Cybercrimes or cyberattacks are increasing rapidly with continually expanding IT services. These days, one of the most common attacks that a company experiences is a zero-day attack. Zero-day describes a situation in which security teams or security experts are unaware of software vulnerabilities and have “0” days to work on a security patch or upgrade to address the vulnerabilities. Suppose the software vulnerabilities are not promptly identified and resolved. In that case, they may have significant adverse effects on the business, including financial loss, data theft, the shutdown of operations, unauthorized access to the network or system, and damaged reputations.
The most prevalent systems that hackers can target with zero-day attacks are:

Operating systems
Hardware
Internet of Things (IoT) devices
Firmware
Business SaaS
Web browsers
Open-source software

This blog will provide an overview of zero-day attacks and the methods to provide protection against zero-day attacks.
