To collect full metadata information about the traffic going through their AWS cloud services, the organization needs to send VPC Flow Logs to Cisco Stealthwatch Cloud and configure Cisco Stealthwatch Cloud to ingest AWS information. VPC Flow Logs is a feature that enables the organization to capture information about the IP traffic going to and from network interfaces in their VPC. Flow log data can be published to Amazon CloudWatch Logs, Amazon S3, or Amazon Kinesis Data Firehose1. Cisco Stealthwatch Cloud is a SaaS-based network and cloud security solution that provides behavioral analytics across the network to help the organization improve threat detection and achieve a stronger security posture2. By sending VPC Flow Logs to Cisco Stealthwatch Cloud, the organization can leverage the rich network flow metadata to perform various types of flow analysis, such as troubleshooting connectivity issues, monitoring the traffic patterns, detecting anomalous or malicious activity, and verifying compliance3. To send VPC Flow Logs to Cisco Stealthwatch Cloud, the organization needs to create a flow log for their VPC, subnet, or network interface, and specify Cisco Stealthwatch Cloud as the destination4. To configure Cisco Stealthwatch Cloud to ingest AWS information, the organization needs to add their AWS account as a data source in the Cisco Stealthwatch Cloud portal, and grant the necessary permissions for Cisco Stealthwatch Cloud to access their VPC Flow Logs5. By doing so, the organization can view and analyze the flow log data in the Cisco Stealthwatch Cloud dashboard, and receive valuable security alerts and insights based on the network behavior6.

Cisco Umbrella is a cloud-delivered security service that provides DNS-layer security, secure web gateway, firewall, cloud access security broker, and threat intelligence functions. It helps improve security visibility, detect compromised systems, and protect your users on and off the network by stopping threats over any port or protocol before they reach your network or endpoints1. One of the benefits of using Cisco Umbrella is that it can block threats before they launch, reducing response times, and delivering safe, secure internet with Umbrella's cloud tools2. By intercepting DNS requests and applying security policies, Umbrella can prevent malicious connections from being established, and mitigate attacks before the application connection occurs3. This can also reduce bandwidth costs and improve performance by filtering out unwanted traffic1.

Cisco Umbrella allows you to create custom destination lists that contain specific domains or IP addresses that you want to allow or block. You can then apply these destination lists to your policies to override the default behavior of Umbrella. For example, if you want to block specific addresses using Cisco Umbrella, you can create a destination list with those addresses and set the action to block. Then, you can assign this destination list to the policy that you want to modify. This way, any request to those addresses will be blocked by Umbrella, regardless of the content category or application settings12 References := 1: Manage Policies - Umbrella User Guide 2: Understanding Destination lists supported entries and error messages - Cisco Umbrella

ExplanationSNMP polling can often be in the order of 5-10 minutes, CLIs are unstructured and prone to change which can often break scripts.The traditional use of the pull model, where the client requests data from the network does not scale when what you want is near real-time data.Moreover, in some use cases, there is the need to be notified only when some data changes, like interfaces status, protocol neighbors change etc.Model-Driven Telemetry is a new approach for network monitoring in which data is streamed from network devices continuously using a push model and provides near real-time access to operational statistics.
