1 New Features and Enhancements

The following topics describe new features and enhancements for Oracle® Communications Security Shield releases.

23.0.0.0.0 - February 2023

The following information describes the new content and behavior delivered in the latest Oracle® Communications Security Shield (OCSS ) release.

The following table describes the new features and enhancements in the OCSS 23.0.0.0.0 release.

Features Description
Enhanced User Alerts Notifications

The 23.0.0.0.0 release enhances notifications about threatening call activity by adding electronic messaging directly to subscribers by way of email, Slack, and PagerDuty services.

The new Subscriptions sub-tab on the OCSS Notifications tab displays information about the subscribers configured to receive notifications when OCSS detects threat conditions. The Subscriptions sub-tab also displays the Create Subscription button to launch the configuration dialog, as well as filters for search operations.

See "The Notifications Subscriptions Tab" in the OCSS User's Guide.

Additional Insights to Call Scores

The 23.0.0.0.0 release adds more information about call scores to the analytical reports by providing greater explanation of the reason codes and call behaviors.

To help you see the additional information, Oracle added the new Call Insights attribute to the Total Calls Table canvas. Call Insights provides the following information:
  • Application-to-Person (A2P)—Reason codes specific to application-to-person messaging. For example, verification codes, appointment reminders, One Time Passcodes, verification messages, or other calls sent to a user.
  • Person-to-Person (P2P)—Reason codes specific to human-to-human calls.
  • Number Type—The line type or phone type information.
  • Activity—Reason codes related to the amount of activity OCSS observed for the number, compared to what is expected for a good user. For example, the number of communications transactions to or from the number, the quantity of unique numbers communicated with, and the number of accounts communicated with.

A privileged administrator can add the Call Insights attribute to an existing canvas.

See "Policy Results Statistics Attributes" and "Policy Results Threats Attributes" in the OCSS User's Guide.

22.2.0.0.0 - November 2022

The following information describes the new content and behavior delivered in the latest Oracle® Communications Security Shield (OCSS ) release.

The following table describes the new features and enhancements in the OCSS 22.2.0.0.0 release.

Features Description
Enhanced Analytics Reports

Oracle significantly enhanced the usability and focus of the OCSS analytics functionality. With one click of the new Analytics Reports button on the Dashboard, OCSS displays a single, new default Project (a collection of canvases) displaying commonly requested visualizations that provides real-time, interactive viewing capabilities.

From the default Project, you can create customized Projects to which you add canvases and visualizations. You can export, duplicate, move, and save Projects. As before, you can export canvases, data, and images from the visualizations on the canvases.

See the "Call Traffic Analytics" Appendix in the OCSS User's Guide.

Access Control List Enhancement Oracle enhanced the Access Control List functionality to allow you to create policies based on calling number and called number. For example, you might want block or redirect specific calling numbers for specific destinations, such as company executives or to block harassing callers from reaching specific agents.

Access Control Lists contain rules that you create for Calling and Called numbers. When you create a rule, you can specify the Calling Number, the Called Number, or both. You can add multiple numbers to a rule and you can specify ranges of numbers, the call direction, and the enforcement action.

See "Add an Access Control List" and "Add a Rule to an Access Control List" in the OCSS User's Guide.

Manage Nonconforming Calling Numbers

When a calling number does not conform to E.164 phone number conventions, even after normalization, OCSS provides you with ways to specify call treatment and reports threats from nonconforming calling numbers to the Threats by Count tile on the Dashboard. Nonconforming call management applies to both the Standard and Premium editions.

See "How OCSS Manages Nonconforming Calling Numbers" in the OCSS User's Guide.

Enhanced Access Control List Processing

OCSS processes Access Control Lists (ACL) independently from regular threat processing and an action taken due to an ACL match overrides decisions made due to threat analysis. Due to the override, previous versions of OCSS omitted threat processing of calls for which an ACL match was determined. As of the 22.2.0.0.0 release, calls that match an ACL rule will also be fully analyzed for threat status. The threat status will be reported as part of the OCSS Dashboard statistics and will be available in the analytics environment. OCSS reports both the ACL status and the threat status of the call, although the ACL decision still overrides.

22.1.0.0.0 - August 2022

The following information describes the new content and behavior delivered in the latest Oracle® Communications Security Shield ( OCSS ) release.

The following table describes the new features and enhancements in the OCSS 22.1.0.0.0 release.

Features Description
Inbound Call Labeling When an inbound call goes through OCSS, OCSS adds the P-OCSS-Call-Info header to the SIP INVITE. The information in the header can help you make more informed decisions about your network. For example, you might want to route certain types of calls to a particular queue, or require extra validation, or restrict the caller's options.

See "Inbound Call Labeling" in the OCSSC User's Guide.

