Avoiding Phishing Scams with three simple Tips.

Phishing Scams

Phishing is a common and effective tactic used by attackers to gain unauthorized access to a company’s network. It involves online messages designed to look like they’re from a trusted source. We may open what we thought was a safe email, attachment, or image only to find ourselves exposed to malware or a scammer looking for personal data.

The good news is we can take precautions to protect our important data by learning to recognize the signs, and reporting phishing attempts to your IT department to protect devices and data.

Recognize the common signs

  • Urgent or emotionally appealing language
  • Untrusted shortened URLs
  • Poor writing/ misspellings
  • Requests for personal or financial information
  • Unexpected attachments

What to do if you Suspect Phishing?

Resist opening the message. Don’t reply or click on any attachment or link, including the “unsubscribe” link. Delete and report to your IT department. If you are unsure if it is legitimate, go to the company’s website and call the person directly.

If you delete an email that turns out to be legitimate, the person can always send it to you again. That is a much better scenario than having your organization’s computer system exposed to malware. It’s crucial to be vigilant and know how to identify and report phishing attempts to protect your network.

CDX Log in Transition to Login.gov .

Log in

On August 16th, 2024, CDX transitioned to using Login.gov for all user verification, including the NetDMR and NeT reporting tools.

While the transition went smoothly for most CDX/ NetDMR users in Maine, there have been sporadic issues for some users during the past couple months.

This article will address some of the issues that have been encountered and provide updated tips for navigating the transition for users that might still be having problems.

Example of issues with transition:

  • Verification method doesn’t match: This has happened to users that have multiple Login.gov accounts. Once a CDX account is linked to a Login.gov account it cannot be linked to another Login.gov account. You can double check which account is linked by logging in at gov and clicking “Your connected accounts” on the left side toolbar. You can also modify your authentication methods and update phone numbers from the account page.
  • Email address already in-use: If you’re trying to use an email address that was already associated with a CDX account you will have to contact CDX help desk to have them deactivate the existing CDX account before you can proceed with setting up a new account. The CDX help desk is available 8:00 am-6:00 pm at 888-890-1995.

Detailed instructions, trainings and FAQs are available here: CDX Login Transition Step by Step Guide. You can also contact the NetDMR coordinator at Brett.A.Goodrich@maine.gov.

Answers

  1. b.
  2. d.
  3. c.
  4. c.
  5. c.
  6. a.

Find the volume of the tank using the formula Volume = 0.785 X D2 X Height

0.785 X 10 ft X 10 ft X 20 = 1570 cubic feet (cf)

Multiply by 7.48 to convert cf to gallons

1570 cf X 7.48 gal/cf = 11,743 gal.

  1. d.
  2. a.
  3. b.
  4. c.
  5. d.
  6. b.

288,000 gal/24 hours = 12,000 gal/hour.

Convert to gpm: 12,000 gal/hr ÷ 60 min/hr = 200 gpm.

13.b.

Use the formula for the volume of a circular tank; in this case instead of height use the length. Don’t forget to change inches to feet (6 inches = 0.5 ft).

0.785 X D2 X Length X 7.48 gal/cf

0.785 X 0.5 X 0.5 X 600 ft X 7.48 = 880.77 gal

14.b.

15.b.

The theoretical maximum height a pump can lift water using suction is 33.9 feet at sea level (14.7 psi X 2.31 ft head/psi = 33.9 ft). Since no pump can produce a perfect vacuum, in practice the maximum suction lift is lower.
