Virtual Private Networks (VPNs) are widely adopted solutions that enable secure remote access to internal networks over the public Internet, offering benefits such as data encryption and masking of IP addresses. However, despite their advantages, VPNs can also become vectors for additional security threats if not implemented and managed properly. One significant scenario where VPNs might introduce risks is when mobile devices are involved. As highlighted by Tmi D., many mobile VPN applications do not appropriately encrypt traffic or are vulnerable to misconfigurations, thereby creating pathways for attackers to exploit. For example, the analysis revealing that 84% of VPN apps on Google Play fail to encrypt traffic adequately highlights the vulnerabilities associated with poorly secured mobile VPNs (Tmi D., n.d.). Such vulnerabilities can lead to data interception, man-in-the-middle attacks, and malware infiltration if attackers manage to exploit these flaws. These threats are compounded when users connect via unsecured or untrusted networks, such as public Wi-Fi hotspots, where malicious actors can intercept unencrypted or misconfigured VPN sessions, undermining the core security tenets of confidentiality and integrity (Kim & Solomon, 2016).

Furthermore, the use of VPNs introduces potential threats from side-channel attacks, as discussed by Caruso (2021). Although modern encryption standards like AES are robust, they are not invulnerable. Side-channel attacks exploit physical characteristics such as power consumption, electromagnetic emissions, and timing information to infer cryptographic keys. In remote or poorly shielded environments, these physical vulnerabilities can be exploited by sophisticated adversaries, compromising the security of even the strongest encryption algorithms. To mitigate this, organizations should implement security measures such as shielding cables, using power conditioners, and deploying uninterruptible power supplies (UPS) to minimize physical side-channel vulnerabilities (Caruso, 2021). Additionally, new threats such as brute force attacks become relevant if VPN configurations use short or weak encryption keys, exposing the network to compromise. Hence, enforcing strong key management policies, using longer key lengths, and continually updating encryption protocols are essential steps for security (NIST, 2020).

Another concern arises when VPNs are poorly configured, such as using outdated protocols or weak authentication mechanisms. This can allow attackers to exploit known vulnerabilities, leading to unauthorized access and data breaches. Ensuring the deployment of current protocols like IKEv2/IPSec or WireGuard, alongside robust multi-factor authentication, significantly reduces these risks (Raghunathan et al., 2022). Moreover, continuous monitoring, regular security audits, and deploying intrusion detection systems help identify suspicious activities early, preventing potential attacks facilitated through VPN channels. Policies should also emphasize secure endpoint management, ensuring devices connecting via VPN are updated, encrypted, and free of malware, thereby reducing insider threats (Alotaibi & Kent, 2021).

In conclusion, while VPNs are vital tools for securing remote communications, their deployment must be carefully managed to avoid adding vulnerabilities. Proper encryption practices, physical protection against side-channel attacks, strict configuration policies, and continuous security monitoring are essential. By adopting these protective measures, organizations can effectively mitigate the risks associated with VPN usage, ensuring secure and resilient internal network access.
