DMARC: Determine if an Email is Really a Fraudulent Email:
The customer has recently approached DMARC Analyzer for effective phishing attacks and spoofing activities on their domains. The customer required to use only one application to counter many attacks launched from various sources. He was not able to identify the exact source of the attacks, but he suspects it may be via the servers of major credit card processors like MasterCard, Visa, or Discovery. This is the same method used by hackers to gain access to personal data stored by a person through his credit card. The customer has limited knowledge of server security but wants to adopt a comprehensive protective measure to prevent possible security breaches.
DMARC alerts are received by the provider at regular intervals. By configuring DMARC Analyzer Policy you can determine which email addresses belong to a known sender. The alerts will contain a subject line containing the IP address, port number and domain name of the sender. All the received emails will contain the message that there has been a DMARC alert received. The user will have to either reply to the message or take down the message.

There are certain measures a business can take to reduce the number of attacks on its servers. It can avoid unsecured websites and change the IP of the ones that are being used. It should also configure the firewall for the websites. However, all these measures will help reduce the number of attacks on the server but it will not stop the source of the attacks. Therefore, the company has to carry on its efforts to implement reliable anti-spam programs and have more personnel and resources to combat the rising number of phishing attempts.
There are certain steps the management takes to verify the legitimacy of an email address. First, if the email address sent by the user contains the @ character, it is most probably a fake email. The next step is to check whether the IP address belongs to a server that is active and is used regularly by the ISP. The IP address that does not point to an active server is considered most legitimate.

The security vendors and the IT personnel should also be informed about the DMAIC and take necessary actions. Currently, there is no standard definition of the DMAIC but it is used in almost all the enterprise level networks to determine the validity of an email. This is because there are many attacks happening on the network and it is very important to analyze each part of the system to identify the source of the attacks.
Another possible way to prevent the attacks from escalating is to check the validity of the email address. A good way is to check the domain name before sending the email. The IP address and the domain name must be compared before the user accepts the email. The email must not contain any dollar signs before the address and must contain only alphabets and numbers. The email must also be sent from a valid email address. It will cost some money to hire a DMAIC consultant to verify the validity of an email address but this is something that you should do for your business.
