[RERELEASE] What is the perception of information security - part 2

In part two of this part two series Chris and I talk about security being a friendly face, the word hacker, and developers vs. security.

In part one of a two part series we talk about the perception of infosec in business, how we change it, and where security first in an organization.

Summary: In this episode, host Timothy De Block sits down with John Morello to dive into the world of Cryptography Bill of Materials (CBOM) and the looming transition to Post-Quantum Cryptography (PQC). They discuss why tracking cryptographic assets is becoming a critical security requirement, how CBOMs are being integrated into existing SBOM standards, and why organizations need to start future-proofing their encrypted data against quantum computing threats today. Key Topics Discussed What is a CBOM? A Cryptography Bill of Materials provides a trustworthy, structured, and machine-readable way to represent what cryptographic components exist in your software and how they are configured. Beyond the Basic SBOM: While a standard SBOM might tell you that a component like OpenSSL is present, a CBOM details the specific algorithms, key lengths, and operational modes in use. The Consolidation of Standards: CBOMs are actively being merged into broader SBOM frameworks like CycloneDX and SPDX. Over the coming months, CBOM data will simply become a subset of the tags and artifacts within standard SBOM files, reducing complexity for developers and security teams. The Post-Quantum Threat: The mathematical foundations of common encryption algorithms like RSA, DES, and SHA will eventually be defeatable by quantum computers. "Harvest Now, Decrypt Later": Adversaries may already be recording encrypted traffic today with the intention of decrypting it years down the line once quantum computing becomes viable. NIST and Regulatory Standards: NIST has been running a Post-Quantum Cryptography (PQC) project for several years and is expected to finalize approved algorithms soon. This guidance will likely be codified into future standards, such as a FIPS 140-4 update. Who Owns the CBOM? DevOps and developer teams should be responsible for creating and maintaining the CBOM data alongside their existing SBOM processes. Security teams will then consume this data to understand exposure, measure adoption of quantum-resistant algorithms, and prioritize risk mitigation.

Summary: Timothy De Block sits down with Casey Bleeker from SurePath AI to demystify the Model Context Protocol (MCP). They discuss how this emerging standard allows Large Language Models (LLMs) to interact with external tools and why it represents a significant, often invisible, exposure risk for enterprises. Casey explains why MCP should be viewed like the HTTP protocol—ubiquitous and fundamental—and outlines the critical security controls needed to prevent data exfiltration and malicious code execution without blocking AI adoption. Key Topics Discussed What is MCP? MCP is a standard for creating a "natural language definition" of an API, allowing an LLM to intelligently determine when to call a specific tool rather than just generating text. It acts as a translation layer between a REST interface and the AI model, enabling the model to execute tasks like updating a CloudFormation stack or querying a database. The "HTTP" Analogy & Exposure Risk: Casey argues that MCP should be thought of as a protocol (like HTTP) rather than a specific tool. It is being implemented broadly across many open-source tools and providers, often hidden behind the scenes when users add "connectors" or extensions. Because it functions as a protocol, it creates a broad exposure risk where users grant AI agents permissions to create, update, or delete resources on their behalf. Vulnerabilities to Watch for in the MCP: Malicious Payloads: Downloading an external MCP resource (e.g., via npm) can lead to unvalidated code execution on a local machine before the model even calls the tool. Data Exfiltration: Users effectively grant their identity permissions to untrusted code controlled by external third parties (the LLM), allowing the AI to act as a proxy for the user on internal systems. Defense Strategies: Central Management: Organizations need a central MCP management gateway authenticated via Single Sign-On (SSO) with role-based permissions to control which tools are authorized. Deep Payload Inspection: The only true control point is the interaction between the user/agent and the AI model. Security teams must inspect the payloads in real-time to steer usage away from unapproved resources or prevent destructive actions. Authentication Specs: DCR vs. CIMD: Casey warns against the Dynamic Client Registration (DCR) flow, citing complexity and vulnerabilities in many implementations. He highly recommends demanding vendors support the CIMD (Client-Initiated Management Data) specification, which allows for proper validation of destinations and enforces valid redirect URIs.

