Baseline Strategy

After the disk space requirements are identified, the next approach is to establish a baseline on how much disk space Tenable Security Center consumes in production. This is important for future disk requirements, backup size estimations, and other scenarios where such information is valuable. The following are the scenarios where disk space is consumed:

• Identify the type and number of scans being run on a daily, monthly, quarterly, and yearly basis.

• Reports that are being generated and kept.

• Frequency of backing up the system and storing it locally.

• Trend data (for example, trending line charts and trending area charts).

The baselining is flexible and can be done in various ways, as long as the goal, which is to know the periodic graphical storage consumption, is achieved.
