Progress0%

0 of 40 completedScore: 0/100

1. Broken Access Control

Failures related to access control that allow unauthorized access to data or functionality

Do you enforce access controls on every request?

Access control checks should be performed server-side for every request

critical

Do you prevent users from modifying access control checks?

Access control decisions should not be client-side or easily bypassed

critical

Do you implement proper authorization checks for API endpoints?

Every API endpoint should verify user permissions before processing requests

high

Do you use indirect object references or verify ownership?

Prevent direct object references or validate user ownership of resources

high

2. Cryptographic Failures

Failures related to cryptography that lead to exposure of sensitive data

Do you encrypt all sensitive data in transit using TLS?

Use HTTPS/TLS for all connections transmitting sensitive data

critical

Do you encrypt sensitive data at rest?

Sensitive data should be encrypted when stored

critical

Do you use strong, modern cryptographic algorithms?

Avoid deprecated algorithms like MD5, SHA1, DES, RC4

high

Do you properly manage and rotate cryptographic keys?

Implement secure key storage and rotation policies

high

3. Injection

User-supplied data is not validated, filtered, or sanitized

Do you use parameterized queries or prepared statements?

Never concatenate user input into SQL queries

critical

Do you validate and sanitize all user inputs?

Implement input validation on server-side for all user data

critical

Do you use safe APIs that avoid interpreter usage?

Use ORM frameworks and safe APIs instead of raw queries

high

Do you implement allowlists for input validation?

Define what is allowed rather than blocking known bad patterns

medium

4. Insecure Design

Missing or ineffective control design

Do you perform threat modeling during design phase?

Identify and address security threats early in development

high

Do you implement rate limiting and resource quotas?

Protect against abuse and DoS attacks

high

Do you follow secure design principles (defense in depth, least privilege)?

Apply security-by-design principles throughout the application

high

Do you segregate tenants and users properly?

Ensure proper isolation between different users and organizations

critical

5. Security Misconfiguration

Missing security hardening or improperly configured permissions

Do you use secure default configurations?

Remove default accounts, disable unnecessary features

critical

Do you implement security headers?

Use HSTS, CSP, X-Frame-Options, etc.

high

Do you keep all software up to date?

Regularly update frameworks, libraries, and dependencies

critical

Do you disable directory listing and verbose errors in production?

Prevent information disclosure through error messages

medium

6. Vulnerable and Outdated Components

Using components with known vulnerabilities

Do you inventory all components and their versions?

Maintain a software bill of materials (SBOM)

high

Do you regularly scan for vulnerable dependencies?

Use tools like npm audit, Snyk, or Dependabot

critical

Do you only use components from trusted sources?

Verify integrity and authenticity of third-party components

high

Do you have a process for applying security patches?

Regularly update dependencies and apply security patches

critical

7. Identification and Authentication Failures

Weaknesses in authentication and session management

Do you implement multi-factor authentication (MFA)?

Require MFA for sensitive operations and accounts

critical

Do you enforce strong password requirements?

Require minimum length, complexity, and check against breach databases

high

Do you implement account lockout and rate limiting?

Protect against brute force and credential stuffing

high

Do you use secure session management?

Generate new session IDs on login, implement proper timeouts

critical

8. Software and Data Integrity Failures

Failures related to code and infrastructure that don't protect against integrity violations

Do you verify integrity of updates and dependencies?

Use digital signatures and checksums for software updates

high

Do you secure your CI/CD pipeline?

Implement access controls and integrity checks in build process

high

Do you avoid insecure deserialization?

Validate and sanitize serialized objects, prefer JSON over native serialization

critical

Do you implement subresource integrity (SRI) for external resources?

Use SRI tags for CDN-hosted scripts and styles

medium

9. Security Logging and Monitoring Failures

Insufficient logging, monitoring, and incident response

Do you log all security-relevant events?

Log authentication, authorization failures, and sensitive operations

high

Do you protect logs from tampering?

Store logs securely and prevent unauthorized modification

high

Do you monitor and alert on suspicious activities?

Implement real-time monitoring and alerting for security events

high

Do you have an incident response plan?

Establish procedures for detecting and responding to breaches

critical

10. Server-Side Request Forgery (SSRF)

Fetching remote resources without validating user-supplied URLs

Do you validate and sanitize all URLs from user input?

critical

Do you disable or restrict URL redirects?

Avoid automatic redirects based on user input

high
