AWS Penetration Testing
AWS is the largest cloud infrastructure company in the world. At the end of 2018, Amazon Web Services accounted for about 32% of the global cloud market. This popularity of the service makes AWS penetration testing so important, the relevance of which is difficult to overestimate.
What Is AWS Security?
AWS security really matters nowadays since more and more companies are choosing cloud infrastructure, some for reasons of optimization of costs for maintenance and personnel, others believe that the cloud is better protected from attacks and secure by default. Indeed, large cloud providers, for instance, such as Amazon Web Services (AWS) can afford to maintain a staff of cyber security professionals, conduct their own research, regular cloud penetration testing, and constantly improve the level of technology.

Experts believe that the multi-cloud model is the most promising way to use cloud services in the business. As the largest cloud infrastructure company in the world, AWS offers over 165 fully-featured services for all your needs. On the platform, you can create your own infrastructure from scratch or use ready-made solutions and reduce IT costs.
The platform provides mobile, web, and business applications, data processing and storage, backup, and other workloads. AWS is launching new regions faster than other vendors and is the world's most requested hyperscaler. Large companies like Netflix, LinkedIn, and Facebook choose AWS solutions.
As an AWS client, you will enjoy all the benefits of the data hub and net architecture designed for safety-conscious companies. AWS security follows the same principles as your own datacenter, with the difference that you do not need to pay for maintenance of premises and equipment. When working in the cloud, there is no need to control physical servers or storage devices.
As an alternative, you can use security tools to control and defend the inbound and outbound data streams of cloud resources. One of the benefits of the AWS Cloud is your capability to scale and bring innovations at the time you maintain a highly secure environment and pay only for the services you use. This means that the required level of security can be achieved at a lower cost than in an on-premises environment.
The AWS Cloud enables the shared responsibility model. While AWS manages cloud security, cloud security is your responsibility. This means that you are to determine which level of security you need to protect your own content, platform, applications, systems, and networks in the cloud.
However, while cloud security is a top priority for AWS, it will not protect against trivial administration errors, incorrect or default configuration settings for cloud services leaked access keys and credentials, as well as vulnerable applications. So how can you identify potential misconfigurations in an Amazon Web Services (AWS) infrastructure in a timely manner?
How AWS Penetration Testing Works?
Many IT practices have emerged as adaptations of approaches that date back to the industrial era. For example, safe makers hired bugbears to find weaknesses in their locks, and now companies are turning to hackers to identify vulnerabilities in their corporate networks. This is how a whole area appeared - ethical hacking, when penetration testing is performed by third-party specialists.
White hackers are conducting a series of cloud penetration testing, simulating various attacks. The result is a report containing detailed information about the detected vulnerabilities and recommendations for their elimination.
Specifically, AWS penetration testing most often reveals such AWS weaknesses that allow attackers to gain access to confidential data:
- AWS S3 Buckets - Open S3 Buckets configuration errors. Amazon Simple Storage Service (S3) is a service that allows you to store and receive data of any size, at any time, from anywhere in the network. Safe by default until the administrator has enabled public access.
- AWS S3 Buckets Objects configuration errors. Objects that are stored in S3 buckets can also be made public, even if the bucket itself is closed. To do this, it is enough to know the S3 URL and the names of the attached objects. S3 addresses can often be found in the source code of applications.
- XSS attacks
- Beef Hooks
- s3- [region].amazonaws.com / [target-name]
AWS Security Best Practices
Measures that include confidentiality, integrity, and availability should be taken to minimize cloud security issues. And AWS security testing should be seen as a key mechanism used during the secure infrastructure building phase. General safety guidelines are as follows:
Advice 1: Cloud applications should ensure data security and privacy in a cost-effective manner. Security in the cloud is not limited to application components and includes security at the network and data level. In addition, don't forget about regular backups and emergency recovery options.
Advice 2: Consideration should be given to configuring security policies and applying global best practices in this area. Discover all your assets using ImmuniWeb Discovery. Successful audit allows you to verify the security of the provider's cloud infrastructure.
Advice 3: Interoperability between individual infrastructure components should be maintained to potentially reduce manual testing tasks, minimize overhead and save time.
- Never use Root account keys;
- Use multi-factor authentication (MFA) for Web Console and AWS Access keys;
- Strong passwords or passphrases where MFA is impossible;
- Auditing and monitoring IAM access using AWS IAM Access Analyzer or Security Monkey;
- IAM Roles (short-term temporary credentials) instead of IAM Users;
- Git-hooks for monitoring and automatically blocking secrets leaks;
- Use regular rotation of AWS IAM Users Access keys, where it is impossible to use IAM Roles;
- Zero trust and the principle of least privileged access;
- Strong Application Security and regular Penetration Testing.
To minimize security issues in the cloud, adhere to the AWS penetration testing model, which includes identifying weaknesses in the infrastructure by performing continuous penetration testing.
