Trend Vision One™ - File Security is a scanner app for files and cloud storage. This scanner can detect all types of malicious software (malware) including trojans, ransomware, spyware, and more. Based on fragments of previously seen malware, File Security detects obfuscated or polymorphic variants of malware. File Security can assess any file type or size for malware and display real-time results. With the latest file reputation and variant protection technologies backed by leading threat research, File Security automates malware scanning. File Security can also scan objects across your environment in any application, whether on-premises or in the cloud.
The Java software development kit (SDK) for Trend Vision One™ File Security empowers you to craft applications which seamlessly integrate with File Security. With this SDK you can perform a thorough scan of data and artifacts within your applications to identify potential malicious elements. Follow the steps below to set up your development environment and configure your project, laying the foundation to effectively use File Security.
- Have Java 8 and above installed in your dev/build environment.
- Trend Vision One account with a chosen region - for more information, see the Trend Vision One document.
- A Trend Vision One API key with proper role - for more information, see the Trend Vision One API key documentation.
Download the jar from Maven Central Repository. Or for Maven, add this dependency to your pom.xml:
<dependency>
<groupId>com.trend</groupId>
<artifactId>file-security-java-sdk</artifactId>
<version>[1.1,)</version>
</dependency>The File Security SDK requires a valid API Key provided as parameter to the SDK client object. It can accept Trend Vision One API keys.
When obtaining the API Key, ensure that the API Key is associated with the region that you plan to use. It is important to note that Trend Vision One API Keys are associated with different regions, please refer to the region flag below to obtain a better understanding of the valid regions associated with the respective API Key.
If you plan on using a Trend Vision One region, be sure to pass in region parameter when running custom program with File Security SDK to specify the region of that API key and to ensure you have proper authorization. The list of supported Trend Vision One regions can be found at API Reference section below.
- Login to the Trend Vision One.
- Create a new Trend Vision One API key:
- Navigate to the Trend Vision One User Roles page.
- Verify that there is a role with the "Run file scan via SDK" permissions enabled. If not, create a role by clicking on "Add Role" and "Save" once finished.
- Directly configure a new key on the Trend Vision One API Keys page, using the role which contains the "Run file scan via SDK" permission. It is advised to set an expiry time for the API key and make a record of it for future reference.
You can manage these keys from the Trend Vision One API Keys Page.
Using File Security Java SDK to scan for malware involves the following basic steps:
- Creating an AMaaS Client object by specifying preferred Vision One region where scanning should be done and a valid API key.
- Invoking file scan or buffer scan method to scan the target data.
- Parsing the JSON response returned by the scan APIs to determine whether the scanned data contains malware or not.
import com.trend.fs.AMaasClient;
public static void main(String[] args) {
try {
// 1. Create an AMaaS Client object and configure it to carry out the scans in Vision One "us-east-1" region.
AMaasClient client = new AMaasClient("us-east-1", "your-api-key");
// 2. Call ScanFile() to scan the content of a file.
String scanResult = client.scanFile("path-of-file-to-scan");
if (scanResult != null) {
// 3. Print out the JSON response from ScanFile()
System.out.println("scan result " + scanResult);
}
} catch (AMaasException err) {
info("Exception {0}", err.getMessage());
}

}When malicious content is detected in the scanned object, scanResult will show a non-zero value. Otherwise, the value will be null. Moreover, when malware is detected, foundMalwares will be non-empty containing one or more name/value pairs of fileName and malwareName. fileName will be filename of malware detected while malwareName will be the name of the virus/malware found.

- scanFile() or scanBuffer() are designed to be thread-safe. It should be able to invoke scanFile() concurrently from multiple threads without protecting scanFile() with mutex or other synchronization mechanisms.
The communication channel between the client program or SDK and the Trend Vision One™ File Security service is fortified with robust server-side TLS encryption. This ensures that all data transmitted between the client and Trend service remains thoroughly encrypted and safeguarded. The certificate employed by server-side TLS is a publicly-signed certificate from Trend Micro Inc, issued by a trusted Certificate Authority (CA), further bolstering security measures.
The File Security SDK consistently adopts TLS as the default communication channel, prioritizing security at all times. It is strongly advised not to disable TLS in a production environment while utilizing the File Security SDK, as doing so could compromise the integrity and confidentiality of transmitted data.
