In a remote access VPN configuration, dynamic split tunneling allows traffic to certain trusted domains to bypass the VPN tunnel and exit through the client's local internet gateway. This feature selectively directs only the necessary traffic over the VPN, while allowing direct internet access for specific domains or traffic deemed safe or trusted, optimizing bandwidth and performance for remote users.

The kind of API that is used with Cisco DNA Center to provision SSIDs, QoS policies, and update software versions on switches is the Intent API. The Intent API is a category of APIs that allows users to express their desired network outcomes or intents, such as creating a site, adding a device, or deploying a network profile. The Intent API then translates these intents into specific network configurations and commands, and applies them to the relevant network devices and services. The Intent API simplifies and automates the network provisioning and management process, and enables users to focus on the business objectives rather than the technical details. Some examples of Intent APIs are:

Site Management API: This API allows users to create, update, delete, and retrieve sites and buildings in Cisco DNA Center. A site is a logical grouping of network devices and services that share common characteristics, such as location, policies, or functions. A site can have one or more buildings, and a building can have one or more floors. Sites are used to organize and manage the network hierarchy and topology.

Network Settings API: This API allows users to configure and manage network-wide settings, such as global credentials, network discovery, IP address pools, DHCP and DNS servers, and SNMP settings. These settings are applied to all network devices and services that are managed by Cisco DNA Center.

Network Profile API: This API allows users to create, update, delete, and retrieve network profiles in Cisco DNA Center. A network profile is a collection of network settings and policies that define how a network segment or service should operate, such as SSIDs, QoS policies, security policies, and device roles. Network profiles are used to standardize and simplify the network configuration and deployment process, and to ensure consistency and compliance across the network.

Software Image Management API: This API allows users to manage the software images and versions of network devices that are managed by Cisco DNA Center. Users can import, export, delete, and retrieve software images, as well as assign them to network devices or device groups. Users can also schedule and monitor software image updates, and view the software image compliance status of network devices.

 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 :=

An active/active FlexVPN configuration allows for multiple routers or VRFs to act as hubs for different VPN groups, providing load balancing and redundancy1. This is useful when the VPN deployment has a large number of spokes or different security policies for different groups of spokes. DMVPN, on the other hand, only supports a single hub or a pair of hubs in active/standby mode for each VPN group2. This limits the scalability and flexibility of DMVPN deployments. Therefore, an engineer would opt for an active/active FlexVPN configuration as opposed to DMVPN when multiple routers or VRFs are required. References :=

Cisco Advanced Phishing Protection (AAP) is a solution that helps organizations protect against fraudulent senders and identity deception-based attacks, such as business email compromise (BEC) and spear phishing. AAP uses advanced machine learning techniques, real-time behavior analytics, relationship modeling, and telemetry to perform two main functions12:

It determines if the email messages are malicious by assessing the threat posture of the sender and the content of the message. It also validates the reputation and authenticity of the sender by checking various indicators, such as the domain, the IP address, the SPF, DKIM, and DMARC records, the display name, the reply-to address, and the header information. AAP assigns a risk score to each email message and provides a verdict of clean, malicious, or suspicious. It also adds a banner to the email message to inform the recipient of the risk level and the recommended action.

It does a real-time user web browsing behavior analysis by monitoring the user’s interaction with the email message and the links embedded in it. It tracks the user’s clicks, mouse movements, dwell time, and other indicators to detect any signs of hesitation, confusion, or curiosity. It also analyzes the destination URL of the links and compares it with the known malicious websites. If AAP detects any anomalous or risky behavior, it intervenes with a warning message or a redirect page to educate the user and prevent them from falling victim to the phishing attack. References := 1: Cisco’s Security Innovations to Protect the Endpoint and Email 2: Cisco Advanced Phishing Protection - Cisco Video Portal

 Multi-factor authentication (MFA) is an authentication method that requires the user to provide two or more verification factors to gain access to a resource such as an application, online account, or a VPN. MFA is a core component of a strong identity and access management (IAM) policy1. MFA is important to implement inside of an organization because it can prevent brute force attacks from being successful. A brute force attack is a type of cyberattack that tries to guess the user’s password or PIN by trying different combinations until it finds the correct one. This can be done manually or with automated tools. MFA can stop brute force attacks by requiring an additional factor of authentication that the attacker does not have, such as a phone, a token, a biometric, or a location. MFA can also reduce the risk of other types of attacks that rely on stealing or compromising the user’s credentials, such as phishing, keylogging, or credential stuffing. References := 1: What is Multi-Factor Authentication (MFA)? | OneLogin

Cisco Tetration is a hybrid-cloud workload protection platform that secures compute instances in both the on-premises data center and the public cloud1. One of the benefits of using Cisco Tetration is that it collects telemetry data from servers and then uses software sensors to analyze flow information2. This allows Cisco Tetration to provide comprehensive visibility into every workload interaction and powerful AI/ML driven automation2. By analyzing the flow information, Cisco Tetration can also generate microsegmentation policies, detect workload behavior anomalies, identify software vulnerabilities, and monitor policy compliance23. References: 1: Cisco Secure Workload (formerly Tetration) FAQ 2: Cisco Secure Workload Platform Data Sheet 3: Cisco Tetration Platform - Cisco

