System and Network configuration • Lynis suggests more strict permissions on some system files (FILE-7524) like cron files from 755 to 700

sudo lynis --tests FILE-7524
sudo lynis show details FILE-7524
permissions of file /etc/at.deny are not matching expected value (640 != 600)
permissions of file /etc/crontab are not matching expected value (644 != 600)
permissions of file /etc/ssh/sshd_config are not matching expected value (644 != 600)
permissions of file /etc/cron.d are not matching expected value (755 != 700)
permissions of file /etc/cron.daily are not matching expected value (755 != 700)
permissions of file /etc/cron.hourly are not matching expected value (755 != 700)
permissions of file /etc/cron.weekly are not matching expected value (755 != 700)
permissions of file /etc/cron.monthly are not matching expected value (755 != 700)
Are any of these permission-reducing suggestions valid or dangerous, is it only problem on my end and default Debian (13) has "correct" permissions? My system is upgraded down from Deb. 11. Lynis 3.1.4.
