Fortinet NSE7_ZTA-7.2 Fortinet NSE 7 - Zero Trust Access 7.2 Exam Practice Test

 With the increase in IoT devices, enterprises face many challenges in securing and managing their network and data. Two of the most significant challenges are:

• Unpatched vulnerabilities in IoT devices (Option C): IoT devices are often vulnerable to cyber attacks due to their increased exposure to the internet and their limited computing resources. Some of the security challenges in IoT include weak password protection, lack of regular patches and updates, insecure interfaces, insufficient data protection, and poor IoT device management12. Unpatched vulnerabilities in IoT devices can allow hackers to exploit them and compromise the network or data. For example, the Mirai malware infected IoT devices by using default credentials and created a massive botnet that launched DDoS attacks on internet services2.
• Achieving full network visibility (Option D): IoT devices can generate a large amount of data that needs to be collected, processed, and analyzed. However, many enterprises lack the tools and capabilities to monitor and manage the IoT devices and data effectively. This can result in poor performance, inefficiency, and security risks. Achieving full network visibility means having a clear and comprehensive view of all the IoT devices, their status, their connectivity, their data flow, and their potential threats. This can help enterprises optimize their network performance, ensure data quality and integrity, and detect and prevent any anomalies or attacks3.

The exhibit shows the EMS Settings where various configurations related to network security are displayed. Option C is correct because, in the settings, it is indicated that HTTPS port is used (which operates over TCP) and SSL certificates are involved in securing the connection, implying the use of TLS for encryption and secure communication between FortiClient and FortiClient EMS.

Option A is incorrect because the domain that FortiClient is connecting to does not have to match the domain to which the certificate is issued. The certificate is issued by the ZTNA CA, which is a separate entity from the domain. The certificate only contains the device ID, ZTNA tags, and other information that are used to identify and authenticate the device.

Option B is incorrect because if the FortiClient EMS server certificate is invalid, FortiClient does not connect silently. Instead, it performs the Invalid Certificate Action that is configured in the settings. The Invalid Certificate Action can be set to block, warn, or allow the connection.

Option D is incorrect because default_ZTNARoot CA does not sign the FortiClient certificate for the SSL connectivity to FortiClient EMS. The FortiClient certificate is signed by the ZTNA CA, which is a different certificate authority from default_ZTNARoot CA. default_ZTNARoot CA is the EMS CA Certificate that is used to verify the identity of the EMS server.

In FortiNAC, to isolate rogue hosts, you should enable the:

• C. Forced Remediation: This port group membership is used to isolate hosts that have been determined to be non-compliant or potentially harmful. It enforces a remediation process on the devices in this group, often by placing them in a separate VLAN or network segment where they have limited or no access to the rest of the network until they are remediated.

The other options are not specifically designed for isolating rogue hosts:

• A. Forced Authentication: This is used to require devices to authenticate before gaining network access.
• B. Forced Registration: This group is used to ensure that all devices are registered before they are allowed on the network.
• D. Reset Forced Registration: This is used to reset the registration status of devices, not to isolate them.

FortiAnalyzer playbooks are automated workflows that can perform actions based on triggers, conditions, and outputs. One of the actions that a playbook can perform is to quarantine a device by sending an API call to FortiClient EMS, which then instructs the FortiClient agent on the device to disconnect from the network. This can help isolate and contain a compromised or non-compliant device from spreading malware or violating policies. References :=

Zero Trust Architecture (ZTA) is a security model that follows the philosophy of “never trust, always verify” and does not assume any implicit trust for any entity within or outside the network perimeter. ZTA is based on a set of core principles that guide its implementation and operation. According to the NIST SP 800-207, the three core principles of ZTA are:

A. Verify and authenticate. This principle emphasizes the importance of strong identification and authentication for all types of principals, including users, devices, and machines. ZTA requires continuous verification of identities and authentication status throughout a session, ideally on each request. It does not rely solely on traditional network location or controls. This includes implementing modern strong multi-factor authentication (MFA) and evaluating additional environmental and contextual signals during authentication processes.

D. Least privilege access. This principle involves granting principals the minimum level of access required to perform their tasks. By adopting the principle of least privilege access, organizations can enforce granular access controls, so that principals have access only to the resources necessary to fulfill their roles and responsibilities. This includes implementing just-in-time access provisioning, role-based access controls (RBAC), and regular access reviews to minimize the surface area and the risk of unauthorized access.

E. Assume breach. This principle assumes that the network is always compromised and that attackers can exploit any vulnerability or weakness. Therefore, ZTA adopts a proactive and defensive posture that aims to prevent, detect, and respond to threats in real-time. This includes implementing micro-segmentation, end-to-end encryption, and continuous monitoring and analytics to restrict unnecessary pathways, protect sensitive data, and identify anomalies and potential security events.

 Based on the exhibit, the true statements about the hr endpoint are:

• B. The endpoint is marked as a rogue device: The "w" symbol typically indicates a warning or an at-risk status, which can be associated with an endpoint being marked as rogue due to failing to meet the security compliance requirements or other reasons.
• C. The endpoint has failed the compliance scan: The "w" symbol can also signify that the endpoint has failed a compliance scan, which is a common reason for an endpoint to be marked as at risk.

To create a separate web filtering profile for off-fabric and on-fabric clients and push it to managed FortiClient devices in FortiClient EMS, the feature can be enabled in:

• A. Endpoint Policy: This is where administrators can define and manage different policies for FortiClient endpoints. These policies can include settings for web filtering, which can be customized for on-fabric and off-fabric scenarios.

The other options do not directly relate to the creation and management of web filtering profiles:

• B. ZTNA Connection Rules: These rules are more focused on access control and do not deal directly with web filtering profiles.
• C. System Settings: This section typically includes overall system configurations rather than specific policy definitions.
• D. On-fabric Rule Sets: While important for on-fabric configurations, they don't directly deal with web filtering profiles.

FortiNAC uses a variety of methods to identify devices on the network, such as Vendor OUI, DHCP fingerprinting, and device profiling12. One of the supported communication methods that FortiNAC uses for initial device identification during discovery is SNMP (Simple Network Management Protocol)3. SNMP is a protocol that allows network devices to exchange information and monitor their status4. FortiNAC can use SNMP to read information from switches and routers, such as MAC addresses, IP addresses, VLANs, and port status3. SNMP can also be used to configure network devices and enforce policies4. References: 1: Identification | FortiNAC 9.4.0 - Fortinet Documentation 2: Device profiling process | FortiNAC8.3.0 | Fortinet Document Library 3: Using FortiNAC to identify medical devices - James Pratt 4: How does FortiNAC identify a new device on the network?

To trigger layer 2 polling on FortiNAC, the three methods are:

• A. Polling scripts: These are scripts configured within FortiNAC to actively poll the network at layer 2 to gather information about connected devices.
• C. Manual polling: This involves manually initiating a polling process from the FortiNAC interface to gather current network information.
• D. Scheduled tasks: Polling can be scheduled as regular tasks within FortiNAC, allowing for automated, periodic collection of network data.

The other options are not standard methods for layer 2 polling in FortiNAC:

• B. Link traps: These are more related to SNMP trap messages rather than layer 2 polling.
• E. Polling using API: While APIs are used for various integrations, they are not typically used for initiating layer 2 polling in FortiNAC.
