1.1 Change Guardian SaaS Deployment

As a part of Change Guardian deployment in SaaS environment, the following features have been introduced:

  • Deployment of Regional and Master server: A regional server is deployed to collect event data from the regions that are on premises and a master server is deployed to provide a consolidated view of event data across all the regions.

  • Script based Deployment of Infrastructure and Change Guardian Server: Users can configure communication between the Change Guardian Server and Connectors using scripts.

  • Regional Server Load Balancing: Regional server load balancing enables the even distribution of the incoming event data. It processes and creates a balance within the flow of data between the deployed regional servers.

  • Backup and Disaster Recovery: Users can backup the event data on cloud and restore the data during a system failure.

For more information, see Change Guardian in SaaS.

1.2 Federated View of Events

  • Change Guardian has provisioned a federated view of the event data from regional servers to the master server.

  • The users can view all the events collectively from a particular region by grouping the regional servers.

1.3 Forwarding Event Data to Cloud

Users can send event data from the Forwarder to the cloud layer by configuring integrators at the Forwarder level.

1.4 Performance Improvement Tweaks

The performance of Change Guardian has been enhanced and improvised to process additional number of agents and increased inflow of data.

1.5 Forwarder Communication through Proxy

Change Guardian enables the flow of data through proxy servers which act as intermediaries between the client applications and other servers.

1.6 Export Import Tool

Export import tool enables the users to source policy configuration from a single server to other single or multiple servers.

1.7 Agent Cache Increase

The event caching for Windows and UNIX agents has been increased to 10 MB. When the communication between agent and forwarder is disrupted, the agent can store events up to the cache size.

1.8 Configuring Communication through Scripts

Users can configure Connectors and Integrators using scripts to enable communication between the Agent, Forwarder, and the Cloud Layer.

1.9 AWS Instance Alarm

In an AWS console, when any of the regional or master server instances cross the threshold of a predefined parameter limit, the AWS users are alerted.

1.10 OpenSSL Fix

This release resolves an issue where a vulnerability in OpenSSL certificate parsing leaves systems open to denial-of-service attacks.(CVE-2022-0778)
