Ensure pwd_algorithm is configured

中级别 1自动化aix

说明

Defines the loadable password algorithm used when storing user passwords. A development since AIX 5.1 was the ability to use different password algorithms as defined in /etc/security/pwdalg.cfg. The traditional UNIX password algorithm is crypt, which is a one-way hash function supporting only 8 character passwords. Audit: reads `lssec -f /etc/security/login.cfg -s usw -a pwd_algorithm`.

检查方式

审计方法: Shell 命令

shell

command -v lssec >/dev/null 2>&1 || exit 1; out=$(lssec -f /etc/security/login.cfg -s usw -a pwd_algorithm 2>/dev/null) || exit 1; v=$(printf '%s\n' "$out" | sed -n 's/.*pwd_algorithm=\([^ ]*\).*/\1/p'); if [ "$v" = 'ssha512' ]; then echo compliant; else echo "pwd_algorithm=$v"; fi

预期输出: compliant

修复方式

修复方法: Shell 命令

shell

chsec -f /etc/security/login.cfg -s usw -a pwd_algorithm=ssha512
