Solarwinds may be one of the best-known supply chain attacks; hackers infiltrate software on vendor networks before reaching customers and infecting them directly with malicious code. Presidents have issued executive orders aimed at cybersecurity because information forms the backbone of modern business relationships and processes.
A majority of cyberattacks target software used to manage today's information. This article presents best practices for building secure software, with strategies for identifying and fixing vulnerabilities efficiently and cost-effectively. Furthermore, experts from various fields offer their assistance concerning security efforts.
Secure Software Development: What Does It Mean?
DevSecOps (DEV/SECOPS), also called secure software development, is an approach for creating software that incorporates security at every step in its software development life cycle (SDLC). Building security from conception helps prevent issues later when testing has revealed critical flaws; building it in is vital.
Developers often see security as obstructing creativity and innovation, delaying product launches. Unfortunately, this mindset harms companies since fixing problems during implementation costs six times more than testing. Software engineering has become an integral component of operations.
Organizations that do not prioritize security risk being left behind in competition. How can SDLC ensure security is integrated from its inception? There are two approaches available. First, conduct periodic static and dynamic security tests against documents covering both software security requirements and functional requirements; next, during development, perform risk analyses to detect and mitigate environmental threats.
Organizations looking to develop secure software products must appropriately prepare their employees, processes, and technologies; creating secure software requires an extensive plan. Secure software development is an inclusive, proactive approach that identifies and mitigates security risks at every phase of software development, from design through coding, testing, deployment, and maintenance.
Secure development strives to produce software with resistance against cyber threats while guaranteeing data confidentiality, integrity, and availability - its aim is to build resilient software with guaranteed confidentiality, integrity, and availability that protects privacy while remaining available and usable by all. Secure Software Development Principles:
- Determine potential threats and their vulnerabilities within an application's ecosystem and design by recognizing assets, attack vectors, and weaknesses within its architecture and design.
- Code Security: Employ coding techniques that reduce common vulnerabilities. Input validation, output encoding, and error handling are crucial to avoid attacks such as SQL Injection, Cross-Site Scripting (XSS), buffer overflows, etc.
- Authentication, authorization, and access control: When setting up access controls for an application or software package, use robust authentication methods that verify that only authorized users have access. Utilizing the least privilege principle means only giving out minimal permissions required of each user.
- Put sensitive data behind encrypted walls at rest and in transit by employing encryption keys responsibly and effectively managed.
- Secure communication protocols (SCPs): TLS/SSL are often utilized as secure protocols to transmit data without risking an eavesdropping attack, man-in-the-middle attacks, or data tampering by third parties.
- Conduct regular security testing: Conduct periodic security assessments such as vulnerability analyses and penetration tests to detect and remedy potential vulnerabilities.
- Secure configuration and deployment: Ensure all configuration and deployment processes are secure, including changing default settings to minimize attack surfaces.
- Secure third-party components: Analyzing libraries and third-party components used in developing applications is essential to avoid vulnerabilities through dependencies that could introduce vulnerabilities into an app's structure.
- Real-time security monitoring: Real-time monitoring detects and responds to incidents or anomalies that might compromise security.
- Security awareness training: Provide developers and stakeholders with training on security awareness practices to foster an environment of safety.
- Applications of security patches and updates to address identified vulnerabilities.
- Secure APIs: Verify that APIs exposed by an application have been designed in such a manner as to avoid unauthorized data access or exposure.
By adhering to the principles for secure software development, an organization can produce software that builds trust among users, lowers security risks, and safeguards critical assets while instilling confidence. Secure software development should be undertaken collaboratively by all stakeholders, from developers and testers to managers and executives - it takes all to succeed!
What is a Secure Software Development Policy?
A secure software policy includes guidelines on how an organization can reduce vulnerabilities during software development and how to assess and demonstrate security at each SDLC stage, along with risk mitigation techniques. Your team should understand the rules governing secure software development.
Before going through employee screenings and receiving training on their duties, separation should ensure no single individual holds absolute power in a project, and quality check protocols can also serve as quality checks on employee work performance.
Every successful software development must include an effective policy to protect its software assets by segregating development, test, and operational environments to foster autonomy and remove bias during test administration. Access control allows employees only to view relevant information to their job tasks. At the same time, Version Control records any code modifications over time.
