Encryption in the PostgreSQL database system
Pavlíček, Michal ; Ilgner, Petr (referee) ; Šeda, Pavel (advisor)
Bakalářská práce se zabývá problematikou šifrování v databázovém systému PostgreSQL. Teoretická část práce detailně vysvětluje základní pojmy spojené s databázemi a šifrováním, dat mimo využití a dat přenášených po síti. Popisuje frekventovaně využívaných šifrovacích algoritmů, je vysvětlena problematika typů klíčů a jejich managementu. Analyzovány jsou bezpečnostní funkce pěti hlavních databázových systémů. Praktická část práce zahrnuje implementaci tří nástrojů pro nastavení transparentního šifrování v PostgreSQL a jejich popis. Bylo zjištěno, že PostgreSQL neposkytuje možnost transparentního šifrování na úrovni databáze, ale lze ji šifrovat na úrovni souborového systému nebo pomocí modulu pgcrypto na úrovni sloupců v relační tabulce. Měření výkonu ukázalo, že transparentní šifrování na úrovni databáze dosahuje v průměru lepšího výkonu i zabezpečení než šifrování souborového systému, ačkoli jednotné nastavení konfigurace může ovlivnit výkon šifrování. Práce přináší ucelený pohled na problematiku šifrování v PostgreSQL a poskytuje relevantní informace pro rozhodování v oblasti databázové bezpečnosti.
