Why is software quality important to security?

In many cases, it is defects in software that can cause vulnerabilities, including security concerns. This is why it is essential that your software is of high quality in order to avoid these issues.

In many cases, it is defects in software that can cause vulnerabilities, including security concerns. This is why it is essential that your software is of high quality in order to avoid these issues. As well as software defects, it is sometimes due to a lack of expertise from software developers – but this is not always the case. As a company, it’s normal for you to attempt to reduce your overheads. However, investing in poor-quality, outsourced software often increases costs due to issues that could have been avoided had you purchased better quality software in the first place.

Software security flaws

A software security flaw includes any defect within your software that has the potential to pose a risk to your security, and this is caused by human errors. Unfortunately, a software defect can take place throughout the life cycle of software development and can be due to a simple misinterpretation. Not all software defects pose a risk to security, some may just affect how the software actually works. However, because some do, if you increase the quality of your software, therefore reducing the number of software defects, then your security also increases.

Some security flaws can lead to vulnerabilities; for example, certain flaws can mean that a program is left vulnerable to attacks when a security boundary is crossed by the input data. With high-quality software, these security flaws wouldn’t exist, and therefore wouldn’t pose any threats.

Mitigating software flaws

There are various approaches used to limit the number of software defects, and many of these tools and processes can also be used to get rid of security flaws. However, many still manage to go unnoticed due to regular methods not anticipating the existence of attackers. Therefore, these existing methods need to be extended for this purpose. Some mitigations can be as simple as using a bounded string copy operation in replacement of an unbounded one. Others may involve filtering traffic to prevent attacks.
