Bring Your Own Agent: Your Employees' Assistants Are Already Logged In
The integration of personal AI agents into the workplace is inevitable, creating
a new security challenge categorized as Bring-Your-Own-Agent (BYOA). While the
tech industry is captivated by tools like OpenClaw, Muse, Instinct, and GrokBot,
these personal assistants are quietly accessing corporate environments through
methods like OAuth consent, saved browser credentials, and API keys. Unlike the
Bring-Your-Own-Device movement where IT departments could formally register and
manage physical hardware, personal AI agents often live on vendor servers or
blend seamlessly into employee laptops, making them difficult to govern. Many
vendors are introducing controls for managed corporate deployments, but these
solutions rarely cover truly personal AI agents. Blocking them outright is
difficult and prevents employees from realizing significant productivity gains.
Instead, organizations should manage these agents by treating identity as the
central control plane. By discovering connected shadow AI, linking each agent to
a human owner, properly scoping their access, and ensuring their permissions are
revoked when the employee departs, companies can safely harness the potential of
BYOA. Security teams must adapt to this shift by prioritizing robust identity
management over attempting to ban tools that are already entrenched in their
networks.
Absence of Evidence: What an AI-Orchestrated Intrusion Harness Teaches Us About AI Detection Engineering
Recent research into SecFlow, a China-nexus AI orchestration harness, offers a critical lesson in AI detection engineering for both attackers and defenders. Developed by a Chinese-speaking operator, SecFlow used AI models like Claude, Qwen, and DeepSeek for reconnaissance, exploitation, and reporting against government and telecom targets. The harness exposed a major flaw in automated workflows: it accepted a worker’s unverified claim of a successful Apache Shiro exploit as ground truth. Because the system assumed plausible output meant actual success without checking its work, more than 27 subsequent tasks were built on this error and consequently failed. This offensive failure mirrors a significant risk for security operations centers (SOCs) relying on AI-generated detection rules. An AI tool can instantly write a rule that is syntactically correct and loads perfectly into a SIEM, giving defenders a false sense of security. However, looking correct is not the same as being operationally effective. Without executing these rules against live attacks to verify they actually fire, defenders risk deploying rules that fail silently. Ultimately, the incident underscores that in automated security engineering, plausible success must never replace proven, tested execution.A Digital Twin Is Only As Useful As The Decision It Improves
Many digital twin projects in manufacturing fail because teams focus on creating
complex, plant-wide virtual replicas instead of solving specific operational
problems. According to John Parraga, a digital twin is only truly useful when it
targets a single, high-stakes decision by modeling one process using live
operational data. The most effective digital twins are modest in scale but
deeply practical, connecting to existing systems like PLCs and historians to
validate control-sequence changes or diagnose recurring issues without gambling
an entire shift of live production. To ensure long-term success, companies must
avoid three common pitfalls that quietly erode a model's value. First, teams
must prevent scope creep by maintaining strict boundaries around the initial use
case. Second, hidden assumptions within the model should be documented clearly
so operators understand exactly what the twin is telling them. Finally, because
physical equipment and processes naturally change over time, the twin must
undergo routine recalibration to prevent model drift. Ultimately, the best
approach is to start small by testing one focused use case, proving its value in
changing outcomes, and only expanding the twin once that specific process
demonstrates measurable, repeatable success on the plant floor.AI compels organizations to rethink data security
The traditional approach to data security, relying on static firewalls and a digital perimeter, is no longer effective in the age of autonomous artificial intelligence. As these intelligent agents rapidly scan corporate networks to connect information at machine speed, they expose the hidden flaws in older security systems and magnify the risks associated with unclassified legacy data. To maintain control, organizations must adopt a highly strict mindset for these automated programs, tightly locking down their permissions just as they would for regular human employees. Because these digital workers act with inherent curiosity and constantly test the boundaries of a network, conventional identity and access systems fall short. Instead, the focus must shift directly to the data itself. By embedding access rights directly into the metadata, the information becomes self-describing and capable of acting as its own gatekeeper, regardless of the application trying to use it. Furthermore, keeping these development tools in-house rather than relying on external models ensures clear data ownership and far tighter control. Although automation introduces significant complexity and new vulnerabilities, it also provides the solution. Security teams must leverage this same processing power to continuously monitor, detect, and counter automated threats from within their own systems.Playbook for the Incoming Healthcare Regulatory Regime
Healthcare organizations must prepare for a strict new regulatory environment
that will permanently change how they manage cybersecurity. Driven by the
Health Care Cybersecurity and Resiliency Act and pending updates to the HIPAA
Security Rule, the era of treating essential security measures as optional is
finally ending. Soon, all providers will be required to implement multiple
factor authentication, encrypt protected health information, conduct regular
penetration testing, and maintain continuous network monitoring. While large
health systems may adapt smoothly, smaller clinics and rural hospitals face
significant financial hurdles. Early estimates suggest initial compliance
costs could reach nine billion dollars, yet proposed government grants offer
only a fraction of that amount with no funding guarantees. Experts strongly
advise against waiting for these regulations to become final before taking
action. Instead, organizations should begin immediately by mapping their
systems, identifying security gaps, and prioritizing vital upgrades like
authentication and data encryption. Special attention must be given to older
medical devices and outside vendor contracts, which often harbor the greatest
vulnerabilities. Ultimately, adopting these mandatory security practices is no
longer just about meeting compliance standards; it is a necessary step to
protect sensitive patient information from the growing threat of cyberattacks
and data breaches.The Non-Human Identity Blast Radius: Taming the 45:1 Machine-to-Human Imbalance
