EventSentry v5.1: Anomaly Detection / Permission Inventory / Training Courses & More!

We’re extremely excited to announce the availability of the EventSentry v5.1, which will detect threats and suspicious behavior more effectively – while also providing users with additional reports and dashboards for CMMC and TISAX compliance. The usability of EventSentry was also improved across the board, making it easier to use, manage and maintain EventSentry on a day-by-day basis.

We also released 60+ training videos to help you get started and take EventSentry to the next level. The videos will be available to everyone for free both on YouTube and in your account area.

Anomaly Detection

One of the best real-time event log monitoring engines got a lot smarter in v5.1 and can now detect unusual behavior like the following:

  • A user who never logged on to a server/workstation
  • A user connects from a remote IP from which he/she usually doesn’t normally connect from
  • A previously unknown process starts
  • A process loads a DLL it has never loaded before (requires Sysmon)

But the best part about the new Anomaly detection is that it’s customizable – so anybody can create their own anomaly rules based on their needs.

Anomaly filters utilize insertion strings of events, so they work best with well-formatted events from the security or Sysmon event logs.

EventSentry ships with a number of built-in anomaly filters, but watch the official training video to understand how anomaly filters work to create your own.

Database Maintenance & Web-Based DB Maintenance Jobs

Also new is the ability to schedule database maintenance jobs directly from the web reports – so it’s no longer necessary to create or edit (embedded) scripts, application or task schedulers just to keep your database size in check. Simply schedule a job in the web reports and review the results after the job completed. The maintenance jobs themselves have also been improved and will attempt to free up disk space after each purge cycle when using the built-in database.

We’ve also improved the database usage page, which now shows significantly more details about the database health, including trends to help identify features that are growing in size.

Dynamic Package Updates

Unlike validation scripts, which (can) automagically update in the background so you can enjoy the latest checks with the click of a button, package updates have been a bit slower and more clunky. But this is all in the past, as package updates use the same update engine like our popular validation scripts, and can now seamlessly keep select packages up to date.

As such, users with active maintenance agreements can expect a lot more package updates to be made available to help you detect and defend against emerging threats. This new functionality also allows you to apply filters rules in JSON format directly into the management console, e.g. from KB articles or blog posts.

Permission Inventory

Keeping NTFS file permissions clean and updated can be a tedious task, even when you follow best practices (e.g. create groups for each file share and assign permissions to those groups), it can be quite difficult to stay on top of all file shares and folders, especially in medium and large-sized networks.

To which files and folders does a user have access? Who has access to critical folders?

EventSentry’s new permission inventory enumerates configured folders and their permissions (on a configurable schedule – e.g. daily), and presents them in the familiar Summary/Detailed view, making it straightforward to answer exactly those questions.

Watch the official training video for more information.

Improved Features

Every database-enabled feature in EventSentry can now store data in multiple databases, something that was previously only available in select features. This will make it easier to store all collected data in an active as well as an archive database simultaneously.

ADMonitor can now send data through the collector, the only component in EventSentry that did previously not have support for the collector.

EventSentray

EventSentray now also shows the network utilization and sports a useful “Internet Test” dialog which can test various aspects of your Internet connection – something that’s especially handy for mobile endpoints (aka “laptops”). The official training video has more information on EventSentray and how to configure & deploy it.

Compliance

Compliance requirements like CMMC, PCI, HIPAA, NIST and others continue to evolve and affect more and more companies. As important as compliance frameworks are with providing structure and guidance, companies often find it difficult to apply what are often vague rules and requirements.

Our new CMMC v2 and TISAX reports/dashboards bring together many features in EventSentry and provide a real-time status and overview of your compliance status. And our new dashboards provide actionable data that can be used to increase the security of your network – not just check boxes.

