A “Perfect” 10 vulnerability score is not what users of Cisco Ultra-Reliable Wireless Backhaul (URWB) systems were expecting. The recently discovered cybersecurity vulnerability CVE-2024–20418 is remote, easy, and gives full Admin rights to the device. That is potentially a devastating combination (hence the CVSS score of 10)!

Probably some overtime hours are in store for those patching these systems:

- Catalyst IW9165D Heavy Duty Access Points
- Catalyst IW9165E Rugged Access Points and Wireless Clients
- Catalyst IW9167E Heavy Duty Access Points.

The more strategic concern is that these devices are the type of systems that would be purchased and installed to protect either very sensitive systems or environments that cannot be easily patched — like Operational Technology (OT). 

Given that a large portion of our Critical Infrastructure uses OT environments, this vulnerability represents a risk to crucial services we all rely upon, including telecommunications, power, water, transportation, and healthcare systems.

Have a good weekend!

"Perfect Vulnerability for CISO Ultra Reliable Systems" seems like it could refer to a conceptual exploration of the roles and challenges faced by Chief Information Security Officers (CISOs) in maintaining ultra-reliable systems in an era of increasing cyber threats. Below is a summary that could serve as an overview or background for a story or an article on this topic.

Summary: Perfect Vulnerability for CISO Ultra Reliable Systems

Introduction

In an age where digital transformation and reliance on technology have reached new heights, organizations strive to achieve ultra-reliable systems. These systems are critical not just for operational success but also for maintaining consumer trust and protecting sensitive data. However, the more complex these systems become, the more vulnerabilities emerge.

The Role of the CISO

Chief Information Security Officers (CISOs) are at the forefront of this battle, tasked with creating a robust security framework that identifies vulnerabilities, mitigates risks, and ensures the reliability of systems. Their role goes beyond implementing technology; it encompasses strategic thinking, communication, and leadership.

The Paradox of Vulnerability

As organizations aim for ultra-reliability, a paradox arises: the notion of "perfect vulnerability." This is the idea that, despite best efforts, no system can be entirely impervious to attack. A CISO must acknowledge this vulnerability and adopt a mindset that seeks not to eliminate it but to manage it effectively.

  1. Understanding Threat Landscapes:

    • The threat landscape is constantly evolving, with cybercriminals employing more sophisticated techniques. CISOs must maintain awareness and adapt their strategies.
  2. Building a Culture of Security:

    • It's not enough to rely solely on technology; CISOs must foster a culture where every employee understands the importance of security, encouraging them to report suspicious activities and recognize potential vulnerabilities.
  3. Balancing Security and Usability:

    • As systems become more secure, they can become cumbersome for users. CISOs need to find a balance between implementing robust security measures and maintaining usability to ensure that systems remain effective and do not hinder business operations.
  4. Incident Response and Learning:

    • Accepting that vulnerabilities exist means preparing for the inevitable incidents. CISOs must establish solid incident response plans and learn from breaches to improve the system continuously.
  5. Embracing Collaboration:

    • Collaboration with other departments—from IT to human resources—is essential. Security cannot function in a silo; fostering interdepartmental communication is crucial for identifying vulnerabilities and protecting sensitive information.

Conclusion

"Perfect Vulnerability" is not about succumbing to defeat; it is about understanding that vulnerability is a part of the digital landscape. A CISO's ability to navigate this reality, build resilience in their organizations, and prepare for the unpredictability of cyber threats is what leads to the development of ultra-reliable systems. In this complex environment, the pursuit of security becomes an ongoing journey rather than a fixed destination.

Through this lens, CISOs can leverage their insights and strategies to create a more resilient organization, transforming the nature of vulnerabilities from points of weakness to opportunities for growth.
