A serverless application is one that does not require the developer to manage the underlying infrastructure or servers. Instead, the application code is executed by a cloud provider in response to events or triggers, such as HTTP requests, database changes, or messages. The cloud provider automatically provisions, scales, and manages the resources needed to run the code, and charges only for the time and resources consumed by the execution. A serverless application runs from an ephemeral, event-triggered, and stateless container that is fully managed by a cloud provider. This means that the container is created on demand when an event occurs, and is destroyed when the execution is completed. The container does not store any persistent state or data, and is isolated from other containers. The cloud provider handles the load balancing, fault tolerance, security, and monitoring of the container. A serverless application can leverage various cloud services, such as databases, storage, messaging, analytics, and machine learning, to perform complex tasks and functionalities. Serverless computing is a cloud-native development model that enables developers to focus on the business logic and deliver faster and more scalable applications. References:

Explanation

Spero analysis is a feature of Cisco AMP for Networks that examines structural characteristics such as metadata and header information in executable files. After generating a Spero signature based on this information, if the file is an eligible executable file, the device submits it to the Spero heuristic engine in the AMP cloud for analysis1. Spero analysis can detect malware based on the file’s structure and behavior, without requiring a full file upload2. Spero analysis is different from dynamic analysis, sandbox analysis, and malware analysis, which are other features of Cisco AMP for Networks that perform different types of file inspection and analysis3. References: 1: How to configure Firepower AMP to not upload files to … - Cisco Community 2: File Policies - Network Direction 3: Cisco AMP for Networks - Cisco

 Retrospective security is a feature of Cisco AMP that enables continuous analysis and alerting of files and network activity, even after the initial point of inspection. It allows an engineer to look back in time and trace the processes, file activities, and communications of an endpoint that was infected by malware. This helps to understand the full extent of an infection, establish root causes, and perform remediation. Retrospective security is different from endpoint isolation, advanced search, and advanced investigation, which are other features of Cisco AMP that provide different capabilities. Endpoint isolation allows an engineer to isolate an endpoint from the network to prevent further spread of malware. Advanced search allows an engineer to query the AMP cloud database for information about files, endpoints, events, and trajectories. Advanced investigation allows an engineer to perform deep analysis of files and endpoints using Cisco Secure Malware Analytics (formerly Threat Grid). References :=
