Julie Security helps a water utility protect its facility against Cyber-attacks on its Operational networks and maintain a secure operation.

Objectives

  1. Gain visibility into the network and all assets.
  2. Detect and alert on OT & IT cyber threats.
  3. Anomaly detection.
  4. Forensics investigations.
  5. Continuous monitoring.

Challenges

  1. Bots & mining malware.
  2. Compliance with regulations (AWIA).
  3. Lack of documentation and visibility of assets and networks.
  4. Inbound and outbound connections to the internet on the operational network.

Solution

  1. Configure the firewall well, because the operational network is using the internet.
  2. Network Monitor and traffic analysis with Julie Security Intrusion Detection.
  3. Remove & mitigate the malware.
  4. Update Anti-virus software.
  5. Blocking and restricting communication to the internet for devices in the operational network.
  6. Handle vulnerabilities that were reported.
  7. Avoid lateral movement of attackers to the rest of the network of hackers by segmentation of the networks.
