How to / how to secure CentOS server using CWP features
« on: June 29, 2014, 07:43:20 AM »
how to secure CentOS server using CWP features

1. Enable CSF Firewall (in CWP.root in security menu you have CSF Firewall)
2. Change SSH port
3. Enable ModSecurity with OWASP security rules
4. Use only random generated passwords


How to enable CSF Firewall
In your CWP menu go to Security --> CSF Firewall and click on firewall enable



How to change SSH port
In your CWP menu go to Services Config --> SSH Configuration
now replace #22 with eg. 8404 and restart ssh server on index page of the CWP

You will need to add this port also in CSF Firewall
1. go to Security --> CSF Firewall --> Firewall Configuration
2. replace TCP_IN and TCP_OUT port 22 with your port
3. restart CSF Firewall

cut from configuration
Code: [Select]
# Allow incoming TCP ports
TCP_IN = "20,21,22,25,53,80,110,143,443,465,587,993,995,2030,2031"

# Allow outgoing TCP ports
TCP_OUT = "20,21,22,25,53,80,110,113,443,2030,2031"



How to Install ModSecurity with OWASP security rules
In your CWP menu go to Security --> Mod Security and click on Install Mod Security



Use only random generated passwords
One of the most important things is to ALWAYS use random generated passwords with length 8+ characters.
CWP also has built in random password generator which will generate random password for each new account on creation.

One of best tools for that is here:
https://www.random.org/passwords/

Random passwords needs to be used for all public services like:
 - CMS applications like Wordpress admin user
 - FTP Passwords
 - Email Account Passwords
 - Account passwords
... and any other available on the internet

PHP / suPHP - 500 Internal Server Error
« on: June 13, 2014, 03:26:53 PM »
This error  is usually related to a permissions/ownership issue.
suPHP requires that the files are owned by the user name. Permissions on php files should also be set to 644 (-rw-r-r-), folder permission must be 755.

How to change ownership on the files and folders

Quote
option no.1. (this will fix all permissions for the user account)
go to CWP menu --> User Accounts -- > Fix Permissions and select user

option no.2.
For one file eg. /home/test/public_html/index.php
Code: [Select]
chown USERNAME:USERNAME /home/test/public_html/index.php
For all files in /home/test/public_html folder (RECOMMENDED)
Code: [Select]
chown -R USERNAME:USERNAME /home/test/public_html/*


How to change permissions on the files and folders

For one file eg. /home/test/public_html/index.php
Code: [Select]
chmod 644 /home/test/public_html/index.php
For all files in /home/test/public_html folder (RECOMMENDED)
Code: [Select]
cd /home/test/public_html
find . -type f -exec chmod 644 {} \;


If not of the above helps than you can check .htaccess file
you can check, disable, rename .htaccess file as rules inside this file can cause this issue.

You can also tail/monitor error log using command
Code: [Select]
tail -f /usr/local/apache/logs/error_log

Please remember that shoutcast servers use 2 ports always

If you have enabled CSF Firewall you will need to open shoutcast port and port +1.
