It's crucial for individuals and organisations to take email security seriously, especially given the prevalence of cyber-attacks targeting email communications. Understanding risks to confidentiality, integrity, availability, and compliance is essential.
Security Measures
Organisations can deploy encryption, digital signatures, access controls, and intrusion detection systems to defend against threats.
Common Email Attack Types
Phishing uses social engineering to deceive recipients into revealing login credentials or financial information. Spear-phishing is a more focused version targeting specific individuals. Malware attachments install harmful software when opened. Ransomware locks files and demands payment. Business Email Compromise sees criminals impersonate executives or suppliers requesting fund transfers. Email spoofing makes fraudulent emails appear to come from trusted sources. Man-in-the-middle attacks intercept and redirect communications.
Users should remain cautious when receiving emails, verify senders, and double-check sensitive requests. Seeking help is always a good idea when in doubt — reach IT Evolution's Cyber Security team at helpus@itevolution.co.za.
