Security Considerations for Distributed Systems
While data security is one of the biggest concerns in the distributed systems to prevent data theft, integrity of the communication is another crucial aspect of it. Key Security Practices include:
- Authentication and Authorization: To achieve this, one would have to make sure only the people with permission or the authorized elements are accessing the resources.
- Encryption: Applying encryption during the transmission of data such as TLS/SSL and continuing to encrypt data when at rest
- Firewalls and Network Security: Perimeter security through locking down the network boundaries and carrying out the access control.
- Intrusion Detection and Prevention: Monitoring in and addressing the threat position.
- Secure APIs: Security measure implementing that APIs use proper protection against common vulnerabilities (SQL injection, cross-site scripting) should be done.
How to build a Distributed System?
A distributed system is a system where there are separate components (nodes, servers, etc.) that are integrally linked to each other to perform the operations. These systems will be created for the capability to scale, resilience, and fault tolerance. They communicate and also collaborate their operations through networks that enable the processing, storing, and sharing of resources in a decentralized manner.
