A network technician is configuring networking equipment inside an intermediate distribution frame (IDF) room shared with third-party facility contractors. Although the room itself requires keycard access, several unassigned Ethernet switch ports on the rack remain exposed, creating a risk of unauthorized physical connection to the internal network. Which of the following physical security controls should the technician implement to directly prevent unauthorized network cable insertions into these exposed ports?

Cevabı ve açıklamayı göster

Cevap: Physical port locks

Cevap

Physical port locks are the correct choice because they physically block unused RJ-45 switch ports from unauthorized network connections.
Physical port locks (such as RJ-45 port blockers) fit directly into open networking ports and require a specific key to remove. This prevents unauthorized users from physically connecting rogue devices or network cables into the switch.

Adım Adım Çözüm

1
Analyze the physical security vulnerability described in the scenario.
Unused Ethernet switch ports in a shared room are physically accessible and vulnerable to unauthorized device connections.
Identify the precise physical threat vector (unauthorized wired connection to network switch interfaces).
2
Evaluate the controls against the requirement to secure individual interface ports.
Physical port locks prevent network cables or hardware dongles from being inserted into RJ-45 or USB interfaces without a specialized removal key.
Port locks provide granular interface-level protection when general room access cannot completely eliminate unauthorized personnel presence.

A network support technician is assisting a user remotely on a Windows 11 Professional workstation. Whenever the user attempts an operation requiring administrative privileges, the technician's remote control software displays a blank black screen instead of showing the User Account Control (UAC) elevation prompt, preventing the technician from typing administrative credentials. Which Local Security Policy setting should be disabled to allow remote viewing of UAC prompts without completely turning off UAC?

Cevabı ve açıklamayı göster

Cevap: User Account Control: Switch to the secure desktop when prompting for elevation

Cevap

Disabling the security policy 'User Account Control: Switch to the secure desktop when prompting for elevation' prevents UAC from switching to an isolated desktop instance that blocks unprivileged remote desktop utilities from capturing the prompt screen.
The option selecting 'User Account Control: Switch to the secure desktop when prompting for elevation' is correct because the secure desktop isolates the screen to prevent software spoofing. Third-party remote tools without specialized service hooks cannot render the secure desktop, resulting in a black screen. Disabling this specific setting forces UAC prompts to appear on the standard desktop where remote software can capture them.

Adım Adım Çözüm

1
Identify the cause of the black screen during remote administration.
The secure desktop feature runs UAC prompts in a isolated system process space (Desktop context) that standard user-mode remote control agents cannot capture or render.
By default, Windows switches to the secure desktop to isolate elevation prompts from malicious software running on the user's interactive desktop.
2
Locate the targeted Local Security Policy rule in secpol.msc under Security Options.
Identify 'User Account Control: Switch to the secure desktop when prompting for elevation'.
This policy explicitly governs whether elevation prompts execute on the secure desktop or the user's interactive desktop.
3
Disable the secure desktop policy setting.
Prompts display on the standard user desktop, making them visible to the remote technician while preserving mandatory UAC credential requests.
This maintains elevation prompt requirements while resolving the remote capture conflict.

Cevap: Perform a Cryptographic Erase (Crypto-Erase) using the drive vendor's management utility to erase the Media Encryption Key.

Cevap

Cryptographic Erase (Crypto-Erase) using the drive vendor's management utility to erase the Media Encryption Key
Performing a Cryptographic Erase (Crypto-Erase) on Self-Encrypting Drives (SEDs) erases or resets the internal Media Encryption Key (MEK). Because all data written to an SED is encrypted at the hardware level, deleting the encryption key makes the existing data instantly and permanently unrecoverable, while resetting the drive to a usable factory state for safe redeployment.

Adım Adım Çözüm

1
Analyze the media type and operational requirements
Identified Self-Encrypting Drives (SEDs) containing confidential data that must be sanitized while preserving hardware functionality for redeployment.
Selection of data disposal methods depends on drive technology (SED/SSD vs. magnetic HDD) and whether the media is destined for reuse or physical destruction.
2
Evaluate sanitization mechanisms compatible with SED reuse
Cryptographic Erase (Crypto-Erase) invalidates or changes the drive's internal Media Encryption Key (MEK).
Without the original encryption key, all stored data blocks become permanent ciphertext (unrecoverable), allowing immediate drive reuse without physical damage.
3
Eliminate inappropriate disposal methods
Degaussing and shredding destroy hardware functionality, while standard OS formatting leaves wear-leveled/over-provisioned blocks intact.
Proper security compliance requires matching sanitization depth with hardware lifecycle goals.

