Custom Software Development Best Practices for Elevated Security
The custom software development and cyber security are two most sophisticated topics. If you are not qualified enough you might not able to comprehend these two subjects. Therefore I will try to explain it in a very simple and less technical manner. When a business decides to build a customized software solutions such as a customer portal, intranet application, customer relationship management tools, mobile applications, payment portals or interactive self-service channels for their customers, the very first step is to understand the basics of the software security. The first and most important step is to draw a security requirement outline.
It doesn’t matter how well you understand software development or cyber security, you just need to understand the basic working of the application and data management. You can engage a professional software developer either form your team or from your outsourcing partner’s team. Just sit with them and ask them what data will be collected from the users, what will be stored within the software application and what data will be transmitted or fetched from other software solutions or databases. This will help you understand the criticality of various data types. For example the personal identification information and the financial information requires the highest security possible.

Once you have all these data types you can now begin with the development of the application and at the completion you will have to sit with the team again to see if the following crucial cyber security best practices are followed correctly or not. Early security planning and identification of compliance is crucial. Moreover different industries also have different security compliance, required by relevant government authorities. Identifying these requirements early on will not only help you make your custom software solutions more secure but it will also save you time and cost of redesigning later. Following these best practices will also help you eliminating flaws and vulnerabilities from your tailored software solutions:
Use Secure Coding Techniques
The custom software development is a technique of building software applications and solutions form ground up. Most of the times these software tools are built using various different software stacks and frameworks. This means that the software development team will have to do a lot of coding and programing to achieve the desired functionalities. Writing secure code and following secure coding methods is crucial to ensure the ultimate security of the customized software. When the security best practices are implemented from the very beginning, it results in better and strong security of the application. For example:
- Input Validation: All inputs should be validated before sending them to the system or database. This practice will help you minimizing the chances of SQL injections and cross-site scripting. These two are most common threats for software applications.
- Data Sanitization: This one is also relevant to the above point, but it will help you elevating the security. As the name suggest the data sanitization means ensuring any data or command entering to the software is sanitized, hence ensuring no code injection or unauthorized access.
It is crucial to ensure all team members are well-versed with the above best practices and methodologies. Furthermore businesses should also check and review the code at every milestone or at completion of every module. Moreover once your customized application is complete, you should conduct a thorough security analysis.

Implement Strict Access Control and User Identification
When businesses opt for custom software development they tend to have requirements from a particular user group or department. This means that there could be so many different users who will be operating your customized software application. The access control is simply a mechanisms to manage who can access which part of your software application. The access control will dictate the policy to grant various accesses to different features and functionalities. You should ask your custom software development team to build control mechanisms and features which allow you to define multiple job roles with ability to give them access to different parts of the software.
The role-based access control features will allow businesses to create multiple job roles with different levels of access. For example, the system administration role is usually designated to IT team and the system administrator has full system access, including ability to create other job roles and configure various different levels of access. For example, some user might only have access to read the data, some might have access to write it and some might have access to certain future. It is crucial to implement the rule of “least privilege” this will ensure everyone will only get access to the features and data they need. Therefore fool proof user identification and authentication mechanisms should also be implemented.

Data Encryption at Both Storage and Transmission
Businesses often doesn’t realize the importance of encryption. Encryption at both storage (at rest) and transmission (while transferred) is extremely important. It can greatly improve the security of the solution as well as it can also prevent people with malicious intent to access or intercept your data. The encryption technologies has become very advanced, now a days if you apply encryption properly, it is nearly impossible to decrypt them without proper access and decryption protocols. Encrypting any data would take very less computer resources, in fact almost none. But when you try to decrypt any data without decryption code and protocols you might be needing some very powerful super computers to be able to find the right pattern to decrypt it. Thus the encryption can greatly improve security.
The encryption ensures that your data will remain protected even if it is accessed by unauthorized means, or intercepted during the transmission. In case if someone even gets access or intercept your encrypted data, they would never be able to decrypt it. This will prevent any unauthorized access to your sensitive data. All important data types should be encrypted, especially the personal information and financial must need strong encryption. You can utilize Advanced Encryption Standards or AES which is international standard for encryption. For data transmission it is absolutely essential to transmit data through a secure connection by utilizing the SSL/TLS (Secure Sockets Layer/Transport Layer Security). This will ensure your data will remain secure and protected.

Implement Secure Software Development Life Cycle (SDLC)
The secure software development lifecycle or SDLC is not just a technique but a complete strategy. It states that the security should be implemented and prioritized at each and every stage of the software development lifecycle. Starting from planning to designing and then deployment and even for maintenance, incorporating checks and balances at every stage should remain the top priority of the software development team. Here are some best practices to incorporate security at each and every stage of the software development process:
- Planning: During the software planning process, two important things need to be prioritized. First the security requirements and compliances should be accounted at very early stage. Then the risk assessment and threat modeling should be conducted to identify potential threats, vulnerabilities and risks to ensure all these threats and vulnerabilities will be neutralized effectively.
- Designing: The design considerations and security architecture should be embedded at the core of the application. Best practices like, secure coding, encryption and system access should be incorporated in the design of the software. A thorough threat modeling should be conducted for different design choices to ensure maximum security and protection.
- Development: It is extremely crucial to ensure that your custom software development team should be well-versed with the best security practices and secure development techniques. The secure coding practices can eliminate the chances of some of the most common attacks such as SQL injection, buffer overflow, and cross-site scripting, etc. Furthermore the advanced code analysis tools both static and dynamic should be used to find any potential vulnerability in code.
- Testing: Businesses should ensure the project managers and relevant personals keep testing the application throughout the development phase. Furthermore a full-on security testing round should be conducted after development completion and before going live. Automated tools should be used to simulate attacks, and other testing methods such as penetration testing, security audits, and vulnerability testing should be conducted before going live.
- Maintenance: Once your customized software is developed, tested and deployed, then you will be needing maintenance which is a continuous process. Usually software applications require periodic maintenance, however, ongoing monitoring and patching is crucial for security. Businesses should have incident response policy and protocols in place. Furthermore any updates, customization and integration would also require in-depth security testing.
Businesses should strictly incorporate security in their software development lifecycle. This will not only make their application more resilience towards threats and vulnerability but it will also ensure the protection and safety of the data of your customers and employees. A secure development lifecycle also encourage cross-functional collaboration between the security and development team which also help improving the security and resilience of your customized software applications.
