A security technician is tasked with hardening a fleet of newly provisioned Windows workstations prior to enterprise deployment. To minimize the attack surface and mitigate unauthorized lateral movement, the technician needs to configure local default accounts and execution policies according to security best practices. Which of the following configurations represents the most secure baseline implementation?

Cevabı ve açıklamayı göster

Cevap: Disable the built-in Guest account, rename the default Administrator account, and disable AutoRun/AutoPlay policies across all drives.

Cevap

The correct baseline implementation requires disabling the built-in Guest account, renaming the built-in Administrator account, and disabling AutoRun and AutoPlay for all drives.
Hardening a workstation image requires applying the principle of least functionality and reducing attack vectors. Disabling the default Guest account, renaming the default Administrator account (to obscure its RID 500 target), and turning off AutoRun/AutoPlay across all media drives are foundational security controls recommended by CompTIA security standards.

Adım Adım Çözüm

1
Audit built-in default accounts
Identify that default accounts like Guest and Administrator present known targets for automated attacks.
Hardening best practices require disabling unneeded default accounts and renaming active default administrative accounts to prevent well-known account exploitation.
2
Configure media execution policies
Disable AutoRun and AutoPlay features globally via Local Group Policy or Registry settings.
Prevent malicious code on connected USB drives or external media from executing automatically upon insertion.
3
Verify tool selection for policy enforcement
Use Computer Management / Local Security Policy (secpol.msc) or Group Policy (gpedit.msc) rather than basic status applets or log viewers.
Administrative security controls must be configured in dedicated management snap-ins.

Cevap

Degaussing pairs with sanitizing legacy magnetic HDDs or tape media; ATA Secure Erase pairs with sanitizing functional NVMe or SATA SSDs for reuse; Cryptographic Erase pairs with sanitizing Self-Encrypting Drives (SEDs) via key destruction; Physical Shredding pairs with disposing of non-functional SSDs.
Each disposal method matches specific physical media traits and hardware goals: Degaussing neutralizes magnetic tracks on HDDs/tapes; ATA Secure Erase uses controller commands to wipe flash blocks on working SSDs for redeployment; Cryptographic Erase zeroizes encryption keys on SEDs; Physical Shredding mechanically destroys damaged flash hardware.

Adım Adım Çözüm

1
Analyze underlying storage architecture (magnetic vs. flash vs. encrypted)
Identify that magnetic media (HDDs/tapes) respond to electromagnetic fields, whereas flash drives (SSDs/NVMe) consist of solid-state ICs, and SEDs rely on onboard encryption keys.
Selecting an improper technique, such as degaussing an SSD, fails to sanitize the drive.
2
Evaluate hardware lifecycle intent (re-use vs. total physical destruction)
Functional drives scheduled for reuse require non-destructive firmware purging (ATA Secure Erase), while damaged or end-of-life drives require mechanical destruction (shredding).
Physical destruction renders hardware unusable for future deployment, whereas logical formats are required for drive repurposing.
3
Match specialized crypto-sanitization mechanisms
Destroying the key on a Self-Encrypting Drive (SED) instantly invalidates all stored ciphertext without reading or writing every sector.
Cryptographic Erase relies on hardware-level encryption key destruction for instant, secure drive decommissioning.

Cevap

The correct sequence for magnetic backup tape disposal is: 1) Log the serial numbers in the inventory tracking system, 2) Expose the magnetic tapes to an industrial degausser, 3) Place the degaussed tapes into a locked, tamper-evident container for transport, and 4) Obtain and archive a signed Certificate of Destruction.
Establishing a secure data disposal workflow requires serial number logging first to record asset custody. Next, degaussing purges the magnetic tape data on-site. Securing the media in locked containers preserves physical security during vendor transport. Finally, once physical shredding occurs, receiving the Certificate of Destruction completes regulatory compliance reporting.

Adım Adım Çözüm

1
Inventory and document media
Record unique tape serial numbers in the decommission log.
Comprehensive logging ensures full accountability and establishes an unbroken chain of custody before handling begins.
2
Perform initial logical data purging
Degauss the magnetic tapes on-site.
Degaussing disrupts the magnetic fields on magnetic tapes, erasing data on-site so unencrypted information is never exposed during transit.
3
Secure media for transport
Seal degaussed media in locked, tamper-evident transfer containers.
Physical security controls during transport prevent loss, theft, or unauthorized access while en route to shredding.
4
Verify and archive completion documentation
Receive and log the vendor-issued Certificate of Destruction.
The signed Certificate of Destruction serves as compliance proof that media lifecycle management requirements were satisfied.

