Cybercrimes may be a relatively new phenomenon, but in a short span of time have become as hazardous as terrorism. According to IT Governance Limited’s quarterly review of cyber security incidents, the total number of breached records in the first quarter of 2022 stands at 75,099,482. A report by consulting and service providing firm Accenture shows a 31 per cent jump in the average cyberattack numbers per company since 2020.
As ransomware attacks, data breaches, and significant IT outages are on the rise, nations and institutions are consistently increasing their spending on cyber security. As per the research firm Gartner Inc., the total cyber security spending in 2021 was estimated at USD 150 billion, more than 12 per cent from 2020. The research firm also predicts that the global spending on cyber security will proliferate with the increase in the number of rising threats and cyber security solution costs.

You must have gained a shallow understanding of how critical cyber security is, but do you know why it has become an undeniable need of the hour? We all have prized possessions, such as a piece of jewellery, family pictures, or a laptop. Like these prized possessions, data is a form of new and the most vulnerable possession for individuals and businesses in the digital age.
We often find many data breaches or other cyberattacks news making headlines in the newspapers daily, affecting millions of consumers and companies. Institutions prepare themselves for a rash of cyber strikes through various methods, including penetration testing, ethical hacking, or risk assessment.
For individuals and businesses, understanding the broader advantages and disadvantages of cybersecurity can make it easier to understand why security measures are necessary while also recognizing the challenges involved in implementing and maintaining them.
What does cyber security entail?
Before we delve into the cyber tutorial, let us walk you through the basic understanding of cyber security. In essence, cyber is the technique of protecting confidential and sensitive data, computer systems, networks, devices, applications, and software from being attacked or tampered with.
At present, there is a broad range of cybercrimes, such as ransomware, phishing, trojan virus, SQL injection, denial-of-service, and DNS Tunneling, to name a few. Cybercriminals are now using more sophisticated ways of attacking data. Therefore, governments and institutions are gearing up to protect a variety of sensitive data from the risk of theft and damage.
Cyber security also involves protecting information while it is being stored or transferred between systems. One important technology used for protecting sensitive information is encryption, which helps transform readable information into a protected form. Understanding the role of encryption keys can provide beginners with a better foundation for understanding how encrypted information is protected and accessed.
Cyber security is not limited to computers and traditional networks. As more devices become connected to the internet, security concerns are also expanding to smartphones, smart home devices, industrial systems, and connected vehicles. The automotive industry, for example, increasingly depends on software, wireless communication, and connected systems.
Connected vehicles can contain infotainment systems, onboard computers, Bluetooth connections, navigation services, and other technologies that communicate with external devices. This creates additional areas where security needs to be considered. Drivers and vehicle owners can learn more about these concerns by exploring the things to know about automotive cybersecurity.
For beginners, one of the most important concepts to understand is that cyber security is a continuous process rather than a one-time activity. New vulnerabilities can appear as technologies change, and attackers continuously develop new methods. Organizations therefore need to regularly review their security practices, update software, monitor systems, and educate employees.
Strong passwords are another basic part of personal cyber security. Users should avoid using the same password across multiple accounts and should choose passwords that are difficult to guess. Where available, multi-factor authentication can provide an additional layer of protection by requiring another verification method in addition to a password.
Software updates are equally important. Developers regularly release updates to fix bugs and address security weaknesses. Delaying updates for long periods can leave devices exposed to vulnerabilities that may already have known solutions. Users should therefore install legitimate updates from trusted sources whenever possible.
Phishing is another common threat that beginners should understand. A phishing message may attempt to convince a person to click a malicious link, download an unsafe file, or provide sensitive information. These messages can sometimes look like legitimate communications from banks, companies, websites, or other trusted organizations.
Users should carefully check unexpected emails and messages before responding. They should avoid providing passwords, financial information, or other sensitive details through suspicious links or unfamiliar websites. When in doubt, it is safer to visit the official website directly rather than following an unexpected link.
Businesses also need to protect their networks and data from unauthorized access. This can include firewalls, endpoint protection, access controls, security monitoring, backups, encryption, and employee awareness programs. The exact security measures required will depend on the organization’s size, technology environment, industry, and risk profile.
Backups are particularly important when dealing with ransomware and other destructive attacks. Maintaining secure and reliable copies of important data can help an organization recover if its primary systems become unavailable. Backups should also be protected from unauthorized access so that attackers cannot easily compromise both the original data and its backup copies.
Why is a cyber security degree totally worth it?
Pursuing MCA in cyber security can be an enticing and lucrative career move, opening doors to many stellar cyber security jobs. As all roles in the cyber security domain are financially rewarding, a degree in cyber security could be a better return on investment.
According to Glassdoor, an entry-level cyber security analyst in India makes INR 5,04,875 a year. The salary of an experienced cyber professional goes up to INR 36,00,000 per year in India, Glassdoor suggests.
A career in cyber security can involve many different areas, including security analysis, ethical hacking, penetration testing, incident response, security engineering, cloud security, digital forensics, and risk management. Students interested in the field can begin by developing a strong understanding of computer networks, operating systems, programming fundamentals, databases, and basic security concepts.
Practical experience can also be valuable alongside formal education. Building small projects, learning about common vulnerabilities, practicing in authorized cybersecurity laboratories, and understanding how defensive security tools work can help students develop useful technical skills.
Cyber security professionals also need strong problem-solving abilities. Security incidents rarely follow exactly the same pattern, so professionals may need to investigate unfamiliar activity, identify potential weaknesses, and determine appropriate responses. Communication skills are important as well because security teams often need to explain technical risks to managers, employees, customers, and other stakeholders.
As organizations continue to depend on digital infrastructure, the demand for people who can help protect systems and information is expected to remain important. However, students should choose their education and career path based on their interests, skills, and long-term goals rather than salary alone.