First and foremost, any tech policy that ensures secure software development is to establish rules around programming languages and coding language usage. Developers should then receive training on how to minimize attack pathways.
At the same time, good policies also include instructions for setting up secure repositories for managing code storage purposes. At times it may be recommended and essential for organizations to create policies on secure development.
This applies if their company adheres to SOC 2 Type 2 compliance or ISO 27001 requirements; use either of the ISO 27001 template guide's policy templates as starting points when formulating such an approach to your policy development process.
For Consistency and Best Practice, Use a Secure Software Development Framework
Organizations can reap significant advantages by aligning their practices with NIST's secure software development framework. Groups such as OWASP and SAFEcode offer detailed resources about software security to minimize, mitigate, or even prevent software vulnerabilities. NIST offers four phases as part of its recommended process for developing secure software development.
- Prep organization (PO): Ensure the organization's people, processes, and technology are appropriately prepared to develop secure software on a broad organizational basis and for individual projects.
- Protect software (PS): Limit access and modifications by unauthorized individuals or programs to the components that make up any software program while at the same time minimizing security vulnerabilities.
- Take action to address vulnerabilities: Recognise, fix, and prevent further vulnerabilities within software packages.
Each practice can be defined in this way:
- Practice: An activity, together with its description and identification of its goals and benefits.
- A task is any single or sequence of steps taken towards finishing one particular practice; using examples may illustrate its implementation.
- References: NIST has created this document outlining their four secure software development processes in great detail and mapping them back to crucial tasks.
- Ultimately this section gives an in-depth description of NIST's secure development processes that make up this methodology for software development projects.
Preparing the Organization: Tasks, Practices, and Examples
For organizations to safeguard software development successfully, the first step should be identifying their security requirements internally (Policies, Risk Management Strategies) and externally (Laws and regulations). After this has taken place, teams are assembled with SSDF assigned per team role and tools that accelerate SDLC.
Determining, communicating, and upholding security standard compliance are primary tasks. Training programs, management tools, and other resources must be selected before benchmarks for measuring security standard attainment can be established. Examples may include
- Your developer needs to understand both the coding language and architectural details of the website you are developing; review and revise security needs at least annually, but especially following incidents.
- Assignment of SSDF roles, implementation of periodic reviews, and preparation for potential role changes are my responsibilities as part of my duties as SSDF Project Leader. By creating and specifying categories and tools, I automate toolchain management.
- Audit all actions related to secure developments.
- Determine key performance indicators with automated tools, collect stakeholder feedback, and review and document evidence supporting standards.
Protecting Software: Tasks, Examples, and Practices
Software must be protected until it reaches customers, with special care given to preventing unapproved access and maintaining its integrity. The focus here should be ensuring code remains uncorrupted by outside forces or compromised. The primary use for the storage front entails protecting code under "least privilege," so only authorized users have access to it. Each customer receives a complimentary release with details on integrity checks and components.
- Attainable code should only be stored in an archive with restricted access and secure digital vaulting capabilities; using version control systems as an excellent way of tracking all code changes and signing with reliable certificate authorities before release software releases are essential, as is posting cryptographic hashes for software releases.
What to Do When Producing Secure Software? Tasks, Examples, and Practices?
Before third-party software can be evaluated, it must first meet security standards and requirements. Developers then implement best practices in code writing to improve product security; manual and automated analysis methods detect vulnerabilities; default security features provide protection out-of-the-box; trusted components may even be utilized during production.
Tasks associated with cybersecurity encompass creating trusted component lists, assessing risks using threat models, and reviewing external security requirements. In addition to designing and conducting vulnerability tests on all vulnerabilities before any results can be documented and issues rectified, designing and conducting vulnerability tests must also be performed before documenting results or rectifying issues.
Setting secure defaults can be time-consuming and unnecessary for some people. They must fit with existing security options on your platform before being explained to administrators for approval.
- It may include providing training to developers on best construction practices and risk assessments, reviewing current designs as well as previous vulnerability reports to ensure security is addressed appropriately;
- Create policies to oversee third-party risk and include security in contracts you sign with third parties while limiting unsafe building functions to only zones requiring safe codes of construction and development.
- It is best practice always to use the most up-to-date valid version of compiler tool software when developing any project requiring compilation tools.
