Multifactor 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 VPN1. MFA is a core component of a strong identity and access management (IAM) policy. MFA can help prevent an attacker from stealing usernames and passwords of users within an organization by adding an extra layer of security beyond the traditional username and password. For example, a user may need to enter a one-time code sent to their phone or email, scan their fingerprint, or use a hardware token to prove their identity. This way, even if an attacker obtains the user’s credentials, they cannot access the resource without the second factor2.

The other options are not technologies that can help prevent an attacker from stealing usernames and passwords of users within an organization. RADIUS-based REAP is a protocol that allows wireless clients to authenticate with a RADIUS server, but it does not provide MFA3. Fingerprinting is a technique that identifies the operating system or application of a device based on its network characteristics, but it does not provide MFA4. Dynamic ARP Inspection is a security feature that prevents ARP spoofing attacks by validating ARP packets, but it does not provide MFA5.

 Cl/CD pipelining is a method of software development that aims to deliver software faster and more reliably by automating the process of integrating, testing, and deploying code changes. Cl stands for continuous integration, which means that every code change is merged into a shared repository and verified by automated tests. CD stands for continuous delivery, which means that the code is always in a deployable state and can be released to production environments with minimal human intervention. Cl/CD pipelining enables developers to collaborate more effectively, detect and fix errors earlier, and deliver value to customers more frequently. Cl/CD pipelining is a key practice of DevOps, a culture and set of processes that bridge the gap between development and operations teams. References:

ETHOS is the Cisco file grouping engine. It allows us to group families of files together so if we see variants of

a malware, we mark the ETHOS hash as malicious and whole families of malware are instantly detected.

A Simple Custom Detection List is a feature of Cisco AMP for Endpoints that allows administrators to create a list of SHA-256 hashes of files that they want to detect, block, and quarantine on their endpoints. The list can be applied to a policy and the connectors will synchronize with the latest changes. However, the list only works with the exact SHA-256 hashes that are provided, and it does not detect any variations or modifications of the files. Therefore, if the malicious file abc428565580xyz.exe has been altered in any way, such as by changing its name, size, or content, the Simple Custom Detection List will not be able to recognize it as a threat. To ensure detection of the malicious file, the administrator must upload the SHA-256 hash of the current version of the file to the Simple Custom Detection List, or use another method that can detect file variations, such as an Advanced Custom Detection List or Cisco Threat Grid. References :=

A simple custom detection list is a feature of AMP for Endpoints that allows you to specify a list of file hashes (MD5, SHA-1, or SHA-256) that you want to detect, block, and quarantine on your endpoints. You can create a simple custom detection list from the Outbreak Control section of the AMP for Endpoints console, and apply it to a policy that is assigned to your endpoints. When the AMP connector on the endpoint encounters a file that matches the hash in the list, it will perform the action that you specified, such as blocking the file execution, sending an alert, or quarantining the file. A simple custom detection list is useful when you want to quickly and easily block specific files that are known to be malicious or unwanted, without having to create a complex signature or rule12 References := 1: Configure a Simple Custom Detection List on the AMP for Endpoints Portal 2: Create an Advanced Custom Detection List in Cisco Secure Endpoint

Explanation

In deceptive phishing, fraudsters impersonate a legitimate company in an attempt to steal people’s personal data or login credentials. Those emails frequently use threats and a sense of urgency to scare users into doing what the attackers want.

Spear phishing is carefully designed to get a single recipient to respond. Criminals select an individual target within an organization, using social media and other public information – and craft a fake email tailored for that person.

Explanation

CoA Messages are sent on two different udp ports depending on the platform. Cisco standardizes on UDP port

1700, while the actual RFC calls out using UDP port 3799.

Explanation

The telemetry information consists of three types of data:

+ Flow information: This information contains details about endpoints, protocols, ports, when the flow started,

how long the flow was active, etc.

+ Interpacket variation: This information captures any interpacket variations within the flow. Examples include

variation in Time To Live (TTL), IP and TCP flags, payload length, etc

+ Context details: Context information is derived outside the packet header. It includes details about variation in buffer utilization, packet drops within a flow, association with tunnel endpoints, etc.