Usability Improvements

While every EventSentry release tends to incorporate little tweaks and improvements, v5.1 features many usability and troubleshooting enhancements:

  • Insertion strings in filters (when available) now show the name of the string instead of just the number, making it a lot easier to create and manage complex filters.
  • The “Save Configuration” prompt in the management console would often be displayed even when no changes were made. This has been improved significantly and you should see this prompt much less often in v5.1, with more improvements planned in future versions.
  • A new “GoTo” button will jump to any item in the tree that contains the specified text.
  • Collector users can see collector health right in the management console without having to access the web reports, while the collector status page in the web reports also shows the collector latency and throughput of individual agents.

EventSentry Training

In addition to a EventSentry’s comprehensive documentation all users now have access to a 60+ free training videos – with a total runtime of over 10 hours – organized into playlists. All videos are accessible on our YouTube channel in the Playlists section, with a training section on eventsentry.com coming soon as well. We highly encourage you to browse the new training videos – they are useful for new users and experienced users of EventSentry alike. Please upvote videos you enjoyed, we’re also happy for any feedback!

Additional Notes on EventSentry Update v3.2.1.30

Our latest patch for EventSentry v3.2 (v3.2.1.30) requires some additional information in addition to the release notes.

Heartbeat Monitoring (Agent Status)
By default, the EventSentry Heartbeat Monitor ensures that all remote agents are running by querying the status of the remote “EventSentry” service. While is an accurate way to ensure the remote agent is running, the Microsoft RPC mechanism isn’t very efficient when connecting to remote hosts across a slow (WAN) link, and concurrently checking the service status of 100+ hosts at the same time can on occasion also cause issues. In these situations, the heartbeat agent may not be able to monitor all hosts in the configured monitoring interval. Furthermore, querying the remote status of a service requires that the EventSentry Heartbeat Agent run under a domain account, otherwise the dreaded “Access Denied” error appears on the heartbeat status page in the web reports.

To address these issues for larger EventSentry deployments (500+ hosts) and deployments where the remote agents are connected through a slower WAN link, we have added the ability to query the remote agent status through the EventSentry database where the remote agents periodically check in. This check is enabled by default for new installations, but existing installations will need to make a database permission change in order to give the heartbeat agent permission to query the agent status. More information can be found here.

In the next release of EventSentry (v3.3), this functionality will be configurable, and the heartbeat agent will also be able to determine the current agent status by communicating directly with the collector service (when enabled) for even better accuracy. The Heartbeat Monitor will always attempt to revert back to the legacy method of checking the service status directly if it cannot obtain the status through other means.

Service Monitoring: Configuration Changes
EventSentry distinguishes between three types of service changes: Status changes (e.g. Running to Stopped), service configuration changes (e.g. changes to the startup type) and services being added or removed. Up until release 3.2.1.22, all status changes and service configuration changes were logged with the same event severity, which we didn’t think was very fitting since the status change of a service is very different to a change of the service itself. As such, starting with 3.2.1.30, only service status changes will be logged under the severity configured under “Monitor Service Status Changes” category. All other service changes will be logged under the severity configured under “Monitor Service Addition / Removal” category.

Management Console: Quicktools
The EventSentry QuickTools allow you to run an application/script against a server or workstation in your EventSentry configuration. EventSentry includes a few default QuickTools entries, such as “Reboot”, “Remote Desktop” and others. Starting with the latest release we added a new “Hide” option, which will not show the executed application on the desktop. This will be useful for integrating our upcoming VNC wrapper scripts (Blog article coming soon), which will allow you to install & launch a (Tiger)VNC client directly from the EventSentry management console.

EventSentry Light 3.2
Starting with this release, EventSentry Light v3.2 will also be available. We have good news for all EventSentry Light users: We have increased the number of full hosts you can remotely manage to 5, and also increased the number of network devices you can monitor to 5. As such you can now monitor up to 10 hosts with EventSentry Light completely for free.

3-2-1-Go! EventSentry 3.2.1 is out!

I am e-x-c-i-t-e-d to announce the availability of EventSentry v3.2 and tell you more about the new features and improvements. So, if you’re looking for a little bit more than the release notes then read on!

