During network monitoring, a security team identifies an unauthorized device acting as a rogue DHCP server on a corporate office VLAN, assigning malicious default gateway addresses to internal endpoints. The incident response team has confirmed the alert and identified the specific physical switch port connected to the rogue device. According to standard incident response procedures, which of the following actions should the team perform next?

Cevabı ve açıklamayı göster

Cevap: Shut down the identified switch port to isolate the rogue device from the localized network segment.

Cevap

Shut down the identified switch port to isolate the rogue device from the localized network segment.
In accordance with standard incident response frameworks (such as NIST SP 800-61), after detecting and analyzing an active threat, the immediate priority is Containment. Disabling the switch port connected to the rogue DHCP server immediately prevents the unauthorized device from sending additional malicious network configurations to clients.

Adım Adım Çözüm

1
Analyze the current phase in the incident response lifecycle based on the scenario context.
The incident team has already detected and analyzed the incident, confirming the presence and physical location of the rogue DHCP server.
According to the NIST SP 800-61 IR framework, once an active incident is detected and identified, the immediate next phase is Containment.
2
Evaluate the proposed response actions against containment objectives.
Disabling the specific switch port stops the rogue DHCP server from issuing further unauthorized leases without shutting down unrelated network segments.
Effective containment isolates the threat immediately to prevent further damage while preserving operational stability.
3
Distinguish containment steps from out-of-order eradication, forensic, or detective steps.
Actions such as host re-imaging (eradication/recovery) or creating monitoring rules (detection/prevention) must not supersede active containment.
Following proper IR phase sequencing ensures active risks are neutralized before remediation and long-term improvements begin.

Soru 1542Soru

A security operations analyst is reviewing access gateway logs following reports that remote workers cannot connect to an enterprise VPN. The authentication gateway delegates identity verification to a central SAML 2.0 Identity Provider (IdP) and passes authorization queries to a RADIUS policy server. The analyst inspects the following log entries from the RADIUS policy engine:

[2026-07-27 11:02:14] RADIUS-AUTH: SAML token validated successfully for '[email protected]'.
[2026-07-27 11:02:15] RADIUS-POL: Evaluating Network Policy 'VPN_Engineering_Access'.
[2026-07-27 11:02:15] RADIUS-POL-ERR: Group attribute 'CN=Contractors,OU=Groups' does not match required group 'CN=FullTime_Engineers'.
[2026-07-27 11:02:15] RADIUS-AAA: Sending ACCESS-REJECT for session candidate '[email protected]'.

Based on the log output, which of the following best describes the root cause of the access failure?

Cevabı ve açıklamayı göster

Cevap: Authentication succeeded at the IdP, but authorization failed at the RADIUS policy server due to mismatched group membership attributes.

Cevap

Authentication succeeded at the IdP, but authorization failed at the RADIUS policy server due to mismatched group membership attributes.
The log analysis demonstrates a clear separation between AAA functions. The initial SAML token validation confirms identity verification (authentication) succeeded. However, subsequent policy evaluation against the user's LDAP group attributes failed because the user is listed under 'Contractors' while the target policy requires 'FullTime_Engineers'. Consequently, authorization failed, leading to the RADIUS ACCESS-REJECT response.

Adım Adım Çözüm

1
Analyze the log entries chronologically to separate AAA steps.
The entry at 11:02:14 confirms 'SAML token validated successfully', demonstrating successful identity verification (authentication).
SAML token validation completes the authentication phase of AAA.
2
Evaluate the error event at 11:02:15.
The policy engine reports that 'CN=Contractors' does not match 'CN=FullTime_Engineers'.
This check determines what permissions and resources the authenticated user is allowed to access (authorization phase).
3
Determine the root cause of the ACCESS-REJECT response.
The user was rejected during the authorization phase because their active group attribute did not meet the requirement of the 'VPN_Engineering_Access' policy.
Failing policy criteria triggers an ACCESS-REJECT packet even after successful primary authentication.

A security analyst is investigating an authentication and privileges alert in a hybrid enterprise environment. The log audit reveals that a non-interactive service account (`svc_vaultsync`) authenticated via LDAPS from a workstation IP address and successfully retrieved domain administrative credentials from a Privileged Access Management (PAM) vault outside scheduled maintenance hours. Which of the following operational controls or administrative practices should the security team implement to mitigate this incident and harden IAM operations against future abuse? (Select TWO.)

