Core Concepts
DevSecOps
Development, Security, Operations - the practice of integrating security testing and controls into every phase of the software development lifecycle.
Shift Left Security
Moving security testing and validation earlier in the development process, ideally during coding rather than after deployment.
Security as Code
Defining security policies, configurations, and infrastructure security controls through code that can be version controlled and automated.
Threat Modeling
Systematic approach to identifying potential security threats and vulnerabilities in applications and infrastructure during design phase.
Zero Trust Architecture
Security model that assumes no implicit trust and continuously validates every transaction before granting access to systems.
Security Gates
Automated checkpoints in CI/CD pipelines that prevent insecure code from progressing to the next stage of deployment.
Terms
Testing Tools
SAST (Static Application Security Testing)
Analysis of source code for security vulnerabilities without executing the program. Performed during the coding phase.
DAST (Dynamic Application Security Testing)
Security testing performed on running applications to identify vulnerabilities that manifest during execution.
IAST (Interactive Application Security Testing)
Hybrid approach combining SAST and DAST, analyzing applications during runtime with access to source code.
SCA (Software Composition Analysis)
Analysis of open source and third-party components in applications to identify known vulnerabilities and license risks.
Container Security Scanning
Analysis of container images for vulnerabilities, misconfigurations, and compliance issues before deployment.
Secrets Scanning
Automated detection of sensitive information like passwords, API keys, and certificates in code repositories.
Infrastructure as Code (IaC) Security
Security analysis of infrastructure configuration files (Terraform, CloudFormation) for misconfigurations and vulnerabilities.
Terms
Vulnerabilities
CVE (Common Vulnerabilities and Exposures)
Standardized identifier for publicly known cybersecurity vulnerabilities, maintained by MITRE Corporation.
CVSS (Common Vulnerability Scoring System)
Industry standard for assessing the severity of computer system security vulnerabilities (scale 0-10).
OWASP Top 10
List of the most critical web application security risks, updated regularly by the Open Web Application Security Project.
Supply Chain Attack
Cyber attack that targets third-party vendors or dependencies to compromise the primary target's systems.
Terms
Compliance
SOC 2
Security compliance framework focusing on five trust principles: Security, Availability, Processing Integrity, Confidentiality, Privacy.
GDPR (General Data Protection Regulation)
European Union regulation governing data protection and privacy for individuals within the EU and EEA.
HIPAA (Health Insurance Portability and Accountability Act)
US regulation establishing standards for protecting sensitive patient health information.
PCI DSS (Payment Card Industry Data Security Standard)
Information security standard for organisations that handle credit card information.
ISO 27001
International standard for information security management systems (ISMS) providing framework for managing sensitive information.
NIST Cybersecurity Framework
Framework providing guidelines for organisations to manage and reduce cybersecurity risk through five functions: Identify, Protect, Detect, Respond, Recover.
Terms
Security Tools
SIEM (Security Information and Event Management)
Technology solution that aggregates and analyzes security data from across the enterprise to detect threats.
SOAR (Security Orchestration, Automation and Response)
Collection of software solutions that enable security teams to automate responses to security incidents.
WAF (Web Application Firewall)
Security solution that monitors, filters, and blocks HTTP traffic to and from web applications.
EDR (Endpoint Detection and Response)
Cybersecurity solution that monitors endpoints for threats and provides investigation and response capabilities.
Penetration Testing
Authorized simulated cyber attack performed to evaluate the security of a system, network, or application.
Red Team/Blue Team
Red Team simulates attacks while Blue Team defends. Exercise helps improve security posture and incident response.
