Implementation of a secure authentication and authorization

I provide services for the development and implementation of secure authentication and authorization solutions for web and mobile applications. This includes:

● Deployment of authentication systems based on OAuth 2.0 and JWT (JSON Web Token), ensuring secure user identity verification and access restrictions based on roles;

● Configuration of controlled access to APIs and internal resources, including creating roles, access policies, and permission checks before each user action;

● Implementation of best security practices, including restricting acceptable algorithms for signing tokens, mandatory validation of their validity before use, handling tokens exclusively through HTTP-only cookies to prevent theft via XSS;

● Use of tools for vulnerability detection and mitigation, such as solutions from Conviso AppSec, enabling comprehensive security audits, penetration testing, and threat elimination;

● Conducting security audits of applications to identify potential issues early in development, helping to avoid costs associated with fixing problems after deployment;

● Consulting on the implementation of multi-factor authentication (MFA), session management, and monitoring of suspicious user activities.

My goal is to create an attack-resistant system and ensure maximum protection for your users and data without compromising usability.