- Utilizing peer reviews, static/dynamic analyses, and penetration tests to detect software vulnerabilities while documenting our findings and learnings and creating a trusted component repository.
- Verify that security settings meet acceptable levels, and document how administrators must use their authority.
Practices, Tasks, and Examples to Respond to Vulnerabilities
Security experts occupy more than just finding weaknesses; their tasks also encompass remediation - correcting vulnerabilities and collecting data that prevent future attacks. Once vulnerabilities have been discovered and confirmed, remediation should begin immediately to limit threat actors' attack window, and understanding their source can assist in avoiding similar incidents in the future.
This final stage involves gathering customer information and testing code for undiscovered vulnerabilities, quickly responding to these vulnerabilities through rapid vulnerability response plans, and remediating identified ones as quickly as possible.
Root causes must also be closely examined over time to recognize patterns and address similar problems found elsewhere in software packages. Finally, SDLC must be regularly revised to prevent similar issues with future releases.
- It may include Chaudiere producing a Vulnerability Report and Response Plan
- Automating code analysis to locate vulnerabilities.
- Assessing each vulnerability's severity level before prioritizing remediation activities and prioritization for priority remediation projects. And to incorporate an innovative detection system. * (*). - SSDF will be updated accordingly in the future.
Why Are Developers Skipping Security Steps?
We've listed some of the main reasons software developers skip security during custom software development service.

Time and Resources Lack
Under pressure to meet tight deadlines, developers may overlook security measures. Recent surveys reveal that 67% of developers don't address security vulnerabilities in their code due to deadline pressures. Business leaders who understand and recognize the significance of secure software will invest extra resources and time in security tools.
Developers only require minutes to write the code for a simple web form; for longer forms, however, additional assistance may be required to prevent cross-site scripting attacks. Under tight time constraints, it can be nearly impossible for developers to create forms incorporating protection routines within one hour, prompting them to prioritize other elements over this step.
Insufficient Education
Understand that different developers may approach development differently and prioritize security differently during development stages. Your developers may not place enough importance on this aspect during this process.
Security and Development Silos
Some business leaders mistakenly believe that software security must only be handled by specialists. However this might work in certain instances, but this approach does not always provide adequate software protection.
Due to this misperception, many organizations maintain separate teams of cybersecurity professionals from developers; therefore, these individuals do not directly communicate. Security vulnerabilities may take months, even weeks, to be identified, compromising system security while slowing development efforts.
Though separate security teams and development teams exist, it is crucial that, when possible, these two groups collaborate closely to promote an open dialogue. Prioritizing security shouldn't be our number one concern. Recent survey results demonstrate how few companies prioritize secure software development as a top priority. Eight-sixths of developers surveyed stated security was not top of mind during software creation - an alarming statistic!
Best Developer Security Practices
We're going to discuss the best security practices for developers.
Software Security Should Be a Priority From the Start
Your team and you have already discussed the significance of including security in software development processes. Adopting a secure software lifecycle is of utmost importance, as ensuring security at each step in a project's lifespan - planning, design, and development, as well as bug fixing or maintenance, should always include security checks as they unfold.
Assessing security should become part of every decision-making process for projects of every sort: planning, design, and bug fixes should always include assessments in their process - something not all projects do! SDLC security can be significantly increased through simple actions taken by developers themselves.
Encouraging them to use pre-commit hooks may prove immensely effective at protecting secrets from being committed into repository source code and saving lives. Make a collaborative environment by improving your organization's culture and encouraging cross-team cooperation. Code written by satisfied developers who put safety first will result in higher levels of security being considered when creating code.
Determining Project Security Requirements
Before embarking on any development work, any security gaps and weaknesses must be identified and eliminated. Please use these helpful hints as guidance.
- Software with multiple cores is designed to respond to unknown or unpredictable interactions among threads and processes, including unexpected interactions that arise among them.
- Multiple core systems also strengthen resistance against unintentional or intentional failures - cybercriminals often utilize them to flood systems with fake queries that overwhelm their systems and result in their collapse.
- Create a hierarchy for rights (project roles) so you can grant access based on each user's role while restricting the behavior and operations of individual processes to prevent hackers from damaging or disrupting the system.
Identification of Potential Security Threats
Identifying any security flaws within the tools utilized is crucial before your development team begins to work on any projects. Take a proactive stance in writing code, unit testing every area that needs examination, and reviewing each change made to detect new vulnerabilities in their codebase.
