🔐 Microsoft Deputy CISO Ilya Grebnov outlines practical steps to make opportunistic cyberattacks harder by design. He emphasizes credential elimination using managed identities and federated tokens, paired with endpoint reduction to move services off the public internet. The article further advocates platform engineering—paved paths, policy-as-code, and centralized core services—to enforce consistent secure defaults and reduce the attack surface at scale.

🔎 Supply chain dependencies create hidden cyber blind spots that can cascade into large-scale operational, financial, and reputational damage. Many SMBs underestimate the threat — ESET’s 2026 SMB Cyber Readiness Index shows supply chain attacks rank well below concerns about AI-powered malware. High-profile incidents (3CX, CDK, Change Healthcare, Jaguar Land Rover) and erroneous updates (CrowdStrike) show risk from both malice and error. The author advises mapping third-party dependencies, enforcing vendor cybersecurity standards, and adopting zero trust and continuous monitoring.

🔒 Organizations must treat AI as part of their core architecture rather than a separate stack. Effective protection extends existing controls — identity, policy enforcement, observability, and data governance — across AI interfaces, private LLMs, and agentic systems. Security requires coordinated runtime enforcement at firewalls, API gateways, and SIEM with zero-trust principles. Fortinet positions converged platforms as the way to embed AI guardrails into the foundational operating model.

🛡️The article examines the multilayered fortifications of Constantinople, describing four concentric defensive lines that created an imposing, nearly unscalable barrier. It details structural elements — a 15–20 m wide brick-lined ditch often flooded, a low breastwork for firing, an 8 m outer wall with 82 towers, and a 12 m main wall with 96 offset towers — and the broad terraces between them. Taken together, these features illustrate a medieval example of defense-in-depth applied through successive engineered obstacles.

🔐 This sponsored article from Specops Software explains five practical ways Zero Trust reduces identity-related risk by centering access controls on verified identities and device posture. It emphasizes least privilege, continuous context-aware authentication tied to device health, and strict segmentation to limit lateral movement. The piece spotlights Specops Device Trust as an example of binding identity to compliant devices and recommends prioritizing phishing-resistant MFA and device checks when starting a Zero Trust rollout.

🔒 Cloudflare Mesh provides a developer-friendly private network that unifies access for users, devices, and AI agents across clouds and the Cloudflare edge. Integrated with Cloudflare One, Mesh uses the Cloudflare One Client and Mesh nodes to route bidirectional, many-to-many traffic with built-in Gateway policies, DNS filtering, device posture checks, and DLP. It supports Workers VPC bindings and the Agents SDK so serverless agents and Durable Objects can securely reach private services, with a free tier for up to 50 nodes and 50 users.

🔒 UCR partnered with Google Public Sector to build a Secure Enclave powered by the Stellar Engine, a preconfigured cloud container that automates and enforces rigorous security postures. Backed by Google Cloud’s accredited services and a Zero Trust architecture, the environment closes unnecessary access points and maps foundational controls for NIST SP 800-171 and CMMC Level 2. The result is reduced technical overhead for researchers, restored eligibility for sensitive federal grants, and a scalable model the university plans to share with peers.

🔒 Organizations often implement strong identity and access controls but miss enforcement at the traffic layer. During incidents these gaps—across ingress paths, load balancers, CDNs, and APIs—allow traffic to bypass identity checks. Common failures include weak TLS and cipher baselines, fragmented ingress, and half‑implemented mutual TLS. Effective programs treat traffic handling as the primary enforcement point through standardized ingress, request normalization, and consistent end-to-end telemetry.

🔐 Google has made Device Bound Session Credentials (DBSC) generally available to Windows users on Chrome 146, with macOS support planned for a later release. DBSC uses hardware-backed modules like the Trusted Platform Module (TPM) to bind short-lived session cookies to a specific device so exfiltrated cookies cannot be used by attackers. The feature falls back gracefully on devices without secure key storage and was developed with Microsoft as part of efforts to make the approach an open web standard. Google says the architecture is privacy-minded and does not enable cross-site tracking.

🔐 Google has introduced Device Bound Session Credentials (DBSC) protection in Chrome 146 for Windows to block infostealer malware from harvesting session cookies. The feature cryptographically ties session cookies to hardware-backed keys stored in the Trusted Platform Module (TPM) on Windows, with macOS support planned for a future release. Because the per-session private keys are generated by a security chip and cannot be exported, exfiltrated cookies become useless without proof of key possession. The protocol is privacy-conscious, uses distinct keys per session to avoid cross-site correlation, and was developed with industry input including Microsoft.