Cevap

The hardening requirements map directly to their corresponding controls: prohibiting USB mass storage while retaining human interface devices corresponds to configuring Removable Storage Access policies in GPO; protecting LSASS from memory scraping corresponds to enabling Credential Guard with VBS; automatically locking an unattended desktop via Bluetooth proximity corresponds to Dynamic Lock; and disabling automated code launch from inserted media corresponds to disabling AutoPlay and AutoRun policies.
Each security requirement aligns with its specific technical implementation. Denying USB storage access while preserving keyboards/mice relies on GPO Removable Storage Access restrictions. Protecting LSASS memory from administrative privilege abuse requires Credential Guard with VBS. Proximity-based session locking uses Bluetooth Dynamic Lock. Preventing automatic binary launch on volume mount is accomplished by disabling AutoPlay and AutoRun.

Adım Adım Çözüm

1
Analyze USB mass storage blocking requirements vs peripheral functionality
Disabling device driver installation entirely would break mice and keyboards. Removable Storage Access GPOs target specific device classes, denying storage access while leaving HIDs operational.
Granular policy enforcement allows administrators to restrict removable storage without impairing standard USB input peripherals.
2
Analyze LSASS memory protection techniques
Standard access control lists do not stop elevated processes from reading LSASS memory. Credential Guard employs Virtualization-based Security (VBS) to isolate LSASS tokens outside the standard OS kernel.
VBS isolates secrets in a hardware-secured environment, rendering memory scraping tools ineffective even when running with administrative rights.
3
Evaluate automated physical walk-away locking options
Dynamic Lock uses paired Bluetooth device RSSI signal attenuation to detect user absence and trigger a lock command.
This provides defense-in-depth for physical security when users fail to manually lock their desktops.
4
Evaluate automatic media execution controls
Disabling AutoPlay and AutoRun globally stops automatic parsing and launching of scripts or binaries embedded in newly inserted media.
AutoRun and AutoPlay policies directly govern automatic file handler triggers upon drive volume mounting.

An IT security administrator is preparing to return a leased enterprise storage array shelf populated with flash-based NVMe solid-state drives (SSDs) containing confidential financial records. According to organizational compliance policy, all storage media must be sanitized to the NIST SP 800-88 'Purge' standard before transfer. Additionally, the lease contract stipulates that the physical drives must remain fully functional and undamaged upon return to avoid severe financial penalties. Which of the following data disposal actions should the administrator perform to satisfy both constraints?

Cevabı ve açıklamayı göster

Cevap: Perform an NVMe Sanitize block erase or cryptographic erasure command directly via the drive controller firmware.

Cevap

Execute an NVMe Sanitize block erase or cryptographic erasure command directly via the drive controller firmware.
Executing a controller-level NVMe Sanitize command (such as block erase or cryptographic erasure on self-encrypting drives) instructs the drive controller to purge all physical NAND flash cells, including over-provisioned space and wear-leveling areas. This fulfills the NIST SP 800-88 'Purge' compliance standard while leaving the physical storage drive functional for return under the lease agreement.

Adım Adım Çözüm

1
Analyze the dual requirements of the scenario.
Identified two constraints: 1) Data sanitization level must meet NIST SP 800-88 'Purge' (infeasible laboratory recovery); 2) Physical drives must remain functional to avoid lease penalties.
Choosing a destruction or sanitization method depends on both security compliance level and physical hardware retention requirements.
2
Evaluate candidate sanitization techniques against flash-based NVMe SSD media characteristics.
Degaussing is ineffective for solid-state storage. Physical shredding violates the lease return policy. OS-level zero-fill formatting only meets the 'Clear' standard because wear-leveling algorithms prevent access to hidden over-provisioned blocks.
Solid-state drives manage data layout internally through a Flash Translation Layer (FTL), requiring firmware-level execution to reach all physical NAND cells.
3
Select the correct firmware-level sanitization command.
NVMe Sanitize (block erase / crypto erase) instructs the SSD controller to erase all physical blocks, including over-provisioned space, meeting the 'Purge' standard while preserving drive operational integrity.

Cevap

Containerization matches with isolating corporate data from personal data. Remote Wipe matches with remotely erasing sensitive company information. Geofencing matches with using location services to enforce security policies. Sideloading matches with installing applications from sources outside official app stores.
Each feature corresponds to its specific mobile device management function: Containerization provides storage separation, Remote Wipe provides loss response security, Geofencing provides location-aware security rules, and Sideloading represents untrusted application installation.

2
Identify the primary function of Remote Wipe.
Matches with remotely erasing sensitive company information or restoring factory settings.
Remote wipe prevents data breaches when mobile hardware is lost or stolen.
3
Identify the primary function of Geofencing.
Matches with using location services to enforce security policies based on physical boundaries.
Geofencing dynamically enables or disables features depending on geographical coordinates.
4
Identify the definition of Sideloading.
Matches with installing applications directly from sources outside official app stores.
