What is Cybersecurity: A Comprehensive Guide

by | Nov 7, 2023

What is cybersecurity? In essence, cybersecurity protects systems, networks, and programs from digital attacks aimed at assessing, changing, or manipulating sensitive information, extorting money from users, or disrupting normal business operations.

Cybersecurity encompasses all aspects of protecting an organisation and its assets from cyber threats. With increasing cyberattacks’ sophistication and complexity, various cybersecurity solutions are essential.

A strong cybersecurity strategy provides a solid security posture against malicious attacks designed to access, alter, delete, destroy or extort an organisation’s or user’s systems and sensitive data. Cybersecurity is also crucial in preventing attacks that disable or disrupt a system’s or device’s operations.

With the growing number of users, devices, and programs in modern enterprises, combined with the increased deluge of data, the importance of cybersecurity continues to grow.

Learn more and understand how we can make our cyberspace safer.

The Paramount Importance of Cybersecurity

The importance of cybersecurity has never been more pronounced than it is today. With a surging number of users, devices, and programs in modern enterprises, alongside a growing volume of data—much of which is sensitive or confidential—the need for robust cybersecurity measures is imperative.

The escalating volume and sophistication of cyberattacks, coupled with the evolving techniques employed by cybercriminals, further exacerbates the issue. In 2022, Singapore witnessed a staggering 25.2% increase in scams and cybercrimes, with 33,669 cases reported. This surge highlights the critical need for enhanced cybersecurity awareness and skillsets in the region.

Moreover, employers are on the lookout for individuals equipped with cybersecurity knowledge. Whether you’re aiming to elevate your career by acquiring cybersecurity skills or venturing into the thrilling realm of the cybersecurity industry, our certification course is tailored just for you.

Leading Cybersecurity Challenges That You Should Know

Cybersecurity faces top challenges, including evolving threats, a data deluge, cybersecurity awareness training, workforce shortage and skills gap, supply chain and third-party risks. 

Evolving Nature of Cyber Threats

One of the most significant challenges in cybersecurity is the evolving nature of security risks. As technology progresses and is used in new ways, new attack avenues are developed. This necessitates continuous updates to cybersecurity practices and can be particularly challenging for smaller organisations with limited resources.

Data Deluge Issues

Collecting vast amounts of data increases the likelihood of cybercriminals wanting to steal personally identifiable information (PII). Organisations must take steps to prevent breaches, especially when storing PII in the cloud.

Cybersecurity Awareness Training

Employees can accidentally bring threats into the workplace or act insecurely, such as clicking links in phishing emails. Regular security awareness training is essential in helping employees contribute to their company’s cybersecurity. Online cybersecurity courses are now widely available in Singapore, which is a good sign of learning it everywhere.

Workforce Shortage and Skills Gap

The need for skilled cybersecurity staff grows as the data businesses use increases. The workplace gap between needed cybersecurity jobs and security professionals was estimated at 3.4 million, according to ISC2. Singapore’s government is working tirelessly to meet this gap by making awareness campaigns and offering subsidies to help learners.

Supply Chain Attacks and Third-Party Risks

Supply chain attacks and third-party risks are becoming increasingly complex security challenges. Organisations must address third-party risk in the supply chain and reduce software supply issues, for example, by using software bills of materials. 

These challenges can profoundly impact the future of cyberspace, but how can we help? Let’s discuss the main types of cybersecurity threats and what we can do to address these ever-evolving problems.

Main Types of Cybersecurity Threats

The digital world is fraught with numerous cybersecurity threats that can have severe implications for individuals and organisations alike. From malware to phishing and beyond, it’s vital to understand these threats to protect yourself and your assets. Let’s delve into the main types of cybersecurity threats that pose risks in today’s interconnected world:

Distributed Denial-of-Service (DDoS) Attacks

DDoS attacks involve multiple systems overwhelming a target’s network resources, such as a server or website, to disrupt its functionality and deny access to legitimate users.

Man-in-the-Middle (MitM) Attacks

MitM attacks involve an attacker intercepting and relaying messages between two parties. They are communicating directly with each other to eavesdrop or manipulate the conversation.


Ransomware is malicious software that is designed to block access to the computer system or files until a ransom is paid. Paying the ransom doesn’t guarantee system restoration or file recovery.


Phishing involves sending fraudulent emails that mimic reputable sources to steal sensitive data. Examples are credit card numbers and login information. It’s a common attack type, and protection measures include education and email filtering solutions.


Malware is software created to gain unauthorised computer access or cause damage. It includes various types, such as viruses, spyware and more!

Social Engineering

Social engineering manipulates individuals into revealing sensitive information or making monetary payments. Tactics include phishing, pretexting, and baiting.

Spear Phishing

Spear phishing is a targeted phishing attack aiming to steal information or infect the system of a specific user, organisation, or business.

Insider Threats

Threats come from individuals within the organisation, such as employees or contractors, who cause security breaches, either maliciously or negligently.

Advanced Persistent Threats (APTs)

APTs are prolonged, targeted attacks where an intruder infiltrates a network, remaining undetected for extended periods with the goal of stealing data.

For those interested in tackling these threats and playing a vital role in safeguarding cyberspace, exploring career opportunities in cybersecurity is a commendable step. There are diverse and in-demand roles available in this field. Learn more about these career opportunities and find out how you can make a difference.
