AWS Penetration Testing: A Comprehensive Guide

Today’s business relies on applications and data analytics. The more business processes an organization can shift toward digital systems, the more data they have to work with.Enterprise cloud platforms power these applications, and Amazon Web Services (AWS) is among the most popular.

As of 2023, Amazon claims millions of customers use AWS (AWS, 2023). While AWS offers each organization a powerful, cost-effective platform, it also raises security concerns. The old cybersecurity methods, such as firewalls and VPNs (Virtual Private Networks), do not protect a cloud platform. Securing sensitive corporate data and custom apps on AWS requires a modern approach: AWS penetration testing. Here is a guide to AWS pentesting and the tools to do it effectively.

A Deep Dive into AWS Penetration Testing

AWS penetration testing, much like other forms of pentesting, involves planned and controlled attempts to exploit weaknesses within a platform or system. Many organizations perform penetration testing and ethical hacking exercises on their systems; it’s an effective practice for finding vulnerabilities before hackers do. Pentesting in the cloud, however, is more complex.

Where AWS pentesting differs from traditional pentesting is its interaction with Amazon’s shared responsibility model. AWS penetration testers must evaluate potential security risks to determine whether Amazon or the customer is ultimately responsible. Since penetration testing activities can resemble a malicious attack, many standard pentesting practices aren’t allowed on the AWS platform.

The good news is that Amazon does encourage security testing and allows a fair number of AWS security testing techniques. Therefore, most tests fall under one of two categories:

• Cloud-native attacks: AWS security testing works with the cloud platform’s native features. For instance, you can test exploiting IAM (Identity and Access Management) misconfigurations and AWS Lambda function misses or target serverless applications.
• Misconfigured resources: Amazon S3 Buckets, EC2 Instances, KMS (Key Management Services), and AWS Config are all helpful resources on the AWS platform. However, misconfigurations can create security holes. Configurations should be pen-tested regularly.

Can We Perform Penetration Testing on AWS?

Considering the challenges of the cloud and the limitations Amazon imposes, you may wonder if you can perform penetration testing on AWS. Yes, you can. However, you must look at it differently than traditional pentesting. Allowed AWS pentesting practices include:

• Vulnerability scanning
• Web application scanning
• Port scanning
• Injections
• Exploiting found vulnerabilities
• Forgery
• Fuzzing

However, you cannot use the following pentesting techniques:

• DNS (Domain Name System) zone hijacking
• Denial of service (DoS) or distributed denial of service (DDoS) attacks
• Simulated DoS and DDoS attacks
• Port flooding
• Protocol flooding
• API request flooding
• Login/authentication request flooding

AWS penetration testing techniques that rely on brute force (or other methods resembling a DoS or DDoS attack) are generally not allowed. Before attempting any AWS security testing, ensure that it falls under Amazon’s terms of service.

Regardless of any limitations or difficulties associated with AWS security testing, it’s still an essential practice for all organizations that use the platform. Any security breach can have severe consequences, including millions of dollars in loss per incident. AWS pentesting is one of the most critical cybersecurity defenses available, given the risks involved.

AWS pentesting helps uncover the security flaws that go unnoticed — until a malicious actor exploits them. Most businesses today have legal or regulatory requirements to follow, including securing employee and customer data. Penetration testing helps safeguard this sensitive information while providing proof of compliance with laws and regulations.

Conducting Penetration Testing on AWS: Steps and Prerequisites

Before getting started with AWS pentesting, you should complete a few prerequisites.

Understand Amazon’s shared responsibility model: Read and learn the shared

responsibility guidelines. In short, Amazon’s responsibility is to secure the infrastructure that powers AWS services. Customers are responsible for the security of guest operating systems installed in their AWS clouds.

Secure your AWS environment: Apply any outstanding security updates to Linux or Windows virtual machines hosted on AWS, along with the underlying apps. Configure the AWS firewall properly and apply other AWS security functions typical to a live production environment.

