Human Body and Server
By: Blessen Cherian
In this article I would like to describe how care for a human body is similar to a server. It is a globally accepted fact that everything is interrelated to each other in this world in one way or the other. Let me try to prove it in the case of a human body and a human built server.
0.1 Introduction
In this article I would like to describe how a human body is similar to a server. It is a globally accepted fact that everything is interrelated to each other in this world in one way or another. Let me try to prove it in the case of a human body and a human built server.
0.2 How is a Human Body Similar to a Server?
Being hacked is similar to getting affected by some diseases. Let us take the example of a human body being affected by some viral fever.
Why/when do you get affected by a viral fever?
It happens mainly when:
- Body loses its immunity to fight Germs
- Through unhealthy Surroundings
This is the same in the case of the servers. A server gets Hacked due to similar reasons like:-
- Lack of security measures
- Interacting with already Hacked Servers
0.3 Whats Human Health and Server health?
An individual is said to be healthy when he is free from diseases. A server is said to be healthy when its safe from hackers and provide optimum performance.
0.4 Whats Human Immunity and Server Immunity?
Human Immunity is the ability of the body to fight Germs and keep the body healthy. Server Immunity is the ability of the Server to fight against hackers and keep the servers safe and secured.
0.5 How do we increase the immunity of the Human body and Server ?
To increase the Human Body Immunity, the person or the individual should keep his body healthy by :
- Consuming good foods
- Taking care of his body by planned exercises/workouts.
- Without straining his body much.
- Conducting regular Body checkup with the advice of a good Doctor
When it comes to Server Immunity, we should follow the given below options to keep them healthy.
- Do not overload server.
- Implement server security measures.
- Install only secured software.
- Conducting regular server audits by security experts.

LinuxSecurity.com Feature Extras:
EnGarde Secure Community 3.0.4 Released - Guardian Digital is happy to announce the release of EnGarde Secure Community 3.0.4 (Version 3.0, Release 4). This release includes several bug fixes and feature enhancements to the Guardian Digital WebTool and the SELinux policy, and several new packages available for installation.
Linux File & Directory Permissions Mistakes - One common mistake Linux administrators make is having file and directory permissions that are far too liberal and allow access beyond that which is needed forproper system operations. A full explanation of unix file permissions is beyond the scope of this article, so I'll assume you are familiar with the usage of such tools as chmod, chown, and chgrp. If you'd like a refresher, one is available right here on linuxsecurity.com.
Introduction: Buffer Overflow Vulnerabilities - Buffer overflows are a leading type of security vulnerability. This paper explains what a buffer overflow is, how it can be exploited, and what countermeasures can be taken to prevent the use of buffer overflow vulnerabilities.
