Not all vulnerabilities can be patched right away, and in these cases, compensating controls, segmentation, and exceptions become essential components of a realistic remediation strategy. In this episode, we discuss how organizations can use host firewalls, access control lists, and network isolation to contain vulnerable systems while planning for a longer-term fix. We also explore how to formally document and justify exceptions when remediation is deferred—something often required for compliance audits. These exceptions should include timelines, risk assessments, and mitigating measures to...

Auditing is how security teams verify that controls are working, policies are being followed, and no one is operating outside expected behavior—and in this episode, we explore both system and process auditing in depth. System audits focus on configurations, permissions, and change logs—ensuring that operating systems, devices, and applications remain in a secure, known state. Process audits, on the other hand, examine whether organizational practices—like onboarding, patching, or incident response—are aligned with documented procedures and regulatory requirements. We explain how to ...

In this final installment on architectural considerations, we focus on risk transference, ease of recovery, and the practical realities of patch availability and compute resources. Risk transference involves shifting some security or operational responsibilities to third parties—such as cloud providers, insurers, or managed service vendors—through contracts or service-level agreements (SLAs). While this can offload liability, it must be done with clear understanding of what remains within your control and what doesn’t. Ease of recovery is equally essential, involving strategies like ...

Availability is one of the core tenets of cybersecurity, and in mission-critical environments, downtime is simply not an option. In this episode, we focus on high availability (HA) architectures—design strategies that ensure systems remain operational even when components fail. We examine techniques like clustering, load balancing, redundancy, failover mechanisms, and geographic dispersion, all of which contribute to resilience and uptime. We explain the difference between active-active and active-passive configurations, how to plan for single points of failure, and why HA should be part of ...

As powerful as automation is, it’s not without challenges—and in this episode, we dive into the complexity and cost considerations that come with security automation projects. Poorly scoped automation can introduce more problems than it solves, especially when it relies on fragile scripts, inconsistent APIs, or tools that don’t integrate cleanly. We explore how hidden costs—such as testing time, support, licensing, and training—can derail budgets and delay ROI if not planned from the start. Complexity grows quickly as automation touches more systems, requiring orchestration tools, ...

Securing infrastructure starts with design decisions about where and how devices are placed, how data flows, and where trust boundaries begin and end. In this episode, we focus on device placement and network zoning, exploring how separating front-end, back-end, and management traffic can prevent attackers from using one compromised segment to access others. Concepts like jump servers, demilitarized zones (DMZs), and out-of-band management networks help isolate critical systems and limit exposure. We also discuss attack surface reduction by minimizing the number of internet-facing devices and ...

Not all protocols are created equal—and using the wrong one can open a serious security hole in your environment. In this episode, we examine the implementation of secure communication protocols like TLS, SSH, and IPSec, which provide confidentiality and integrity for data in transit. We explain how these protocols differ from insecure alternatives like Telnet, HTTP, and FTP, and why default configurations often need to be hardened to ensure true protection. Topics include cipher suite selection, certificate management, forward secrecy, and secure key exchange—all of which play a role in ...

Security begins with visibility, and that means knowing what devices, systems, and software exist within your environment at all times. In this episode, we dive into asset monitoring and tracking, emphasizing the importance of real-time discovery tools, agent-based scanning, and centralized asset inventories that support security monitoring, patch management, and incident response. We also explore challenges like shadow IT—unauthorized systems that operate outside governance—and how to close visibility gaps in hybrid and cloud environments. Automated inventory systems help detect new ...

Security doesn’t start when a system is installed—it begins during the procurement process. In this episode, we examine how secure acquisition strategies reduce long-term risk by vetting vendors, establishing supply chain transparency, and embedding cybersecurity requirements in contracts and service-level agreements (SLAs). We discuss how organizations should assess the security posture of suppliers, request evidence of internal controls or compliance certifications, and evaluate whether vendors follow secure development and patching practices. For hardware, this includes checking ...

