Unmasking external exposure in the Cloud with Real-Time Firewall Context

In the dynamic realm of cloud security, the challenge of maintaining a comprehensive view of your environment can feel like navigating a complex Kabuki play. The illusion of security, created by disconnected security tools, often leads to costly investigations and wasted resources. This is especially true when it comes to understanding the interplay between your cloud infrastructure and your perimeter firewalls.

The Context Conundrum

You can't protect what you don't fully understand. True security relies on having a complete understanding of your assets, their vulnerabilities, and their current state. This context is crucial to avoid the pitfalls of false positives and delayed responses.

Cloud environments are particularly challenging due to their layered complexity, encompassing network reachability, identity management, and security control configurations. Without a unified view, security teams are left grappling with fragmented data, leading to misinterpretations and inefficiencies.

Cloud Kabuki: A False Sense of Security

Enterprises frequently deploy robust firewalls such as Palo Alto NGFW, FortiGate and Cloud Provider WAFs and Firewalls to safeguard their cloud assets. However, a disconnect between these firewalls and native cloud security controls creates a dangerous blind spot. This gap leads to:

• Fragmented Visibility: Firewalls operate independently, obscuring the true exposure of cloud resources.

• False Positives and Negatives: Alerts are misinterpreted due to a lack of network context, leading to unnecessary investigations or missed threats.

• Cloud-Native Complexity: Traditional tools fail to account for the multi-layered nature of cloud exposure, including security groups, route tables, and internet gateways.

• Delayed Incident Response: Piecing together the puzzle of internet exposure during an incident wastes critical time.

• Patch Prioritization Gaps: Without understanding which assets are truly protected by firewalls, prioritizing patches becomes a guessing game.

Stream Security: Unmasking the Truth with Real-Time Cloud Visibility and Comprehensive Firewall Context

Stream Security dismantles the Cloud Kabuki with its innovative firewall unmasking capabilities. By correlating rules in Palo Alto firewalls with real-time cloud threat visibility, Stream provides a unified understanding of your security posture. This integration enhances SecOps efficiency by:

• Eliminating false positives by revealing which alerts are already mitigated by firewall rules.

• Improving threat prioritization by highlighting real threats that bypass firewall protections.

• Streamlining incident response by providing immediate clarity on asset exposure and firewall protection.

• Optimizing security posture by recommending targeted changes to firewall rules or cloud configurations.

Stream's Real-Time Context Layers

Stream Security goes beyond basic detection by providing real-time context across multiple layers:

• Real-Time Network Reachability: Understand how resources are interconnected and exposed to external access.

• Real-Time Identity: Gain insights into human and non-human identities and their privileges.

• Real-Time Exposure: Analyze the exploitable weaknesses of assets in real-time.

• Real-Time Security Controls: Understand how existing security controls mitigate potential threats.

Context-Driven Mitigation: A Real-World Example

Consider an RCE vulnerability on an internet-exposed EC2 instance. Without context, mitigation options are limited and potentially disruptive:

• Reverting configuration changes might not be feasible for business needs.

• Patching could lead to unacceptable downtime.

• Updating WAF configurations.

Stream Security’s real-time visibility allows teams to make informed decisions, considering the current threat landscape and operational requirements. By having the real time firewall context, a security team will be able to see that the RCE exploit is already blocked by a firewall rule, and can focus on patching during a maintenance window, instead of causing an emergency patch that disrupts production.

Reducing False Positives, Improving Efficiency

By providing real-time, layered context, Stream Security empowers security teams to focus on genuine threats, reducing false positives and improving overall efficiency. Stream's firewall unmasking capabilities are a game-changer, providing the clarity needed to navigate the complexities of cloud security and eliminate the illusions of the Cloud Kabuki.

Ensure your cloud environment remains secure and efficient by leveraging Stream Security’s real-time insights and mitigation strategies.
