When it comes to zero-day vulnerabilities, the best approach is preventative action
Zero-day vulnerabilities are software security flaws with the potential to be exploited by cybercriminals – they’re unintended flaws found in programs or operating systems that, if left unaddressed, create security holes that can and almost certainly will be exploited. The problem stems from the traditional software development and QA testing processes that fail to identify bugs and flaws that manifest in live usage. Static and dynamic testing, RASP, and vulnerability assessments all look for known problems or known fallible coding techniques which makes it difficult to identify zero-day vulnerabilities (which are, by definition, unknown.) Even using blue-green or canary staging approaches, software bugs may not be seen and will propagate, meaning the code or application problems caused by these flaws are pushed live, because that code is not tested with production traffic. Since the existing testing methodologies have trouble finding these critical zero-day vulnerabilities, other approaches are being tried, including advanced log analysis and bug bounty programs.
