Secure Cloud & VPS Infrastructure Setup

Launching cloud instances without immediate hardening exposes them to automated attack bots within minutes. Khodshima Sumn Assist LTD provisions, sanitizes, and hardens AWS EC2, Hetzner,DigitalOcean, and Bare-Metal nodes with built-in zero-downtime guarantees.

Four Foundation Pillars of Cloud Security

Built from the hardware and metadata layer up to the operating system and disaster recovery:

01SSRF & Token Protection

Cloud Metadata Shield (IMDSv2)

Prevents Server-Side Request Forgery (SSRF) exploits from querying cloud provider metadata endpoints (169.254.169.254) to steal IAM role credentials and cloud API keys.

  • ✓Enforce IMDSv2 token authentication with hop-limit restrictions
  • ✓NFTables drop rules blocking web pools from querying link-local IPs
  • ✓Least-privilege cloud IAM role attachment with restricted permissions
  • ✓Automated audit alerts on metadata querying attempts
02VPC & NFTables Sync

Dual-Layer Edge & OS Firewall Sync

Synchronizes external cloud datacenter firewalls (AWS Security Groups, Hetzner Cloud Firewall, DO Firewalls) with internal operating system NFTables packet filtering.

  • ✓Stateless edge dropping before packets hit VPS virtual network interface
  • ✓Stateful internal NFTables connection tracking for authorized traffic
  • ✓Private VPC subnet peering between application nodes and database clusters
  • ✓Anti-spoofing reverse path filtering enabled on all cloud interfaces
03Clean State Baselines

OS Image Sanitization & Entropy

Standard vendor cloud images often contain outdated packages, dormant SSH hostkeys, and telemetry daemons. We sanitize the OS baseline before production launch.

  • ✓Purging vendor cloud-init telemetry and unnecessary background daemons
  • ✓Regenerating machine-id and cryptographic Ed25519 host SSH keys
  • ✓High-entropy random number generator configuration (haveged/systemd)
  • ✓Mounting /tmp and /dev/shm with strict noexec execution flags
04GPG & S3 Cold Storage

Automated Encrypted Offsite Disaster Recovery

Automated nightly backups encrypted with GPG / AES-256 before leaving the server and transmitted to external S3-compatible storage with automated retention policies.

  • ✓End-to-end client-side GPG encryption before data leaves memory
  • ✓Automated nightly database dumps and configuration state archives
  • ✓S3 bucket lifecycle rules with automated 30-day retention rotations
  • ✓Documented one-command disaster recovery restore playbook
Multi-Cloud Automation

Interactive Cloud Provisioning Blueprint

Multi-Cloud Provisioning Matrix

AWS EC2 & Lightsail Security Profile

aws_ec2_security_profile.sh
IMDSv2 & IAM Hardening
STEP 01IMDSv2 Metadata Token Lockdown

Enforces HttpTokens=required and HttpPutResponseHopLimit=1 on the EC2 instance, neutralizing SSRF vulnerabilities attempting to steal AWS IAM credentials.

Automation Command:aws ec2 modify-instance-metadata-options --http-tokens required --http-put-response-hop-limit 1
STEP 02Security Group & Internal NFTables Alignment

Locks AWS Security Group ingress strictly to Cloudflare/Reverse Proxy IPs and synchronizes with operating system stateful connection tables.

Automation Command:aws ec2 authorize-security-group-ingress --protocol tcp --port 2244 --cidr YOUR_MGMT_IP/32
STEP 03EBS Volume Encryption-at-Rest

Ensures root and data EBS volumes utilize KMS AES-256 encryption with automated snapshot lifecycle management.

Automation Command:aws ec2 enable-ebs-encryption-by-default
