Unless you’re under a rock, you know that the WannaCry Ransomware cyberattack swept worldwide headlines last week.
Organizations scrambled to apply the latest Microsoft security patch to their computers to prevent the spread of the attack. It’s estimated that the ransomware attack hit more than 300,000 victims in 150 countries.
The purpose of this document is to walk the user through the integration for collecting Security Manager firewall change events and logs into Immediate Insight (also note: Security Manager activity, such as configuration collection via SSH, will also be collected). Now all of the log feeds that you send to Security Manager can be easily directed from Security Manager to Immediate Insight – saving you from having to setup additional or duplicate feeds.
Additional Hardware Considerations
The firewall log collection adds considerable overhead to data collection on Immediate Insight. It is recommended that you add 1GB of RAM and 500MB of storage to your existing memory and storage configuration on Immediate Insight to compensate for the additional overhead. For 2,000 EPS or higher Security Manager firewall log collection, it is recommended that you add an additional vCPU to your existing vCPU configuration on Immediate Insight.
A Note About Future Security Manager Software Updates or Upgrades
The following files on Security Manager are modified as part of this change and do not persist across upgrades of Security Manager:
Please be aware that if you update or upgrade Security Manager (i.e. from 8.6.0 to 8.6.2) you will need to re-apply the changes to those files in this document.
It is important to backup your configuration and data ahead of making changes to your system(s). If you are running your Security Manager and/or Immediate Insight systems in VMware – we recommend taking a snapshot prior to making changes. In addition:
Note: this integration requires Immediate Insight version app-2016-04-07 (or newer) – from the “2016” build, which can be obtained by typing ‘update’ from the Immediate Insight CLI. Security Manager 8.5 or newer is required.
Immediate Insight and Security Manager must be configured with correct certificates so that they can securely exchange data. Here are the required steps;
To collect logs and change events from Security Manager, you will need to install an additional component in Immediate Insight for logs and configure a Security Manager Collector in Immediate Insight for both the logs and events.
To enable the collection of firewall logs being sent to Security Manager - login to the Immediate Insight CLI.
To setup a data collector for the change events and logs you will need valid admin level credentials and connectivity to Security Manager. Login to Immediate Insight GUI, go to DataFlow -> Collectors and click the + button of the Collectors from, then select ‘Security Manager Collector’
Go to the DataFlow -> Collectors screen
Scroll down to your new Security Manager Collector, and check that the Status says ‘running’ (it can take a minute or so to initially change from ‘Connecting’ to ‘Running’) – if it does not say ‘Running’ confirm your credentials, certificates, and network connectivity before proceeding.
If Status is ‘running’ you will see Security Manager Change Events show up as indicated by the ‘Records’ counter.
Note: depending on how Security Manager Configuration Change Monitoring is setup, it may take anywhere from minutes to hours to see data, below is an example of configuring hourly change monitoring in Security Manager for a particular device managed by Security Manger (please see Security Manager documentation for full details on how to enable and configure the ‘Change Monitoring’ feature)
Go back to the Immediate Insight Search tab, then do one of the following to search for Security Manager Change event records.
Searches can also be combined with other non-Security Manager data sources allowing for context and correlation of information from across your security related ecosystem. (For further details on Searching with Immediate insight please consult the User Guide)
So you’ve purchased a new firewall. Now what?
You’ve got to decide which access is allowed, which isn’t allowed and whether or not rules are compliant with internal and regulatory standards.
Things are running along smoothly and then the dreaded “change.” A user submits a new access request and the fun begins. Is this access necessary? Safe? Compliant? And what happens when it’s time to retire unused rules?
How Effective Security Management Can Help Teams Cover the Exponentially Increasing Gap between Technology & the Resources Available to Manage It
Security teams today are under tremendous pressure due to the rising frequency and impact of breaches and a business that wants to move faster and faster. The answer to both of these challenges has always been to add more technology and staff resources.
However, each new technology added creates complexity. More rules are created and more data is generated. As networks continue to evolve, this complexity will only grow. And while staff resources may increase, they will never match the exponential growth of technology.
FireMon calls this phenomenon The Complexity Gap and has set out to help security teams close it.
Join us for this webinar with Frost & Sullivan where we’ll explore the causes of “The Gap” and how workforce multipliers such as intelligence and automation help staff manage their security more efficiently and more effectively.
Helping Enterprise Security Teams Improve Resource Efficiency & Reduce Overall Risk Exposure
Firewall technology has come a long way since its initial, most rudimentary forms. Next-Generation Firewalls (NGFW) are the latest development, and organizations are accelerating adoption to the new technology. But NGFWs aren’t a fix-all solution.
