10. How do you balance security concerns with business needs and priorities?

As a security consultant, balancing security concerns with business needs and priorities is vital for the success of any project or organization. While security is of utmost importance, ignoring business needs can potentially harm a project or an organization. Here is how I manage the balance between these two:

  1. I prioritize security by performing a threat and risk assessment before recommending any solution. This assessment helps to identify potential security threats and the level of risk they pose to the organization. I then recommend a solution that addresses these identified threats.
  2. I communicate the importance of security to business stakeholders. This involves breaking down complex security jargon into terms understandable by both technical and non-technical stakeholders so they can understand the risks, benefits, and potential compliance issues that come with different options. By helping business colleagues understand the value of security, they are less likely to push against a decision that prioritizes security.
  3. I provide viable alternatives with varying levels of acceptable risk so that the decision-makers are better informed to make a decision that considers all aspects of the project, including security.

The results of balancing business needs and security is evident in my previous work. For example, while working with a financial services organization, I was tasked with implementing new security measures to protect customer data. Through the evaluation and implementation of a Secure Sockets Layer (SSL) certificate and two-factor authentication (2FA), the organization was able to protect customers’ sensitive data while still continuing to conduct business smoothly. The organization saw a 25% increase in customer trust and satisfaction in the following year after these security measures were implemented.
