Step 0: Assessing the need for application security

The internet is full of security risks. Hackers are getting smarter, using more complex methods to break into systems. They target everything from websites to mobile apps to look for any weak spot. With businesses relying more on software, the chance of being hit by a cyber attack is high. Here's how to conduct an application security assessment:

Start by identifying all your applications.

The foundation of a solid Application Security Program is knowing what needs protection. Make a list of every application your organization uses or develops, including external-facing web applications, internal management systems, and mobile apps. An inventory helps in understanding the breadth of potential exposure and prioritizing security efforts.

Get to know the threats you're up against

Understanding the threat landscape is crucial in keeping up with the latest security vulnerabilities, potential attack vectors, and how these threats could specifically impact your applications. Tools and resources that provide up-to-date threat intelligence can be invaluable here.

Check your compliance with security standards

Depending on the nature of your applications and the data they handle, there might be specific security standards and regulations you need to adhere to, such as GDPR for applications processing personal data from the EU, or HIPAA for healthcare-related applications in the U.S. Making sure compliance is a key part of assessing your application security needs.

Look for vulnerabilities through assessments and testing

To understand where your applications might be vulnerable, conduct regular vulnerability assessments and penetration tests. Vulnerability assessments can be automated to some extent and will scan for known vulnerabilities, while penetration testing involves simulating cyber attacks to find weaknesses.

Decide what to fix first based on risk

After identifying vulnerabilities, it's important to prioritize them based on their severity and the potential impact on your organization. This helps in efficiently allocating resources to fix the most critical issues first.

Keep an eye on your applications continuously

Application security is an ongoing process. Continuously monitoring your applications for new vulnerabilities and adapting your security measures to the evolving threat landscape is crucial for maintaining a robust defense.

‍

Step 1: Establishing the foundation

Establishing the foundation of an Application Security Program involves a clear-eyed assessment of where you currently stand in terms of security and a thorough understanding of what you need to protect. Here’s how it works:

Evaluate your current security status

Start by taking stock of your existing security measures. Look at the security protocols you have in place, the tools you're using, and how your team responds to security incidents. It's like doing a health check-up for your application security - you need to know your strengths and where you're vulnerable. This evaluation can involve reviewing past security incidents to assess the effectiveness of current security controls and determining the security knowledge and awareness within your team.

Identify your key assets

This could be customer data, intellectual property, or the infrastructure your applications run on. Think about what would hurt your business the most if it were compromised or lost. Identifying these assets helps you understand where to focus your security efforts. It's not just about protecting everything equally; it's about knowing what matters most and securing it accordingly.

Understand potential risks

With your key assets in mind, the next step is to identify the risks to those assets. This involves understanding the different ways your applications could be attacked or compromised. Are there specific vulnerabilities in your technology stack? Could social engineering be a threat to your team? What about risks from third-party services or libraries you use? Understanding these risks is crucial for planning how to mitigate them.

‍

Step 2: Strategic planning and goal setting

When building an Application Security Program from scratch, strategic planning and goal setting are crucial steps. This phase is about laying out a clear roadmap for what you want to achieve with your security efforts and ensuring that security becomes an integral part of your software development process.

Defining objectives for the security program

The first step in strategic planning is to define clear, actionable objectives for your security program that align with your overall business goals and address specific security needs identified in your initial assessment. For example, if your assessment revealed a high risk of data breaches, one of your objectives might be to strengthen data encryption and access controls.

‍

Objectives should be SMART: specific, measurable, achievable, relevant, and time-bound. This could include goals like reducing the number of vulnerabilities in your applications by a certain percentage within a year or achieving compliance with a specific security standard by a set deadline.

Integrating security into the software development lifecycle (SDLC)

Integrating security into the SDLC means making security a part of every phase of your software development process, from planning and design to deployment and maintenance. This is often referred to as shifting left, which means considering security early in the development process rather than as an afterthought.

‍

Here’s how you can integrate security into the SDLC:

• During the planning phase, include security requirements alongside functional requirements. This sets the expectation that security is a priority from the start.
• In the design phase, use threat modeling to identify potential security issues based on the design of your application and plan how to mitigate them.
• During development, enforce secure coding practices and incorporate tools that scan code for vulnerabilities as it's written.
• In the testing phase, conduct security testing alongside functional testing, including automated vulnerability scans and manual penetration testing.
• After deployment, continue to monitor your applications for new vulnerabilities and respond to any security incidents that occur.



Integrating security into the SDLC not only helps in catching and mitigating security issues early but also fosters a culture of security within the development team. It makes security a shared responsibility rather than the sole domain of a security team.

‍

Step 3: Selecting tools and technologies

Selecting the right tools and technologies is a critical step in building an Application Security Program. The tools you choose should not only address your specific security needs but also integrate well with your existing development processes. Here's an overview of essential security tools and some tips for choosing the right ones for your needs.

Overview of essential security tools

• Static Application Security Testing (SAST) tools analyze source code at rest to detect security vulnerabilities. They are used early in the development lifecycle, even before the code is run, which makes them a key part of the shift left approach.
• Dynamic Application Security Testing (DAST) tools test the application in its running state to simulate attacks against a live application to find vulnerabilities. They are useful for identifying issues that only appear during execution.
• Interactive Application Security Testing (IAST) combines elements of SAST and DAST by testing applications from within using agents or sensors for real-time vulnerability analysis during manual reviews, automated tests, or while the application is in use.
• Software Composition Analysis (SCA) tools analyze the open-source and third-party components of your applications for known vulnerabilities. Given the widespread use of libraries and frameworks in software development, SCA is crucial for managing third-party risk.
• While not a tool in the traditional sense, Threat Modeling is a methodology used to identify, communicate, and understand threats and mitigations within the context of protecting something of value.

