Why is wired technology safer than wireless technology?

Wireless technologies, such as Wi-Fi and Bluetooth, have brought about major advancements in improving the convenience and flexibility of the electronic devices we use every day.

Thanks to their ability to connect quickly and easily without cables, these technologies have made devices such as Bluetooth headphones, smart speakers, mobile phones, and laptops more versatile in terms of connectivity and interaction.

Newer Wi-Fi standards like Wi-Fi 6/6E or Wi-Fi 7 even improve data transfer speeds and the ability to connect more devices simultaneously, while Bluetooth technology saves energy and extends the battery life of mobile devices.

However, compared to wireless connections, wired connections still offer significant advantages, especially in terms of security. One of the key factors that makes wired connections preferred in high-security environments is their stability and resistance to intrusion.

With wireless connections, signals can be easily interfered with or stolen without robust security measures, as signals travel through open space. Conversely, wired connections create a physical link, limiting the risk of external intrusion and are generally less susceptible to remote attacks.

Furthermore, wired connections do not rely on radio waves, thus eliminating the risk of attacks from methods such as man-in-the-middle attacks or signal jamming.

Therefore, although wireless technology offers undeniable convenience, when it comes to stringent security and stability requirements, wired connections are still considered the superior choice.

1. There is no radio signal for hackers to attack.

Wireless networks transmit data via radio waves, allowing signals to propagate widely within a local area and often transcend physical boundaries, potentially reaching neighboring areas such as adjacent apartments or nearby streets.

This very "openness," while offering convenience and flexible connectivity, makes wireless networks easy targets for attacks such as:

Eavesdropping:Hackers can use readily available tools, such as Wi-Fi signal analysis software, to intercept and monitor transmitted data packets. This allows them to collect sensitive information, including passwords, login credentials, and users' personal data, without being detected.

Man-in-the-middle attack:An attacker can intercept the communication between two devices, gain control, and interfere with the data being transmitted, thereby blocking or altering information without anyone knowing.

Fake access point:Devices of unknown origin can impersonate legitimate Wi-Fi access points, tricking users into connecting to them and thereby collecting sensitive user information.

Conversely, wired connections transmit data through physical cables, such as Ethernet, providing direct control over where data travels. This control eliminates the possibility of remote attacks, ensuring a superior level of security and far greater safety compared to wireless connections.

2. Wired connection attacks require physical access to the devices.

Because there are no radio signals to interfere with, hackers would need physical access to cables and equipment to infiltrate your network. This difference acts as a strong layer of protection, forcing attackers to overcome a series of challenges:

Physical connection:To infiltrate the network, an attacker must connect their device directly to the system, requesting access to Ethernet ports, USB ports, or other physical interfaces.

Hardware deployment:Hackers would have to use specialized hardware hacking tools, a costly and complex method. Many of these tools are expensive and sometimes not worth the expense, making the intrusion less feasible.

Time constraints:If hackers have physical access to the devices, they will have to act quickly to avoid detection, as the risk of detection increases. This time pressure creates a major obstacle, making it much more difficult to infiltrate and exploit your network.

These physical barriers pose a significant challenge, considerably increasing the effort, time, and risk faced by attackers. Furthermore, households and organizations often implement additional security measures such as surveillance camera systems, intrusion detection software, and restricted access protocols, making network penetration far more difficult and complex for hackers.

3. Using unauthorized hardware is easier to detect.

Using unauthorized hardware to connect to a wired network is often easier to detect than infiltrating a wireless network. Unlike wireless attacks, which leave no physical trace, hardware attacks involving specific devices can be easily identified and neutralized. For example:

Network eavesdropping or analysis devices:These devices are directly connected to the network and are capable of intercepting data being transmitted. However, because they require a physical connection, they are easily detected and quickly removed.

Hazardous devices:Unauthorized computers or peripherals, such as USB keyloggers, must be physically connected to network devices, which facilitates their rapid detection and removal.

Although more sophisticated wired network intrusion devices are now available on the market, such as OMG cables, which look like ordinary USB charging cables, they actually incorporate network attack features.

Although these types of cables are harder to detect, they are very expensive and are often used to attack large organizations rather than ordinary households.

4. No need to adjust or change security settings.

Wireless networks typically require precise configuration to ensure secure data transmission. However, if improperly set up, network devices and other wireless equipment can become easy targets for hackers' tracking tools, creating serious security vulnerabilities.

Conversely, wired networks are far more stable and secure, with a significantly lower risk of misconfiguration. When using a wired connection, you won't need to worry about:

Weak or outdated encryption protocol:Older encryption standards like WEP (Wired Equivalent Privacy) are easily exploited and cracked by hackers. Meanwhile, more modern protocols like WPA3 (Wi-Fi Protected Access 3) offer a higher level of security, but only when implemented and configured correctly.

Default authentication information:Many wireless routers and security cameras are pre-configured by the manufacturer with default usernames and passwords. If this information is not changed, it becomes a vulnerability that hackers can easily exploit. Using search engines or automated attack software, malicious actors can easily access and exploit these devices.

Open access points:Unsecured wireless networks can become a wide-open gateway for unauthorized users to infiltrate, creating a high risk of data theft and serious security breaches.

Not using radio signals in wired networks significantly reduces reliance on complex software configurations for basic security. This simplicity eliminates many of the risks commonly associated with misconfigurations in wireless networks, making wired networks inherently more secure, even if users make mistakes.

Wireless technology offers superior convenience, but wired connections stand out for their high level of security thanks to their inherent characteristics. However, this doesn't mean you should completely abandon wireless technology.

By ensuring proper configuration of wireless devices, limiting the number of smart home and IoT devices to necessary levels, and paying attention to setting up a secure local network, a combination of wired and wireless devices will adequately meet the security requirements of most households.
