Cevabı ve açıklamayı göster

Cevap

Passive Vulnerability Scanning corresponds to monitoring network traffic silently without probes. Credentialed Vulnerability Scanning corresponds to logging into target systems with valid accounts to audit configuration and patches. Dynamic Application Security Testing (DAST) corresponds to testing a running application by sending simulated malicious requests. Static Application Security Testing (SAST) corresponds to analyzing source code or binaries offline without code execution.
Each assessment method is paired according to its execution environment and access model: Passive scanning observes network traffic without active probing; Credentialed scanning uses valid host credentials for accurate internal assessment; DAST tests live applications at runtime; SAST analyzes unexecuted source code or binaries.

Adım Adım Çözüm

1
Differentiate network-level scanning approaches (passive vs. credentialed active).
Identify that non-intrusive traffic capture maps to passive scanning, while authenticated endpoint auditing maps to credentialed scanning.
Passive scanning relies on packet sniffing, whereas credentialed scanning logs into host operating systems.
2
Differentiate application security testing techniques (SAST vs. DAST).
Identify that SAST operates on source code/binaries statically before execution, whereas DAST operates dynamically on running web applications.
SAST requires access to code without running it, while DAST evaluates real-time HTTP requests and server responses during execution.

Eşleşmeler

Cevabı ve açıklamayı göster

Cevap

Under the cloud shared responsibility model: OS patching and host firewall configuration fall under Infrastructure as a Service (IaaS); application code and database schema management fall under Platform as a Service (PaaS); identity governance, access policies, and data classification in hosted applications fall under Software as a Service (SaaS); and stateless function logic with trigger permissions falls under Function as a Service (FaaS / Serverless).
Each deployment model dictates a different division of security controls between cloud service providers (CSPs) and enterprise tenants according to the cloud shared responsibility framework. Moving from IaaS to PaaS, SaaS, and FaaS progressively shifts infrastructure, OS, and runtime platform operational duties to the provider, while data governance and identity authorization remain customer responsibilities across all service models.

Adım Adım Çözüm

1
Analyze the scope of responsibility for guest operating systems and network firewalls.
Identify that managing OS patches and guest firewalls requires access at the OS abstraction layer, placing responsibility on the customer in IaaS.
IaaS provides raw compute resources where the provider handles physical and hypervisor layers, leaving OS administration to the tenant.
2
Evaluate the management boundary for database schema configurations and application code on managed platforms.
Determine that application logic and database schema permissions fall under PaaS customer responsibilities.
PaaS abstracts the underlying OS and database engine maintenance, allowing customers to focus on custom code and data schema security.
3
Assess enterprise user access control and data classification in hosted email applications.
Map hosted end-user application identity and data access controls to SaaS.
SaaS providers manage the entire application infrastructure, leaving only data access, identity management, and endpoint security to the customer.
4
Identify event-driven stateless function execution security responsibilities.
Match function logic and trigger configurations to FaaS / Serverless.
FaaS eliminates container and server administration for the customer, isolating their responsibility to the uploaded code and trigger events.

Cevap

Static Application Security Testing (SAST) pairs with inspecting source code at rest without execution. Dynamic Application Security Testing (DAST) pairs with testing live running applications from an external perspective. Credentialed Vulnerability Scanning pairs with using local system authentication rights to inventory patch levels. Passive Network Vulnerability Scanning pairs with non-intrusive traffic monitoring via SPAN or TAP interfaces.
Each testing method is paired with its defining operational characteristic: SAST analyzes unexecuted source code; DAST tests active applications dynamically; credentialed scanning authenticates locally to check internal patch levels; passive scanning sniffs network traffic non-intrusively without generating network probes.

Adım Adım Çözüm

1
Differentiate between static and dynamic application security testing approaches.
SAST operates on non-running source code or binaries early in the SDLC, whereas DAST requires a live running application to simulate runtime attacks.
SAST is a white-box code inspection technique, whereas DAST is a black-box runtime evaluation technique.
2
Differentiate between credentialed active scanning and passive network monitoring.
Credentialed scanning logs directly into operating systems to evaluate configuration state, while passive scanning observes packet flows via network TAPs/SPAN ports without sending traffic.
Credentialed scans minimize false positives by accessing internal host details, whereas passive scans avoid disrupting sensitive operational networks.

Each deception technology matches its specific deployment role: Honeytokens represent fake credentials or data elements; Honeynets constitute multi-host decoy network environments; Honeyfiles are audited decoy documents; and Breadcrumbs serve as endpoint lure artifacts that steer threat actors toward decoy assets.

