Threat Modeling Cheat Sheet

Last revision (mm/dd/yy): 02/26/2016 Introduction DRAFT CHEAT SHEET - WORK IN PROGRESS Introduction Application Security Threat Modeling Steps Define The Target Of Evaluation Create a logical map of the Target of Evaluation Create a physical map of the Target of Evaluation Identify the Assets within the physical and logical Targets of Evaluation Define The Attackers Identify Possible Attackers that could exist within the Target Of Evaluation Use Means, Motive, and Opportunity to understand Threats posed by Attackers Rank Attackers from least dangerous to most dangerous based on Means, Motive & Opportunity Select the most dangerous Attacker in your Target Of Evaluation Conduct the Threat Model Assume the attacker has a zero day, because he does. In this methodology we assume compromise; because a zero day will exist or already does exist (even if we don't know about it). This is about what can be done by skilled attackers, with much more time, money, motive and opportunity than we have. Enumerate Threats posed by most dangerous Attacker in Target of Evaluation Enumerate Threats posed by most dangerous attacker in designated areas of the physical & logical Maps of the Target of Evaluation For logical map example: External firewall boundary, Internal firewall boundary, application server, and internal network. For physical map example: External to company (wifi attacks from parking lots for example), inside company branch (consultant on local network), in data centre (oops!). Enumerate Attacks posed by most dangerous attacker in designated areas of the logical and physical maps of the target of evaluation Not used in this methodology (compromise is assumed and not demonstrated - just because we can't get in doesn't make it risk free...) - Application Decomposition - Attack Tree - Vulnerability/Exploit Mapping - Application Testing create risks in risk log for every identified threat or attack to any assets rank risks using risk matrix from most severe to least severe Identify risk owners Remediation/Countermeasures Agree on risk mitigation with risk owners and stakeholders tolerate, transfer, treat, terminate Treat risks accordingly Test risk treatment to verify remediation Reduce risk in risk log for verified treated risk Periodically retest risk Authors and Primary Editors TODO Other Cheatsheets V - T - E Cheat Sheets Developer / Builder 3rd Party Javascript Management Access Control AJAX Security Cheat Sheet Authentication (ES) Bean Validation Cheat Sheet Choosing and Using Security Questions Clickjacking Defense Credential Stuffing Prevention Cheat Sheet Cross-Site Request Forgery (CSRF) Prevention Cryptographic Storage C-Based Toolchain Hardening CSS Security Deserialization DOM based XSS Prevention Forgot Password HTML5 Security HTTP Strict Transport Security Injection Prevention Cheat Sheet Injection Prevention Cheat Sheet in Java JSON Web Token (JWT) Cheat Sheet for Java Input Validation Insecure Direct Object Reference Prevention JAAS Key Management LDAP Injection Prevention Logging Mass Assignment Cheat Sheet .NET Security OS Command Injection Defense Cheat Sheet OWASP Top Ten Password Storage Pinning Query Parameterization REST Security Ruby on Rails Session Management SAML Security SQL Injection Prevention Transaction Authorization Transport Layer Protection TLS Cipher String Configuration Unvalidated Redirects and Forwards User Privacy Protection Web Service Security XSS (Cross Site Scripting) Prevention XML External Entity (XXE) Prevention Cheat Sheet Assessment / Breaker Attack Surface Analysis REST Assessment Web Application Security Testing XML Security Cheat Sheet XSS Filter Evasion Mobile Android Testing IOS Developer Mobile Jailbreaking OpSec / Defender Virtual Patching Vulnerability Disclosure Draft and Beta Application Security Architecture Business Logic Security Content Security Policy Denial of Service Cheat Sheet Grails Secure Code Review IOS Application Security Testing PHP Security Regular Expression Security Cheatsheet Secure Coding Secure SDLC Threat Modeling All Pages In This Category
