What is Cyber Security?

This Cyber Security is a discipline that covers how to defend devices and services against electronic attacks by malevolent actors such as hackers, spammers, etc. It is a term to describe all forms of protection against every form of cyber threat. Cyber security allows organizations to protect their computers and applications from any form of malicious attacks. This technology's main aim is to prevent cyber attackers from corrupting or accessing an organization's systems or data.  

what is cyber security

A cybersecurity tutorial is designed to help many audiences, organizations, and businesses create awareness about hacking and help them in the long run. As hackers are becoming more competent in their hacking approaches, having some protocol to protect us from the evil effects of such cyber attackers ensures that our data doesn’t get into the wrong hands. So, when discussing cyber security, you might think, “What are we trying to protect ourselves from?” Here are the three aspects-

  • Unauthorized access
  • Unauthorized deletion
  • Unauthorized modification

These are synonymous with the CIA triad, which stands for Confidentiality, Integrity, and Availability.

What are the Types of Cyber Threats?

types of cyber attack

Cyber attacks hit organizations and businesses every day. Cyber professionals are continually striving to defend these services from the risk of getting hacked. A cyber threat refers to any possible malicious attack that seeks to illegally access data, disrupt digital operations, or damage information. Reading our cyber security tutorial till the end shall give an in-depth understanding of the various types of cyber threats that should be taken care of along with cyber security best practices:

  1. Malware- It is malicious software that includes spyware, ransomware, viruses, and worms. It may install harmful software, block access to your computer resources, disturb the system, or secretly transfer information from your data storage.
  2. Trojans- Do you know the story of the Trojan Horse in mythology? Similarly, trojans in cyber security trick the attackers into thinking that they are opening a harmless file. It creates a backdoor to access data from the system.
  3. Phishing- Phishing attacks use fake communication such as emails, tempting the user into opening it and carrying out the instructions written inside. The goal is to steal sensitive information such as credit card pins or numbers.
  4. SQL Injection- SQL or Structured Query Language injection is a malicious attack on a server using SQL. The server releases information after being attacked.
  5. Denial of Service(DoS)- DoS is a type of cyber attack that floods the system or network so that it is unable to respond to requests. This is done to “handshake” processes and effectively overload the system to make it incapable of responding.

What is Ethical Hacking & How is it Different From Hacking?

The term “hacker” was initially coined to describe the experts who have used their skills to overhaul mainframe systems, increase efficiencies, and enable them to perform multiple tasks at the same time. However, the new version of hacking means gaining unauthorized access to computer systems by using bugs or malice. Further down, our cyber security guide shall expand on the term ethical hacking and how it is different from normal hacking. Learn what are the Top 10 Ethical Hacking Tools in 2024 to become a certified hacker.

Firstly, you need to understand that all hacking is not bad, which is something that is covered in the cyber security fundamentals. This is where the term “ethical hacking” comes in. Ethical hacking is an authorized practice of identifying vulnerabilities in an organization's application, system, or infrastructure and circumventing the system. The primary work of ethical hackers is to investigate the weak points or vulnerabilities that make it easier for the “unethical” hackers. Ethical hackers are hired by organizations to look into the vulnerabilities in their systems and design solutions through cyber security techniques to protect against data breaches. A good Cyber security basics training course can give greater insights into the skills and responsibilities of an ethical hacker. 

Hacking

Ethical Hacking

Steal valuable information of companies and individuals for illegal activity

Hack system to reduce vulnerabilities in the company’s system

Hack system to reduce vulnerabilities in the company’s system

Legal practice, authorized by the company or individual

Such types of hackers are called black-hat hackers

Such types of hackers are called white-hat hackers

Such hackers try to access restricted networks through illegal practices and reduce the security of data

Such hackers create firewalls and security protocols

They work for themselves for dirty money

They work with different government agencies and big tech companies

What is Penetration Testing? How is it Different from Ethical Hacking?

Till now, we have discussed ethical hacking. But how is penetration testing different from ethical hacking? Ethical hacking is a broad area and an encompassing term, while penetration testing is a part of ethical hacking. Let’s explain briefly about the difference between ethical hacking and pen testing in this cybersecurity guide.

Penetration Testing, also referred to as Pen testing, is a simulated cyber attack to check the weak points or the vulnerabilities of your computer system. It involves breaching front-end and back-end servers to uncover vulnerabilities that are prone to code attacks. Penetration testing includes 5 stages:

5 stages of Penetration Testing

Penetration testing is specifically aimed at evaluating information systems, whereas ethical hacking encompasses a wider range of activities for safeguarding these systems. Ethical hacking involves a broader array of job functions and responsibilities compared to penetration testing. With this distinction in mind, let's explore the tools and platforms commonly utilized by ethical hackers.

What is Kali Linux?

Kali Linux is a Debian-based OS specifically tailored for advanced penetration testing and security auditing. It is a popular choice among hackers and security experts alike. The platform includes a vast array of tools designed for a variety of information security tasks, including computer forensics and reverse engineering.

