Amid domain hijackings, the DHS has issued a directive urging US government departments to lock down their domain name settings for official web addresses. The directive was issued after Homeland Security’s Cybersecurity and Infrastructure Security Agency (CISA) were alerted to hackers successfully tampering with the Domain Name System (DNS) infrastructure.
Government employees have been urged to use strong passwords for DNS settings and multi-factor authentication to prevent unauthorised access. Domain hijacking can allow hackers to gain access to account passwords through which they can change name services, domain and sub-domain records.
