CoA Messages are sent on two different udp ports depending on the platform. Cisco standardizes on UDP port 1700, while the actual RFC calls out using UDP port 3799.

The telemetry information consists of three types of data:+ Flow information: This information contains details about endpoints, protocols, ports, when the flow started, how long the flow was active, etc.+ Interpacket variation: This information captures any interpacket variations within the flow. Examples include variation in Time To Live (TTL), IP and TCP flags, payload length, etc+ Context details: Context information is derived outside the packet header. It includes details about variation in buffer utilization, packet drops within a flow, association with tunnel endpoints, etc.

Cisco Email Security Appliance (ESA) protects the email infrastructure and employees who use email at work by filtering unsolicited and malicious email before it reaches the user. Cisco ESA easily integrates into existing email infrastructures with a high degree of flexibility. It does this by acting as a Mail Transfer Agent (MTA) within the email-delivery chain. Another name for an MTA is a mail relay.

Cisco Stealthwatch Cloud is a cloud-delivered and SaaS-based solution that provides visibility and threat detection across the AWS network. It does not require any software agents to be installed on the AWS instances, and it relies on AWS VPC flow logs to collect network traffic metadata. Cisco Stealthwatch Cloud analyzes the flow logs using machine learning and behavioral modeling to detect anomalies and threats, such as data exfiltration, lateral movement, reconnaissance, and compromised instances. Cisco Stealthwatch Cloud also provides contextual information and actionable alerts to help users respond to incidents and remediate issues.Cisco Umbrella is a cloud-delivered and SaaS-based solution that provides DNS-layer security and web filtering for internet traffic. It does not provide visibility and threat detection for internal AWS network traffic, and it requires software agents to be installed on the endpoints or network devices to enforce policies and redirect DNS requests.NetFlow collectors are devices or software applications that collect and analyze NetFlow records, which are generated by network devices to capture information about IP traffic flows. NetFlow collectors can provide visibility and threat detection for network traffic, but they are not cloud-delivered or SaaS-based solutions. They also require NetFlow exporters to be configured on the network devices, which may not be supported by AWS.Cisco Cloudlock is a cloud-delivered and SaaS-based solution that provides cloud security posture management (CSPM) and cloud access security broker (CASB) capabilities for cloud applications and environments. It does not provide visibility and threat detection for AWS network traffic, and it does not rely on AWS VPC flow logs. It focuses on protecting cloud data, users, and configurations from misconfigurations, compliance violations, and malicious activities.Reference:=Cisco Stealthwatch Cloud for AWSCisco UmbrellaNetFlow[Cisco Cloudlock]

Each rule also has an action, which determines whether you monitor, trust, block, or allow matching traffic.Note: With action ''trust'', Firepower does not do any more inspection on the traffic. There will be no intrusion protection and also no file-policy on this traffic.

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.Reference:1:Intelligent Proxy - Cisco Umbrella2:Cisco Umbrella SIG Advantage - Cisco Umbrella3:[SSL Decryption - Cisco Umbrella]4:[IP Layer Enforcement - Cisco Umbrella]5:[Advanced Malware Protection - Cisco Umbrella]

The application blocking list is an outbreak control method that allows the administrator to block certain files from executing on the endpoints based on their SHA values. This can prevent malware from running on the endpoints and causing damage. The other options are not outbreak control methods, but rather different features of AMP for endpoints. Device flow correlation is a network analysis feature that monitors connections and detects malicious activity. Simple detections and advanced custom detections are custom rules that can be created by the administrator to detect and block files based on signatures or other criteria.Reference:Configure Windows Policy in AMP for Endpoints - CiscoPrevent, Detect and Respond with Cisco AMP for Endpoints

Cisco ISE is the security solution that is used for posture assessment of the endpoints in a BYOD solution. Posture assessment allows Cisco ISE to inspect the security health of the endpoints, such as their operating system, software applications, network settings, and security software. Cisco ISE can then enforce posture policies based on the compliance status of the endpoints and grant or deny them access to the network resources. Cisco ISE supports different types of posture agents, such as AnyConnect, AnyConnect Stealth, and Temporal Agent, to monitor and remediate the endpoints. Cisco ISE also supports agentless posture for devices that cannot run an agent, such as printers, cameras, and IoT devices. Cisco ISE integrates with various third-party vendors to provide posture assessment for different endpoint platforms, such as Windows, Mac, Linux, Android, and iOS.Reference:=Some possible references are:Cisco Identity Services Engine Administrator Guide, Release 3.0 - ComplianceChapter 15.