Cevabı ve açıklamayı göster

Cevap: Configure service accounts to use Group Managed Service Accounts (gMSAs) with auto-rotating passwords and disable interactive shell login capabilities.; Enforce Just-In-Time (JIT) access workflows requiring approval before PAM vault administrative credentials can be checked out.

Cevap

The correct operational measures are configuring Group Managed Service Accounts (gMSAs) with disabled interactive logins, and enforcing Just-In-Time (JIT) PAM checkout approval workflows.
Configuring Group Managed Service Accounts (gMSAs) with automatic password management and non-interactive privileges prevents manual checkout or misuse of service account credentials. Enforcing Just-In-Time (JIT) access requiring explicit approvals ensures privileged credentials cannot be retrieved from a PAM vault without prior authorization.

Adım Adım Çözüm

1
Analyze the incident details from the log audit.
Identified that a service account was used interactively outside maintenance windows to check out domain admin credentials from a PAM vault.
Determining how the service account was abused identifies the weakness in account lifecycle management and PAM checkout rules.
2
Evaluate identity lifecycle and service account security controls.
Converting service accounts to gMSAs removes password exposure and prevents interactive logon capabilities.
Service accounts should be non-interactive and managed dynamically by Active Directory to eliminate static credential theft.
3
Evaluate Privileged Access Management (PAM) operational controls.
Requiring Just-In-Time (JIT) approval workflows prevents unauthorized credential checkout outside approved change windows.
JIT access ensures elevated credentials are only provisioned temporarily and upon explicit manager/peer authorization.

During a scheduled vulnerability assessment of an enterprise network segment, an automated scanner causes several legacy network switches to become unresponsive due to resource exhaustion from high-frequency port probing and service discovery requests. Which of the following adjustments should the security engineer implement to maintain visibility into these network devices without causing service disruptions?

Cevabı ve açıklamayı göster

Cevap: Reduce the scan throttle rate and switch to a non-intrusive scan profile for the affected network segment.

Cevap

Reduce the scan throttle rate and switch to a non-intrusive scan profile for the affected network segment.
Reducing the scan intensity (throttling) and switching to non-intrusive scan settings prevents resource exhaustion on sensitive hardware while allowing the scanner to gather essential service and version information safely.

Adım Adım Çözüm

1
Identify the cause of system disruption during the assessment.
Aggressive, high-frequency port probes and intrusive checks exhausted the processing capacity of legacy switches.
Legacy network equipment often has limited CPU and memory buffers that cannot handle rapid connection requests.
2
Evaluate potential scan configuration changes to mitigate operational impact.
Adjusting scan speed (throttling) and disabling intrusive service exploitation tests prevents denial-of-service conditions.
Non-intrusive scans test for vulnerability signatures without executing aggressive payloads or overwhelming sockets.

Cevap

Automated NAC dynamic blocking corresponds to Technical / Preventive; Mandatory onboarding policies and agreements correspond to Managerial / Directive; Biometric mantrap vestibules correspond to Physical / Preventive; Out-of-band NIDS monitoring corresponds to Technical / Detective.
Each control measure accurately aligns across both axes: Automated NAC health checks use technological mechanisms to block non-compliant endpoints (Technical / Preventive). Corporate onboarding policies and acceptable use agreements set rules for human behavior through management governance (Managerial / Directive). Biometric mantrap vestibules physically stop unauthorized individuals from entering facility spaces (Physical / Preventive). Out-of-band NIDS sensors use monitoring software to inspect mirrored network traffic and alert on security anomalies without inline blocking (Technical / Detective).

