How to protect your business from phishing
A big part of protecting your business, employees, and customers from phishing attacks is using industry standards and implementing best practices where possible. Standards such as the Sender Policy Framework (SPF), DomainKeys Identified Mail (DKIM), and Domain-based Message Authentication, Reporting, and Conformance (DMARC) are all aimed at combating the spread of SPAM by allowing receiving servers to verify the servers they are accessing. mail from. Put another way, the goal of these standards is to ensure that the mail servers that claim to send on behalf of your domain are authorized to do so. Each of these standards is based on DNS and is easy to use.
In fact, you probably get your email through a service provider like Google or Microsoft, and that service includes the latest implementation of these standards. Professional email services like these offer some degree of protection against phishing, but they are far from perfect, leaving the market for these services wide open.
A major form of attack is aimed at stealing information through low-level means such as email replies. Tools such as content policies found in enterprise productivity services such as Microsoft 365, Google Workspace, and even as a third-party tool from multiple vendors, are essential in preventing this type of attack from reaching a successful conclusion. Content policies help automate the identification of types of sensitive information such as credit card or bank account numbers, social security numbers, and other information that should be closely guarded, and prevent this information from being sent outside the organization.