Develop a plan: List the AWS instances and applications you plan to pen test. Then, note the services exposed to the public internet and develop a testing plan that adequately tests the service’s or app’s security.

After completing AWS penetration testing prerequisites, the next steps are comparable to

traditional pentesting methods:

• Get authorization: Before conducting penetration tests, acquire appropriate approval from the AWS account owner and, if applicable, the application administrator.
• Define your goals: Identify the target system and AWS service to be tested. Define the results you expect and what anomalies may look like.
• Map the attack surface: Identify the AWS services, instances, network subnets, S3buckets, IAM roles, and other pertinent services to test.
• Perform the vulnerability assessment: Use the AWS pentesting tools and search for vulnerabilities.
• Exploit the vulnerabilities: If you find a vulnerability, try to exploit it. Then, log your results.
• Report your findings: Draft a report on what your AWS penetration testing session found, along with any remediation recommendations.

Traditional Penetration Testing vs. AWS Penetration Testing

While the overall goals and general methodology of AWS pentesting may resemble

traditional methods, there are some differences to consider.

Traditional penetration testing

Traditional penetration testing often targets physical infrastructure, typically on-premises servers and networks. In that regard, traditional pentesting is often easier to plan and execute because an organization’s IT team fully owns the systems and networks to be tested.

Obtaining permission to pen test is easily accomplished, and all system administrators are aware of the penetration testing activities. Since the tester either works for the same IT team or has been granted access, they’re free to perform tests a cloud provider wouldn’t sign off on.

AWS penetration testing

In contrast, AWS pentesting focuses on cloud services, containers, serverless applications,and other cloud technologies. AWS penetration testing also has key advantages, including its suitability for automation and scaling. AWS environments feature many opportunities for automation, and pentesting is no exception. Traditional penetration testing is usually a manual process with little chance for automation. In addition, the scalable nature of the cloud makes pentesting a large platform much easier on AWS than on traditional infrastructure.

What Are the Tools Used in AWS Testing?

The limitations of AWS pentesting mean you won’t be able to use many of the common tools of the trade. However, Amazon provides many apps that function as AWS pentesting tools. These include:

AWS Command Line Interface (CLI)

The AWS CLI is a standard tool for all customers. It allows testers to interact with AWS services programmatically. You can use CLI for various tasks, including resource enumeration, security group analysis, and credential management (AWS, 2023).

AWS Identity and Access Management (IAM) Policy Simulator

The IAM Policy Simulator is another built-in AWS tool that helps testers simulate IAM policy changes and evaluate their impact on AWS resources (AWS, 2023). It’s a valuable tool for understanding the potential consequences of policy modifications.

AWS Config

AWS Config provides a detailed inventory of AWS resources and their configurations. It helps testers assess the security posture of AWS resources by identifying deviations from desired configurations.

AWS Security Hub

The AWS Security Hub has a centralized view of security alerts and compliance status across AWS accounts. It aggregates findings from various AWS security services and thirdparty tools, making identifying and prioritizing security issues easier (AWS, 2023).

AWS GuardDuty

GuardDuty is a paid add-on for AWS that provides managed threat detection services (AWS, 2023). It continuously monitors AWS accounts for malicious activity and unauthorized access, generating alerts based on AWS CloudTrail logs and VPC (Virtual Private Cloud) Flow Logs analysis.

Black-Box, Gray Box, and White-Box Penetration Testing: Importance and Uses

Penetration testing is a cybersecurity best practice that involves working with an organization to probe its IT environment for vulnerabilities. By discovering these weaknesses in advance, penetration testers hope to resolve or mitigate them before they can be exploited during a real cyberattack.

Penetration testing is pivotal in helping organizations detect IT security vulnerabilities and harden their defenses against potential cyber threats. Understanding the differences between black box, grey box, and white box testing is essential for any would-be pen tester. So, what is black box, grey box, and white box testing in cybersecurity, and what are the use cases of each type?

What Are Black, Gray, and White-Box Testing?

