The Cisco DNA Center API provides the ability to program and monitor networks from somewhere other than the DNAC GUI. The API is a set of RESTful web services that allow users to interact with Cisco DNA Center programmatically. The API can be used to automate tasks, integrate with third-party applications, or create custom applications. The API exposes the same functionality as the DNAC GUI, such as design, provision, policy, assurance, and platform1. The API also provides documentation, examples, and testing tools for each API call1. References :=

ETHOS is one of the many detection engines that AMP uses to continuously protect you from malware. It is only available in the public cloud, as it requires a large amount of data and processing power to operate. ETHOS uses machine learning to analyze the behavior and characteristics of files and determine their maliciousness. It can detect both known and unknown threats, as well as polymorphic and metamorphic malware that can change their appearance or code. ETHOS is part of the AMP cloud’s dynamic analysis capabilities, which also include SPERO and Threat Grid12.

The private cloud instance of AMP does not have ETHOS, as it is meant to be an on-premises, self-contained solution that satisfies stringent privacy requirements. The private cloud instance also does not have SPERO or Threat Grid, unless they are deployed separately as additional appliances. The private cloud instance relies on the TETRA detection engine, which is a signature-based engine that can identify known malware. TETRA is updated regularly with new signatures from the AMP cloud, but it cannot detect unknown or zero-day threats as effectively as ETHOS34.

Therefore, the capability that is exclusive to the AMP public cloud instance as compared to the private cloud instance is the ETHOS detection engine. References: 1: Cisco Advanced Malware Protection Private Cloud Appliance Data Sheet 2: What is AMP Private Cloud 3: Deploy Cisco AMP Private Cloud on Cisco HyperFlex Systems 4: AMP Private Cloud vs Public Cloud Dashboard different

ExplanationDynamic ARP inspection (DAI) is a security feature that validates ARP packets in a network. It intercepts, logs, and discards ARP packets with invalid IP-to-MAC address bindings. This capability protects the network from certain man-in-the-middle attacks. After enabling DAI, all ports become untrusted ports.

To enable malware file scanning for the Secure Internet Gateway (SIG), you need to enable Intelligent Proxy, which is a feature of Cisco Umbrella that provides selective proxying of web requests based on the risk level of the domain1. Intelligent Proxy allows SIG to inspect the content of potentially malicious web requests and block or allow them based on the configured policies2. Intelligent Proxy also enables SSL decryption, which is necessary to scan encrypted web traffic for malware3. Enabling IP Layer enforcement, activating the Advanced Malware Protection license, and activating SSL decryption are not required prerequisites to enable malware file scanning for the SIG, although they may provide additional security benefits45. References: 1: Intelligent Proxy - Cisco Umbrella 2: Cisco Umbrella SIG Advantage - Cisco Umbrella 3: [SSL Decryption - Cisco Umbrella] 4: [IP Layer Enforcement - Cisco Umbrella] 5: [Advanced Malware Protection - Cisco Umbrella]
