AlienVault Unified Security Management (USM) Anywhere is a cloud-based security information and event management solution that provides effective and affordable threat detection, incident response, and compliance management capabilities. USM Anywhere is well suited to mid-size enterprise environments operating in the cloud. USM Anywhere is also well suited to enterprises whose operations teams require easy deployment and management. Last, USM Anywhere is considered a highly affordable option compared to competitors. USM Anywhere lags competitors in several areas, such as application monitoring, database monitoring, and integrations with third-party solutions such as cloud access security brokers (CASB), DAM, DAP, and DLP.
Logstash is a must in an ELK stack, which I am sure is going to be the #1 case. At any point when you have several sources, Logstash can be the common point to aggregate, and categorize those data. Then send this new data to its destination. Very handy. It is free and open source. It may not be appropriate to analyze data-sets dependent on each other but from a different data source. Reason being Logstash works on data at hand, and not wait for other data to arrive. It would be unwise for Logstashh to handle complicated, long-running transformations because this is injected and ejected. The faster you do it, the safer.
The USM platform provides the essential security capabilities that work together for a fast and cost-effective way for organizations to have complete visibility into the security of their environment.
With the information gathered during asset discovery, USM will correlated that information with known vulnerabilities for continuous vulnerability awareness. In addition, USM contains an active scanner capable of scanning for over 30,000 known vulnerabilities.
To give better visibility into your network, and possibly detect intrusions that don’t follow behavioral patterns, we offer Netflow information, bandwidth monitoring, and traffic capture, all part of our behavioral monitoring capabilities built into USM.
USM Anywhere doesn't allow you to multi-home sensors. So if you have non-routable networks, you'll need to investigate the on-premise solution too.
You have to be on top of tuning else a constant stream of alerts will cause your SOC staff to begin ignoring alarms.
You have to be on top of tuning else you'll eat your allotment of storage for that month. It is really easy to exceed your storage quota if you don't proactively monitor log sources. USM could do a better job letting you know if a log source is too chatty.
Memory: Logstash is a HOG, if you are deploying it on commodity (i.e. cheap and old) hardware: You will need at least 2GB, just for Logstash. So don't expect to run your entire ELK stack on one AMD Athlon machine.
Overlap: Logstash fills in an area of the ELK stack that makes the most sense: as a log file transformer / shipper. However, if you start breaking that stack, with the addition of other components- you start seeing where features of Logstash may be implemented or solved in the additional components much easier (or better, or to a higher degree of resolution)
More Overlap: Since my team employs Syslog-ng extensively- Logstash can sometimes get in the way (and this may be a problem for DevOps stacks overall): You can configure Syslog to record certain information from a source, filter that data, and even export that data in a particular format. Logstash will pick that data up, and then parse it. However, if you don't keep your Syslog-ng configuration files, and your Logstash configuration files in sync, your results will not be what you expected, and this will translate into (sometimes) hours/days of work, hunting down a line item in a configuration file.
The centralized logging and retention for PCI compliance was our main driver, and it is meeting that need. Otherwise there has been enough frustration with the lack of documentation and the need to customize through the CLI that I would be open to alternatives.
Once you are able to navigate the different panels, finding what you need is quite easily. Before getting used it it can be a bit of challenge . Each panel is quite well laid out and the filtering search capabilities are quite strong.
As I said earlier, for a production-grade OpenStack Telco cloud, Logstash brings high value in flexibility, compliance, and troubleshooting efficiency. However, this brings a higher infra & ops cost on resources, but that is not a problem in big datacenters because there is no resource crunch in terms of servers or CPU/RAM
We do have issues with maintenance on the AlienVault USM as the disk fills up from time to time with other data sources. Sources for scanning logs and net flow data isn't calculated in regular disk maintenance and can easily fill up our disk if we do not keep an eye on it with some custom Nagios plugins. The system does properly trim logging data from logging sources properly.
With the latest release of AlienVault USM overall performance has not been an issue. We have noticed single source events per second does not scale well with the overall system. 2,000eps on a vmware system with a single source produces delays of up to an hour for us. Pages, reporting and even raw log searches are rather quick though.
Support is friendly but response time has been spotty. Also initially when we signed up there was a lot of pointing us at the documentation, which has been spotty and ad-hoc for what is supposed to be a commercial product. Overall the feel of AlienVault and the support has been of a very new and startup company that is trying to grow up out of it's open source roots, and I'm not sure if they've totally been able to make the transition to being able to meet the expectations of the enterprise customers.
I did not have any experience with "in person" training directly. The free online classes offered for a half a day are based on the actual training offered. These little teasers are very good and well worth your time to learn a few quick and dirty ways of getting more information from your SIEM
The instructor gave detailed overview and went through the labs before allowing us to attempt using them. I enjoyed the balance of time and level of instruction received. The content went deeper that usual and the lab environment was easy to use and all results were consistent. I came away from the course knowing more than i did if I had just read the course notes.
AlienVault USM was a very simple to implement and get up and running. We started with a trial version and had that up and going within an hour of receiving email instructions from the sales engineer. We never had to contact support to get the system up and going. It was extremely easy to convert over to a full license once we started with a paid version.
The cost of AlienVault is what sold us on AlienVault. However, considering the amount of time and effort that has gone into getting it set up and realizing that views and reports cannot be shared across groups makes it not worth the savings.
MongoDB and Azure SQL Database are just that: Databases, and they allow you to pipe data into a database, which means that alot of the log filtering becomes a simple exercise of querying information from a DBMS. However, LogStash was chosen for it's ease of integration into our choice of using ELK Elasticsearch is an obvious inclusion: Using Logstash with it's native DevOps stack its really rational
The AlienVault USM is not very scalable. Some scalability can be achieved by installing additional sensors, but this only offers 500eps per sensor and is still overall limited by the installation type of VM or physical. We have also noticed the EPS (events per second) is rated overall and not towards a single source. A single source on a very healthy VMware partition tops out at 2,000eps for us, no matter how we configure it. Maybe this is a problem of the 5.2 release?
Once you hit the 150 asset mark, you have to jump to their unlimited license. There is no middle ground. We were only 10 or so assets above the 150 so we had to chose to either not monitor those assets or pay the price of the upgrade.
AlienVault brings all the information to one place which makes it much quicker to track down problems.
It is very difficult to give any figures on ROI, as it depends on many factors, and in a Telcocloud environment, it is much complex to find out; however, I would give some points below on ROI
ROI based on flexibility is very high, as it reduces the time to find RCA
ROI based on integration is very high because it supports multi-vendor environments, avoiding vendor lock-in & works across multi-cloud setups
ROI on resource consumption is less because Logstash in 2-3 times more resource-intensive as compared to its lightweight alternatives resulting in latency
