How to Teach Yourself Cybersecurity

As our world becomes increasingly digital and security is ever more important, have you ever wondered how to teach yourself cybersecurity?

Cybersecurity involves protecting systems, networks, and programs from digital attacks.

Cyber attacks usually aim to access, change, or destroy sensitive information, interrupt normal business processes, or extort user money.

Teach yourself cybersecurity: understanding the basics

Before diving into how to teach yourself cybersecurity, it’s crucial to understand the basics.

Cybersecurity encompasses several sub-disciplines, including information security, network security, application security, operational security, disaster recovery, and business continuity planning.

Each area focuses on specific security aspects, but all work together to create a robust defense against cyber threats.

Information security protects information from unauthorized access, disclosure, alteration, or destruction.

On the other hand, network security is about protecting the network infrastructure from intrusions.

Application security involves securing software applications from threats from the software environment.

Operational security focuses on handling and protecting data assets.

Disaster recovery and business continuity planning include preparing for, responding to, and recovering from cyber incidents.

Teaching yourself information security

Information security is a critical aspect of cybersecurity.

To teach yourself information security, you must understand the three fundamental principles: confidentiality, integrity, and availability (CIA).

Confidentiality involves ensuring that information is accessible only to those authorized to have access.

Integrity consists of safeguarding the accuracy and completeness of data.

Availability ensures that information is available when needed.

There are several resources available online to help you teach yourself information security.

You can also read books such as “Information Security: Principles and Practice” by Mark Stamp and “Network Security: Private Communication in a Public World” by Charlie Kaufman, Radia Perlman, and Mike Speciner.

Teaching yourself network security

Network security is another crucial aspect of cybersecurity.

It involves protecting the usability, reliability, integrity, and safety of your network and data, including software and hardware technologies.

Effective network security manages access, targeting threats and preventing them from spreading on your network.

To teach yourself network security, you need to understand the different types of network security.

These include firewalls, email security, antivirus and antimalware software, and virtual private networks.

Books like “Network Security For Dummies” by Chey Cobb and “Hacking: The Art of Exploitation” by Jon Erickson can also be helpful.

Teach yourself cybersecurity: practical application

Learning about cybersecurity is not just about understanding the theory; it’s also about applying that knowledge in practical ways.

This involves using various tools and techniques to protect systems and networks from cyber threats.

These tools include antivirus software, firewalls, intrusion detection systems (IDS), and intrusion prevention systems (IPS).

Antivirus software is a program that detects and removes viruses from computers.

Firewalls are systems that prevent unauthorized access to or from a private network.

IDS are devices or applications that monitor networks for malicious activity or policy violations.

On the other hand, IPS are network security appliances that examine network traffic flows to detect and prevent vulnerability exploits.

Teaching yourself to use cybersecurity tools

There are several ways to teach yourself to use cybersecurity tools.

One way is to take online courses that provide hands-on training.

Websites like Coursera, Udemy, and Cybrary offer courses that teach you how to use various cybersecurity tools.

You can also read books like “Metasploit: The Penetration Tester’s Guide” by David Kennedy, Jim O’Gorman, Devon Kearns, and Mati Aharoni.

Another way to teach yourself to use cybersecurity tools is to set up your lab for practice.

This involves setting up a virtual environment to practice using various tools and techniques.

Websites like VulnHub and Hack The Box provide platforms to practice your skills.

Teach yourself cybersecurity: staying updated

Cybersecurity is a rapidly evolving field.

New threats and vulnerabilities are discovered daily, and new tools and techniques are developed to combat these threats.

Therefore, staying current on the latest trends and developments in cybersecurity is crucial.

There are several ways to stay updated on cybersecurity trends.

One way is to follow cybersecurity blogs and websites.

Websites like Krebs on Security, Schneier on Security, and Dark Reading provide up-to-date information on the latest threats and vulnerabilities and the latest tools and techniques to combat them.

Teaching yourself to stay updated on cybersecurity trends

If you decide to teach yourself cybersecurity, an important aspect is staying updated on trends, which involves developing a habit of reading and learning.

You can subscribe to cybersecurity newsletters, follow experts on social media, and attend cybersecurity webinars and conferences.

Websites like Cybersecurity Ventures, The Hacker News, and Infosecurity Magazine offer newsletters to which you can subscribe.

You can also follow cybersecurity experts like Brian Krebs, Bruce Schneier, and Kevin Mitnick on social media.

Attending cybersecurity webinars and conferences can help you stay updated on the latest trends.

These events are a way to share knowledge and insights and for participants to learn from each other.

Websites like BrightTALK, Cybersecurity Summit, and Black Hat provide information on upcoming webinars and conferences.

Bootcamps: a popular alternative
