How To Become an It Expert?
It is impossible to talk about information and communication techniques without talking about technological innovation. Since they are at the centre of all areas of life, more and more professionals want to make a career in IT. To become a right IT expert, it is essential to lay the groundwork by following an academic education to acquire the necessary foundations. Also, as in most professions, it requires particular personal qualities. The work of technological innovation offers several specializations that you should choose according to your professional aptitudes.
Have you always had a penchant for technological innovation and digital technology? Do you have a passion for solving technical problems and an unconditional love for scientific subjects? If the answer to all these questions is yes, then the computer expert’s job is probably for you. To guide them towards their development and ensure competitive and technological watch, companies all need an IT expert, a sector’s reference profession. So how do you become an essential IT expert? We tell you everything.
Acquire the Basics to Become the Right It Expert
Being an IT expert is a demanding job that requires many technical skills. This implies that you need to acquire the basics necessary to become a renowned IT expert. To this end, you must follow professional computer science training to develop the technical skills and knowledge you need.
Becoming a dedicated IT expert is planned as early as high school. First of all, you should start by obtaining a scientific baccalaureate, or Bac S as we say in France. It is also possible to become an IT expert with a Bac STI. But in the second case, it is preferable to opt for electronic engineering or electrotechnical engineering. It is these two options that can allow you to become an IT expert. If you have obtained a Bac STG option in computer science, you can also apply for the IT expert’s job.
Once you have your Bac in your pocket, you should preferably go to a computer engineering school. You won’t have to look long, as there are several such schools in France. Suppose you can’t afford to study at one of these grandes écoles. In that case, you can always continue your studies in computer science at a university that offers a wide selection of masters programs, most of which are open to aspiring IT experts.
Choosing Your Specialization
As you probably know, computer science comprises different branches. Usually, starting from the Bachelor’s degree, the student can choose a unit he wishes to specialize in. The choice most often arises between computer maintenance, embedded systems security, data science, networks and systems, etc. Given the multitude of specialities that are offered, it is best to gather all the essential information, which could influence in one way or another your choice of field of study for the specialization.
The choice will need to be based on your abilities, opportunities and other personal criteria. If you choose to specialize in networks and systems, your assignments will include developing communications solutions and techniques in all forms of communications. An expert in management informatics will have the role of setting up computer systems. They have a perfect mastery of the development of management software. If you choose to become a security expert, you will be responsible for implementing solutions to protect a company’s data. Today, when hackers and cybercriminals are the law, this profile is more and more sought after by companies.
Becoming a Computer Expert: Knowledge and Personal Qualities Required
IT jobs are particularly demanding. While it is true that diplomas are of paramount importance, they are not enough. As is usually the case, an engineer is not qualified as an engineer solely based on the knowledge they have acquired in school. They will have to make every effort to learn new skills on their own to differentiate themselves from other applicants. Fortunately, the internet is a veritable gold mine. It allows you to obtain all the information necessary to complete or add to the knowledge acquired during your training.
For example, you can watch videos on YouTube to learn more about new concepts and technologies developed in the sector. A non-IT expert should be on the lookout for information. In addition to this, he or she will need to possess several personal qualities, including :
- patience, which will be useful when faced with a problem;
- open-mindedness which will allow the expert to consider different options and alternatives to solve problems;
- Logic in all circumstances;
- the relevance of the proposed solutions;
- curiosity, which is a necessary quality to ensure technological watch.
- And finally the rigour in work, which is the driving force behind everything.
- In the end, becoming an IT expert is within reach of anyone who has the necessary skills and knowledge, but also has excellent personal qualities.
Five Steps to Becoming a System Administrator
Step 1: Obtain a University Degree (or Bachelor’s Degree) and Acquire Technical Skills.
You may be sighing that “higher education in computer science is outdated! ». But this is not the case. The majority of employers will only accept candidates for a system administrator position if they have a bachelor’s degree in a computer-related discipline, such as computer engineering or electronic engineering, and have three to five years of experience. During the three or four years of study leading up to your degree, you will learn the basics, such as the different programming languages, the types and characteristics of other operating systems and network services, how to do database and system analysis, what is involved in system design, etc. Be sure to explore internship opportunities through your institution; they will help you build a robust professional network and become a more attractive candidate once you graduate.
