It is a Synapse workspace SKU that's associated with the Virtual Network managed by Azure Synapse. Use Microsoft Defender for Cloud Adaptive Network Hardening to recommend network security group configurations that limit ports and source IPs based with the reference to external network traffic rules.Īzure Synapse Analytics provides Managed Virtual Network Workspace. Any system that might incur higher risk for the organization should be isolated within its own virtual network and sufficiently secured with a network security group (NSG) and/or Azure Firewall. Ensure that all Azure virtual networks follow an enterprise segmentation principle that aligns with the business risks. Guidance: When you deploy Azure Synapse Workspace resources, create or use an existing virtual network. NS-1: Implement security for internal traffic Network Securityįor more information, see the Azure Security Benchmark: Network Security. To see how Synapse Analytics Workspace completely maps to the Azure Security Benchmark, see the full Synapse Analytics Workspace security baseline mapping file. This is quite helpful when trying to identify when a malicious external IP address was first seen in your environment.Controls not applicable to Synapse Analytics Workspace, and those for which the global guidance is recommended verbatim, have been excluded. This “first seen” information is reported even if the first event aged out due to the Log Analytics retention period. The IP entity page also shows when an IP address has first been recorded in an alert or in a set of specific common data sources. Let us know which data sources you most prefer, so that we know what to onboard next. IP-to-host mappings are currently generated from Azure Monitor heartbeat data. The first seen / last seen information enables you to infer when the IP address was assigned to which machine. We also provide a summary of all IP-to-host mappings on each IP entity page. We take this a step further by enabling you to search for hosts using IP-to-host mappings. Like the host and account entities, you can search for individual IP addresses using the Entity Analytics search experience. It compares remote session endpoints to IP Indicators of Compromises (IoCs) provided by Microsoft and by any threat intelligence source for which there is an enabled data connector.īy clicking on “See all connections” you can drill into the details in Log Analytics, so that you can review the data yourself and bookmark important connections. The IP page also makes discovering connections to malicious endpoints easy. The IP page summarizes this information from Azure Monitor, Microsoft Defender for Endpoints (MDE), CommonSecurityLog and other data sources. Understanding which endpoints an IP address has been connecting to is a key task in investigating IP related security incidents. Remote connections and threat indicator data It will soon be available via REST API for security investigation scenarios to Azure Sentinel customers. This service combines data from Microsoft solutions with 3 rd party vendors and partners. We provide geolocation enrichment data from the Microsoft Threat Intelligence service. Geolocation is often used to assess the security relevance of an IP address. This page provides contextual information and insights like geolocation information, threat indicator data, network session data and IP-to-host mappings. The IP page aggregates information from multiple Microsoft and 3rd party data sources. Like the host and account pages, the IP page helps analysts quickly triage and investigate security incidents. Now in preview, the IP entity page is the latest addition to Azure Sentinel's User and Entity Behavior Analytics capabilities.
