How to Learn Information Security: The Best Online Infosec Training



The data that we share online, whether it’s our social security number or credit card details, is under constant threat. The need for better cybersecurity measures to combat these threats is rising. Learning information security can set you up for some of the best tech jobs available, including information security analyst. 

If you keep up with the latest computer science news, you will have heard that demand for information security professionals is growing. Businesses, banks, and government agencies are looking to hire skilled security specialists to protect the sensitive information that is crucial to their daily operations.

In this article, we will help you decide whether information security should be part of your future. To do this, we’ll go over the basics of information security, and some of the best courses on the subject.

What Is Information Security?

Information security is the process of protecting sensitive data from cyber threats and unauthorized access. This field follows three primary principles known as the CIA triad.

  • Confidentiality: This principle ensures data is protected. All data is susceptible to hacking, so organizations must shield their clients from data leaks.

  • Integrity: Data without integrity is of no use. Information security is used to ensure that data is authentic and has not been altered by an outside source. 

  • Availability: Part of keeping information secure is making sure it is available to those who need it. This means keeping systems running so that the owner of the information can access it.

What Is Information Security Used For?

Information Security is used to protect private, corporate, and user data. A variety of methods are used to make sure information is kept safe. Below are some of the most common.

Risk Assessment

Information security isn’t only for protecting data. Pre-emptive risk assessment is also a key part of security. Most companies will employ an information security analyst to scan their systems for potential threats.

The analyst will then consult with the others in the company’s IT department to seek solutions that could mitigate risks. This is an ongoing process, as technology is continually updated, which leads to new risks.

Information Security Audit 

Information security principles are also used to perform audits on a company’s infrastructure and digital servers. These audits check for vulnerabilities and compliance using penetration testing.

System Security Standards

Information security also involves testing system security standards. For example, if your company needs to add an updated software feature from a third party, it must first be assessed to make sure it meets standards.

Learn Information Security: Step-by-Step

By learning information security, you can improve your chances of getting a career in tech. You need to have a background in IT to understand the security system processes. Learning information technology is a good way to get started.

Below is a beginner’s guide to learning information security.

1. Learn Programming Languages 

Before starting your journey in information security, you must first learn the programming languages that are used to analyze system security and conduct risk assessments. You can start by learning the top programming languages in computer technology.

C, C++, Java, and Python are some of the most common languages used in information security. You can study them by enrolling in a coding bootcamp or by learning to code for free through online resources.

2. Learn the Basics of Information Security 

Now it’s time to learn the basics of information security. Take courses, watch tutorials, or read articles to find information on how information security systems work. You may also want to check out a book, such as the Beginner’s Guide to Information Security.

3. Download and Install Open-Source Information Security Systems 

Download an open-source system to practice what you have learned so far. Systems like Security Onion, KeePass, and Kali Linux are great cybersecurity software options. With them, you can apply information security principles as you practice.

4. Enroll in Advanced Information Security training

You can now enroll in advanced infosec training. Take courses that include project-based learning in cryptography, access management, and security techniques. You might want to join InfoSec Institute’s training courses to learn about cloud security, data integrity, and how to create incident response plans. Many of these classes also come with certificates of completion.

5. Join Information Security Networks 

A great way to enhance your knowledge of information security is by meeting like-minded people. Join online groups and communities to network and learn more about information security. Possible groups include the Association for Information Security Professionals (AiSP) and the Association for Executives in Healthcare Information Security (AEHIS).
