- Database System VulnerabilitiesThe weaknesses in a database system that can be exploited by malicious actors to gain unauthorized access, disrupt operations, or manipulate data. Such vulnerabilities could stem from a variety of factors, including but not limited to software bugs, improper configurations, weak security controls, or lack of timely updates and patches. Identifying and mitigating these vulnerabilities is crucial in protecting the data held within the database system.
- Data Breaches Incidents where information security is compromised, leading to the unauthorized access, disclosure, alteration, destruction, or loss of protected, sensitive, or confidential data. Breaches can affect personal data, intellectual property, and trade secrets and can result from cyberattacks like hacking, malware, and phishing due to negligence or insider threats. They often lead to significant financial, reputational, and legal consequences.
- Data Bus A communication system within a computer or device consisting of various wires or traces on a circuit board, which transmits data between components. It allows the transfer of data and instructions from one part of the computer to another, and its width (in bits) determines how much information can be transmitted at once.
- Data Center Power Redundancy The implementation of backup power sources and systems within a data center to ensure its continuous operation, even during power failures or disruptions. Power redundancy can include multiple power feeds, uninterruptible power supply (UPS) systems, and backup generators.
- Data Circuit Terminating Equipment (DCE) Devices that act as an interface between data terminal equipment (DTE) and a data transmission circuit. These devices could include modems, switches, and routers. DCE devices provide a point of connection for networking and facilitate the communication process. Securing these devices is crucial as they can be potential points of exploitation by threat actors.
- Data Classification The process of organizing data into categories for its most effective and efficient use. Classification helps manage risk by applying appropriate controls based on the sensitivity and value of the data. It typically involves categorizing data as public, internal, confidential, or secret to guide users on how to handle and secure it. Proper classification is crucial for compliance, data security, and minimizing the risk of data breaches.
- Data Classification Scheme A structured framework used to categorize data based on its level of sensitivity, importance, and legal obligations. Such schemes allow organizations to effectively manage and protect their data by setting rules for access, storage, and transfer and ensuring that adequate protective measures are applied consistently throughout the organization's data ecosystem.
- Data Communications The process of transmitting and receiving digital or analog data between two or more points. The data can be transferred through various mediums like wire, optical fiber, or airwaves and can be anything from simple text files to complex multimedia presentations. Secure data communications are pivotal for maintaining the integrity and confidentiality of transmitted data.
- Data Contamination The process by which data becomes corrupt or tainted due to the introduction of erroneous, misleading, or irrelevant information. This can happen through human error, data integration issues, or malicious activity, such as a cyber-attack. Contaminated data can lead to inaccurate analyses, misguided business decisions, or compromised machine learning models. In cybersecurity, it is essential to maintain the integrity of data by implementing controls that prevent contamination, such as input validation, data sanitation processes, and activity monitoring, to detect and mitigate any contamination incidents quickly.
- Data Control Language (DCL) A type of syntax used in SQL databases that manages permissions on different database objects. DCL commands such as GRANT and REVOKE allow specific roles or users to access or restrict certain actions on the database, ensuring that only authorized individuals have the right level of access to perform their duties.
