Regression testing is typically done with software that automates validation processes to efficiency test changes within in an network’s software infrastructure. Software properly developed, deployed, and tested should continue to perform when the following are applied:
- Software patching
- Software enhancements
- Configuration changes
Before an administrator begins regression testing, future applied changes need to be ranked based on severity. While there are systems like the Common Vulnerability Scoring System (CVSS) used to calculate vulnerability severity ratings, some vendors — like Microsoft — provide the service when rating vulnerabilities for their proprietary software and appliances.
Though vendors and systems like an CVSS can help, an administrator must still carefully review changes due to their own network infrastructure complexities. When applying software patches things such as likelihood of exploitation, number of assets affected, and the level of sensitive information residing on the hosts should be taken into consideration.
After changes to an infrastructure, regression testing is a way to verify that the quality of the new code complies with the old to ensure the organization’s systems will not be negatively impacted. It is a best practice to perform regression testing after any change, especially with many organizations scheduling daily, weekly, and monthly changes.
Threatcare, the leader in Proactive Data Security, offers the Threatcare Suite. The Suite is an Enterprise SaaS that acts as a virtual purple team. The Threatcare Suite can execute BAS (Breach and Attack Simulations) as well as a wide variety of other simulations to test your defense in depth.
Administrators looking to validate changes in a timely manner will get what the most of out of an automated regression testing tool.
When there are continuous software releases on an organization’s infrastructure, regression testing can become a hassle. Administrators who manually try to find time and resources for the job often have a hard time. Due to this fact, automated regression testing software is popular by quickly helping to validate bug fixes while ensuring newly added features won’t create problems existing software suites.
