Antivirus & Anti-ransomware health check and updates (NAS)

An Antivirus & Anti-ransomware health check and updates in a Network Attached Storage (NAS) system involve ensuring that the antivirus and anti-ransomware software installed on the NAS is up to date, properly configured, and functioning effectively. This health check is crucial to protect the NAS and its stored data from malware threats, viruses, and ransomware attacks.

Scheduled Scans

Ensure that regular scheduled scans are set up to perform comprehensive system scans for viruses and ransomware. These scans should be scheduled to run at times when system activity is low to avoid performance impacts.

Case Study on Antivirus & Anti-ransomware

Problem Statement

Employee at Client company receives an email that appears to be from a trusted source. The email contains a seemingly innocent attachment that promises to offer valuable insights into the latest market trends. Intrigued and pressed for time, the employee downloads the attachment and inadvertently introduces a malware-infested file into the NAS system.

Troubleshoot

  • Detection and Quarantine:

    • During a routine scan, the software detects a file with a ransomware signature. The software immediately quarantines the file to prevent it from spreading further within the NAS. Simultaneously, an alert is sent to the CNT team, notifying them of the potential threat. The quarantined file is isolated in a secure area, ensuring it cannot execute and cause harm.​
