Malware Protection

Topics Discussed

Product Overview

The Malware Protection services provide protection against malicious software ("malware"). Armor utilizes an enterprise-class malware protection application and deploys the application agent with the Armor Agent. The malware protection agent registers with an Armor management console that receives scan results and activity logs in real-time. Armor malware protection provides an extra level of detection on your hosts to identify suspicious activity and alert you to it. In addition to eradicating malware, each exploit generates community-powered insights—the collective knowledge of these insights is applied across more than 1,200 client environments.

The malware protection agent registers with the Armor management portal (AMP) console, which receives scan results and activity logs in real-time. These logs are entered into the Spartan platform database, where SOC teams monitor alerts 24/7/365. If a critical detection occurs, the security information and event management platform (SIEM) will alert in near real-time. If new malware is discovered during our security operations and analytics, We work directly with the anti-virus (AV) vendor to have signatures created, and our teams create custom mitigation and/or detection techniques as threats emerge. This means an attack on one Armor customer provides protection for all others.

Frequently Asked Questions

How often are Malware scans performed?

Real-time scans continuously monitor for malware. Every time a file is received, opened, downloaded, copied, or modified, a real-time scan occurs. (In comparison, manual and scheduled scans only detect malware at specific times, when you run them.) If Deep Security detects no security risk, the file remains in its location and users can proceed to access the file. If Deep Security detects a security risk, it displays a notification message, showing the name of the infected file and the specific security risk.

Does Malware Protection help keep my environment compliant?

Yes. Armor's Malware Protection service addresses key change control processes required by PCI DSS, HIPAA, HITRUST, SAN CSC, NIST, and other frameworks.

To fully use this screen, you must add the following permission to your account:

• Read AVAM

• Write Trend Manual Scan

• Read Trend Manual Scan

Enable Trend Sub-Agent

As a prerequisite to installing Malware Protection, you must install the Trend sub-agent. Use the commands below to manage the Trend sub-agent.

For cloned assets with the Trend sub-agent installed, users will still need to enable the modules and run recommendation scans as needed.

You can also manage the Trend sub-agent in the Armor Toolbox.

Install Trend Sub-Agent:

Windows: C:\.armor\opt\armor.exe trend install
Linux: /opt/armor/armor trend install

Uninstall Trend Sub-Agent:

Windows: C:\.armor\opt\armor.exe trend uninstall
Linux: /opt/armor/armor trend uninstall 

Trend Sub-Agent Status:

Windows: C:\.armor\opt\armor.exe trend status
Linux: /opt/armor/armor trend status

The following Trend commands are not relevant to the Malware service.

View Service Health Data for Malware Protection

1. In the Armor Management Portal (AMP), in the left-side navigation, click Security.

2. Click Malware Protection.

3. Navigate to the Malware Protection Service table.

4. The status icons above the Malware Protection Service tableindicate the overall Malware Protection status for all of your instances. There are three status types:

   • OK (in green) indicates that your server's agent has communicated (hearbeated) with Armor.

   • Warning (in yellow) indicates that your server's agent appears to be reporting behind its expected timelines.

   • Needs Attention (in red) indicates that your server's agent has not properly communicated (heartbeated) with Armor.

The number of active scans will display in the top right corner of the table.

To learn how the overall Malware Protection status is determined, see Understand service health data for Malware Protection (below).

Understand Service Health Data for Malware Protection

In the Malware Protection screen, the Malware Protection Service table displays the various malware protection statuses of your virtual machines or instances:

• Green indicates a virtual machine in a Secured Malware Protection status.

• Yellow indicates a virtual machine in a Warning Malware Protection status.

• Red indicates a virtual machine in a Critical Malware Protection status.

The Malware Protection status can change based on the following two conditions:

• The date of your last scan (Last Scan)

• The date that Armor last received your data (Last Communication Date)

The overall status of your virtual machine is based on the individual status of your virtual machine's subcomponents (subagents), including Malware Protection.

Condition 1. Date of last scan

If the last scan for Malware Protection took place between 7 to 13 days ago, then the Malware Protection status changes from Secured to Warning.

If the last scan for Malware Protection took place 14 days ago or more, then the Malware Protection status changes from Warning to Critical.

Condition 2. Date that Armor last received your data

If Armor last received data between 24 to 48 hours ago, then the Malware Protection status changes from Secured to Warning.

If Armor last received data over 48 hours ago, then the Malware Protection status changes from Warning to Critical.

Armor labels the Malware Protection status based on the worst status of the two conditions. For example, if the date of your last scan was 9 days ago, but Armor last received your data 72 hours ago, then overall, the Malware Protection status is Critical.

View Detailed Malware Protection Data

The Malware Protection details screen displays the malware that has been detected in your virtual machine or instance. This screen only shows data for the last 90 days.

In the Malware Protection screen, you can run a manual scan for your virtual machine or instance. 

• The Scan button will display for a particular virtual machine or instance if the sub-agent has heartbeated within the last four hours, AND a scan is not already in progress for that virtual machine or instance.

• The Scan button will NOT display if an initial scan has not been performed by Trend Micro, nor if the sub-agent has not heartbeated for that particular virtual machine or instance within the last four hours.

• The Scan button will be disabled if there are five active scans running on the account.

1. In the Armor Management Portal (AMP), in the left-side navigation, click Security. 

2. Click Malware Protection.

3. Within the Malware Protection Service table, locate the desired virtual machine or instance, then click Scan.

Troubleshooting

If you do not have any malware events listed, consider that:

• Armor did not detect any malware events on this host in the last 90 days.

  • If a malware event is detected, Armor will contact you based on your notification preferences. To learn how to configure your notification preferences, see Update notification preferences.

• You do not have permissions to view malware events.

  • You must have the View AVAM permission enabled to view malware vents. Contact your account administrator to enable this permission. To learn how to update your permissions, see Roles and Permissions.
