Zero Trust isn't a new concept, but not one easily implemented. How do organizations transform cybersecurity from a "default allow" model, where everything is permitted unless blocked, to a "default deny" model?

Danny Jenkins, Co-founder and CEO at ThreatLocker, joins Business Security Weekly to discuss this approach. Deny by default means all actions are blocked by default, with only explicitly approved activities allowed. This shift enhances security, reduces vulnerabilities, and sets a new standard for protecting organizations from cyber threats. ‍ Danny will discuss how ThreatLocker not only protects your endpoints and data from zero-day malware, ransomware, and other malicious software, but provides solutions for easy onboarding, management, and eliminates the lengthy approval processes of traditional solutions.

The breaches will continue until appsec improves. Janet Worthington and Sandy Carielli share their latest research on breaches from 2024, WAFs in 2025, and where secure by design fits into all this. WAFs are delivering value in a way that orgs are relying on them more for bot management and fraud detection. But adopting phishing-resistant authentication solutions like passkeys and deploying WAFs still seem peripheral to secure by design principles. We discuss what's necessary for establishing a secure environment and why so many orgs still look to tools. And with LLMs writing so much code, we continue to look for ways LLMs can help appsec in addition to all the ways LLMs keep recreating appsec problems.

Default deny is an old, and very recognizable term in security. Most folks that have been in the industry for a long time will associate the concept with firewall rules. The old network firewalls, positioned between the public Internet and private data centers, however, were relatively uncomplicated and static. Most businesses had a few hundred firewall rules at most.

The idea of implementing default deny principles elsewhere were attempted, but without much success. Internal networks (NAC), and endpoints (application control 1.0) were too dynamic for the default deny approach to be feasible. Vendors built solutions, and enterprises tried to implement them, but most gave up.

Default deny is still an ideal approach to protecting assets and data against attacks - what it needed was a better approach. An approach that could be implemented at scale, with less overhead. This is what we’ll be talking to Threatlocker’s CEO and co-founder, Danny Jenkins, about on this episode. They seemed to have cracked the code here and are eager to share how they did it.

We wanted security data? We got it! Now, what the heck do we DO with all of it?

The core challenge of security operations, incident response, and even compliance is still a data management and analysis problem. Which is why we’re seeing companies like Abstract Security pop up to address some of these challenges.

Abstract just released a comprehensive eBook on security data strategy, linked below, and you don’t even need to give up an email address to read it! In this interview, we’ll talk through some of the highlights:

• Challenges
• Myths
• Pillars of a data security strategy
• Understanding the tools available

This week, it's double AI interview Monday!

In our first interview, we discuss how to balance AI opportunities vs. risk. Artificial Intelligence (AI) has the potential to revolutionize how businesses operate. But with this exciting advancement comes new challenges that cannot be ignored. For proactive security and IT leaders, how do you balance the need of security and privacy in AI with the opportunities that come with accelerating adoption?

Matt Muller, Field CISO at Tines, joins Business Security Weekly to discuss the unprecedented challenges facing Chief Information Security Officers (CISOs) and approaches to mitigate AI's security and privacy risks. In this interview, we'll discuss ways to mitigate AI's security and privacy risks and strategies to help ease AI stress on security teams.

Segment Resources: - https://www.tines.com/blog/cisos-report-addressing-ai-pressures/ - https://www.tines.com/blog/ai-enterprise-mitigate-security-privacy-risks/

In our second interview, we dig into the challenges of securing Artificial Intelligence. Are you being asked to secure AI initiatives? What questions should you be asking your developers or vendors to validate security and privacy concerns?

Who better to ask than Summer Fowler, CISO at Torc Robotics, a self-driving trucking company. Summer will guide us on her AI security journey to help us understand:

• Regulatory requirements regarding AI
• Build vs. buy decisions
• Security considerations for both build and buy scenarios
• Resources to help guide you

We have a top ten list entry for Insecure Design, pledges to CISA's Secure by Design principles, and tons of CVEs that fall into familiar categories of flaws. But what does it mean to have a secure design and how do we get there? There are plenty of secure practices that orgs should implement are supply chains, authentication, and the SDLC. Those practices address important areas of risk, but only indirectly influence a secure design. We look at tactics from coding styles to design councils as we search for guidance that makes software more secure.

When we use the phrase "talent gap" in cybersecurity, we're usually talking about adding headcount. For this interview, however, we're focusing on a gap that is evident within existing teams and practitioners - the often misunderstood soft skills gap.

Side note: I really hate the term "soft skills". How about we call them "fundamental business skills", or "invaluable career advancement skills"? Hmm, doesn't quite roll off the tongue the same.

Soft skills can impact everything, as they impose the limits of how we interact with our world. That goes for co-worker interactions, career advancements, and how we're perceived by our peers and community. It doesn't matter how brilliant you might be - without soft skills, your potential could be severely limited.

Did you know that soft skills issues contributed to the Equifax breach?

We'll also discuss how fear is related to some of the same limitations and challenges as soft skills.