Notifications Tab The 22.1.0.0.0 release adds the Notifications tab to the Web GUI. OCSS displays notifications when certain call-related conditions occur that might need your attention, for example, elevated risky call types and other kinds of calls from bad actors. On the Notifications tab, privileged users can view a watch list of notifications and configure notifications settings.

See "The Notifications Tab" in the OCSSC User's Guide.

Enhanced Dashboard Update Behavior Beginning with the 22.1.0.0.0 release, OCSS updates the Dashboard upon call initiation and other events rather than solely upon call termination. OCSS uses any available information upon call initiation and can update the Dashboard with new information as the call progresses. OCSS no longer restricts the display to reporting only about terminated calls. The result is better synchronization with the analytics reports, which report on calls when they arrive.
Emergency Number Treatment Description When the Session Border Controller (SBC) receives a call with a calling number containing an emergency number (currently limited to 100, 108, 111, 112, 181, 911, and 999,) the SBC (SPL) will not invoke a query to OCSS. Emergency calls will proceed as normal.

22.0.0.0.0 - May 2022

The following information describes the new content and behavior delivered in the latest Oracle® Communications Security Shield ( OCSS ) release.

The following table describes the new features in the OCSS 22.0.0.0.0 release.

Features Description
Support for Session Border Controller-to-Cloud High Availability You can configure the Session Border Controller (SBC) to distribute Oracle® Communications Security Shield (OCSS) traffic to as many as three Cloud Communication Service (CCS) instances to provide continuity of service if one or more CCS instances stops responding or loses connectivity to the cloud.

See "Support for SBC to Cloud High Availability" in the Installation and Maintenance Guide.

Subscription Suspension and Termination Process If you do not renew your Oracle® Communications Security Shield (OCSS) subscription before the scheduled end date, Oracle provides a phased continuation process that allows you more time to renew before hard termination. See "Subscription Usage" and "Subscription Suspension and Termination Phases" in the User's Guide.
Support for Inbound Phone Number Normalization The Oracle® Communications Security Shield (OCSS) uses the E.164 format for call validation from the Session Border Controller. Because OCSS may be used in environments that use number formats other than E.164, OCSS provides a way to normalize non-E.164 number format conventions to the E.164 convention. See "Inbound Phone Number Normalization" in the User's Guide.
Support for Creating Customized Analytics Reports As a privileged user, you can create custom Oracle® Communications Security Shield (OCSS) analytics reports to display the type of data you want to see in the format you want. You can create custom OCSS analytics reports from call elements, filters, calculations, and formats that you choose.

See "Create Customized Analytics Reports" in the User's Guide.

21.3.0.0.0 - February 2022

The following information describes the new content and behavior delivered in the latest Oracle® Communications Security Shield ( OCSS ) release.

The following table describes the new features in the OCSS 21.3.0.0.0 release.

Features Description
OCI Identity Domain Support The 21.3.0.0.0 release supports the Oracle Cloud Infrastructure (OCI) Identity Domain for new and existing customers. Oracle will migrate existing customers seamlessly without service impacts in the coming months.

See "OCI Identity Domain: What OCI Identity Domain Customers Need to Know" and "OCI Identity Domain: What Oracle IDCS Customers Need to Know" in the OCSS Installation and Maintenance Guide.

Updates to Reputation Score call classifications The 21.3.0.0.0 release updates the classifications shown in the Reputation Score Classification configuration and in the Dashboard tiles for Autonomous Threat Protection, Call Classifications and Top Targeted Enforcement Points.
  • Reputation Score Classification—In the Reputation Score Classification configuration, "Unclassified" is renamed "Acceptable" and "Regular" is renamed "Good." See "Reputation Score Classification" in the User's Guide.
  • Autonomous Threat Protection—The Autonomous Threat Protection Dashboard tile no longer counts or reports "Acceptable" (formerly "Unclassified") calls as detected threats. See "Autonomous Threat Protection" in the User's Guide.
  • Call Classification—The Call Classification Dashboard tile consolidates the former pair of graphs into one graph. To customize the display, you can click the items in the legend to show or hide their data according to what you want to see in the graph. See "Call Classifications" in the User's Guide.
  • Top Targeted Enforcement Points—The Top Targeted Enforcement Points Dashboard tile no longer counts or reports "Acceptable" (formerly "Unclassified") calls as detected threats. See "Top Targeted Enforcement Points" in the User's Guide.

See the Session Border Controller Platform Preparation and Installation Guide if you use Oracle Communications Session Border Controllers. If not, see the documentation for the device that you use.

Disable Mid-Call Updates The 21C release adds a way to enable or disable mid-call updates by entering or omitting the WAN certificate and private key paths in the Cloud Communication Service (CCS) activate.pl script.

See "Enable or Disable Mid-Call Updates" in the OCSS Installation and Maintenance Guide.

