Network Security Needed Now More Than Ever
Security and privacy have been fundamental concerns in cybersecurity since the late 1990s. However, with increasing data connectivity and the rapid adoption of emerging technologies, network security has become more critical than ever for organizations of all sizes. As more devices connect to networks, traditional security measures struggle to keep up with the growing complexity of an interconnected world. Research from 2015 suggests that the Internet of Things (IoT) will enable organizations to achieve over 90 percent of their mission-critical objectives, from improving customer experiences to enhancing employee productivity (Baldin, 2019).
Wireless and mobile network security focuses on protecting communication channels between remote users and mobile stations. Most available network security solutions rely on either hardware-based or service-based technologies. These solutions include firewalls, intrusion detection systems, and threat intelligence services, which, when integrated, enhance wireless security. Many companies also offer maintenance and management services for such networks, with some providing these services at no additional cost (Nikolaidis, 2003).
Wireless and Mobile Network Security – Cause for Concern
To accommodate rising demands, enterprises are expanding their cellular network infrastructure. The increasing number of mobile devices has led to the deployment of more network solutions to manage connectivity. However, the growing complexity of these networks, combined with evolving threats such as mobile malware, hacking attempts, and denial-of-service attacks, makes security management increasingly challenging. Additionally, the shift towards cloud computing and Wi-Fi networks has introduced further security concerns.
Increasing mobile network traffic has also impacted enterprise security, says Sameer Manchanda, co-founder and CTO at Armis. New mobile malware is continuously emerging, while older threats are becoming more sophisticated, making it difficult for security teams to effectively protect enterprise networks.
Hacking attempts on wireless networks are on the rise, often executed through compromised mobile devices that exploit vulnerabilities in network security. Attackers gain access to personal data by targeting weaknesses in wireless networks, often infiltrating through local area networks (LANs). To prevent security breaches, companies must implement robust wireless and mobile security measures to safeguard against both external and internal threats. Deploying advanced network security solutions is essential to ensuring the security and reliability of wireless and mobile networks (Valcke, 2016).
Change Default SSID and Password
Leaving the SSID (Service Set Identifier) and password set to their default values significantly weakens wireless network security. For instance, many users do not change their default credentials when registering for a Wi-Fi network at public places like coffee shops. If these details remain unchanged, they can be easily exploited by attackers. Wireless network security is a major concern today, and by default, most routers offer minimal protection against unauthorized access. Many routers assign default SSIDs and passwords that are either predefined or generated automatically for clients. To maintain control over a wireless network, users should always change the SSID and password when setting up a new router or updating an existing one. If left unchanged, these default credentials may expose the network to security risks, reducing user control over their router (Muniyal, 2012).
For users who want to modify their wireless network credentials, contacting the service provider is often an option, as many providers offer router management services. Additionally, users can manually change their SSID and password using the following methods:
Mounting the Wireless Network Router via External Network
Many home and small office (SOHO) users rely on routers provided by their internet service provider. These routers connect to external networks such as the internet, LAN, or Wi-Fi. Users who prefer not to share their wireless network should consider changing the default SSID and password to prevent unauthorized access.
Manually Change the Wireless Network Name
Users can manually modify their wireless network name by logging into the router’s management console. This interface is typically accessible through a web browser by entering the router’s IP address. From there, users can update their SSID, password, and other security settings to enhance network protection.
Scan for Wireless Networks
Many routers come with built-in scanning features that allow users to detect and monitor surrounding wireless networks. These scanners help identify vulnerabilities and track unauthorized devices attempting to connect. Once a new wireless network is detected, users can store scanning results in a database and make necessary security adjustments without accessing the router’s management console.
Use Multiple Password
Using the same password across multiple wireless networks can create security vulnerabilities, as unauthorized users may gain access to an entire system if a single password is compromised. To mitigate this risk, users should assign unique passwords to different network segments. Additionally, default router passwords can be modified through the control panel to further strengthen network security.
