Cisco FTDv is a virtual appliance that combines the features of Cisco ASA and Cisco Firepower NGIPS. It provides stateful firewall, IPS, URL filtering, malware protection, and other advanced security functions. Cisco ASAv is a virtual appliance that only provides stateful firewall and VPN features. It does not support URL filtering or other Firepower functions. Therefore, Cisco FTDv provides more features than ASAv, especially for next-generation firewall capabilities. References :=

 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.

Explanation

Explanation

The traditional use of the pull model, where the client requests data from the network does not scale when what you want is near real-time data. Moreover, in some use cases, there is the need to be notified only when some data changes, like interfaces status, protocol neighbors change etc.

Model-Driven Telemetry is a new approach for network monitoring in which data is streamed from network devices continuously using a push model and provides near real-time access to operational statistics.

Applications can subscribe to specific data items they need, by using standard-based YANG data models over NETCONF-YANG. Cisco IOS XE streaming telemetry allows to push data off of the device to an external collector at a much higher frequency, more efficiently, as well as data on-change streaming.

 Cisco Web Security Appliance (WSA) is the platform that automatically blocks risky sites, and tests unknown sites for hidden advanced threats before allowing users to click them, using Cisco Cognitive Threat Analytics. Cisco Cognitive Threat Analytics is a cloud-based solution that reduces the time to discovery of threats operating inside the network by analyzing web traffic and detecting anomalous behavior. Cisco WSA integrates with Cisco Cognitive Threat Analytics to provide enhanced web security and breach detection. Cisco WSA can also leverage other Cisco security solutions, such as Cisco Umbrella, Cisco Advanced Malware Protection (AMP), and Cisco Talos Intelligence Group, to provide comprehensive web security. References:

Mobile device management (MDM) is a solution that allows organizations to manage and secure mobile devices such as smartphones and tablets. MDM can provide two security benefits:

Robust security policy enforcement: MDM can enforce strong security practices and hygiene by defining unified settings that can be applied across your fleet. This centralized software ensures all devices are continuously staying in compliance. For example, MDM can configure settings like full-disk encryption, screen locks, password policies, device restrictions, VPN, firewall, antivirus, and more. MDM can also prevent unwanted or risky software from being installed, and remotely lock or wipe devices if they are lost, stolen, or compromised1.

Privacy control checks: MDM can help organizations stay compliant with privacy regulations and protect sensitive data from unauthorized access. MDM can segment personal and corporate data on devices, and selectively wipe only corporate data when needed. MDM can also monitor device usage and location, and alert administrators of any suspicious or anomalous behavior. MDM can also provide secure containers for sensitive documents and content, and encrypt data in transit and at rest23.

To create an access control list (ACL) on a Cisco Adaptive Security Appliance (ASA) firewall, you need to use the access-list command followed by the name of the ACL, the action (permit or deny), the protocol, the source address and mask, and the destination address and mask. For example, to permit HTTP traffic from the inside network 192.168.1.0/24 to any destination on the internet, you can use this command:

access-list inside_access_in permit tcp 192.168.1.0 255.255.255.0 any eq www

This command creates an ACL named inside_access_in that permits TCP traffic from the source network 192.168.1.0/24 to any destination with the destination port equal to 80 (www). The eq keyword is used to specify the port number or name. You can also use the range keyword to specify a range of ports.

To apply the ACL to an interface, you need to use the access-group command followed by the name of the ACL and the direction (in or out). For example, to apply the ACL to the inside interface in the inbound direction, you can use this command:

access-group inside_access_in in interface inside

This command applies the ACL inside_access_in to the interface named inside in the inbound direction. This means that the ACL will filter the traffic that enters the firewall through the inside interface.

Option D is the only option that matches the syntax of the access-list command for the ASA firewall. Option A is incorrect because it uses the ip keyword instead of the tcp keyword. Option B is incorrect because it uses the any keyword for both the source and destination addresses. Option C is incorrect because it uses the host keyword for the source address, which is not valid for a network address.

create an application control blocked applications list. This option allows you to specify a list of files that you want to prevent from running on the endpoints that have the AMP connector installed. The files are identified by their SHA-256 hashes, and you can upload them individually or in a batch. The files are not quarantined, but they are blocked from execution and reported as events in the AMP console1. This option is different from the simple custom detection list, which is used to detect and quarantine specific files that are considered malicious2. The advanced custom detection list is also used to detect and quarantine files, but it allows you to specify more criteria such as file size, file name, and file path3. The IP block and allow lists are used to control the network traffic to and from the endpoints, not the file execution4. References: 1: Configure Application Control on the AMP for Endpoints Portal 2: Configure a Simple Custom Detection List on the AMP for Endpoints Portal 3: [Configure an Advanced Custom Detection List on the AMP for Endpoints Portal] 4: [Configure IP Block and Allow Lists on the AMP for Endpoints Portal]

