What is the AWS Shared Responsibility Model?
The AWS Shared Responsibility Model is essentially a division of labor between AWS and its customers. AWS handles security “of” the cloud, such as infrastructure, hardware, software, and networking. Customers are responsible for security “in” the cloud, meaning they must manage data, configure rights, and control network traffic within their environment.
Can you explain what AWS secures and what the customer is responsible for?
AWS ensures the security of the infrastructure that runs AWS services, like data centers, hardware, and networking. However, customers must secure their applications, data, operating system, and network configurations they run within AWS. This means protecting endpoint devices, configuring firewalls, and ensuring data encryption.
What are some common misconceptions about AWS cloud security?
A common misconception is that AWS itself provides full security, but in reality, AWS’s availability and infrastructure are secured, not the individual customer’s applications and data. Many believe that once they migrate to AWS, they’re fully protected, but neglecting security configurations on their end can lead to vulnerabilities.
How can cloud security scanners like Intruder assist in securing AWS environments?
Cloud security scanners like Intruder help by automating the detection of vulnerabilities within your cloud environment. They continuously monitor for weaknesses, provide alerts, and recommend steps to mitigate risks. This proactive approach helps customers stay ahead of potential threats, ensuring their part of the shared responsibility model is effectively managed.
Could you provide examples of real-world vulnerabilities within AWS setups?
Certainly. An example could be misconfigured S3 buckets that inadvertently expose sensitive data to the public. Another example is overly permissive IAM roles that can give users more access than necessary. Both cases highlight how configuration errors can lead to significant security breaches.

The stack-based buffer overflow vulnerability is extremely critical as it can lead to remote code execution. This allows attackers to gain control over systems, deploy additional malicious software, and potentially steal data, compromising the overall security of the network.
Why are phishing attacks still prevalent in 2025?
Phishing attacks remain prevalent because they exploit human psychology. Attackers craft increasingly sophisticated emails and messages that appear legitimate, making it easy for even the most cautious individuals to fall for these scams. As long as human error exists, phishing will continue to be a popular attack vector.
How do phishing schemes manage to bypass various security controls?
Phishing schemes bypass security controls through techniques like social engineering, which tricks recipients into believing the messages are authentic. Attackers also use sophisticated methods to avoid detection, such as creating spoofed emails that pass through filters or employing polymorphic tactics to change the appearance of their phishing messages.
What makes Microsoft Office files particularly effective for phishing attacks?
Microsoft Office files are effective for phishing because they are commonly exchanged in business environments and generally trusted. Attackers embed malicious macros or scripts inside these documents. When an unsuspecting user opens the file and enables macros, the malware is executed, which can then compromise the user’s system.
Can you describe common phishing tactics used with Word and Excel documents?
Common tactics include embedding malicious macros in Word and Excel documents. When opened and macros are enabled, the macros execute code that downloads and installs malware. Other tactics involve embedding links within the documents that lead to malicious websites designed to steal credentials or deploy malware.
What preventive measures can organizations take to combat phishing?
Organizations should implement comprehensive security awareness training, teaching employees how to recognize phishing attempts. They should also use advanced email filtering solutions, enable multi-factor authentication, and implement strict policies on the use of macros. Regular phishing simulations can also keep employees vigilant.
What are CSRF tokens and why are they considered a best practice?
CSRF tokens are unique, unpredictable values generated by the server and embedded in web forms. They provide an additional layer of security by ensuring that requests are coming from authenticated sessions and not from malicious third-party sites. This helps to prevent unauthorized actions on behalf of the user.
Are CSRF tokens sufficient to prevent CSRF attacks? Why or why not?
CSRF tokens are effective but not infallible. While they help prevent cross-site request forgery attacks, their implementation needs to be robust. If tokens are not managed properly, such as being predictable or not rotated regularly, attackers may still find ways to exploit these vulnerabilities.
What significant threats do CSRF vulnerabilities pose?
CSRF vulnerabilities pose significant threats by allowing attackers to perform unauthorized actions on behalf of authenticated users without their knowledge. This can range from changing account settings, making transactions, or deleting data, leading to severe consequences for both users and organizations.
Can you describe the types of vulnerabilities found in solar power systems from Sungrow, Growatt, and SMA?
