 Installing the Cisco Umbrella root CA onto the user’s device is the action that accomplishes the goal of inspecting traffic without alerting end-users. This is because the root CA allows the user’s device to trust the certificates issued by the Cisco Umbrella intelligent proxy, which acts as a man-in-the-middle for SSL sites on Umbrella’s grey list. Without the root CA, the user’s browser would raise errors when accessing those sites, as it would detect an untrusted certificate. By installing the root CA, the user’s browser would accept the certificate and allow the traffic to be proxied and inspected by the intelligent proxy. References:

The switch port MAC address security setting that must be used is sticky. This option allows the switch to dynamically learn the MAC addresses of the devices connected to the port and add them to the running configuration. If the port is shut down or the switch is restarted, the MAC addresses remain associated with the port and are not aged out. This way, the engineer can limit the number of MAC addresses per port and prevent unauthorized devices from accessing the network. The sticky option also allows the engineer to manually configure some MAC addresses and let the switch learn the rest. References:

Explanation

DTLS is used for delay sensitive applications (voice and video) as its UDP based while TLS is TCP based.

Therefore DTLS offers strongest throughput performance. The throughput of DTLS at the time of AnyConnect connection can be expected to have processing performance close to VPN throughput.

Explanation

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.

Easy Connect simplifies network access control and segmentation by allowing the assignment of Security

Group Tags to endpoints without requiring 802.1X on those endpoints, whether using wired or wireless

connectivity.

Explanation

SSL Decryption is an important part of the Umbrella Intelligent Proxy. he feature allows the Intelligent Proxy to go beyond simply inspecting normal URLs and actually proxy and inspect traffic that’s sent over HTTPS. The SSL Decryption feature does require the root certificate be installed.

When supporting personal devices on a corporate network, you must protect network services and enterprise

data by authenticating and authorizing users (employees, contractors, and guests) and their devices. Cisco ISE

provides the tools you need to allow employees to securely use personal devices on a corporate network.

Guests can add their personal devices to the network by running the native supplicant provisioning (Network

Setup Assistant), or by adding their devices to the My Devices portal.

Because native supplicant profiles are not available for all devices, users can use the My Devices portal to add

these devices manually; or you can configure Bring Your Own Device (BYOD) rules to register these devices.

Data is sent out to the attacker during a DNS tunneling attack as part of the domain name. DNS tunneling is a technique that encodes the data of other protocols or programs in DNS queries and responses. The attacker registers a domain, such as badsite.com, and points it to a server under their control, where a tunneling program is installed. The attacker infects a device with malware, which sends DNS queries to the attacker’s server, using subdomains of badsite.com to encode the data. For example, the malware could send a query for 1234.badsite.com, where 1234 is the encoded data. The attacker’s server decodes the data from the subdomain and sends back a DNS response, which may also contain encoded data in the answer section12. The other options are not correct, because they do not use the domain name to encode the data. The UDP/53 and TCP/53 packet payload and header are used to transport the DNS query and response, but they are not modified by the tunneling technique. The DNS response packet contains the answer to the query, but it is not the only way to send data to the attacker3. References:

Depending on your company policy, you might be able to use your mobile phones, tablets, printers, Internet radios, and other network devices on your company’s network. You can use the My Devices portal to register and manage these devices on your company’s network.

A connector is a feature that enables a Cisco ISR to use the default bypass list automatically for web filtering. A connector is a software component that runs on the ISR and communicates with the Cloud Web Security service. The connector intercepts the web traffic from the branch users and redirects it to the Cloud Web Security service for scanning and policy enforcement. The connector also maintains a default bypass list, which contains the domains and URLs that are not redirected to the Cloud Web Security service. The default bypass list is updated automatically by the Cloud Web Security service and can be customized by the administrator. The default bypass list helps to improve the performance and reliability of the web filtering solution by avoiding unnecessary redirections of trusted or sensitive web traffic12. References: 1: Security Configuration Guide: Cloud Web Security, Cisco IOS Release 15M & T - Cisco Integrated Services Routers Generation 2 with Cisco Cloud Web Security Solution [Support] - Cisco 2: Security Configuration Guide: Cloud Web Security, Cisco IOS Release 15M & T - Configuring Cloud Web Security on Integrated Services Routers Generation 2 [Support] - Cisco

 MAB is a fallback authentication method for devices that do not support 802.1X. When MAB is enabled on a switchport, the switch will first try 802.1X and if it fails, it will use the MAC address of the device as the username and password to authenticate it with a RADIUS server. The RADIUS server must have a database of MAC addresses that are allowed on the network. MAB can also support dynamic VLAN assignment and ACLs from the RADIUS server. MAB is not a very secure method because MAC addresses can be easily spoofed or changed. Therefore, MAB should be used with caution and only for devices that cannot use 802.1X. References :=

A mobile device management (MDM) solution is a software tool that helps organizations manage, secure, and monitor mobile devices such as smartphones, tablets, and laptops. Some of the benefits of using an MDM solution are:

A. grants administrators a way to remotely wipe a lost or stolen device: This feature allows administrators to erase all the data and settings on a device that is lost or stolen, preventing unauthorized access to sensitive information. This can also help comply with data protection regulations and policies12

E. allows for centralized management of endpoint device applications and configurations: This feature enables administrators to control the applications and settings on the devices, such as enforcing security policies, installing or updating software, configuring network access, and restricting device features. This can help improve productivity, performance, and compliance of the devices13

Other benefits of using an MDM solution are:

B. provides simple and streamlined login experience for multiple applications and users: This feature allows users to access multiple applications and services with a single sign-on (SSO) or multi-factor authentication (MFA) mechanism, reducing the hassle of remembering and entering multiple credentials. This can also enhance security and user satisfaction4

C. native integration that helps secure applications across multiple cloud platforms or on-premises environments: This feature allows applications to leverage the native security features of the devices, such as encryption, biometric authentication, and device attestation. This can also help protect the applications from malware, tampering, and data breaches across different environments.

D. encrypts data that is stored on endpoints: This feature allows data to be encrypted at rest and in transit on the devices, preventing unauthorized access or interception of the data. This can also help comply with data protection regulations and policies.
