Initial Version

How does ActiFend work?

The ActiFend WordPress Plugin sends access events in real time from your web server to ActiFend. These events are processed to detect attacks. Any alerts generated in the process are delivered through the ActiFend Mobile App. More information on what data is collected and how it is used is described below.

How is my email address used for Mobile App Authentication?

On the ActiFend mobile app, when you authenticate through a Google / Facebook / LinkedIn account, ActiFend takes it as proof that the primary email address linked to that account is in your control. When that email address matches the email address you gave at plugin activation time, it is taken as proof that you have administrative control of that website. This linkage forms the basis for ActiFend to show you that website's securiy dashboard in the mobile app.

What data is collected from my website and how is it used?

  1. During registration, your email address and your website meta-data are transmitted to the ActiFend server. These include the server hostname, server public name (FQDN) and server IP address.
  2. During normal operation, your website visitor information such as their IP address, the URL they accessed, referrer and user-agent string are sent to ActiFend server (Security Analytics platform) for attack detection and alert generation.
  3. Initially and later whenever the WP Core / a plugin / a theme is added or updated, their meta data (name and version number) is sent so that any known vulnerabilities can be identified and corresponding security alerts generated.
  4. When a backup is requested through the Mobile App, the website data is compressed, encrypted and uploaded to a secure storage account on ActiFend infrastructure.
  5. When any change is detected in the website content, the change meta data (directory and file names) is sent - so that a SUSPECTED INTRUSION alert can be generated by ActiFend.

NOTE: Any forms data submitted by your visitors to your website through a POST request is NEITHER captured NOR sent by this plugin to any servers in any manner.

What other CMS / Web Platforms does ActiFend support?

At this stage, WordPress is the first and only CMS supported by ActiFend. Support for other platforms is planned for near future.

I run WordPress on an Apache / NGINX Server. Can I use ActiFend without the plugin?

Yes, it is possible to use ActiFend on any Linux web server running Apache/NGINX without a plugin. However, automated defense, backup and recovery features are only available through the WordPress plugin. Windows / IIS Server support is planned for the future.

What is an event (hit / access log entry)?

When a visitor to your web site accesses any page on our web site, your server sends one or more resources (HTML pages, included image files, any javascript / stylesheet files, etc). Each such access to a resource counts as one event.

Will ActiFend stop attackers?

Yes. ActiFend detects and blocks certain types of attacks (e.g., bruteforce login attempts). Attackers are blocked immediately. The blocked attacker list is dynamically managed to ensure that only the most recent (and relevant) entries are retained. This helps in making sure the website performance is not adversely affected while still making it very difficult for attackers to succeed.

Where are the attack alerts?

ActiFend no longer reports unsuccessful attacks and attackers. Profiles of attackers are maintained and used for further attack detection as well as blocking. There are plans to give an on demand / periodic summary of blocked attacks & attackers in one of the future versions.

What are the vulnerability alerts?

ActiFend peridically and non-intrusively checks your website for certain commonly occurring vulnerabilities. These include any use of old versions of WordPress Core, PlugIns and Themes. These vulnerabilities are reported through the ActiFend Mobile App.
