Why Is It Necessary to Quantify Cyber Risk?

Knowing which dangers to address first might be difficult given the number of hazards that modern businesses must contend with. Using a method called risk quantification, you can prioritise problems based on which problems are most likely to happen or to cause the most substantial harm.

Not all cyberattacks in Hong Kong can be stopped using this technique. Non-quantifiable or qualitative risks are more subjective and cannot be described in monetary terms (such as lost revenues). You can find out what risks your company faces and how to measure them with the help of a quantitative risk assessment (QRA). Although risk quantification has its roots in the finance industry, it is increasingly used in cybersecurity. Much like a financial institution will take chances to make money, cyber threats usually increase when a company is growing and expanding.

For many businesses, risk quantification can be a useful technique. You can decide if it’s a good option for your company by understanding the benefits, drawbacks, and best practices. Many businesses can benefit from the use of risk quantification. A fantastic strategy to describe your risk picture to board members and other stakeholders is to have readily available standard metrics.

This information might be useful for financial planning, mergers, and inquiries regarding cybersecurity investment as your company grows and expands. Also, it is usually a good idea to use a “single language” to inform all employees of your company’s risk mitigation initiatives. Quantitative information in Hong Kong also enables you to track your advancement over time. You will be able to determine with certainty whether your risk management measures are adequate and whether your cost projections are accurate with the help of this data. Data is reliable and will be useful for building your risk register and establishing a productive risk management program for your business.

What Kinds Of Cyber Risks Are Most Typical?

Cybersecurity dangers are widespread and can be recognized and avoided. The security risks that businesses currently face will be examined in this essay. According to Rani Jarkas, Viruses and malware: Spyware, ransomware, viruses, and worms are examples of malicious software. When a user clicks on a bad link or attachment, malware might be activated to distribute dangerous software. Upon installation, the malware can: 

• Block access to crucial network components (ransomware)
  
• the installation of more possibly dangerous software
  
• Transfer data from the hard drive to acquire information covertly (spyware)
  
• cause the system to become dysfunctional by interrupting certain areas
  

According to the Cybersecurity and Infrastructure Security Agency, Emotet is a strong, modular banking Trojan that primarily functions as a downloader of other banking Trojans (CISA). Regrettably, Emotet is still among the most expensive and harmful spyware.

Interruption Of Services

A denial of service attack (DoS) shuts down a network or website by flooding a computer or network with requests. A distributed DoS (DDoS) attack employs a large number of devices, or botnets, to swiftly accomplish the same goal.

The “handshake” protocol is frequently interrupted by cybercriminals using a flood attack to launch a DoS. Different strategies are occasionally employed, and some cybercriminals carry out additional attacks while the network is offline. By infecting millions of machines with software, a hacker can take control of a botnet, a sort of DDoS.

Attacks By “Man-In-The-Middle”

When hackers interject themselves into a two-party transaction, a man-in-the-middle (MITM) assault takes place. Once communication between the two parties has been blocked, the attacker can filter and gather data in Hong Kong. When a visitor utilises an unprotected public Wi-Fi network, MITM assaults frequently occur. Attackers block access to the web by using malware to steal data and install software.

Phishing.

Phishing attacks impersonate legitimate-looking email accounts to trick a target into opening an email (like a coworker, for example). The message will have the user click on a harmful link or divulge personal information while pretending to be from a legitimate source. Direct device infection of the user is desired, as is the theft of critical information like passwords and credit card details.

• Injection of SQL: When a SQL server becomes attacked with malicious code, a SQL injection occurs. Data is released when a server is attacked. The malicious code only has to be entered into a search field on a weak website.

• Password attacks: A cyber attacker can gain access to a lot of information with the right password. Accessing a password database or attempting to guess passwords are examples of password assaults.

How Can Cyber Risk Be Calculated?

