** HUMAN PROPOSAL - NO BOT TEXT ** Hey, I can take full ownership of your AWS EC2 production environment immediately. It is stressful running critical workloads when your Prometheus and Grafana dashboards are not fully wired to give you real-time visibility. To secure your Ubuntu 22.04 stack, I will perform a deep audit and implement a zero-trust architecture blueprint. I will lock down your AWS Security Groups and local firewall rules to ensure only explicitly allowed traffic reaches your services. I will harden SSH access, automate your patching cycles, and configure your existing Prometheus setup to scrape metrics correctly, piping those alerts into Grafana for clear visualization and immediate notification. My goal is to transform your server from a potential liability into a predictable, robust asset. I guarantee I will support you until the entire stack is locked down, fully documented, and running perfectly. Best, Ahmad

Having worked extensively on AWS EC2 and Ubuntu 22.04 servers, I bring over 5 years of experience to the table as your go-to DevOps engineer for this project. My expertise in backend development and managing Kubernetes platforms means I understand the complex layers of server management and security you're looking for. Moreover, I am an AWS-certified professional who not only has a deep understanding of your existing technology stack but also excels in implementing cloud-based solutions. Lastly but just as crucially, I am a clear communicator who believes in thoroughly documenting my work. This ensures transparency and clarity even in highly technical aspects like setting up monitoring/alerting dashboards and notification channels or creating maintenance SOPs. You can entrust me with your production servers knowing that they will be patched, performance-tuned, and continuously protected with meticulousness that only comes from deep expertise combined with a genuine respect for the importance of the task at hand.

As a seasoned DevOps and Cloud Engineer, I understand the tremendous importance of having a robust, secure, and high-performing server infrastructure. Over my 15+ years in the field, I've delivered impactful projects across various industries – including FinTech, Media, Education, and Healthcare. My journey has honed my skills at handling CI/CD pipelines (Jenkins, GitHub Actions, GitLab CI), deploying Kubernetes and Terraform on major cloud providers like AWS/Azure/GCP, as well as securing networks with firewalls from notable brands like F5, FortiGate, Palo Alto. Moreover, I'll ensure your servers adhere to best practices in cloud security & compliance by implementing strict IAM controls, VPNs and robust Monitoring systems. Transparency is another value I hold dear. Expect an impeccable audit report containing actionable recommendations to optimize your current Linux stack (Ubuntu 22.04 on AWS EC2). Then, I'll implement agreed-upon configuration and security changes such as SSH hardening, iptables/ufw rules along with setting up automated patching and secure backups for your invaluable data. Combining my experience in server management and security with my continuous drive for self-improvement,I will deploy or refine your existing monitoring/alerting dashboards (Prometheus + Grafana) to ensure you're always aware of any potential issues. Furthermore, I'll create step-by-step maintenance SOPs to simplify future upkeep for you and your team.

Hi there, I’d love to help you take full control of your production servers. It sounds like you're looking for someone to start with a thorough audit of your existing Linux stack on AWS EC2, then move on to optimising and securing the configuration. With 4+ years of experience in system administration and security, I can ensure your machines are patched, performance-tuned, and well-protected. I’ll provide a detailed audit report and implement the necessary changes, including SSH hardening and secure backups. Additionally, I can refine your monitoring setup with Prometheus and Grafana, along with a clear maintenance schedule for ongoing support. One question I have is, do you have any specific compliance requirements or standards that need to be met for your server security? Best regards, Arslan Shahid

@maxscender

I can help you. I’ll move beyond basic OS hardening to ensure your AWS infrastructure is resilient and actually monitored, not just "installed." The immediate issue with "partially wired" Prometheus/Grafana setups is often a focus on resource metrics while ignoring security telemetry. I will configure your exporters to alert on specific anomalies—like unauthorized SSH attempts, unexpected process spikes, or unauthorized configuration changes—rather than just high CPU usage. A hidden risk in your current setup is likely the conflict between AWS Security Groups and on-server UFW rules. Redundant layers often lead to "configuration drift" where one is open and the other is closed, creating confusion during troubleshooting. I will also audit the IAM roles attached to your EC2 instances; hardening the OS is useless if the instance has over-privileged access to your AWS metadata or S3 buckets. My focus will be on: * Synchronizing AWS Security Groups with OS-level firewalls to eliminate ghost exposures. * Hardening the Linux kernel via sysctl and securing the SSH daemon. * Configuring automated, non-breaking patch management. * Building actionable Grafana dashboards that distinguish between performance issues and security incidents. * Establishing a clear "Source of Truth" for your server configuration to ensure rapid recovery if an instance is compromised.

@nemanjam61

Hello, I've worked extensively with Ubuntu server environments on AWS EC2, implementing security hardening protocols, kernel parameter tuning, and automated patching pipelines. I've configured Prometheus exporters with custom Grafana dashboards for real-time alerting on system metrics and security events. For your setup, I'd approach the audit by first mapping all running services and open ports, then benchmarking current performance before implementing CIS hardening standards. One scenario: should we prioritize fail2ban with custom rules or move toward a more comprehensive OSSEC-based intrusion detection? Let's discuss!

@Hrolgar

Production servers attract automated scanners within minutes of going live, so the gap between 'installed' and 'hardened' is the window that matters most. I'd start with lynis for a scored baseline, then close the high-priority gaps: SSH key-only with root login off, fail2ban tuned to your traffic, UFW locked to what's in use, and unattended-upgrades on security feeds only. Auditd covers the change trail. Performance side: I/O scheduler check, swappiness tuning if you're memory-bound, journald rate limits if logs are drowning out signal. I run this stack on prod Debian/Ubuntu daily. M1: Hardening baseline (SSH, fail2ban, UFW, patches), $110, 1d. M2: Monitoring and performance tuning (auditd, lynis report, I/O, swappiness), $110, 2d. What distro and version are you on?