Black-box, gray-box, and white-box testing can be distinguished as follows:

• Black-box penetration testing (close-box penetration testing) is perhaps the most challenging and realistic form of penetration testing. As the name suggests, black-box penetration testing involves assessing the security of an IT environment or system without any prior knowledge of its inner workings.
• White-box penetration testing (open-box penetration testing) is the opposite of black-box penetration testing. During a white-box test, pentesters have full knowledge of and visibility into the target IT environment.
• Grey-box penetration testing sits somewhere between black-box and white-box testing. In a grey-box pentest, the testers may have limited or partial knowledge of the target of their attacks. Depending on the type of test, grey-box pentesters may know a little about the entire system or a lot about only part of the system.

Advantages and Disadvantages of These Testing Methodologies

Black-Box Testing: Pros and Cons

The benefits of black-box penetration testing are:

◉ Greater realism: In most cases, the perpetrators of a cyberattack are external to an organization and have little to no insider knowledge about the target’s IT ecosystem. This makes black-box testing a more realistic assessment of the organization’s security posture.

◉ Comprehensive evaluation: Black-box penetration testers often perform reconnaissance to comprehensively evaluate the target’s defenses. This can help widen the scope of the penetration test and identify weaknesses that may otherwise have gone undiscovered.

However, black-box penetration testing also comes with concerns and limitations:

◉ Lack of internal visibility: Black-box testers face the initial challenge of breaching the target’s external defenses. If the IT environment’s perimeter is secure, testers will be unable to discover any vulnerabilities within internal services.

◉ Difficulty replicating: Penetration testing can take many forms, from simple automated vulnerability scanning to highly complex attacks. Black-box testers may struggle to replicate advanced attack scenarios due to limited knowledge about the environment

White-Box Testing: Pros and Cons

The benefits of white-box penetration testing are:

◉ Full knowledge of the system: White-box testers can perform a more comprehensive security assessment than black-box testers, who may still lack crucial information after launching the attack.

◉ Static code analysis: White-box testers usually have access to programs’ source code and can perform static code analysis, unlike black-box testing (Dewhurst, 2023). This involves debugging software by scanning the code for vulnerabilities without running the application itself.

◉ Insider threat scenarios: An insider threat is an individual internal to an organization who causes harm to that organization as a result of their privileged access to IT resources (CISA, 2023). White-box pentesters can more realistically simulate insider threat scenarios.

White-box penetration testing also comes with certain downsides, such as:

◉ Too much information: White-box testers have access to massive amounts of data about an IT environment, which can itself be a disadvantage. Testers need to effectively sift through all this information and efficiently identify potential targets for attack, which means that white-box penetration testing can be more time-consuming.

◉ Greater expertise: The comprehensive evaluation performed by white-box pentesters means that white-box teams need a wider range of IT expertise. White-box penetration tests may cover everything from network architecture to program source code, so testers must understand various security vulnerabilities.

Gray-Box Testing: Pros and Cons

The benefits of a gray-box pentest include:

◉ Partial knowledge scenarios: Grey-box penetration testing can simulate advanced persistent threat (APT) scenarios in which the attacker is highly sophisticated and operates on a longer time scale (CISA, 2023). In these types of attacks, the threat actor has collected a good deal of information about the target system—similar to a gray-box testing scenario.

◉ Striking the right balance: Grey-box penetration testing allows many organizations to strike the right balance between white-box and black-box testing. For example, a fully white-box test might not be feasible due to resource or time constraints, while a fully black-box test might yield incomplete results.

The main disadvantage of gray-box testing is that it can be too “middle-of-the-road” when compared with black-box or white-box testing. If organizations do not strike the right balance during gray-box testing, they may miss crucial insights that would have been found with a different technique.

Black-Box Vs. Gray-Box Vs. White-Box Pen Testing

Black-box, gray-box, and white-box pen testing differ in several ways, including:

◉ Knowledge level: The further along the spectrum from black to white, the more information testers have about their target. Black-box testers are least informed, with no insider secrets, while white-box testers are most informed, with full visibility into the system.

