An IT technician is configuring legacy embedded environmental monitoring units throughout a datacenter facility. The embedded operating system on these units cannot host endpoint security agents, lacks native full-disk encryption capabilities, and cannot be enrolled in the enterprise Mobile Device Management (MDM) solution. To prevent unauthorized access and protect the core network from lateral movement if a monitor is compromised, which of the following is the BEST primary security measure to implement?

Cevabı ve açıklamayı göster

Cevap: Isolate the monitoring units on a dedicated network segment with restricted firewall access and replace all factory default administrative passwords.

Cevap

Isolate the monitoring units on a dedicated network segment with restricted firewall access and replace all factory default administrative passwords.
Embedded systems often have limited computing resources and static firmware, making them incapable of running traditional MDM software, anti-malware agents, or containerized applications. Securing these systems relies on network micro-segmentation (isolating them on dedicated VLANs with strict firewall ACLs) and disabling or updating default vendor administrative credentials to reduce exposure.

Adım Adım Çözüm

1
Analyze device limitations and security constraints.
Identified that embedded IoT devices lack agent support, encryption, and MDM compatibility.
Embedded systems frequently use specialized firmware or Real-Time Operating Systems (RTOS) that cannot run standard security tools.
2
Determine appropriate defense-in-depth controls for constrained devices.
Select network-level isolation (micro-segmentation/VLANs) and fundamental device hardening (credential changes).
Since internal agent-based security cannot be installed, network barriers and changing default credentials prevent unauthorized administrative login and lateral movement.

Which of the following security actions best accomplishes these hardening goals?

Cevabı ve açıklamayı göster

Cevap: Disable Link-Local Multicast Name Resolution (LLMNR) via Local Group Policy and stop/disable the Remote Registry service.

Cevap

The technician should disable Link-Local Multicast Name Resolution (LLMNR) via Local Group Policy and stop/disable the Remote Registry service.
Disabling Link-Local Multicast Name Resolution (LLMNR) prevents fall-back broadcast name resolution spoofing attacks, and disabling the Remote Registry service stops unauthorized users from reading or altering registry keys remotely. Together, these steps effectively reduce the network attack surface on standalone workstations.

Adım Adım Çözüm

1
Identify key attack vectors associated with legacy network resolution and unnecessary system services.
Recognize that LLMNR uses unauthenticated network broadcasts that attackers can spoof to capture credential hashes, while the Remote Registry service exposes registry modifications over the network.
Hardening requires reducing the system attack surface by turning off unneeded protocols and services.
2
Select the appropriate administrative controls to disable these components on standalone Windows endpoints.
Use Local Group Policy Editor (gpedit.msc) to disable turn off multicast name resolution, and Services (services.msc) to set Remote Registry startup type to Disabled.
This directly mitigates network spoofing and unauthorized remote registry access without restricting authorized local administrative management.

Cevabı ve açıklamayı göster

Cevap: WPA3-Enterprise using 802.1X authentication with AES encryption

Cevap

WPA3-Enterprise using 802.1X authentication with AES encryption is the correct configuration.
The configuration specifying WPA3-Enterprise with 802.1X authentication and AES encryption directly meets all specified requirements. Enterprise modes implement 802.1X port-based access control, requiring clients to authenticate against an authentication server (e.g., RADIUS) using their individual Active Directory credentials. Furthermore, WPA3 enforces strong AES-based encryption algorithms.

Adım Adım Çözüm

1
Identify the authentication requirement
Individual user logins via corporate Active Directory demand an Enterprise security mode using 802.1X and a RADIUS server, rather than a shared passphrase (Personal mode).
Personal modes (PSK/SAE) share one password across all client devices, preventing unique user identification and centralized access revocation.
2
Identify the encryption requirement
The requirement specifies AES encryption.
AES (used in CCMP/GCMP) provides strong, modern data protection, whereas TKIP is a legacy mechanism that is deprecated and insecure.
3
Combine requirements to select the correct wireless mode
WPA3-Enterprise with 802.1X and AES meets both individual authentication and strong encryption requirements.

Cevap: Physical shredding or disintegration of both HDDs and SSDs into tiny physical fragments; Exposing the magnetic hard disk drives to a high-capacity degausser

Cevap

Physical shredding of both drive types and degaussing the magnetic hard disk drives are valid data destruction methods.
Physical shredding or disintegration destroys the physical structure of both HDDs and SSDs, rendering data recovery impossible regardless of storage architecture. Degaussing subjects magnetic storage to a powerful magnetic field that disrupts magnetic domains, permanently destroying data on HDDs.

Identify the media types being decommissioned
The media consists of both magnetic HDDs (magnetic domain storage) and SSDs (flash memory electronic storage).
Different storage technologies require specific sanitization and destruction techniques.
2
Evaluate degaussing against magnetic vs solid-state media
Degaussing works on HDDs by destroying magnetic fields, but has no sanitization effect on non-magnetic SSD flash memory.
Degaussers disrupt magnetic domains; semiconductors do not store data magnetically.
3
Evaluate physical destruction across media types
Physical shredding or disintegration renders both magnetic platters and flash memory chips physically destroyed.

Cevap

1. Restricting mobile application functionality based on physical perimeter location matches with Geofencing.
2. Encapsulating corporate apps and data on BYOD devices matches with Containerization.
3. Preventing unauthorized binary execution on embedded devices matches with Application Whitelisting.
4. Verifying device security health before granting VPN access matches with Posture Assessment.
Each requirement directly aligns with its specific technical implementation:
- Location-driven security enforcement uses Geofencing.
- Segmenting corporate data from personal storage on BYOD endpoints utilizes Containerization.
- Restricting execution on resource-constrained embedded systems relies on Application Whitelisting.
- Evaluating endpoint health before establishing connection tunnels requires Posture Assessment.

Adım Adım Çözüm

1
Analyze location-based policy enforcement requirements for mobile devices.
Identify that using location services (GPS/cellular/Wi-Fi) to restrict app capabilities outside a physical boundary defines geofencing.
Geofencing dynamically alters device posture or application availability based on real-time location metrics.
2
Evaluate BYOD data isolation and selective wipe controls.
Identify containerization (MAM) as the technology designed to sandbox corporate assets from personal user storage.
Containerization ensures corporate privacy control while maintaining personal user privacy on non-corporate-owned hardware.
3
Determine execution control methods for embedded IoT hardware.
Match application whitelisting with embedded system binary execution control.
Embedded systems frequently lack compute resources for real-time signature antivirus scanning, making strict whitelisting the optimal default-deny mitigation.
4
Examine pre-connection health validation controls.
Associate checking patch levels and root status before VPN access with posture assessment.
Posture assessment ensures endpoints satisfy baseline health requirements prior to network connection authorization.
