Top 15 Common AWS Mistakes and How to Avoid Them
Cloud computing has transformed how businesses operate. Amazon Web Services (AWS) is a leader in this space.
Nevertheless, many users still commit avoidable actions that would result in a loss of resources and additional costs. Here, we will highlight the top 15 common AWS issues.
We will give steps on how to avoid them.
#1: Misconfigured Security Groups and Firewalls
Issue: AWS security groups perform the function of virtual firewalls specifically for EC2 instances. A typical error is failing to restrict access to certain ports or applying loopholes in security policies that compromises resources to the internet.
Solution: Regularly assess the policies of security groups and imposition access restrictions on users in accordance with the capability of those users. Open as few ports as possible and permit access only for selected trusted IP addresses. Maintain and control your security configurations using AWS Security Hub.
#2: Not Using Multi-Factor Authentication (MFA)
Issue: Dependence on passwords only leaves room for exploitation making AWS accounts at risk of coming under unauthorized access.
Solution: Consider implementing multi-factor authentication across all accounts, particularly for the primary account. AWS also provides the option of using a hardware-based MFA key or a virtual MFA device which helps to beef up the security.
#3: Over-Provisioning EC2 Instances
Issue: It is common practice among several users to deploy bigger EC2 instances than they need, resulting in greater expenses without any proportionate performance advantages.
Solution: Utilize the smallest instance types at the beginning and increase their size by needed. AWS CloudWatch helps to determine the actual usage of the instances therefore resize the instance as needed using the actual data based on usage.
#4: Neglecting IAM Role Best Practices
Issue: Exposing your environment to these unnecessary risks can occur in instances when IAM roles that are very lax are used or the root user account is relied upon.
Solution: Formulate different IAM roles for various users and services along with a set of permissions. Always comply with the principle of least privilege – granting the user only the necessary permissions.
#5: Leaving S3 Buckets Publicly Accessible
Issue: A considerable amount of security breaches occurs because of exposed S3 buckets that are configured carelessly and left open to unwarranted access.
Solution: By default, ensure that all S3 buckets are set to private and control access using S3 bucket policies for authorized access. Utilize AWS Macie in order to keep track of and detect any sensitive information present within S3.
#6: Ignoring AWS Cost Management Tools
