Security Groups

What are AWS Security Groups?

🔒 AWS Security Groups are like bouncers for your servers. They control who gets in and who gets kicked out. Think of them as your own personal security team, ready to protect your instances from bad actors. With Security Groups, you can create rules to allow traffic from specific IP addresses or block traffic from certain ports. They're easy to set up and can give you peace of mind knowing your instances are secure. 🔒

🏆 Security Group Best Practices 🏆

• Create separate Security Groups for different types of instances.

• The principle of least privilege refers to the practice of limiting access rights to only what is necessary for a user or system to perform their job or function. When creating rules, it is important to follow this principle in order to minimise the risk of unauthorised access or misuse of resources.

• Regularly review and update your Security Group rules.

• Use Security Group logs to monitor and troubleshoot issues.
