Security testing guides — vulnerability scanning, penetration testing basics, and secure SDLC practices.
Security Testing
Web applications are the front door to your business. They handle user data, process payments, manage authentication, and connect to your most sensitive infrastructure. That makes them a prime target for attackers — and the reason penetration testing has become a non-negotiable part of any serious security program. This guide
API Testing
Authentication is where most API bugs hide. A missing header, an expired token, an incorrect scope — any of these can silently break a protected endpoint in ways that unit tests never catch. REST Assured makes authentication testing straightforward, giving you the tools to verify not just that authenticated requests work,
Security Testing
Dynamic Application Security Testing (DAST) attacks your running API to find vulnerabilities that static analysis misses: authentication bypass, BOLA/IDOR (Broken Object-Level Authorization), injection through actual HTTP requests, and security misconfigurations. This guide covers OWASP ZAP API Scan and Nuclei for REST API DAST in CI/CD pipelines. Why
Security Testing
Dynamic Application Security Testing (DAST) does what static analysis can't: it attacks your running application the same way a real attacker would. Where SAST reads code, DAST sends HTTP requests, follows redirects, submits forms, and probes for weaknesses at the network layer. No source code required — which means
Security Testing
CVSS (Common Vulnerability Scoring System) is the standard scoring system used to rate the severity of software vulnerabilities. Scores range from 0 to 10: Critical (9.0–10.0), High (7.0–8.9), Medium (4.0–6.9), Low (0.1–3.9). CVSS Base scores measure inherent severity;
Fuzz Testing
Fuzzing's reputation is built on results. The technique has found some of the most significant software vulnerabilities of the past 30 years — not because it's clever, but because it's systematic and relentless. These case studies examine real-world bugs found by fuzzing, what each
Smart Contract Testing
Cross-chain bridges have been the most catastrophically exploited category of smart contracts. Ronin Bridge ($625M), Wormhole ($320M), Nomad ($190M), Harmony Horizon ($100M) — a combined $2+ billion drained in 18 months. The bugs differ, but the pattern is consistent: insufficient validation of messages crossing chain boundaries. This guide covers how
Security Testing
Static application security testing (SAST) finds vulnerabilities before your code ships. Coverity, from Synopsys, is one of the most widely deployed SAST tools in enterprise environments — used by teams that need low false-positive rates and deep language support. This guide covers what Coverity does, how to set it up,
Fuzz Testing
Coverage-guided fuzzing finds more bugs than random fuzzing because it learns from execution. Each input that exercises new code paths is kept; inputs that don't are discarded. Over time, the fuzzer builds a corpus that covers increasingly deep program states. Understanding how this works internally — instrumentation, coverage
Security Testing
Checkmarx is one of the most widely deployed SAST platforms globally, known for its extensive language support, customizable queries, and strong developer workflow integrations. If your organization has a formal AppSec program, Checkmarx SAST (now part of Checkmarx One) is likely on the shortlist. This guide covers how Checkmarx works,
AWS CDK
Writing CDK constructs that deploy working infrastructure is the easy part. Writing CDK constructs that deploy secure infrastructure — that's where teams struggle. CDK Nag is a static analysis tool that checks your CDK stacks against security and compliance rules before a single resource is deployed. This post covers
Security Testing
Burp Suite and OWASP ZAP are the two most widely used web application security testing platforms. Both function as intercepting proxies with active scanning capabilities. The choice comes down to cost, team size, automation requirements, and how much you rely on manual vs. automated testing. Overview Burp Suite (PortSwigger) is
