Adding security to your SDLC? It’s critical, but easy to fall into traps that undermine your efforts. Here are 10 common pitfalls to watch out for.

–

01 – Delaying security integration

Starting security late – such as in testing – leaves software vulnerable from the start. Security should be foundational, beginning with clear requirements and planning in the design phase.

02 – Overlooking risk assessment

Skipping risk assessment is like navigating a minefield blindfolded. Regular assessments uncover vulnerabilities early, allowing you to mitigate risks before release.

03 – Weak preventative measures

Security tools and controls must be relevant and robust. Poorly chosen measures waste time and let flaws slip into production. Align security controls to real threats.

04 – Over-relying on expensive tools

No tool is a silver bullet. Investing in one–size–fits–all security solutions without understanding their capabilities often leads to inefficiencies. Select tools tailored to your tech stack and workflows.

05 – Poorly configured scanners

Security scanners can be invaluable, but misconfigurations cause false positives and frustration. Regularly review and tune configurations to get actionable insights.

06 – Neglecting security metrics

Security is an iterative process. Without measurable data, you can’t assess effectiveness or find areas for improvement. Track key metrics to refine security strategies.

07 – Failing to automate and integrate

Manual security processes won’t keep pace with modern threats. Siloed tools slow development and increase human error. Automate security testing and integrate security into CI/CD pipelines.

08 – Ignoring prioritisation and remediation

Identifying vulnerabilities isn’t enough – failure to prioritise and remediate creates backlogs and leaves critical risks unaddressed. Take a risk–based approach and focus resources where they matter most.

09 – Isolating security teams

Security isn’t just a technical discipline – it’s a collaborative one. Isolated security teams miss critical development and product context. Foster cross–functional collaboration from the start for better security outcomes.

10 – Skipping continuous improvement

A once–yearly pen test isn’t enough. Security must be an ongoing effort, with continuous monitoring, regular updates, and iterative improvements to stay ahead of threats.
