MYDLP Antispam Filter Solution: Block Malicious Email Traffic

Over the past 10 years or so, the problem with irresistible spam, countless unwanted and unrequested emails has declined for the most part. Before anti-spam software became commonplace, users are bombarded by a constant onslaught of spam and its a productivity killer. But that's not the worst of it. Not only does the massive volume of spam chew up email bandwidth without adding any value whatsoever, but there are also a lot of malicious threats hiding in much of the spam traffic trying to get in.

Now, the wave of spam has slowed down, and thanks to anti-spam software.

Anti-spam refers to solutions that focus on blocking and alleviating the effects of unwanted emails (spam) to email users. To achieve this objective, different types of anti-spam solutions have been integrated with many email and Internet service providers (ISP).

Here's a look at how a coordinated anti-spam effort works.

Modern-day anti-spam comes with an array of capabilities designed to prevent unwanted email from entering your network. It covers a broad spectrum of filters, scanners and other types of applications. Some anti-spam services work from a statistical method, while others use heuristics or predictive algorithms. To sort email in sophisticated ways, anti-spam service providers may monitor email signatures, IP addresses or other data, which reduces spam.

The emergence of anti-spam software adds to the ongoing conflict between email recipients and unsolicited email senders. ISPs and email providers are working to block certain types of email marketing. However, senders may find ways to disguise the message's origins, or imitate another sender's signature or other email features. Likewise, senders may find ways to deceit anti-spam tool algorithms and break through filters to reach the user's inbox.

It starts with your Internet Service Provider because that is where it all. To catch spam as it comes in, they use a sophisticated software on their email servers and this way they prevent it from reaching you.

Most ISPs that offer email accounts also give anti-spam software for their users. But since spam solution is not their primary business, so one cannot be sure how good they are when it comes to catching spam. That's why it becomes critical to take matters into your own hands to protect your system.

Well, no DNS filtering solution will block all the malicious websites, because, in order to do so, we have to make sure a webpage is malicious. If a cybercriminal puts up a brand-new phishing webpage, it will take some time for the DNS to check and verify and before they add it to the blocklist. Nevertheless, a DNS web filter will block 95 percent of the malicious websites.
