 EPP solutions solely focus on the perimeter of the network, which is the boundary between the internal and external networks. The perimeter is where most of the endpoints, such as laptops, desktops, mobile devices, and IoT devices, are located and connected to the network. EPP solutions aim to prevent, detect, and remediate security threats on these endpoints by using technologies such as antivirus, data encryption, and data loss prevention. EPP solutions rely on signatures and other indicators of intrusion by known threats to block malicious activity and malware on the endpoints12.

EDR solutions do not focus on the perimeter, but rather on the entire network, including the core and the East-West gateways. The core is the central part of the network that connects different segments and provides high-speed data transmission. The East-West gateways are the points of communication between different segments within the network, such as between different data centers or cloud environments. EDR solutions provide continuous and comprehensive visibility into endpoint activities across the network by using threat hunting tools for behavior-based endpoint threat detection. EDR solutions monitor and record endpoint data, detect anomalies and malicious behavior, and respond to threats that EPP and other security tools did not catch. EDR solutions also enable security teams to proactively investigate and contain incidents by using incident data search, alert triage, threat validation, and malicious activity blocking134.

Contextual awareness is the ability to collect and analyze information about the network environment, such as users, devices, applications, threats, and vulnerabilities, and use it to enhance security policies and actions. Cisco Firepower is a network security device that supports contextual awareness by providing real-time visibility into network traffic and activity, security intelligence from Cisco Talos and other sources, and advanced threat protection with Cisco AMP and sandboxing. Cisco Firepower can also leverage Cisco pxGrid to share contextual data with other security solutions, such as SIEM and TD platforms, to enable faster and more accurate threat detection and response123 References := 1: Cisco Firepower NGIPS Data Sheet - Cisco 2: Cisco Identity Services Engine with Integrated Security Information and Event Management and Threat Defense Platforms At-a-Glance - Cisco 3: A Visibility-Driven Approach to Next-Generation Firewalls

Cisco FTDv is a virtual appliance that combines the features of Cisco ASA and Cisco Firepower NGIPS. It provides stateful firewall, IPS, URL filtering, malware protection, and other advanced security functions. Cisco ASAv is a virtual appliance that only provides stateful firewall and VPN features. It does not support URL filtering or other Firepower functions. Therefore, Cisco FTDv provides more features than ASAv, especially for next-generation firewall capabilities. References :=

 A security application that notifies a controller within a software-defined network architecture about a specific security threat is using a northbound API. A northbound API is an interface that enables communication between the SDN controller and the applications or management systems that use the network services1. A security application can use a northbound API to send alerts, requests, or commands to the SDN controller, which can then take appropriate actions on the network devices or policies2. For example, a security application can use a northbound API to inform the SDN controller about a malicious traffic pattern, and the SDN controller can then block or redirect the traffic using a southbound API3.
