Common AWS security Threats and How to mitigate them

AWS security best practices are crucial in age once AWS dominates the cloud computing market. though moving workloads to the cloud will create them easier to deploy and manage, you’ll shoot yourself within the foot if you don’t secure cloud workloads well.

Toward that end, this article outlines common AWS configuration mistakes that might cause security vulnerabilities, then discusses strategies for addressing them.

IAM Access
The biggest threat that any AWS client can face is user access management, that in AWS-speak is thought as Identity and Access Management‎ (IAM). after you sign up for a spick-and-span AWS account, you're taken through steps that may alter you to grant privileged access to folks in your company. once the incorrect access management is given to someone that basically doesn’t need it, things will go really downhill. this is often what happened with GitLab, once their production database was partly deleted by mistake!

Mitigation

Fortunately, IAM access threats can be controlled while not too much effort. one amongst the most effective ways that to travel concerning rising IAM security is to create positive you're educated concerning however AWS IAM works and the way you'll profit of it. When making new identities and access policies for your company, grant the lowest set of privileges that everybody desires. confirm you get the policies approved by your peers and allow them to the reason why one would want a selected level of access to your AWS account. And once fully required, offer temporary access to urge the job done. Granting access to somebody doesn't simply stop with the IAM access management module. you'll profit off the VPC ways that permit directors to make isolated networks that connect with just some of your instances. This way, you'll have staging, testing, and production instances.

Loose Security group Policies
Administrators typically produce loose security group policies that expose loopholes to attackers. they are doing this because group policies are simpler than setting granular permissions on a per-user basis. Unfortunately, anyone with basic knowledge of AWS security policies will simply profit of permissive group policy settings to exploit AWS resources. They leave your AWS-hosted workloads at risk of being exploited by bots (which account for a few thirds of the visitors to websites, in line with net security company AltF9 Technology Solutions). These bots are remote-controlled scripts that run on the net searching for basic security flaws, and misconfigured security teams on AWS servers that leave unwanted ports open are one thing they give the impression of being for.

Mitigation

The easiest thanks to mitigate this issue is to possess all the ports closed at the start of your account setup. One technique of doing this is often to create positive you permit solely your IP address to attach to your servers. you'll try this whereas fitting your security teams for your instances, to permit traffic solely to your specific IP address instead of to possess it open like: 0.0.0.0/0.

Above all, ensuring you name your security cluster once operating in groups is usually an honest apply. Names that area unit confusing for groups to grasp is additionally a risk.

It’s additionally an honest plan to make individual security teams for your instances. this enables you to handle all of your instances on an individual basis throughout a threat. Separate security teams permit you to open or shut ports for every machine, while not having to rely upon alternative machines’ policies.

Protecting Your S3 knowledge
One of the largest knowledge leaks from Verizon happened not owing to a bunch of hackers making an attempt to interrupt their system, however from a straightforward misconfiguration in their AWS S3 storage bucket that contained a policy that permits anyone to browse info from the bucket. This misconfiguration affected anyplace between six million and fourteen million Verizon customers. this is often a disaster for any business. Accidental S3 knowledge exposure isn't the sole risk. A report discharged by Detectify identifies a vulnerability in AWS servers that permits hackers to spot the name of the S3 buckets. victimization this info, associate degree offender will begin reproof Amazon’s API. Done properly, attackers will then browse, write associate degreed update an S3 bucket while not the bucket owner ever noticing.

Mitigation

According to Amazon, this is often not really associate degree S3 bug. It’s merely an aspect impact of misconfiguring S3 access policies. this suggests that as long as you educate yourself concerning S3 configuration, and avoid careless exposure of S3 knowledge to the general public, you'll avoid the S3 security risks represented higher than.

Conclusion
Given AWS’s hefty market share, there's an honest likelihood that you simply can deploy workloads on AWS within the future, if you are doing not already. The configuration mistakes represented higher than which will cause AWS security problems area unit simple to create. as luck would have it, they’re additionally simple to avoid, as long as you educate yourself. None of those security vulnerabilities involve refined attacks; they center on basic AWS configuration risks, which may be avoided by following best practices for making certain that AWS knowledge and access controls are secured.
