Hackers abhor a vacuum. While there are a handful of proven strategies and common-sense policies that organizations need to adopt to begin to gain the upper hand on email hacks, actions are by their very nature reactive, chewing up precious time as bad actors go about their mischief.
The fact is, the user community has let its guard down…if it was ever even up. Still, there are three accessible, cost-effective email authentication tactics for the taking. Users simply need to deploy them.
- SPF Records
A Sender Policy Framework (SPF) record identifies legitimate mail servers – those that are allowed to send email on behalf of your domain. Adding an SPF TXT record detects and prevents spammers from sending messages with forged “From” addresses on your domain. It’s basic and, increasingly, is becoming a requirement for anti-spam filters.
- DKIM Signatures
DKIM (DomainKeys Identified Mail) Signatures permit senders to associate a domain name with an email message, essentially affirming its authenticity. A sender creates the DKIM by “signing” the email with a digital signature, which is located in the message’s header. Like SPF records, DKIM signatures are a snap to add.
- Personal Digital Certificates
Think of a Digital Certificate as an electronic “password” that enables an individual or an organization to exchange data securely over the Internet using the public key infrastructure (PKI). As with the other two methodologies, the cost of deployment is low.
There is no better time than right now to verify that you’re adhering to cybersecurity best practices and procedures. Deploy the above strategies and give yourself the protection you need to ensure your company is able to continue business undisrupted.
