Given a limited budget, the more important factor to focus on would be training. Allocating time to limit possible human error eliminates any risk of fund loss due to human error. Then, focus on acquiring the most well-rounded, layered, and multi-use software that covers the most well-known risks.

Risk Assessment

The first step would be to decide what parts of the overall system are the most important ot vulnerable. Maybe the software is out of date or is prone to a certain kind of attack. This helps ensure that money is being spent on the things of utmost importance and not on redundancies that can be later addressed. 

Allocate Budgets

Due to the reasons above, the best allocation for funds would be somewhere around 60% to 40%. 60% towards training staff on the appropriate conduct of these complex systems and 40% towards the software itself. This is why it is crucial to invest in good quality systems, as a strong, sound system will have overlap within its capabilities. While the allocation might be higher for training purposes, it is generally cheaper than buying multiple, possibly redundant software programs for the company or business. There are even resources here that make it possible to get quality frameworks and tools for low prices, so price does not directly correlate to bad quality and unreliable systems. A feedback loop can also be used as a cost-effective way to stay on top of and manage systems.

Conclusion

In conclusion, human error is one of the most common reasons for security breaches. To eliminate at least some of the risk, and keeping a limited budget in mind, allocating around 60% of funds to employee systems training is the most logical.  The remaining funds can be used for systems that can be layered and built upon as a strong foundation for the cybersecurity of the company or corporation.
