This is why I’ve made it a goal to help people with the resources I have. Learning tech skills in Nigeria is very hard. A lot is against you. I just hope things get better…

Cloud security isn’t just about watching tutorials or passing certs. It’s about building projects that solve real-life problems. Any Dick and Harry can talk, only few can actually do the work. I’m starting 100 days of cloud security projects. Let’s do one project every week.

Q10: You deployed a VPC with private subnets, but instances inside can’t access the internet. Why?. A: Private subnets require a NAT gateway or NAT instance to access the internet. I’d check if the route table has a route to the NAT gateway and if the NAT itself has.

Q9: You’re getting “AccessDenied” when trying to assume a role from a trusted account. What’s wrong?. A: I’d verify two things: . 1. The trust policy of the role allows the calling account. 2. I will check the IAM user/role trying to assume the role has the sts:AssumeRole.

Q8: Your AWS Config rules are not detecting misconfigurations. What could be causing this?. A: It is either Config isn’t enabled in the region, or the rule is not properly .scoped to the resource type. I’d also check if the triggering events (e.g configuration changes) are.

Q7: You enabled MFA on an IAM user, but they can still log in without it. What did you miss?. A: Here is the thing, just enabling MFA isn’t enough. I’d need to enforce it with an IAM policy condition like "aws:MultiFactorAuthPresent": "true" on sensitive actions or during.

Q6: You suddenly see your S3 bill spike, but you didn’t make any changes. What do you do?. A: I’d open the Cost Explorer to find which bucket or request type is causing the spike. I’d look for unexpected PUTs/GETs, large data transfers, or services writing logs without.

Q5: Your ALB is routing most traffic to only one target, even though others are healthy. What’s going on?. A: I think sticky sessions could be enabled, which cause traffic to stick to one target. I’d also check if cross-zone load balancing is disabled or if the load balancer is.

Q4: You deployed a new app to EKS, but the pods are stuck in “Pending.” What could be wrong?. A: The subnet might be out of IPs, or there aren’t enough nodes available. I’d also check if there’s a taint that’s preventing scheduling or if the node selector doesn’t match any.
