As it turns out, even the most robust edge security measures can be bypassed by sophisticated attackers who expertly hide their malicious activity within seemingly legitimate user sessions. Despite having a multitude of security controls at our disposal, including request inspection, credential validation, device fingerprinting, and automation signals, cybercriminals continue to evade detection.
The reason for this lies in the fact that each security control focuses on a distinct aspect of a user session, leaving gaps that attackers can exploit. For instance, if an attacker uses a residential IP or a commercial VPN, they may pass through multiple layers without triggering an alert or action. This is largely due to a fundamental issue with existing edge security tooling: the lack of context surrounding the underlying infrastructure.
Application security relies on various layers of defense, each designed to answer a specific question about incoming traffic. Content Delivery Networks (CDNs) and Web Application Firewalls (WAFs), for example, are highly effective at inspecting requests, enforcing policies, filtering known threats, and protecting applications at the edge. However, these controls may not reveal that a seemingly ordinary connection is being routed through infrastructure intended to disguise its origin.
Bot management helps identify automation and distinguish bots from human users, but malicious sessions can be both automated and designed to resemble legitimate consumer traffic. Identity and authentication systems attempt to determine whether users can prove who they claim to be, yet valid credentials do not necessarily mean the person presenting them is the genuine account holder. Device and browser intelligence provides a layer of trust by describing the endpoint, but it doesn’t expose the network infrastructure connecting that endpoint to the application.
Individually, these signals provide valuable insights; however, attackers increasingly exploit the gaps between them, creating sessions that appear legitimate to any one control while concealing important context about the infrastructure behind the connection. This is where a new layer of context comes into play: intelligence about the infrastructure behind the live session.
Enter Monocle Session Enrichment, developed by Spur Intelligence, which adds real-time infrastructure context to existing controls. By combining visibility into Internet infrastructure with live session telemetry, Monocle creates a real-time Session Trust Assessment that goes beyond simply labeling an IP as good or bad. This assessment provides attributes that the enforcement layer can use when deciding how to handle the session.
For instance, a Session Trust Assessment might include signals describing what Monocle observes about the session, such as whether it’s anonymized, proxied, or uses AI-driven traffic. The decision is based on an organization’s configured policy, and governance data makes the assessment traceable. This additional layer of context enables security teams to make more informed decisions about edge enforcement.
In conclusion, while robust security measures are crucial for protecting applications at the edge, they can be bypassed by attackers who exploit the gaps between different security controls. To stay ahead of these threats, it’s essential to incorporate a new layer of context – intelligence about the infrastructure behind live sessions – into existing security stacks. By doing so, organizations can reduce authentication risks and minimize friction for legitimate users.
