BE AWARE

The Cybersecurity Threat Landscape is fast-moving; with this in mind, we ask that you remain vigilant and alert while using devices, data, applications, and networks.

Depending on the type of breach or attack, do the following:

Threat Scenario: 

  1. Disconnect your computer from the network – via network cable or power down the computer.
  2. Inform your direct manager immediately
  3. Have as much information as possible to provide to the IT Helpdesk such as your computer name, serial number, time of the event, what is the potential cause of the event, or how did it start
  4. If an Application/Cloud Portal, i.e. Office 365, is compromised, have your Credentials to hand
  5. If credentials such as a username or password are compromised. Think about whether those credentials are used elsewhere and change those passwords
  6. If your email is compromised, do not send emails – contact the IT Service Desk via phone at 021 2429417
  7. If you do receive weird, suspicious emails and want them checked out, attach them to a new email and send them to support@deitg.com

CYBER RISK = BUSINESS RISK

How the company handles Risk is essential. However, we may not see all Risk Scenarios, so we need help and direction from our users. As mentioned, the Cyber Threat landscape moves fast; if you see potential Risk, threats, gaps in security or possible scenarios that would result in loss of data, business downtime or Risk to employee privacy, please email support@deitg.com. This Risk will be added to the Risk Register and reviewed quarterly and when threat levels are high.
