With vulnerabilities on the rise since 2017, staying oblivious to cybersecurity is no longer an option. A strong Vulnerability Management strategy has to be proactive, and in order to help you with that, we've created this list of known exploited vulnerabilities in 2023.
The Cybersecurity and Infrastructure Security Agency (CISA) is at the forefront of safeguarding critical infrastructure and combating cyber threats. It has a complete catalog of Common Vulnerabilities and Exposures (CVE), where you can find a brief overview of every discovered security breach that affects a wide range of vendors.
In this article, we'll focus on known vulnerabilities identified by CISA thus far in 2023, focusing on major operating systems and software providers. Specifically, we will delve into vulnerabilities affecting Google, Microsoft, Apple, and Linux, shedding light on their potential risks and emphasizing the significance of Patch Management strategies.
