Distributed Systems Security
Security is important in distributed systems because they are complicated and spread out across many computers. We need to keep sensitive data safe, make sure our messages are not tampered with, and protect against hackers. Here are the main ways we do this:
- Encryption: This means making data unreadable to anyone who shouldn’t see it. We do this when data is moving between computers or when it’s stored somewhere. It keeps sensitive information safe even if someone tries to snoop.
- Authentication: This is about making sure that the people, devices, or services trying to access the system are who they say they are. We use things like passwords, fingerprint scans, or special codes to check their identity.
- Access Control: This is like having locked doors that only certain people can open. We decide who can see or change things in the system and make sure nobody else can get in where they shouldn’t.
- Audit Logging: This means keeping a record of everything that happens in the system so we can check if something bad has happened or if someone tried to break in. It’s like having security cameras everywhere.
- DDoS Mitigation: Sometimes bad actors try to overwhelm the system with too much traffic to shut it down. We use special tools to filter out this bad traffic and keep the system running smoothly.
Distributed System Principles
Distributed systems are networks of interconnected computers that work together to solve complex problems or perform tasks, using resources and communication protocols to achieve efficiency, scalability, and fault tolerance. From understanding the fundamentals of distributed computing to navigating the challenges of scalability, fault tolerance, and consistency, this article provides a concise overview of key principles essential for building resilient and efficient distributed systems.
