How did Wireshark come to be, and what’s made it so successful – not just as the pre-eminent tool for analyzing network packet data, but as an open-source project in general?

In this episode I talk to Wireshark founder, Gerald Combs, and Endace CTO, Stephen Donnelly, about the origins of Wireshark, and why packet capture data is so crucial for investigating and resolving network security threats and network or application performance issues.

Gerald talks about the early days of Ethereal, a “packet sniffer” he originally created for his own use in his role at an ISP, but subsequently open-sourced as Wireshark. That fortuitous decision was key, Gerald says, to the subsequent ongoing growth and success of the Wireshark project – which will turn 25 years old in July! It enabled developers from around the world to contribute to the project, creating a Windows version in the process, and helping Wireshark to become the gold standard tool for network analysis, used by SecOps, NetOps and IT teams the world over.

Stephen has been using Wireshark right from the earliest days – when it was still called Ethereal – and is one of the many contributors to the project.Stephen and Gerald both talk about why packet analysis is so important for cybersecurity and network performance analysis (the ubiquitous “Packets Don’t Lie” T-shirt – available from the Wireshark Foundation store – says it all really), and discuss examples of the many and varied problems that Wireshark is helping people to solve.

Stephen outlines the differences between network flow data and packet capture data and why packet data is essential for solving some problems where flow data just doesn’t contain the level of detail required.

Wireshark is continually evolving, with support for new protocols, and new UI enhancements that make it easier for analysts to slice-and-dice packet data. Gerald says that Wireshark is almost the perfect open-source project because it allows for a lot of parallel collaboration from contributors in creating new dissectors and ensuring that Wireshark continues to keep pace with the rapid pace of change in networking. Now that planning for Wireshark 5.x has started Gerald also looks ahead to some of the possible new features that might appear in future releases.

And finally, Gerald talks about the new Wireshark Foundation (which Endace is a sponsor of) which has been setup to provide support for ongoing development of the Wireshark project and ensure it continues its resounding success into the future.

Wireshark is coming up on its 25th birthday and still going from strength-to-strength. Don’t miss this fascinating interview with the leader of one of the most successful open-source projects around. Gerald and Stephen’s insightful commentary as well some fantastic tips-and-tricks make this a must-watch episode.

Increasingly complex systems, expanding threat landscape, and explosion in the number of potential entry points all make managing security at scale a daunting prospect. So what can you do to implement effective security at scale and what are some of the pitfalls to avoid?

In this episode I talk with Dimitri McKay, Principal Security Strategist and CISO Advisor at Splunk, about where to start addressing the challenges of security at scale. He highlights the importance of robust risk assessment, developing clear security goals and ensuring leadership buy-in to the organization’s security strategy. And the importance of balancing the needs of users with the need to secure the enterprise.

Dimitri discusses some of the pitfalls that organizations often fall into, and what security leaders can do – and where they should start – to avoid making the same mistakes. He talks about the importance of thinking strategically not just tactically, of being proactive rather than just reactive, and of creating a roadmap for where the organization’s security needs to be in a year, two years, three years into the future.

Dimitri also highlights the need to collect the right data to ensure the organization can accomplish the security goals it has set, to enable high-fidelity threat detection and provide the necessary context for effective, and efficient, threat response. Security teams started by collecting what they had he says – firewall logs, authentication logs etc. – but this isn’t necessarily sufficient to enable them to accomplish their objectives because it focuses more on IT risks, rather than on the critical business risks.

Finally, Dimitri puts on his futurist hat to predict what security teams should be on the look out for. Not surprisingly, he predicts the rapid development of AI tools like ChatGPT and OpenAI has huge potential benefits for cyber defenders. But these tools will also enable cyber attackers to create increasingly sophisticated threats and circumvent defences. AI is both an opportunity and a threat.

Cyberthreats are something all organizations are facing. But Pharmaceutical and Healthcare Providers have some unique challenges and vulnerabilities and come in for more than their fair share of attention from threat actors. What can your SOC team learn from some of the best practices these organizations are implementing? Are you architecting your environment to separate IOT devices from other critical assets and are you managing them with the same level of scrutiny?

In this episode I talk with David Monahan, a 30-year expert in cybersecurity and network management and former researcher at Enterprise Management Associates. David draws on his research background as well as his current experience working as the Business Information Security Officer at a large global pharmaceutical company.

He talks about some of the similarities and differences the Healthcare and Pharmaceutical industries have with other industries. He shares his insights into why the Healthcare and Pharmaceutical industries are so strongly targeted by threat actors and things consumers or patients can do to help protect themselves and their information.

David also discusses some of the unique challenges Healthcare organizations have around IOT devices and suggests ways to help manage these risks.  He shares some best practices your security organization can be leveraging and points out tools and solutions that are critical for any security stack.

Finally, David talks about what training and skills are important to ensure your SOC analysts are as prepared as possible to defend against cyberthreats.

As workloads move to the cloud, and infrastructure becomes increasingly complex, how can you ensure that your security posture evolves accordingly? It’s essential to ensure visibility across the entire network if you are to secure it effectively.

