CISA tells govt agencies to patch critical exploited flaws in 3 days

By prioritizing security updates, the directive aims to bolster defenses against cyberattacks in the public sector. It applies specifically to federal civilian agencies and impacts the overall cybersecurity landscape by setting a new standard for vulnerability management.
