Building Security In Maturity Model and Threat Analysis D487 Questions With complete verified solutions already graded A+(PASS GUARANTEED)

BSIMM

Building Security In Maturity Model; studies real-world software security initiatives for benchmarking.

SAMM

Software Assurance Maturity Model - prescriptive framework.

Key Distinction

BSIMM is descriptive (what organizations actually do) vs SAMM is prescriptive (what you should do).

Governance

Strategy, compliance, training programs.

Intelligence

Attack models, security features, standards research.

SSDL Touchpoints

Hands-on security activities such as code review and testing.

Deployment

Configuration management, vulnerability management.

STRIDE

Threat modeling framework.

Spoofing

Identity impersonation attacks.

Tampering

Unauthorized data modification.

Repudiation

Denial of performed actions.

Information Disclosure

Unauthorized data access.

Denial of Service

Service availability attacks.

Elevation of Privilege

Unauthorized access escalation.

DREAD

Risk scoring model. Damage, Reproducibility, Exploitability, Affected users, Discoverability

Ternary Scale

High=3, Medium=2, Low=1.

Damage

Potential impact severity.

Reproducibility

How easily an attack can be repeated.

Exploitability

Difficulty of executing the attack.

Affected users

Scope and number of impacted users.

Discoverability

How easy a vulnerability is to find.

Total Score Interpretation

13-15 points = High Risk, 8-12 points = Medium Risk, 5-7 points = Low Risk.

PASTA

Process for Attack Simulation and Threat Analysis.

Seven-Stage Methodology

Define Objectives, Define Technical Scope, Application Decomposition, Threat Analysis, Vulnerability and Weakness Analysis, Attack Modeling, Risk and Impact Analysis.

Microsoft Threat Modeling

Four-Step Process: Diagram, Identify, Mitigate, Validate.

OCTAVE

Operationally Critical Threat, Asset, and Vulnerability Evaluation.

Three Phases of OCTAVE

Phase 1: Build asset-based threat profiles, Phase 2: Identify infrastructure vulnerabilities, Phase 3: Develop security strategy and plans.

TRIKE

Risk-based approach to security.

SDL Phases

Includes A1: Security Assessment, A2: Architecture, A3: Design and Development, A4: Design and Development (readiness), A5: Ship.
