A virtual private network (VPN) is used to establish a connection between remote users and private networks. These connections, secured by data encryption, allows data to be sent between a device and the network. It is critical to monitor VPN usage to receive alerts before there is a spike in response time and the VPN goes down.

Vpn Monitor Srx

Install this plugin to ensure continued availability of VPN connection across multiple locations and monitor the performance of the network by checking the response time of the URL.

Vpn Monitor free download - VPN Gate Client Plug-in with SoftEther VPN Client, CyberGhost VPN, OkayFreedom VPN, and many more programs. PRTG Network Monitor from Paessler is a VPN traffic monitoring tool that is deft at measuring load, the number of users, and traffic. It is also capable of identifying any suspicious traffic or if there are any lags in the connection.

Performance Metrics

• Status of the VPN
• Status of the URL used
• Response time of the URL
• ISP vendor
• Packet Loss

Prerequisites

Use Two Monitors Vpn

• Our Linux/Windows server monitoring agent should be installed in the VPN network.
• While adding a plugin, the plugin name and its folder name inside the Site24x7 agent should be identical.

Plugin Installation

Linux

• Download and install the latest version of the Site24x7 Linux agent in the network where you plan to run the plugin. If it is installed successfully, you will see a Linux server monitor in the Site24x7 Control Panel. This confirms that the agent is able to communicate with our data center.
• Download the vpn_check.py and the isp.sh files from our GitHub repository.
  wget https://raw.githubusercontent.com/site24x7/plugins/master/vpn_check/vpn_check.py
  wget https://raw.githubusercontent.com/site24x7/plugins/master/vpn_check/isp.sh
• Edit the file 'vpn_check.py' to configure the VPN host and port to be monitored. Configure the URL to be monitored in the field 'URL_BEHIND_VPN' in the file 'vpn_check.py'.
• Create a folder with the name 'vpn_check', under the Site24x7 Linux agent plugin directory '/opt/site24x7/monagent/plugins/' and place the 'vpn_check.py' and 'isp.sh' files under '/opt/site24x7/monagent/plugins/vpn_check/'.

Windows

• Download and install the latest version of the Site24x7 Windows agent in the network where you plan to run the plugin. If it is installed successfully, you will see a Windows server monitor in the Site24x7 Control Panel. This confirms that the agent is able to communicate with our data center.
• Download the vpn_check.py file from our GitHub repository.
• Edit the file 'vpn_check.py' to configure the VPN host and port to be monitored. Configure the URL to be monitored in the field 'URL_BEHIND_VPN' in the file 'vpn_check.py'.
• Create a folder with the name 'vpn_check', under the Site24x7 Windows agent plugin directory - C:Program Files (x86)Site24x7WinAgentmonitoringPlugins and place the 'vpn_check.py' file under 'C:Program Files (x86)Site24x7WinAgentmonitoringPluginsvpn_check'

View Data in the Site24x7 Web Client

1. Log in to Site24x7 and go to Server > Plugins > click on the name of the plugin monitor.
2. You will be able to view the performance charts on the various metrics for your VPN network.

A Virtual Private Network (VPN) is a group of network hosts that can transfer encrypted data between themselves on a Virtual Private Network. The technology creates a safe encrypted connection, usually over public networks such as the internet, that allows remote users and locations such as branch offices, to securely access and share resources. The main benefit is providing an adequate level of security and encryption to safely transmit private data across unprotected networks. Even though modern Virtual Private Networks use advanced encryption to protect data, additional controls should be utilized to protect them from vulnerabilities that might be introduced through other system componoents and configuration weaknesses.

The following is a list of recommended Virtual Private Network monitoring and security controls:

• Use firewalls and Intrusion Detection/Prevention Systems (IDS/IDPS) in order to monitor VPN connections.
• Use anti-malware and personal firewalls on remote clients and servers.
• All VPN connections require authentication.
• Logging enabled and auditing performed on a regular basis in order to detect possible attacks.
• Establish user and administrator security training requirements.
• VPN’s placed within a Demilitarized Zone (DMZ) to isolate them from internal protected networks.
• Split tunneling to allow local internet access on remote hosts should be prohibited.
• Use strong authentication mechanisms to include certificates, smart cards, or tokens.
• Access privileges granted on as-needed basis.
• Use strong alternative authentication mechanisms such as Terminal Access Controller Access Control System (TACACS), and Remote Authentication Dial-In User Service (RADIUS).
• Remote access computers physically secure.
• Use strong industry proven encryption with sufficient key strength to protect confidentiality.

It is important to note that even though Virtual Private Networks provide secure communications over insecure networks, client-side security must also be addressed in order to ensure end-to-end security.
