A hot backup, also known as an online backup or dynamic backup, is the process of backing up data while the system continues to be in operation. This means that there is no need for system downtime or interruption in services while the backup is taking place. It is mostly used in systems where operations are critical and cannot afford any downtime, such as databases and servers that must be available 24/7. The hot backup method allows for data to be backed up at regular intervals with minimal impact on the system’s performance, ensuring that the organization can maintain continuous service levels.

References: The concept of hot backup is aligned with the ECCouncil’s Network Defender (CND) objectives and is supported by industry best practices as detailed in sources like MiniTool1 and NinjaOne2, which discuss the advantages of hot backups in maintaining uninterrupted service and business continuity.

 Network Interface Cards (NICs) operate at the Physical layer of the OSI model. This layer is responsible for the actual physical connection between devices. It transmits individual bits from one node to the next and is involved in the electrical, mechanical, procedural, and functional aspects of activating, maintaining, and deactivating physical connections. It’s also where hardware like cables, switches, and NICs come into play.

In the context of risk assessment, an incident that has a very high probability of occurring and the potential to impact almost 80% of a business is considered an extreme risk. This categorization is based on the severity of the impact and the likelihood of the event. The risk matrix, a tool used in risk assessment, helps in the classification of risks by considering both the impact and the probability of potential incidents. An event that affects such a significant portion of the business would typically necessitate immediate attention and the implementation of mitigation strategies to prevent substantial loss or damage.

References: The Certified Network Defender (CND) curriculum includes principles of risk assessment and the use of risk matrices to categorize and prioritize risks. It outlines that risks with high impact and high probability should be classified as extreme, requiring urgent action12.