However, since technology is evolving much faster than textbooks, the path to becoming a system administrator also requires constant self-learning. Get in the habit of learning about emerging trends in this field by yourself: which operating systems and applications are on the rise, what new approaches are useful for hardware and software troubleshooting, what network security threats are emerging, and much more. Read industry publications and research, ask questions on the forums, chat with system and network administrators, you have tons of opportunities to dig deeper. And believe me, it’s exciting!
Step 2: Take Additional Courses to Become a System Administrator.
To increase your qualifications and improve your skills, we recommend obtaining computer science certifications, either during your graduate studies or after graduation. These certifications are optional, but employers often see them as an additional reason to consider your application. Therefore, relevant certificates help you master your skills in developing and managing computer systems and increase your chances of getting a job and expanding your choices.
Many exciting options are available to you. We recommend that you consider these three standard certifications:
Microsoft Certified Solutions Associate (MCSA)
Microsoft certifications have three levels :
- MTA (Microsoft Technology Associate) – For absolute beginners who need to learn basic technical concepts
- MCSA (Microsoft Certified Solutions Associate) – For those with basic technical knowledge and looking for their first job
- MCSE (Microsoft Certified Solutions Expert) – For experienced IT professionals who need to expand their skills to build innovative on-premise and Cloud-based solutions
Once you have completed your Bachelor’s degree, we recommend taking MCSA courses, as they focus on the latest technologies for enterprise applications, cloud platforms, data management, analytics, mobility (BYOD) and productivity. While these courses are not designed specifically for system administrators, they will help you master the art and science of designing and building solutions using core Microsoft technologies, including Windows Server.
Upon completion of the training, you will be required to write a couple of exams. To prove that you keep up with the latest technologies and continue to develop your skills, you will need to write an additional exam once a year or take other courses.
Lpic-1 Certified Linux Administrator
To test your Linux knowledge level or work specifically with this operating system, the best option is LPIC-1 – the first certification in a multi-level program established by the Linux Professional Institute. You will learn how to work in systems administration by training you to perform maintenance tasks using the command line, install and configure a computer running Linux, and set up a backbone network.
To graduate, you will need to pass two exams. Certification is valid for five years. To obtain a new certificate, you will need to pass the exams again or pass the advanced certifications before the five-year period expires.
Comp Tia Server+
CompTIA is a non-profit professional organization that issues vendor-independent IT certifications. CompTIA Server+ is a comprehensive and very intensive program. To apply for this certification, you must have between 18 and 24 months of professional experience in the field of server hardware and software. The training enables candidates to master seven core areas:
- Server architecture (configuration and support of server components)
- Server administration (server management and maintenance)
- Storage (storage device management)
- Security (physical and network security techniques)
- Networking (configuration of network connectivity systems)
- Disaster recovery (including backup plans)
- Troubleshooting a wide range of issues from hardware to security
To obtain this certificate, you must pass a 90-minute exam. This certificate has no validity period.
There are many other IT certifications. For example, if you want to work with Red Hat Enterprise Linux environments, we recommend obtaining the Red Hat Certified System Administrator certificate.
Step 3: Develop Strong Interpersonal Skills.
How to be a good system administrator This requires more than technical knowledge of Windows or Linux environments and mastery of tasks such as backups; interpersonal skills are equally important.
Since the system administrator is the first point of contact in case of a network problem, you must be prepared to work under pressure and stay calm. You also need strong problem-solving and time management skills, good judgment, and the ability to quickly and efficiently resolve problems.
Good communication skills are paramount, as you will inevitably have to come up with ideas, explain your goals and expectations for projects, and train your employees to work responsibly with IT resources. A good sysadmin is especially good at explaining complicated things to non-IT people. You must be able to turn a cumbersome or essential message into a story, for more impact. Let’s say you need to explain to an employee why choosing “Azerty” for his password is not relevant from a security perspective. You can tell them that choosing “Azerty” is indicative of a predictable and annoying user. Who likes predictable and boring people? No one does! Except for hackers, who can then easily take advantage of you. Be creative when talking to users!