Updates to the CCS Configuration page on the Settings tab. The 21C release adds the OCSS FQDN and IDCS FQDN elements to the information provided on the CCS Configuration page on the Settings tab.

See "Cloud Communication Service Configuration Settings" in the OCSS User's Guide.

Block calls that do not pass STIR validation. The 21C release adds the Block Inbound Calls that Fail STIR Validation parameter to the General Settings configuration on the Autonomous Threat Protection settings tab. When enabled, OCSS overrides the reputation score enforcement action configuration for a call that does not pass STIR verification and blocks the call.

See "Autonomous Threat Protection Settings" and "Edit General Settings" in the OCSS User's Guide.

Session Plug-in Language (SPL) Show Commands The 21C release adds a list of SPL show commands that you can access through the Acme Command Line Interface (ACLI).

See "OCSS Sow Commands" in the OCSS Installation and Maintenance Guide.

The following functions that were present but not operational in the preceding release are now operational. The 21C release supports the following operations:
  • Validating outbound calls

  • Modifying FROM in the presentation number

See "The Outbound Call Validation Tab" chapter in the OCSS User's Guide.

Call Type Classifications update The 21C release updates the Call Type Classifications for low-value, no-value, and other unwanted incoming calls for Premium Subscribers. Go to the Settings tab and click the Call Type Classifications link to see the classification types, descriptions, and configurable enforcement actions. Go to the Dashboard tab to see the Threats by Count tile, which displays the number of threats received per classification type per period of time.

21B Update 1 - August 2021

The following information describes the new content and behavior delivered in the Oracle® Communications Security Shield ( OCSS ) 21B Update 1.

The following table describes the new features in the OCSS 21B Update 1.

Features Description
Support for the Standard Subscription

21B Update 1 adds support for the Standard OCSS subscription.

See "OCSS Service Plans Comparison" in the User's Guide.

Mitigate Call Flooding

OCSS can detect and mitigate call flooding by monitoring the inbound call rate per phone number and applying configurable enforcement actions when the rate exceeds the threshold you set. OCSS can detect call flooding caused by Telephony Denial of Service, Traffic Pumping, and Toll Fraud. See "Call Flooding Mitigation" in the User's Guide.

Create a List of Outbound Enterprise Calling Numbers

The OCSS GUI displays the Outbound Call Validation tab and allows you to create a list of outbound enterprise phone numbers with configurable attributes.

Note:

OCSS does not support applying the functionality of call validation and attribute use to call traffic at this time.

See "The Outbound Call Validation Tab" chapter in the User's Guide.

Number Lookup Tab The Number Lookup tab provides a way to search for a phone number across all of your OCSS phone number lists. The resulting display shows every list and states whether or not the number is on the list. The search results show the settings for the number per type of list. See "The OCSS Number Lookup Tab" chapter in the User's Guide.
Block Calls with "Anonymous" in FROM

OCSS adds support for blocking inbound calls that contain Anonymous in one or both of the FROM and P-Asserted Identity headers and one or both of the user name and host name parts. For example, suppose a fraudster removes the user identity and inserts anonymous@, private@, restricted@, user@example1.edu, null@ or other such entries in the FROM or the P-Asserted Identity (PAI) headers. The result makes the caller identification anonymous and unverifiable. You can block such calls.

See "Edit General Settings" in the User's Guide.

Support for Multi-Factor Authentication To make the Oracle® Communications Security Shield (OCSS) more secure, you can enable multi-factor authentication for user log on. See "Secure Access to OCSS with Multi-Factor Authentication" in the Installation and Maintenance Guide.

21B Release - June 2021

The following information describes the new content and behavior delivered in the Oracle® Communications Security Shield ( OCSS ) 21B release.

New Features

The following table describes the new features in the OCSS 21B release.
Features Description
New user groups to support least privileged access

The 21B release adds a set of user groups to help you manage access to OCSS according to the least amount of privilege needed. The privileges of each group determine which tabs, links, and information the user can see and which actions the user can perform.

See "User Groups and Privileges" in the Installation and Maintenance Guide.

Policy Decision Engine Relocation to the Oracle Cloud Infrastructure

The 21B release relocates the Policy Decision Engine (PDE) from an on-premises deployment to the Oracle Cloud Infrastructure (OCI). In the OCI, Oracle manages and maintains the PDE. Customers no longer need to install the PDE on premises.

Oracle recommends that customers using a release prior to 21B, where the PDE is installed on-premises, uninstall the PDE to reduce the OCSS footprint on local resources.

Auto Refresh Rate for Dashboard Tiles

The 21B release adds the Auto Refresh control to the Dashboard for setting the rate at which the tiles refresh. You can use the default refresh rate or choose one from the menu that displays when you click Auto Refresh.

See "The Dashboard Tab" in the User's Guide.

