It is a fast-paced world where things change at lightning speed. We have witnessed this trend in almost all spheres of life. This revolution is the engine behind the robust Learning Management System (LMS). LMS has gained extreme relevance and popularity, which has led to a general rise in the global e-learning market size. According to a projection by Statista, the e-learning market size will grow to 400 billion U.S. dollars by 2026, with LMS generating roughly 18 billion U.S. dollars in the same year.

A look at such figures tells you how lucrative the LMS industry is. From the onset, this might look like a great thing. However, the fact that LMS is a lucrative spot makes it a number one target for hackers. Moreover, that brings us to our primary focus- LMS security. Ask yourself this question: “Is my LMS secure? LMS systems hold huge bundles of sensitive data that hackers seek to compromise and use for nefarious purposes. Even more challenging is that most LMS systems are cloud-based, presenting new and urgent LMS security challenges. To that extent, security becomes a critical factor for an LMS.

LMS Security Features For Better Security

Do not panic. Although LMS security vulnerabilities exist, there are several LMS security features you can initiate to safeguard your learning management system. These features and security measures are discussed herein.

• Mobile Security

People (learners, to be precise) prefer using mobile devices to access the LMS. This prevalence in LMS mobility increases the number of vulnerable endpoints and threats. Several types of mobile-related security threats will target your LMS system. They include social engineering, data leakages via malicious apps, unsecured public WiFi, end-to-end encryption gaps, spyware, and many others.

A sound LMS system should have mobile security features to accommodate mobile users’ security. These features should apply to both mobile websites and apps. Here are some of the LMS security features you can have for the mobile version of your LMS system.

• Keep idle screens locked
• Regularly update your phone’s software
• Only download LMS systems, software, and extensions from trustworthy sources
• Use antivirus software on your phone
• Use a virtual private network, especially when using public WiFi
• Avoid jailbreaking or rooting your phone

• Authenticated by 2-step verification 

The 2-step authentication is one of LMS’s most crucial yet disregarded security features. According to Google’s account authentication and best practices report, multiple-step authentication provides 100% protection against automated cyberattacks. The two-step authentication ensures that only authorized users access the learning management system. Once users input their login credentials (usernames and passwords), the system will require them to prove their identity further.

There are various two-factor authentication forms, such as secret codes, biometric authentications, and one-time passwords. For enhanced LMS security, it is wise that you initiate these factors. With 2FA, even when a hacker bypasses your passwords, they will still not access your data because they do not have access to the second authentication factor.

• Enable SSL Encryption

No web application security strategy can be completed without the mention of SSL encryption. Your LMS carries lots of sensitive data. In the modern day and age, data is a significant and vital asset and one of the most sought-after elements by attackers. Covering data through encryption makes it impossible for attackers to access, read and decipher the data. Different types of SSL certs are available in the market which is available at low prices. For example, cheap Wildcard SSL, cheap EV SSL certificate, and above all multi-domain SSL, single domain etc. All these SSL certs are designed for specific purposes.

Enabling SSL certificates on your LMS websites turn on HTTPS encryption. All communications on the websites will be concealed and protected from unauthorized access. In layman’s terms, encryption converts plaintext data into an indecipherable format called ciphertext. The ciphertext is like a “scribbled gibberish” that both machines and regular users cannot comprehend. Unless someone has the decryption key, they will not be able to read encrypted data.

Other than for security purposes, having an SSL certificate on your LMS also helps to boost user confidentiality. Most users prefer HTTPS to HTTP websites. According to Google’s Transparency Report, 93.2% of browsing time in Google Chrome was spent on HTTPS websites. SSL certificates also help to increase visibility in search engines. All these elements are for the good of your LMS.

• Single Sign-on system

A single sign-on system is a security approach that requires users to have a single set of credentials across multiple applications.

For instance, users will have to log into their LMS portals using their work emails and passwords instead of remembering new login credentials. This approach is good for the security of your LMS. LMS users using a single domain-specific email address will find this approach beneficial.

• Strong Password

Passwords are indispensable ingredients for any secure network. Most previous data breaches have happened because of poor and weak passwords. For that reason, a good LMS should have complex password requirements. For instance, the system should require users to use a password of less than a specified length. Moreover, it would be good to encourage users to refrain from using passwords across multiple platforms. According to a 2019 Google study, 13% reuse the same password across multiple platforms. This is a dangerous habit. An attacker who lays a hand on the password could compromise all accounts that use the password.

Here are some of the best password practices you should adopt for your learning management system:

• Make it a requirement for users to use long passwords (7 or more characters are ideal)
• Advise users to change their passwords frequently
• Never use similar login credentials across multiple platforms
• Blend different characters when creating your passwords

• The automated backup storage system

No single network or system is wholly immune to security vulnerabilities. It does not matter the number of security measures you take to safeguard your LMS against attackers. Hackers could still bypass all security walls as they have done to even the most secure system. Your LMS is also vulnerable to data loss, system failures, and many other vulnerabilities outside the scope of control.

