Overview of Cyber Security
In the present world where cyber attackers are well equipped with state-of-the-art and sophisticated technologies, the risk for hacks and security breaches is at its peak. For this particular reason, security protocols need to be in place. And what is better than countering hacking with hacking itself. This is where Ethical Hacking comes to play. This highly technical job is aimed to prevent security breaches, and being government-approved, the pay is pretty high.
In this Cyber security tutorial for beginners, you will be able to get a clear idea of what is Ethical hacking, what is cyber security, System hacking types, Footprinting, Ethical hacking enumeration, Network scanning, Threats from malware, Sniffing attacks, Social engineering attacks, Session hijacking, Hacking web servers and applications, SQL injection, Wireless network hacking, Mobile platform hacking, avoiding firewall and honeypot and various Encryption techniques.

What is Cyber Security?
Cyber Security is similar to physical security or any other type of security for that matter. Physical security helps in protecting physical properties and other valuables and prevents humans from performing any accidental damage or crime on those. In the same way, Cyber Security allows organizations to protect their computer systems, end-user applications, data privacy, etc. from any form of malicious cyberattacks and other external threats.
The main aim of this technology is to avoid cybercriminals and attackers from accessing, corrupting, or making any changes to the systems, applications, and data of an organization.
Why Learn Cyber Security?
There was a huge data breach of 50 million Facebook accounts recently happened in March 2018 by a firm known as Cambridge Analytic which harvested data for US Election Predictions. The data breach came to the limelight and Facebook has levied a fine since they didn’t protect user details and due to their lack of transparency in the system. Imagine such a big firm like Facebook is susceptible to such data breaches, so Cyber security is an important measure for every organization. Cyber security is used to avoid data breaches, and protect the integrity of networks and systems from attacks.
Difference between Hacking and Ethical Hacking
|Unauthorized Intrusion into a system or network.
||Authorized method to find out the vulnerabilities of the system.
|It is illegal.
||It is legal.
|Black hat hackers perform hacking.
||White hat hackers perform ethical hacking.
|Performed by a group of people who want to steal data, and money from the organization.
||Performed by the employee of the organization to prevent real-time hacking.
The first worm program was written in 1986 by a software programmer. The worm program was used to shut down the systems which are connected to the internet. Also in 1994, two groups were arrested for illegal access of 100 computers and bank accounts.
The history of Cyber security initially started as a research project, when a guy Bob Thomas designed a “Creeper” to move between the terminals of ARPANET, and a guy Ray Tomlinson replicated a similar program named “Reaper” (similar to antivirus software) to delete Creeper.
This cyber security tutorial is designed with a similar perspective facilitating a large number of people, business groups, and IT organizations to help and create awareness about hacking and the benefits of cybersecurity for the organizations to prevent any loss in business.

Applications of Cyber Security
You have read in detail about Cyber Security and its fields like Ethical Hacking. Now, let’s take a look at some of the applications of Cyber Security used in our daily lives.
- Securing Sensitive and Personal Data
Today, data has become a significant part of our everyday lives, and its safety is the number one priority for all industries. A minor compromise in the security of an organization can have a huge impact on its brand value in the current market. This is because a lot of data stored in organizations include personal details of the clients and employees, financial details of the organization, etc., and if this data reaches the wrong hands, then it could lead to numerous business and privacy issues.
To prevent this, companies spend a large amount of money in building and learning about Cyber Security. They take measures to protect sensitive information and create better security for their future.
- Creating Firewalls and Antivirus for Network Security
Concepts of Cyber Security help professionals in developing various programs and software, such as firewalls, antivirus, and other programs, offering network security. These act as a shock-absorber that protects the company from blows like cyberattacks, and most systems today are built in a way that secures the companies from these malicious attacks.
Most financial organizations are highly dependent on computer systems to store the details of credit and debit cards, stock markets, ATM details, online banking information, and more. Often, hackers try to attack such networks using all sorts of data breaches, theft, unauthorized access, and more.
- Identifying Threats Through Threat Hunting
The process of threat hunting allows Cyber Security professionals to perform regular evaluations of the data and its environment to find any vulnerabilities and security gaps in the given system. This process helps organizations optimize their computer systems and networks and also improve the speed and accuracy of the responses.
- Incident Management
Incident management makes it possible for systems to respond quickly to feasible breaches and vulnerabilities in their networks. Cyber Security offers effective control on data endpoints to find plausible attacks and infiltration. This allows organizations to keep control of the credibility of their assets and secure their brand value in the market.
- Application Control and System Lockdown
Hackers are prone to attacking systems that are critical and have significant information that is highly valuable. Cyber Security makes sure that the systems have the highest security protocols so that they do not succumb to data theft, breaches, unauthorized access, etc.
Applications of Cyber Security also help in creating next-generation programs and software for ransomware protection, antivirus, etc. Moreover, they allow professionals to create AI-based security systems that will play a significant role in the future.