Tips for choosing the right tools

• Assess your specific needs. Consider the types of applications you're developing, the technologies you use, and your most critical security concerns. The right tools for a web application might be different from those needed for a mobile app.
• Integration with your development environment. Choose tools that integrate seamlessly with your existing development and deployment pipelines. Tools that disrupt your developers' workflows are less likely to be adopted effectively.
• Consider the learning curve. Evaluate the complexity of the tools and the required expertise to use them effectively. Tools that are too complex can become counterproductive if your team doesn't have the skills to use them properly.
• Scalability. Ensure the tools can scale with your development efforts. As your application portfolio grows, your security tools should be able to keep up without becoming a bottleneck.
• Vendor support and community. Consider the level of support provided by the tool vendor and the presence of an active user community. Good support and an active community can be invaluable resources for troubleshooting and best practices.
• Cost vs. Benefit. Finally, weigh the cost of the tools against the benefits they provide. This includes not just the purchase price but also the operational costs related to training, integration, and maintenance.

‍

Step 4: Implementing best practices

A successful Application Security Program is about creating a culture of security that permeates every aspect of the development process.

‍

• Adopt secure coding practices to prevent vulnerabilities like SQL injection and XSS.
• Conduct regular developer training on the latest security threats and mitigation techniques.
• Perform code reviews to catch security issues early, using both peer review and automated tools.
• Carry out security audits with both internal teams and external experts to ensure compliance and identify weaknesses.
• Integrate security into every stage of the SDLC, from requirements gathering to deployment.
• Validate all input to ensure that only properly formatted data is processed by your applications.
• Encode output to prevent injection attacks, especially in web applications.
• Implement strong authentication and authorization mechanisms to control access to sensitive data and functionality.
• Develop a secure error handling strategy that doesn't leak information.
• Encrypt sensitive data both in transit and at rest, and manage encryption keys securely.
• Use threat modeling during the design phase to identify potential security issues.
• Include security testing as part of your regular QA processes, using dynamic analysis and penetration testing.
• Foster a culture of security within the organization that makes it a priority at all levels and encourages open communication about security issues.
• Reward and recognize secure coding practices and proactive security measures by team members.

‍

Step 5: Monitoring and continuous improvement

For an Application Security Program to be effective, it needs to include monitoring and continuous improvement. It's not just setting up systems to keep an eye on your applications but also using data to make sure your security efforts are paying off.

How to set up continuous monitoring systems

Continuous monitoring involves using tools and processes to constantly watch over your applications and the environments they run in. This can help you catch security issues before they turn into bigger problems. Here's what it involves:

‍

• Automated scanning. Use automated tools to regularly scan your applications for vulnerabilities. This should be part of your CI/CD pipeline so that you're continuously checking for issues with every update.
• Anomaly detection. Enforce systems that can detect unusual activity that might indicate a security breach, such as unexpected access patterns or spikes in data traffic.
• Log management. Collect and analyze logs from your applications and infrastructure to help you understand what's normal and spot deviations that might signal a problem.

Using metrics to track program effectiveness

To know if your Application Security Program is working, you need to measure it by setting up metrics that can give you insight into how well you're doing and where you might need to improve. Consider these metrics:

‍

• Number of vulnerabilities: Track the number and severity of vulnerabilities discovered in your applications over time. A decreasing trend is a good sign, but pay attention to any spikes that might indicate new issues.
• Time to remediate: Measure how long it takes to fix vulnerabilities once they're found. Faster is generally better, but quality matters too—you want to make sure fixes are thorough, not just quick.
• Compliance rates: If you're subject to regulatory requirements, track how well you're meeting them. This can include compliance with standards like PCI DSS, HIPAA, or GDPR.
• Incident response times: Keep an eye on how quickly you can respond to security incidents, such as the time to detect an issue, assess it, and start responding.
• User feedback: Don't overlook qualitative metrics. Feedback from your development team, security team, and even end-users can provide valuable insights into how well your security measures are working and how they're affecting user experience.

‍

Step 6: Fostering a security culture

Having a successful security culture within an organization is about more than just implementing tools and processes; it's about shaping attitudes and behaviors toward security. Here's how to encourage a culture where security is a shared responsibility and valued component of the development process:

Encouraging Collaboration Between Teams

Security shouldn't be the sole responsibility of a security team. Instead, it should be a collaborative effort that involves developers, operations, quality assurance, and even non-technical staff. Encourage collaboration by:

‍

• Cross-functional training: Organize training sessions where members from different teams can learn about the security challenges and responsibilities of other roles. This helps in building empathy and understanding across teams.
• Regular security meetings: Hold regular meetings with representatives from all teams involved in the development and deployment of applications to discuss security concerns, share insights, and coordinate security initiatives.
• Security Champions program: Establish a security champions program where interested individuals from various teams act as liaisons between their team and the security team. They can help in disseminating security best practices and gathering feedback from their teams.

Promoting Proactive Security Measures

A proactive approach to security involves anticipating and mitigating security risks before they become issues. Here's how to promote this mindset:

‍

• Reward and Recognition: Recognize and reward proactive security behaviors, such as identifying potential security issues before they are exploited or suggesting improvements to existing security processes.
• Security as a Key Performance Indicator (KPI): Incorporate security metrics into the KPIs for all relevant teams, not just the security team. This could include metrics like the number of security bugs identified and fixed, compliance with secure coding standards, or participation in security training.
• Encourage Open Reporting: Create an environment where team members feel comfortable reporting security concerns or incidents without fear of blame or retribution. An open reporting culture helps in identifying and addressing security issues early.
