  • Organizations must stress foundational security measures to protect against cyber attacks and adhere to regulatory compliance standards.

  • The NCSC’s 10 Steps to Cyber Security provides organizations with guidelines on strengthening their cybersecurity posture.

The Importance of Cyber Security

The significance of cybersecurity lies in its ability to protect sensitive data, maintain business continuity, and ensure legal compliance. With the rapid rise in cyber attacks, it is more important than ever for organizations and individuals to implement robust security measures to safeguard their computer systems, networks, and data.

The importance of cybersecurity becomes even more evident when considering:

  • The rising costs of breaches

  • The growing sophistication of cyber attacks

  • The stringent regulatory compliance and legal requirements that organizations must adhere to

These aspects will be discussed in greater detail in the upcoming sections.

Rising costs of breaches

The repercussions of cybersecurity breaches can devastate organizations, both financially and reputation-wise. In 2021, the average cost of a data breach was approximately $4.35 million globally. Moreover, it is estimated that cybercrime costs the world economy a few hundred millions annually.

These disturbing figures emphasize organizations’ need to invest in solid security measures to safeguard their digital assets and limit the possible impact of data breaches.

The growing sophistication of cyber attacks

Over the years, the sophistication of cyber attacks, including the occurrence of a cyber attack, has increased significantly, with attackers employing advanced tactics like:

  • tailored ransomware

  • custom coding

  • exploitation of vulnerabilities

  • social engineering

Recent high-profile incidents, such as the Colonial Pipeline ransomware attack in 2021 and the Solar Winds supply chain attack, demonstrate the evolving nature of cyber threats and the need for more robust cybersecurity protocols.

As cyber criminals, also known as cyber attackers, continue improving their tactics, organizations must remain alert and adjust their security measures accordingly.

Regulatory compliance and legal requirements

Organizations such as the General Data Protection Regulation (GDPR) and the Data Protection Act 2018 must adhere to various cybersecurity regulations to avoid fines and penalties. Failure to comply with GDPR can result in fines up to $11.03 million or two per cent of the company’s annual revenue, whichever is higher.

Compliance with NIST, HIPAA, and the UK’s NIS Regulations is also essential for organizations to protect personal data and critical infrastructure. In this context, cybersecurity is crucial in protecting critical systems, maintaining regulatory compliance and mitigating legal risks.

To effectively defend against cyber threats, it’s essential to understand and address common cyber threats and attacks. This section will discuss four prevalent cyber threats:

  1. Phishing

  2. Malware

  3. Social engineering

  4. Misconfigured cloud storage

Organizations and individuals can better prepare and protect themselves from cyber attacks by using security analysts to gain insight into security threats.


Phishing is a fraudulent attempt to obtain sensitive information through deceptive emails or websites. These attacks often target personal data, such as passwords and credit card numbers, and can lead to identity theft, financial loss, and other security breaches. Remaining alert and verifying the legitimacy of requests for personal information is vital for self-defence against phishing attacks.

Some notable phishing scams have affected companies like FACC, Crelan Bank, Sony Pictures, and Facebook.

Malware and Ransomware

Malware is any software created to infiltrate computer networks, compromise data, or cause damage. Ransomware, a specific form of malware, encrypts a victim’s files and systems and demands payment for restoring access. Malware and ransomware can severely disrupt an organization’s operations and cause significant financial loss.

Organizations can safeguard their systems and networks against these malicious software attacks by implementing robust security measures, including antivirus software.

Social Engineering

Social engineering involves manipulating individuals into divulging sensitive information or performing actions that compromise security. Techniques used in social engineering attacks include:

  • Phishing

  • Scareware

  • Watering hole attacks

  • Spear phishing

  • Pretexting

  • Baiting

By understanding these tactics and being cautious of unsolicited requests for information, individuals can better protect themselves from social engineering attacks and their consequences, including attempts to gain unauthorized access.

Misconfigured Cloud Storage

Misconfigured cloud storage refers to errors or gaps in the configuration of cloud storage systems that can expose sensitive data and pose a risk to security and privacy. Inadequate security settings in cloud storage services can lead to unauthorized access and data breaches.

Organizations should follow good operational practices such as establishing visibility into the environment, appropriate security controls, implementing automated security policies, and conducting regular audits to avoid misconfiguration.