People may get on your nerves without meaning to. Stay calm and watch this video from Lenovo to relax.
Step 4: Find a Job.
Before applying for a full-time job, we recommend gaining experience by doing an internship or accepting a part-time job first. You may take on junior roles in the technical support department to understand how everything you’ve studied in theory works in practice. Real-world experience is the best training available.
Once you’ve tested and honed your skills in the field, you’ll be able to get your first job as a System Administrator or Network Administrator, as these roles often overlap. Employers are often looking for candidates with at least 3 to 5 years of experience, but you may be able to include your education and internships in that time frame. Use the contacts you’ve made in the field; your network is your best ally in getting a job. You can also search for jobs via LinkedIn, Monster or Indeed, targeting jobs that match your skills and salary requirements. If you’re familiar with a particular operating system or have a certification in a specific field, be sure to highlight it on your resume.
When choosing between large or small companies, think twice before rushing into a multinational. You will probably gain more experience in a small company because small organizations often lack staff and budget; you will have to juggle many projects and learn to do many things simultaneously, which will require you to improve your automation skills. Choosing a large company runs the risk of having a narrow area of responsibility and ending up with a less exciting experience.
Step 5: Constantly Update Your Knowledge.
Once you’re up to speed and no longer need to google “How to Become a System Administrator,” your journey is not over. It will never be around; you will always have to keep up to date with the latest technologies, evolving quickly. Consider joining a professional network, such as the League of Professional Systems Administrators (LOPSA), whose goal is to advance the practice of systems administration and educate professionals and the general public about systems administration issues. LOPSA offers excellent training and networking opportunities through online events and shares useful information in Slack and its RSS feeds and mailing lists.
Spiceworks is another gold mine of knowledge for system administrators: a vast international community for everyone who cares about the IT industry’s future. We recommend reading the articles published there, as they contain valuable training content and balanced product reviews. You can also check out Microsoft Technet and Reddit, but with Reddit, you’ll have to explore a wealth of fun but irrelevant threads, so don’t spend too much time on them when you’re at work.
6 Tips for Becoming a Security Expert
Tip 1: Get Adequately Trained to Become an It Security Expert
IT security experts often refer to gifted hackers who are prodigiously gifted in their disruptive methods. However, most of the paths to becoming an IT security expert are academic.
Related: The Future of Network Maintenance Technician Training
This type of training leads to the development of a good knowledge of the various types of existing architectures and methods and the rules and acceptable practices to be maintained. This generally requires a bachelor’s degree, a Bac+5 or an engineering school.
Suitable training has the notable advantage of allowing practitioners’ cumulative experience in the sector to be acquired and knowledge that, although conventional, nevertheless provides information on multiple techniques designed to improve cybersecurity.
Tip 2: Have a Good Command of Systems
One of the main concerns for anyone aspiring to become an IT security expert is the system in place within the structure that needs to be secured. The architecture of this system, its reliability and its fragilities must, therefore be very carefully controlled.
Awareness of the shortcomings identified, correcting them and reinforcing the strengths, in short, optimizing the system, is a work in progress. For this, it is necessary to demonstrate factual knowledge in specific disciplines:
- Network administration ;
- System development ;
- Encryption and cryptology.
It is also necessary to have a clear vision of the hierarchy to be established between the various parts of the IT system to be secured.
Setting up an IT security policy and drawing up a charter for this purpose makes it possible to codify access mechanisms, sharing and monitoring rules, and the uses that users can make of the various tools available.
Tip 3: Understanding the Need for Control
Become an IT Security Expert: Understanding the Human Factor
Still referred to as “table-chair” risk, the human factor corresponds to the share of risk inherent to a computer system user. Becoming an IT security expert requires a keen awareness of this risk.
One of the most concrete manifestations of this risk relates to non-validated Cloud applications by an organization’s workers. These are generally open-source storage solutions that offer no guarantee of security for the data hosted in them.
Neither the organization nor the security expert has any control over who can access the elements stored there. This risk is severe when it concerns personal or confidential professional data.
