To address the limitation of a system that only provides notifications when a potential breach occurs, implementing a solution that can take preventative action is necessary. An Intrusion Prevention System is designed to not only detect but to preventively respond to threats by blocking them, therefore enhancing the network's defensive capabilities. The options of bolstering data loss prevention (DLP) strategies, incorporating additional security information and event management (SIEM) features, and enhancing public key infrastructure (PKI) are all valuable in their respective contexts. However, none of these solutions are purposed to block malicious traffic in the way an Intrusion Prevention System would. DLP focuses on preventing data leaks, SIEM centralizes logging and provides threat detection, and PKI deals with encryption and authentication, not inline traffic analysis and intervention.