Use Strong Encryption
Encryption plays a critical role in wireless and mobile network security by ensuring that data is transmitted securely without exposing sensitive information or encryption keys that could be exploited. Additionally, encryption protects web pages, videos, and other data stored on mobile devices. Strong encryption enhances this security, but it also introduces certain trade-offs, such as increased processing power requirements and potential impacts on network performance. While encryption is vital in securing wireless and mobile communications, it is essential to understand its limitations and privacy implications. In today’s digital landscape, where vast amounts of data flow through mobile networks and Wi-Fi, cybercriminals can also leverage encryption to evade security measures, putting organizations at risk of data breaches and legal liabilities (Yifeng, 2021).
Mobile and Wi-Fi networks rely on strong encryption and authentication protocols to safeguard data transmission. However, they are constantly being targeted by threats such as industrial espionage, hardware-based attacks, and cyber intrusions aimed at connected device management.
The widespread use of mobile devices in professional environments has increased the need for robust security measures. Encryption is the most effective method for securing networks, forming the foundation of a protected digital ecosystem. A properly encrypted network prevents unauthorized access and ensures secure data sharing. By scrambling data, encryption makes it unreadable to anyone except the intended recipient. Only the user with the correct decryption key—secured with a password—can access the encrypted data. This process prevents unauthorized interception, data leakage, and security breaches.
What is Strong Encryption?
Strong encryption refers to the process of encoding data so that it remains secure while being transmitted over a network. When using mobile connections, encryption ensures that only the specific data being sent is protected. This security measure relies on the mobile network, the user’s device, and the encryption protocol chosen by the service provider. Users do not need to manage encryption settings manually, as mobile providers implement encryption protocols by default. While strong encryption enhances privacy and security, it can also introduce slight performance reductions. The increased computational workload required to encrypt and decrypt data may slow down network connections. However, this performance impact is generally minimal and is efficiently handled by mobile providers.
Limitations of Strong Encryption
Despite its advantages, strong encryption presents certain challenges from a network security perspective. One major limitation is that encrypted data cannot be easily distinguished from other users’ data, making network monitoring and security enforcement more complex. To mitigate this, users must implement authentication measures for email, social media accounts, and other shared information. Additionally, verifying every encryption key within a network or device is not always feasible. While encryption is designed to protect individual users’ data, attempting to validate every key would introduce significant system overhead, reducing efficiency. In many cases, this additional complexity may not be justified, highlighting the need for a balanced approach to encryption implementation.
Separate Private Network from Guest Network
Private networks enhance wireless communication by allowing Wi-Fi devices to operate within a dedicated, secure network that shields users’ data from unauthorized access. Organizations can leverage private networks to bolster security for both wireless and mobile communications. Public wireless networks, in contrast, typically employ WPA2 encryption to establish secure connections, ensuring that devices communicate without exposing encryption keys over the public internet. However, many mobile devices lack WPA2 encryption, making them vulnerable to security threats. While some mobile devices offer better security than standard public access points, the absence of robust encryption in many cases leaves users exposed. Private wireless networks offer a safer alternative by extending connectivity while maintaining a separate and protected environment, ensuring sensitive information remains inaccessible to unauthorized users. Organizations can take advantage of private networks to enhance overall security and mitigate the risks associated with shared wireless access (Alam, 2014).
Physical Security – Protected Access
Guest Wi-Fi networks, often managed by IT departments or wireless carriers, are widely used in hotels, convention centers, and other public venues. These networks are frequently congested with multiple users and can be insecure, as hotel employees or system administrators may have access to monitor and manage network traffic. This means that unauthorized users, hackers, or malicious entities can potentially exploit these networks to intercept personal and business information, bypass security controls, access applications, or remotely manipulate network settings. In many cases, guest wireless networks connect directly to the hotel’s main internet infrastructure, creating potential security vulnerabilities. The emergence of 4G/LTE networks has further increased wireless connectivity risks, as mobile traffic can be intercepted or redirected, posing additional security concerns for businesses that cater to long-term guests.
One effective solution is to implement a private network supported by a VPN server, ensuring that guest traffic remains secure and isolated. A VPN-based private network allows guests to connect safely without exposing their data to external threats. Furthermore, guest networks that are directly linked to a hotel’s internal internet network increase the risk of data leaks, which could compromise guests’ sensitive information. Hotels can significantly improve their security infrastructure and enhance guest privacy by deploying dedicated private networks.