The solution in this respect generally involves making employees aware of the risks associated with such practices and the caution they should exercise. The IT charter mentioned above can be used as a tool to increase this awareness.
Raising awareness should also raise employees’ awareness of risks such as :
- The usual scams;
- Passwords that are too weak;
- Multiple-use passwords;
- The introduction of personal USB keys;
- The sharing of confidential business information;
- Automatic opening of attached files sent by strangers.
Therefore, becoming an IT security expert requires being able to limit the risk linked to the human factor by making staff responsible. The establishment and popularization of procedures to be followed in the event of loss of sensitive computer equipment also contributes to this approach.
Control Wi-Fi Access
Many organizations and companies have Wi-Fi hotspots installed on their premises for the benefit of their employees. Sometimes unsecured, these openings that provide access to the internal network must be systematically monitored closely to secure data flows.
In the case of a Wi-Fi hotspot with a long-range, it may even happen that the opening thus provided is accessible from outside the physical perimeter of the business premises. An unauthorized person can then connect to it, which constitutes a significant loophole and a risk of hacking.
To this end, becoming an expert in IT security implies using adapted and correctly dimensioned equipment, configure such networks properly and ensure appropriate control of these access points.
Controlling Internet Access
Access control is more than just thwarting intrusions from outside. Becoming an expert in computer security also requires the ability to control outgoing flows. To do this, the use of a hardware or software firewall may be necessary.
This tool offers the possibility of filtering all content that passes through Internet accesses, without preventing workers from accessing the Web. Regular monitoring of the list of sites and resources considered to be at risk makes it possible to block all exchanges with such sites.
Such an approach is amply justified because each of the company’s Internet access points can become an exploitable opening for an attack against the computer system when faced with specialized skills.
Thus, for example, in the case of a system deployed on several physical sites and networked, a practical approach can consist of :
- Limiting the number of Internet accesses ;
- Setting up a virtual private network;
- Provide the entire network with a single access to the internet.
This type of approach simplifies control by reducing the number of access points that need to be monitored.
Tip 4: Be Paranoid
Being focused on backup
Becoming an expert in computer security implies being always able to ensure professional data’s safety and durability. In addition to attacks, computer system failures can jeopardize the security of said data.
An efficient way to deal with such eventualities is to implement a data recovery solution. This type of solution also protects against ransom attacks.
When an organization can retrieve a recent backup of its data, it does not have to pay the hackers who caused the attack. However, this requires that these backups have been stored in a separate location from the attacked one.
One of the qualities to be developed to become an expert in computer security is to consider that an attack is always imminent and likely to occur.
This awareness develops quickly when you know that automated systems are constantly scouring the Web looking for weak points to attack connected computer systems. No security is, therefore, definitive.
New vulnerabilities are continually being discovered, and new attack methods are continuously being developed. Keeping this reality in mind makes it possible to react appropriately to effectively ensure the computer system’s protection under one’s care.
Tip 5: Become a Computer Security Expert: Reinforce Your Experience
Suppose good training allows one to get used to the different types of systems that may exist. In that case, it is advisable for anyone wishing to become an IT security expert to diversify their work environments. This makes it possible to be confronted with multiple architectures and systems.
This diversity offers the advantage of enriching the experience that a worthy IT security manager can boast of. The various positions held within successive organizations also help flesh out the career path of a person who aspires to become an IT security expert.
In the sector, organizations’ budgets have been increasing for several years, and many jobs are regularly created. It is, therefore, relatively easy to strengthen one’s experience.
Tip 6: Maintain Technology Watch
Computer attacks are constantly being perfected and evolve to surprise computer systems and their managers. Hackers use their imagination and creativity to thwart known protections successfully.
In response to this, dynamism & in response to hostility, the flaws discovered in systems, software, applications and tools are frequently updated to provide fixes. Monitoring these two areas is essential if you want to become an IT security expert.
Since updates are provided free of charge by software vendors, it would be a waste not to stay informed to take advantage of them and strengthen the security of the systems you are in order of. Learn more here about the usefulness of updates.
Similarly, it is useful to keep abreast of the procedures and protocols used to thwart, contain or support the most common attacks. It is also essential to be familiar enough with them to respond appropriately without losing control.
