HashCash structures exchange infrastructure security across cloud, network and server environments so core exchange services can operate within a controlled security architecture.
A crypto exchange security model cannot rely only on account authentication or wallet protection. The infrastructure beneath the platform also needs controls for network traffic, privileged access, threat detection, secrets, server exposure, monitoring and recovery. HashCash can structure these controls around the exchange's cloud and server environment, helping separate public-facing services from sensitive backend components while maintaining visibility into infrastructure activity.
HashCash can align exchange deployments with cloud-level security controls that monitor infrastructure activity, restrict access and protect backend services. For AWS-based environments, the infrastructure-security layer can incorporate appropriate AWS security and monitoring services according to the deployment.
AWS GuardDuty can support continuous threat detection and analysis of relevant AWS activity, network signals and potential security events.
AWS CloudWatch can collect metrics and logs, support alarms and provide visibility into infrastructure and application health.
AWS CloudTrail provides an activity history for actions performed by users, roles and services across the AWS environment.
AWS Macie can help discover and classify sensitive data within supported AWS environments.
AWS Security Hub can centralize security findings and related insights from supported AWS security services and tools.
Network security controls define how exchange components communicate, which resources remain private, and how external or administrative traffic can reach the infrastructure. HashCash can structure the exchange environment around network segmentation, controlled access and deployment-appropriate isolation, with the specific configuration depending on the selected infrastructure.
Capture information about IP traffic moving to and from VPC network interfaces, providing visibility for monitoring, troubleshooting and security analysis.
Control inbound and outbound traffic at the resource level, allowing access rules to be applied to EC2 instances and other supported resources.
Apply inbound and outbound traffic rules at the subnet level, providing an additional layer of network control.
Place backend services and databases in subnets without direct internet access where the deployment architecture requires it, helping separate sensitive components from public-facing resources.
Provide encrypted connectivity for authorized users or remote networks accessing private infrastructure. AWS Client VPN supports OpenVPN-based clients, while AWS Site-to-Site VPN provides private connectivity between a VPC and remote networks.
Together, these controls create defined network boundaries around the exchange, limiting unnecessary exposure while providing visibility into traffic and controlled paths for authorized access.
Infrastructure security also depends on controlling who can access cloud resources, which permissions they receive and how sensitive credentials are handled. HashCash can incorporate access and secrets-management controls into the wider exchange infrastructure security model.
Public-facing exchange services require controls that can filter unwanted traffic before it reaches application components. HashCash's wider exchange security architecture includes firewall protection and DDoS mitigation, while AWS-based deployments can use services such as AWS WAF & Shield where applicable.
Cloud security needs to continue down to the servers running exchange services. HashCash can apply server-level controls that reduce unnecessary exposure and restrict administrative access.
Configure host-level firewall rules on supported Linux environments.
Limit administrative connections and reduce exposure to unauthorized access attempts.
Disable unnecessary default accounts and manage authorized users explicitly.
Restrict remote administration to approved IP addresses where configured.
Avoid exposing unnecessary default service ports to public networks.
Infrastructure security also includes the ability to identify operational events, preserve records and recover critical systems or data. HashCash can incorporate monitoring and backup controls into the deployment according to the selected infrastructure architecture.
| Security Layer | Protection Focus | Controls |
|---|---|---|
| Cloud | Threat detection & resource visibility | GuardDuty, CloudWatch, CloudTrail, Security Hub |
| Network | Traffic control & segmentation | VPC Flow Logs, Security Groups, NACLs, Private Subnets, OpenVPN |
| Web | Application traffic protection | AWS WAF & Shield, Firewall Controls |
| Identity | Access & permissions | AWS IAM, Roles, IP Restrictions |
| Secrets | Credential protection | AWS Secrets Manager |
| Data | Data visibility & recovery | AWS Macie, Backups, Snapshots, S3 |
| Server | Host & remote-access security | UFW, iptables, SSH & User Restrictions |
Security requirements vary with the exchange architecture and the services exposed. HashCash can align infrastructure controls with the selected model rather than applying one identical configuration to every deployment.
Choosing the right infrastructure security setup requires more than selecting a cloud environment. HashCash can help align the infrastructure with the exchange's security, operational and deployment requirements.
Choose an infrastructure environment that can support the exchange's applications, databases, APIs and other supporting services.
Separate public-facing services from sensitive backend components and control how systems communicate within the environment.
Define clear user roles, permissions and administrative access paths to keep infrastructure access controlled.
Establish appropriate monitoring to identify unusual infrastructure activity and potential security events.
Maintain visibility into important infrastructure actions, configuration changes and security-related events.
Define appropriate backup, retention and recovery processes to support operational continuity.
Clearly establish who manages security configurations, updates, monitoring and incident-response activities throughout the deployment.
