The Talos IP and Domain Reputation Center is the world’s most comprehensive real-time threat detection network. It collects and analyzes data from millions of web requests, emails, malware samples, open-source data sets, endpoint intelligence, and network intrusions. It assigns a reputation score to IP addresses and domains based on their observed malicious activity and behavior. The reputation score can range from -10 (very malicious) to +10 (very benign). The reputation score can be used to block or allow traffic, or to trigger further inspection or analysis. The Talos IP and Domain Reputation Center allows you to track the reputation of IP addresses for email and web traffic, as well as to look up the category, volume, and history of any IP address or domain. You can also submit feedback or request a change of reputation for any IP address or domain. References

In a Cisco Secure Workload implementation, telemetry data can be generated from IPFIX (Internet Protocol Flow Information Export) records using NetFlow connectors and Cisco Secure Workload itself. NetFlow provides insights into network traffic flow and volume, while Cisco Secure Workload uses this data for visibility, segmentation, and security analytics within the data center.

Workload security models refer to the ways of protecting applications, services, and capabilities that run on a cloud resource. There are different types of cloud deployment models, such as public, private, hybrid, and multicloud, and different types of cloud service models, such as IaaS, PaaS, and SaaS. However, these are not workload security models, but rather ways of describing the cloud environment and the level of abstraction. Workload security models are more focused on the location and ownership of the workloads, and how they are secured. The two main workload security models are off-premises and on-premises. Off-premises workload security model means that the workloads are hosted and managed by a third-party cloud service provider, such as AWS, Azure, or GCP. The cloud service provider is responsible for the security of the underlying infrastructure, such as the physical servers, network devices, storage systems, and hypervisors. The customer is responsible for the security of the workloads themselves, such as the guest operating systems, applications, data, and users. The customer can use various tools and techniques to secure their workloads, such as encryption, firewalls, identity and access management, vulnerability scanning, and logging and monitoring. On-premises workload security model means that the workloads are hosted and managed by the customer on their own data center or private cloud. The customer is responsible for the security of both the infrastructure and the workloads, and has full control and visibility over them. The customer can use similar tools and techniques as the off-premises model, but also has to deal with the physical security, network security, and compliance requirements of their own environment. References:

The crypto isakmp key command is used to configure a preshared key for ISAKMP authentication between two peers. The address 0.0.0.0 indicates that the key is valid for any peer address. Therefore, the same command must be entered on hostB with the same password in order to establish the tunnel with hostA. Changing the protocol to ikev2, using a different password, or changing the password to the default will not solve the problem, as they will create a mismatch in the authentication parameters. References:

Explanation

Cisco DNA Center has four general sections aligned to IT workflows:

Design: Design your network for consistent configurations by device and by site. Physical maps and logical topologies help provide quick visual reference. The direct import feature brings in existing maps, images, and topologies directly from Cisco Prime Infrastructure and the Cisco Application Policy Infrastructure Controller

Enterprise Module (APIC-EM), making upgrades easy and quick. Device configurations by site can be

consolidated in a “golden image” that can be used to automatically provision new network devices. These new devices can either be pre-staged by associating the device details and mapping to a site. Or they can be claimed upon connection and mapped to the site.

Policy: Translate business intent into network policies and apply those policies, such as access control, traffic routing, and quality of service, consistently over the entire wired and wireless infrastructure. Policy-based access control and network segmentation is a critical function of the Cisco Software-Defined Access (SDAccess) solution built from Cisco DNA Center and Cisco Identity Services Engine (ISE). Cisco AI Network Analytics and Cisco Group-Based Policy Analytics running in the Cisco DNA Center identify endpoints, group similar endpoints, and determine group communication behavior. Cisco DNA Center then facilitates creating policies that determine the form of communication allowed between and within members of each group. ISE then activates the underlying infrastructure and segments the network creating a virtual overlay to follow these

policies consistently. Such segmenting implements zero-trust security in the workplace, reduces risk, contains

threats, and helps verify regulatory compliance by giving endpoints just the right level of access they need.

Provision: Once you have created policies in Cisco DNA Center, provisioning is a simple drag-and-drop task.

The profiles (called scalable group tags or “SGTs”) in the Cisco DNA Center inventory list are assigned a policy, and this policy will always follow the identity. The process is completely automated and zero-touch. New devices added to the network are assigned to an SGT based on identity—greatly facilitating remote office setups.

Assurance: Cisco DNA Assurance, using AI/ML, enables every point on the network to become a sensor, sending continuous streaming telemetry on application performance and user connectivity in real time. The clean and simple dashboard shows detailed network health and flags issues. Then, guided remediation

automates resolution to keep your network performing at its optimal with less mundane troubleshooting work.

The outcome is a consistent experience and proactive optimization of your network, with less time spent on troubleshooting tasks.

Umbrella Roaming is a cloud-delivered security service for Cisco’s next-generation firewall. It protects your employees even when they are off the VPN.

The Cisco Endpoint IoC feature is a powerful incident response tool for scanning of post-compromise indicators across multiple computers. Endpoint IoCs are imported through the console from OpenIOC-based files written to trigger on file properties such as name, size, hash, and other attributes and system properties such as process information, running services, and Windows Registry entries. The IoC syntax can be used by incident responders to find specific artifacts or use logic to create sophisticated, correlated detections for families of malware. Endpoint IoCs have the advantage of being portable to share within your organization or in industry vertical forums and mailing lists. The Endpoint IoC scanner is available in AMP for Endpoints Windows Connector versions 4 and higher. Running Endpoint IoC scans may require up to 1 GB of free drive space. The Endpoint IoC feature is based on the openioc.com framework, which is an open standard for sharing threat intelligence. References:
