1. Hardware Failures Disk failures: HDDs, SSDs, and RAID arrays fail from age, wear, or manufacturing defects. Power supply failures: Overloaded or faulty units take the server offline. Memory (RAM) issues: Faulty DIMMs cause crashes and unexplained reboots. GPU failures: Overheating or hardware defects in GPU-dense hosts. NIC failures: Loss of network connectivity from a […]
Storage QoS (Quality of Service) lets you guarantee I/O performance for critical workloads while preventing lower-priority traffic from starving them. The exact steps depend on your storage platform, but the workflow is consistent: identify the workloads that need guarantees, measure their actual I/O requirements, then apply policies at the storage, hypervisor, or orchestration layer. 1. […]
Public safety systems support emergency response, law enforcement, healthcare, and other essential services. A breach or outage can have severe consequences for public safety and national security. Key steps to secure your IT infrastructure: 1. Conduct Risk Assessment Identify Assets: Catalog all critical systems, including servers, storage, networking, applications, virtualization environments, Kubernetes clusters, and AI […]
Mobile devices are frequent entry points for attacks. Here are the steps to secure your infrastructure against them: 1. Develop a Mobile Device Policy Define security requirements for BYOD — personal devices used for work. Require every device, corporate or personal, to enroll in your MDM. Specify permissible apps, activities, and configurations for devices accessing […]
1. Verify the Problem Gather detailed information from users about the issue (slow connection, access denied, cannot connect). Determine whether the issue affects all users, specific applications, or certain locations/subnets. Check for specific error codes or messages displayed to users or in proxy logs. 2. Check Network Connectivity Ping the proxy server to ensure you […]
Securing IT infrastructure for healthcare systems matters because patient data is sensitive and regulations like HIPAA (U.S.), GDPR (Europe), and HITRUST carry real penalties. As the person responsible for healthcare IT, here are the strategies that work in practice: 1. Risk Assessment and Compliance Run regular risk assessments. Identify vulnerabilities, threats, and risks across the […]
