How remote management works
The technology enables you to manage the WP Cerber plugin, monitor activity, and upgrade plugins on multiple WordPress powered websites from a main WordPress website which is called a master website.
To activate this technology, you need to enable a master mode on the main website and a slave mode on each website you want to connect to the master and manage remotely.
Read more:
Manage multiple WP Cerber instances from one dashboard
A safety note
All access tokens are stored in the databases of the master and slave websites in unencrypted form (plaintext). Store a backup copy of all websites in a safe and trusted place.
Troubleshooting
If you’re unable to get it working, that may be caused by a number of reasons. Enable the diagnostic log on the master and on the slave to obtain more information. You can view the log on the Tools admin page. Here is a list of the most common causes of issues on the slave side.
A security plugin on the slave website is interfering with the WP Cerber plugin
A security directive in the .htaccess file on the slave website is blocking incoming requests as suspicious
A firewall or a proxy service (like Cloudflare) is blocking (filtering out) incoming requests to the slave website
The IP address of the master is locked out or in the Black Access List on the slave website
The slave mode on the remote website has been re-enabled making the security token saved on the master invalid
The IP address of the master website does not match the one set in the slave settings on the remote website
Getting started on the master
To configure the main, master website go to the Cerber.Hub admin page and enable master mode. Once you’ve done this you can add slave websites by using security tokens generated on slaves.
Adding slave websites
To add a slave website to the master, you need to enable the slave mode on the website. Go to the Cerber.Hub admin page and enable the slave mode. During the activation of the slave mode, a unique security access token is generated and saved into the database of the slave. Keep the token secret.
Go to the master website and click the “Add” button on the “My Websites” admin page. Copy the token and paste it in the “Add a salve website” popup window.
Manage websites remotely
Once you’ve added all slave websites on the master you can easily switch between them with a single click in a top navigation menu on the admin bar or by clicking the name of a slave on the “My Websites” master page. Once you’ve switched to a slave website use the plugin menu and admin links the way like you do this normally. To switch back to the master website, click a X icon on the admin bar.
Note: when you’re managing remote website, the color of the admin bar is blue and the left admin menu on the master is dimmed.
Using the malware scanner
To start scanning, click either the Start Quick Scan button or the Start Full Scan button. Do
not close the browser window while the scan is in progress. You may just open a new browser
tab to do something else on the website. Once the scan is finished you can close the window,
the results are stored in the DB until the next scan.
Depending on server performance and the number of files, the Quick scan may take about 3-5
minutes and the Full scan can take about ten minutes or less.
During the scan, the plugin verifies plugins, themes, and WordPress by trying to retrieve
checksum data from wordpress.org. If the integrity data is not available, you can upload an
appropriate source ZIP archive for a plugin or a theme. The plugin will use it to detect
changes in files. You need to do it once, after the first scan.
Read more: Cerber
Security Scanner Settings
Interpreting scan results
The scanner shows you a list of issues and possible actions you can take. If the integrity of
an object has been verified, you see a green mark Verified. If you see the “Integrity data
not found” message, you need to upload a reference ZIP archive by clicking “Resolve issue”.
For all other issues, click on an appropriate issue link. To view the content of a file,
click on its name.
Troubleshooting
If the scanner window stops responding or updating, it usually means the process of scanning on the server is hung. This might happen due to a number of reasons but typically this happens due to a misconfigured server or it’s caused by some hosting limitations. Do the following:
Open the browser console (use F12 key on PC or Cmd + Option + J on Mac) and check it for CERBER ERROR messages
Try to disable scanning the session directory or the temp directory (or both) in the scanner settings
Enable diagnostic logging in the scanner settings and check the log after scanning
Note: The scanner requires the CURL library to be enabled for PHP scripts. Usually, it's enabled by
default.

