TLS/SSL vs IPsec: The Trade-offs

Blog
A look into the trade-offs between TLS/SSL and IPsec in terms of their requirements, authentication methods, overall performance (speed and strength), service transparency, operational complexity, and other characteristics.  Authentication Methods: TLS/SSL begins with a Secure Sockets Layer (SSL) handshake process to agree on which protocol to use. Once a secure connection is created the next step is to exchange certificates and keys as needed.  IPsec is a network-level protocol that requires setup before on both servers and the client.  Overall Performance (speed & strength): As far as performance, TLS/SSL is faster, however IPsec setup in Transport Mode is getting close in speed. When looking at the strength of security, IPsec setup in Tunnel mode will be mo...

Splitting the app across multiple files also helps with debugging and being able to reuse code for another project. Separating the files for a Shiny Application also helps with version control For this post, the actual code and what it's doing will not be covered. The code is more of a placeholder and this is creating a project framework to start Shiny applications. Creating a new project The best practice is to create a new project for each application.

Windows Patch Tuesday gets Exciting On the last day of support for Windows 7 news breaks of a severe Windows 10 bug. The bug was so severe the NSA told Microsoft once it was found, or did they? https://techcrunch.com/2020/01/14/microsoft-critical-certificates-bug/ This bug was related to digital signatures, which is used as a defense against users downloading malware disguised as a typical program. However, due to the bug an attacker could include a digital signature from a trusted provider on any files they wanted. Once an unsuspecting user downloads those files their system could be compromised because of the digital signature Windows 10 would believe its safe. Below is a tweet from the NSA "Strongly" encouraging users to update their Windows 10 OS https://twitter.com/...