Adım Adım Çözüm

1
Determine the primary category for each mechanism based on how it is implemented.
NAC health checking and out-of-band NIDS monitoring rely on hardware/software systems (Technical). Training mandates and acceptable use agreements stem from management oversight and policy frameworks (Managerial). Mantraps rely on physical structures and access barriers (Physical).
Control categories differentiate whether controls are implemented via technology, administrative management, operational procedures, or physical security boundaries.
2
Determine the functional type for each mechanism based on its operational objective during an event.
Blocking non-compliant endpoints and physically stopping tailgating/unauthorized access prevent security incidents before occurrence (Preventive). Mandating behavior directs human actions to comply with organizational expectations (Directive). Identifying anomalous traffic and triggering alerts discovers active or past events (Detective).
Functional types define the specific role a security control plays in the timeline of a threat or security event.
3
Synthesize category and functional type classifications into pair assignments.
Match NAC to Technical / Preventive, onboarding mandates to Managerial / Directive, mantrap to Physical / Preventive, and out-of-band NIDS to Technical / Detective.

Cevap: Remotely isolating the host from the network via agent-based controls to halt lateral movement while preserving management connectivity.; Recording continuously generated process lineage, file modification, and registry access telemetry for historical analysis.

Cevap

The core capabilities of an Endpoint Detection and Response (EDR) platform in this scenario are isolating the host from the network at the software agent layer and recording continuous process, file, and registry telemetry.
Endpoint Detection and Response (EDR) tools emphasize host-level containment and real-time behavioral visibility. Agent-based network isolation immediately stops an active threat from spreading laterally across the enterprise while preserving administrative control. Additionally, EDR provides continuous telemetry recording (such as process trees, memory calls, and file activities) necessary for thorough post-incident analysis.

Adım Adım Çözüm

1
Identify the immediate containment capability required for a compromised endpoint.
Host network isolation implemented by the EDR agent prevents malicious lateral movement without requiring physical network disconnects.
Containment must occur quickly at the endpoint level to stop network spread while maintaining administrative access.
2
Determine the investigative data collection function characteristic of EDR.
Continuous behavioral logging and process lineage telemetry allow analysts to reconstruct attack sequences.
EDR solutions record detailed historical telemetry rather than relying solely on point-in-time file scans.

During a security incident, an organization's Security Operations Center (SOC) identifies a compromised containerized application actively scanning internal microservices for vulnerabilities. Place the following incident response actions in the correct sequential order from FIRST to LAST according to standard incident handling frameworks.

Öğeleri doğru sıraya koymak için sürükleyin

Cevabı ve açıklamayı göster

Cevap

The correct order of incident response actions is: 1) Isolate the compromised container using microsegmentation network policies; 2) Capture volatile memory artifacts and container runtime logs; 3) Terminate the compromised container instance and redeploy from a verified clean image; 4) Restore normal production routing while monitoring network telemetry; 5) Conduct a post-mortem review to update container security controls.
Standard incident handling frameworks (such as NIST SP 800-61) follow a strict lifecycle order: Containment (isolating network traffic) occurs first to stop active damage; Evidence Preservation collects volatile forensic artifacts before system modification; Eradication removes the root cause by destroying the compromised instance and deploying a trusted build; Recovery restores production operations under enhanced monitoring; Post-incident Activity reviews performance and updates playbooks to enhance future resiliency.

Adım Adım Çözüm

1
Determine the Containment Step
Network isolation via microsegmentation is placed first.
Immediate containment stops active lateral movement and limits incident scope before any destructive or disruptive changes are made.
2
Determine the Evidence Preservation Step
Volatile memory and log collection is placed second.
Evidence preservation must happen while the system remains isolated but before deleting or rebuilding the container instance.
3
Determine the Eradication Step
Termination of the container and redeployment from a clean image is placed third.
Eradication removes the threat vectors and compromised binaries once evidence has been secured.
4
Determine the Recovery Step
Restoring traffic with active telemetry monitoring is placed fourth.
Recovery brings systems safely back into full production under close monitoring to confirm stability.
5
Determine the Lessons Learned Step
Post-mortem review and CI/CD security updates are placed fifth.
Post-incident analysis evaluates the incident response effort after operational restoration to prevent future recurrence.

Credentialed Scanning matches authenticated administrative system inspection; Non-Credentialed Scanning matches unauthenticated network service discovery; Passive Monitoring matches non-intrusive SPAN port traffic analysis; Agent-Based Assessment matches continuous endpoint monitoring independent of network location.
Each vulnerability assessment method fulfills a specific operational requirement based on access privileges, network placement, and traffic tolerance. Credentialed scanning provides in-depth host visibility through authentication; non-credentialed scanning measures unauthenticated perimeter exposure; passive monitoring provides zero-impact traffic observation via SPAN/TAP; and agent-based scanning provides continuous host inspection for off-network endpoints.

