Introduction

"A group of distributed processes allowed to work together efficiently results in short response time, high throughput, resource sharing among the group, greater fault tolerance, and high availability. However, they do make way to challenges to such as:

1. Security (such as protection at each process and communication channel among them).
2. Maintaining data consistency across all processes."

I added some punctuation for clarity, and I adjusted the structure of the sentences to make them more concise and readable.
