Fighting spam has become a time-intensive process at the network level.
FREMONT, CA: Electronic mail is one of the easiest and convenient channels where people can transfer information and share data with others. However, it is common to receive information or emails that contain malicious attachments. Some email service providers filter and mark such dubious emails with the word “spam,” indicating to the recipient that the email is either a junk or unsolicited email with malicious content sent to several recipients by the sender. Clicking on links in such email may direct the recipient to phishing websites or sites that download malware to the computer. It is not surprising that most people have encountered several spam emails in the inbox, and people’s behavior online contributes to the spam messages they receive. Here is how to fight spam from inside the network.
Implementing Spam Software Protection
Several software packages are available to fight spam, but leveraging these to battle it from inside the network can be problematic. Server-powered anti-spam software is a better option, as it can be deployed at the gateway and avoids the administration complexities connected with computer-based products. This software also has far more data at its disposal and can identify spam more effectively.
Detect and Deal With Compromised Hosts
If enterprises have detected one compromised host, there will be more other vulnerable hosts in the network. Once firms have identified the abuse, immediately contact the client to alert them and advise them to clean their machine leveraging multiple AVs and malware scrubbers. Honey Pot Systems can be installed inside, outside, or in the DMZ of a firewall design. It is essential to remember that Honey Pots should not replace the traditional security systems. They are an additional layer of security.
Fighting spam from within the network starts with educating customers. Firms can instruct them to use strong passwords and two-factor authentications. Managing a password history for every customer to maintain absolute control is essential. Lastly, limit new customers’ rights to the network and only provide them wider access as the trust increases. Restrictions can include server creation, new domain creation, bandwidth boosts, and API access.