Cevap

The correct procedural order is: first disable or rename default accounts and provision secured local accounts, second configure local account security policies (lockout and complexity), third disable unnecessary system services and features (AutoRun/AutoPlay), fourth configure Windows Defender Firewall and port restrictions, and fifth enable full-disk encryption (BitLocker) and screen lock policies.
Hardening a new workstation follows a logical defense-in-depth sequence: establishing strict local access control (account renaming/disabling), defining credential policies (lockout/complexity), minimizing software attack surface (disabling services/AutoRun), controlling network exposure (host firewall/ports), and finally applying physical and storage safeguards (BitLocker and screensaver locks).

Adım Adım Çözüm

1
Secure local user and administrator accounts
Default administrative pathways and Guest accounts are restricted or renamed, establishing baseline access control.
Before applying system-wide policies, control over account privileges must be established so default credentials cannot bypass configuration.
2
Enforce Local Security Policy baseline rules
Account lockout thresholds and password complexity criteria are activated via secpol.msc.
Establishing policy bounds on accounts protects the system against brute-force attempts during remaining configuration tasks.
3
Reduce attack surface by disabling unneeded services and features
Unused OS services, background apps, and removable media features like AutoPlay/AutoRun are turned off.
Eliminating unnecessary background features mitigates local and media-borne software vulnerabilities.
4
Restrict network boundaries via host firewall settings
Inbound and outbound network rules block unauthorized protocols and ports.
Network filtering ensures that remaining services do not expose unexpected network ports before network connection.
5
Implement data-at-rest and physical session security controls
BitLocker encrypts system drives and password-protected screensavers lock unattended sessions.
Storage encryption and inactivity timeouts complete the hardening baseline to guard against physical loss or unauthorized local access.

Which of the following statements best evaluates the effectiveness of this proposed sanitization plan?

Cevabı ve açıklamayı göster

Cevap: Degaussing will successfully sanitize the magnetic tapes and HDDs by disrupting their magnetic domains, but it will leave data completely intact on the NVMe SSDs because flash storage is unaffected by magnetic fields.

Cevap

Degaussing will successfully sanitize the magnetic tapes and HDDs by disrupting their magnetic domains, but it will leave data completely intact on the NVMe SSDs because flash storage is unaffected by magnetic fields.
Degaussing exposes magnetic storage media—such as hard disk drives and magnetic tapes—to a strong magnetic field, which disrupts the magnetic alignment of stored bits and renders the data completely unrecoverable. However, NVMe solid-state drives rely on flash memory microchips that store data via electrical charges inside floating-gate transistors. Because flash drives contain no magnetic components, degaussing leaves all data on the SSDs completely intact and fully accessible.

Adım Adım Çözüm

1
Categorize the media types present in the decommissioning project by their underlying storage technology.
Magnetic tapes and HDDs use magnetic storage tracks; NVMe SSDs use non-volatile flash memory (semiconductor circuit technology).
Data sanitization tools act differently based on the physical properties of the storage medium.
2
Analyze the physical mechanism of degaussing.
Degaussing generates a high-energy magnetic field that neutralizes and randomizes the magnetic alignments on magnetic media, permanently destroying data and internal drive timing tracks.
Determines which media types can be rendered unrecoverable via electromagnetic demagnetization.
3
Evaluate the impact of degaussing on solid-state (flash) storage.
Because SSDs retain data through trapped electrical charges in transistor gates rather than magnetic fields, degaussing has zero sanitization effect on NVMe SSDs.
Identifies why the technician's single-pass degaussing plan fails compliance requirements for flash-based drives, requiring alternative methods such as physical shredding, cryptographic erasure, or specialized software purge commands (e.g., NVMe Sanitize).

Cevap: Executing an ATA Secure Erase command using vendor drive utility software

Cevap

Executing an ATA Secure Erase command using vendor drive utility software.
Executing an ATA Secure Erase command using the drive manufacturer's utility software sends a voltage burst across all flash memory cells, effectively purging all stored data across all NAND blocks (including unallocated and over-provisioned areas). This method renders data completely unrecoverable while leaving the SSD physically intact and ready for reuse.