 PAC files are scripts that tell web browsers how to use proxies on the network. They use if-else statements to determine whether to use a proxy or a direct connection for traffic between the PC and the host, based on criteria such as the destination URL, the source IP address, or the network subnet12. The WSA can host PAC files on port 9001 by default, and this port can be changed in the PAC file hosting settings2. If the WSA host port is changed, the default port does not redirect web traffic to the correct port automatically; the browser needs to point to the new port in the PAC file URL2. The WSA does not host PAC files on port 6001 by default2. PAC files do not direct traffic through a proxy when the PC and the host are on the same subnet by default; this behavior depends on the PAC file logic12. References:

To share data between multiple security products, you must use Cisco Platform Exchange Grid (pxGrid). pxGrid is an open and scalable framework that allows for bi-directional any-to-any partner platform integrations. pxGrid uses REST and WebSocket interfaces to exchange intelligence and obtain contextual information from Cisco Identity Services Engine (ISE) and other security products. pxGrid can also direct ISE to contain threats by setting network policies. pxGrid enables cross-platform network system collaboration across your IT infrastructure and helps you monitor security, detect threats, and manage assets, configuration, identity, and access. References: Introduction to the Cisco Platform Exchange Grid (pxGrid) in ISE, Cisco Identity Services Engine Administrator Guide, Release 3.3

 EPP solutions solely focus on the perimeter of the network, which is the boundary between the internal and external networks. The perimeter is where most of the endpoints, such as laptops, desktops, mobile devices, and IoT devices, are located and connected to the network. EPP solutions aim to prevent, detect, and remediate security threats on these endpoints by using technologies such as antivirus, data encryption, and data loss prevention. EPP solutions rely on signatures and other indicators of intrusion by known threats to block malicious activity and malware on the endpoints12.

EDR solutions do not focus on the perimeter, but rather on the entire network, including the core and the East-West gateways. The core is the central part of the network that connects different segments and provides high-speed data transmission. The East-West gateways are the points of communication between different segments within the network, such as between different data centers or cloud environments. EDR solutions provide continuous and comprehensive visibility into endpoint activities across the network by using threat hunting tools for behavior-based endpoint threat detection. EDR solutions monitor and record endpoint data, detect anomalies and malicious behavior, and respond to threats that EPP and other security tools did not catch. EDR solutions also enable security teams to proactively investigate and contain incidents by using incident data search, alert triage, threat validation, and malicious activity blocking134.

Cisco AMP (Advanced Malware Protection) is a technology that provides a combination of endpoint protection, endpoint detection, and response. Cisco AMP protects endpoints from malware and other threats by using multiple prevention engines, including signatures, machine learning, and file reputation. Cisco AMP also continuously monitors and analyzes endpoint activity to detect malicious behavior and indicators of compromise. Cisco AMP can respond to threats by blocking, isolating, or removing malicious files, processes, or devices across the network. Cisco AMP leverages the cloud-based intelligence of Cisco Talos and Cisco Threat Grid to provide global threat visibility and analysis. Cisco AMP can also integrate with Cisco Umbrella and other security solutions to provide a comprehensive and unified approach to endpoint security. References:

Explanation

Domain name system (DNS) is the protocol that translates human-friendly URLs, such as securitytut.com, into IP addresses, such as 183.33.24.13. Because DNS messages are only used as the beginning of each communication and they are not intended for data transfer, many organizations do not monitor their DNS traffic for malicious activity. As a result, DNS-based attacks can be effective if launched against their networks. DNS tunneling is one such attack.

An example of DNS Tunneling is shown below:

The attacker incorporates one of many open-source DNS tunneling kits into an authoritative DNSnameserver (NS) and malicious payload.2. An IP address (e.g. 1.2.3.4) is allocated from the attacker’s infrastructure and a domain name (e.g. attackerdomain.com) is registered or reused. The registrar informs the top-level domain (.com) nameservers to refer requests for attackerdomain.com to ns.attackerdomain.com, which has a DNS record mapped to 1.2.3.43. The attacker compromises a system with the malicious payload. Once the desired data is obtained, the payload encodes the data as a series of 32 characters (0-9, A-Z) broken into short strings (3KJ242AIE9, P028X977W,…).4. The payload initiates thousands of unique DNS record requests to the attacker’s domain with each string as

