    Updates to Existing Behavior

    Feature with Behavior Change
    Descripion
    Alerts on Prisma Cloud
    To reduce noise from alerts for accounts that are not actively monitored using Prisma Cloud, when you add a cloud account on Prisma Cloud and then disable it, you can no longer view existing alerts associated with the disabled account on
    Alerts
    Overview
     on Prisma Cloud.
    Previously, on disabling an account, the alert status—Open, Snoozed, Dismissed, or Resolved—was retained to indicate the last known state and the
    Alerts
    Overview
     count included these alerts.

    New Policy and Policy Updates

    New Policies and Policy Updates
    New Policies
    Azure app services remote debugging is enabled
    Identifies Azure App Services that have remote debugging enabled, which opens up inbound ports on App Services and increases security risk.
    config from cloud.resource where cloud.type = 'azure' AND api.name = 'azure-app-service' AND json.rule = config.remoteDebuggingEnabled is true
    Azure virtual machine boot diagnostics disabled
    Identifies Azure Virtual Machines with boot diagnostics disabled. Boot diagnostics capture screenshots and console output at the virtual machine startup, and this helps with troubleshooting the virtual machine if it enters a non-bootable state.
    config from cloud.resource where cloud.type = 'azure' AND api.name = 'azure-vm-list' AND json.rule = ['properties.diagnosticsProfile'].bootDiagnostics.enabled is false
    Azure virtual machine scale sets boot diagnostics disabled
    Identifies Azure Virtual Machine scale sets with boot diagnostics disabled. When boot diagnostics is enabled for the virtual machine, it captures screenshot and console output during the virtual machine startup and helps with troubleshooting the virtual machine if it enters a non-bootable state.
    config from cloud.resource where cloud.type = 'azure' AND api.name = 'azure-virtual-machine-scale-set' AND json.rule = properties.virtualMachineProfile.diagnosticsProfile.bootDiagnostics.enabled is false
    Policy Updates—RQL and Metadata
    Alibaba Cloud MFA is disabled for RAM user
    The RQL has been updated to check for MFA device value to report disabled MFA users.
    config from cloud.resource where cloud.type = 'alibaba_cloud' AND api.name = 'alibaba-cloud-ram-user' AND json.rule = 'MFADevice is empty'
    Impact
    : Previous alerts will get resolved as Policy_Updated and new alerts will be generated using the revised query.
    Alibaba Cloud Security group overly permissive to all traffic
    The Policy Name and Description have been updated. The policy checks for inbound rules that allow traffic from (0.0.0.0/0) any IP address.
    Impact
    : This change does not affect alerts.
    Azure storage account logging for queues is disabled
    Updated RQL
    —The updated RQL is 
    config from cloud.resource where cloud.type = 'azure' AND api.name = 'azure-storage-account-list' AND json.rule = 'sku.tier equals Standard and loggingProperties.queue exists and (loggingProperties.queue.readEnabled is false or loggingProperties.queue.writeEnabled is false or loggingProperties.queue.deleteEnabled is false)'
    The RQL has been updated to properly identify Azure Blob Storage accounts.
    Impact
    : This RQL fix resolves previously opened alerts and marks them as Policy_Updated.
    Azure storage account logging for tables is disabled
    Updated RQL
    —The updated RQL is 
    config from cloud.resource where cloud.type = 'azure' AND api.name = 'azure-storage-account-list' AND json.rule = 'sku.tier equals Standard and (loggingProperties.table.readEnabled is false or loggingProperties.table.writeEnabled is false or loggingProperties.table.deleteEnabled is false)'
    The RQL has been updated to properly identify Azure Blob Storage accounts.
    Impact
    : This RQL fix resolves previously opened alerts and marks them as Policy_Updated.
    Policy Updates—Recommendation
    AWS Elastic File System (EFS) with encryption for data at rest is disabled
    The recommendation instructions in the policy is updated to replace RedShift with AWS Elastic File System (EFS).

    Rest API Updates

    Change
    Description
    Update
     Rate limiting on List Alert APIs
    Prisma Cloud will now enforce rate limiting on the following APIs:
    • GET /v2/alert
    • POST /v2/alert
    The limit is one request per second for a client session. Excess of the limit will result in an HTTP 429 error code.
    Impact
    —While most clients will not see any effect, if you're using automation, please plan to insert delay and retry logic to work with the new rate limits.

