Post-quantum encryption is already protecting real Internet traffic, but certificates, identity systems and software-signing chains are further behind. This October 2026 update examines what is actually protected, where classical cryptography remains trusted, and how security teams can verify deployed protection and prioritize the work ahead.

Understand non-human identities, why AI agents change their security risks, and how to review permissions, delegation,
approvals, and containment.

AI agents are no longer just passive tools—they hold credentials, access sensitive systems, and make autonomous decisions. That makes them a new class of insider risk. This article explores why Zero Trust, least privilege, continuous behavioral monitoring, and blast-radius containment are essential for governing increasingly capable AI systems.

A suspicious laptop is just the beginning. In this deep dive into a complex, contested investigation, we move beyond basic tool-use to explore 21 hard-learned lessons in DFIR. From navigating Windows 11 memory isolation to handling ‘denied access’ with professional integrity, learn how to state exactly what the evidence proves—and nothing more.

Quantum authentication and digital signatures have evolved from theoretical impossibility results to 504 km network demonstrations, paving the way for the quantum internet.

AI-native software development is changing the security model of the SDLC. As developers adopt AI coding assistants and autonomous agents, the attack surface expands beyond application code into prompts, model behavior, infrastructure-as-code, dependencies, and agent permissions. This deep dive examines how to secure the 2026 SDLC using policy-as-code, AI threat modeling, security automation, independent verification, prompt injection defenses, agent identity, and continuous behavioral testing.

Digital identity is no longer just a username, password, and login screen. In modern enterprises, identity is a full life cycle: provisioned through HR systems, authenticated with passkeys and risk signals, authorized through Zero Trust policies, monitored continuously, governed through IGA and PAM, and finally deprovisioned when access must end. This article breaks down the real journey of digital identity, from user onboarding to offboarding, and explains why identity has become the new security perimeter.

Web sessions are the invisible layer that keeps users logged in, preserves application state, and connects modern authentication flows across apps, identity providers, tokens, cookies, and SSO. This article explains how application sessions, IdP sessions, token renewal, secure logout, SPA architecture, and session hardening work together—and where poor design can lead to hijacking, CSRF, zombie sessions, or broken user workflows.

Autonomous AI agents introduce new security risks beyond traditional authentication and application security. This article explains how to build a multi-layered defense architecture using AI firewalls, guardrails, identity controls, RAG security, runtime tool protection, monitoring, and MITRE ATLAS-mapped detection.

Digital signatures are the foundation of modern digital trust, securing everything from TLS certificates and software updates to blockchain consensus and secure messaging. This article explores the evolution of digital signature schemes—from RSA, ECDSA, EdDSA, and Schnorr to NIST’s post-quantum standards (ML-DSA, SLH-DSA, and FN-DSA), BLS signatures, specialized constructions, and emerging quantum authentication—explaining their security assumptions, trade-offs, and real-world applications.
