Continuous Threat Modeling – Benefits and Challenges

The threat modeling method that seeks to discover the threat, communicate with it, and eventually identify the various threats and their mitigations within the network. A threat model can be described as a logical “model” of the information available that can influence the security of the app. In essence, a threat model is a representation of the application or network that is focused upon its safety. In general this method of modeling is useful in software, applications networks, distributed systems, IoT devices, and even business processes.

The most common threat models would comprise the following elements:

The description for the object being or will be modelled
General assumptions that need to be challenged or examined as the threat landscape changes
A list of possible security threats to your system.
The following list of actions can be carried out for threat reduction
The process of validating the model in conjunction with risks and the confirmation of the effectiveness of the actions which have been implemented.

In terms of the fundamentals, threat modeling is the process of analysing the data, organizing, and capturing all of the above information. If we apply this process in software applications, it allows professionals to make educated decisions about security threats within the software. Alongside the creation of the risk model, threat modeling permits security experts to create a list of security enhancements that could improve the software in terms of its concept layout, safety, and general needs.

The Goals

Threat modeling seeks to enhance the security of a application or system by identifying threats specific to the system and then establishing the process to implement the appropriate countermeasures to prevent or mitigate these types of threats from occurring.

Threat Modeling Benefits

Since the threat landscape changes constantly threats models require constant refinement and tweaking when an organization wants to be ready for the possibility of attacks and data breach. Hackers are constantly developing new methods of infiltrating the systems they attack and take advantage of vulnerabilities and constant threats modeling upgrades can assist organizations protect themselves. In this regard below are the most frequently-used benefits of continuous threat modeling

Automatically updating Risk Exposure

The ever-changing threat landscape frequently introduces new targets for attacks and opens up security risks in applications, systems cloud-based as well as on-premise deployment systems IoT technology wireless networks, embedded networks computing endpoints, and so on. By utilizing constant threat modeling, businesses are able to stay abreast of the latest threats. The changes can be tracked in real time and assist in determining the possibility of new attack targets were discovered, giving current and accurate information about the risk of exposure.

Always up-to-date Risk Profile

A complete and regularly updated risk profile is a great way to highlight risk vulnerability and allow security professionals to pinpoint the sources of threat. The information on the risk profile could be used as a great base for security control audits as well as for the implementation of more secure programming methods. Test for target and aid in establishing a more effective risk mitigation strategy. Risk profiles can help when it comes to mergers, acquisitions and third party reviews. The profile allows for rapid and accurate information on critical risks as well as providing accuracy, consistency and accuracy.

Consistent Security Policy Across the Board and a reduction in attack surfaces

The existence of a complete database of threat information where threat information is properly classified and organized by risks and security requirements and accompanied by security code snippets that permit mitigation, can be a huge help in helping to improve overall security coherence. This can also help minimize the scope of the security risk across the whole system. To keep this data relevant to respiratory health continual threat analysis is required.

Eliminating All Risks across the System of the Enterprise

An organized inventory of data in which every possible threat is identified and covers each IT environment element of an organization will allow security professionals to quickly spot and mitigate affected areas that may have been affected by new threats, or even internal initiatives. Furthermore, continual threat modeling could prove beneficial in the data center model that can help enterprises implement mitigation security measures based on security needs.

Aligning the Mitigation Strategy to the Budget

Threat mitigation typically involves the requirement for code modifications such as regression and functional testing as well as security analyses, and many more costs for custom-designed solutions. Threat modeling might also be capable of helping calculate mitigation costs, which allows organizations to coordinate their mitigation strategies with budget allocation.

Security is Measurable

If an organization is constantly implementing risk modeling it is capable of assessing whether its security programs. When you release security trends, studying the security situation in identifying important vulnerable entry points becomes simpler. Additionally the vulnerability comparison documents help security professionals compare particular vulnerabilities among applications or system initiatives.

Leveraging Threat Intelligence in Real-Time

An accurate and current threat model can also enable security professionals to integrate useful information on attacks from trusted sources such as those of the Web Hacking Incident Database (WHID) and the National Vulnerability Database (NVD). These databases offer real-time details on how other companies were affected and impacted through the hack, with a focus specifically on the impact on technology. The use of this data will provide actual-world examples for security personnel, who are able to assess the potential risks of threats and attacks more precisely.

Threat Modeling Challenges

Although threat modeling is generally thought of as to be a “must” for any organization and business looking to stay current with their security procedures however, this approach could create some issues for security teams and whole organisations alike. Below, we’ll look at the most popular methods.

Threat Modeling Oversaturation in Threat Modeling

There are a variety of methods for threat modeling that security teams can employ and this can lead to confusion, particularly when there isn’t a security expert with experience within a particular team. This issue can make it difficult to assess different methods and pick the best one to meet the security needs of the organization. Additionally, making the wrong choice could cause inadequate investment and even undermine the capabilities of mitigation. This can result in an increase in threat exposure and exploit threats. There are instances where security personnel struggle with verifying threats and their models. Most of the time, they are unable to reduce the risks effectively in the network, which leaves them vulnerable to the risk of intrusion.

Unrecognized Entry Points, Trust Boundaries

If a company decides to use cloud-based services, the company will have to be aware that there are many not recognized entry points. They could be APIs that are publicly available and services, management planes and much other. This means that there are many ways to be accessible via the internet, including API gateways which allow criminals to invoke accounts across. For example, Lambda functions can be activated through invoke IAM permissions, as well as S3 buckets, which allow attackers to add harmful events straight into SQS queue.

Applications Scaled-up

Threat modeling is easier in the case of monolithic applications, where there’s just a tiny amount of dependence and dependence on external entities. Also, your computing environment is accessible as a consumable view. The issue is that the apps of today are complex monolithic systems that are often scalable, cloud-migrated, and frequently the app team is in charge of taking care of the fill-stack. This is a complete departure from previous deployment models which IT teams were responsible for managing the physical servers of the application and the entire network infrastructure. The threat model must be able to handle the increased responsibility for the infrastructure, expansion of topologies, scope changes as well as other dangers, which can be difficult to manage.

Problems with Threat Breakdown and Risk Predictions for Actual Risk

The high-level threat can be difficult to recognize, and so is breaking them down into smaller threats to reduce them effectively. Additionally, identifying the conditions that can cause these threats can be a bit difficult. However, having this knowledge is essential to gain a better understanding of the probability of a serious threat as well as these insights will increase the effectiveness of risk mitigation. Comprehensive threat models help with the mitigation of risk and provide security professionals the right methods and tools to conduct thorough security tests to accurately anticipate possible attack scenarios.

The Bottom Line

Since hackers are always developing, using ever more complex techniques of infiltration, they uncover new vulnerabilities that are being discovered on the application layer. Continuous threat modeling is designed to offer an efficient and effective method to decrease the chance of compromise in a company’s security strategy. In the majority of instances, continuous modeling will provide the needed information and insight to develop an effective security strategy comprised of effective mitigation and prevention strategies.

In the same way threat modeling allows businesses to evaluate their security and build an entire security portfolio which can assist security personnel make the best decisions when there is a risk of infiltration.

On the other hand, threat modeling is still a source of number of challenges that can lead to false positives in the detection of threat risks and their remediation. But, ongoing as well as automated threat modelling could be an essential element in the field of organizational cybersecurity since it remains an extremely efficient ways to analyze and mitigate security vulnerabilities.