    New Features Introduced in 20.12.1

    New Features

    Feature
    Description
    Machine Learning Classification Improvements for Unusual User Activity / UEBA Policies
    For better detection of anomalies, the machine learning model is being updated on Prisma Cloud. These changes are transparent to you.
    ueba-anomaly-policies.png
    For
    Excessive login failures
    , the detection window has been reduced from 1 hour to 15 minutes and the default threshold is set to 5 failed login events. Also, the model building thresholds have been reduced from 7 days and 4 events to 1 day and just 1 event to help you detect incidents sooner.
    For generating alerts on
    Account hijacking attempts
    , the minimum distance between the two locations has to be at least 1000 miles within a 2-hour period.
    For
    Unusual user activity
    , the unknown location alert will be generated only if the new location is at least 160 miles away, instead of 120 miles from any of the known locations in the model.
    Malware Scan Status in Data Inventory
    If you have enabled the Prisma Cloud Data Security subscription, you can review the malware scan status on the Data Inventory table on
    Inventory
    Data
    .
    Two new columns display the time stamp of when Prisma Cloud received the verdict from the WildFire service, and the scan status to indicate whether the scan is in progress, failed, file type is not supported or too large, or confirmation if the object is malware or benign.
    Read-Only Permission Group Update
    Prisma Cloud administrators who are assigned to the read-only permission group can now save filters on the
    Asset Inventory
     and
    Compliance
     page.

    New Policy and Policy Updates

    New Policies and Policy Updates
    Policy Updates—RQL and Metadata
    AWS Security Groups policies
    These policies are renamed to remove the word 'internet' from the name and to leverage nested rules for RQL optimization:
    • AWS Security Groups allow internet traffic from internet to FTP-Data port (20)
    • AWS Security Groups allow internet traffic from internet to FTP port (21)
    • AWS Security Groups allow internet traffic to SSH port (22)
    • AWS Security Groups allow internet traffic from internet to Telnet port (23)
    • AWS Security Groups allow internet traffic from internet to SMTP port (25)
    • AWS Security Groups allow internet traffic from internet to DNS port (53)
    • AWS Security Groups allow internet traffic from internet to Windows RPC port (135)
    • AWS Security Groups allow internet traffic from internet to NetBIOS port (137)
    • AWS Security Groups allow internet traffic from internet to NetBIOS port (138)
    • AWS Security Groups allow internet traffic from internet to CIFS port (445)
    • AWS Security Groups allow internet traffic from internet to SQLServer port (1433)
    • AWS Security Groups allow internet traffic from internet to SQLServer port (1434)
    • AWS Security Groups allow internet traffic from internet to MYSQL port (3306)
    • AWS Security Groups allow internet traffic from internet to RDP port (3389)
    • AWS Security Groups allow internet traffic from internet to MSQL port (4333)

    • AWS Security Groups allow internet traffic from internet to VNC Listener port (5500)
    • AWS Security Groups allow internet traffic from internet to VNC Server port (5900)
    Reason
    :
    • The word
      Internet
      is removed from the policy name and description.
    • The RQL grammar will be updated to use a nested array.
    Impact
    —There is no change in the number of alerts generated against these policies.
    Azure Network Security Group policies
    The following policies are mapped to the Azure CIS compliance benchmark, and the severity is being updated from Medium to High.
    • Azure Network Security Group having Inbound rule overly permissive to all traffic on TCP protocol
    • Azure Network Security Group having Inbound rule overly permissive to all traffic on UDP protocol
    • Azure Network Security Group having Inbound rule overly permissive to all traffic on any protocol
    Reason
    —The severity was updated because these policies check for overly permissive Azure network security group inbound rules from all open ports for TCP, UDP or any protocol.
    Impact
    — The compliance report may include additional alerts because three additional policies are mapped to Azure CIS compliance benchmark.
    GCP Kubernetes Engine Clusters have HTTP load balancing disabled
    Updated RQL
    — The updated RQL is 
    config from cloud.resource where cloud.type = 'gcp' AND api.name = 'gcloud-container-describe-clusters' AND json.rule = 'addonsConfig.httpLoadBalancing.disabled equals true'
    Impact
    —Open alerts that are false positives will be resolved.
    Custom Policy Modification
    When you modify the RQL in a custom policy, you cannot change the
    cloud.type
     and the
    api.name
    , in the existing policy.
    To revise either of these attributes, you must create a new custom policy and disable or delete the existing policy.

    REST API Updates

    Change
    Description
    Infrastructure-As-Code (IaC) Scan API Version 2
    A new IaC Scan API that returns scan result details in OASIS Static Analysis Results Interchange Format (SARIF) is available.
