The article explores the dynamics between adaptive attacks and countermeasures in the context of a defense mechanism. It illustrates how defenses can diminish the success rate of adversarial attacks, particularly noting that under limited attack budgets, adaptive attackers struggle to achieve desired outcomes due to increased perceptible perturbations needed. However, a higher attack budget could enable more effective bypassing of defenses, suggesting that while defenses are beneficial, attackers might still exploit vulnerabilities given sufficient resources.
The findings reveal that implementing a defense mechanism, while it complicates the attack process for adversaries, doesn't render attackers completely ineffective, especially with larger budgets.
Our results clearly demonstrate that adaptive attacks require greater perturbations to overcome defenses, validating the efficacy of simple pre-processing methods in bolstering robustness.
