Your company’s security is ensured by virtual private networks. To protect your connections, they use encryption. When accessing an unprotected internet infrastructure, a VPN is required.
It gives you anonymity and security, keeping hackers at bay. VPNs, however, are not impenetrable. They, like passwords, can always be compromised.
Here are a few tips for increasing the security of your site-to-site VPN.
Use 2FA/MFA
VPN authentication cookies to circumvent authentication, and client certificates to bypass authentication. In such circumstances, enforcing 2FA/MFA is your best option. It may be your final line of defense. A strong password policy is usually a smart idea. This could save you time and stress.
Avoid IPv6 Leaks
IPv6 is a subset of the Internet Protocol. It allows you to access more addresses than IPv4. The issue with IPv6 is that it operates outside of VPN territory. This implies that hackers can find out who you are
Fortunately, you may always do a test to ensure your safety. Alternatively, you can disable IPv6 manually.
Instead of SSL, use IPSec for your VPN.
IPsec VPN may be a better choice than SSL VPN. Create a method for balancing the security concerns of both network connection encryptions. The key distinction is in the network layers where authentication and encryption take place. IPsec operates on the network layer. It can be used to encrypt data delivered across any IP-identified system.
SSL operates on the transport layer. It encrypts data exchanged between any two processes on network-connected hosts indicated by port numbers.
Furthermore, IPsec does not expressly describe connection encryption. SSL VPNs, on the other hand, will encrypt network communication by default. IPSec VPN is important to most threat models, despite the fact that they are both safe.
Make use of the OpenVPN Protocol.
VPNs can support a variety of protocols to give varying levels of protection. The following are the most prevalent protocols:
- PPTP
This therapy is less effective than the others. It has a 128-bit encryption key. Hackers have the ability to intercept the connection and authentication procedure. They have the ability to decode your data and jeopardize your security.
Despite its lack of encryption, PPTP has one major advantage: it is one of the quickest protocols.
- L2TP
This protocol provides greater security than PPTP. It is, however, slower and has higher operational costs.
- OpenVPN
This protocol provides you with the highest levels of security and privacy. It is quick, and you can immediately restore any lost connections. When you wish to provide the highest levels of security, consider adopting VPN solutions that support OpenVPN.
Avoid DNS Leaks
DNS leaks are security weaknesses that allow ISP DNS servers to see DNS requests. They prevent your VPN from concealing the requests. In such cases, you should contact your vendor to see if they have DNS leak prevention. If they don’t, it’s time to find another option.
Make use of Network Lock.
When your Wi-Fi network is disrupted, a network lock prevents your computer from accessing the internet. As a result, your data remains secure even as your VPN reconfigures.
Make use of a kill switch.
If your VPN connection fails, you may be forced to use an unprotected connection provided by your ISP. This is prevented by a kill switch. When a connection is lost, it prevents apps from shutting down and restricts access to websites.
Remote Wireless Network Security
VPNs are excellent for protecting insecure wireless routers. However, the vulnerabilities in your wireless routers may cause issues. They have the potential to damage the efficiency of your VPN. Request assistance from your IT department in securing the networks.
Implementing the aforementioned recommendations will increase your VPN security. It is not, however, impenetrable. To increase the efficiency of your safety measures, you should combine them. The suggestions above will dramatically improve your data security. They reduce the likelihood and severity of breaches.
If you are dissatisfied with your VPN, the market is brimming with alternatives that may meet your security requirements. Investigate them and select the best one for your requirements. Don’t assume that what works for someone else will work for you.
