The VND uses many of the anti-counterfeiting features such as: traditional shadow image, optical thread, security thread, fluorescing ink, engraving. I would say that in addition, the single more effective security feature of the Dong is the material that it is made out of, polymer which is essentially a plasitic. The polymer also allows for a window-styled security thread. Remeber it's plastic so you can look right through the banknote and when you hold it up to the light you can see the number of the denomination in the window. He is an entire article you can review on the security features of the Vietnamese Dong. I've included a couple relevant qoutes from the article below.

"In the period 1997-1998, the State Bank of Vietnam organized overseas study tours on polymer technology. In countries where polymer technology is applied, polymer has high anti-counterfeit quality, besides traditional security features similar to cotton currencies (shadow image, see-through registration device, engraving), polymer bank notes have special security features with higher anti-counterfeit quality but recognizable by eyes, such as intaglio and embossing in windows. Statistics also come to the same conclusion, counterfeited polymer bank notes are fewer than counterfeited cotton bank notes (number of counterfeited bank notes/million bank notes in circulation)."
"Researches, experience and testing on the new technology have brought us to a conclusion that: If Vietnam had used new design with more security features on cotton substrate (the price could have doubled old cotton bank notes, even the quality and costs would be the same as payment notes), this would not have stopped and prevented money counterfeiting. Only polymer substrate allows anti-counterfeiting quality and reduces costs of issuance."