Adım Adım Çözüm

1
Identify the data-centric deception element intended for credential/data harvesting detection.
Associate Honeytoken with fake credentials, database entries, or API keys embedded in production repositories.
Honeytokens focus specifically on monitoring unauthorized usage of non-production data values.
2
Differentiate macro-level network decoy environments from single-host artifacts.
Associate Honeynet with the complete simulated network segment containing multiple decoy systems.
Honeynets provide multi-system telemetry to observe broad attack vectors and lateral movement techniques.
3
Distinguish between monitored document files and endpoint redirection lures.
Associate Honeyfile with decoy documents stored on file shares, and Breadcrumb with host-level artifacts that direct attackers to honeypots.
Honeyfiles monitor data access directly, whereas breadcrumbs manipulate adversary reconnaissance paths on host systems.

Cevap

The 3DES TLS gateway matches the Sweet32 collision weakness; the identity provider key mismatch matches the algorithm confusion vulnerability; the IP subnet microservices restriction matches the implicit perimeter reliance defect; and the Root CA key on filesystem matches the insecure key management lacking HSM protection.
Each security weakness is mapped to its underlying technical vulnerability: 3DES CBC and SHA-1 suffer from collision flaws (Sweet32); JWT public key verification under HMAC leads to algorithm confusion forgery; IP-based microservice boundaries suffer from perimeter-reliance defects; and software filesystem storage of Root CA keys represents weak key management lacking HSM protection.

Adım Adım Çözüm

1
Analyze the cryptographic cipher flaws in the legacy TLS configuration.
Identify that 3DES uses 64-bit blocks vulnerable to Sweet32 collision attacks and SHA-1 is cryptographically broken.
64-bit block ciphers in CBC mode expose session keys to collision attacks after approximately 32 GB of data.
2
Evaluate the authentication token key misconfiguration.
Recognize key confusion where public keys are treated as symmetric secrets to forge signatures.
In algorithm confusion attacks (e.g., RS256 swapped to HS256), the receiver verifies an HMAC using the public key, enabling signature forgery.
3
Examine the network segment access control strategy for microservices.
Identify perimeter reliance and failure to enforce Zero Trust microsegmentation and mutual TLS (mTLS).
Subnet IP checks create implicit trust zones susceptible to IP spoofing and lateral movement.
4
Review the PKI root private key storage mechanism.
Classify software-based private key storage without hardware isolation as inadequate key protection.
Root CA private keys require specialized cryptographic hardware (HSMs) to prevent unauthorized exfiltration.

Cevap

Infrastructure as a Service (IaaS) matches physical hardware, facilities, core networking, and hypervisor virtualization layer; Platform as a Service (PaaS) matches underlying infrastructure, operating system, middleware, and application runtime environment; Software as a Service (SaaS) matches complete software application stack, application maintenance, platform, and underlying infrastructure.
Each cloud service model defines a distinct demarcation point under the shared responsibility model. Infrastructure as a Service (IaaS) limits provider management to physical facilities and hardware virtualization. Platform as a Service (PaaS) extends provider control to the operating system and runtime environment. Software as a Service (SaaS) places responsibility for the entire application stack on the cloud provider.

Adım Adım Çözüm

1
Identify provider management responsibilities for Infrastructure as a Service (IaaS).
IaaS providers handle physical hardware, data center security, networking hardware, and the virtualization hypervisor.
IaaS supplies basic computing resources, leaving higher OS and software management to the client.
2
Identify provider management responsibilities for Platform as a Service (PaaS).
PaaS providers manage the operating system, database engines, web servers, and runtime execution frameworks in addition to physical resources.
PaaS abstracts operating system and runtime maintenance away from developers.
3
Identify provider management responsibilities for Software as a Service (SaaS).
SaaS providers manage the entire application service end-to-end.
SaaS delivers ready-to-use software directly to end users without requiring client infrastructure administration.

Cevap

The enterprise server past EOL matches Unsupported software vulnerability; the network management service transmitting plain text credentials matches Cleartext transmission vulnerability; the network switch with factory credentials matches Default configuration vulnerability; and the corporate network without subnets or VLANs matches Architecture / Lack of network segmentation vulnerability.
Each scenario directly illustrates a core infrastructure vulnerability category: operating an unpatched EOL system creates an unsupported software vulnerability; transmitting unencrypted credentials creates a cleartext transmission vulnerability; retaining factory passwords creates a default configuration vulnerability; and placing all devices on a flat, unsegmented network creates an architecture vulnerability.

Adım Adım Çözüm

1
Analyze host-level system lifecycle status
Identify that running software beyond vendor support end date leaves unpatched flaws exposed
Systems past EOL represent unsupported software vulnerabilities.
2
Analyze network protocol transmission behavior
Identify that transmitting sensitive administrative data without cryptographic protection allows packet sniffing
Unencrypted traffic constitutes a cleartext transmission vulnerability.
3
Evaluate system configuration hardening
Identify that active factory credentials on network hardware enable easy unauthorized initial access
Using factory settings creates a default configuration vulnerability.
4
Evaluate network topology and boundaries
Identify that missing subnets or logical isolation allow unrestricted network traffic between low-trust guests and high-trust servers
A flat network lacking isolation represents an architecture vulnerability.
