Explanation

DTLS is used for delay sensitive applications (voice and video) as its UDP based while TLS is TCP based.

Therefore DTLS offers strongest throughput performance. The throughput of DTLS at the time of AnyConnect connection can be expected to have processing performance close to VPN throughput.

To connect Cisco Secure Workload to external orchestrators at a client site where incoming connections are not allowed, a reverse tunnel must be used. A reverse tunnel initiates the connection from the inside of the client ' s network out to the external orchestrator, thereby bypassing restrictions on incoming connections and enabling secure communication.

To block certain URLs based on the “Chat and Instant Messaging” category, the network administrator should select a reputation score of 5. A reputation score is a numerical value that indicates the likelihood of a URL being malicious or unwanted. The lower the score, the higher the risk. A score of 5 means that the URL is suspicious or potentially harmful, and should be blocked or inspected12. A score of 3 means that the URL is unknown or unverified, and may be allowed or blocked depending on the policy settings12. A score of 10 means that the URL is trustworthy or benign, and should be allowed12. A score of 1 means that the URL is malicious or high-risk, and should be blocked12. Therefore, a score of 5 is the most appropriate to block the “Chat and Instant Messaging” category, which may contain unwanted or problematic websites. References:

 The RADIUS CoA feature supports five IETF attributes as defined in RFC 5176. These are:

Event-Timestamp: This attribute indicates the time when the CoA request was generated by the server.

State: This attribute contains a value that is copied from the Access-Accept message that authorized the session.

Session-Timeout: This attribute specifies the maximum number of seconds of service provided to the user before termination of the session or prompt.

Idle-Timeout: This attribute specifies the maximum number of consecutive seconds of idle connection allowed to the user before termination of the session or prompt.

Filter-Id: This attribute identifies the filter list to be applied to the user session.

The RADIUS CoA feature also supports vendor-specific attributes (VSAs) that are defined by Cisco or other vendors. These VSAs can be used to perform additional actions such as port shutdown, port bounce, or security and password accounting. References :=

 Microsegmentation is a method of securing multi cloud data centers using granular segmentation rules for the individual workload or application, reducing the risk of an attacker moving from one compromised workload or application to another1. Microsegmentation with Cisco ACI enables you to automatically assign endpoints to logical security zones called endpoint groups (EPGs). These EPGs are based on various network-based or virtual machine (VM)-based attributes2. Microsegmentation is also referred to as application segmentation or east-west segmentation in a multicloud data center1. References: 1: What Is Micro-Segmentation? - Cisco 2: Microsegmentation with Cisco ACI

 The management port on Cisco FMC is used to establish a secure connection with the managed Cisco FTD devices. If the default management port (8305) conflicts with other communications on the network, it must be changed on both the Cisco FMC and the Cisco FTD devices. This cannot be done automatically by the Cisco FMC, as it would lose connectivity with the devices. Therefore, the administrator must manually change the management port on the Cisco FMC and all the managed Cisco FTD devices using the command line interface (CLI). The steps to change the management port are as follows:

Log into the CLI of the Cisco FMC and the Cisco FTD devices using a console connection or SSH.

Enter the configure network {ipv4 | ipv6} manual ip_address netmask data-interfaces command to change the management port on the Cisco FMC. For example, configure network ipv4 manual 10.10.10.10 255.255.255.0 data-interfaces changes the management port to 10.10.10.10/24.

Enter the configure network {ipv4 | ipv6} manual ip_address netmask gateway management-only command to change the management port on the Cisco FTD devices. For example, configure network ipv4 manual 10.10.10.11 255.255.255.0 10.10.10.10 management-only changes the management port to 10.10.10.11/24 and sets the gateway to the Cisco FMC’s management port.

Save the configuration and restart the Cisco FMC and the Cisco FTD devices.

Verify the connectivity between the Cisco FMC and the Cisco FTD devices using the show managers command on the Cisco FTD devices and the show devices command on the Cisco FMC.