In this episode of the Endace Packet Forensic files, I talk with Jim Mandelbaum, Field CTO at Gigamon, about what “security at scale” means. Jim draws on more than a decade of experience as a CTO in the security industry, and shares best-practise tips to ensure that as your infrastructure evolves, your security posture keeps pace.

Jim highlights the importance of leveraging automation to help deal with the increasingly complex network environment. Key to this is having visibility into exactly what’s happening on your network – including on-prem, cloud and hybrid-cloud environments – so you can make informed decisions about what traffic needs to be monitored and recorded. And what tasks can be automated to ensure threat visibility.

It’s also critical to break down team silos, Jim says. Otherwise, responsibility has a tendency to fall through the cracks. Teams need to collaborate closely, and include the security team on IT strategy planning and particularly cloud migration projects. That makes it easier to determine who is responsible for what parts of security from the get-go. When teams have the opportunity to discuss the challenges they face they can often leverage solutions that have been successfully implemented elsewhere in the organization – saving time, resources and budget as a result.

Lastly, Jim highlights the importance of talking with your vendors about their future product strategies to ensure they align with your organization’s plans. Otherwise, there’s a risk of divergence which could prove very costly down the track.

We have all heard horror stories about how SOC teams are overwhelmed and facing a never-ending battle against threat actors. And we all recognize it is not a matter of IF but WHEN you get breached.

So, when the worst happens is your team resilient enough and sufficiently trained to respond effectively ? Are you confident your team can determine, for certain, whether critical data, such as customer information, or systems have been compromised so you can meet all the necessary compliance and reporting obligations? And do you have the network forensics in place that your SOC needs to be able to thoroughly investigate and respond to a breach?

In this episode of the Endace Packet Forensic files, I talk with RoseAnn Guttierrez, Technical Enablement Specialist BM at IBM Security and a former SOC analyst.

Rose shares her experience of what a day in the life of a SOC engineer is really like. She discusses the best practices she and her team put in place to manage the day-to-day challenges and improve their security posture. She also highlights some of the tools that were most valued in their daily operations and the critical importance of interoperability and integrated workflows to ensure efficiency and simplicity for SOC teams.

Rose discussed the challenge of balancing the need to provide reactive incident response versus having the time to devote to more proactive threat-hunting activities and suggests some approaches to better manage the balance between these important tasks. And she provides some suggestions and recommendations for SOCs on how to build maturity into processes, training, and effectiveness to improve security investigation capability.

Rose’s combination of SOC experience and deep knowledge of the security landscape has given her unique insight into the importance of having an interoperable ecosystem of tools and vendors that enables SOC teams to build resiliency and efficiency into their DNA.

In this episode of the Endace Packet Forensic files, I talk with Andrew Stewart, Senior National Security and Government Strategist at Cisco.  Andrew, CAPT, USN (Ret.) is a Senior Federal Strategist at Cisco where he implements strategies to support innovative cybersecurity and AI/ML solutions across the Federal Government.  He also served as the Commanding Officer and Program Manager at the Navy Cyber Warfare Development Group (NCWDG).

With Andrew’s deep experience in national security and government agencies, I wanted to get his thoughts on all the new Whitehouse mandates, and cybersecurity policies from CISA such as the emphasis on Zero Trust and other important initiatives.  We discuss whether what organizations are doing is sufficient given the risks posed by nation-state threat actors.

Noting that CISA guidelines and recommendations and Whitehouse mandates can help organizations and agencies prioritize cybersecurity with more urgency than before, Andrew raises the issue of awareness of cybersecurity among executives and corporate boards.  He suggests that, regardless of whether the threat is a nation-state attacker or a ransomware group, a threat-based approach is crucial. He also discusses the importance of building resilience across all “mission” functions, not just day-to-day operations, especially with a remote workforce.  In short,  security resilience is essential to underpin it all.

Lastly, Andrew highlights trends for the coming months – including the ever-changing nature of threats as hybrid cloud operating environments continue to expand the threat spectrum and transform the way we work. Visibility, he says, remains the key to mastering and controlling such a dynamic threat environment.

In the current era of extreme geopolitical instability, focus is intensifying on potential nation-state cyberthreats and how governments can defend against nation-states and cyber mercenaries. The increasing threat of nation-state led or sponsored attacks, combined with the massive potential impact of attacks on critical infrastructure are the stuff of nightmares that keep cyberdefenders up at night.

In this episode, I welcome back Justin Fier, VP Tactical Risk and Response at Darktrace (who was our very first guest in this series almost 40 episodes ago!) to talk about nation-state cyber, where he sees the threats lie, and what organizations can do to better prepare for possible attacks.

Justin talks about some of the great work being done by organizations like CISA, and the signs of increased collaboration between nation state defenders as being positive signs that things are moving in the right direction. But there are also significant challenges. Overcoming the slow pace of organizational change, addressing the dearth of skilled cybersecurity professionals, and building the agility to respond to the constantly evolving threat landscape are all major issues that we need to respond to as an industry – whether that’s in government defense or in securing the enterprise.

Lastly, Justin discusses what we need to do to better defend against nation-state and nation-state-sponsored attackers, and puts on his forecasting hat to predict what’s he sees as the most likely threats security teams should focus on over the next year or two.