Transparent traffic redirection using WCCP is a deployment mode for the Cisco WSA that allows it to intercept and proxy web requests from client applications without requiring any configuration on the clients. This mode increases the visibility and control of web traffic, while making the proxy function invisible to the users. To support this mode, the Cisco WSA must be configured to use the transparent proxy mode, which enables it to listen on ports 80 and 443 for HTTP and HTTPS traffic, respectively. The Cisco WSA must also be configured to use WCCP service IDs, which are numerical identifiers that specify the type and range of ports to be redirected. For example, service ID 0 (web-cache) redirects port 80, service ID 70 (https-cache) redirects port 443, and service ID 60 (ftp-native) redirects port 21 and a range of passive FTP ports. The Cisco WSA must also be configured to join a WCCP group, which is a set of WCCP routers or switches that cooperate to redirect traffic to the WSA. The WCCP group can be specified by a group list, which is an access list that defines the IP addresses of the WCCP routers or switches, or by a password, which is a shared secret that authenticates the WCCP communication. The WCCP group must also be configured on the network device that performs the traffic redirection, such as a Cisco router, switch, or ASA firewall. The network device must support WCCPv2, which is the latest version of the protocol that allows for advanced features such as load balancing, encryption, and GRE encapsulation. The network device must also be configured to use the same WCCP service IDs and group list or password as the Cisco WSA. The network device must also be configured to apply the WCCP redirection to the appropriate interface and direction, such as the inside interface and inbound direction for traffic originating from the internal network. The network device must also be configured to use an access list that defines the traffic to be redirected or bypassed, such as the source and destination IP addresses, ports, and protocols. The access list can also be used to exclude certain traffic from WCCP redirection, such as traffic to private or internal destinations, or traffic from specific hosts123 References := 1: Configure Transparent Redirection With WCCP in Order to Redirect Native FTP Traffic - Cisco 2: Solved: Transparent Redirection - Cisco Community 3: Cisco WSA : Is it possible to use web proxy in transparent mode without WCCP - Cisco Community

The Application Visibility and Control (AVC) engine lets you create policies to control application activity on the network without having to fully understand the underlying technology of each application. You can configure application control settings in Access Policy groups. You can block or allow applications individually or according to application type. You can also apply controls to particular application types.

 The Python script of the Cisco DNA Center API in the exhibit uses the requests module to send a GET request to the /dna/intent/api/v1/network-device endpoint, which returns a list of network devices managed by Cisco DNA Center. The script also uses HTTPBasicAuth to provide the username and password for authentication. The script then parses the JSON response and prints the hostname, type, management IP address, and software version of each device in a table format using the prettytable module. Therefore, the result of this script is to receive information about a switch or switches from Cisco DNA Center. References:

Northbound APIs (SDN northbound APIs) are typically RESTful APIs that are used to communicate between the SDN controller and the services and applications running over the network. Such northbound APIs can be used for the orchestration and automation of the network components to align with the needs of different applications via SDN network programmability1. The management solution is an example of an application that can use the northbound APIs to interact with the SDN controller and configure, monitor, and troubleshoot the network devices and services2. Therefore, the main function of northbound APIs in the SDN architecture is to enable communication between the SDN controller and the management solution. References: 1: What are SDN Northbound APIs (and SDN Rest APIs)? - SDxCentral 2: Software-Defined Networking Security and Network Programmability

 To enable CWA for wireless guest access, the ISE engineer needs to configure the following steps on the ISE server:

Create a guest portal with the desired settings and appearance.

Create an authorization profile that references the guest portal and the DACL name for the Airespace ACL configured on the WLC. The DACL name must match the name of the ACL on the WLC exactly. The authorization profile also needs to have the common tasks of Web Redirection and Web Authentication enabled.

Create an authorization policy that matches the unauthenticated devices based on the MAC address or other criteria and applies the authorization profile created in the previous step.

The DACL name is required for the WLC to apply the correct ACL to the guest endpoints and redirect them to the guest portal. Without the DACL name, the WLC will not know which ACL to use and may grant full guest access to the endpoints. Therefore, the correct answer is D.

The command show authorization status displays the authorization status for the current user. The command show connection status gi0/1 is not a valid Cisco command. The command show ver gi0/1 displays the version information for the interface gi0/1. References: 802.1X Authentication Commands, Configuring IEEE 802.1x Port-Based Authentication, What Cisco command shows you the status of an 802.1X connection on interface gi0/1?

To block all subdomains of domain.com, the administrator should configure the domain.com address in the block list. This is because Umbrella automatically applies a left side and right side wildcard to every domain in a block or allow destination list. Therefore, adding domain.com to a block list will result in requests to domain.com or its subdomains, such as www.domain.com, being blocked. Adding a wildcard character (*) is not supported and will not work. Adding the *.com address in the block list will block all domains that end with .com, which is not the desired outcome. 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.
