 TACACS+ is a protocol that provides authentication, authorization, and accounting (AAA) services for network devices. Unlike RADIUS, which only supports authorization at the user level, TACACS+ supports authorization at the command level. This means that TACACS+ can verify the permissions of the network administrator for every command that is entered, and allow or deny access accordingly. This provides more granular and secure control over network resources and operations. EAPOL, SSH, and RADIUS are not protocols that can provide command-level authorization for AAA. References :=

Cisco Umbrella allows you to create custom destination lists that contain specific domains or IP addresses that you want to allow or block. You can then apply these destination lists to your policies to override the default behavior of Umbrella. For example, if you want to block specific addresses using Cisco Umbrella, you can create a destination list with those addresses and set the action to block. Then, you can assign this destination list to the policy that you want to modify. This way, any request to those addresses will be blocked by Umbrella, regardless of the content category or application settings12 References := 1: Manage Policies - Umbrella User Guide 2: Understanding Destination lists supported entries and error messages - Cisco Umbrella

The purpose of a Denial-of-Service (DoS) attack is to disrupt the normal operation of a targeted system, server, or network by overwhelming it with a flood of internet traffic. This is achieved by utilizing multiple compromised computer systems as sources of attack traffic. The overwhelming amount of traffic can cause the targeted system to slow down significantly or even crash and become unavailable to legitimate users, thereby denying service to intended users.