◉ Objectives: Black-box testers seek to simulate attacks from an external threat with only publicly available information. White-box testers seek to thoroughly evaluate a system’s cybersecurity using internal details and resources. Gray-box testers sit somewhere between these two extremes.

◉ Use cases: Black-box testers represent the perspective of external hackers, and white-box testers represent insider threats. Gray-box testers can represent various types of scenarios based on the type of information they have access to.

How Is Black, Gray, and White Box Testing Performed?

The differences between performing black, gray, and white-box testing are as follows:

◉ Black-box testing: In a close-box pentest, penetration testers need to collect information about the target over the course of the test. They are typically provided with only minimal information to start with, such as a web application URL or an IP address. Black-box penetration testers must then fill in the gaps in their knowledge, such as by creating diagrams of IT architecture or scanning for vulnerabilities.

◉ White-box testing: Before the white-box test begins, pentesters are supplied with all the information they request about the organization’s IT ecosystem. This may include details about application source code, system configuration and design files, network users, and more.

◉ Gray-box testing: Gray-box testers may start with limited information about the IT environment. For example, they may have a high-level sketch of the system architecture or access to a limited number of user accounts. However, they may need to collect more data to successfully infiltrate the target.

Once testers receive these preliminary details, all three penetration testing methods are highly similar. The main difference between performing black, gray, and white-box testing is that the “blacker” the box, the more information testers will need to collect themselves during the test.

How to Advance Your Career with Penetration Testing

Cybersecurity penetration testing aims to simulate an attack on a computer system or network, identifying possible vulnerabilities and security flaws so that they can be fixed before an attacker takes advantage of them.

Penetration testing involves probing IT resources—such as computers, applications, or networks—for vulnerabilities or weaknesses that attackers could exploit. During a penetration test, a team of security professionals uses various tools and techniques to simulate a real-world cyberattack (e.g., stealing confidential data or disrupting normal business operations). After the assessment, penetration testers generate a report summarizing their findings and begin fixing or mitigating the discovered vulnerabilities.

While a background in cybersecurity or ethical hacking can benefit penetration testers, it is not strictly necessary to start your pentesting career. This article explores the importance of pen testing, the crucial skills to acquire to become a pen tester, and how one can leverage these skills to fast-track their career.

6 Crucial Skills to Become a Pentester

Cybersecurity penetration testing requires knowing how to discover and exploit issues in an IT ecosystem. To find success in a penetration testing career, you should have the skills and knowledge of the following:

◉ Security tools: Penetration testers have access to dozens of helpful cybersecurity software tools, including Nmap, Wireshark, Burp Suite, Metasploit, and more. These applications help pentesters perform reconnaissance and assess and exploit security vulnerabilities.

◉ Networking: Modern IT environments consist of dozens or hundreds of machines communicating via a network. Effective penetration testing, therefore, requires knowledge of computer networking hardware, software, and protocols such as TCP/IP, LAN/WAN, DNS, and more.

◉ Operating systems: Penetration testers should be proficient in common enterprise operating systems such as Windows, Linux, and macOS. This includes a comprehensive understanding of the operating system’s structure, security mechanisms, and common vulnerabilities.

◉ Computer programming: Penetration testing may require practitioners to be familiar with programming and scripting languages such as Python, Ruby, and Bash. This knowledge helps pentesters automate repetitive tasks, test exploits, and even develop their pentesting tools.

◉ Analytical and problem-solving skills: Thinking logically is valuable for many IT careers, including penetration testing. Good analytical and problem-solving skills will help pentesters find, exploit, and remediate security vulnerabilities. 

◉ Communication skills: Pentesters work closely with software developers, IT staff, and non-technical business stakeholders. This requires strong communication skills to explain complex technical issues.