It is wise to create a robust data backup and restore strategy to cushion yourself from such unexpected events. While at it, ensure you create the backups offsite and on a separate server. It is also wise that you conduct frequent checks and tests on your data backup and restoration plan to ensure that data is stored correctly and that it can be easily retrieved in things go haywire. Lastly, we highly recommend that you frequently back up your data on the LMS. Once or twice a week is good.

• Individual user, roles & permissions

Some of the most devastating security breaches that could hit your LMS are brewed from within your organization. According to the 2022 Ponemon Cost of Insider Threats Global Report, there has been a 44% rise in insider threats. The same report further states that an insider attack’s average cost is $15.38 million.

The best way to deal with insider attacks is to define the user roles and permissions. For instance, regular learners enrolled for training should have minimal access inside the platform to system administrators. Granting regular learners administrative rights will lead them to do all sorts of wrongs, such as grading themselves and awarding good grades.

• Use an Antivirus software system.

Malware, such as viruses, could corrupt sensitive data inside the LMS UX. There is no better way of protecting your learning management system against viruses than using antivirus software. The antivirus software will automatically and frequently scan your LMS to check and stop any form of viruses that might want to eat into your learning management system and its data.

• Must have an IP Blocker

IP blockers prevent hostile IP addresses from accessing your data. With an IP blocker, the system admin can list IP addresses that are allowed to access your system and those not allowed to access. Doing so ensures that malicious virtual attackers cannot access your LMS to view data without permission.

Conclusion

LMS, like all other internet systems, is vulnerable to cyber-attacks. It knows the best LMS security measures to initiate to protect your system against attackers. This article has explored nine security features of LMS that will help boost the security of learning management systems. As a best practice, always ensure you use multiple measures for utmost security

What Are Reverse Proxy Servers And Why Use Them For WordPress

A reverse proxy server retrieves resources from one or more servers on behalf of a client. These resources are then delivered to the client without a way to tell that they originated from the proxy server.

Reverse proxies are useful because they can hide the existence and characteristics of the originating server. For example, a reverse proxy can provide an extra layer of security, performance, and reliability for web applications by shielding them from malicious requests or large amounts of traffic.

If you’re curious to learn more, there are many resources online to help you learn more about reverse proxy servers. There are several common reasons why setting up a reverse proxy server might be necessary:

• Improved site performance with content caching

A common use case for a reverse proxy is to cache frequently requested WordPress content. For example, if a group of web servers serves a website, a reverse proxy can cache the website’s static content (such as HTML pages, images, and CSS files) on a single server. This can improve the WordPress website’s performance, as the content does not need to be retrieved from the web servers each time a user requests a page.

• Offloading CPU-intensive tasks such as image resizing

A reverse proxy server can offload CPU-intensive tasks such as image resizing from the WordPress server by forwarding requests for these tasks to a server that is better equipped to handle them. This can help improve the performance of the WordPress site by freeing up resources on the WordPress server for other tasks.

• Improved security by filtering requests and blocking malicious traffic

A reverse proxy server can improve WordPress security by filtering requests and blocking malicious traffic. By filtering requests, the reverse proxy server can block access to specific IP addresses or regions that are known to be associated with malicious activity. By blocking malicious traffic, the reverse proxy server can help DDos mitigation and other attacks that target WordPress sites.

• Making WordPress accessible from a different domain or subdomain

As mentioned above, reverse proxy server retrieves resources from one or more servers on behalf of a client. These resources can be any file type but are most commonly web pages. The reverse proxy server then provides the client with these resources and they appear as if they originated from the server itself. This is done by configuring the reverse proxy server to forward requests for WordPress content to the WordPress server while still giving the client the illusion that they are accessing the content directly from the local proxy server.

Most Popular Reverse Proxy Servers

According to W3Techs, around 83% of websites do not employ a reverse proxy service. The remaining 17% that do are mostly CDNs, as reverse proxies generally conceal their presence for security purposes, making it difficult for website monitoring services such as W3Techs to determine which ones are the most widely used. Here are the three most commonly used reverse proxy solutions:

• NGINX

NGINX is a web server that offers multiple advantages, such as enhanced performance, safety, dependability, and scalability. You can get it for free or use the commercial edition, NGINX Plus, for corporate websites with API-based setup possibilities. Quite a few big businesses use NGINX – Cloudflare, Netflix, MaxCDN, among others. Configuring NGINX as a reverse proxy is easy, and you can personalize it to satisfy your needs.

• Varnish

Varnish is a type of open-source software that can improve the performance of high-traffic websites. It works as a reverse proxy, load balancer, web application firewall, and edge authentication server, and it supports Edge Side Includes (ESI) for faster page loading. You can use it as a front-end for NGINX or Apache web servers, or set it up as a reverse proxy for WordPress.

