AI observability: How CIOs can see past their org blind spots

The article discusses AI observability, highlighting how traditional IT monitoring tools are insufficient for evaluating artificial intelligence performance. As AI applications expand across modern businesses, CIOs frequently struggle with deep blind spots regarding system usage, model drift, performance degradation, and unauthorized "shadow AI" tools. Unlike standard software that relies on predictable metrics like uptime, AI systems operate probabilistically, meaning the exact same inputs can yield wildly varying outcomes. This inherent unpredictability creates compounding risks, especially as enterprises connect multiple autonomous agents into complex workflows where minor data issues can quietly corrupt downstream results for weeks before finally breaking. To address these organizational vulnerabilities, experts suggest shifting from front-loaded risk assessments to continuous, full-stack visibility. This comprehensive approach involves setting up automated guardrails for model outputs, maintaining a clear catalog of active systems, and establishing an integrated control plane. By compiling system telemetry, semantic mapping, and risk thresholds into a single shared interface, different corporate stakeholders, such as finance, human resources, and security teams, can easily monitor the metrics relevant to their own departments. Ultimately, treating observability as a core design principle rather than an afterthought enables leadership to safely scale their AI initiatives, manage ballooning costs, and build lasting organizational trust.


The Validation Gap Is Costing You More Than You Think

According to a report on software delivery, development teams are writing more code than ever, but less of it is actually reaching production. Analysis of millions of workflows reveals that while development throughput has spiked, main branch success rates have fallen to a five-year low of roughly seventy percent. This drop stems from a gap in how software is validated. Traditional continuous integration systems were designed for humans who commit code gradually. Today, automated artificial intelligence tools generate code at a rapid pace that completely overwhelms traditional review processes. When errors are caught late in the shared integration system, it results in expensive compute costs, wasted time, and broken focus as the automated tools have already moved on to other tasks. To solve this dilemma, engineering teams must shift testing much earlier into the initial writing phase. By running smaller, targeted tests while the automated code generator is still actively focused on a task, teams can fix errors immediately without draining infrastructure resources. When this early testing stage and the final integration pipeline share historical information, the entire delivery system becomes smarter and more efficient. Ultimately, addressing this validation imbalance helps organizations safely increase their software output without absorbing downstream failures.


Why Attack Surface Management Breaks in OT (and What Actually Works)

Traditional Attack Surface Management (ASM) fails in Operational Technology (OT) environments because industrial infrastructure operates on fundamentally different principles than standard enterprise IT systems. Many legacy industrial protocols, such as Modbus, DNP3, and BACnet, were created decades ago without built-in encryption, session management, or authentication mechanisms. Consequently, their lack of security is an inherent property of the system design rather than a simple configuration mistake that can easily be patched. Furthermore, the active interrogation techniques standard in IT security can severely disrupt operational networks; sending aggressive probes often overwhelms the limited network stacks of Programmable Logic Controllers (PLCs), causing critical physical machinery to misbehave or shut down entirely. Because these industrial environments do not support software agents or standard diagnostic queries, establishing a reliable asset inventory is remarkably difficult. To mitigate risks effectively, security teams must reverse their usual enterprise instincts by defaulting to passive network monitoring and treating active probing as a tightly managed privilege. Utilizing passive internet search data allows analysts to map exposed external components safely without introducing disruptive traffic to live plants. Ultimately, embedding clear safety workflows and strict rate limits into automated security tools ensures that scanning efforts do not cause unintended physical operational downtime.


Backup and recovery architecture best practices for UK SMEs

The Security Boulevard article explains that smaller businesses in the UK should treat backup and recovery as a practical safety measure rather than a simple file storage task. A sensible backup plan focuses entirely on restoration outcomes, ensuring a company can keep trading after an incident like an accidental deletion, system failure, or cyberattack. Instead of buying expensive software tools first, these organizations should prioritize their systems based on how a disruption directly impacts their daily operations, clearly defining how much downtime and data loss they can realistically handle. To build stronger protection, companies must keep multiple copies of their files across separate locations and accounts so that a single compromise or mistake cannot destroy both the live data and the backups. Furthermore, restricting access to named administrative accounts, applying settings that prevent recent copies from being altered or deleted, and choosing backup styles that match different types of systems will lower overall risk. Because copying data does not automatically mean a system can be successfully rebuilt, regular testing is necessary to catch unexpected delays and overlooked technical connections. Ultimately, the article recommends documenting these steps in short, straightforward guides with clear ownership so that staff can respond calmly when an unexpected outage occurs.


Challenging AI Assumptions

In his Forbes article, John Werner encourages readers to reconsider common assumptions about artificial intelligence that might limit our ability to effectively navigate the future. He notes that early technology milestones, such as the IBM Watson era, conditioned the public to view machine intelligence as a centralized database focused entirely on factual recall, rapid calculation, and deterministic logic. However, as the field quickly moves toward a future centered on autonomous software agents, Werner argues that continuing to rely on these old centralized frameworks is a foundational mistake. Drawing from insights shared at a recent MIT-linked conference, he suggests that the true development of artificial intelligence will ultimately mirror biological organisms and complex economic networks rather than centralized computer hardware. Because the long-term impact of this technology on global society is frequently compared to foundational discoveries like fire or electricity, our structural approach must evolve accordingly. Instead of designing isolated, top-down systems, we should foster collaborative, decentralized, and biologically inspired ecosystems of digital agents. By shifting our perspective away from rigid central control, human society can establish cooperative frameworks that allow these increasingly autonomous systems to be integrated smoothly, sustainably, and safely into everyday life.