Although many penetration testers have an educational background in computer science or information technology, it is not strictly necessary to have a successful penetration testing career. Other pentesters learn through on-the-job experience, while others have obtained penetration testing certifications that teach a combination of theoretical knowledge and practical skills.

Why Cybersecurity Professionals Choose Pentesting

Interest in cybersecurity penetration testing is proliferating—and is companies’ demand for qualified pentesters. Below, we’ll explore some of the reasons why so many cybersecurity professionals are choosing pentesting.

Penetration Testing Salaries

As with other subfields of IT security, knowledgeable and experienced pentesters can receive high salaries for their expertise:

◉ According to Indeed.com, the average cybersecurity penetration testing salary in the United States is over $123,000 annually (Indeed, 2023).

◉ The U.S. Bureau of Labor Statistics estimates that the median salary for information security analysts (including penetration testers) is $102,600 annually (U.S. Bureau of Labor Statistics, 2021).

Penetration Testing Career Growth

Not only is cybersecurity penetration testing a solid career in its own right, but it also leads to opportunities for career growth. After gaining experience in the field, penetration testers may qualify for other positions, such as:

◉ Senior penetration testers: Senior roles in penetration testing assume greater responsibilities, such as leading projects, developing test methodologies, and assisting more junior team members.

◉ DevSecOps roles: The DevSecOps methodology brings together software developers, cybersecurity experts, and IT operations teams, fully integrating security into the software development life cycle. Penetration testers can use their security expertise to become 

◉ IT security managers: Managerial roles oversee teams of penetration testers and other cybersecurity professionals. They also manage client relationships and develop the organization’s broader strategy for penetration testing.

◉ Chief information security officer (CISO): The CISO is an executive-level role primarily responsible for the organization’s cybersecurity. This includes managing security teams, developing security policies and procedures, and overseeing security audits and compliance efforts.

Penetration Testing Job Outlook

Cybersecurity penetration testing and other IT and software fields are expected to continue growing in the short and medium term. The U.S. Bureau of Labor Statistics predicts that between 2021 and 2031, information security analyst roles will increase at a rate of 35 percent, which is much faster than the average job. BLS also estimates that during these ten years, companies will create 56,500 new information security analyst jobs (U.S. Bureau of Labor Statistics, 2021).

The need for penetration testers and other cybersecurity professionals is mainly due to the onslaught of constantly evolving threats and malicious actors. For example, in the first quarter of 2022 alone, there were roughly 400 reported data breaches totaling more than 13 million victims (ITRC, 2022).

With businesses of all sizes and industries constantly facing new cyber threats, it is no surprise that the penetration testing market is projected to continue expanding. According to a report, the global penetration testing market will nearly double from $1.4 billion in 2022 to $2.7 billion in 2027—a healthy annual growth rate of 14 percent (MarketsandMarkets, 2022).

IoT Penetration Testing: How to Perform Pentesting on a Connected Device

The Internet of Things (IoT) is a vast, interconnected web of devices that communicate and exchange data via the internet. Any instrument that uses sensors to collect and transmit information can be an IoT device, which includes everything from smartphones and wearable technology to household appliances and industrial equipment. However, the connectivity of IoT devices also raises security concerns—and that’s where IoT penetration testing comes in.

According to a report by Palo Alto Networks, 98 percent of IoT device traffic is unencrypted, potentially exposing sensitive information to eavesdroppers. Moreover, the report finds that 57 percent of IoT devices are susceptible to medium- and high-severity exploits, making them an extremely appealing target for an attacker (Palo Alto Networks, 2020).

Despite the security risks, the number of IoT devices is soaring. Statista estimates that the number of devices connected to the Internet of Things will more than double between 2022 and 2030—from 13.1 billion to 29.4 billion (Statista, 2022).

Many IoT devices are used in homes, businesses, and critical infrastructure such as hospitals and power plants, and to help protect this massive array of devices, organizations need to perform IoT pen testing. This article will discuss the definition and purpose of IoT penetration testing, as well as how to perform pentesting on IoT devices.

