What are the best ways to remediate VPN audit vulnerabilities?

2 Choose strong encryption and protocols

Another way to remediate VPN audit vulnerabilities is to choose strong encryption and protocols for your VPN connection. Encryption is the process of transforming data into unreadable code that can only be decrypted by authorized parties. Protocols are the rules and methods that govern how data is transmitted and received over the VPN connection. Strong encryption and protocols can protect your VPN data from interception, modification, or theft by hackers, spies, or other malicious actors. You should avoid using outdated or weak encryption and protocols, such as PPTP, L2TP, or DES, and opt for more secure ones, such as OpenVPN, IKEv2, or AES.

3 Configure your VPN settings properly

Remediating VPN audit vulnerabilities can be achieved by configuring your VPN settings properly. These settings can influence the speed, reliability, privacy, and security of your connection. Authentication is a key component, and you should use strong methods such as certificates, tokens, or multi-factor authentication. Firewall should be enabled and configured to allow only the necessary ports and protocols for your VPN connection while denying any other traffic that may pose a threat. Additionally, a secure and reliable DNS service should be used for your VPN connection. This could be your VPN provider's own DNS or a third-party DNS that supports encryption and privacy, such as Cloudflare or Google. You must also be aware of DNS leaks which occur when your DNS requests are exposed to your ISP or other parties outside your VPN network.

4 Monitor and test your VPN performance

Monitoring and testing your VPN performance regularly is a fourth way to remediate VPN audit vulnerabilities. This can help detect and resolve any issues that may affect your VPN security and functionality, such as slow speed, connection drops, or IP leaks. To monitor and test your VPN performance, you can use various tools and methods, such as a speed test, ping test, and leak test. Speed tests measure the download and upload speed of your VPN connection, while ping tests measure the latency or delay of your VPN connection. Leak tests check if your VPN connection is leaking any information that can reveal your identity or location. You can use online tools to perform these tests from different locations, servers, browsers, and devices to find the best ones for your VPN connection. Reporting and documenting the incident will help you inform and reassure the stakeholders, as well as provide valuable insights for improving your cloud security posture.

5 Educate and train your VPN users

Educating and training your VPN users is a fifth way to remediate VPN audit vulnerabilities. VPN users are people who access the VPN network, such as employees, clients, or partners. They can be a source of VPN vulnerabilities if they are unaware or careless about the VPN security policies and best practices. It is important to educate and train them on how to choose and use strong passwords and authentication methods, update and maintain their software, operating system, and applications regularly, avoid using public or unsecured Wi-Fi networks or devices when connecting to the VPN network, avoid downloading or opening suspicious or malicious files or links from the VPN network or the internet, and report any suspicious or unusual activity to the VPN administrator or security team.

6 Review and improve your VPN policy

A sixth way to remediate VPN audit vulnerabilities is to review and improve your VPN policy periodically. This policy should define the purpose, scope, and operation of the VPN service, as well as specify the roles and responsibilities of its stakeholders. It should also establish and enforce security standards and best practices, and monitor and evaluate the VPN performance and compliance. When reviewing your VPN policy, make sure to align it with your business goals and needs, as well as the legal and regulatory requirements of your industry and location. Additionally, update it with the latest VPN technology and trends, as well as emerging threats and challenges. Furthermore, communicate it clearly to all stakeholders while soliciting their feedback and suggestions for improvement. Finally, audit and assess it regularly to measure its effectiveness and efficiency, while identifying any VPN gaps or issues that need to be remediated.