Standards and Guidelines for Secure Coding
Utilizing secure coding should be imperative for every organization, depending on its project requirements and goals. Securing data like financial and personal records should always be on your mind. Data must be protected from files, databases, cookies, and sessions during storage and transit.
Encryption software protects these assets, but malicious individuals could compromise these channels to cause breaches in data protection. When creating secure coding standards, they must conform to industry norms. Standards encourage organizations to adopt more efficient design principles, making your security standards options all the easier to determine.
Here are your best choices when it comes to security standards.
OWASP SAMM
OWASP stands for open web application security project, and this standard establishes requirements and processes for the security testing of web apps. The OWASP security assessment and management model (SAMM) provides organizations with a tool for tailoring their security operations according to risk profiles.
Nist (National Institute of Standards and Technology Ssdf)
The NIST SSDF provides guidelines to assist software development organizations, like OWASP, with secure software development practices. Below, the NIST Secure Software Development Framework organizes software development into four distinct areas.
- Organize your organization: Before initiating any technology-intensive development work, ensure all technologies, processes, and personnel have been prepared in advance for safe development by both team members and administrators alike.
- Protect software components from unauthorized access: All software components should be secured against unauthorized access as early as possible in the development cycle.
- Fully secured solutions refer to software developed with minimal security vulnerabilities. They include solving vulnerabilities by detecting and correcting potential security flaws to reduce future releases containing them.
Upgrade Frameworks and Libraries
Organizations using software development techniques need to use libraries and frameworks with long histories, with fewer vulnerabilities due to being around for longer. When selecting such frameworks for use when developing secure software applications.
Use secure libraries to reduce your attack surface and enhance software security, with open-source components helping identify bugs early. Developers should conduct extensive research before including any framework in their system. An actual person should review each new library before being added; additionally, using a central registry for software components gives more control over third-party apps.
Conducted Security Awareness Training
Your software team should receive training on the most pressing risks to software creation. Developers can avoid creating code vulnerable to cyber criminals by understanding how they operate. Hold regular team meetings so your employees can exchange information and learn secure development techniques to create code that resists cyber attacks.
Safe Access To Databases
Databases are one of the software's most essential and precious components, which must be secured and configured correctly to protect them adequately and keep data leakage and unauthorized access at bay.
You should ensure your system does not contain any loopholes that allow accessing personal or sensitive data without authorization and avoid potential security breaches or information leakage.
Use Digital User Identification
Use digital identities to restrict access only to specific users and developers. Your repository could be vulnerable to security breaches if users gain unrestricted access through insecure links. Implement and regularly evaluate a digital identity system to guarantee access for everyone involved.
In All Areas, Handle Errors and Exceptions
Maintaining an effective system requires managing exceptions and errors effectively, including those caused by unpredictable situations that arise unexpectedly, and creating processes that prevent the entire system from collapsing.
To this end, exception management strategies allow systems administrators to control exceptions that arise by setting response options within the software that respond automatically in these instances while creating safeguards to keep failing systems from failing altogether.
Monitor Security Information
Logging security information is key for keeping track of any odd behavior from solutions, helping detect security breaches, and providing valuable insight into system activity and behavior - giving you enough data on its operation to address problems before they become data breaches.
Conclusion
Manufacturing secure software solutions is an industry-wide responsibility that demands constant vigilance to protect sensitive data and infrastructure and employee and overall operational safety. Security must become part of industrial software solutions as their reliance grows in this rapidly expanding sector.
Building secure software requires considering multiple aspects that meet the challenges and needs of industrial environments. Industry leaders who implement adequate security measures can increase trust with stakeholders while safeguarding them against cyber threats and protecting critical systems from disruptions.
Risk assessments must be carried out to accurately pinpoint potential vulnerabilities, helping create a security strategy tailored to industrial applications' unique characteristics. When developing resilient software, secure coding techniques, communication protocols, and authentication mechanisms must be employed along with sophisticated safeguards against data theft or compromise.
Security testing is crucial to identify and remediate security vulnerabilities before being exploited by potential adversaries. At the same time, compliance audits ensure maintaining an effective cybersecurity posture.
Industrial firms need to adopt an active culture of security, including training and awareness programs for staff and creating security awareness throughout the organization.
