Security in Distributed Systems
In the security measures of distributed systems, such security concerns as unauthorized access, data leaks, and many others are covered. These include:
- Encryption: Scrambling data in transition and at rest with the encryption algorithms and protocols, e.g., TLS/SSL, AES, and RSA, ensures no one else other than the intended recipient can intercept or modify the data.
- Authentication: Users are given authentication processes to establish their identity by username or password, digital certificates, or OAuth.
- Access Control: Enforcing access control policies and role-based access control (RBAC) as the means of giving access only to such resources that are necessary to safe-guard sensitive data under the least-privilege principles.
- Secure Communication Protocols: Securing data exchange between distributed nodes ought to be done by using data protection protocols such as HTTPS, SSH, and VPNs, which provide confidentiality, integrity, and authenticity.
Components of Distributed System
Many modern computing platforms, such as Internet applications or systems, are built on distributed systems, which function as essential infrastructure.
- These systems feature good scalability, fault tolerances, and application flexibility, which enable them to be used in various areas, including cloud computing, IoT, and big data analytics.
- It is necessary to learn the components of distributed systems, as it would be part of designing, developing, and maintaining faultless or efficient systems.
