BGP Hijacking
What is BGP Hijacking?
BGP Hijacking is a core network security concept in cybersecurity. It describes techniques, risks, or controls that defenders and ethical hackers must understand to protect systems and conduct authorized security testing. Learning BGP Hijacking helps you recognize attacks in the wild and apply industry-standard mitigations aligned with frameworks like OWASP and NIST.
BGP Hijacking sits within Network Security and is commonly encountered at the advanced level of security practice. Practitioners study how BGP Hijacking appears during reconnaissance, exploitation, or defense-in-depth design. On Codelivly, you explore BGP Hijacking through structured lessons and safe practice environments so you can map theory to hands-on outcomes without risking production systems. Understanding indicators, blast radius, and logging around BGP Hijacking improves both penetration test reports and blue-team detection engineering.
How it works
BGP Hijacking typically begins when an attacker identifies a weak input path, misconfiguration, or trust boundary. The technique abuses normal application or network behavior to achieve unintended access, data exposure, or code execution. Defenders detect it through correlated logs, anomaly detection, and hardened configurations.
Prevention
To reduce risk from BGP Hijacking, apply defense in depth: validate input, enforce least privilege, patch promptly, segment networks, and monitor for known indicators. Regular authorized testing and secure SDLC practices help catch issues before attackers exploit them in production.