Talos Intelligence is a comprehensive threat intelligence service that provides up-to-date information on URL filtering, reputations, and vulnerability information. Talos Intelligence can be integrated with Cisco FTD and Cisco WSA to enhance the security and visibility of the network. Cisco FTD and Cisco WSA can leverage the Talos Intelligence feeds to perform Security Intelligence filtering, which allows the devices to block or allow traffic based on the reputation of the source or destination IP addresses, URLs, or DNS requests. Talos Intelligence feeds are updated regularly and can be configured to download automatically or manually on the FTD and WSA devices12345. References := 1: Cisco Talos Intelligence Group - Comprehensive Threat Intelligence 2: Threat Intelligence on Cisco Stealthwatch - Cisco Community 3: Third-Party Integration of Security Feeds with FMC (Cisco Threat … - Cisco Community 4: Cisco Firepower Threat Defense Configuration Guide for Firepower Device … 5: Cisco Firepower Threat Defense Configuration Guide for Firepower Device …

Device compliance checks are used to verify that the devices managed by Intune meet the security and configuration requirements defined by the organization. Device compliance checks can use various parameters to evaluate the device state, such as:

Endpoint protection software version: This parameter checks if the device has a valid and up-to-date antivirus or antimalware software installed and running. This parameter helps to protect the device from malicious software and network attacks.

Device operating system version: This parameter checks if the device has the minimum or maximum operating system version supported by the organization. This parameter helps to ensure that the device has the latest security patches and features available.

Windows registry values: This parameter checks if the device has specific registry values configured or not. This parameter helps to enforce custom settings or policies on the device that are not covered by other parameters.

DHCP snooping checks: This parameter checks if the device is connected to a trusted network that uses DHCP snooping to prevent rogue DHCP servers from assigning IP addresses to the device. This parameter helps to prevent man-in-the-middle attacks and network spoofing.

DNS integrity checks: This parameter checks if the device is using a secure and reliable DNS server that can resolve domain names correctly and prevent DNS hijacking or poisoning. This parameter helps to prevent phishing and redirection attacks.

Anycast IP is a component of Cisco umbrella architecture that increases reliability of the service by allowing the same IP address to exist on multiple servers around the world. This way, the user’s request is automatically routed to the nearest and fastest data center, and failover is seamless in case of an outage. Anycast IP also reduces latency and improves performance by using BGP to select the shortest path to the destination12. References := 1: Why Cisco Umbrella uses anycast routing - Cisco Umbrella 2: Cisco Umbrella At a Glance

Cisco AMP for Endpoints is a next generation endpoint security solution that provides prevention, detection, and response capabilities. One of its functions is to automate threat responses of an infected host by isolating it from the network, blocking malicious files, and removing them from all endpoints. This reduces the time and effort required to contain and remediate a threat, and prevents further damage or data loss. According to the source book, Cisco AMP for Endpoints can perform the following automated responses1:

Endpoint Isolation: This feature allows you to isolate an endpoint from the network if it is compromised or infected. This prevents the endpoint from communicating with other devices or servers, and stops the spread of malware or exfiltration of data. You can isolate an endpoint manually from the console, or automatically based on a policy or a detection. You can also restore the network connectivity of an isolated endpoint when it is safe to do so.

File Blocking: This feature allows you to block a file from executing on any endpoint if it is deemed malicious or suspicious. You can block a file manually from the console, or automatically based on a policy or a detection. You can also unblock a file if it is a false positive or no longer a threat.

File Removal: This feature allows you to remove a file from any endpoint if it is malicious or unwanted. You can remove a file manually from the console, or automatically based on a policy or a detection. You can also restore a file from quarantine if it is a false positive or needed for analysis.

As the new device does not have a supplicant, we cannot use 802.1X.

MAC Authentication Bypass (MAB) is a fallback option for devices that don’t support 802.1x. It is virtually

always used in deployments in some way shape or form. MAB works by having the authenticator take the

connecting device’s MAC address and send it to the authentication server as its username and password. The authentication server will check its policies and send back an Access-Accept or Access-Reject just like it would with 802.1x.

Cisco ISE Profiling Services provides dynamic detection and classification of endpoints connected to the

network. Using MAC addresses as the unique identifier, ISE collects various attributes for each network

endpoint to build an internal endpoint database. The classification process matches the collected attributes to prebuilt or user-defined conditions, which are then correlated to an extensive library of profiles. These profiles include a wide range of device types, including mobile clients (iPads, Android tablets, Chromebooks, and so

on), desktop operating systems (for example, Windows, Mac OS X, Linux, and others), and numerous non-user systems such as printers, phones, cameras, and game consoles.

Once classified, endpoints can be authorized to the network and granted access based on their profile. For example, endpoints that match the IP phone profile can be placed into a voice VLAN using MAC Authentication Bypass (MAB) as the authentication method. Another example is to provide differentiated network access to users based on the device used. For example, employees can get full access when accessing the network from their corporate workstation but be granted limited network access when accessing the network from their personal iPhone.
