Cyber Security Tutorial - Learn Cyber Security from Scratch

As technology advances, cyber security hackers come up with new methods to attack and exploit people. To be safer, people must follow some security measures to prevent all these attacks. As a countermeasure, we can hack into the system and kill the attacker’s intention. This is where ethical hacking comes into the picture.

In this 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 refers to protecting our computer system, data, and network from unauthorized access.  Just think about it as we lock our doors and windows to protect our homes from unauthorized visitor

With the recent hike in cyber attacks, cyber security has become an essential skill for organisations to protect themselves from attacks. Essentially, every individual must possess some skills to counter cyber attacks and make the digital world safe.

The first worm program, written by a software programmer in 1986, shut down systems connected to the Internet. In 1994, two groups were arrested for illegally accessing 100 computers and bank accounts.

The history of Cyber security initially started as a research project when a guy named Bob Thomas designed a “Creeper” to move between the terminals of ARPANET, and a guy named Ray Tomlinson replicated a similar program called “Reaper” (identical to antivirus software) to delete Creeper.

This cyber security tutorial is designed with a similar perspective: to facilitate a large number of people, business groups, and IT organizations in helping to create awareness about hacking and the benefits of cybersecurity for organizations to prevent business losses.

Intellipaat’s Ethical hacking tutorial is a complete learning package that lists its top features and helps you learn more about ethical hacking and cybersecurity to prevent hacking and improve an organization’s security performance. This tutorial will help you learn about various techniques and tools used to penetrate the organization and protect the infrastructure ethically.

You have read in detail about cybersecurity and its fields, such as Ethical Hacking. Now, let’s take a look at some of the applications of Cyber Security used in our daily lives.

1. Securing Sensitive and Personal Data

Data has become so important in our daily lives in today’s digital world. Major industries rely on people’s data, so its security has also become so important. Minor flaws in security lead to significant consequences, which will affect an organisation’s market value and customer trust. To prevent this, an organisation must ensure strict security measures to protect people’s data.

2. Creating Firewalls and Antivirus for Network Security

Nowadays, every organisation has security measures to protect itself from cyberattacks. They are developing antivirus, firewalls, and other applications that help them to secure and remain safe from cyber attacks. As most companies are interconnected with so many systems through standard network protocols, attackers try to break the security and get into the network for further exploitation. However, these security applications and antivirus software detect anomalies and help with security.

3. Identifying Threats Through Threat Hunting

As most companies rely on automated tools for security, they also identify weaknesses by doing threat hunting, where a set of people or individuals manually check the network and system for loopholes. This helps companies improve their security if something is left undetected.

4. Incident Management

Cyber security helps an organisation report and take action during cyber attacks. Many security mechanisms work on incident management. If some anomaly is detected, it will be reported to the system, and countermeasures will be applied accordingly.

5. Application Control and System Lockdown

Hacer generally targets organisations that hold critical information, such as financial institutions and banks, and government-associated organisations that have valuable information about people. Cyber security now makes it possible to stop data breaches. If something goes wrong beyond control, it also leads to a system shutdown.
