Vulnerability scanning gone badPosted: May 17, 2019
Security teams often have good intentions when they want to improve the security posture of a company by introducing new tools.
In one organisation, for example, they might want to mitigate the risk of exploiting application vulnerabilities and decide to deploy a code-scanning tool. This would make sure that applications are tested for exploits before they are released. Great idea but the uptake on the use of this tool was surprisingly low and created a lot of friction.
After closer examination, it turns out that this was primarily due to challenges with communication with the development teams that would need to use the tool. The impacted teams weren’t sufficiently trained on the use of it and there wasn’t enough support from the management to adopt it.
Development teams have tight timelines and budgets to work to in order to meet the business objectives. Anything that could disrupt these aspects is viewed with caution.
As a result, applications that should have had their code scanned either hadn’t, or had to be scanned at a much later stage of the development cycle. It was not incorporated in the DevOps pipeline– the scans were run as part of a manual check before release in production. Not only the risk of having applications with flaws in them remain largely unchanged, the whole process of delivering working software was prolonged.
These new applications were being delivered to facilitate revenue growth or streamline exiting processes to reduce cost and complexity. The impact on the business was that the new functionality they were expecting took longer to materialise, resulting in users’ frustration.
What can you do to prevent such situations from happening? Here are a few recommendations:
- Communicate frequently and at the right level. Communication must start at the top of an organisation and work its way down, so that priorities and expectations can be aligned. A person may need to hear the same message multiple times before they take action.
- Articulate the benefits. Security and risk teams need to ensure they position any new processes or tools in a way that highlights the benefits to each stakeholder group.
- Provide clear steps. In order to ensure the change is successful, security professionals should clearly outline the steps for how to start realising these benefits.
Communicating and providing support on new security policies, tools and practices to impacted teams is absolutely critical. This is especially important in large organisations with many stakeholder groups spread across multiple geographies. Always keep the people in mind when introducing a change, even if it’s the one for the better.
