Benjamin Franklin once said, “If you fail to plan, you plan to fail.” This quote summarizes the importance of online encryption policy and hands-on implementation within an organization.
Though you may have the best IT department in the world and advanced computing resources, if there are no written methodical steps […]
Also known as the term additive manufacturing (AM), 3D printing is a process for making a three-dimensional object of almost any shape starting from a 3D model or other electronic data source.
Through additive processes, a 3D printer adds successive layers of material to compose the final shape under the […]
In the first part of our article we solved the first three challenges, so in this article we will continue with rest of the challenges.
CHALLENGE #4: OUCH!
TRACE FILE: challengeattack.pcapng
BACKGROUND: These capture files were taken from a network that was experiencing a “zero-day” attack and was completely overwhelmed. It is […]
In this article we will learn about a very famous security product of Microsoft known as Microsoft Direct Access. It is a product built over an old security concept of Virtual Private Network (VPN), but with completely different technology. So let’s dig deeper into this.
What is DirectAccess?

In this article, we are going to see what are federation, single sign-on, and three federated identity standards, namely Security Assertion and Markup Language (SAML), OpenID and OAuth. We will also see the shortcomings observed in each standard.
The three federated identity standards that we will talk in this article […]
Steganography is often mistaken with cryptography, but they are very different in their operations. The major similarity between them is they were coined from Greek words.
steganos – covered
cryptos – secret
graphos – writing
That gives us hidden writing for steganography and secret writing for cryptography. Fill out the form below to […]