Adım Adım Çözüm

1
Analyze the access perspective of Credentialed vs. Non-Credentialed scanning.
Credentialed scanning accesses internal OS parameters via login credentials to reduce false positives, matching right_1. Non-credentialed scanning examines exposed network ports without credentials, matching right_2.
Authenticating directly allows scanners to query internal package managers and registries directly, whereas unauthenticated scans only see externally exposed services.
2
Evaluate the traffic impact of Passive Vulnerability Monitoring.
Passive monitoring observes mirrored traffic (SPAN/TAP) without generating probe traffic, matching right_3.
Sensitive industrial control systems or operational technology environments require zero active probe traffic to prevent service disruption.
3
Examine the operational scope of Agent-Based Vulnerability Assessment.
Local agents collect local system data continuously and report back when connected, matching right_4.
Mobile or remote laptops frequently move off-premise, making active network scans ineffective compared to host-installed software agents.

Which of the following Endpoint Detection and Response (EDR) actions should the analyst take?

Cevabı ve açıklamayı göster

Cevap: Initiate host network isolation through the EDR console agent

Cevap

Initiate host network isolation through the EDR console agent
The correct action is to initiate host network isolation via the EDR agent console. Host isolation blocks network adapter communication to restrict lateral movement across the enterprise while preserving the EDR agent's control link so SOC analysts can maintain remote command capabilities and capture volatile system memory.

A financial institution upgraded its treasury management software to require biometric verification prior to executing wire transfers, while enforcing role-based policies that constrain transfer limits according to employee job titles. During a post-transaction audit, security analysts confirmed that user identities were successfully verified and authorization boundaries were strictly enforced, but noted that no timestamped system logs were generated to record the specific destination account numbers or transfer amounts modified during sessions. Which pillar of the AAA framework is incomplete in this system design?

Cevabı ve açıklamayı göster

Cevap: Accounting

Cevap

Accounting is the missing AAA pillar because the system fails to maintain timestamped audit logs of user actions and transaction details.
The correct answer is Accounting. The AAA framework consists of Authentication (verifying identity), Authorization (granting permissions), and Accounting (logging activity and auditing). In this scenario, identity verification and role-based privilege enforcement were performed, but recording transaction logs and specific data modifications was omitted, which directly falls under the Accounting pillar.

Adım Adım Çözüm

1
Evaluate the first AAA component (Authentication) against the scenario details.
Biometric verification successfully proves the identity of the user initiating the transaction, confirming authentication is present.
Authentication verifies identity before granting access.
2
Evaluate the second AAA component (Authorization) against the scenario details.
Role-based transfer limit enforcement ensures users operate within granted permission bounds, confirming authorization is present.
Authorization controls what resources and actions an authenticated identity can access.
3
Evaluate the third AAA component (Accounting) against the identified operational gap.
The absence of timestamped audit logs detailing modified account numbers and transfer amounts represents a lack of session logging and tracking.

The correct sequence is: 1) Generate an asymmetric key pair locally on the server; 2) Create a Certificate Signing Request (CSR) containing the public key and domain details; 3) Submit the CSR to the Certificate Authority (CA) for validation and signing; 4) Install the CA-signed digital certificate on the web server.
The standardized PKI certificate enrollment workflow requires local key pair generation first, followed by bundling the public key into a CSR, submitting the CSR to the CA for domain verification and signature, and finally binding the issued certificate to the web service.

Adım Adım Çözüm

1
Generate asymmetric key pair on the server
A public key and a protected private key are created.
The server must possess a private key before requesting a corresponding signed certificate.
2
Formulate Certificate Signing Request (CSR)
A CSR file containing the public key and organizational details is generated.
The CA requires the public key and domain identity details to construct the certificate body.
3
Submit CSR to Certificate Authority (CA)
The CA verifies domain control and issues a signed certificate.
Validation establishes trust before the CA applies its digital signature.
4
Install signed certificate on the server
The web server presents the valid CA-signed certificate during TLS handshakes.
Clients can now establish encrypted TLS sessions by verifying the certificate chain back to a trusted root CA.
