Physical security measures are essential for protecting an organization's physical assets and environment from unauthorized access, theft, and damage. Locking file cabinets and installing biometric locks directly relate to controlling access to sensitive areas or information within a physical space. Biometric locks enhance security by requiring unique biological characteristics, such as fingerprints or retinas, ensuring that only authorized personnel can enter specific locations. Similarly, locking file cabinets protects sensitive documents from unauthorized individuals, safeguarding confidential data physically.

Other options, while important for overall security, focus on different aspects of information security. Encryption techniques are aimed at protecting data integrity and confidentiality in transmissions or stored data but do not pertain to physical barriers or controls. Creating strong passwords is a cybersecurity measure specifically aimed at protecting digital accounts and systems, rather than addressing the physical security of spaces. Firewalls protect networks from cyber threats but do not enforce any physical security over actual locations or equipment. This distinction clearly differentiates the correct answer and illustrates why it is the most fitting under the category of physical security measures.
