One of the simplest and least cost prohibitive ways to protect your business’ network from cyberattacks is to utilize an anti-spam cloud based solution.
Anti-spam cloud based solutions add security from all cyber attacks including malware, phishing and ransomware. Set up is extremely simple as this is a SaaS (Software as a Service) solution so you will not have to invest additional funds into having a specialist implement and configure the software, run updates or carry out any maintenance. Once purchased this can be operational in a very short period of time and control will be a multi-level administration portal where you can choose your options for acceptable spam thresholds by user, user-group or company-wide. Other selections you can amend here include email quarantine settings, reports productions and risk identification alerts.
Anti-Spam Cloud Based Solution Processes
- Real Time Blocklists (RBLs) are run so as to react instantly when an email is received from a recognized spam source. System manager set Sender Policy Frameworks and recipient verification tools to block email spoofing and remove emails sent to non-existent business addresses.
- Antivirus software: This will spot malware sent in email attachments. Some also include phishing protection and dangerous URL detection to check links within emails that could be potentially damaging.
- Greylisting: This is when all received email is initially rejected and sent back to its originating mail server with a request to send the email once more. The reason for this is that hackers’ mail servers are typically overloaded and will not see the request to send the mail again. Spam detection rates over 99.9% can be achieved through preventing spam emails from “as-yet-unknown” sources of spam and recognized sources of spam, when anti spam cloud based software is used in tandem with greylisting.
- Whitelists can be established so that a mal address which has been marked as potentially dangerous can be amended when it is seen that this is incorrect.
- Antivirus engines: These are used as they will prevent all known malware from infiltrating your databases. However, they will not prevent zero-day threats – malware that has not yet been identified by AV vendors – from successfully stealing your data. For this reason you need an AV solution that includes sandboxing, a process where suspicious email attachments are placed in the sandbox for further analysis to spot command and control server callbacks and other attacks.
- Outbound Scanning: This is crucial for two reasons, recognizing the attempts of hackers to leverage compromised company email addresses to share malware and phishing emails internally and to clients and other contacts and stopping any member of staff that aims to share spam from their account on purpose. Both of these actions would do untold damages to the organization and must be stopped at all cost.
