Overview:

The ARF error is a common issue encountered during scanning processes. This article explains the cause of the error and provides recommendations for improving your scanning experience.

What Causes the ARF Error?

The ARF error occurs when the host times out, resulting in a lost connection during the scan. This can happen for various reasons, including network instability or resource limitations on the agent host.

Resource Requirements:

Java is utilized as part of the scanning process, and it requires at least 1024MB of available memory on the agent host to run effectively. If this memory requirement is not met, it can lead to scanning failures and the generation of the ARF error.

Improving Scanning Efficiency

Unfortunately, the timing and occurrence of the ARF error are often beyond our control. To mitigate these issues, consider using agent-based scanning. Here’s how it can enhance your scanning experience:

• Deploy Agents to All Assets: By installing the agent on each asset within the scope, you can achieve a more stable and reliable scan.
• Parallel Scanning: Agent-based scanning allows you to scan hundreds of machines simultaneously, as opposed to relying on a single agent for remote scans. This significantly reduces scan times and increases efficiency.
• Reduced Timeout Issues: Since scans are conducted locally on each machine, you are less likely to encounter timeouts or issues related to machines being turned off during the scan.

Conclusion:

Understanding the ARF error and its causes can help you take proactive measures to improve your scanning outcomes. By utilizing agent-based scanning, you can achieve more reliable and efficient results, minimizing the risk of errors and maximizing the effectiveness of your security assessments.
