Improve Tumblr Security by Enabling Two-Factor Authentication

Wednesday, March 26th, 2014

Two factor authentication does provide improved security over a standard password, but I’m not sure if I’m all that crazy about giving my phone number out to companies that might end up selling that information later.

Tumblr announced today that Two-Factor Authentication is now available for all users of the site. Two-Factor Authentication adds a second layer to the log in process on websites.

That code is generated in real-time, usually through smartphone apps, SMS or hardware devices that can generate codes on demand.

This sounds like a helpful move; improved security and authentication are always a good thing.

And while that may not be an issue for some activities online, you better be sure when you sign into accounts or handle financial transactions on sites such as PayPal or your bank’s online presence.

Given the powerful remote access capabilities that a terminal switch ( provides in an out of band management application, it’s absolutely vital to ensure that a terminal switch includes adequate security features to protect critical console port command functions from unauthorized access. Almost all terminal switch units include basic security features such as password protection, but in many terminal switch applications, simple password security isn’t enough; that’s why it’s important to select a terminal server product that supports additional, advanced security functions functions such as authentication and encryption such as HTTPS and the ability to create SSL security certificates.


Add SSL to CentOS Web Server

Monday, December 6th, 2010

Here’s a handy trick for Linux users …

CentOS might well be one of the finest Linux distributions for a server environment. It is basically a mimic of Red Hat Enterprise Linux without the proprietary software and the price attached to it.
