12 한국의대표적인개인정보침해사례 개인정보침해사례 리니지게임 H 자동차 S 및 K 신용정보사 G 홈페이지제작사 관리체계부실로인한대량개인정보유출사건 G 홈페이지제작사관리체계부실로인한대량개인정보유출사건 대량명의도용사건 : 남의명의를도용하여게임작업장운영하다적발됨 개인정보를취급하는전직장에서근무하면서빼낸개인정보를범행에사용 서비스센터 ( 직영및업무협약 ) 에 IP 와비밀번호를부여해담당책임자없이직원아무나자사전산망에서고객의정보를조회할수있도록방치했던것으로드러났다. 최모씨는 H 자동차서비스센터에근무하면서알게된 ID 와비밀번호를이용해 H 자동차전산망에접속하는방식으로 10 만여건의고객정보를쉽게빼냈다. 무자격자에게채권추심을위탁하면서이들이함부로신용정보를열람할수있도록방치했다. 이결과채무자등신용정보 10 만여건이유출됐다. G 홈페이지제작사김모이사의경우, 해당제작사가모방송국을포함해수백여개의기업홈페이지를제작, 관리하는업체로, 직원누구나각기업의관리자권한이있다는허점을악용했다. 이를통해김모씨는 1 만여명의고객정보를 400 만원을받고게임작업장운영자에게넘겼다. 국내초고속인터넷가입자의 60% 가넘는 771 만명의초고속인터넷가입자들의개인정보가정작서비스운영자들의관리체계부실로대량유출되는사건이발생해충격을줬다. 경찰은이번수사를계기로앞으로개인정보보호차원에서게임사의개인정보유출방지와대량의개인정보취급업체의정보유출방지대책을강구토록촉구한다는계획이다. * Source:

25 New Concept for Powerful Security Realms make it easy to restrict users with powerful DBA privileges to specified application schemas Separation of Duty -Easy to create an HR dba or Financials dba Factors extend access beyond User and Role based Access Rules control database access based on factors in the environment - Control access based on time of day, IP address, location

26 Factor Network Domain A Firewall Domain = Network A when: DB Hostname in (DB-1, DB-2) and DB Host IP in ( , ) and DB Instance in (CMD05, CNTL06) Network Domain B Firewall Domain = Network B when: DB Hostname in (DB-1, DB-2) and DB Host IP in ( , ) and DB Instance in (SHIP8, SHORE7) Multi-factored Approach

27 Rules & Factors Financials Rule 1: Fin. App from office= All Privileges Rule 2: Off hours = Read, Insert OE Rule 3: Less secure connectivity = Read Only GL Rules enforce access based on factors Factors can be anything Rules validate all factors before allowing access

28 Command Rules Restrict use of DDL Commands On specific or all objects Based on Rule Set conditions Audit/alert and report on violations via Audit Vault Advantages/Potential Usage Separation of Duties (e.g. DBA cannot manage users. Restrict CREATE USER, ALTER USER commands) Implement Business Procedures (e.g. Cannot issue DDL commands against the operational tables during business hours)

29 Building Trust and Meeting Compliance Financials Realm HR Realm DBA DBA Other Applications Realm DBA OE GL PER BEN OLTP OLAP Separation In Control Power user(dba?) 의권한제거 Adaptable Multi-Factor Security multiple factor에의한접속제한 Realms, command rules, predefined schedule등에의한 Resource access의제한 Protected Schema SYS, DV, Audit Hardened Database Server

30 Defense in Depth using Data Vault Database Authorizations Realms Rules/Factors VPD/OLS Database Authorizations Database Privileges Grant roles/privileges to users/roles DATA VAULT Realms Restrict system privileges to specific users/roles for specific schemas/objects (realms) Control realm and role authorizations DATA VAULT Rules/Factors Further restrict authorized actions based on rules Factors expose security attributes, building blocks VPD/OLS Further restrict access at the record level