• Apache Traffic Server

Apache Traffic Server, an open-source option renowned for its performance and capacity, was first developed by Yahoo! as a commercial service before they gave it away to the Apache Foundation. It is currently being used by many content networks and CDNs, including Akami, Apple, Comcast, LinkedIn, and Yahoo to enhance their systems. In addition, Apache HTTP Server (Apache httpd) can be employed to set up a reverse proxy on your web server that allows it to supply both static and dynamic content to users while still operating as a regular web server.

• HAproxy

HAProxy is a free, open-source reverse proxy and load balancer designed to work with many existing web server architectures, such as Linux systems and cloud-based platforms. It utilizes an event-driven I/O model and can distribute requests across multiple worker processes, similar to NGINX. HAProxy is renowned for its capacity to handle large traffic volumes even during peak loads. It is used by some of the largest sites in the world, such as Airbnb, Reddit, and Instagram.

Reverse Proxy Server Use Cases For WordPress Sites

Although you can also use other reverse proxies, NGINX is the most popular choice. Here are the three main use cases for setting up a reverse proxy for WordPress sites:

• Main and proxy website on a single server

If you have both the main and proxied sites hosted on the same web server, you can set up a reverse proxy so that the proxied site loads from the main site. You can do this by configuring all relevant reverse proxy rules on the main site and setting up the proxied site to load through the proxy. In addition, if using an SSL certificate, specific rules must be in place in the wp-config.php to prevent redirection loops. Note that it is impossible to create a URL with the same subdirectory as the one used to load the site.

• Hosting only the proxied site on your server

To create a reverse proxy, you must contact the server admin of the main website and configure the rules on two servers. A domain name that points to the reverse proxy should also be added. This is usually done via a subdomain (e.g. blog.your_domain.com) that is linked to the proxied site (e.g. your_domain.com/blog). Note that you’ll need the IP address from the server to complete the setup process.

• Main site hosted on your server

If you can only access the main website and its hosting server, then you should set up a reverse proxy and adjust its settings so that the page is pulled from an external host. It will be the responsibility of the administrator of the secondary server to install and configure the proxied site to be accessed through the reverse proxy.

Steps To Set Up A Reverse Proxy For WordPress

Setting up a reverse proxy for WordPress is a great way to improve your website’s performance. It can also help protect your web server from malicious requests and help improve user experience. Below are the steps you need to take to set up a reverse proxy for WordPress.

1. Install a reverse proxy server

The first step is to install a reverse proxy server. We recommend using the NGINX web server, which is free and open source. Other popular web servers, such as Apache, can also be used, but we’ll assume you’re using NGINX for this tutorial. Let’s say you want to use a NGINX reverse proxy (192.x.x.10) along with an Apache web server (192.x.x.20) which is already up and running.

Installing NGINX on a Ubuntu server is a matter of running a single command:

sudo apt-get update
sudo apt-get install nginx

Once NGINX is installed, use this command to disable the virtual host:

sudo unlink /etc/nginx/sites-enabled/default

Now it’s time to create a reverse proxy. You can do that by creating a file called reverse-proxy.conf in the etc/nginx/sites-available directory. First of all, navigate to the directory:

cd etc/nginx/sites-available

Create the file via the vi editor:

vi reverse-proxy.conf

Add the following lines to the file:

server {
listen 80;
location / {
proxy_pass http://192.x.x.20;
}
}

As we can see, the proxy pass is allowing requests coming through the reverse proxy to be passed along to 192.x.x.20:80, the main server’s remote socket. In other words, both servers share the content. Once you’re done, save the file and exit the editor. To forward information to other servers, use the ngx_http_proxy_module in the terminal. Finally, you need to activate the directives by linking to /sites-enabled/ with this command:

sudo ln -s /etc/nginx/sites-available/reverse-proxy.conf /etc/nginx/sites-enabled/reverse-proxy.conf

All that’s left to do is testing the reverse proxy. You need to run a configuration test and restart NGINX to verify its performance. Use the command below to check if NGINX works:

service nginx configtest
service nginx restart

In case the test fails, it means that Apache is probably not set up properly.

Reverse Proxy Server Limitations

A reverse proxy can present a major security risk because it can observe and modify all traffic going through it. If HTTPS traffic is sent via the reverse proxy, then the data must be decrypted and re-encrypted, which requires the private keys of the SSL/TLS certificate. If a hacker gains access to this reverse proxy, they have the potential to log passwords and insert malicious code into websites.

A reverse proxy can create a single point of failure if neither you nor your users can access the main server directly. For example, if one reverse proxy serves multiple domains, any disruption will render all those sites inaccessible. If a third-party reverse proxy is used, don’t forget that you’re sharing important details about the site with them.

Conclusion

Setting up a reverse proxy for WordPress can benefit website security and performance. The steps to set up a reverse proxy for WordPress vary depending on the server and configuration. Generally, they include configuring the proxy server, setting up the backend web server, and setting up the WordPress site. Although setting up a reverse proxy server can be beneficial, it has limitations.