Change in the SPL Plug-in Download Method

The 21B release packages the SPL Plug-in with the Cloud Communication Service download.

See "Download the OCSS Software" in the Installation and Maintenance Guide.

Call Rate Limiting for a TDoS Attack

The 21B release adds call rate limiting as an enforcement method when the OCSS detects a Telephony Denial of Service (TDoS) attack. You can specify the maximum rate of calls that you want the OCSS to allow as a way of mitigating a TDoS attack. When incoming calls exceed the specified call rate, the OCSS drops calls randomly such that the rate of calls allowed to traverse the SBC matches the configured Call Attempt Rate Limit that you set for the Network-wide TDoS and Overload Protection parameter in the Threat Vector Thresholds configuration.

The 21B release removes call blocking as an available enforcement action for a TDoS attack. The remaining values are Allow and Rate Limit.

See "Threat Vector Thresholds" in the User's Guide.

Behavioral Changes

The following information describes behavioral changes to the OCSS service.

Objects Description
Threat Vector Thresholds parameters
  • The Threat Vector Thresholds tab no longer displays the Toll-Free Traffic Pumping parameter because the 21B release does not support Toll-Free Traffic Pumping as a fraudulent call volume mitigation.
  • The 21B release renames the TDoS (Telephony Denial of Service) parameter as Network-Wide TDoS and Overload Protection.
  • The available enforcement actions for the Network-Wide TDoS and Overload Protection parameter are Allow and Rate Limit. The 21B release does not support the former Block enforcement action.
Toll-Free Traffic Pumping The 21B release does not support the Toll-Free Traffic Pumping parameter for fraudulent call volume mitigation.

20B Update 3 - February 2021

The following information describes the new features and enhancements delivered in the Oracle® Communications Security Shield ( OCSS ) 20B - February 2021 update.

New Features

The following table describes the new features in the OCSS 20D - February 2021 update.
Features Description
Activity Logging

OCSS adds a way to view user activity logs through the new Activity Log tab to help with troubleshooting and security audits. You can see activity such as configuration changes to access control lists, threshold parameters, and on-premises software components for periods of up to ninety days.

The activity log supports search operations with various filters to help you find the logs you want to see, for example, Date Range, User, Category, and Action.

The logs display the following information: Timestamp, User, Device, Category, Object ID, Action, and Activity Details.

No-value and low-value call detection for Premium Subscribers

To help Premium Subscribers get a more accurate understanding of the risks to their call centers and to help them to continuously improve responses to risky and unwanted calls, OCSS replaced the former rather general Risky calls category with an expanded set of no-value and low-value Call Type Classifications.

The no-value and low-value Call Type Classifications provided for Premium subscribers include Scam, Other Fraud, Robocall, Telemarketing, and Invalid-Spoofing Number. For each of the new Call Type Classifications, you can set one of the following actions that you want OCSS to apply to these calls through the new Call Type Classifications dialog on the Settings page: Block, Redirect, and Continue. By applying actions to the call classifications, you can use OCSS to shield your customer service agents and other employees from calls that waste time, harm productivity, and cause unwanted expenses.

Premium subscribers can see data about Call Type Classifications activity on the OCSS Dashboard in the Threats by Count tile and in the Autonomous Threat Protection tile because the OCSS reputation scoring operations will also use these classifications when determining call reputation scores.

Simulate a Call Lookup On the Access Control Lists tab, the All Numbers List page adds the Simulate Look up button. Use Simulate Lookup when you want to know how the Policy Decision Engine will enforce access control on a particular phone number on your list. OCSS can process the phone number through a call simulator and return the result, which shows the call direction, the enforcement action that the Policy Decision Engine will apply, and the name of the list that contains the phone number. In this way, you can see whether or not the enforcement action is what you want and you can adjust it, if needed..

20B Update 2 - October 2020

The following information describes the new features and enhancements delivered in the Oracle® Communications Security Shield ( OCSS ) 20B - October 2020 update.

New Features

The following table describes the new features in the OCSS 20B - October 2020 update.
Features Description
Access Control Lists The 20B - October 2020 update replaces the previous list management with the new Access Control Lists tab and extends the functionality by allowing you to create, delete, and rename your own lists. In prior versions, the access control lists hard-coded the call direction and action for all numbers on a list. The new list management allows you to apply any direction or action to any number on any list. You can create up to ten Access Control lists.

In the left pane of the Access Control Lists tab, the system displays the All Numbers List, which is a view of all of the phone numbers from all of your lists combined. The All Numbers view can make searching easier when you do not recall which list contains the number you want to find.

From the view list, you can perform a simulated phone number lookup to see how the OCSS Policy Decision Engine will enforce access control on a specified phone number if it were used in a real call.

See the "Access Control Lists" chapter in the User's Guide.

Enhancements

The following table describes the new enhancements in the OCSS 20B - October 2020 update.
