Containing threat actors at the edge

As sophisticated threat actors increasingly target edge infrastructure like Citrix NetScaler, organizations must adopt an "assume breach" mentality focused on containment rather than relying solely on patching. Effective defense requires implementing strict micro-segmentation, isolating management interfaces, and minimizing the pre-authentication attack surface to limit an attacker's ability to move laterally. Additionally, externalizing security logs to a hardened SIEM is crucial for maintaining visibility even if attackers attempt to erase local evidence of an intrusion.
