The retail industry, the medicine industry, the banking and finance industry, the construction industry, the transportation industry, the communications, media, and entertainment industry, the education industry, the manufacturing, and natural resources industry, the various industries related to the government, the energy and utilities industry, and the outsourcing industry all make heavy use of technology.
What we are trying to point out by showing our heavy reliance and usage of technology is that we as human beings have become completely dependent on technology, to the point that technology has started to shape our lives to a large extent.
Now let us consider a hypothetical scenario – a terrorist organization has invented a computer virus that is capable of scrambling all of our existing technological systems into an unusable and uncontrollable mess. If this terrorist organization is able to spread such a computer virus around the world, it would cause absolute chaos and mayhem in the lives of all human beings present on this planet.
This scenario is not entirely hypothetical. After all, several terrorist organizations and even several secret agencies, and other security organizations have already made several attempts to create and spread such computer viruses throughout the technology systems of the world. This opens up several opportunities for lucrative Cybersecurity Careers.
There is a well-known sabotage attempt made by the Central Intelligence Agency of the US in which they attempted to and succeeded in sabotaging the nuclear power plants of the country of Iran. Some of their covert operatives infiltrated the nuclear power plants of Iran and spread the Stuxnet virus throughout the technology systems of the nuclear power plants of Iran and completely disrupted and destroyed the technological systems on the basis of which these nuclear power plants were operating.
From these instances of sabotage and outright cyber warfare, we can easily see the need for stable and secure technological systems, the emphasis being on the keyword ‘secure’ here. Without an adequate amount of research and planning going into providing safety and security to the technological systems which are so prevalent in the modern world, there is little chance of ever achieving stability in their functioning. So the need of the hour is people with Cybersecurity skills.
This is because there will always be unscrupulous elements present in human society and they will always try to disrupt and disturb the functioning of these technological systems. They know that human society is largely dependent on these technological systems to lead peaceful and active lives and they want to disturb this state of affairs and cause agitation in human society on a large scale.
So cybersecurity is the art and science of protecting technological systems against these unscrupulous elements with the help of security best practices and specially written and specially targeted software applications. These software applications are usually called antivirus software or antimalware software. One can learn how to write such applications by getting a CISSP certification online.
They are usually very complex and sophisticated pieces of software and usually require large teams of programmers and software developers to create. They are then fed large lists of computer viruses, trojan horses, worms, and other miscellaneous malware as inputs.
With the help of these large data sets of inputs, they can easily detect any computer viruses, trojan horses, worms, and other miscellaneous malware if it is present on any computer system. In this way, software developers and computer programmers can guard technological systems against the presence of foreign elements and against attacks made by unscrupulous elements who mean to do them harm.
There are 8 main areas or fields of specialization in cybersecurity. They are discussed in CISSP training. They are -
For a beginner, the best area or field of specialization to start studying in the field of Incident Response and Forensic Analysis. There are several good reasons to start by studying this field. One very big reason is that this field is considered to be one of the, if not the most important fields of cybersecurity.
The word ‘incident’ is a very neutral word to describe the attacks on technological systems made by unscrupulous elements in society who happen to possess skills related to computers, technology, and programming. A cybersecurity specialist and especially an Incident Response and Forensic Analysis expert have the responsibility of assuming that these attacks will occur.
Having assumed this they set about the task of planning adequate responses and preventive measures which they will execute in the event of an attack. So they have to spend a lot of time, energy, mental power, and other resources in planning adequate and sufficient countermeasures which they can bring into play in the event of an attack
Contrary to what most people may think, the first thing one should learn if one wants to become a cybersecurity expert is how the hardware of computer functions. Most people jump straight to learning how to program and learning how the software part of the computing world works, and next they may even dabble in how the internet and networking works, but before all of that, they should build a strong fundamental understanding of how the hardware of computers works.
This is because the most malicious hackers and crackers attempt to sabotage a computer system by attacking and wreaking havoc on its hardware components. The process they follow to do this is called ‘bricking’ a computer system. This process is discussed in CISSP Certification.
Their line of reasoning, however uncomfortable it is to admit it, is solid and very well thought out. If the software component of a computer system is attacked and infected, it can be fixed very easily. In the eventuality that it has been damaged beyond repair, it can simply be replaced by a fresh and clean software installation of the same software components.
These days most businesses and organizations around the world back up all the data on their software applications very frequently so even the data in the affected software components can be restored relatively easily.
But when it comes to repairing affected hardware components the story is completely different. Repairing hardware components of technological systems requires actual physical intervention by technicians and hardware manufacturers. This can prove to be very expensive indeed.
In the eventuality that the hardware components are damaged beyond repair, they have to be replaced partially or completely. This is much more difficult to accomplish than repairing or replacing the software components of a technological system. Even though, this art is taught in the CISSP Certification.
So because of the high costs and a large amount of time it takes to repair and replace hardware components, malicious attackers most often target them only. So it is best for an aspiring cybersecurity expert to learn the fundamentals of the functioning and working of the hardware aspect of technological systems first.
The C programming language is the best programming language for cybersecurity. It is used in a lot of domains of cybersecurity such as cryptography, image processing, and socket networking. It is a very low-level language, just one step above assembly language and other machine-level languages. The C programming language is taught in CISSP Certification.
It is a very lean, fast, and quick to compile, and quick to execute programming language which carries a lot of benefits which are directly applicable to cybersecurity. It allows the programmer to access the internals of the hardware components of the technological systems such as the RAM, the system resources, and the system processes.
By making these parts of the computer system safe and secure by writing code and programs for their protection, the cybersecurity expert can ensure that the technological system is protected from the ground up and has solid and safe fundamentals.
The answer to this question is that yes, cybersecurity definitely requires coding. There are two aspects of any technological system – the software aspect and the hardware aspect. If a cybersecurity expert wants to ensure the safety and security of the hardware aspect he can take a lot of steps and implement a lot of safety measures and mechanisms which do not require one to learn coding.
But when the cybersecurity expert has to deal with deciding who can control the various hardware components and other miscellaneous system resources and when he has to establish a proper access/control policy for the hardware components throughout the business or organization, he has to take the help of coding. The use cases for coding are discussed in CISSP Certification.
If coding is required to ensure the safety and security of the hardware components, then what to speak of the software components? They require several complex and sophisticated computer programs and software applications to be written to protect them against computer viruses, trojan horses, worms, and other miscellaneous malware. In order to write these computer programs, the cybersecurity expert requires knowledge of coding and programming.
Cybersecurity requires a very low level of coding. The cybersecurity expert should know how to access the different hardware components of a technological system, such as the RAM, system processes, and system resources. He should also know how to write concise, fast, and efficient code so that he can keep the system resource usage to a minimum.
It takes at least 7 years to learn Cybersecurity. We are saying this with complete confidence because the CISSP certification exam has an experience requirement which states that one must have worked for at least 5 years in any 2 of the 8 domains of knowledge tested on the CISSP certification exam.
Since it takes a minimum of 2 years to gather all the requisite skills and knowledge for any major job, we can safely assume that it takes 7 years overall to reach the position where one can call oneself a learned cybersecurity expert.
This is not possible because the CISSP certification exam has an experience requirement which states that one must have worked for at least 5 years in any 2 of the 8 domains of knowledge tested on the CISSP certification exam.
