Business information leak - Network Unit

Description

Different network units are used to identify the vulnerabilities present in the organization's network.

Impact

  • Leverage breaches or security bottlenecks to cause a leakage of information.
  • Collect security event logs from the internal network.

Recommendation

  • Check the network segmentation.
  • Secure transport encryption is crucial to encrypt the transmission in this layer.

Threat

Anonymous atacker in local network.

Expected Remediation Time

⌚ 30 minutes.

Code Examples

Compliant code

Secure transport encryption is enabled

public static void CreateTestMessage(string server){
SmtpClient client = new SmtpClient(server);
client.UseDefaultCredentials = true;
client.EnableSsl = true;
client.Send(message);
}
