In this blog, we’ll walk you through some essential practices to follow for secure software development. Let’s dive in and ensure your software stays strong against potential threats!

Common Security Threats in Software Development

When developing software, there are several security threats that developers must watch out for. These threats can pop up at any stage—during development, launch, or maintenance—so keeping security in mind from the get-go is crucial.

Cybercriminals are always on the lookout for vulnerabilities to exploit, and understanding these common security risks can help you stay one step ahead.

Here are some of the most common security risks in software development:

• Data Breaches: A data breach happens when hackers gain unauthorized access to sensitive information, like customer records or financial details. This often occurs due to weak passwords, outdated software, or the absence of encryption.
• Insecure APIs: APIs are used to connect different systems, but if not properly secured, they can become gateways for hackers to access sensitive data or disrupt the system.
• SQL Injections: This attack involves injecting malicious code into a database query, allowing hackers to manipulate databases and steal sensitive information.
• Cross-Site Scripting (XSS): In XSS attacks, hackers inject malicious code into websites or web applications, usually through forms or URLs, to gain control or steal data.
• Malware: Malware refers to harmful software designed to damage systems or steal data. It can come from emails, websites, or downloads, and examples include viruses, ransomware, and spyware.
• Phishing Attacks: In phishing, hackers send fraudulent emails pretending to be from trustworthy sources to trick users into revealing sensitive information or installing malware.
• Unpatched Vulnerabilities: Software with unpatched vulnerabilities—known security flaws that haven’t been fixed—can be exploited by hackers to gain unauthorized access to systems, as seen in high-profile attacks like the Equifax breach.
• Weak Password Policies: Poor password policies can lead to brute force attacks, where hackers attempt to guess passwords by trying all possible combinations until they find the right one.
• Insufficient Logging: Logging helps track system activities and detect unusual behavior. Without proper logging, hackers can operate unnoticed for longer periods, increasing the damage.
• Unauthorized Access: This happens when hackers exploit software vulnerabilities or steal credentials to gain access to sensitive systems and data without permission.

Secure Software Development Practices to Consider

Now that you know the risks, let’s talk about the best practices to ensure secure software development. Following these practices can help you build robust software and protect it from potential threats.

1. Prioritize Software Security From The Start

Security isn’t something to think about later; it should be a priority from the very beginning of the software development lifecycle. This means integrating secure practices into every stage, from planning and designing to bug fixing, maintenance, and project completion.

Even small actions can have a significant impact on your software’s security. For example, using pre-commit hooks can act as security seatbelts, ensuring sensitive information, like passwords or API keys, isn’t committed to source code repositories. Additionally, AI tools are now making it easier to automate security checks during development. Using AI in software development can ease the work of software developers.

Moreover, fostering a positive team culture and promoting collaboration across departments can also encourage developers to take security more seriously. Happy developers tend to write more secure code, so don’t overlook team satisfaction as a contributing factor to your project’s security.

Working with experienced software development companies can also help you ensure that your project follows industry-standard security protocols from the start.

2. Define Your Project’s Security Requirements

Before you start writing code, it’s essential to identify any potential security gaps and define your security requirements. One way to do this is by employing multi-core secure software design, which accounts for unknown interactions between processes and threads.

Your system also needs to be resistant to intentional and unintentional failures. For example, attackers often flood systems with fake queries to overload them and make them unmanageable. Planning for these scenarios is key to maintaining system integrity.

Another crucial aspect is setting a hierarchy of user rights (project roles), where each person only has access to the parts of the system they need. Limiting access reduces the potential damage if a breach occurs.

Finally, setting constraints on process behavior ensures that even if hackers gain limited access, they won’t be able to manipulate the entire system.

3. Check for Potential Security Threats

Work closely with your team to identify any potential security threats associated with the tools and technologies you’re using. This process should take place before any development starts.