Scanner & Integrity Checker
What's the Quick Scan?
During the Quick Scan, the scanner verifies the integrity and inspects the code of all files
with executable extensions only.
What's the Full Scan?
During the Full Scan, the scanner verifies the integrity and inspects the content of all
files on the website. All media files are scanned for malicious payload.
Read more: What Cerber Security Scanner scans and detects
Configuring scheduled scans
In the Automated recurring scan schedule section you set up your schedule. Select the desired
frequency of the Quick Scan and specify the time of the Full Scan. By default, all automated
recurring scans are turned off.
The Scan results reporting section is about reporting. Here you can easily and flexibly
configure conditions for generating and sending reports.
The email report will only include issues that match conditions in the Report an issue if any
of the following is true filter. So this setting works as a filter for issues you want to
get in a email report. The report will only be sent if there are issues to report and the
following condition is true.
The second condition is configured with Send email report. The report will be sent if a
selected condition is true. The last option is the most restrictive.
Read more: Automated
recurring scans and email reporting
Automatic cleanup of malware
The plugin can automatically delete malicious and suspicious files. Automatic removal
policies are enforced at the end of every scheduled scan based on its results. The list of
files to be deleted depends on the scanner settings. By default automatic removal is
disabled. It's advised to enable it at least for unattended files and files in the media
uploads folder for files with the High severity risk. The plugin deletes only files that
have malicious or suspicious code payload. All detected malicious and suspicious files are
moved to the quarantine.
Read more:
Automatic cleanup of malware and suspicious files
Deleting files
Usually, you can delete any suspicious or malicious file if it has a checkbox in its row in
the leftmost cell. Before deleting a file, click the issue link in its row to see an
explanation. When you delete a file WP Cerber moves it to a quarantine folder.
Restoring deleted files
If you delete an important file by chance, you can restore the file from the quarantine. To
restore one or more files from within the WordPress dashboard, click the Quarantine tab.
Find the filename in the File column and click Restore in the Action column. The file will
be restored to its original location.
To restore a file manually, you need to use a file manager in your hosting control panel. All
deleted files are stored in a special quarantine folder. The location of the folder is shown
on the Tools / Diagnostic admin page. The original name and location of a deleted file are
saved in a .restore file. It’s a text file. Open it in a browser or a file viewer, find the
filename you need to restore in a list of deleted files and copy the file back to its
location by using the original name and location of the file.
Setting up anti-spam protection
The Cerber anti-spam and bot detection engine is capable to protect virtually any form on a website. It’s a great alternative to reCAPTCHA.
Tested with Caldera Forms, Gravity Forms, Contact Form 7, Ninja Forms, Formidable Forms, Fast Secure Contact Form, Contact Form by WPForms and WooCommerce forms.

How to stop spam form submissions on your WordPress
Configuring exceptions for the anti-spam engine
Usually, you need to specify an exception if you use a plugin or some technology that communicates with your website by submitting forms or sending POST requests programmatically. In this case, Cerber can block these legitimate requests because it recognizes them as generated by bots. This may lead to multiple false positives which you can see on the Activity tab. These entries are marked as Spam form submission denied .
Configuring exceptions for the anti-spam engine
How to set up reCAPTCHA
Before you can start using reCAPTCHA on the website, you have to obtain a Site key and a Secret key on the Google website. To get the keys you have to have Google account.
Register your website and get both keys here: https://www.google.com/recaptcha/admin
Note: If you are going to use an invisible version, you must get and use Site key and a Secret key for the invisible version only.
How to set up reCAPTCHA in details
Why does reCAPTCHA not protect WordPress against bots and brute-force attacks?
What is Drill down IP?
To get extra information like country, company, network info, abuse contact etc. for a specific IP address,
the plugin makes requests to a limited set of external WHOIS servers which are maintained by appropriate
Registry. All Registry are accredited by ICANN, so there are no reasons for security concerns. Retrieved
information isn't storing in the database, but it is caching for up to 24 hours to avoid excessive requests and
get faster response.

What is Cerber Lab?
Cerber Laboratory is a forensic team at Cerber Tech Inc. The team studies and analyzes
patterns of hacker and botnet attacks, malware, vulnerabilities in major plugins and how they are
exploitable on WordPress powered websites.

Plugin for inspecting code of plugins on your site: Plugin Inspector
The Plugin Inspector plugin is an easy way to check plugins installed on your
WordPress and make sure
that plugins does not use deprecated WordPress functions and some unsafe functions like eval,
base64_decode, system, exec etc. Some of those functions may be used to load malicious code (malware)
from the external source directly to the site or WordPress database.
Plugin Inspector allows you to view all the deprecated functions complete with
