OK" again. Use the Antivirus Profile, Anti-Spyware Profile, and Vulnerability Protection Profile in a Security Policy. Go to Policies >> Security Select an existing policy rule or select "Add" to create a new one. In the "Actions tab in the Profile Setting section: In the "Profile Type" field, select "Profiles". The window will change to display the different categories of Profiles. In the "Antivirus" field, select the configured Antivirus Profile. In the "Anti-Spyware" field, select the configured Anti-Spyware Profile. In the "Vulnerability Protection" field, select the configured Vulnerability Protection Profile. Select "OK".

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.
