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.

Application whitelisting is a security approach that allows only pre-approved applications to execute within a system or network. This method operates on a ‘default deny’ principle, meaning if an application is not explicitly listed as approved, it will not be allowed to run. This is in contrast to application blacklisting, which operates on a ‘default allow’ principle where all applications are allowed to run unless they have been specifically identified as malicious or undesirable and added to a blacklist. Whitelisting is generally considered more secure because it prevents any unapproved applications from running, which can include new or unknown threats. However, it can be more challenging to maintain as it requires a comprehensive understanding of all the necessary applications for business operations.

References: The concept of application whitelisting and its differentiation from blacklisting is well-documented in cybersecurity literature and aligns with the guidelines provided by the EC-Council’s Certified Network Defender (CND) program. It is also supported by various cybersecurity frameworks and best practices, including those from authoritative sources such as the National Institute of Standards and Technology (NIST).

The correct order of steps to analyze the attack surface begins with identifying the indicators of exposure. This step involves recognizing the elements within the system that could potentially be exploited by threats. Following this, the attack surface is visualized to understand the scope and scale of potential attack vectors. Next, a simulation of the attack is conducted to assess the effectiveness of the current security measures and identify any vulnerabilities. Finally, the attack surface is reduced by implementing measures to mitigate the identified risks and vulnerabilities, thereby enhancing the overall security posture.
