Secure Permissions for Default Database File Path (DFTDBPATH)

MediaNivel 1Automatizadadb2

Descripción

The DFTDBPATH parameter contains the default file path used to create Db2 databases. It is recommended that the permissions for this directory be set to full access for Db2 administrators and read and execute access only for all other accounts. It is also recommended that this directory be owned by the Db2 Administrator. Automated as: the DFTDBPATH directory is not group- or world-writable (755 or stricter); verify ownership by the Db2 administrator separately. Run as the instance owner (or with sqllib/db2profile sourced) so the db2 CLP reads this instance's configuration.

Cómo se verifica

Método de auditoría: Comando de shell

shell
out=$(db2 get dbm cfg 2>/dev/null) || exit 1; p=$(printf '%s\n' "$out" | sed -n 's/.*(DFTDBPATH) *= *//p' | sed 's/[[:space:]]*$//'); [ -n "$p" ] || { echo compliant; exit 0; }; [ -e "$p" ] || { echo "noncompliant: $p does not exist"; exit 0; }; w=$(find "$p" -prune \( -perm -020 -o -perm -002 \) -print); [ -z "$w" ] && echo compliant || echo "noncompliant: $p is group/world writable"
Salida esperada
compliant

Cómo se corrige

Método de corrección: Guía o parche de infraestructura

For Windows and Linux: 1. Attach to the Db2 instance. db2 => attach to <db2instance> 2. Run the following command to change the default file path, if necessary: db2 => update database manager configuration using dftdbpath <valid directory> Additional steps for Windows: 1. Connect to the Db2 host 2. Right-click over the directory used as the default file path 3. Choose Properties 4. Select the Security tab 5. Assign ownership of the directory to the Db2 Administrator 6. Grant all Db2 administrator accounts the Full Control authority 7. Grant only read and execute privileges to all other users (revoke all other privileges) Additional steps for Linux: 1. Connect to the Db2 host 2. Change to the directory used as the default file path 3. Assign the Db2 Administrator to be the owner of the directory using the chown command 4. Change the permissions for the directory $ chmod -R 755
