We all are having good awareness of server security. Its on going process and we have to harden it as much as we can.
For that, we install cloudlinux, Maldet/ClamAV antivirus, CSF, CpHulk. We configure software and hardware firewall on the cPanel server.
We try to update the OS and other thrid party applications. There are lots of security majors which we have to try to implement.
On shared Cpanel server, we have to perform daily/weekly/monthly security audit to avoid malware / sql injections / cross site scripting and a lot more. But till there are lots of chances to compromise admin panel or database access details through PHPshell.
If you want to catch the malware on the fly, use ConfigServer eXploit Scanner (cxs). Its really helpful for shared hosting server.
Following script will help you to secure your database config files on shared server. It will add one more step to secure your servers. It will set perm 600(rw——-) to all user’s database config file. The files will be, wordpress config file / WHMCS config file / joomla config file etc.
Here is the bash script,
cut -f1 -d: /etc/trueuserowners | while read acctName; do awk -F: ‘$1==”‘”${acctName}”‘”{print $6}’ /etc/passwd; done | while read acctHome; do sed -n -r -e “/^[ \t]*DocumentRoot[ \t]+[‘\”]?${acctHome//\//\\/}/s@[ \t]*DocumentRoot[ \t]+[‘\”]?(.*)[‘\”]?\$@\1@p” /usr/local/apache/conf/httpd.conf | sort | uniq; done | while read baseDir; do
