Application security, often abbreviated as AppSec, involves measures and countermeasures taken during an application’s lifecycle to prevent threats, vulnerabilities, and attacks. It’s a broad field encompassing the security considerations during application design, development, deployment, maintenance, and regular upgrades.
Application security is not merely a one-time event, but rather it is an ongoing process. It includes the methodologies, tools, and practices designed to protect applications from threats from unauthenticated access, data breaches, or other cyber-attack forms. It is also about managing the risk associated with an application’s usage throughout its entire lifecycle.

This is achieved by implementing security standards, protocols, and tools that identify and mitigate potential threats.
As the importance of security grows and organizations emphasize shared responsibility between development, IT, and security teams, IT service management (ITSM) professionals play a critical role in making application security an inseparable part of the IT environment. In this article, I’ll explain how application security is becoming an important part of ITSM practice, common technologies and tools, and best practices that can help you enhance security for your organization’s application portfolio.
The Importance of Application Security in ITSM
Application security is more than just an IT concern; it is a business concern. With businesses increasingly relying on applications for their day-to-day operations and customer interactions, ensuring the security and reliability of these applications has never been more critical. This is where ITSM comes into play – with its focus on delivering and managing IT services that meet business needs, ITSM is increasingly emphasizing application security.
One of the primary goals of #ITSM is to ensure that IT services are always available when needed. This is where application #security plays a pivotal role. Read about it here. Click To TweetMaintaining Service Availability
One of the primary goals of ITSM is to ensure that IT services are always available when needed. This is where application security plays a pivotal role. By identifying and mitigating potential threats, application security ensures that applications are always up and running, guaranteeing service availability.
In the absence of proper application security, applications could be vulnerable to various forms of attacks that could lead to downtime. This could have severe business implications, including financial losses and damage to brand reputation. Hence, application security is critical in maintaining service availability in ITSM.
Preserving Integrity and Confidentiality
Maintaining the integrity and confidentiality of data is another crucial aspect of ITSM. With businesses handling sensitive data, any breach could have catastrophic consequences. Application security helps safeguard the integrity and confidentiality of data by preventing unauthorized access and modifications.
Through techniques such as encryption and secure coding practices, application security ensures that data remains secure and unaltered during transmission and storage. It also provides controls to restrict access to sensitive data, thereby preventing data breaches.
Enabling Business Continuity
Business continuity is all about ensuring that critical business functions continue to operate even in the face of disruptions. In the digital age, applications are integral to most business functions, making their security paramount to business continuity.
Application security aids in business continuity by ensuring that applications are robust and resilient to attacks. By proactively identifying potential vulnerabilities and threats, application security helps in planning for contingencies, thereby minimizing the impact of disruptions on business operations.
Compliance with Regulations
In today’s regulatory environment, compliance with data protection and privacy laws is not just a legal requirement but also a business necessity. Non-compliance can lead to hefty fines and damage to a brand’s reputation.
Application security plays a crucial role in ensuring compliance with these regulations. By enforcing strict access controls, encryption standards, and data protection measures, application security helps businesses meet their regulatory obligations.
This article looks at some of the most commonly used application #security testing methods. #ITSM Click To TweetOverview of Application Security Testing Methods
Application security relies on automated tools, which can help organizations deal with the growing complexity of modern applications and the threat landscape. Here are some of the most commonly used application security testing methods.
Static Application Security Testing (SAST)
Static application security testing, often called SAST, is a “white box” testing method (it tests an application based on knowledge of its inner workings). It is performed in a non-runtime environment and analyzes the application source code for security vulnerabilities. SAST is known for its ability to find common coding errors and vulnerabilities early in the development lifecycle, making fixing any issues easier and less costly. However, it cannot identify runtime vulnerabilities or check the application’s interaction with other systems.
Dynamic Application Security Testing (DAST)
In contrast to SAST, dynamic application security testing (DAST) is a “black box” testing method (it tests an application from an outsider’s perspective). DAST involves testing the application in its running state and is used to find vulnerabilities that are typically not identifiable in the static state. The primary advantage of DAST is its ability to identify runtime errors and issues related to the application’s interaction with other systems. However, it’s important to note that DAST requires a working prototype of the application, which makes it less suitable for the early stages of development.
Interactive Application Security Testing (IAST)
Interactive application security testing (IAST) is a relatively new approach that combines elements of both SAST and DAST. IAST tools operate in the application’s runtime environment allowing them to effectively identify both static and dynamic vulnerabilities. With IAST, organizations can detect security issues in real-time during testing, making it a powerful tool in the ITSM ecosystem.
Penetration Testing
Penetration or pen testing is a method used to test a computer system, network, or application to identify vulnerabilities that attackers could exploit. In the context of ITSM, pen testing is essential as it helps identify weaknesses in an organization’s security posture. It’s important to note that while pen testing can be automated, it requires skilled testers to operate the automated tools, simulate the most relevant attacks and identify vulnerabilities.
Application Security Best Practices for ITSM
While understanding and implementing application security testing methods is crucial, adopting best practices that ensure application security is a holistic part of your organization’s ITSM ecosystem is equally important.

Security should not be an afterthought in the software development lifecycle (SDLC). Instead, it should be integrated from the very beginning. By incorporating security measures in the initial stages of SDLC, you can identify and fix vulnerabilities early, saving time and reducing costs. This practice, known as DevSecOps, promotes a “security as code” culture with ongoing, flexible collaboration between release engineers and security teams.
Regular Security Training
Regular security training is crucial to keep all team members updated on the latest threats and security practices. An effective ITSM ecosystem ensures that all staff, not just those in IT, are trained in basic security measures. This can significantly reduce the risk of successful phishing attacks and other user-targeted threats.
Incident Response Planning
Incident response planning is another essential practice in a robust ITSM ecosystem. A well-crafted incident response plan will ensure your team is ready to react promptly and efficiently to any security incidents or breaches. It will help to minimize the damage, reduce recovery time and costs, and protect your organization’s reputation.
Access Controls
Implementing strict access control measures is a simple yet effective way to enhance security posture. You should ensure that access to systems and data is granted on a need-to-know basis. Robust change management and regular access control audits can help identify and rectify any potential issues before they can be exploited.
Patching and Updating
Finally, regular patching and updating of systems is a key security practice. Outdated software can have vulnerabilities that cybercriminals can exploit to access your systems. An effective ITSM ecosystem will have a patch management process to ensure that all software and systems are always up to date.
In conclusion, ITSM is not just about managing IT services but also about managing risk, optimizing end-user experience, and aligning IT goals with the business’s goals. By understanding and implementing the application security testing methods and best practices in this article, you will be well on your way to developing an ITSM ecosystem that fully supports and contributes to application security.
