What kind of systems does the term 'environmental failures' specifically refer to?

Environmental failures specifically refer to systems related to the management of environmental conditions, which includes heating and cooling systems. These systems are crucial for maintaining optimal operating conditions for hardware and data centers. If such systems fail, it can lead to overheating, humidity issues, or even physical damage to equipment and data loss. Proper functioning of heating and cooling systems is essential for ensuring the reliability and longevity of IT infrastructure. This understanding highlights the importance of environmental controls in the context of organizational security and operational integrity.

In contrast, options related to physical security, malicious code, and data protection do not encompass the environmental aspect that heating and cooling systems address. Each of those other categories deals with different types of challenges, such as security against unauthorized access, threats from malware, or safeguarding data, which do not specifically pertain to environmental conditions.
