How to Detect and Correct Security Drift in Your Environment

I learned something interesting today about Certificate Transparency (CT) logs and why they matter for security. CT logs don’t hand attackers code or direct vulnerabilities. What they do give is a public map of every TLS/SSL certificate issued for a domain — and that map can expose parts of a company you forgot existed. What attackers look for in CT logs • Forgotten subdomains — test.dev.example.com or old-api.example.com that were never hardened or monitored. • Service names that scream “try here” — vpn.company.com, remote.company.com, etc. Those point attackers to places worth poking for misconfigurations. • Signs of poor management — expired or poorly managed certs often correlate with neglected systems. Why this matters CT logs are reconnaissance. They help attackers find targets faster by revealing an organization’s digital footprint. Once they know where older or hidden services live, they can focus efforts on those weak spots. Defensive takeaways (short): • Track every cert issued for your domain. • Inventory and harden subdomains and services you find. • Treat CT logs as a signal to audit, not as a direct vulnerability report. CT logs turned discovery into a public, cheap tool. That’s why visibility and good hygiene matter more than ever. #CyberSecurity #CertificateTransparency #InfoSec #ThreatIntel #NetworkSecurity #SecurityOps #LearningInPublic

Most organizations think having a password policy means they’re compliant. Reality check: policy ≠ enforcement. Typical report: “Password policy exists. Users follow it.” Mine: “Assessed 200+ accounts. Found 18% using weak passwords. Recommended MFA and automated expiry alerts.” Why it matters: 1. Policies need proof, not presence 2. One weak password = full compromise 3. Actionable insights > generic statements Strong password policies only work when enforced and monitored. Hands-on assessments turn theory into resilience.

⏳ Digital Clutter Can Be a Hidden Security Risk “I’ll just share this file quickly…” We’ve all said it. And in the moment, it feels harmless. But those “temporary” shares often turn into permanent vulnerabilities. During a recent client security audit, we uncovered 300+ sensitive documents with unrestricted access—files that were meant to be shared “just for now” but had been open for 18 months. 😱 The uncomfortable truth: Every shared file without an expiration date is a potential data breach waiting to happen. For leaders, this raises an important question: 🔍 Do you have automated expiration policies for file sharing? 🛠 Or are you relying on manual “remember to revoke access” processes? 💬 I’d love to hear: What’s your process for managing temporary file shares? #Cybersecurity #DataProtection #InformationSecurity #RadiantResources #DigitalResilience #CISO #RiskManagement

Compliance ≠ security. Passing an audit is a snapshot; attackers move every day. This week’s issue is a MUST-READ if you: • Rely on annual audits to “prove” you’re safe • Want a practical plan for ongoing security • Need real data to focus Q4 efforts Inside the issue: ✅ Reality Check: Compliance ≠ Security — why passing audits isn’t guaranteed protection 🛡️ Your Audit Isn’t the End — how top teams run continuous compliance 📊 HIPAA Wall of Shame (2025 YTD) — 426 breaches, 33M+ affected; 80% hacking/IT; most incidents hit network servers and email 👉 Read the newsletter: https://lnkd.in/g_uJQrBW #Compliance #Security #HIPAA #SOC2 #ISO27001 #AIGovernance #VendorRisk #VRC1 #VanReinCompliance #NewsletterWednesday

A client once assumed their compliance reports meant they were secure. On paper, everything looked perfect, policies documented, checklists ticked, audits completed. But during a deeper review, I noticed a single oversight: critical logs weren’t being monitored in real time. That one blind spot meant if attackers slipped through, there would be no immediate trace. Detection could take weeks, enough time for data theft, system downtime, and millions in damages. By catching the issue early and redesigning the process, the company avoided what could have been a devastating financial and reputational hit. This is why cybersecurity isn’t just about policies. It’s about ensuring controls actually work in practice. Do you think compliance automatically equals security, or should businesses dig deeper? #CyberSecurityLeadership #GRCExperts #BISO #RiskManagement #BusinessAnalysis #ComplianceStrategy #WomenInCyber

Critical Security Alert! 🚨 New security flaw in ZIP files affects multiple applications. A critical vulnerability, named "Zip Slip," has been discovered, impacting numerous applications and libraries that process ZIP files. This flaw allows attackers to perform arbitrary file write attacks, which could compromise entire systems. 🔍 What does the flaw involve? The issue lies in the fact that many applications do not properly validate filenames within compressed files. An attacker can create a malicious ZIP file with manipulated paths that, when extracted, allow overwriting critical system files outside the intended destination directory. 📊 Potential impact: - Remote code execution - Overwriting of system files - Privilege escalation - Compromise of system integrity 🛡️ Mitigation recommendations: - Immediately update all affected applications and libraries - Implement strict path validations during extraction - Use security solutions that detect malicious ZIP files - Conduct security audits on systems that process compressed files This type of vulnerability affects multiple environments, from enterprise applications to development tools. Awareness and timely application of patches are crucial to prevent exploitation.

What is spillage in cybersecurity, and how can your business prevent it? Spillage happens when sensitive data is exposed to unauthorized people, systems, or environments. It can be the result of human error, system misconfigurations, or cyberattacks. For industries like healthcare, finance, and legal, the risks are real. A single data spill can lead to compliance violations, financial losses, and a damaged reputation. In our latest blog, we cover: ✔️ What spillage is and how it happens ✔️ What’s at stake if it goes unaddressed ✔️ How to prevent it through strong controls, staff training, and AI-driven tools If your organization handles sensitive data, this is essential reading.

This really hits home. It’s so easy to get swallowed by the day-to-day grind of alerts and compliance, especially when the frameworks and tools start feeling like an end in themselves rather than a means to protect what’s truly important. I agree completely that impact over process should be the north star. Automation and critical thinking not only help cut through the noise but also keep the work engaging and meaningful. At the same time, I think it’s important to remember that frameworks and tools, while sometimes overwhelming, do provide valuable guardrails—especially in complex environments or regulated industries. The challenge is striking the right balance: using them to support the mission, not replace it. Ultimately, keeping the passion alive in this domain requires both the mindset and the environment that empowers security teams to focus on what really moves the needle. Thanks for sharing these insights—they’re a great reminder to step back, refocus, and reclaim what made cybersecurity exciting in the first place. #cybersecurity #persistence #security #passion