Adopting a defensive mindset while writing code is critical. Unit testing should be performed regularly to check for vulnerabilities, and each code update should be reviewed to ensure no new security risks are introduced.

4. Establish Secure Coding Guidelines and Standards

Having a set of secure coding guidelines is essential for any development project. These guidelines should focus on protecting data, whether it’s in transit or at rest. Stay up to date on the latest software development trends to create and enforce guidelines effectively.

Encrypting all types of data, such as cookies, session information, file storage, and database storage, is essential. Also, remember that your team’s communication channels are attractive targets for cybercriminals and should be secured to prevent data breaches.

You don’t have to start from scratch when establishing secure coding standards. There are well-known industry standards to guide you:

OWASP (Open Web Application Security Project): Provides a list of secure development requirements and offers a strong foundation for testing web application security.

OWASP SAMM (Software Assurance Maturity Model): A tool to help organizations adapt security operations to fit their risk profile.

NIST SSDF (Secure Software Development Framework): This framework, created by the National Institute of Standards and Technology, provides a set of secure development rules based on proven best practices. NIST SSDF breaks down the software development lifecycle into four categories:

• Preparing the Organization: Ensuring that technologies, processes, and team members are ready for secure development at both team and organizational levels.
• Protecting Software: Preventing unauthorized access and tampering with software components.
• Developing Fully Secured Solutions: Releasing software with minimal security vulnerabilities.
• Responding to Vulnerabilities: Addressing security flaws in software and preventing them from recurring in future releases.

5. Use Trusted Frameworks and Libraries

Many organizations rely on various frameworks and libraries during software development. However, not all of them are equally secure. It’s important to choose well-established, well-maintained, and trusted frameworks to minimize the chance of security vulnerabilities.

Using open-source components can be particularly beneficial because they allow for early bug detection. Employing secure libraries also helps limit your system’s attack surface.

Make sure to carefully check the reputation of any framework or library before incorporating it into your system. Ideally, submit each new library addition for human approval. A software component registry that is well-maintained and enforced can help you manage all third-party tools and libraries in use.

Partnering with trusted software development agencies ensures that the right frameworks and libraries are used, minimizing the risk of vulnerabilities.

6. Provide Security Awareness Training

Your development team must be well-versed in the security challenges they may face during the software development process. It’s important to educate them on the common security attacks, especially those that are relevant to your organization’s domain. When developers understand how hackers operate, they are more likely to avoid insecure coding practices that can be easily exploited.

Frequent security training sessions are a great way to keep your team informed. Organizing regular meetings where developers can discuss secure development techniques will encourage better collaboration and help them write code that can resist cyberattacks.

7. Secure Access to Databases

Databases are one of the most critical components of any software system, housing sensitive data that must be protected at all costs. Ensuring that no data leaks or unauthorized access occurs through overlooked vulnerabilities is crucial. This means properly configuring databases and continuously monitoring for potential cracks in the system.

8. Implement Digital User Identity for Controlled Access

Digital user identity systems allow you to control who has access to different parts of your software. This is important for restricting access based on each user’s or developer’s specific role, ensuring they only have access to the tools and data they need to do their job.

For instance, if your GitHub repository has unrestricted access, it’s like leaving the door wide open for potential security breaches. Implementing a digital user identity mechanism ensures that only authorized individuals can access sensitive areas, and it’s important to review these access permissions regularly to maintain security.

9. Manage Errors and Exceptions Across the System

Proper error and exception handling is essential to keep your system running smoothly. It determines how your software will react when it encounters unexpected situations and helps prevent it from crashing. By setting up a reliable system to handle these errors, you can ensure that even in the face of unpredictability, your software remains secure and stable.

10. Monitor Security Data

Logging security-related information is critical for keeping track of any unusual activity within your software. Monitoring security logs will not only help detect potential security incidents early but also provide valuable insights into the system’s behavior. By identifying suspicious patterns, you can address vulnerabilities before they escalate into serious data breaches.