🔐 Chrome has enabled Device Bound Session Credentials (DBSC) publicly for Windows users on Chrome 146, with macOS support arriving in a future release. DBSC cryptographically binds short‑lived session cookies to a device's hardware-backed key (TPM or Secure Enclave) so exfiltrated cookies cannot be reused off‑device. The browser handles rotation and the approach preserves privacy by avoiding device identifiers. Web developers can adopt DBSC via the open spec and developer guide.

🔒 Supply chain attacks now bypass traditional defenses by exploiting trusted vendors, open-source components, cloud services, and MSP tools, creating cascading impact across distributed environments. Map and inventory all dependencies, classify them by criticality, and continuously evaluate supplier posture using SBOMs, patch cadence, and incident response readiness. Apply Zero Trust controls: MFA, least privilege, segmentation, and just-in-time access, and centralize unified telemetry across endpoints, identity, network, email, and backups to detect anomalies faster. Finally, design recovery playbooks, immutable backups, and automated restore testing to shorten downtime when compromise occurs.

🔒 APIs are increasingly the enterprise perimeter, and recent breaches show traditional protections often miss API-layer abuse. Security teams report attacks that exploit business logic or use stolen credentials, which EDR and WAF tools can treat as legitimate traffic. CISOs are adopting API governance, centralized inventories, identity-aware access controls, and API gateways integrated into CI/CD to enforce least-privilege and reduce misconfiguration risk. As agentic AI and automated agents proliferate, stronger token handling, credential rotation, and real-time behavioral monitoring are becoming essential.

🔒 The perimeter model has broken down as workforces go hybrid, and many Zero Trust deployments miss a key link between identity and session authorization. Specops Device Trust argues that authentication must be contextualized with real-time device posture checks to prevent token theft and session hijacking. Binding identity to a verified device and continuous monitoring lets organizations enforce dynamic, low-friction policies that reduce risk.

🔒 This post explains AWS IAM policy types and how to apply them in a multi-account environment. It describes identity-based and resource-based policies, permissions boundaries, service control policies (SCPs), and resource control policies (RCPs), with ownership guidance for central security and application teams. Using a practical multi-account example, it shows how to combine these controls to enforce least privilege and protect data while enabling team autonomy. It also recommends policy validation and provides sample code.

🔒 Microsoft announced Zero Trust for AI, extending proven Zero Trust principles across the AI lifecycle and shipping new tools and guidance to help security teams deploy AI with confidence. The update adds an AI pillar to the Zero Trust Workshop, expands the Zero Trust Assessment to include Data and Networking, and introduces a Zero Trust for AI reference architecture. Microsoft also published practical patterns for threat modeling and AI observability to help teams verify agents, apply least privilege, and assume breach.

🔒 Iranian-aligned threat actors are shifting from bespoke destructive wipers to weaponizing privileged identities and native management features. Rather than deploying novel binaries, attackers compromise high-privilege accounts and use legitimate MDM/RMM or cloud consoles to push remote-wipe and factory-reset commands at scale. This living-off-the-land approach bypasses traditional endpoint telemetry and enables rapid, high-impact disruption across managed tenants. Defenders must prioritize identity resilience, Zero Trust, and immutable backups to maintain survivability.

🔁 Cloudflare and CDW present a pragmatic, phased approach to migrate from legacy VPNs to a SASE-based Zero Trust architecture, prioritizing coexistence over disruptive cutovers. Their methodology uses a risk-aware, tiered application classification and Cloudflare Access wrapping to add SSO, MFA, and outbound-only tunnels without rewriting legacy code. The approach couples a pre-migration audit with staged pilots and dual-client rollouts to preserve service continuity and provide rollback paths.

🔒 The article argues the cyber perimeter was never dead but was abandoned, leaving unsupported firewalls, routers, and remote access appliances as easy footholds for attackers. It outlines the FBI’s Operation Winter SHIELD, a concentrated two-month effort targeting weak authentication, excessive privileges, and unpatched edge devices, and CISA’s BOD 26‑02, which mandates removal of end-of-life perimeter hardware within 18 months. The piece warns that neglecting edge devices undermines identity-first strategies and urges CISOs to regain total edge visibility and enforce disciplined asset lifecycles, strong hardware-based authentication, rapid patching, and strict privilege controls.

⚠️ Zero trust principles deliver measurable gains in enterprise IT, but they often miss dominant failure modes in IoT and OT. The author argues that zero trust assumes explicit, identity-centric and continuously enforceable trust, while IoT/OT systems rely on implicit, durable trust relationships and centralized control paths. Adopt the unified linkage model (ULM) to map adjacency, inheritance and trust propagation, and prioritize protection of management planes, firmware update paths and vendor integrations.
