Anti Spam & Phishing Protection

What is SIEM software? How it works and how to choose the right tool

Evolving beyond its log-management roots, today's security information and event management (SIEM) software vendors are introducing machine learning, advanced statistical analysis and other analytic methods to their products.


The term ‘Anti-spam’ came into being for the first time in the mid-1990s. At that time, two software engineers were working on making a list of IP addresses delivering unsolicited and unwanted emails to the recipients. After that, they distributed the list as a Border Gateway Protocol. The subscribers who were the victims of the email threats got the protocol in naming the “Mail Abuse Prevention System” (MAPS). It becomes “SPAM” when spelled backward. Later on, it was developed as the Domain Name Server Blackhole List. Still, this useful list, also known as Real-time Blackhole List or “RBL” is a primary tool in anti-spam software. Recipient verification protocol, sender policy framework, content analysis tool are some other important elements in the anti-spam software.

Case study

There are several instances of spreading spams in the servers of many companies. The Real-time Blackhole Lists do not work properly to capture spam emails from all sources. Spammers are smarter than the precaution system against them and they make sophisticated spams. In most of the cases, the unsolicited and unwanted emails remain undetected as they come from unknown or “not-yet-known” sources. There are more than 98.6 million botnets in the IP addresses. They sent spam emails from those IP addresses with good IP reputations. After gaining access to the device and internet connection, the spammer sends spam emails. They use a “zombie” device that is capable of sending malware. This is command and control malware.

Problem statement

The companies overlook outbound scanning most of the time. The reputation score of any IP address depends on their histories. If spam emails or emails containing malware are sent from a company’s server, it definitely affects their IP reputation. Whether an email is spammy or not can be detected by using a content analysis tool. It is not the botnets that necessarily hamper the network by sending spams all the time. Sometimes the employees can do this knowingly or unknowingly. Business’s IP reputation is also at stake when there are enough recipient mail filters rating the email as spam.
