NEW QUESTION # 11
You are running a web application in a Kubernetes cluster using a Deployment named 'web-apps. The application is vulnerable to a known CVE that can be exploited through tne web server. You need to implement a security policy to prevent pods from accessing the vulnerable web server port.
Answer:
Explanation:
Solution (Step by Step) :
1. Identity the vulnerable port:
- For this example, assume the vulnerable port is 8080.
2. Create a Securitycontext for the web server:
3. Apply the updated Deployment: bash kubectl apply -f web-app-deployment.yaml - The 'securityContext' is used to restrict the capabilities of the container. - 'drop: ["NET BIND SERVICET prevents the container from binding to ports below 1024 (including port 8080). - This policy will prevent pods from accessing the vulnerable web server port and mitigate the CVE. Important Notes: - You can adjust the 'drop' list to restrict other capabilities as needed. - You might need to redeploy the web application with a different port that is not restricted-
