What is Threat Modeling?

A structured approach to identifying security threats in your system before attackers do. Think like a burglar to secure your house.

The STRIDE Framework

Six categories of security threats. For every component in your system, ask yourself these questions.

S

Spoofing

Identity theft and impersonation attacks

Can someone pretend to be another user or system?

Common Examples

Session hijackingPhishingCredential theft
T

Tampering

Unauthorized data modification

Can data be modified without detection?

Common Examples

SQL injectionMan-in-the-middleLog manipulation
R

Repudiation

Denying performed actions

Can users deny their actions without proof?

Common Examples

Missing audit logsUnsigned transactionsNo timestamps
I

Information Disclosure

Data leaks and exposure

Can sensitive data be accessed by unauthorized parties?

Common Examples

Data breachesError messagesInsecure storage
D

Denial of Service

System availability attacks

Can the system be made unavailable to legitimate users?

Common Examples

DDoS attacksResource exhaustionCrash exploits
E

Elevation of Privilege

Unauthorized access escalation

Can users gain higher privileges than allowed?

Common Examples

Privilege escalationBroken access controlToken manipulation

Four simple steps.

A systematic approach to finding and fixing security weaknesses before they become problems.

01

Map

Define your system architecture, zones, and data flows

Draw architecture diagram
Identify trust boundaries

02

Identify

Apply STRIDE to find potential threats

Review each component
Apply STRIDE categories
List potential threats
Output: Threat list
03

Assess

Rate severity and likelihood of each threat

Evaluate impact
Estimate likelihood
Calculate risk score
Output: Risk matrix
04
