Cybersecurity: The key to sustainable growth in the securities Industry

The global stock market, with a total market capitalization estimated to exceed $100 trillion by the end of 2023 according to Banking Journal, plays a crucial role in connecting businesses and investors, thereby driving economic growth. Amidst unprecedented technological advancements, the digitization process is vigorously unfolding in the securities industry, ushering in numerous new development opportunities. However, alongside these significant benefits, this process also harbors various cybersecurity risks, necessitating comprehensive security solutions and attention. This article will delve deeper into the benefits, challenges, and optimal security solutions for businesses in the digital era of the securities industry.

Digitization - Benefits and Risks in the securities industry

Digitization is driving significant changes in the securities industry, bringing numerous benefits while also presenting considerable challenges for businesses operating in this field.

Benefits of Digitization

Digitization has brought significant benefits to the financial market, particularly in enhancing transaction efficiency and transparency. According to a report by the International Data Corporation (IDC), the adoption of digital technology, along with technological solutions that optimize performance in financial transactions, has helped reduce operational costs by up to 30% and shorten transaction processing time by 50%.

Specifically, online trading platforms allow investors to execute transactions anytime, anywhere, with significantly improved order matching speeds. This not only increases market liquidity but also opens up opportunities for individual investors to access a more diverse range of financial products. Additionally, the rapid and transparent disclosure of market information on digital platforms has played a crucial role in improving the quality of investment decision-making.

Risks of Digitization

According to a report by Cybersecurity Ventures, global damages from cybercrime are projected to increase from $3 trillion in 2015 to $10.5 trillion by 2025. Financial exchanges, which hold vast amounts of sensitive customer and transaction data, have become attractive targets for cyberattacks.

The increasing reliance on technology by financial exchanges has opened the door to numerous potential risks. Hackers can exploit security vulnerabilities to steal sensitive data, causing significant damage to investors and businesses. Sophisticated cyberattacks can cripple trading systems, leading to market chaos. Additionally, technology facilitates fraudulent activities such as stock price manipulation and insider trading, making them more sophisticated and harder to detect. Even minor technical glitches can lead to significant disruptions due to over-reliance on technological systems.

To address these challenges, financial exchanges must invest heavily in cybersecurity systems, develop robust risk management processes, and regularly update their knowledge of emerging threats. Collaboration with cybersecurity experts and regulatory authorities also plays a crucial role in ensuring the safety of trading activities and protecting investor interests.

The negative impact of cyberattacks on the securities industry is profound

Cyberattacks pose not only a threat to individual businesses but also can lead to significant repercussions for the entire securities industry.

Cyberattacks cause a decline in stock prices

A 2022 study by Sustainalytics has highlighted significant negative impacts of serious cyberattacks on stock prices. Analyzing data from 69 cyber incidents with high risk levels, the study indicates that the stock prices of companies affected by these attacks decreased by an average of 2.3% within 4 days of the incident and continued to decline to 4.6% after 60 days.

Furthermore, by the end of the year following the attacks, the stock values still showed an average decrease of 0.65% compared to the market's average growth rate of 8.47%. This demonstrates that cyberattacks not only cause immediate damages but can also have long-term implications on a company's valuation.

The impact of cyberattacks on the stock market varies by country and region

The study 'The Impact of Data Breaches on Stock Performance 2019' has demonstrated that the impact of cyberattacks on the stock market is not uniform but varies depending on each country and specific context. For companies in the UK, stock prices typically decrease by an average of 0.77% immediately after the disclosure of a cyberattack. In contrast, in France and Germany, cyberattacks not only reduce stock prices but also immediately turn average company profits negative.

This illustrates the varying sensitivity of investors to cybersecurity incidents across markets, where market reactions are influenced by factors such as the severity of the attack, the information disclosed, and the general economic environment.

Tech companies are often seriously affected

Although data breach disclosures do not always cause significant stock price fluctuations, the real-world consequences for businesses can be severe. Cases like Equifax and ADP demonstrate that losing customers and facing legal penalties after data breaches can result in substantial financial damage. In particular, technology companies often experience more severe impacts and require significant time to regain trust from customers and partners.

Furthermore, ransomware attacks can also lead to significant market capitalization fluctuations. The impact and recovery ability of businesses depend on various factors, including the scale and nature of the attack, as well as the cybersecurity measures the company has implemented. This underscores the importance of investing in cybersecurity to protect the assets and reputation of businesses in the digital age.

The forms, typical examples of cyber attacks in the securities industry

DDoS attack targeting the NZX stock exchange in New Zealand caused trading to be temporarily suspended for 3 days

Cyberattacks not only directly harm companies but can also target stock exchanges, causing serious consequences for the entire market. The objective of these attacks is often to disrupt trading activities, manipulate systems, thereby eroding investor confidence and causing sharp declines in stock prices. A prominent example is the Distributed Denial of Service (DDoS) attack on the New Zealand Stock Exchange (NZX) in August 2020. This attack forced the exchange to halt operations for three days, resulting in significant loss of trading time and opportunities for investors. Additionally, NZX faced trading volume issues and was unable to settle securities transactions and bonds during that month.

Furthermore, the attack severely damaged NZX's reputation, leading to negative public and expert commentary. A report by the Financial Markets Authority (FMA) subsequently highlighted NZX's inadequate technological resources and insufficient information security, citing weak network architecture and incomplete infrastructure protection.

Motives behind cyberattacks in the securities industry

The securities industry plays a crucial role in the global economy, making it a prime target for sophisticated cyberattacks. Understanding the motivations behind these attacks is essential for preventing and mitigating risks to investors and the broader economy. The primary motives driving cyberattacks in the securities industry include:

  • Financial Gain: This is a major driving force behind many cyberattacks. Attackers seek to profit by manipulating stock prices or other assets through market manipulation attacks. Small firms with limited cybersecurity investment are often more vulnerable to these attacks and fraudulent activities.
  • Political Objectives: Cyberattacks on the securities industry can also be linked to political goals. Attackers may carry out attacks to create economic instability or weaken a particular government.
  • Revenge: This can be a personal motivation. Attackers may target stock exchanges to recoup previous financial losses or harm competitors.
  • Threats and Extortion: Attackers may orchestrate securities market attacks to threaten or extort financial institutions or investors, often involving ransom demands.

Digitalization brings many benefits to the securities industry, but it also comes with risks that need to be addressed and resolved. In addition to cooperation and raising cybersecurity awareness among stakeholders such as the government, financial institutions, and investors, businesses also need to ensure cybersecurity to promote safe and effective digitalization, contributing to the development of a sustainable and transparent securities market.
