Our recent webinar about App Sec strategies was led by our special guest, Bruno Limoni, a Cybersecurity Manager who has over 15 years of expertise in cybersecurity, leading Red Teaming, AppSec, and Advanced Tooling teams at Kavak and Mercado Libre.

During the session, Bruno shared valuable tips for implementing a robust Application Security (AppSec) program.

Here are their key insights:

1. Think like developers

To implement a successful application security program, it's essential to understand and adopt the mindset and tools used by developers in their daily work. This means integrating security into processes and tools that are already familiar to them, such as project management systems like Jira, development platforms, and version control. By using tools that developers already know and use, adoption and collaboration are facilitated, ensuring that security is effectively integrated into the application development lifecycle.

2. Vulnerability management

Having an automated Vulnerability Management process is crucial. If we don't record a vulnerability, if we don't track it, and if we don't fix it, then all the work we've done becomes pointless. This ensures a rapid and efficient response to security threats, minimizing the risk of exploitation and damage.

3. Implementation of Threat Model actions

Threat models often identify potential vulnerabilities and risks in an application. It's important to follow the recommendations and actions derived from these models to mitigate risks and strengthen application security. Without proper implementation of these actions, threat models would not be effective.

4. Fix vulnerabilities

Timely fixing of vulnerabilities is essential to maintaining application security. Prioritizing and addressing critical vulnerabilities first, and then tracking fixes to ensure they are properly implemented, is crucial to protecting the application against potential attacks and security breaches.

5. Automate or die

Automating security processes allows for efficient and scalable management of security risks and challenges. As organizations grow and evolve, automation helps optimize existing resources and free up time for other important tasks, rather than relying solely on expanding the security team.

6. Metrics and visibility

Providing clear metrics and visibility on the state of application security is essential for communicating the importance of security to stakeholders, such as CEOs and decision-makers. Using understandable language and focusing on business risks helps ensure that security is a priority throughout the organization.

7. Seek allies

Collaborating closely with the development team and seeking allies within the organization can significantly improve the effectiveness of an application security program. Usually, there's always a dev who's curious and ends up being your go-to person for the AppSec team. We can implement Security Champions programs, for example, and rely on this person to always ask about how a certain vulnerability is progressing, for instance. It doesn't have to be a leader in the field; it could be someone who just joined the team or a SemiSenior. They don't need to be a decision-maker but rather someone who gradually pushes for things to get fixed. This helps us a lot.

This helps foster a culture of security and leverage the knowledge and commitment of developers to improve the overall security posture of the organization.

8. Gamification

Gamification can be an effective strategy for encouraging participation and engagement with security within the organization. Organizing events and activities involving developers, such as vulnerability fixing competitions, can motivate and incentivize safe practices and promote a positive security culture.

9. Awareness

Continuous awareness of security is key to maintaining a strong security culture within the organization. Providing educational resources and keeping developers informed about the latest threats and best security practices helps ensure that everyone in the organization is committed to the security of applications and data.

In summary, implementing an effective AppSec program involves thinking like developers, automating processes, collaborating closely with the development team, and fostering a strong security culture within the organization. With these tips, companies can strengthen their security posture and protect their applications more effectively.
