Master Secure Software Development : Complete CSSLP Guide

Master the CIA triad—confidentiality, integrity, availability—along with authentication, authorization, accountability, and non-repudiation, and learn the secure development lifecycle to embed security from the ground up.

Explore the CIA triad—confidentiality, integrity, and availability—and how access controls, encryption, hash checks, digital signatures, backups, load balancing, and disaster recovery preserve secure, reliable software.

Learn how authentication verifies identity, exploring factors like something you know, have, or are, and how MFA and IDM manage access using IDPs, certificates, and tokens.

Assign access levels and permissions to a subject requesting access to an object, based on activities like reading, writing, executing, or deleting, to protect CIA and enforce policies.

Accountability uses logging to record who did what and when, enabling problem detection and prevention. Management enforces auditing through defined roles, separating duties and addressing inherent, detection, and control risks.

Establish non-repudiation by combining authentication, authorization, and auditing to prove user actions in a system. Provide logs of actions and times to resolve disputes while balancing data volume and practicality.

Embed security into the secure development lifecycle with checks like code reviews, threat modeling, and security testing to produce high-quality, secure software.

Learn how the secure development lifecycle integrates security at every software development stage through team training, security gates, threat modeling, fuzzing, reviews, and risk mitigation.

Master confidentiality, integrity, and availability along with authentication, authorization, accountability, and non-repudiation, and examine secure development lifecycle elements like team awareness, security requirements, threat modeling, and reviews.

Define software requirements early to guide design, construction, and testing, emphasizing functional security requirements and non-functional operational and deployment needs; clear requirements reduce costs and delays.

Cover system tenets like session management, exception handling, and configuration management, showing how to secure communications, manage failures, and maintain stable production environments.

Apply secure design tenets to architecture and planning of systems. Emphasize least privilege, defense in depth, complete mediation, open design, and fail safe concepts.

Explore adversaries in security, from natural disasters to human attackers, including script kiddies, hackers, crackers, and nation-state threats, and how structured threats demand adaptive defenses.

Explore secure design principles and security models, including system tenets, threats and adversaries, and access control models, with Bell-lapadula, Biba, Clark-wilson, and Brewer Nash.

Explore how security models integrate people, processes, and technology to strengthen access control and data flow. Compare mandatory, discretionary, role-based, and attribute-based access control, plus assurance and operational frameworks.

Define software requirements to guide design, construction, and testing; treat them as the blueprint for secure software, covering functional requirements and non-functional needs like operational and deployment in the SDLC.

Define functional requirements from business needs and security requirements, capture role and user definitions, and outline subject–object concepts, access controls, use cases, and timing for secure development.

Define functional requirements from business, architecture, and security teams to clarify roles, map the subject object activity matrix, and ensure secure operations in the sdlc.

Explore compliance requirements and regulations shaping secure software development, and learn data classification and privacy practices to protect user information. Embed security across the development lifecycle to build robust software.

Explore regulations and compliance in the enterprise, contrast security with compliance, and embed security throughout the software development life cycle to meet HIPAA, GDPR, PCI DSS, and ISO standards.

Explore data classification to align protection with data value and high, medium, and low risk across states, usage, and life cycle, applying ownership, custodianship, labeling, and impact analysis.

Explore how privacy in modern software development extends beyond laws to give individuals control over data collection, use, and protection, including PII, PHI, encryption, and breach notifications.

Develop and analyze misuse and abuse cases to strengthen software security, and use the security requirements traceability matrix RTM to ensure security needs are communicated to suppliers and providers.

Define misuse and abuse cases to deny unauthorized actions and guide use cases and threat modeling in requirements, with collaborative security testing.

Explore how the requirements traceability matrix (rtm) links security requirements to implementation and testing. Track fields like requirement id, description, source, test objective, verification method, and use cases.

Explore software acquisition in secure development, covering build versus buy, outsourcing risks, and how to select and integrate COTS and GOTS components with clear SLAs and SBOMs.

Explore misuse and abuse cases to define prohibited actions, and introduce the requirements traceability matrix (rtm) for managing security requirements through the software supply chain as enforceable contracts.

Threat modeling identifies potential threats and defines a secure software architecture to build security into the software from day one, with defenses that withstand attacks.

Learn to perform threat modeling by defining security objectives, decomposing the system with data flow diagrams, and using the Stride model to identify threats and plan mitigations.

Define secure architecture through security controls in administrative, technical, and physical categories and their preventive, detective, and compensating roles; review distributed architectures like client-server, peer-to-peer, and SOA with ESB.

Review the secure software architecture concepts by examining threat modeling, how to create a threat model for a system, and the security implications of different architectures.