 The Cisco WSA supports mainly two authentication protocols: LDAP and NTLM. LDAP is a standard protocol for accessing directory services, such as Active Directory or OpenLDAP. NTLM is a proprietary protocol for authenticating Windows clients to Windows servers. NTLM has two versions: NTLMv1 and NTLMv2. NTLMSSP (NT LAN Manager Security Support Provider) is a variant of NTLMv2 that provides additional security features, such as message integrity and confidentiality. The Cisco WSA supports both LDAP and NTLMSSP using basic authentication, which requires the user to enter a username and password. The Cisco WSA also supports Kerberos, which is a network authentication protocol that uses tickets to authenticate users and services. Kerberos is based on symmetric-key cryptography and requires a trusted third party, called the Key Distribution Center (KDC), to issue and validate tickets. Kerberos is more secure and efficient than NTLM, as it does not require the user to enter credentials repeatedly and does not send passwords over the network. The Cisco WSA supports Kerberos only in standard mode, not in cloud connector mode. The Cisco WSA does not support TACACS+ or CHAP as authentication protocols. TACACS+ is a Cisco proprietary protocol for authenticating network devices and users to a central server. CHAP is a challenge-response protocol for authenticating PPP connections. These protocols are not designed for web security appliances and are not compatible with the Cisco WSA. References:

 Cisco Advanced Phishing Protection (AAP) is a solution that adds sophisticated machine learning capabilities to Cisco Email Security to block advanced identity deception attacks for inbound email by assessing its threat posture1. It also uses both global and local telemetry data combined with analytics and modeling to validate the reputation and authenticity of senders2. AAP provides sender authentication and BEC detection capabilities, and uses advanced machine learning techniques, real-time behavior analytics, relationship modeling and telemetry to protect against identity deception–based threats3.

In two ways, the Cisco Advanced Phishing Protection solution protects users:

It prevents use of compromised accounts and social engineering. AAP detects and blocks phishing emails that attempt to impersonate legitimate senders, such as executives, partners, or customers, and trick users into revealing sensitive information or transferring funds. AAP analyzes the sender’s identity, behavior, and relationship with the recipient, and assigns a risk score to the email. If the email is deemed suspicious or malicious, AAP can quarantine it, flag it, or deliver it with a warning4.

It automatically removes malicious emails from users’ inbox. AAP provides retrospective analysis and remediation capabilities, which means that it can identify and remove emails that were initially delivered but later found to be malicious. AAP leverages the Cisco Talos threat intelligence network and the Sensor-based solution to continuously monitor the threat landscape and update the email disposition accordingly. If an email is reclassified as malicious, AAP can automatically delete it from the users’ inbox, or notify the administrator or the user to take action45.

The other options are incorrect because they do not accurately describe the functions of AAP. AAP does not prevent all zero-day attacks coming from the Internet, as it focuses on phishing and identity deception attacks. AAP does not prevent trojan horse malware using sensors, as sensors are used to collect and analyze email data, not to block malware. AAP does not secure all passwords that are shared in video conferences, as it is not related to video conferencing security. Therefore, the correct answer is A and C. References:

EDR stands for endpoint detection and response, while EPP stands for endpoint protection platform. EDR and EPP are two types of endpoint security solutions that have different capabilities and objectives. EDR provides real-time visibility into endpoint activities, detects malicious behavior and anomalies, and enables security teams to investigate and respond to threats. EPP prevents, detects, and remediates security threats on endpoints, such as known and unknown malware, ransomware, and zero-day vulnerabilities. EPP solutions may also include EDR capabilities, but not all EDR solutions include EPP capabilities.

One of the key features of EDR is retrospective analysis, which means the ability to look back at historical endpoint data and identify the root cause, scope, and impact of a security incident. Retrospective analysis helps security teams understand how the threat entered the network, what actions it performed, and how to prevent it from happening again. EPP solutions, on the other hand, do not provide retrospective analysis, as they are mainly focused on preventing and remediating threats, rather than investigating and responding to them.

Therefore, the correct answer is B. Retrospective analysis is a characteristic of an EDR solution and not of an EPP solution.

NetFlow is a Cisco IOS application that provides statistics on packets flowing through the router. NetFlow is based on 7 key fields that identify a flow, such as source and destination IP addresses, source and destination port numbers, layer 3 protocol type, ToS byte, and input logical interface. To enable NetFlow on a router, IP routing must be configured first, because NetFlow relies on IP addresses to classify and monitor traffic. SNMPv3, syslog, and VRF are not required for NetFlow configuration, although they can be used for other purposes such as network management, logging, and virtualization. References:

Defanging is the process of modifying a URL in a message to prevent it from being clickable. This can help protect users from malicious links that have a low URL reputation score. Defanging is one of the actions that can be configured in the Incoming Content Filter on the Cisco ESA. The other actions are Quarantine, FilterAction, and ScreenAction. Quarantine sends the message to a quarantine area for further inspection. FilterAction applies a predefined action such as drop, bounce, or deliver. ScreenAction displays a warning message to the user before allowing them to access the URL. Defanging is the only action that disables the links in the message without affecting the delivery or visibility of the message12. References: 1: URL Filtering on the Cisco IronPort ESA – Mikail’s Blog 2: Configure URL Filtering for Secure Email Gateway and Cloud Gateway - Cisco

A certificate signing request (CSR) is one of the first steps towards getting your own SSL Certificate. Generated on the same server you plan to install the certificate on, the CSR contains information (e.g. common name, organization, country) that the Certificate Authority (CA) will use to create your certificate. It also contains the public key that will be included in your certificate and is signed with the corresponding private key