The Architecture Questions I Ask Before an Initiative Starts

In his article, Eetu Niemi outlines three practical architectural questions to ask before any major business project begins, aiming to clarify scope and prevent costly downstream surprises. The first question focuses on what is actually changing within the organization. Project names can often be deceptive, so teams must carefully distinguish between a project's stated scope and its actual, wider impact. If a change only alters a single isolated system, heavy architectural planning is rarely needed. The second question addresses visible dependencies, identifying which software applications, data streams, teams, or external vendors the project relies upon. Uncovering this scattered knowledge early helps avoid scheduling or financial surprises down the line without over-documenting every minor connection. The final question evaluates which decisions would be expensive to reverse later on. While choices regarding technology platforms, data models, or core software might seem like minor delivery choices initially, they quickly harden into fixed constraints once other systems are built around them. By addressing what is changing, identifying dependencies, and flagging irreversible choices early on, architects can guide decision-making through plain conversations and basic diagrams. This upfront evaluation allows organizations to balance development speed with long-term operational stability without drowning teams in unnecessary paperwork or rigid governance structures.


Building a Quantum-Safe Foundation: WWT and Cisco Accelerate Post-Quantum Readiness

The article outlines how World Wide Technology and Cisco are working together to help organizations secure their networks against future quantum computing threats. Central to this effort is the use of Cisco 8000 Series Secure Routers, which address post-quantum security in two main areas: protecting data in transit with encryption that resists quantum attacks, and maintaining internal device integrity through hardware-anchored trust and secure boot processes. Importantly, these routers already contain the necessary hardware components to run these new cryptographic standards, meaning companies do not need to replace their existing infrastructure and can implement the updates through straightforward configuration changes. This compatibility allows quantum-safe equipment to run on the same network as older systems, removing the need for a risky, immediate complete network overhaul. To guide organizations through this transition, World Wide Technology provides planning and deployment support through its specialized security division and its Advanced Technology Center lab facility. In this testing lab, engineering teams can evaluate encryption tunnel behaviors and test fallback systems under realistic network conditions before rolling them out. Ultimately, the collaboration highlights that achieving security against quantum threats is an ongoing program requiring careful testing, technical depth, and phased adjustments rather than a simple product purchase.


The Next Wow Factor: A Conversation with Sidney Lu, Chairman and CEO, Foxconn Interconnect Technology (FIT)

In this interview, Sidney Lu, the chairman and chief executive officer of Foxconn Interconnect Technology, reflects on his forty year career and personal leadership philosophy. He oversees a large global workforce that manufactures vital electrical parts, such as connectors and cables, for common electronics like smartphones, electric vehicles, and computer servers. Lu credits his way of leading to a balance of Eastern discipline and Western workplace confidence, which he gained while studying and working in the United States. A foundational lesson from his mother taught him to take full responsibility, avoid self pity, and quickly move past mistakes, a clear mindset he later applied to difficult engineering problems. As a leader, Lu strongly emphasizes supporting his employees by taking personal blame for business setbacks rather than shifting it downward to others. To stay relevant and avoid falling behind, he consistently challenges his team to deliver an unexpected, fresh product or advancement every three years. Under his quiet guidance, the company has expanded significantly while building long lasting relationships with clients based on deep trust. Ultimately, Lu attributes his steady motivation to a simple, genuine enjoyment of his daily work and a constant curiosity about what comes next.


Post-quantum cryptography is not the future. It is your current reality

The article explains that post-quantum cryptography is an immediate operational necessity rather than a distant concern. Major tech companies and governments are already deploying these new algorithms because waiting for a functional quantum computer introduces severe, immediate risks to digital infrastructure. Chief among these is the "Harvest Now, Decrypt Later" strategy, where adversaries actively intercept and store encrypted network traffic today with the intention of decrypting it once advanced quantum hardware becomes available. Additionally, existing digital signatures and root certificates face future retroactive forgery, threatening the core authenticity of secure software supply chains. Successfully upgrading an enterprise is rarely an issue of funding or algorithm selection; the real challenge is an absolute lack of visibility. Modern corporate networks contain countless forgotten encryption points hidden within legacy software, cloud environments, and device firmware. To address this, organizations must establish a continuous inventory, known as a Cryptography Bill of Materials, to locate and evaluate their vulnerable assets. Once an organization maps these internal elements, it can cultivate true cryptographic agility, enabling systems to swap underlying protocols smoothly without disrupting daily operations or breaking system compatibility. Rather than delaying, companies must prioritize data based on its overall longevity and methodically adapt to finalized standards, securing their systems before the available implementation runway runs out entirely.


Non-Human Identities Are Outgrowing Your Governance Model

Many companies have developed dependable systems to manage human user identities, but they are falling behind when it comes to non-human accounts. Machine identities, such as service accounts, API keys, security certificates, and automated workloads, now vastly outnumber human credentials, particularly in cloud computing environments. Because these digital entities lack individual managers, specific start dates, or standard offboarding processes, they often slip through traditional corporate tracking systems completely unnoticed. This ongoing management gap leads to significant security problems, including orphaned accounts that maintain high-level administrative access years after a project ends, static passwords that are never rotated, and old third-party integrations that leave access doors wide open to former external vendors. Additionally, neglecting these machine identities creates serious compliance exposure during regulatory audits under strict frameworks like SOC 2 or ISO 27001, which mandate clear internal accountability and regular access reviews. To fix these issues, organizations need to update their tracking strategies and treat non-human credentials with the exact same discipline applied to human staff. This approach means assigning clear owners to every automated account, mapping their actual usage patterns, setting up predictable update cycles, and deleting them automatically when software is retired. By establishing this structured oversight, security teams can successfully close dangerous operational loopholes and maintain control.
