Advanced Threat Protection

Advanced Threat Protection (ATP) offers protection against advanced malware, zero-day exploits, and targeted attacks not detected by the intrusion prevention system by scanning downloaded files. The user receives the downloaded file immediately after the hash DB lookup, which compares a hash of the file with the Barracuda database to see if it is a malicious file. Simultaneously, the file is uploaded to the Barracuda ATP cloud, but only if the file is 10 megabytes or less. Archives are unpacked and the files they contain are sent to the ATP cloud with the same restriction that only unpacked files 10 megabytes or less are sent to the ATP cloud for inspection. In the ATP cloud, those files are emulated in a virtual sandbox and their behaviour is analyzed. Depending on the behaviour of the file, it is assigned a threat level that is transmitted to the appliance. If the threat level exceeds the ATP threat level threshold, the file is blocked; otherwise, it is delivered.

Advanced Threat Protection can be used for HTTP, HTTPS, FTP, and FTPS traffic. For HTTPS and FTPS, SSL Inspection must be activated.

The following file types are scanned by the Barracuda ATP cloud: 

• Microsoft Office files – doc, docx, ppt, pps, pptx, ppsx, xls, xlsx
• OpenOffice – rtf, open office document extensions
• Microsoft executables – exe, msi, class, wsf
• macOS executables 
  
• PDF documents – pdf
• Android APK files – apk
  
• ZIP Archives – 7z, lzh, bz, bz2, chm, cab, zip
• RAR Archives – rar4 and rar5
• TAR Archives – tar
• GZ Content – Content compressed with gzip

Risk Scores

The ATP service classifies all files in one of four categories:

• High – Files classified as high risk exhibit behavior normally only found in malware.
• Medium – Files classified as medium risk pose a potential risk.
• Low – Files classified as low risk are considered to be harmless. Some residual risk remains.
• None – No suspicious activity was detected.
  

Reporting

You can create reports and notifications using Azure Log Analytics Workspace. Your SecureEdge service must be connected to Azure Log Analytics Workspace. For more information, see How to Configure Log Streaming to Microsoft Azure Log Analytics Workspace.