To mitigate these risks, businesses must invest in robust, redundant, and secure wireless infrastructure. A key measure involves keeping the guest network completely separate from internal hotel systems to prevent unauthorized access. Implementing a dedicated wireless network for internal operations ensures that security-sensitive data remains isolated from guest traffic. However, creating and maintaining such a separate network can be both costly and time-consuming, making it a challenging but necessary investment for many organizations seeking to enhance security and provide a safer user experience.
Vulnerability Tools
Cellular and public Wi-Fi hotspots are particularly susceptible to cyberattacks and are frequently exploited by criminals or, in some cases, state-sponsored actors employing indirect tactics. This security vulnerability becomes even more significant with the widespread presence of Bluetooth, cellular, and IoT wireless connections (Khurshid, 2025). Attackers can exploit these network weaknesses to deploy various types of malicious code, including sophisticated ransomware and spyware, by taking advantage of security flaws in embedded operating systems on mobile devices and smart routers. These vulnerabilities affect routers and network devices manufactured by major companies such as Broadcom, Cisco, Arris, Ericsson, and Huawei. In addition to targeting routers, attackers can extend their reach to other access points, including Wi-Fi hotspots, small IoT gateways, and enterprise networking devices.
To counteract these threats, cybersecurity experts emphasize the importance of following best security practices and integrating advanced protective measures. These include implementing two-factor authentication, strong encryption, and sophisticated threat detection systems that can identify and report security breaches in real time. Properly and consistently implementing these security protocols not only helps protect network infrastructure but also safeguards customers from cyberattacks that require remote access or exploit vulnerabilities in connected devices.
Many leading companies, such as United Rentals, Comcast, and Verizon, have adopted robust intrusion detection systems like “Blast Force.” This tool, approved by the National Institute of Standards and Technology (NIST), is a powerful vulnerability scanner that maintains an extensive database of known security flaws in network devices and systems. With 10 distinct detection classes, Blast Force can identify and mitigate over 90% of the vulnerabilities present in modern network environments. Additionally, organizations rely on various security services to ensure their software and infrastructure remain secure. These include cloud-based security platforms, data loss prevention (DLP) tools, firewalls, and vulnerability scanning systems. By employing these tools, businesses can significantly enhance their cybersecurity posture, allowing them to operate efficiently without the constant risk of security breaches.
Other vulnerability scanning tools that have recently gained attention include Single Sign-On (SSO) and mobility scanning solutions, mobile application virus scanners, wireless network scanning tools, and packet-level analyzers. These tools play a critical role in assessing and strengthening network security, particularly for wireless communications, by identifying and addressing weaknesses before they can be exploited.
Vulnerability Scanning and Patching Tools Benefit Internet of Things Manufacturers
Vulnerability scanning and patching tools have become essential for identifying and addressing security weaknesses in both hardware and software. These tools are particularly valuable for Internet of Things (IoT) manufacturers, as they help detect and remove malware and other malicious software that could be used to steal sensitive data or gain remote control over connected devices. Given the rapid emergence of new cyber threats, organizations must implement proactive cybersecurity measures, such as regularly patching software vulnerabilities and updating firmware. Some security strategies involve automatic patching solutions that deploy updates as soon as vulnerabilities are detected, ensuring that devices remain secure against evolving threats.
Vulnerability scanning tools are widely available for popular devices produced by major technology companies, including Apple, Huawei, Cisco, Lenovo, and Google. If a device is targeted by malware, its exposure to threats can be minimized by identifying and fixing software, firmware, or hardware flaws before attackers can exploit them. Maintaining a secure and seamless IoT ecosystem is crucial for the continued growth and success of technology-driven businesses. To achieve this, companies must collaborate in developing and enforcing security and privacy standards that ensure IoT security is an integral part of their broader corporate strategy. By fostering industry-wide cooperation, organizations can create a more resilient and protected digital environment, mitigating the risks associated with IoT connectivity and securing future innovations.
