Nevertheless, given its ubiquity, DNS can also play an critical purpose in securing corporations — specifically shielding distant workers and info and software site visitors, EfficientIP reported.
50 % of those surveyed mentioned they use DNS targeted traffic investigation to detect compromised devices, and a quarter 27% send DNS targeted visitors logs to SIEM platforms for assessment.
“While it is beneficial that corporations want to use DNS to secure their progressively distant workforces, companies are continuing to endure the high-priced impacts of DNS attacks,” claimed Romain Fouchereau, exploration supervisor for European security at IDC.
