How Can I Learn Cyber Security from Scratch ?

Starting a cybersecurity career has never been easier with various online training tools and a good job outlook. Cybersecurity analysts are in charge of keeping an eye on computer infrastructure and information systems to guarantee safe from cyber threats. 

They do so by employing a multi-pronged strategy to prevent, detect, and de-escalate cyberattacks:

  

• Putting in and keeping cybersecurity controls in place (a measure that companies deploy to prevent, detect and counteract cybersecurity threats)
  
• Penetration testing is a type of ethical hacking to evaluate an organization's current cybersecurity defenses.
• Monitor a company's network for security flaws and report them.
• As a foundation for containing and counteracting a cyberattack, create contingency plans and business continuity plans (BCP)
• In the event of a security breach, respond by conducting a forensic investigation to discover the nature of the threat, which usually involves malware or ransomware.

Cybersecurity professionals can work in a variety of industries, including aerospace and healthcare. When there is a transmission of sensitive data across a computer network, cybersecurity measures are required to prevent the system from being hacked by individuals looking to steal identities or corrupt a network or computer system to extract a ransom. 

Let us consider a few points to help you start a career and learn cybersecurity from scratch

Find out if a career in cybersecurity is appropriate for you

Before proceeding in this career path, the foremost thing to do is to check yourself and ensure that the field interests you and is suitable for you. 

Cybersecurity experts must keep up with the latest developments to prepare an adequate defense as cybercriminals constantly develop new tools and techniques. Cybersecurity professionals must also advocate for security best practices within their company and collaborate with other departments. If you work for a software firm, this may include meeting with project managers regularly to provide robust security measures during the software development life cycle. In a retail setting, a cybersecurity professional works with the finance and legal department. 

A desire to learn new technologies, programming languages and industry trends is essential for a successful cybersecurity profession.

Making a professional decision

One of the key benefits of a cybersecurity profession is the freedom to shift between industries. While each company has its approach to cybersecurity, legal restrictions make some businesses more secure than others. A person working in banking and financial services will have exposure to a broader range of cybersecurity solutions than someone working in education.

Obtain the requisite cybersecurity knowledge and abilities

While there are numerous sub-disciplines in cybersecurity, such as network security and risk management, many occupations share a technical foundation. An entry-level cybersecurity analyst position often requires a bachelor's degree in computer science, programming, or engineering.

Those without a computer science background can attend a cybersecurity boot camp. However, some organizations will still require a bachelor's degree (even in a completely unrelated discipline) for liability reasons.

For mid to senior-level employment, some organizations or businesses may also require a Master's Degree and several years of network experience. Certain positions in the industry need a Cyber Security professional certification to qualify for the post. This certification entails a professional's familiarity with the stack, Amazon web services, Google platforms, Azure, and Cisco.

There are various institutes and training centers that provide cyber security courses online. To grow and accelerate your career path, signing up with an institute that has the reputation of offering the best practices and cyber security certifications that are in demand in the market.

Selecting the Correct Certifications

Generalized programming or cybersecurity abilities alone will not get you very far in your cybersecurity profession, especially with the introduction of cloud computing and increasingly complex cyberattacks. Acquiring a Cyber Security professional certification is a mandatory step to progress in the field. Cyber Security certifications demonstrate that you are knowledgeable in a specific field, such as network administration, or familiar with a particular vendor's products and services. The International Information System Security Certification Consortium (ISC)2 found that a degree and certifications were frequently a primary influence in employment in a recent poll.

Improve your abilities through regular practice

Free tools and free trials for paid software products have made it so easy for cybersecurity students to practice their abilities outside of traditional courses that those who don't are at a disadvantage. While formal credentials are essential, teaching oneself as many peripheral skills as possible is the best way to differentiate oneself for a cybersecurity career.

 A virtual lab is an excellent location to put your skills to the test. A virtual lab is a simulated environment that includes cybersecurity vulnerabilities and protections, including malware, databases, firewalls, and encryption standards, among other things. You can establish your virtual lab using a system like VirtualBox to build and test various security measures.

You can also make use of the one-year free 25 services that Microsoft Azure offers and the free tier that Amazon Web services provide for 750 hours.

Develop your technical abilities

Knowledge of information systems, network security, and cryptography and the ability to build Python scripts and execute penetration tests to analyze the effectiveness of your cybersecurity defenses are all essential technical skills for a cybersecurity analyst. You must also be familiar with operating system architecture, administration, and management, as well as networking and virtualization technologies.

Entry-level cybersecurity employment may not require possessing programming abilities. However, as your career progresses and becomes more specialized, writing and understanding code becomes increasingly vital. When investigating a security breach, a penetration tester, for example, must uncover holes in the source code and figure out how to exploit them. In contrast, an incident responder must scan the source code for malware. C, C++, Python, and Java are all recommended programming languages to master.

The ideal way to equip oneself with industry-relevant skills is thus to go for Cyber Security professional training.

Prepare a cybersecurity CV and portfolio

When applying for a cybersecurity job, cover letters aren't as important as they once were. What matters most is that your resume demonstrates practical experience. 

A technical resume should showcase critical skills that allow a recruiter to see the link between your abilities and the job needs. List particular functions you know how to execute instead of a dry list of technologies and programming languages you know.Internships are a terrific opportunity to demonstrate any real experience, but you also need to prove that you are willing to learn new technologies on your own. 

In the interview, your experience in a penetration test may help you perform better. There are high possibilities of the interviewers asking you to analyze telemetry data, identify the source of a security breach, and provide a remedy. Beginners or those aspirants at the entry-level should also be conversant with incident response protocols like escalation procedures and triaging to communicate through their thought process even in the absence of the knowledge of the right solution.
