Information Security Tutorial and Guide

Information security is a growing concern in this very digital world. So, read on to this information security tutorial and complete guide.

In this article, we will give you a complete guide on the topic.

What is Information Security?

Information security or Infosec. It is the practice of protecting any digital and analog information or data. It covers a lot of IT domains like:

Also, it uses tools to keep unauthorized users from getting access to vital data. Thus, keeping you from harm due to information:

So, this is useful for everyone who keeps a lot of vital data. But who doesn’t today? And this is most true for companies and organizations.

In Infosec, there are three main goals most known as the CIA or:

Confidentiality. Keeps unauthorized users from getting access to data. Keeping its content safe by having restrictions. Breaches can happen due to human error, intended sharing, or malicious entry.
Integrity. Ensures that the data is real and accurate. This is by limiting consent for editing. Loss of integrity can happen for a lot of reasons. Like when analog data getting affected by environmental conditions. Or for digital data getting affected by not transferring it right. Or when users make changes that were not approved.
Availability. Ensures that authorized users can access data with ease. And they can do it safely by having steps for access. Then, having a backup to such data in case of emergencies. And keeping hardware and network connection reliable. Data becomes unavailable when events happen. Like natural disasters or device failure.

So, these three are vital. Are making sure of these? If not, you need to start now.

Of course, Infosec has many kinds. Let us get to know some of it.

This kind of Infosec protects applications and APIs. It aims to prevent, detect, and correct bugs. Or any other weaknesses in apps.

Then, application security is based on tools for:

Thus, helping find weak spots in apps. Then, once found, it gets corrected before releasing the apps. Or before any attacks happen.

Of course, the cloud needs security. Lots of us now use it more than before. So, it has extra security and tools.

Then, it focuses on weak spots from services on the internet. As well as public clouds. But this is harder to do.

Thus, cloud security needs to focus on limiting access.

This is a guide and set of tools that you follow and use when an incident happens. Thus, lessening any damage caused by:

So, the most common tool for this is the incident response plan. Or the IRP. This sets the roles all must play when responding to incidents.

This is the complete guide to Infosec. We hope you have learned a lot and see the value of Infosec. Let us keep our information safe!
