These joiners can either run on a dedicated AMP appliance or be installed as a service on a Cisco Next Generation IPS (NGIPS), on an ASA that includes the FirePOWER service, or on a Next Generation Firewall (NGFW) called a Firepower Threat Defense (FTD) appliance.Figure 2-14 Communication between AMP Connector, FMC and CloudNote that unless a policy is configured to send the file into the Threat Grid for further analysis, the AMP Connector will only send the SHA-256 hash of the file.AMP also has retrospective analysis capabilities. The AMP appliance for the network can retain past data. When the file's alignmentalignment changes, AMP performs a historical analysis of what happened to track the event/infection. With the assistance of the AMP for endpoint hostsAMP's assistance, retrospective analysis can contact that host and fix the bad file, even if the file was previously allowed.2.2.10 Web Security Appliances To keep the unit's network environment safe from Web-based security threats, security administrators need to deploy a variety of heirloom :Sin conventional tools and mitigation techniques used to block known malicious sites. Today, people can download malware from a variety of infected legitimate sites (for example, social media sites, advertisements on news and corporate sites, and gaming sites). Cisco has introduced a variety of tools and mechanisms (e.g., Cisco Web Security Appliance [WSA], Cisco Security Management Appliance [SMA], and Cisco Cloud Web Security [CWS]) to help customers address such security threats. These solutions not only can detect, block, and continuously monitor malware, but also support backtracking alerting capabilities.CiscoWSA uses cloud-based intelligence from Cisco to help protect unit networks before, during, and after an attack. This "lifecycle" is called the attack period (attack134 Chapter 2 Network Security Appliances and Cloud Services