Summary: In this episode, host Timothy De Block dives into the often overlooked but critically important world of physical security with Josh Winter. Josh shares his unique journey from serving in combat infantry with the 82nd Airborne Division to running executive protection for high-net-worth individuals and conducting physical penetration testing for major corporations. They discuss the glaring differences between corporate security and residential security, how to spot the illusion of safety (like unplugged cameras and empty lobby desks), and why human behavior is always the most unpredictable variable in any security plan. Key Topics Discussed Josh's Background: How Josh transitioned from military service (82nd Airborne, PSD work in Afghanistan) to state security, executive protection for a wealthy family in San Diego, and eventually physical pen testing for a major firm. Corporate vs. Residential Security: The stark contrast between the static, often complacent environment of a corporate office and the highly dynamic, unpredictable nature of securing a private residence. The "Illusion of Security": Why lobby attendants without actual access control or security training are merely "decorations" and how unmonitored or broken cameras create a false sense of safety. Physical Pen Testing Tactics: Josh explains how simple confidence, observation, and exploiting human nature (like tailgating or holding the door) are often more effective than sophisticated hacking tools. The "Catch Me If You Can" Approach: How acting like you belong—much like Frank Abagnale Jr.—is the most powerful tool for bypassing physical security measures. Practical Security Upgrades on a Budget: Why $500 spent on motion-activated lighting, a simple ring camera, and upgraded door hardware is far more effective than a multi-million dollar system that isn't properly maintained. The Insider Threat: The reality that disgruntled employees, not shadowy hackers, often pose the greatest physical threat to an organization, and how to assess that risk. Security Culture: How to shift an organization's mindset so that challenging an unknown person in the hallway is seen as a sign of respect and vigilance, rather than rudeness.

Derek (@dth0m) has a lot of experience with SIEM and can be found on Linkedin participating in discussions on the technology. I had the opportunity to hang out with Derek at DerbyCon in 2015 and I came away impressed with his knowledge of SIEM. He seemed to be very passionate about the subject and that showed in this interview. We discuss: How to pronounce SIEM; what it is; how to use it; the biggest challenge; how to tune; and more.

Wolfgang has presented at many conference on the topic of threat modeling. He suggests using a much similar method of threat modeling that involves threat paths, instead of other methods such as a threat tree or kill chain. You can find him taking long walks and naps on Twitter (@jwgoerlich) and participating in several MiSec projects and events. In this interview Wolfgang covers: what threat modeling is; what needs to be done to get started; who should perform it; resources; and the lifecycle of a threat model.

Justin is a security and privacy research currently working on a project titled, "Mackerel: A Progressive School of Cryptographic Thought." You can find him on Twitter (@JustinTroutman) discussing ways in which crypto can be made easier for the masses. In the interview Justin talks about: what cryptography is; why everyone should care; some of its applications; and how to get started with cryptography.

Rafal Los is the Director of Solutions Research at Accuvant. He produces the Down The Security Rabbithole podcast and writes the Following the Wh1t3 Rabbit security blog. On several occasions he's tackled the CISO role within an organization on both his podcast and blog. I would highly recommend both if you're in the infosec field or looking to get into it. In the interview Rafal talks about: what a CISO is; the role of a CISO; the skills; and different types of CISOs.

Summary: In this episode, Timothy De Block sits down with cybersecurity expert Bob Lord to discuss the dangerous impact of "Hacklore"—obsolete, excessive, and fear-based cybersecurity advice. They explore how bombarding everyday users with spy-thriller scenarios (like juice jacking and evil baristas) leads to security fatigue and inaction. Instead, they advocate for shifting the burden of security away from the user and onto tech companies, while narrowing consumer advice down to the absolute basics: Multi-Factor Authentication (MFA), password managers, and credit freezes. Key Topics Discussed The Origins of Hacklore: Bob Lord started the Hacklore website after a CISO friend emailed him a "trifecta" of problematic security advice concerning public Wi-Fi, juice jacking, and restaurant QR codes. The initiative serves as an expert-backed resource to debunk common myths and promote better, actionable security guidance. Rethinking Security Advice: Providing users with excessive or overly complex advice often results in them ignoring it entirely. Security advice needs to be constantly reevaluated to ensure it addresses actual, common crimes rather than unlikely scenarios like an "evil barista" intercepting data. Shifting the Security Burden: The responsibility for digital safety should move away from the end-user and toward internet service providers and tech companies. Companies must adopt "secure by design" practices, such as requiring password changes upon installation or shipping routers with unique default passwords. The Power of MFA: Multi-Factor Authentication (MFA) is essential for protecting vulnerable populations, such as seniors who are frequently targeted by organized fraud. Even SMS-based MFA is far better than having no MFA at all, as it degrades most common attacks according to a Microsoft study. The Hidden Benefit of Password Managers: A major, underappreciated benefit of password managers is their built-in phishing resistance. If a user is tricked into visiting an imposter website, the password manager will not fill in the credentials, effectively stopping the attack in its tracks. Freezing Credit: Implementing a credit freeze is another highly recommended, fundamental security measure. This action builds directly on the basic security practices promoted by the Hacklore initiative. Learning from Near Misses: At the upcoming RSA conference, Bob Lord will discuss the concept of cyber security "near misses". He advocates that the cybersecurity field should learn from incidents that almost went wrong, similar to the safety approach used in the aviation sector. Memorable Insights Sharing obsolete security advice can be considered an "act of harm" because it distracts people from effective measures and can create a fatalistic mindset that no security action will help. Since most people will only dedicate a few minutes a year to security, recommendations must be strictly limited to what is truly feasible for them to implement. Getting a friend or family member to make just one security change, like enabling MFA on their primary email account, is considered a significant victory.
