Now that we have already studied the principles, policies and standards of cybersecurity systems, we move forward to Risk Analysis in cybersecurity. With increasing number of attacks and crimes against computer systems and networks, there is also an urgent need for firms to perform regular Risk Analysis of their cybersecurity systems for better coverage and long-term solutions to cybercrimes.
Introduction to Risk Analysis in Cybersecurity
Risk Analysis in cybersecurity means the assessment and review of risks corresponding to the specific incidents of cybercrimes and cyberattacks. Risks Analysis becomes very important when organizations become prone to cyberattacks and targeting from hackers.
Firms with these problems have to analyze risks and threats and create premature cybersecurity strategies to mitigate those risks in future. This not only makes the firm difficult to target, but also causes a rise in cybersecurity levels in the ecosystem overall.
Risks are a regular occurrence in many IT firms and tech companies. Risk Analysis should be conducted on a regular basis in both small and large firms. A very detailed and thorough Risk Analysis helps to minimize the future risk occurrence and incidents of cybercrimes.
How to Analyze Risk in Cybersecurity?
The key steps to analyze risk and mitigate any probability of cyberattacks and crimes is given as follows −
- Identification of Assets and Resources
- Detection and Identification of threats and their source
- Reviewing the level of vulnerability of critical systems
- Modeling the worst case scenarios
- Assessment of Risk involved in the incident
- Risk Mitigation
- Recovery plan from potential risk
Types of Risk Analysis in Cybersecurity
There are many types of Risk Analysis techniques which are used worldwide. Some of the most popular and in-demand risk analysis strategies are given in the following section −
- Qualitative Risk Analysis
- Quantitative Risk Analysis
- Hybrid Risk Analysis
- Threat-based Risk Analysis
- Incident-Response Analysis
1. Qualitative Risk Analysis
This type of risk analysis is purely based on the subjectivity of the matter as well as the past experiences of incidents and their mitigation. It is a very fast approach, and it is easily implemented. The only downside to this approach is that it can be influenced and affected by personal bias and prejudices.
The strategies to conduct a qualitative risk analysis may include the following points −
- Delphi Technique of Risk Analysis
- Risk Matrices
- Consensus Algorithms
2. Quantitative Risk Analysis
This type of risk analysis is purely based on logic and calculations. It is used to predict outcomes based on probabilistic events and likelihood of different scenarios. The mathematics involved can be very complex and time consuming, which makes this method a bit difficult and lengthy.
The strategies involved in Quantitative Risk analysis may include the following points as well −
- Probability Analysis
- Loss Modeling
- Cost-Benefit Analysis
- Risk Tolerance Analysis
3. Hybrid Risk Analysis
This type of risk analysis includes strategies which are a combination of both Quality based and Quantity based risk analysis. This helps to get a comprehensive view of the risks involved from both the perspectives.
The techniques involved in this type of risk analysis include the following −
- Risk Matrices
- Risk Heatmaps
- Risk Scoring
4. Threat-based Risk Analysis
Several threats are posed while analyzing cybersecurity systems. Many attacks can be predicted based on threat evaluation and assessment. This approach involves gaining knowledge about specific threats and planning the strategy based on these specific requests.
The strategies included in this approach of risk analysis include the following −
- OWASP (Open Web Application Security Project)
- STRIDE (Spoofing, Tampering, Repudiation, Information Disclosure, DoS and Elevation of Privilige)
- PASTA (Process for Attack Simulation and Threat Analysis)
5. Incident-Response Analysis
Several incidents in the near past can also be utilized to conduct a thorough analysis of the risk associated with cybersecurity systems. These can include a single type of attack or multiple attacks with interrelated areas of cybersecurity systems.
These attacks give rise to a very detailed analysis of the risk involved, and urge the firm to take immediate steps to mitigate any future threats to the cybersecurity systems of the firm. The strategies involved in incident response analysis include the following −
- Wargaming
- Tabletop Exercises
- Simulation Modeling
Benefits of Risk Analysis in Cybersecurity
Risk Analysis in cybersecurity ecosystem is a very crucial aspect, and major firms must conduct Risk Analysis on a regular basis. The benefits of risk analysis in cybersecurity can be understood more clearly by identifying the following points −
1. Decision Making
Risk Analysis helps the firm in quick and efficient decision making during or after a cyberattack. This also helps the firms to prioritize their security investments and manage recourse allocation properly.
2. Risk Management
Risk Analysis in cybersecurity helps organizations to identify and address critical loopholes and fallacies in their systems. By analyzing these risks, the organization can include effective preventive strategies to reduce the probability of future attacks and decrease the exposure of their cybersecurity system to potential threats.
3. Trust Building
With improved and effective cybersecurity solutions in hand, thanks to various risk analysis schemes, the company can build trust and gain confidence of their customer base. This not only increases their business, but affects the overall reputation of the firm as well.
4. Cost Effectiveness
Different strategies related to Risk Analysis help in reducing the overall budget allocation to Cybersecurity solutions in a company. If implemented correctly, the firm can predict and solve potential problems as per the analysis and assessments, and manage future plans. This also helps the firm to allocate resources in critical areas and avoid unnecessary overall costs.