Collector
The biggest new feature in 3.2 is the collector, a new central component which enables a 3-tier architecture in EventSentry. Traditionally, the EventSentry agents have been communicating directly with email servers, databases and other services. While this usually worked well – and is still desirable in many setups – it does impose a limitation in some scenarios:

  • The SMTP server cannot be configured to allow relaying and/or accepting SMTP connections from remote clients
  • The central database cannot be configured to allow connections from remote clients
  • Agents need to communicate over an insecure medium like the Internet
  • Installing ODBC drivers is not an option
  • Remote agents communicate over unreliable network connections (e.g. satellite, laptops, …)

The collector addresses the above limitations by acting similar to a proxy between the remote agents and the service (e.g. database). In a nutshell, it provides the following benefits:

  • Agents only communicate with the collector over a single port
  • All traffic can be encrypted and compressed
  • Database connection details do not need to be stored on the agents anymore
  • All collected data is cached on the agents if and while the collector is unreachable

Whether you will need the collector or not will largely depend on your network setup. If all of your hosts are in the same data center and/or the same LAN, the collector may provide little benefit. If you are a MSP and monitoring remote sites and laptops however, then the collector is probably what you have been waiting for!

When upgrading (or installing from scratch), the post-installer configuration assistant will ask you whether you are interested in enabling the collector.

Collector Status
Collector Status in maintenance menu

If you are installing from scratch, then enabling the collector during the installation is all you need to do. When upgrading, an additional step is required – an action needs to be configured to use the collector. While the collector service is installed & started during the upgrade when selected, it will not enable any of the existing actions to use the collector. As such, if you want to route data for a specific action through the collector, that needs to be configured. Simply edit the action and click the “Use Collector” check box on the bottom left and push the configuration.

In version 3.2.1, the following actions can be routed through the collector:

  • Database
  • Email (SMTP)
  • Syslog
  • Text File

Since the collector, when enabled, is a critical component, we recommend monitoring the collector stats either through the collector status page (Maintenance -> Collector Status) or by adding the collector status tile to one of your dashboards.

There is one other advantage the collector can bring when routing emails through it:

  • Emails from multiple hosts can be grouped together (if the action polling interval is sufficiently high)
  • Action thresholds can now be applied centrally

Both features can help reduce the number of emails you receive from EventSentry, usually a popular thing to do!

Compliance Modules
EventSentry has always included the compliance tracking components which monitor and interpret Windows security events. Compliance tracking provides process, console, account management and other tracking reports. While popular and extremely useful, the compliance reports themselves don’t tell the user which particular compliance requirement they address.

Say Hello to the new compliance modules, which provide detailed, out-of-the-box reports for:

  • PCI-DSS
  • FISMA
  • HIPAA
  • GLBA
  • Sarbanes Oxley

Once a compliance module is enabled, it will install a number of reports that pertain to the specific compliance requirement that was enabled. Every report will be associated with a specific control (e.g. PCI 10.2.2) and allow you to setup a required review, job and more.

(Network) Switch Mapping
Finding the port on a switch to which a server, workstation or network device is connected is often a time-consuming and annoying process for most SysAdmins. Starting with version 3.2, EventSentry tries to ease that pain by showing exactly to which switch – and port – a host is connected to. All you need to do is add the switch to the EventSentry configuration, make sure that it can be monitored via SNMP and that it provides the MAC to port mappings via SNMP (OID 1.3.6.1.2.1.17.4.3.1.2 – iso.identified-organization.dod.internet.mgmt.mib-2.bridge.dot1dTp.dot1dTpFdbTable.dot1dTpFdbEntry.dot1dTpFdbPort). This feature should work well with all mainstream managed switched, and we haven’t run into a switch yet where this feature wasn’t provided or did not work.

Once EventSentry pulls the MAC to Port mappings, you will be able to retrieve the collected information in two ways:

  • Through the Inventory – Switch page, which will show all monitored switches and connected devices
  • Through the Inventory – Host page. If the switch port can be detected, it will be displayed next to the IP address of the network card

Since switches only provide MAC addresses, EventSentry attempts to map MAC addresses to host names and IP addresses by analyzing the hardware inventory details as well as the ARP status table when available. As such, it is recommended to enable the ARP component of the network services if the results on your switch inventory page are incomplete.

