VPNs are critical pieces of the enterprise cybersecurity infrastructure. When it comes to protecting data in motion, there's really no good substitute. And that's why it can be so devastating to learn that this mandatory tool can carry vulnerabilities.
Before going any further, it's important to note that nothing here is intended to suggest that your organization ditch its VPNs. Networking with VPNs is vastly more secure than networking without them. With that said, there's no part of the enterprise IT infrastructure that qualifies as "set it and forget it," and VPNs are not exceptions to this rule.
The dangers represented in this article fall into two broad categories; first are the vulnerabilities that are "designed in," featuring problems with the logic, installation, or basic features of the VPN's client or server.
Vulnerabilities in the second group are "classic" vulnerabilities — inadvertent errors in the code running on one side or other of the VPN, an issue with how a protocol is implemented, or something similar.
A number of the vulnerabilities listed in this article have been patched in recent versions of the software, illustrating once again the importance of keeping software updated and fully patched. More than that, the vulnerabilities listed here are a reminder that cybersecurity means looking at every piece of the IT infrastructure, whether it's provided by the business or brought in by the employee. That goes for services as much as for products, and for security services as much as personal productivity applications.

In most cases I tend to think that the problem is that loose nut behind the keyboard, But each of these are problems that land right in the lap of IT. But is there a site that will give you the straight poop on the different VPN Providers? Until you develop a relationship with your provider the sales weasels will be quick to tell you "Sure we do. Everything is fine.".
Everything You Need to Know About DNS AttacksIt's important to understand DNS, potential attacks against it, and the tools and techniques required to defend DNS infrastructure. This report answers all the questions you were afraid to ask.
Domain Name Service (DNS) is a critical part of any organization's digital infrastructure, but it's also one of the least understood. DNS is designed to be invisible to business professionals, IT stakeholders, and many security professionals, but DNS's threat surface is large and widely targeted.
Attackers are causing a great deal of damage with an array of attacks such as denial of service, DNS cache poisoning, DNS hijackin, DNS tunneling, and DNS dangling. They are using DNS infrastructure to take control of inbound and outbound communications and preventing users from accessing the applications they are looking for. To stop attacks on DNS, security teams need to shore up the organization's security hygiene around DNS infrastructure, implement controls such as DNSSEC, and monitor DNS traffic
How Enterprises are Developing Secure Applications
Recent breaches of third-party apps are driving many organizations to think harder about the security of their off-the-shelf software as they continue to move left in secure software development practices.
