sureness - Jvm security framework that focus on protection of rest api | Product Hunt

Home Page: usthe.com/sureness | su.usthe.com

🎡 Introduction

Sureness is a simple and efficient open-source security framework that focus on the protection of REST API.
Provide authentication and authorization, based on RBAC.
No specific framework dependency (supports Javalin, Spring Boot, Quarkus, Ktor, Micronaut and more).
Supports dynamic modification of permissions.
Supports WebSockets and HTTP containers (Servlet and JAX-RS).
Supports JWT, Basic Auth, Digest Auth, and can custom auth methods.
High performance with Dictionary Matching Tree.
Good extension interface, demos and documentation.

Sureness has a sensible default configuration, is easy to customize, and is not couple to any one framework, which enables developers to quickly and safely protect their projects in multiple scenarios.

📈 Benchmark


Benchmark test shows Sureness to lose 0.026ms performance compared to frameless application, Shiro lose 0.088ms, Spring Security lose 0.116ms.
In contrast, Sureness basically does not consume performance, and the performance (TPS loss) is 3 times that of Shiro and 4 times that of Spring Security.
The performance gap will be further widened as the api matching chain increases.

✌ Framework Sample Support

🔨 Quick Start

🐕 Some Conventions

  • Based RBAC, User-Role-Resource.
  • We treat API requests as a resource, resource format like requestUri===httpMethod.
    That is the request uri + request method(post,get,put,delete...) is considered as a resource as a whole.
    eg: /api/v2/book===get
  • User belongs some Role -- Role owns Resource -- User can access the resource.

Resource path matching see: URI Match

🐖 Add Sureness In Your Project

When use maven or gradle build project, add coordinate

compile group: 'com.usthe.sureness', name: 'sureness-core', version: '1.0.8'

🐵 Use the Default Configuration to Configure Sureness

The default configuration -DefaultSurenessConfig uses the document datasource sureness.yml as the auth datasource.
It supports JWT auth, Basic auth, Digest authentication.

public DefaultSurenessConfig surenessConfig() {
    return new DefaultSurenessConfig();

🐮 Load Auth Config DataSource

Sureness authentication requires us to provide our own account data, role permission data, etc. These data may come from text, relational databases, non-relational databases, annotations, etc.
We provide interfaces SurenessAccountProvider, PathTreeProvider for user implement to load data from the dataSource where they want.

  • SurenessAccountProvider - Account datasource provider interface.
  • PathTreeProvider - Resource uri-role datasource provider interface.

Default Document DataSource Config - sureness.yml, see: Default Document DataSource
Annotation DataSource Config Detail - AnnotationLoader, see: Annotation DataSource

If the configuration resource data comes from text, please refer to Sureness integration Spring Boot sample(configuration file scheme)
If the configuration resource data comes from dataBase, please refer to Sureness integration Spring Boot sample(database scheme)

🐐 Add an Interceptor Intercepting All Requests

The essence of Sureness is to intercept all rest requests for authenticating and authorizing.
The interceptor can be a filter or a Spring interceptor, it intercepts all request to check them.

SubjectSum subject = SurenessSecurityManager.getInstance().checkIn(servletRequest)

🐰 Implement Auth Exception Handling Process

Sureness uses exception handling process:

  • If auth success, method - checkIn will return a SubjectSum object containing user information.
  • If auth failure, method - checkIn will throw different types of auth exceptions.

Users need to continue the subsequent process based on these exceptions.(eg: return the request response)

Here we need to customize the exceptions thrown by checkIn, passed directly when auth success, catch exception when auth failure and do something:

try {
    SubjectSum subject = SurenessSecurityManager.getInstance().checkIn(servletRequest);
} catch (ProcessorNotFoundException | UnknownAccountException | UnsupportedSubjectException e4) {
    // Create subject error related execption 
} catch (DisabledAccountException | ExcessiveAttemptsException e2 ) {
    // Account disable related exception
} catch (IncorrectCredentialsException | ExpiredCredentialsException e3) {
    // Authentication failure related exception
} catch (UnauthorizedException e5) {
    // Authorization failure related exception
} catch (SurenessAuthenticationException | SurenessAuthorizationException e) {
    // other sureness exception

Detail see: Default Sureness Auth Exception

Have Fun

🥐 Advanced Use

Sureness supports custom subject, custom subjectCreator, custom processor and more.

Before advanced custom extension, let's first understand the general process of Sureness:


As in the above process, Subject is created by SubjectCreate according to the request body, and different authentication processors process the supported Subjects.

Sureness provides the following common interfaces as extension points:

  • Subject: Authenticated authorized user's account interface, provide the account's username,password, request resources, roles, etc.
  • SubjectCreate: Create subject interface, provider create method.
  • Processor: Process subject interface, where happen authentication and authorization.
  • PathTreeProvider: Resource data provider, it can load data from txt or database,etc.
  • SurenessAccountProvider: Account data provider, it can load data from txt or database,etc.

Refer to Extension Point for the extended documentation.

  1. 🥊 Custom Subject

Implment Subject, add custom subject content
Implment SubjectCreate to create custom subject
Implment Processor to support custom subject

See Custom Subject

  1. 🔫 Custom SubjectCreator

Implment SubjectCreate to create your custom subject

See Custom SubjectCreator

  1. 🪓 Custom Processor

A subject also can support by different processor, so we can custom processor to support custom subject Implment Processor, set which subject can support and implment processing details

See Custom Processor

  1. 🏹 Custom Datasource

Implment PathTreeProvider, load in DefaultPathRoleMatcher
Implment SurenessAccountProvide, load in processor

See Custom Datasource

Detail please refer to Sureness integration Spring Boot sample(database scheme)