What is IoT Pentesting?

Penetration testing (also called pentesting) evaluates the security of a computer system or network by simulating a cyberattack. Penetration testing aims to discover security vulnerabilities and flaws that can then be corrected or mitigated before malicious actors take advantage of them.

IoT penetration testing is the act of penetration testing for Internet of Things devices and networks. This involves the security of the IoT device itself and the communications it sends and receives (e.g., with other IoT devices and cloud computing platforms).

The techniques used in IoT pen testing include:

◉ Analyzing network traffic.

◉ Reverse-engineering the device’s firmware.

◉ Exploiting vulnerabilities in IoT web interfaces.

These methods enable IoT penetration testers to find security flaws such as weak passwords, unencrypted data, insecure firmware, and a lack of proper authentication or access control.

What is the Objective of an IoT Pen Tester?

IoT penetration testing is an essential component of a strong, comprehensive IT security program for an organization’s devices and networks. IoT pen testing aims to identify and address issues with an organization’s IoT security posture that could allow attackers to steal confidential data or gain unauthorized access to an IoT device or network. By fixing these vulnerabilities, IoT pen testers help improve the security and resilience of their systems and significantly reduce the chance of cyberattacks.

How to Approach IoT Security

IoT security is a complex and evolving field, with organizations constantly trying to stay one step ahead of their attackers. Besides IoT penetration testing, there are several ways that businesses can strengthen their IoT security:

◉ Authentication and access control: IoT devices should be protected by authentication methods such as strong passwords and multi-factor authentication. In addition, users should be granted only the permissions necessary for them.

◉ Encryption: Data transmitted between IoT devices or between the device and the cloud should be encrypted to protect against interception and tampering. If the device stores confidential or sensitive data, this information should also be encrypted at rest.

◉ Software updates: IoT device manufacturers often release updates to address security vulnerabilities and other issues. Businesses should have processes in place to regularly update IoT firmware and software.

◉ Logging and monitoring: Monitoring IoT devices for unusual activity and anomalies can help detect signs of compromise by a malicious actor. Organizations can use security analytics and threat intelligence tools to detect and respond to threats in real time.

Why is an IoT Audit Required?

IT security auditing is an important methodology for understanding and improving the effectiveness of an organization’s IT security posture. Within the broader field of IT security, businesses may have vulnerabilities in certain aspects, such as network security or application security.

With more organizations using more IoT devices, an IoT audit can help assess the security of these devices and networks. IoT audits may be required for reasons such as:

◉ Asset management: Organizations with many IoT devices can help keep track of these devices and assess their functionality with an audit.

◉ Performance management: Audits can evaluate the performance of IoT devices, ensuring that they are functioning properly and delivering the expected business value.

◉ Risk management: IoT audits can help identify unsecured devices and determine the risk of an IoT security incident.

◉ Compliance: Laws and regulations like the European Union’s GDPR and HIPAA for healthcare organizations may require companies to keep IoT data secure and private.

IoT Pentesting Methodology: How to Pentest an IoT Device

What does the IoT penetration testing process look like? The steps of IoT pen testing are as follows:

1. Planning and reconnaissance: First, penetration testers gather information about the target system or network. This may include the number and types of IoT devices, the network architecture, and any security controls in place.

2. Vulnerability scanning: Pen testers use vulnerability scanning tools to identify potential flaws in the IoT device or network, from misconfigurations to access control issues.

3. Exploitation: Once penetration testers have identified security issues, they attempt to fully exploit them possible, using them to enter and launch an attack on the network.

4. Post-exploitation: After gaining access via a particular security vulnerability, pen testers seek to extend their reach throughout the network, gathering more information or escalating their privilege. This may include installing malware or exfiltrating sensitive data.

5. Reporting and remediation: At the end of the process, IoT penetration testers produce a report detailing the vulnerabilities discovered, the extent of the attack, and the recommendations for solving or mitigating the issue.
