Which Check Point software blade prevents malicious files from entering a network using virus signatures and anomaly-based protections from ThreatCloud?

The appropriate software blade that prevents malicious files from entering a network is the Antivirus blade. This software blade employs both virus signatures and anomaly-based protections to detect and block malware. It leverages ThreatCloud, which is Check Point's cloud-based threat intelligence service that provides real-time information about various threats, including malicious files and known signatures.

The Antivirus blade continuously scans files entering the network and uses signature-based detection to identify known malware. Additionally, it employs anomaly-based detection techniques, which look for behaviors that deviate from established norms to catch new or unknown threats that signature-based detection might miss. This dual approach allows for a robust defense against a wide range of malware.

In contrast, the Firewall primarily focuses on controlling traffic and enforcing security policies but does not specifically handle file-level malicious content. Application Control is designed to manage and restrict the use of applications rather than scanning files for malware. Anti-spam and Email Security are aimed at identifying and filtering out unwanted or malicious emails but do not generally deal directly with file scanning for viruses.
