We should scan emails using AntiVirus signatures to make sure there are no viruses attached in emails.

Note: A virus signature is the fingerprint of a virus. It is a set of unique data, or bits of code, that allow it to be identified. Antivirus software uses a virus signature to find a virus in a computer file system, allowing to detect, quarantine, and remove the virus.

SenderBase is an email reputation service designed to help email administrators research senders, identify legitimate sources of email, and block spammers. When the Cisco ESA receives messages from known or highly reputable senders, it delivers them directly to the end user without any content scanning. However, when the Cisco ESA receives email messages from unknown or less reputable senders, it performs antispam and antivirus scanning.

The difference between GRE over IPsec and IPsec with crypto map is that GRE (Generic Routing Encapsulation) over IPsec can encapsulate and transport non-IP protocols across an IP network, whereas IPsec with crypto map is typically used for IP traffic. GRE tunnels wrapped in IPsec provide a way to transport multicast traffic and other protocol types across an IPsec VPN, offering greater flexibility in the types of traffic that can be secured.

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.
