Micro-segmentation secures applications by expressly allowing particular application traffic and, by default, denying all other traffic. Micro-segmentation is the foundation for implementing a zero-trust security model for application workloads in the data center and cloud. Cisco Tetration is an application workload security platform designed to secure your compute instances across any infrastructure and any cloud. To achieve this, it uses behavior and attribute-driven microsegmentation policy generation and enforcement. It enables trusted access through automated, exhaustive context from various systems to automatically adapt security policies. To generate accurate microsegmentation policy, Cisco Tetration performs application dependency mapping to discover the relationships between different application tiers and infrastructure services. In addition, the platform supports “what-if” policy analysis using real-time data or historical data to assist in the validation and risk assessment of policy application pre-enforcement to ensure ongoing application availability. The normalized microsegmentation policy can be enforced through the application workload itself for a consistent approach to workload microsegmentation across any environment, including virtualized, bare-metal, and container workloads running in any public cloud or any data center. Once the microsegmentation policy is enforced, Cisco Tetration continues to monitor for compliance deviations, ensuring the segmentation policy is up to date as the application behavior change.

A DoS (Denial of Service) attack is a type of cyberattack that aims to disrupt the normal functioning of a server, service, or network by overwhelming it with a large amount of traffic or requests. A DoS attack typically uses a single computer or device to launch the attack, sending TCP (Transmission Control Protocol) or UDP (User Datagram Protocol) packets to the target server. TCP and UDP are two common protocols used to send data over the internet. TCP packets require a connection to be established between the sender and the receiver, and ensure that the data is delivered reliably and in order. UDP packets do not require a connection, and do not guarantee the delivery or order of the data. Both TCP and UDP packets can be used to flood a server with requests, consuming its resources and bandwidth, and preventing legitimate users from accessing the service.
A DDoS (Distributed Denial of Service) attack is a type of DoS attack that uses multiple computers or devices to launch the attack, creating a large network of attackers that can generate more traffic or requests than a single source. A DDoS attack often involves a botnet, which is a network of compromised computers or devices that are controlled by a malicious actor, usually through malware or hacking. The botnet can send TCP or UDP packets to the target server from different locations and IP addresses, making it harder to trace and block the attack. A DDoS attack can also target multiple servers or services that are distributed over a LAN (Local Area Network), such as a web hosting service or a cloud computing platform, affecting the availability and performance of the entire network.
The main difference between a DoS attack and a DDoS attack is the number and diversity of the sources that are involved in the attack. A DoS attack comes from a single source, while a DDoS attack comes from multiple sources. This makes a DDoS attack more powerful, faster, and harder to stop than a DoS attack.

The Southbound API is used to communicate between Controllers and network devices.

Northbound and southbound APIs are two types of interfaces that enable communication between different layers of the SDN architecture. Northbound APIs relay information between the controller and the applications or policy engines, while southbound APIs relay information between the controller and the network devices.
Northbound APIs allow applications to request network services or resources from the controller, such as bandwidth, latency, security, or routing. The controller then translates these requests into network configurations and applies them to the network devices via the southbound APIs. Northbound APIs typically use RESTful API methods such as GET, POST, and DELETE to communicate with the controller.
Southbound APIs allow the controller to program the network devices to perform forwarding and other functions. The controller can use different protocols or standards to communicate with the network devices, depending on their capabilities and vendor-specific features. Some common examples of southbound APIs are CLI, SNMP, RESTCONF, NETCONF, OpenFlow, and OpFlex.

Other features are dependent on SSL Decryption functionality, which requires the Cisco Umbrella root certificate. Having the SSL Decryption feature improves:
Custom URL Blocking-Required to block the HTTPS version of a URL.
…
Umbrella’s Block Page and Block Page Bypass features present an SSL certificate to browsers that make connections to HTTPS sites. This SSL certificate matches the requested site but will be signed by the Cisco Umbrella certificate authority (CA). If the CA is not trusted by your browser, an error page may be displayed.
Typical errors include “The security certificate presented by this website was not issued by a trusted certificate authority” (Internet Explorer), “The site’s security certificate is not trusted!” (Google Chrome) or “This Connection is Untrusted” (Mozilla Firefox). Although the error page is expected, the message displayed can be confusing and you may wish to prevent it from appearing.
To avoid these error pages, install the Cisco Umbrella root certificate into your browser or the browsers of your users-if you’re a network admin.

Cisco DNA Center APIs are RESTful APIs that allow you to automate and operate your network at scale, using Python scripts or other tools. They are not Cisco proprietary, as they follow the OpenAPI specification and can be accessed by any client that supports HTTP requests. They do not require Postman, although Postman is a useful tool to test and explore the API endpoints. They can quickly provision new devices by applying predefined templates and workflows, and they can view the overall health of the network by retrieving metrics and alerts from various sources.

When the Cisco Secure Firewall downloads threat intelligence updates from Cisco Talos, it is engaged in
“consumption.” This term refers to the process of receiving and utilizing threat intelligence data to enhance security measures. Cisco Talos provides comprehensive threat intelligence that Cisco Secure Firewall consumes to update its threat detection and prevention capabilities.
