- OECD (Organization for Economic Cooperation and Development) an international organization that works to promote economic growth and development through cooperation among its member countries. It also develops and publishes best practices and guidelines for a variety of topics, including IT security and cloud computing.
- Off-boarding The process of terminating an employee's access to company resources and systems, as well as returning company property, upon their departure from the organization. It is used to protect the company's data and assets and to ensure compliance with legal and regulatory requirements. Examples include revoking the employee's access to company systems, disabling their email account, and conducting an exit interview.
- Office for Civil Rights (OCR) A subdivision of the U.S. Department of Health & Human Services that enforces federal laws designed to ensure equal access to education and to protect privacy and the handling of sensitive information. It's particularly notable for overseeing the application of the Health Insurance Portability and Accountability Act (HIPAA), which includes regulations for the secure handling and transmission of health information, a significant concern for healthcare providers and related businesses.
- Official Information Official information refers to data or records designated as confidential, sensitive, or for limited distribution and protected according to legal or policy requirements. Access and dissemination are restricted to individuals with proper authorization to prevent unauthorized use, ensuring that such information is not compromised. Examples include personnel records, proprietary business details, and certain governmental communications.
- Offline files Data that is stored on a local device rather than on a network or cloud-based system. It is used to access and edit files without an internet connection and to improve performance and reliability. Examples include storing documents on a laptop or desktop computer or using an offline database for a mobile application.
- Offsite storage The practice of storing data or physical assets at a location that is separate from the main facility or office. It is used to protect against disasters, such as fires or floods, and to provide additional security for sensitive information. Examples include using a remote server for data backup or storing physical documents in a secure storage facility.
- Omnidirectional Antenna A wireless transmitting or receiving antenna that radiates or intercepts radio-frequency signals in all directions horizontally. These antennas are often used when broad coverage is required, such as in wireless networks where the position of the receiving device is not fixed or when a signal needs to be broadcast to multiple other points from one central location.
- On-boarding The process of introducing a new employee to the organization and its culture, policies, and systems. It is used to ensure that the employee has the knowledge and tools they need to perform their job effectively. Examples include providing orientation and training, introducing the employee to their team and colleagues, and setting up their workstations.
- One-time Cryptosystem A cryptographic system that uses a different key for each message or communication. It is used to provide high-level security for sensitive information, as the key cannot be reused or derived from previous messages. Examples include the one-time pad cipher and the Diffie-Hellman key exchange.
- One-Time Pad A symmetric-key cipher that uses a random key that is as long as the message and is used only once. It is considered the most secure encryption method, as the key cannot be derived from the ciphertext. Examples include using a one-time pad to encrypt classified documents or to secure communication between two parties.