Web Reports Improvements
Starting with a visual overhaul of the interface, the web reports also received an internal overhaul to improve overall performance, especially when using multiple profiles. The performance trends page can now display multiple charts on a single page, and the host inventory page now shows the highest supported USB version on that host.

Managing multiple reports is easier now through the ability to bulk-edit reporting settings. Reports can now also be saved to a folder instead of being emailed.

Finally, the web reports are now also officially available in 6 additional languages: French, Spanish, Polish, Portuguese, Dutch and Italian. This brings the total number of supported languages in the web reports to 9!

Management Console Improvements
Improvements in the management console pertain mostly to remote update and computer management. Hosts can now be imported from a network scan, which is particularly useful when managing network devices which often don’t show up in Active Directory. The network scan is multi-threaded and can scan a class C subnet in a few seconds and even supports checking TCP ports for hosts which have ICMP disabled.

Remote update can now store the result of every activity in CSV file(s), and output from remote update can be toggled with the context menu to apply remote update actions to a sub-set of hosts easily.

Also new is the ability to export all event log filters to a CSV file allowing you to analyze the results in your favorite spreadsheet application to identify issues, duplicates etc.

That’s all folks. Time to get cracking on 3.3!

An alternative to email alerts. Part 2: Integrating EventSentry with Slack

Slack is a flexible, web-based messaging app for teams which supports multiple (mobile) platforms with the goal of streamlining communication and collaboration. In some ways, Slack feels like a combination of Hipchat, IRC and Dropbox (you can also send alerts to Hipchat from EventSentry).

Event submitted to slack by EventSentry

By creating channels (e.g. chat rooms) and also allowing for direct 1:1 communication, interacting with your team is straightforward and easy. What’s more, you can send 3rd party feeds such as Twitter notifications directly into a channel, giving you the ability to see data from multiple sources in one central location.

Slack naturally lends itself to receiving EventSentry notifications with its web-based API. And, since you can create multiple channels, it’s easy to divert EventSentry alerts into different channels, e.g. #alerts-windows and #alerts-development.

Since Slack offers native clients (e.g. Windows, MacOSX) in addition to their web-based site, you can choose to opt in to receive a visual notification every time an alert is received by Slack.

If you’re not already using Slack, then you can sign up for free at http://slack.com and see for yourself whether this is a communication platform you will want to use. If you already use Slack, then you will just need to make sure that the “slackbot remote integration” is setup. You can find information on how to enable this integration here: https://api.slack.com/slackbot.

Enabling slackbot

Once the Slackbot Remote Control integration is configured in Slack, follow these steps within the EventSentry Management Console using the slackbot URL provided by Slack to set up an HTTP action. The HTTP action will be triggered by one or more filters in an event log package to submit events/alerts to Slack.

1. Add a new action
In the left pane right click “Actions” and select “Add Action”

Adding an EventSentry action

2. Selecting the correct action type
On the “Action Selection” screen type your name for the new action (Ex: Slack), select “HTTP” and then press OK

EventSentry Action Dialog

3. Configuring the HTTP action
In the right pane you should now see the settings for your new Slack action, update the URL field with the slackbot URL provided by Slack. If you did not specify a channel in your url after the token add “&channel=%23” followed by the name of your channel.

Example: https://team.slack.com/services/hooks/slackbot?token=zk2jR22I34AK24IpEd7tdyroGt&channel=%23es-alerts

Configuring the HTTP action for Slack

4. Configuring the data to submit

In the right pane configure the Data you’d like slackbot to post to the channel, the following is suggested for basic information:

$EVENTCOMPUTER: $EVENTID:$EVENTSOURCE:$EVENTCATEGORY by $PACKAGE - $FILTER
 $EVENTMESSAGE

Configuring data to submit

Additional variables can be found in our documentation.

Once the action is configured click “Test” and you should see the test message in Slack.

5. Finishing up

You can now apply the action to any existing or new packages and filters. To learn more about filters review the documentation or walk through this tutorial.

Save the EventSentry configuration and push the configuration to the remote hosts.

Done!
