🔒 Remote Privileged Access Management (RPAM) provides a cloud-native approach to securing privileged accounts beyond traditional perimeters, enabling administrators, contractors and third-party vendors to connect securely from any device or location. RPAM enforces least-privilege, Just-in-Time access and multi-factor authentication while recording detailed session logs without relying on VPNs. By supporting zero-trust principles and scalable deployments, RPAM reduces attack surface and streamlines compliance.

🔒 This article identifies seven security practices that have become obsolete in modern, cloud-first and hybrid workplaces. Contributors including Amit Basu, George Gerchow and others warn against relying on perimeter defenses, legacy VPNs, SMS-based 2FA and on-premises SIEMs, and caution about overreliance on EDR or compliance-only programs. It recommends shifting to Zero Trust, SASE, continuous monitoring and active security awareness to close visibility gaps and reduce risk.

🔒 Telecom operators must abandon perimeter assumptions and adopt a zero trust mindset that treats verification as continuous rather than a one-time event. This shift is organizational as much as technical, requiring unified IT/OT policies, least-privilege access and microsegmentation to limit lateral movement. The article recommends pragmatic steps — wrapping legacy systems with secure gateways and centralized authentication — and aligning controls with frameworks such as NIST and NIS2, while tracking concrete KPIs in the first 180 days.

🔐 Multicloud adoption improves flexibility but introduces security and visibility risks unless managed centrally. Establish a central authority to define strategy, enforce policies and select cross-cloud tools, while implementing unified governance backed by identity management and automation. Treat every environment as a single trust boundary, enforce least privilege, and correlate telemetry for a unified detection-and-response posture. Limit access with short-lived sessions, recording and DLP to reduce attack surface and support auditability.

🔐 Passwork 7 consolidates enterprise password and secrets management into a single, self-hosted platform supporting both human and machine credentials. The release improves credential organization with new vault types, expands RBAC and group-based permissions, and enhances audit trails and notifications. It also provides a REST API, Python connector, CLI, and Docker image for automation, plus zero-knowledge encryption and SSO/LDAP integration to help meet compliance needs.

🔒 Samsung Galaxy devices with Knox Suite combine hardware-rooted protections and centralized management to help IT secure corporate data without slowing users. Built-in at manufacture, Knox delivers multi-layered defenses—secure boot, trusted execution environments, and integrated malware protections—while fitting into existing EMM workflows. Native Zero Trust support, ZTNA and near-real-time telemetry from Knox Asset Intelligence feed SIEMs so mobile threats are visible alongside other alerts.

🔒 Ringfencing, or granular application containment, enforces least privilege for authorized software by restricting file, registry, network, and interprocess access. It complements allowlisting by preventing misuse of trusted tools that attackers commonly weaponize, such as scripting engines and archivers. Effective rollout uses a monitoring agent, simulated denies, and phased enforcement to minimize operational disruption. Properly applied, containment reduces lateral movement, blocks mass exfiltration and ransomware encryption while preserving business workflows.

🔒 Arista Networks and Palo Alto Networks extended their partnership to deliver a framework for zero-trust inside the data center. The integration pairs Arista’s Multi-Domain Segmentation Services (MSS) fabric and full network visibility with Palo Alto’s next-generation firewall (NGFW) to enable an inspect-once, enforce-many model. CloudVision MSS supports dynamic quarantine and can offload trusted high-bandwidth 'elephant flows' after inspection, while the NGFW triggers hardware line-rate isolation when threats are detected. Unified policy orchestration and Arista Validated Designs (AVD) with AVA automation add network-as-code and CI/CD-friendly deployment so NetOps and SecOps can scale independently.

🔒 AWS has expanded AWS IoT Core, AWS IoT Device Management, and AWS IoT Device Defender to support VPC endpoints via AWS PrivateLink and IPv6 for both VPC and public endpoints. Developers can route data plane operations, management APIs, and credential requests entirely within VPCs, keeping traffic off the public internet. Configuration is available through the AWS Management Console, AWS CLI, and CloudFormation, and the features are GA in all Regions that offer these services.

🔒 The Model Context Protocol (MCP) enables AI agents to connect to data sources, but early specifications lacked robust protections, leaving deployments exposed to prompt injection, token theft, and tool poisoning. Recent protocol updates — including OAuth, third‑party identity provider support, and an official MCP registry — plus vendor tooling from hyperscalers and startups have improved defenses. Still, authentication remains optional and gaps persist, so organizations should apply zero trust and least‑privilege controls, enforce strong secrets management and logging, and consider specialist MCP security solutions before production rollout.