Adım Adım Çözüm

1
Analyze the media type and operational requirements.
The target devices are solid-state drives (SSDs) that must be rendered data-secure while preserving full physical functionality for donation.
Sanitization requirements differ between magnetic media and non-volatile NAND flash storage.
2
Evaluate sanitization methods against the security policy and hardware reuse constraint.
ATA Secure Erase applies a voltage pulse to flush all NAND blocks simultaneously, purging data across accessible and over-provisioned regions.
Methods like physical destruction prevent drive reuse, while degaussing is ineffective on flash chips and standard OS formatting leaves residual data recoverable.
3
Select the appropriate vendor utility command.
Use manufacturer-provided storage software to run ATA Secure Erase on each drive.
This satisfies compliance standards for data purging on SSDs without causing physical harm to the drive hardware.

The technician should set 'User Account Control: Behavior of the elevation prompt for standard users' to 'Prompt for credentials' and set 'User Account Control: Switch to the secure desktop when prompting for elevation' to 'Disabled'.
Configuring the policy setting for standard user elevation behavior to prompt for credentials forces authentication when standard accounts attempt administrative tasks. Disabling the secure desktop switch policy prevents the screen from dimming while displaying UAC elevation prompts.

Adım Adım Çözüm

1
Identify the policy controlling standard user elevation prompts
Configuring 'User Account Control: Behavior of the elevation prompt for standard users' to 'Prompt for credentials' ensures standard users must authenticate with administrative credentials before executing elevated tasks.
Standard user accounts require explicit administrator authentication to proceed with privileged operations.
2
Identify the policy controlling the dimmed Secure Desktop feature
Disabling 'User Account Control: Switch to the secure desktop when prompting for elevation' allows prompts to appear directly on the interactive user desktop without darkening the background.

Cevap: Update local anti-malware definitions using an isolated media source or internal update server.; Boot into Safe Mode or an isolated pre-installation environment to perform a full system anti-malware scan.

Cevap

Updating anti-malware definitions from a clean source and performing a full scan in Safe Mode or a clean pre-boot environment are the correct remediation actions.
Updating anti-malware signatures from a trusted offline or internal source and executing scans in Safe Mode or a pre-installation environment represent the key tasks of Step 4 (Remediate infected systems) in the CompTIA 7-step process. Safe Mode prevents rootkits and trojans from locking system resources during removal.

Adım Adım Çözüm

1
Identify the current step in the CompTIA 7-step malware removal workflow.
The technician has already completed Step 1 (Identify malware symptoms), Step 2 (Quarantine infected systems), and Step 3 (Disable System Restore). Step 4 is Remediate Infected Systems.
The process must follow the strict standard sequence.
2
Select appropriate actions for Step 4 (Remediate infected systems).
Step 4 requires updating signature files/engines from an uncompromised location and running anti-malware tools (often in Safe Mode or a pre-boot environment to bypass active rootkits).
Rootkits hook OS APIs when running normally, making pre-boot or Safe Mode scanning mandatory for thorough detection and removal.
3
Evaluate distractors against the 7-step process and tool capabilities.
Re-enabling System Restore prematurely violates Step 6 rules, and Event Viewer cannot quarantine files.
System Restore is only re-enabled after infection removal is verified, and log viewers are passive tools.

Cevap: Remote wipe capability to sanitize device storage over the network; Full device encryption paired with a mandatory passcode lock

Cevap

Enforcing remote wipe capability and full device encryption paired with a mandatory passcode lock.
Enforcing remote wipe allows administrators to send a signal to erase sensitive corporate information from a lost device. Full device encryption combined with a mandatory passcode lock secures data at rest so that even if an unauthorized user physically possesses the hardware, they cannot read the contents of the storage drive.

Adım Adım Çözüm

1
Identify the primary threat presented in the scenario.
The threat is unauthorized access to sensitive corporate data on a physically lost or stolen mobile device.
Physical control of the device has been lost, exposing stored files.
2
Evaluate security controls that safeguard local data on missing hardware.
Full device encryption paired with a passcode prevents offline or local data extraction, while remote wipe allows sanitizing the drive if the device cannot be recovered.
These controls combine at-rest encryption and remotely triggered sanitization to prevent data exposure.
