The AWS VPC routing problem can be solved by checking each network element to determine where the traffic is being stopped or improperly routed. AWS VPC routing is used in AWS Virtual Private Cloud for traffic management. The incorrect routing settings in the route tables of the VPC could cause trouble in the communication of the application with its database, servers, or the internet because of the absence of routes, incorrect configuration of gateways, or incorrect association of the subnet. These factors could result in poor performance of the application, connection timeouts, and even failure of the whole system. Common reasons, 1. The application can’t reach the internet 2. The instances do not communicate with each other 3. The database …

Managing a cPanel server often involves dealing with issues that appear suddenly even when websites are still running normally. Two errors that can confuse server administrators are “Failed to receive status information from Apache” when checking Apache status and the AutoSSL message “domain.tld is unmanaged.” Although these messages are different, both can usually be investigated through cPanel & WHM, service configuration, and command-line checks. Understanding what each error means makes troubleshooting much faster and helps prevent unnecessary changes to a working server. In this guide, we will look at the possible causes of both problems and discuss practical ways to diagnose them. 1. Apache Status: “Failed to Receive Status Information from Apache” Apache is responsible for serving HTTP and HTTPS …

Cyber threats continue to evolve at an unprecedented pace, and critical Common Vulnerabilities and Exposures (CVEs) remain one of the biggest challenges for IT teams. Over the past few years, attackers have rapidly exploited newly disclosed vulnerabilities in operating systems, virtualization platforms, networking devices, VPN appliances, cloud infrastructure, and enterprise applications—often within hours of public disclosure. The biggest lesson is clear: organizations can no longer rely solely on traditional perimeter security. Infrastructure security today requires continuous visibility, rapid vulnerability management, proactive monitoring, and a well-defined incident response strategy. In this blog, we’ll explore the most important infrastructure security lessons learned from recent critical CVEs and how organizations can strengthen their cyber resilience with the right security approach. Why Critical CVEs …

Modern organizations depend heavily on servers to store information, run applications, manage databases, and support day-to-day business operations. Because so many important resources are concentrated on servers, controlling who can access them is a fundamental part of cybersecurity. Giving every employee unrestricted access can create serious security problems, while managing individual permissions for hundreds of users can become complicated and time-consuming. Role-Based Access Control (RBAC) offers a practical solution. Instead of deciding separately what every individual user can access, RBAC organizes permissions around the responsibilities of different users. People receive access according to their assigned roles, making security policies easier to manage and helping organizations prevent unnecessary access to sensitive resources. What Does RBAC Mean? Role-Based Access Control is an …

Introduction Linux powers mission-critical infrastructure across enterprises, from cloud environments and web servers to databases and application platforms. While Linux is renowned for its stability and security, it is not immune to vulnerabilities. New Common Vulnerabilities and Exposures (CVEs) are disclosed regularly, so a structured vulnerability management program is essential to protect business operations. Rather than reacting to security incidents, organizations should establish a proactive vulnerability management strategy that continuously identifies, assesses, prioritizes, and remediates risks. In this guide, we’ll explore how to build an enterprise-grade vulnerability management program for Linux servers and how SupportPRO helps organizations strengthen their infrastructure security through expert Linux server management and proactive security services. Why Vulnerability Management Matters Cyber threats continue to evolve, and …

Introduction Cybersecurity teams face a constant stream of newly published Common Vulnerabilities and Exposures (CVEs). While many CVEs receive widespread attention, not every vulnerability poses a direct threat to your environment. The real challenge is determining whether a newly disclosed CVE actually affects your servers and, if it does, how quickly you need to respond. A structured vulnerability assessment process helps organizations reduce unnecessary panic, prioritize remediation efforts, and protect critical infrastructure. This guide explains how to evaluate newly published CVEs efficiently while highlighting how SupportPRO helps businesses strengthen their security posture through proactive infrastructure management and vulnerability response. What Is a CVE? A Common Vulnerabilities and Exposures (CVE) identifier is a publicly recognized reference assigned to a known software …

Running applications on Google Kubernetes Engine (GKE) offers scalability, flexibility, and automated infrastructure management. However, operating Kubernetes clusters without proper monitoring can make it difficult to identify performance bottlenecks, resource constraints, or application failures before they affect users. An effective monitoring and alerting strategy helps teams maintain high availability by providing continuous visibility into cluster health, application performance, and infrastructure utilization. Instead of reacting to outages, organizations can detect issues early and resolve them before they become critical. This guide covers the best practices for monitoring and alerting in GKE environments to improve reliability and operational efficiency. Why Monitoring Matters in GKE GKE clusters are dynamic by design. Pods are frequently created, terminated, and rescheduled based on application demand. While …

When an Amazon EC2 instance experiences high CPU utilization, most administrators immediately assume that website traffic has increased. However, there are many situations where CPU usage reaches 80% or even 100% despite receiving very little traffic. This unexpected behavior can lead to slower application performance, increased infrastructure costs, and poor user experience. Understanding the root cause is essential before scaling your infrastructure. Why High CPU Usage Doesn’t Always Mean High Traffic CPU utilization measures how much processing power your EC2 instance is using. Although user traffic can increase CPU usage, it isn’t the only factor. Resource-intensive background jobs, inefficient application logic, operating system processes, or configuration issues can keep CPU utilization high even when only a small number of users …

When we open a website, we usually expect to see HTTPS in the browser address bar. HTTPS keeps the connection between the visitor and the website secure. It is especially important when a website handles login details, personal information, or other sensitive data. Setting up HTTPS manually can take some time. You need to get an SSL/TLS certificate, configure the web server, and remember to renew the certificate before it expires. Caddy makes this process much easier with its automatic HTTPS feature. What Is Automatic HTTPS? Automatic HTTPS is a feature in Caddy that can automatically set up HTTPS for a website. For example, suppose you have a domain called: example.com You can use a simple Caddy configuration such as: …

Introduction You check the server. CPU’s fine. RAM has headroom. Disk isn’t even close to full. And yet the site is crawling. If that sounds familiar, the problem is very likely PHP-FPM. PHP-FPM sits between your web server and your application, running the PHP code that actually generates your pages. Most people never think about it until something’s wrong, because when it’s configured correctly, it’s invisible. When it’s not, response times climb even though every dashboard you check looks perfectly healthy. Short for PHP FastCGI Process Manager, it manages a pool of worker processes. Apache or Nginx passes requests to it, those workers execute the scripts, and the output goes back out to the visitor. Get the pool sized right …
