Is Screen Mirroring Safe? Screen Mirroring & Casting Differences

 a What is screen mirroring? Is it any different from screencasting and screen sharing? Is screen mirroring safe? In today’s era of modern technology, streaming or watching movies has advanced far beyond compared to the previous years. Right now, screen mirroring is one of the not-so-latest advancements.

Is Screen Mirroring Safe

However, it’s still pretty popular among movie enthusiasts and used for larger-scale purposes at universities, offices, or schools. But is screen mirroring as safe as using it? In this guide, we’ll cover all you need to know about it. We’ll talk about the differences in duplicating or media casting technologies, whether they are safe to use, and how to use them. We’ve even discussed ways you can secure your devices and data while screen mirroring content.

What is media casting or mirroring?

Media Casting is a feature that some streaming devices offer, allowing you to cast, screen, or reflect content from one device onto a TV screen. The most common kind of media casting feature is screen mirroring. Other types of media casting features include screencasting and screen sharing. 

All media casting devices have a feature that allows you to display or cast a movie, a screen, or even an app from your mobile phone, tablet, or PC onto your Smart TV screen. The point of casting is to get more significant replications onto your TV than what’s displayed on the casting device. For instance, you can cast or mirror some dance videos on YouTube from your phone to your Firestick device.

Even though there are different techniques for media casting, they’re slightly different from each other, with the nearest similarities seen with mirroring and casting. Screen mirroring means exact replications. It’s like looking into the mirror; the exact background, images, and movements are seen. It works by mirroring content from a smaller device onto your TV screen. 

On the other hand, screen casting only displays the app you select. You can screencast a movie from an app on your phone, and the visuals and audio are seen on a larger screen, like a cinema casting device. 

What is screen mirroring?

As mentioned above, screen mirroring is a technology or feature on your device that lets you use a phone, laptop, tablet, or desktop computer to wirelessly reflect the exact screen of that device onto your TV. 

You can use mirror screening to project a copy of your homepage, a screen saver, a movie, or a game presentation of one device to another, and it’ll appear precisely the same. This feature is mainly used for presentations, assignments, meetings, seminars, and more.

It is used so that a larger audience can see content altogether. It could also be used for movies and photo slideshows, but that mainly falls into the category of screen casting. Even though screen mirroring has many practical usages, is it safe? 

What is the difference between screen mirroring, screencasting, and screen sharing?

As mentioned above, screen mirroring and screen cast are similar but different. Another third part of media casting is screen sharing, similar to but not exactly the same as screen mirroring. Either way, we’ve given you a brief description below of their differences. They are: 

  • Screen mirroring: means reflecting a complete copy of your screen onto another device. In short, share the exact mirror image of your screen from device A and reflect it to device B. The mirroring is done simultaneously in the same room, same connection and devices that are compatible.
  • Screen casting: if you break the words, it’s easier to understand. Basically translates to casting or projecting the content of one device onto a larger display. In most cases, it allows you to selectly cast the content of selected apps from your phone to a Smart TV display.
  • Screen sharing: this is similar to screen mirroring, but the devices need to be compatible with each other. 

Screen mirroring has its benefits and is used to heighten visual experiences, but is screen mirroring safe? 

Is screen mirroring safe?

Screen mirroring came into the picture when HDMI cables were slightly over the budget and out of style. The price of putting cables through the walls or ceiling, even though safe, can cost a lot when damaged. The best solution to outdated HDMI cables is screen mirroring, where no manual connections are required. You only need a good internet connection, two devices, and the screen mirroring option. 

However, security risks are found in the most unexpected places. Both devices can be compromised if your network or system is not secure. That said, screen mirroring is safe only if you take active preventive measures against compromisation. Primarily speaking, there are three kinds of screen mirroring risks that you should bring into your focus: 

  • Transmitter and Receiver – Unprotected access 
  • Risks in Corporate network security 
  • Scarcity of data and device security 

Transmitter and Receiver – Unprotected access

Many companies now use screen mirroring technology for official meetings, seminars, and more. However, with that came an increase in security concerns. Companies are now using media-casting devices like Airtame, Miracast, and Mersive that do not come with encryption nor actively promote encryption of data transmitters. This is the kind of data casting that can open room for cyberattacks. Anyone with a target or the right software can infiltrate the connection between the transmitting and receiving devices. 

Risks in Corporate Network Security

Most screen mirroring flaws are detected and targeted at more giant corporations. They utilize screen mirroring presentation solutions built around or connected with the company’s network. Data is transmitted from one official’s device to the receiver attached to the displaying device over a dedicated network. This could cause some threats over the network that lead to password compromisation, malware attacks, and other kinds of threats. 

Scarcity of Data and Device Security

Whether you’re using a screen mirroring device or use the feature for companies or small-scale needs, there is a lack of security being inculcated. Research shows that the US loses around $16 million yearly only because adequate cybersecurity measures are not added.

Steps to maintain security while screen mirroring

The main target to make screen mirroring safe again is to include protection of your Wi-Fi. Once that is sorted, screen mirroring or casting will be easier and more protected to include. Here’s how to maintain security measures for screen mirroring: 

  • Updates – One way for protection is maintaining device security, including updating them. Devices without new updates cause serious setbacks. This can be your casting device, the receiving device, your router, its firmware, and more. 
  • VPNs – Use cybersecurity software like a VPN. The primary purpose of using a VPN for mirror screening is to add encryption to your connection, device, and data. It shields your IP address and prevents data leaks when connected to personal and public Wi-Fi. You can easily protect your device and data from ISPs and other third parties while screen mirroring. The VPN encryption, on its own, makes things safer and near to impossible for hackers to hijack the mirroring connection between your wireless casting device and your receiving device. 
  • Disable WPS and UPnP – Sometimes, there are things known as de-authentication attacks that arise when WPS and UPnP are enabled. To secure this, disable them and enable the “Encryption of Management Frames” if your router has it. 
  • Strong passwords – You might assume that a strong Wi-Fi password is pointless. It’s just the opposite. Most hacking or intrusion of Wi-Fi networks occurs because of simple WiFi passcodes. Make sure you change them to something more substantial that no one would ever guess. 
  • Prevent public or free Wi-Fi – Never connect to public Wi-Fi for screen mirroring or even screen casting. Most free Wi-Fi networks are unsecure and come with more threats than you need. If a private network is not on hand, use a VPN and connect to external networks.
  • Chane admin network name – Another step is also secure your network by changing the admin credentials. Never stick with the standard. 
  • Secure router SSID – Lastly, never reveal your router’s SSID (Service Set Identifier.) This helps prevent other users from seeing your WiFi ID on a list of networks near them.
