Reconciling Performance and Security in High Load Environments

Most perceive security fixes and improvements as a necessary evil, because security is much “less tangible” than primary product functionality in terms of potential revenue. On top of not bringing any “meaningful” value to the overall system, security comes at a cost of potential performance degradation, as it steals precious CPU cycles and memory from the overall resource pool.

Because of the above in a performance-driven environment product and infrastructure security are either heavily avoided altogether or forcibly imposed by security teams, excusing themselves with numerous legal and compliance requirements. The fear of potential performance penalty and the need to balance performance vs security often leads to insecure architectures and designs or unnecessary complexity.

All this usually makes the rest of the organisation dislike and distrust security in the long term. But what if we can show that security actually improves performance? This presentation explores how to drive security in a high performance environment and make it a welcome and natural part of the product lifecycle.

Designing Secure Architectures the Modern Way, Regardless of Stack

This talk aims to attack two typical conflicts any security architect is well familiar with: 1. Most of the design thinking for preventing security incidents and performance bottlenecks focuses on avoiding known risks in a known way. However, most of the time this approach leads to...

Keep Calm and Secure Your CI/CD Pipeline

Shifting left significantly reduces costs and diminishes release delays. Continuous security validation should be added at each step from development through production to help ensure the application is always secure. We can then switch the conversation with the security team from approving each...

Security Vulnerabilities Decomposition

In most companies security is driven by compliance regulations. The policies are designed to contain the CWEs each company is interested to comply with. The result of this approach is a high number of insecure applications are still produced and injection is still King. Is there another way...
