AWS Security Penetration Testing Methodology - A Complete Guide For 2024
Meaning and Significance of AWS Penetration Testing Methodology
AWS stands for Amazon Web Service. It is a platform where you can host your web services or SaaS (Software as a Service) applications. Amazon pen testing is nothing but pen testing conducted on the AWS platform. The reasons why you need to have pen testing done on AWS are:
- AWS pen testing helps you verify whether your data stored on the AWS is secure.
- Since traditional cyber security models like firewalls or VPNs do not safeguard cloud services, a novel approach like pen testing is essential.
- Amazon Web Services are used by corporates to store sensitive data which cannot be compromised at any cost.
- AWS pen testing is a legal requirement in many countries for organizations that use the platform.
- Regular pen testing is one of the basic steps to ensure compliance with specific industry standards across many industries.
Through this blog let’s explore AWS Penetration Testing in detail by analysing the types of AWS Penetration Testing, procedures involved, testing tools and techniques used, challenges associated with it and ways to mitigate them.
What Are the Challenges AWS Security Encounter?
Amazon Web Services is a cloud platform used by millions of enterprise users worldwide. As a cloud platform, traditional cybersecurity practices won’t offer much protection when you use AWS. As such, you will face several security challenges while depending on the service.
Common Security Challenges Found in The AWS Infrastructure
Low-level Data Security:
There have been many instances of people losing data stored on their AWS space as a result of hackers gaining access to their accounts. This can be a major challenge to AWS security.
Data encryption Issues:
The privacy and confidentiality of data must be protected in the AWS environment through proper encryption. Failure of this can lead to data compromises.
Difficulty in managing vulnerabilities:
When managing vulnerabilities in the AWS systems become inadequate or weak, it can affect the overall security posture and encourage hackers to exploit the vulnerabilities.
Configuration management:
Organizations that fail to configure their AWS applications properly in alignment with the best security protocols may expose themselves to more potential vulnerabilities.
Physical security flaws:
Besides the virtually existing challenges, the flaws with the physical resources part of the AWS systems can also pose a major threat to the security of the data stored in the AWS infrastructure.
Risks with supply chain and third parties:
While using AWS infrastructure with third-party services or supply chain networks, additional risks emerge from such interactions. AWS users need to identify and address such challenges before they get intensified.
Inadequate API Security:
Corporate uses AWS for the user-friendly API (Application Programming Interface) it offers. But sometimes this API can become subject to vulnerabilities exposing the users to threats.
Network security challenges:
Challenges in ensuring network security can cause an unstoppable amount of unauthorized accesses resulting in damage to the secure communication channels and leading to potential cyber threats.
Issues with Incident response and logging:
When a potential threat is reported, failure to act instantly and ensure comprehensive logging can prevent further vulnerability detection, investigations and threat mitigations.
DDoS attacks:
Distributed Denial of service attacks can negatively impact the performance of AWS services. Identifying and preventing them before they occur is essential to stop such disruption.
Challenges with compliance and regulations:
Organizations that deploy AWS resources for their services are legally required to meet specific data safety requirements along with ensuring industry-specific standards. This can become a challenging task for the organisation.
Human-related security factors:
Ignorant users, threats posed by inside actors and negligent human behaviours are factors that lead to compromise in AWS security.
Types of AWS Security Penetration Testing
There are multiple types of AWS penetration depending on the specific AWS penetration testing methodology used in the process. The common ones are:
Network Penetration Testing:
To verify whether the network structure is strong or contains vulnerabilities that a potential hacker can exploit, the pen tester simulates cyberattacks on the networks.
Web Application Penetration Testing:
In an AWS pen testing targeted at the web application, the tester performs simulated attacks on potential vulnerabilities like authentication issues or injection flaws and reports the same if a flaw is detected.
IaC Security Testing:
In this focused AWS vulnerability testing, the pen tester examines the security levels of configurations and scripts deployed across the AWS infrastructure and ensures that IaC (Infrastructure as Code) practices are in alignment with the ideal practices.
Container Security Testing:
Container security testing involves checking and identifying instances of misconfiguration and vulnerabilities associated with containerised files and their runtime and configurations
Serverless Security Testing:
Organizations may use services that do not run on dedicated servers while integrating them with the AWS environments. In this type of testing, the pen tester checks the threats on such systems that may have the tendency to penetrate to the AWS systems
Data Storage Testing:
Data storage and database security testing involves cross-checking the overall security postures, encryption types and access levels of the data storage systems used by an organization.
IAM penetration testing:
Identity and Access Management (IAM) is a protocol used by cloud services to ensure the proper access to their systems by the right users. The purpose of IAM testing is to verify whether there are any flaws with the authorization and access privileges given to the users.
Wireless Network Testing:
Wireless Network Testing focuses on evaluating the security resilience of wireless networks and various resources part of the same. The tester tries to identify any potential points in the network that a hacker might have a chance to exploit.
Incident Response Testing:
In this, the tester tries to simulate an attack that a potential hacker would do to see how the organization respond to it. Following the test, the strengths and weaknesses of the organization to respond to the incident is evaluated and reported.
Social Engineering Testing:
Most hacking attempts stem from social engineering where a hacker tries to trick ignorant users through social engineering tricks such as phishing. In this testing, such tactics are simulated by the tester to see whether employees identify them and report or fall prey to.
Identifying and Mitigating AWS Security Risks
Having understood what AWS security vulnerability is, the next important thing is understanding how to detect and resolve such risks. Let’s see how to go about that in the following paragraphs.
How To Detect Risks Associated with AWS Security?
