Secure an Application

Secure an Application

Securing an application is the process of ensuring that the application is free from vulnerabilities and risks that could compromise its functionality, integrity, availability, or confidentiality. Securing an application involves applying security principles and practices throughout the application lifecycle, from design and development to deployment and maintenance.

Securing an application can be challenging for various reasons



Modern applications are often composed of multiple components, layers, and technologies that interact with each other and with external systems and services. This creates a large and dynamic attack surface that can be exploited by attackers. Securing an application requires a comprehensive and holistic approach that covers all aspects of the application architecture and environment.



The demand for faster and more frequent delivery of applications has led to agile and DevOps methodologies that emphasize speed and efficiency over security. This can result in security being overlooked or neglected in the application development process. Securing an application requires a shift in culture and mindset that integrates security into every stage of the application lifecycle, from planning and coding to testing and deploying.



The shortage of qualified and experienced security professionals makes it difficult to find and retain talent that can secure applications effectively. Moreover, many developers lack the security knowledge and skills to write secure code or to identify and fix vulnerabilities. Securing an application requires a continuous investment in security education and training for both security and development teams.



Applications often need to comply with various regulations and standards that govern the collection, processing, storage, and transfer of personal or sensitive data. These may include GPDR, SOC 2, PCI DSS, HIPAA, NIST CSF, etc. Non-compliance can result in legal penalties, reputational damage, and loss of trust. Securing an application requires a thorough understanding of the applicable regulations and standards and their implications for the application design and operation.

Perform a threat modeling


A threat modeling is a systematic analysis of the potential threats and risks that an application may face. It helps to identify the assets, boundaries, entry points, data flows, and attack vectors of the application. It also helps to prioritize the most critical and likely threats and to define countermeasures and mitigation strategies. Some of the tools that can help with threat modeling are Microsoft Threat Modeling Tool, OWASP Threat Dragon, and IriusRisk.

Implement secure coding practices


Secure coding practices are guidelines and standards that help developers write code that is free from vulnerabilities and follows security principles. Some of the secure coding practices are input validation, output encoding, error handling, encryption, authentication, authorization, logging, etc. Some of the tools that can help with secure coding are Snyk Code, SonarQube, and Veracode.

Conduct security testing


Security testing is the process of verifying that the application meets the security requirements and does not have any vulnerabilities that could be exploited by attackers. Security testing can be done at different stages of the application lifecycle, such as static analysis, dynamic analysis, penetration testing, fuzz testing, etc. Some of the tools that can help with security testing are Snyk Open Source, ZAP, Nmap, Burp Suite, and Metasploit.

Deploy security solutions


Security solutions are systems or services that provide protection for applications in production environments. They can help to prevent, detect, and respond to cyberattacks, as well as to monitor and audit the security posture of applications. Some of the security solutions are firewalls, web application firewalls (WAF), intrusion prevention systems (IPS), antivirus software, encryption software, etc. Some of the tools that can help with security solutions are Snyk Container, Imperva WAF, Cloudflare WAF, Bitdefender Antivirus, and VeraCrypt.

Maintain security awareness and updates


Security awareness and updates are essential for keeping up with the evolving threat landscape and ensuring that the application remains secure over time. Security awareness involves educating and training developers and users on the latest security trends, best practices, and threats. Security updates involve applying patches and updates to fix vulnerabilities or bugs in the application or its dependencies. Some of the tools that can help with security awareness and updates are Snyk Advisor, OWASP Top 10, NIST CSF, CVE database, and Patch Tuesday.
