Spam Detection in Email Security: Core Technologies To Understand

Cyber crime is a growing industry. Now that email communications are the primary means of doing business, criminals look to the web to carry out fraud. Email security attacks in the form of spam are coming in 24/7/365 days of the year, and organizations should have constant protection from this threat in order to avoid disaster. Email spam is a leading cause of network downtime and virus infections on company networks, not to mention how these problems can lead to sensitive data leakage.

 

An advanced email security solution should be employed by firms in order to protect themselves from email spam. Learn to identify the best email security solutions by familiarizing yourself with their core technologies, which should come as standard. Today, we look at reputation analysis.

 

What is reputation analysis?

 

Reputational analysis in email security is a technology that tracks the reputation of a huge database of IP (internet protocol) addresses that your enterprise comes across. An IP address can be seen like a street address- when you live in a bad area of town, people will know because they recognize your address. The time idea applies to IP addresses. The most important part of reputation analysis technology is speed and efficiency. In order to identify spam, the email security system will have to vet the IP address first, rather than scanning the whole message. This helps to eliminate huge amounts of spam before time is spent scanning every email.

 

We have discussed reputational damage from outbound spam before, and this is one drawback of relying on reputational analysis alone. While the system may identify bad IP addresses on inbound email, it will not mark your own IP as untrustworthy. However, a comprehensive email security system will include other technologies to weed out outbound spam also.
