Risk Mitigation in Software Engineering

Developing software while preserving its embedded security can feel like an impossible task. As you update your product, you’re potentially adding new vulnerabilities. As part of the risk management process in software engineering, you need to work with cybersecurity professionals throughout the software development life cycle (SDLC) to create a mature security profile.

What Is Risk Management in Software Engineering?

Traditional risk management refers to identifying and preventing any risks faced by a company that could cause financial losses. In software engineering, risk management refers to any threats that could cause a project to fail before its completion.

A risk management plan looks at the process of software development and the wide variety of risks that can occur before the software project is ready for its intended function. The details of the application will change frequently throughout the development process, and any issues that could threaten the outcome of the project should be cataloged as risks.

What Is the Purpose of Risk Management in Software Engineering?

New programs are untested and uncharted, which means they’re vulnerable to risk throughout the development process. At any given point hackers could access your work in progress, perhaps to steal your intellectual property or collect information for future attacks; or the project itself may suffer from insufficient funding or a lack of staff.

So it’s not enough to examine risks for the finished product. You must look carefully at what risks exist for the entire development period, start to finish.

What Are the Five Risk Management Processes? How Can They Be Applied to Software Engineering?

1. 1.Identify. Probe for all possible risks, and continue to look for new risk factors as the project moves forward.
2. 2.Analyze. Examine the likelihood of the identified risks, the source of the risk, and the level of loss that would be inflicted if the threat should occur. Be prepared for your initial analysis to change over time.
3. 3.Evaluate. Determine what tactics can best minimize or eliminate each risk based on your previous analysis. This process allows you to create a risk management strategy that can be adapted as your software development project moves forward.
4. 4.Treat. Put preventative measures into action. The treatment step will shift and change as your project changes and encounters new risks.
5. 5.Monitor. Monitor the potential risk throughout the lifecycle of the project. The project manager should be involved in every step of the decision-making process and should be kept apprised of any new potential risks that may arise.

What’s the Difference Between Risk Management and Risk Mitigation in SDLC?

Risk mitigation is a part of risk management and is one of several strategies you can use to prevent damage from risk. Mitigation specifically refers to reducing the effects of a risk once it has occurred. Mitigation recognizes that some risk is inevitable and seeks to prepare rather than prevent.

Risk mitigation in software development parallels the process used by traditional businesses. As outlined by the Open Web Application Security Project (OWASP), the Software Assurance Maturity Model (SAMM) focuses on assessing, formulating, and implementing a software security strategy that integrates into the SDLC. Regardless of development methodology, you can follow a risk management process that allows you to protect your software throughout each stage of development.

How Does SAMM Approach Risk Mitigation?

OWASP embeds risk mitigation and response throughout the development cycle. Each group within the organization retains responsibility at different points in time. OWASP breaks down software development into four basic business functions, each of which divides into three practices:

1. The Governance Function

Governance focuses on business outcomes and deliverables such as strategy, metrics, policy, compliance, education, and guidance.

The Strategy & Metrics (SM) Practice

Creates measurable security goals to mitigate the business risks inherent in data events.

The Policy and Compliance (PC) Practice

Establishes written standards that meet legal and regulatory requirements, including audits that provide the necessary assurance.

The Education & Guidance (EG) Practice

Increases workforce access to information so that they can identify and mitigate security risks more effectively.

2. The Construction Function

Construction focuses on defining goals and creating software within projects. The project management team should be included as part of these steps.

The Threat Assessment (TA) Practice

Focuses on risk identification and risk analysis, looking at both the impact an attack may have and the probability of occurrence.

The Security Requirements (SR) Practice

Analyzes high-level security requirements based on how an organization intends to use the software. Reviews new risks and how to mitigate them as the software matures, considering interactions with suppliers and adhering to audit standards as required in Service Level Agreements (SLAs).

The Security Architecture (SA) Practice

Builds in security by default, focusing on explicitly designing software with security functionality in mind.

3. The Verification Function

Verification relates to continuously testing, reviewing, and evaluating software for new risks.

The Design Review (DR) Practice

Assesses design and architecture to detect and address issues early in the process, aiming to locate security issues before they become costly.

The Implementation Review (IR) Practice

Reviews source code and configurations for security vulnerabilities. Early stages may use simple checklists; mature organizations often use automation for greater coverage.

The Security Testing (ST) Practice

Reviews security in the runtime environment, including traditional penetration testing for high-level test cases or review for other misconfigurations.

4. The Operations Function

Operations relates to all activities that are part of the software’s release, such as shipping, deployment, hosting, and operation in the runtime environment.

The Issue Management (IM) Practice

Creates processes for handling issue reports and operational incidents by assigning roles, organizing a formal incident response process, and tracking issues. Requires communication between all stakeholders.

The Environment Hardening (EH) Practice

Focuses on assuring that the underlying infrastructure maintains the software’s security posture. To assure manageable deployment of security patches, keep the development team’s information and find ways to review the operating environment.

The Operations Enablement (OE) Practice

Focuses on risk monitoring to assure that project teams communicate risks to users and operators. Create documentation with details that users and operators need, and share those with each release.

Why Embedding Security Within Software Development Matters

As more companies use Software-as-a-Service platforms to enable their businesses, they also recognize that vendors are one of the most significant data breach risks. With the glut of SaaS platforms on the market, a SaaS vendor can stand above the competition if it makes security a primary differentiator.

Most SaaS platforms recognize this, and many may say they’re secure — but the vendor data environments remain murky. You need a project manager who focuses on project risk management and mitigation to assure that you’re genuinely securing your product.

How ZenGRC Enables Risk Management During SDLC

The OWASP SAMM requires documentation from myriad stakeholders throughout the development cycle. This amount of data can’t be held on a shared drive or tracked in a spreadsheet. If you want scalability, you need an automated process for tracking and documenting your security reviews.

ZenGRC allows you to prioritize tasks so that everyone knows what to do and when to do it. With workflow tagging, you can assign tasks to the individuals in your organization responsible for the activities involved in risk assessment, risk analysis, and risk mitigation. With audit trail capabilities, you can document remediation activities to prove that you maintained data confidentiality, integrity, and availability as required by law.
