Track projects using both Dynamic and Static projects for full flexibility.
Description. Adding additional consoles enabled horizontal scaling of the reporting, user interface, and integration resources. See Tuned PostgreSQL settings for more information on how to tune the database.
James Cairns IT Security Lead at Bow Valley College. For authenticated scanning with 100 threads we change the average asset scan time to 7.4 minutes: = (1.2 x 7.4 min x 10,000)/(.85 x 100 x 240) = ~4 engines required.
Build reports to communicate with multiple audiences from IT and compliance to the C-suite. = (K x NumberOfAssets x NumberOfScans). For example, if 10,000 assets need to be scanned in 4 hours then the following will calculate the number of engines needed: For unauthenticated scanning with 100 threads with average asset scan time of 3.5 minutes: = (1.2 x 3.5 min x 10,000)/(.85 x 100 x 240) = ~2 engines required. Accomplish More with InsightVM . As you prepare your deployment plan, think about how your network and security needs could change over time. These variables, in addition to scan configuration and network conditions, affect the scan duration and disk usage needs. For example, if assets are spread across 4 VLANS without connectivity between them, one scan engine will be required per VLAN to be able to scan assets in that VLAN. Use InsightVM to: InsightVM translates security speak into the language of IT, hand delivering intuitive context about what needs to be fixed, when, and why.
Here is the formula to calculate the total disk usage based on number of scans, number of reports, and the number of assets scanned and reported: Total Disk SpaceRequired Automatically assess for change in your network, at the moment it happens. Since the console is responsible for generating reports, integrating scan results, and serving up content for end users, it is highly recommended to delegate scanning to remote engines when scanning more than a few hundred assets. There is some additional overhead to adding engines due to the remote communication required to retrieve the result; however, adding scan engines is the best way to horizontally scale up the scanning ability to larger numbers of assets in shorter periods of time. Increasing the minimum can greatly improve discovery performance and comes at the cost of additional bandwidth usage so be aware of the demands on the network when increasing this value.
Explains primary components and provides guidelines on choosing the right host for initial deployments. Scan duration will vary based on operating system installed, responsiveness of the asset, open ports, applications installed, services running, and patch levels. Vulnerability management has stayed pretty much the same for a decade; you identify your devices, launch a monthly scan, and go fix the results. As the first vulnerability management provider that is also a CVE numbering authority, Rapid7 understands your changing network like never before, and with InsightVM helps you better defend against changing adversaries attacker knowledge gathered from the source. Here is an example of using 100 threads to scan 10,000 assets with an average asset scan duration of 3.5 minutes: = (1.2 x 3.5 min x 10,000)/100 = 420 minutes = 7 hours. Integrate seamlessly with remediation workflow and prioritize what gets fixed and when. Therefore, to determine disk usage by reporting, a CSV export of all fields across the ~1,000 assets tested was created in order to calculate the disk usage per asset that was consumed for authenticated and unauthenticated scans. How many assets can a Scan Engine handle? We will use the following values for “Average Asset Disk Usage” that we collected earlier. Scan duration depends on number of assets to be scanned, the average asset scan duration, the number of Scan Engines being used, and the number of scan threads used on the scan template. Read our Cloud Security Overview to learn more about our approach and the conrrols surrounding the Insight platform, and visit our Trust page.
How can I tune the application for maximum scanning throughout? The specifications provided are based on Rapid7’s pre-built hardware appliances, which can also serve as recommendations when not using the pre-built appliances from Rapid7: Multiple Enterprise or Enterprise Plus consoles. Peak Network Bandwidth (Mbps) = 0.4_x No.OfAssetsScanned Simultaneously_ The same formula can be used to calculate number of Scan Engines needed as well. How much disk space will I need on my console? As you can see, increasing thread count per engine is more effective than adding engines. Advanced vulnerability management analytics and reporting. Basic deployment plan. Security Console overview . The biggest storage impact on your host machine will come from scans, reports, and database backups. The test results indicate that authenticated scanning can take about twice as long as unauthenticated scanning due to the increase in the amount of local software that is assessed when having access to the asset. Note that the network configuration is also an important factor in number of scan engines needed. Please email info@rapid7.com. Scan duration may vary based on network latency. Tests were completed with a wide variety of individual assets in order to accurately capture the impact that different types of assets have on scan time, network utilization, and disk usage. Consider this example deployment situation: Scanning 1000 assets on a monthly basis with authentication, generating a single report, and storing the data for one year will take 76GB of storage. where K = disk usage of one scan of one asset, L = disk usage of for reporting on an asset, and M = the base install of the application. Rapid7 will help size and architect your deployment based on your scanning needs.
How does network latency affect scan duration? Scan data alone can have varying levels of storage impact depending on your configuration, including scan frequency and whether or not you are authenticating to the target assets. See Scan templates for information on how to tune templates for maximum performance. The Rapid7 Insight cloud, launched in 2015, brings together Rapid7’s library of vulnerability research knowledge from Nexpose, exploit knowledge from Metasploit, global attacker behavior, internet-wide scanning data, exposure analytics, and real-time reporting we call Liveboards. Now that you have your deployment plan, let’s briefly go over what the Security Console can do for you. Total disk space required for unauthenticated scanning of 10,000 assets weekly for one year and generating two reports, CSV Export of all fields and a Top Remediations with Details report, every week: = (0.037 x 10,000 x 52) + (0.052 x 10,000 x 2 x 52) + 2,500 MB. The following table provides general guidelines on how many assets a given scan engine can scan in a day based on general guidelines. | Authenticated | 307 | 7.4 minutes (range 12 s – 38 min) | 422 KB |.