Key features of Kali Linux are:

  • Over 600 tools

What is SQL Injection? How to prevent SQL Injection?

After learning about ethical hacking and penetration testing you must have an idea by now that these web hacking techniques are becoming increasingly popular, particularly the ones that can potentially damage your software. Another dangerous technique is  SQL Injection that can affect data-driven applications. SQL Injection involves inserting harmful SQL code to gain unauthorized access to data, which can potentially damage or corrupt your database.

SQL Injection is mainly a code-based vulnerability that enables an attacker to access and retrieve sensitive data from a database. By exploiting this vulnerability, attackers can circumvent application security measures and execute SQL queries to alter, add, update, or delete records within the database. Websites or web applications that utilize relational databases such as MySQL, Oracle, or SQL Server are particularly susceptible to SQL injection attacks. Recent years have seen numerous security breaches attributable to such attacks.

Different types of SQL Injection

SQL INJECTION

How to Prevent SQL Injection

Here are some effective strategies to prevent SQL injection:

  • Use Prepared Statements and Parameterized Queries: These approaches ensure that parameters inserted into SQL statements are handled securely, reducing the risk of injection attacks.
  • Object-Relational Mapping (ORM): ORM frameworks help development teams convert SQL result sets into code objects smoothly, minimizing direct SQL query handling.
  • Escape Inputs: Escaping input is a straightforward method to defend against SQL injection. Many programming languages offer built-in functions for this purpose. It's important to use escape characters correctly when constructing SQL statements in your code.

Additional methods to safeguard against SQL injection include:

  • Password Hashing: Encrypting passwords to enhance security.
  • Third-Party Authentication: Utilizing external authentication services for added protection.
  • Web Application Firewall (WAF): Implementing a WAF to filter and monitor HTTP requests.
  • Upgrading Software: Investing in high-quality software with robust security features.
  • Applying Patches and Updates: Regularly updating software and applying patches to fix vulnerabilities.
  • Continuous Monitoring: Keeping an eye on SQL statements and database activities to detect and respond to suspicious actions.

What is Firewall and Why Is It Important For your Data?

By now, you should recognize the serious threat that cyberattacks pose to your system and data. Nevertheless, cybersecurity engineers have been diligently working to counter these threats with strong security measures. One such tool that can help protect your network and devices from unauthorized access is a firewall. Let’s learn about this below:

A firewall is a network security tool that monitors and controls both incoming and outgoing network traffic based on predefined security rules set by an organization. It essentially serves as a barrier between an internal network and the public Internet.

Just as a fence around a property keeps your home secure and deters intruders, firewalls protect computer networks. These security systems block unauthorized access and can be either hardware-based or software-based. They filter network traffic according to established rules to identify and prevent potential cyberattacks.

Firewalls are essential in both business and personal environments, forming a critical part of network security. While most operating systems come with a basic firewall, third-party firewall applications offer enhanced protection

Different Types of Firewalls

Firewalls come in two main forms: software and hardware. Software firewalls are applications installed on individual computers that manage network traffic by regulating applications and port numbers. In contrast, hardware firewalls are physical devices positioned between your network and the gateway. Additionally, firewalls provided as a service through the cloud are known as cloud firewalls.

Some common Types of Firewall

Firewalls can be categorized based on their methods of traffic filtering, structure, and functionality. 

Some Common types of Firewall

  1. Packet filtering
  2. Proxy Service Firewall
  3. Stateful Inspection
  4. Next-Generation Firewall (NGFW)
  5. Unified Threat Management (UTM) Firewall
  6. Threat-Focused NGFW

1. Packet Filtering

This type of firewall controls the flow of data to and from a network by allowing or blocking packets based on their source address, destination address, and the application protocols used.

2. Proxy Service Firewall

Proxy firewalls operate at the application layer, acting as an intermediary between networks. They filter messages to protect the network by serving as the gateway for specific applications.

3. Stateful Inspection

Stateful inspection firewalls manage network traffic based on the state of the connection, port numbers, and protocols. They apply filtering rules defined by administrators, considering the context of the traffic.

4. Next-Generation Firewall (NGFW)

According to Gartner, Inc., next-generation firewalls offer deep packet inspection along with application-level monitoring, intrusion prevention, and external threat intelligence. They provide more advanced capabilities beyond traditional port and protocol inspection.

5. Unified Threat Management (UTM) Firewall

UTMs combine various security functions into a single device, often integrating stateful inspection, intrusion prevention, and antivirus protection. They may also include additional features and cloud management options, designed for ease of use.

6. Threat-Focused NGFW

These firewalls are designed for advanced threat detection and response. They utilize network and endpoint event correlation to identify and address evasive or suspicious activities effectively.

This overview has provided a snapshot of cyber threats and cybersecurity measures. Next, let’s explore the career opportunities available in the field of cybersecurity and the skills required to succeed in this dynamic and rapidly evolving industry.
