Detecting Credential Stealing Attacks Through Active In-Network Defense


Today, enterprises tend to use multiple layers of security defenses, ranging from perimeter defense on network entry points to host based security solutions deployed at the end user’s machines to counter the ever-increasing threats. This includes inline traffic filtering and management security solutions deployed at access and distribution layers in the network, as well as out of band solutions like NAC, SIEM or User Behavior Analysis to provide identity-based network access and gain more visibility into the user’s access to critical network resources. However, layered security defenses face the major and recurring challenge of detecting newer exploitation techniques as they heavily rely on known behaviors. Additionally, yet another significant challenge facing the enterprise network is detecting post-exploitation activities, after perimeter security is compromised.