It might be challenging to define the best practices for risk assessment, a quickly developing but yet relatively new area of cybersecurity. When deciding whether risk quantification is appropriate for your business, there are a number of factors to take into account. Adapt a Model to Your Requirements. Any model your company uses will make an effort to determine the potential “value at risk,” or VaR, of each cyber risk. Quoted from Rani Jarkas, the financial expert in Hong Kong, Yet, there are several ways to model risk and get the datasets you want. When developing your risk assessment matrix, pay close attention to the variations between these models.

One popular model is the Monte Carlo analysis (or Monte Carlo simulation), which enables you to examine every potential result of a given risk. There are other models as well, and you can choose one with a technique that works for your company and makes decision-making easier.

Recognize That Measuring Risk Is Only the First Step in Hong Kong: The ability to prioritise security efforts by ranking your most important hazards according to their monetary values is the main advantage of quantification. Do not overlook the priority step. Create a cyber program for risk management that effectively allocates your resources and provides you with the strongest defense in the shortest amount of time using your quantitative risk analysis predictions and associated metrics.

Spread The Word About Risk Across Your Business

The best results come from properly integrating risk reduction initiatives, cybersecurity audits, and overall management processes across the entire firm. Hence, once you’ve identified which risks are most important, you need to make sure that everyone in your organisation – from top to bottom, across all operating units – is aware of that information. When corporate leaders consistently share risk indicators, risk scenarios, and financial effects, all employees may make more informed daily decisions.

Risk quantification challenges. Quantifying the risk to cybersecurity can be a challenging task. Several organisations lack the resources to adequately carry out the assessment process because the effort can be costly. The method also has significant shortcomings. For instance, you could be tempted to rely on formulas and statistics that have been proven to work, but doing so can lead to erroneous correlations and equivalencies that divert your security efforts. Since the data gathering utilised for quantification is also reliant on past events, it occasionally fails to take into account potential future dangers. 

This rigidity could prevent you from seeing the big picture and lead to unwarranted complacency. A “black swan event” is a statistically rare occurrence with consequences that are more severe than you anticipated. It can happen if you place too much emphasis on predicting likely loss events.

To that aim, keep in mind the importance of qualitative risk analyses and the requirement to recognize emerging threats. Hackers and threat actors are becoming more proficient and shrewd. For security leaders to prevent data breaches and safeguard your company’s data, they must also be creative and forward-thinking.

Improvements To Cyber Risk Quantification

Organisations that are adept at quantifying cyber risk typically share one thing in common: they are aware of how to incorporate their enterprise risk model and risk management with their cyber risk model. Cyber risk quantification frequently fails to yield results because either this integration is insufficient or some fundamental capabilities are lacking. Complex cyber risk estimation is made possible by five interdependent traits. These are listed below.

• Beginning with governance: As your company develops over time, tackling cyber threats requires a consistent, enterprise-wide strategy. This strategy is imposed through governance. Have an operating strategy that supports the objectives and risk tolerance of your organisation. As stated by Rani Jarkas, Finally, establish functional groups to deal with cyber risk and compliance, including setting up oversight committees to ensure that your cybersecurity activities are keeping up with emerging threats and compliance requirements.

• formalise the monitoring of cyber risk: Have a structured, repeatable process to monitor cyber risk data if you want to rely on data-driven decision-making. To ensure that your data is accurate and up to date, you must examine it frequently. Keep track of key performance indicators (KPIs) and build a customised reporting structure for the board of directors or risk committees.

• Classification of Risk: Before you can quantify cyber threats, you must first recognize and describe them. Following that, you can collaborate with stakeholders to develop a priority alignment. Then, it will be simpler for you to create the required internal controls.

Speed Up The Evaluation Procedure

Use a cybersecurity risk framework to reach that level of performance. Accurate risk assessment requires discipline and rigour. The National Institute of Standards and Technology (NIST) is the source of the security frameworks that are most extensively used, while there are many alternative frameworks out there as well. You may create precise, standardised plans for risk management for the entire firm by using a framework. It will also make it possible to automate procedures of risk management.

Accept technology: Software solutions for risk management integrate data and bring various risk management duties together for a more comprehensive, data-driven program. These tools combine quantitative and qualitative data from your evaluations of your entire risk exposure to provide thorough risk assessments and reports.
