The three major mobile carriers increased their investments and workforce in information security last year, following the impact of hacking incidents from the previous year.
According to information security disclosures from the Korea Internet & Security Agency (KISA) on July 1, SK Telecom, KT, and LG Uplus invested a total of 367.5 billion won in information security last year. This represents an increase of about 22% compared to the previous year's total of 301.2 billion won.
Among the three, SK Telecom recorded the largest increase in investment. SK Telecom operates its fixed-line business separately through its subsidiary SK Broadband, and the information security investments for both companies are combined to calculate the total.

This amounts to approximately 6.7% of the total IT investment for the two companies.
KT invested 127.5 billion won in information security last year, about 2% more than the previous year's 125 billion won. This accounts for roughly 6.3% of its total IT investment. LG Uplus increased its information security investment by 16.7% from 82.8 billion won the previous year to 96.6 billion won last year, which is about 7% of its total IT investment.
