One of the largest cyberattacks ever was the Yahoo! data breach in 2013, which exposed an astounding 3 billion accounts. Hackers were able to fully access the users’ email accounts, including their calendars. If a big company like Yahoo couldn’t protect itself from cyber threats, you might think that it’s not likely that any company is 100 percent safe. The proliferation of the internet and smart gadgets has increased the vulnerability of businesses to cyberattacks. According to recent trend research, the cyber security industry will nearly reach a value of $200 billion by 2027. To keep their data secure, firms must prioritise cyber security. We will learn all about cyber security in 2023 in this blog!

A cyber security expert works to keep computer systems and data safe from being hacked or stolen. Online businesses have become a top target for fraudsters wanting to access sensitive data, as a result of the internet revolution by Reliance Jio, which has increased the need for qualified cybersecurity personnel. Cyber security experts should be able to think strategically, stay current on new developments, and spot suspicious signals.

Two key responsibilities of cyber security professionals are: –
– Collecting information on current security measures for threat assessment and maintaining frequent records.
– Regularly testing the systems for attacks and, if any are found, putting the required preventive measures in place.
Network security, information security, and Infrastructure security are 3 common types of cyber security.

Network security is the branch of cyber security concerned with protecting devices from network intrusions. Firewalls, physical security devices, and security awareness are all used by network security experts to stop breaches. Information security is, in some ways, a subcategory of network security. Information security takes into account elements like data confidentiality and accessibility to block access by cybercriminals. Building and maintaining infrastructure for systems is the focus of infrastructure security to shield them against intrusions.

Skills required for Cyber Security
– Technical Adaptability: – Professionals need to have a firm understanding of computer networking and how it works. They should also be knowledgeable about common security problems and how to fix them.
– Thinking Like Hackers: – To protect systems from attack, professionals must understand how hackers think and act. This knowledge allows them to foresee attacks and implement efficient responses.
– Problem-Solving: – Cybersecurity challenges are frequently intricate and varied. Experts need to be able to identify problems and create creative solutions by employing their problem-solving abilities.
What are the job roles in Cyber Security?
– Application Security Engineer: – The majority of their time is spent on designing and debugging softwares. Application security experts help in creating and implementing plans to protect the safety of a company’s systems and goods.
– Network Security Engineer: – Engineers in network security are needed to build and run the hardware and software used for network security.
– Information Security Engineer: – They are responsible for looking into security problems and offering patches. The duties include studying the industry, spotting potential problems, and putting security measures in place.
– IT security Analysts: – To understand how cyberattacks occur and what can be done to prevent them, they study the security plan for the organisation and prior violations.
Is Cyber Security as a career worth it?
The need for cybersecurity experts will continue to grow until some unknown force doesn’t completely wipe out the internet on Earth. No military or government wants someone to know where their nuclear warheads are hidden, and no government wants its confidential documents exposed. Furthermore, no private company would like to allow a hacker to learn its trade secrets. Cybersecurity professionals who are knowledgeable in this field and capable of fending off such dangers are needed to detect such threats.
