Cyber Security Tutorials for Beginners- An Introduction

Before we move further into this cyber security tutorial, here is a brief introduction to what it is.

Cybersecurity refers to a widely accepted practice of providing protection to networks, programs and systems from all sorts of digital attacks. These could be aimed at changing, destroying or accessing sensitive data, harming business processes or even extorting ransom from users.

As we make advancements in cyber security, attackers become better, more refined and sophisticated. This is where the role of a cybersecurity professional comes into the picture. Before we step into the fields or career aspects, let's understand some common types of threats.

Types of Cyber Security Threats

Cyber threat is basically an indicating pointer towards an attempt for unauthorized access by a hacker. These can be some basic ones like an email with a clickable link. But sometimes, there are devious ones like a line of malicious code that overpasses cyberdefenses and sit idle for a long time before triggering.

Here are some of the common types of cyber threats every security employee must know about.

  1. Malware

Malware is software code written specifically with the intention to harm a system. It is a part of almost all modern cyberattacks, which are used to gain unauthorized access to systems, rendering them inoperable. Malware is also of different types including

  • Ransomware- Threatens to keep the victim's device or data locked, or publicly leak it, unless a random is paid.
  • Spyware- It's secretive malware that accumulates sensitive data like passwords, usernames, credit card numbers, etc. that is transmitted to the attacker.
  • Trojan Horse- It's a malicious code under the guise of legitimate software or a useful program. It paves way for attackers after penetrating the system.
  • Worms- These are self-replicating programs. They spread to devices and apps automatically without any human interaction.
  1. Man-in-the-Middle Attack (MITM)

This is where a malicious actor eavesdrops on a network connection to get unethical access to the messages being exchanged between two parties. It is often a result of unsecured Wi-Fi networks.

  1. Injection Attacks

Injection attacks are where malicious code is injected into a program to be able to execute remote commands. This allows attackers to change or read website data/database. Two common injection attacks are-

  • SQL Injection Attacks - The SQL syntax is exploited to expose, destroy or tamper data/ identity.
  • Cross-site Scripting (XSS) - It is quite similar to the previous one, except that it does not harm the website but those visiting it.
  1. IoT Attack

The vulnerabilities in IoT devices are used to execute IoT attacks. This is becoming more common due to increased use of industrial control systems and smart devices.

  1. Social Engineering & Phishing

Social engineering, also called human hacking, is manipulating targets so they themselves reveal confidential data. Phishing is the most pervasive type of social engineering. Fraudulent text messages, phone calls, downloadable links and emails are used to trick people. Common phishing types are

  • Whale Phishing- Super specific phishing attacks on a large scale, targeting wealthy individuals or corporate executives.
  • Spear Phishing- Specific phishing attacks on individuals by leveraging their public socal media profiles for additional authenticity.
  • Business Email Compromise (BEC)- Scammers pose as vendors, trusted business associates or executives to reach their motives. These are smart actors who do thorough research.

Applications of Cybersecurity

As this cyber security tutorial in all about data, information, and applications. Here are a few applications of cybersecurity that are the common uses of this practice.

  1. Securing Personal & Sensitive Data

Data needs to be protected, both on a personal and professional front. Even the smallest breach can lead to a huge impact on the organization's brand image. A lot of employee and client details are there, which can lead to a big ruckus if they go into the wrong hands.

This is why enterprises invest huge money to build secure systems and hire professionals.

  1. Incident Management

Indecent management facilitates responding swiftly to feasible vulnerabilities and breaches in the organization's networks. Effective control is provided on data endpoints, which helps in finding plausible infiltration and attacks. As a consequence, the credibility of an organization's assets stay put and the brand value does not get hampered.

  1. Creating Antivirus & Firewalls for Network Security

Cyber security best practices aids experts in developing different software and programs like antivirus and firewalls. These can be called shock absorbers that lower the impact of cyberattacks. Almost every organization's system built recently has the prowess to protect organizations from malicious attacks.
