How does the 'apex' of a DDoS attack relate to the overall attack vector?

The 'apex' is a key component of the overall DDoS attack vector. The attack vector describes the path the malicious traffic takes to reach the target. The 'apex' is usually the point of highest concentration and amplification within that vector, making it the most vulnerable and the most easily targeted. By focusing on the apex, defenders can significantly reduce the overall impact of the attack, even if the attack vector itself is complex.
