      Cybersecurity for Beginners - Kevin Clark

      Chapter 1: What Is Cybersecurity?

      Cybersecurity is a hot topic these days, but how much do you really understand? Do you know why it is so important?

      We live in a digital age. We live our lives on computers and mobile devices, all our data is stored on them or in the cloud, and that data is our world. Understanding how critical security is for private information is essential these days because our data is more vulnerable now than ever. We regularly hear of data breaches and identity theft, where millions of people are affected.

      In 2017, the WannaCry ransomware affected millions of computers worldwide. A type of crypto ransomware, it encrypted files on computers using Microsoft Windows, effectively holding them hostage and demanding Bitcoin as payment to release them. Much of the damage this and many other similar attacks caused could have been avoided if we didn't use outdated computer systems and were educated on how to avoid an attack.

      Today, virtually every company is doing everything possible to protect consumer and company data from cyberattacks, but they can only do so much. Protecting your data on your own personal devices and protecting them against attack is also down to you.

      Why Cybersecurity Is So Important

      Cybersecurity is a technology that has been designed to help protect devices and networks against unauthorized access and attacks. It is critical for a country's infrastructure, from individual users to government, military, hospitals, and businesses of all sizes, because data is the cornerstone of our world. If that data is stolen or misused in any way, it can cause significant problems for everyone involved, which is why protecting it is so important.

      The CIA Triad

      THREE PRIMARY PRINCIPLES are involved in securing an organization's data: Confidentiality, Integrity, and Availability. These make up the computer security industry standard, the CIA Triad:

      HERE'S WHAT THEY ALL mean:

      Confidentiality: These principles dictate that sensitive functions and data can only be accessed by authorized parties. A prime example of this is military secrets.

      Integrity: These principles dictate that sensitive functions and data can only be altered, added, or removed by authorized persons. An example of this is when you enter the wrong information into a database; you must be the authorized person to add or change this data.

      Availability: These principles dictate that data, functions, and systems must be available on-demand, per parameters agreed upon ahead of time according to the service levels.

      Cybersecurity Specialties

      If you are thinking about going into cybersecurity as a career, there are certain specialties that you must be aware of:

      Access Control and Methodology – this is about the protection of critical system resources from being modified or used by unauthorized persons

      Application and System Development Security – this is about database security models and how multilevel security is implemented for in-house systems and applications

      Computer Operations Security – this is about everything that goes on while a computer is operating

      Cryptography – this is about understanding what encryption is and how and when it should be used

      Law, Investigation, and Ethics – this is about the legal issues that surround computer/system security

      Physical Security – this is about how to protect physical access to workstations, servers, and devices

      Security Architecture/Models – this is all about having the right procedures and policies in place and deals with virtually every security issue an organization could face

      Security Management Practices – this is about dealing with natural disasters, catastrophic failure, and any other type of disruption effectively and efficiently

      Telecommunications and Network Security – this is about network services, telecommunications, and protocols and any vulnerabilities associated with them

      While this guide will cover a little of what a cybersecurity expert might do, it is more about what you can do to protect your own data on your own devices.

      Basic Terminology

      These are the main terminologies you need to be familiar with:

      Bots – these are computer programs that take control of your computer without you knowing. Bots can send emails, change your computer settings and retrieve web pages.

      DHCP – short for Dynamic Host Configuration Protocol, DHCP assigns every device that connects to the internet with an IP address.

      Domain Name Server (DNS) – the DNS saves every IP address and the link names. For example, if you visit Amazon.com from your browser, the name is sent to the DNS server, which then locates the IP address and sends it back to your