In modern digital environments, machine accounts like automated background tasks and system connections vastly outnumber human users, often by a ratio of forty-five to one. While organizations spend significant time and money managing employee access, these non-human accounts are frequently neglected. When an employee leaves a company, their access is promptly removed. However, machine accounts created for temporary projects or testing often remain active indefinitely, holding high-level permissions without any oversight. This creates a major vulnerability. Attackers specifically target these forgotten machine accounts because they bypass standard security measures like two-factor authentication. Once compromised, these accounts provide direct access to core systems while blending in with regular system traffic. To address this risk, organizations need to stop relying on permanent access keys and instead adopt systems that grant temporary credentials only when necessary. Furthermore, companies must manage machine accounts with the same strict discipline they apply to human employees. This means assigning clear human ownership to every machine account, setting expiration dates, automatically removing unused permissions, and regularly scanning for abandoned access points. Ignoring this vast portion of digital activity leaves the door wide open for security breaches, making proper, ongoing management of all automated accounts an absolute necessity today.When Should You Use Liquid Clustering? Benchmarking Lakehouse Layout Strategies
/articles/liquid-clustering-lakehouse-layout/en/smallimage/liquid-clustering-lakehouse-layout-thumbnail-1791465984987.jpg)
Choosing the best storage layout for lakehouse analytical systems isn't a
one-size-fits-all decision, and getting it wrong can negatively impact both
cost and performance. A recent benchmark comparing Liquid Clustering,
ZOrdering, and Partitioning on Delta Lake revealed crucial insights into when
to use each. While Liquid Clustering generally outperforms the others for
point lookups, time-range aggregations, and large aggregations, ZOrdering
shines when handling stable, highly selective multi-column workloads where
queries consistently filter on the same specific columns. However, ZOrdering
has a hidden flaw: if a date column is used as a secondary or tertiary key,
time-range queries can slow down significantly because sequential dates get
scattered across files. On the flip side, Liquid Clustering can be noticeably
slower than ZOrdering when queries are narrow and predictable, as its broader
optimization trades exact file pruning for flexibility. Ultimately, Liquid
Clustering is recommended as the default for teams with diverse or evolving
query patterns because it eliminates the need for manual optimization tasks.
Before making a final choice, teams should test their top query patterns
against all three layouts to see what works best for their specific data.
From IT Custodian to Business Co-Owner: How Tech Drives the Everyday Operating Model at Tim Hortons GCC
According to Vinay Kumar, Head of IT at Tim Hortons GCC, the role of technology leaders in the quick-service restaurant (QSR) industry has shifted from managing IT systems to driving business outcomes. Technology is now central to everyday operations, and CIOs must ensure their solutions are robust, agile, and easy for frontline staff to adopt. Kumar notes that a seamless customer journey requires connecting multiple backend systems—such as point-of-sale, kitchen displays, and payments—through strong integration architecture and master data management. Furthermore, system reliability during peak hours is critical, requiring a focus on offline capabilities and quick recovery rather than just system uptime. Data and artificial intelligence are also transforming operations by optimizing demand forecasting, inventory planning, and workforce management. However, Kumar cautions that AI should simplify rather than complicate the frontline experience. To achieve success, IT leaders must understand the business deeply, standardize processes, and ensure all systems provide a smooth experience for the customer, who should never have to think about the technology working behind the scenes. In this connected ecosystem, maintaining strong cybersecurity and regulatory compliance across all touchpoints is also vital.Be a good AI ancestor: Cybersecurity already gave us the playbook
In her recent article, Lisa Thee explains that the technology industry must
apply decades of cybersecurity experience to the rapidly evolving field of
artificial intelligence. While autonomous AI systems offer significant
benefits, they also introduce serious risks like unauthorized actions,
security breaches, and data exposure that require practical, technical
solutions rather than just high-level ethical guidelines. Thee argues that it
is time to move past theoretical discussions about responsible AI and instead
establish enforceable boundaries, which she calls "Red Lines." These explicit
boundaries clearly define what autonomous systems should never be allowed to
do in practice. To achieve this, organizations must empower their engineers,
cybersecurity professionals, and legal experts to design, test, and tightly
regulate AI safeguards. Just as competing companies have historically
collaborated to successfully combat digital crimes, they must now work
together across international borders to ensure AI systems operate within
safe, verifiable limits. Furthermore, businesses will soon need to provide
concrete evidence that their AI tools are secure, leading to the creation of
new specialized roles in AI safety and risk assessment. Ultimately, building a
secure infrastructure today ensures we leave behind a safe and trustworthy
digital environment for future generations to inherit and build upon safely.
Your AI agents can execute every tool call correctly and still break every enterprise rule
The article argues that even when AI agents execute every tool call correctly,
they can still violate core enterprise rules because the real risk lies not in
the tools themselves but in the decision layer that chooses how and when to
use them. It explains that most enterprise AI strategies assume a simple
formula — agents plus tools plus data equals agility — but this breaks down in
real corporate environments where compliance, governance, and financial
controls matter. Tool‑calling makes individual actions deterministic, yet the
agent’s reasoning remains probabilistic, meaning it can choose a valid tool
sequence that still bypasses labor laws, tax rules, approval workflows, or
security boundaries. Attempts to fix this from the outside, such as policy
middleware or oversized prompts, lead companies into the “shadow ERP” trap,
where they rebuild fragile copies of business logic outside their system of
record. The article argues that lawful agents require guardrails at the
inference layer: a context engine that filters what the agent can see, a
policy engine that enforces business rules, and an execution layer that
ensures actions carry the authority of the human the agent represents. The
closing message is steady and pragmatic — true enterprise‑grade AI must run
where governance already lives, because distance from the system of record
weakens both safety and speed.
