Advanced Spam Blocking Software

As the amount of cybercriminals continues to grow, in tandem with the increasing complexity and sophistication of cyber attacks, the necessity of installing the strongest possible cybersecurity measures has continued to be one of the most important investments that a group can make.

Everyone can remember how simple it was to spot a spam email as recently as five years – be it an email from a supposed African dignitary or some correspondence informing you that you have won a foriegin lottery that you did not enter – however nowadays that are much better disguised and may even look like they were sent to you by one of your supervising managers.

All it takes is for one slip up by a member of staff and hackers will be able to steal data, lock you out of your own network or pretend to be you in order to share malware further afield. Due to this it cannot be emphasized enough that you need to configure you security measures to address this.

The most successful cybersecurity measures included the following operational features:

• One front end spam test like Real Time Blacklists or SURBL filters – these will to block emails from known sources of spam
• A measure to tackle spam sent to non-existent email addresses.
• Greylist to tackle incoming spam email from unknown sources. This returns all incoming mail, unless specified, asking for it to be resent. Spam servers will typically not respond and these sources will be blocked going forward.
• Whitelisting allows you to mark certain sources and domains as safe and the mail coming from here will be allowed to land in inboxes without being quarantined. This means you can avoid the igmanony of losing a business critical email.
• Outbound email scanning will stop your servers from becoming blacklisted. Every outgoing email will be reviewed to search for URLs that link to malware-hosting websites or contain zip files created to install tracking software to websites. This is to address any attempt to take over the email account of any members of your staff.

Installing a solution that will include all of these features will see you spam detection rates jump to just below 100%. Free solutions may boast detection rates of around 97% but this needs to be considered. If the staff in your organization is sent 1000 emails per day then this will mean that there are 30 spam emails getting past your security measures every day. All it will take to result in your company being infiltrated will be for one member of staff to do something incorrect in relation to one of these emails.