Once risks are identified and analyzed, organizations must decide how to respond—and in this episode, we examine the five primary risk management strategies: mitigate, transfer, accept, avoid, and exempt. Mitigation involves applying controls to reduce risk impact or likelihood, such as enabling MFA or installing endpoint protection. Transferring risk often involves insurance or outsourcing functions to vendors with specialized capabilities and contractual safeguards. Acceptance applies when the cost of mitigation outweighs the threat, provided the risk is well understood and formally ...

Preparation is only as good as its ability to withstand the unexpected, and resilience testing is how you find out whether your systems, processes, and people are truly ready. In this episode, we explore the value of comprehensive testing methods such as tabletop exercises, simulated failovers, load tests, and real-world attack scenarios. Tabletop exercises walk teams through incident response steps in a controlled environment, helping validate decision-making, communications, and escalation procedures. Simulated failovers test high availability systems and backup infrastructure to ensure ...

Building on the first part of our automation series, this episode explores how security automation improves scalability, incident reaction time, and team productivity. We examine real-world examples where automated alerts trigger isolation of infected systems, revoke compromised credentials, or update firewall rules within seconds—long before a human analyst could intervene. Automation enables systems to scale securely by enforcing templates, access policies, and configuration baselines across hundreds or thousands of assets, even in fast-moving cloud environments. We also touch on workforce...

Remote and hybrid work models create new layers of security complexity—blending corporate environments with home networks, personal devices, and cloud-first workflows. In this episode, we explore the core topics of remote work security awareness, starting with safe home Wi-Fi configurations, strong authentication, and VPN use for secure connections. We then discuss endpoint hardening for laptops and mobile devices, including encryption, screen locking, and secure backup practices. Hybrid workers also need guidance on physical security—like preventing shoulder surfing in public places or ...

Monitoring is the heartbeat of any modern security operation, providing real-time visibility into systems, applications, and infrastructure. In this episode, we explore how organizations monitor computing resources for both performance and security, using tools like agents, collectors, log forwarders, and telemetry APIs. We discuss the difference between host-based and network-based monitoring, and how to build a centralized view through Security Information and Event Management (SIEM) platforms. The focus is on both proactive and reactive monitoring—identifying anomalies before they become ...

Data is not monolithic—its classification and context determine how it should be secured. In this episode, we explore different types of data, including regulated data like personal health information (PHI), payment card information (PCI), and personal identifiable information (PII), as well as trade secrets, intellectual property, and public-facing information. Each type has different legal, operational, and reputational implications if exposed or altered, and thus requires tailored protection strategies. We examine how data classification schemes—ranging from "public" and "internal" to "...

A growing portion of cybersecurity risk now comes from outside the organization—specifically, through third-party vendors, suppliers, and service providers. In this episode, we examine how to assess and manage vendor risk across the full lifecycle, starting with due diligence during procurement and continuing through onboarding, monitoring, and offboarding. We explore how to evaluate vendors based on their security policies, compliance certifications, breach history, and contract terms—especially service-level agreements (SLAs) and right-to-audit clauses. Supply chain security goes beyond ...

Applications are often the most exposed layer of an organization’s attack surface, and defending them requires both proactive development practices and reactive protection mechanisms. In this episode, we review essential application security concepts including input validation, secure cookie handling, and session management to prevent injection attacks, cross-site scripting (XSS), and session hijacking. We also examine the importance of static code analysis during development, code signing to verify integrity, and the use of secure development lifecycle (SDLC) frameworks to build security ...

Security must adapt to the architecture of the environment it protects, and that starts with understanding how infrastructure is organized. In this episode, we compare on-premises, centralized, and decentralized architectures, explaining the security implications of each. Centralized models offer streamlined control, simpler updates, and more consistent enforcement—but they also concentrate risk in a single point of failure. Decentralized architectures distribute resources and decision-making, improving resilience but making visibility, auditing, and access management more complex. On-prem ...

Monitoring is most valuable when it drives action, and in this episode, we explore foundational activities that turn data into defense—starting with log aggregation, alerting, and scanning. Log aggregation involves collecting logs from diverse systems—servers, firewalls, applications, cloud platforms—into a central platform for correlation and analysis. Alerting systems evaluate these logs in real time, flagging deviations from normal behavior based on thresholds, signatures, or heuristics. We also examine the importance of routine vulnerability scanning to proactively identify ...