🔒 AWS announced an independent affirmation of the Amazon EKS zero operator access design, validated by cybersecurity firm NCC Group. The review found no architectural gaps and confirmed that AWS personnel lack technical means to access or manipulate customer content in managed Kubernetes control planes or etcd backups. AWS highlights Nitro-based confidential compute, tightly scoped administrative APIs with multi-party change approval, mandatory logging and auditing, and envelope encryption for etcd as core protections. Customers retain visibility via cluster audit logs and remain responsible for securing worker node configurations outside managed modes.

🔐 As enterprises deploy AI assistants and autonomous agents, existing security frameworks must evolve to treat these agents as first-class identities rather than afterthoughts. The piece advocates applying Zero Trust principles—identity-first access, least-privilege, dynamic contextual enforcement, and continuous monitoring—to agentic identities to prevent misuse and reduce attack surface. Practical controls include scoped, short-lived tokens, tiered trust models, strict access boundaries, and assigning clear human ownership to each agent.

🔒 Prisma SASE positions Prisma SD‑WAN and Prisma Access as a unified blueprint for securing modern branch offices, embedding zero trust and local enforcement into the branch edge. It emphasizes identity‑aware controls (User‑ID, Device‑ID, App‑ID), automated IoT discovery and on‑box protections like URL filtering and DNS security to reduce appliance sprawl and contain lateral movement. By pairing on‑device enforcement with cloud services and centralized management via Strata Cloud Manager, the solution aims to simplify operations, maintain consistent policies and keep defenses up to date across distributed locations.

🔐 CISA, the NSA and international partners have published the Microsoft Exchange Server Security Best Practices to help organisations reduce exposure to attacks against hybrid and on‑premises Exchange deployments. The guidance reinforces Emergency Directive 25-02 and prioritises restricting administrative access, enforcing multi‑factor and modern authentication, tightening TLS and transport security, and applying Microsoft's Exchange Emergency Mitigation service. It also urges migration from unsupported or end‑of‑life systems and recommends use of secure baselines such as CISA's SCuBA. Agencies stress ongoing collaboration and a prevention-focused posture despite political and operational challenges.

🔒 Today's complex IT environments — multi-cloud, hybrid work, and AI — have expanded the attack surface, exposing limits of fragmented point solutions. The article argues that unifying networking and security on a natively integrated platform like VersaONE reduces blind spots, enforces consistent policies, and enables real-time threat detection and automated response using built-in AI. With zero trust access and microsegmentation, the platform aims to minimize lateral movement and simplify operations compared with bolt-together or 'platformized' vendor offerings.

🔐 Cloudflare presents a privacy-first approach to rate-limiting AI agents using anonymous credentials. The post explains how schemes such as ARC and ACT extend the Privacy Pass model by enabling late origin-binding, multi-show tokens, and stateful counters so origins can enforce limits or revoke abusive actors without identifying users. It outlines the cryptographic building blocks—algebraic MACs and zero-knowledge proofs—compares performance against Blind RSA and VOPRF, and demonstrates an MCP-integrated demo showing issuance and redemption flows for agent tooling.

🔐 Today, CISA, in collaboration with the National Security Agency and international partners, published Microsoft Exchange Server Security Best Practices to help defenders harden on-premises Exchange servers against ongoing exploitation. The guidance emphasizes strengthening user authentication and access controls, enforcing robust network encryption, and reducing application attack surfaces through configuration and feature management. CISA also urges organizations to decommission end-of-life or hybrid 'last Exchange' servers after migrating to Microsoft 365 to reduce exposure to continued exploitation.

🔒 CISA, the NSA, and international partners released the Microsoft Exchange Server Security Best Practices blueprint to help administrators of on‑premises and hybrid Exchange environments strengthen defenses against persistent cyber threats. The guidance builds on CISA’s Emergency Directive 25‑02 and emphasizes restricting administrative access, implementing multifactor authentication, enforcing strict transport security, and adopting zero trust principles. It also urges organizations to remediate or replace end‑of‑life Exchange versions, apply recommended mitigations, and consider migrating to cloud-based email to reduce operational complexity and exposure.
