Method # 1. Using launch options

To enable safe mode using the graphical interface, you must press the key combination from: Windows + C to open “Settings”, then click on “Power”. After that, click on Shift and then “Restart”. Click Troubleshoot, then Launch Options. Click “Restart” after “Enable safe mode” is displayed in the displayed list.

Use the arrow keys to enter safe mode. After you press Enter, in safe mode, your Windows Server will boot into unopened mode.

After successful inclusion of safe mode, your background should be black, and in the upper right corner on your desktop will appear the inscription “Safe mode“

Method # 2. Using msconfig

In order to boot into safe mode using the system (msconfig), you must go to Run and run msconfig

On the Download tab, which is located in the Download Options, select Secure Download. Then click “OK”, and the server will automatically restart in safe mode. If you are prompted to “Restart,” click OK.

When loading in safe mode, the background of the desktop will be black, and in the upper right corner of the desktop will appear the inscription “Safe Mode“

Disable and uninstall SELinux

# setenforce 0
# yum remove selinux-policy\*
# rm -rf /etc/selinux/targeted /etc/selinux/config

Install SELinux

# yum install selinux-policy-targeted
# yum install selinux-policy-devel policycoreutils
# touch /.autorelabel; reboot

SELinux will detect the /.autorelabel file upon reboot, and then reconfigure all the files in the correct SELinux contexts. If you have many files in your virtual machine, then VPS may be unavailable for a long time.

Note!

If SELinux is not already installed, then you need to go to step 2 – installing SELinux. If SELinux is installed on your virtual server, then you need to remove it (to reset the policy to the default settings)

Install CSF

First you need to install CSF and disable and stop firewalld. This can be done using the following command:

systemctl disable firewalld
systemctl stop firewalld

Next, you need to install Iptables. This can be done using the following command:

yum -y install iptables-services

Then you need to create files needed by iptables

  touch /etc/sysconfig/iptables
  touch /etc/sysconfig/iptables6

Next, you need to run iptables

systemctl start iptables
systemctl start ip6tables

Then you need to enable iptables at boot

systemctl enable iptables
systemctl enable ip6tables

Install CSF dependencies

yum -y install wget perl unzip net-tools perl-libwww-perl perl-LWP-Protocol-https perl-GDGraph -y

Download and run the CSF installer.

cd /opt
wget https://download.configserver.com/csf.tgz
tar -xzf csf.tgz
cd csf
sh install.sh

Delete the following installation files

rm -rf /opt/csf
rm /opt/csf.tgz

Done. All steps have been successfully completed.

Start your Mongo client first. On Linux, this is the mongo command. Enter this block of text, of course, changing the parts of the placeholder to your own information.

The protection procedure begins with the fact that you need to start your Mongo client. On Linux, this is the mongo command. Enter this block of text, of course, changing the parts of the placeholder to your own information.

db.createUser({
  user: "USERNAME", 
  pwd: "PASSWORD", 
  roles: [
    {
      role: "readWrite",
      db: "YOUR_DATABASE"
    }
  ]
});

Next, you need to exit the mongo client and edit the MongoDB configuration file. Depending on your OS and distribution, you will find it in one of these places.

/etc/mongodb.conf
/etc/mongod.conf

Change the following #security: line to the following:

security:
  authorization: enabled

You should consider changing the bind port to localhost (127.0.0.1) or bind it to a private IP address that is not available on the Internet.

# network interfaces
net:
  port: 27017
  bindIp: 634.234.102.6

You should always watch your spaces! Always two by one, never tabs. After that, restart the MongoDB database.

systemctl restart mongod
systemctl restart mongodb
