NEW QUESTION # 56
Service is running on port 389 inside the system, find the process-id of the process, and stores the names of all the open-files inside the /candidate/KH77539/files.txt, and also delete the binary.

Answer:

Explanation:
root# netstat -ltnup
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 127.0.0.1:17600 0.0.0.0:* LISTEN 1293/dropbox tcp 0 0 127.0.0.1:17603 0.0.0.0:* LISTEN 1293/dropbox tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 575/sshd tcp 0 0 127.0.0.1:9393 0.0.0.0:* LISTEN 900/perl tcp 0 0 :::80 :::* LISTEN 9583/docker-proxy tcp 0 0 :::443 :::* LISTEN 9571/docker-proxy udp 0 0 0.0.0.0:68 0.0.0.0:* 8822/dhcpcd
...
root# netstat -ltnup | grep ':22'
tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 575/sshd
The ss command is the replacement of the netstat command.
Now let's see how to use the ss command to see which process is listening on port 22:
root# ss -ltnup 'sport = :22'
Netid State Recv-Q Send-Q Local Address:Port Peer Address:Port
tcp LISTEN 0 128 0.0.0.0:22 0.0.0.0:* users:("sshd",pid=575,fd=3))

NEW QUESTION # 58
You are tasked with securing a Kubernetes cluster that runs sensitive workloads. You need to implement a mechanism to enforce least privilege access for all pods in the cluster.

Answer:

Explanation:
Solution (Step by Step) :
1. Create a Service Account with Limited Permissions:
- Create a new ServiceAccount with minimal permissions:

2. Create a Role with Limited Permissions: - Create a Role that only grants the necessary permissions for the pods:

3. Bind the Role to the Service Account: - Bind the Role to the ServiceAccount:

4. Configure PodS to use the Service Account - Update your Deployment YAML to use the ServiceAccount:


NEW QUESTION # 59
You are running a Kubernetes cluster with a variety of workloads. One of your applications is a database that stores sensitive customer data- To enhance security, you need to implement network policies to limit the network traffic to and from this database pod. Specifically, you want to only allow access to the database from your application pods and deny all other traffic.
Create a NetworkPolicy that accomplishes this objective.

1. Define the NetworkPolicy:
- Create a NetworkPoIicy YAML file.
- Define the policy name and target pods.
- Specify the ingress and egress rules.
- Example:

2. Apply the NetworkPolicy: - IJse ' kubectl apply -f database-policy-yamp to apply the policy. 3. Verification: - Verity that the NetworkPolicy is applied successfully- - Use 'kubectl get networkpolicies' to list the existing policies. 4. Test the Policy: - Attempt to access the database pod from a pod outside of the 'application' label. - The access should be denied due to the NetworkPolicy.


NEW QUESTION # 60
