SV-77185r1_rule The Palo Alto Networks security platform must send an alert to, at a minimum, the ISSO and ISSM when threats identified by authoritative sources (e.g., IAVMs or CTOs) are detected.

Vulnerability discussion

Without an alert, security personnel may be unaware of an impending failure of the audit capability, and the ability to perform forensic analysis and detect rate-based and other anomalies will be impeded.Alerts may be transmitted, for example, telephonically, by electronic mail messages, or by text messaging. The IDPS must either send the alert to a management console that is actively monitored by authorized personnel or use a messaging capability to send the alert directly to designated personnel.Each Security Policy created in response to an IAVM or CTO must log violations of that particular Security Policy. For each violation of a security policy, an alert to, at a minimum, the ISSO and ISSM, must be sent.

Check content

Ask the Administrator how the ISSO and ISSM are receiving alerts (E-mail, SNMP Trap, or Syslog). View the configured Server Profile; if there is no Server Profile for the method explained, this is a finding. View the Log Forwarding Profiles; this is under Objects >> Log Forwarding. Determine which Server Profile is associated with each Log Forwarding Profile. View the Security Policies that are used to enforce policies issued by authoritative sources. Go to Policies >> Security Select the name of the security policy to view it. In the "Actions" tab, in the "Log Setting" section, view the Log Forwarding Profile. If there is no Log Forwarding Profile, this is a finding.

Fix text

Configure a Server Profile for use with Log Forwarding Profile(s); If email is used, the ISSO and ISSM must be recipients. To create an email server profile: Go to Device >> Server Profiles >> Email Select "Add". In the Email Server Profile, enter the name of the profile. Select "Add". In the "Servers" tab, enter the required information: In the "Name" field, enter the name of the Email server. In the "Email Display Name" field, enter the name shown in the "From" field of the email. In the "From" field, enter the From email address. In the "To" field, enter the email address of the recipient. In the "Additional Recipient" field, enter the email address of another recipient. You can only add one additional recipient. To add multiple recipients, add the email address of a distribution list. In the "Gateway" field, enter the IP address or host name of the Simple Mail Transport Protocol (SMTP) server used to send the email. Select "OK". Configure a Log Forwarding Profile; this is under Objects >> Log Forwarding. Go to Policies >> Security Select "Add" to create a new security policy or select the name of the security policy to edit it. Configure the specific parameters of the policy by completing the required information in the fields of each tab. In the "Actions" tab, select the Log forwarding profile and select "Log at Session End". "Log at Session Start" may be selected under specific circumstances, but "Log at Session End" is preferred. Commit changes by selecting "Commit" in the upper-right corner of the screen. Select "OK" when the confirmation dialog appears.
