The trending world is full of modern technologies and gadgets. But their security is a primary concern because; cybercrime is a global problem dominating every other technology and science. Cybercrime usually poses threats to organizations, individuals, and other institutions without providing any physical existence to the target system or organization. That is where comes the concept of security and securing the systems from such cybercriminals.
Before digging every chapter for knowledge, it is recommended to have some understanding of programming, networking, Operating Systems (OS), hardware, and software.
What is Cybersecurity?
Cybersecurity is all about reducing threats when people are in the process of dealing with technology. It encompasses the full range of protection against any online risk or vulnerability, which comprises information security assurance and cyber law enforcement. In other words, cybersecurity is the protection of cyber-space (which includes hardware, software, networks, and their servers, peripheral devices, data and information, and all other components associated with technology) and internet-connected systems from both internal as well as external threats and cybercriminals. It also comprises sub-branches that are specific to different security measures. These are:
- Network Security.
- System Security.
- Application Security.
- Information Security.
- Web Security.
- Mobile Security.
Why There Is Such a Demand for Cyber Security?
Almost everyone from this generation lives in a world of technology where the internet is connected to nearly every device around us. For cybercriminals and hackers, this is the golden age to tweak with technical stuff easily. Still, the general users are not aware of the fact that lack of security and improper use of technology can drag users and employees to doom. That is why specialized security analysts and penetration testers are hired to secure the entire system.
This subject has gradually evolved to be a new domain of learning and securing different technology such as programming, web, network, servers, applications, cloud, and many more areas.
Why Are Security Analysts in Demand?
Cyber-attacks have become a global concern as every nation is aware that cyberattacks can be stopped by the security analysts who will act as cyber armies and are trained enough to know every technical aspect of hacking and security. In this entire course, we will cover a wide range of topics right from securing systems to securing networks and personal devices, and what protocols and ports need to be taken care of to secure them will be discussed in the coming chapters.
Types of Cyberattacks
For securing any organization, system, application, network, or device, the first thing you need to know is the different ways through which cyberattacks are possible are? Here is the list of potential cyber-attacks:
- Man in the Middle.
- Password attack.
- DoS and DDoS.
- Malware and Virus-based attacks.
- Drive-by download.
- Stealing digital privacy etc.
