Every living creature on this planet has protection and prevents itself from any external disturbances, but now this suits the software also. Similarly, application security in eminent as the world we live in today is heavily dependent on software. Every year, more and more software applications are emerging, and the Internet of Things continues to grow.
However, with technological advancements come more cyber threats, attacks and vulnerabilities. Hackers and malicious websites pose a serious risk to the security of software codes and programs. According to the Code Security Report 2023 survey, there are over 100 cybersecurity and application development professionals. Therefore, securing code is of utmost importance for programmers and developers. This article will discuss the best practices for programmers in securing code.
What is code security?
It is the process of creating a source code to protect the other software codes and their application from any attacks from network and cyber. It identifies and addresses the vulnerabilities in source code along with the design and architecture of the software application. Many business companies store their information confidentially in software, hence securing code is practised by every programmer.
Importance of application security.
It plays several significant roles in securing code. Some are,
- Protecting sensitive data
- Preventing unauthorised access
- Mitigating security vulnerabilities
- Defending against cyber attacks
- Ensuring compliance with regulations and standards.

Benefits of securing code
Securing code is essential for reducing cyber threats, protecting valuable assets, maintaining trust, and ensuring the long-term success of software applications. Let’s briefly look into their benefits here
Customer satisfaction
Securing code improves customer satisfaction by safeguarding sensitive data and ensuring a positive user experience. This customer satisfaction will in turn increase business goals and strategies.
Cost saving
By identifying and addressing security issues in the early stage of developing a software program, developers can avoid the costs associated with fixing security flaws in the later stage or after the product’s release. It can reduce the overall cost of maintenance.
Trust and credibility
A strong security track record can significantly boost a company’s reputation since customers and partners will trust an organisation that takes security seriously. By protecting their code, companies can ensure that they meet industry and regulatory requirements, which in turn can help maintain their reputation and credibility.
Customer trust
Secure code reassures customers that their data and transactions are protected, enhancing customer trust and satisfaction and building a good relationship between the customer and the company.
Secure code management
Secure code management is the practice of securing code, managing and controlling the source code to protect it from unauthorised access. It includes implementing security best practices to protect the code from threats, such as unauthorised access and malicious attacks. Secure code management is essential for protecting sensitive property, ensuring the confidentiality of the source code, and reducing the risk of unauthorised modifications that could lead to security vulnerabilities in software applications. Here are some key aspects of secure code management,
Encryption
Encryption is a process for securing code and sensitive information, such as passwords, keys, and configuration files. It is the process of cryptographic techniques to secure and protect sensitive information in the program.
Secure development lifecycle
Integrating secure development practices, security testing, and vulnerability scanning throughout the software development lifecycle to catch and address security issues early in the process.
Version control
Version control is an essential aspect of secure code management. By implementing version control systems to track changes to the code, allowing for the management of different code versions, and enabling easy comparisons of changes. Version control systems, such as Git, have features for secure code management, such as access control, authentication, and encryption to protect the codebase from unauthorised access.

Application security best practices
Application security encompasses the measures and practices used to protect software applications from various security threats and vulnerabilities. It includes securing code and protecting an application’s data from unauthorised access, misuse, modification, or destruction. By implementing application security best practices, organisations can reduce the risk of data leaks, and unauthorised access to their applications, thereby safeguarding sensitive information. Here, we will discuss some five best practices of application security,
Authentication and authorisation
Authentication and authorisation are vital components of application security best practices. Authentication includes verifying the identity of users or systems attempting to gain access to an application or network. Authorisation involves determining what actions or resources a particular authenticated user or system can access within the application. Implementing these measures is crucial for ensuring that only particular users can access the application helping to prevent unauthorised access.
Logging and monitoring
Logging and monitoring are essential components of application security best practices. They provide visibility into the behaviour and activities within an application, helping to detect and respond to security incidents and potential threats. Logging provides a record of events and activities, while monitoring involves actively analysing this data for security issues in real time.
Secure configuration
Secure configuration refers to the process of configuring and managing an application’s settings to reduce the risk of security vulnerabilities. Organizations must establish and enforce this application security best practice to mitigate the risk of security threats and protect sensitive information.
Input validation
Input validation is a critical component of application security, involving the process of checking and validating user input to ensure that it meets the expected format, type, and range. This is done to prevent malicious data from being processed, thereby reducing the risk of various security vulnerabilities.
Vulnerability management
Vulnerability management is a methodical process used to identify, evaluate, mitigate, and track security vulnerabilities within an organization’s IT infrastructure. It includes networks, applications, and systems. The primary objective of vulnerability management is to proactively identify and address weaknesses in an organization’s security posture. This helps to minimize the possibility of exploitation by malicious attackers.
Secure code best practices
Secure code best practices are essential for developing applications with a strong defence against potential vulnerabilities and attacks. Some essential best practices include
Avoid hardcoding sensitive information
It’s not a good practice to include sensitive information like passwords, API keys or other confidential data directly in the source code of an application. Instead, it can be stored securely outside of the codebase. It can be done by using secure storage mechanisms such as environment variables, configuration files, key management systems or other similar options. It helps to avoid any security breaches that may occur if the sensitive information is directly embedded into the source code.
Least privilege principle
Access control is a principle that suggests that users and processes should only be given the minimum level of access or permissions that are needed to perform their specific tasks. The main goal of this principle is to limit access rights to the lowest level required for users, accounts, and processes to carry out their functions.
Patch management
It is the process of identifying, acquiring, testing, and installing patches and updates for software applications and operating systems. The primary goal of patch management is to eliminate security vulnerabilities and address software issues by keeping systems up-to-date with the latest patches and updates by the software vendors.
Error handling
Implement proper error handling to avoid leaking sensitive information and to prevent attackers from exploiting potential vulnerabilities. On the whole, securing code practices is essential for mitigating security risks and vulnerabilities in software development. By implementing principles such as input validation, proper authentication and authorisation, error handling, encryption, and least privilege, developers can help protect sensitive data and prevent unauthorised access to their applications.
Ultimately, integrating secure code and application security best practices throughout the software development lifecycle is crucial for building trust with users, safeguarding against cyber threats, and ensuring the integrity and reliability of software applications.
