JSON Web Tokens are the modern standard for stateless authentication, yet flawed implementations open the door to attackers. This article walks through the most common pitfalls such as algorithm confusion, unprotected payload data, and insecure storage, and delivers concrete, tested PHP solutions for robust API authentication.

API keys unlock interfaces for partners, marketplaces, and internal services, yet poorly managed keys remain one of the most common entry points for data breaches. This article shows how to generate API keys with sufficient entropy, scope them to minimal permissions, rotate them without downtime, and revoke them immediately on suspected compromise, with practical guidance for Magento backends.

Running forms and state-changing endpoints without real CSRF protection means relying solely on the browser's session cookie, opening the door to forged requests from other sites. Synchronizer tokens, double-submit cookies, the SameSite attribute, and Magento's form_key show how to close that gap reliably.

Storing or processing card data directly inside your own store multiplies the effort for audits, network segmentation and annual certification. Hosted fields, iframe tokenization and redirect payments keep Magento stores consistently outside PCI scope, reduce self-assessment overhead to SAQ A, and protect customers from data theft and skimming attacks at the same time.

Containers share the host kernel, so they are not an automatic security win over classic servers. This article shows how minimal base images, non-root users, automated vulnerability scanning in the CI pipeline, secure secrets handling without image layer leaks, and a hardened runtime with a read-only filesystem and reduced Linux capabilities make Docker deployments for Magento and PHP projects noticeably safer.

Broken Access Control has ranked number 1 in the OWASP Top 10 since 2021 and affects most tested web applications. This article explains IDOR, missing function-level access control, and privilege escalation via parameter tampering with concrete examples, then shows how to implement clean access control in Magento using ACL patterns and the principle of least privilege.

Hashing passwords with MD5 or SHA-1 leaves the door wide open for brute-force and rainbow-table attacks the moment a database leaks. This article explains how bcrypt and Argon2id actually work, how to use PHP's password_hash() correctly in production code, and which mistakes around salts, cost factors, and rehashing happen most often in real-world applications.

A valid TLS certificate alone does not protect a Magento store from clickjacking, MIME sniffing, or silent data leaks through the referrer header. This article shows in practice how HSTS, X-Content-Type-Options, Referrer-Policy, Permissions-Policy, and CSP frame-ancestors work together, how to configure these headers correctly at the webserver or CDN layer instead of in application code, and how scanners like securityheaders.com grade the result.

OAuth 2.0 handles authorization, OpenID Connect adds the missing identity layer, and confusing the two leads to insecure logins. This article explains the authorization code flow with PKCE as the current standard, covers common implementation mistakes around redirect URIs, state, and nonce, and shows how to integrate a social login securely into a Magento store.

Running unserialize on untrusted input such as cookies, session data, or API payloads opens the door to PHP Object Injection and dangerous gadget chains that abuse magic methods like wakeup and destruct to execute arbitrary code. This article explains the mechanics, shows safer alternatives like json_decode, and covers proven deserialization patterns for production PHP and Magento applications.
