Network Security Protocols: Background Part I

By Jojo Maalouf

As an IT security professional, one of the areas where I gained a significant amount of knowledge and experience in is network security. Working for a telecommunications company, it’s pretty much a given that if you are working in security, you are dealing with network security protocols such as IPsec, SSL/TLS and SSH. I started off primarily working with IPsec and eventually was exposed to TLS and finally, SSH. One of the real issues that I first encountered was differentiating between these network security protocols. It took me time to be able to understand and explain the following:
“What is the difference between these network security protocols?”
“Which one shall I use?”

To Click or Not To Click

By Kim Edwards

From my previous post – Is your computer secure– I indicated that novice users should never click on links. In this post, I will help you identify bad links and give you tips on when to click on a link.

When receiving a curious link, most users enter a split personality mode like Smeagol in Lord of the Rings. Your alter ego says click on it, while your heart says don’t. Unfortunately, sometimes the alter ego prevails, we click and we get infected or Phished. Let’s decompose a link so that you can make educated decisions on whether to click or not.

Is your computer secure?

By Kim Edwards

Security is not an easy thing for the average consumer. The methods and procedures to ensure that you are not vulnerable to attacks are typically difficult and prone to configuration errors. With so many solutions out there, where does a consumer start?

Since Windows dominates the consumer market, let’s focus on securing this beast. Let’s use the analogy of physically securing one’s house. If I lock the door with my super expensive medico lock, but I leave my basement window open, am I secure? So I then lock all my windows, great I am now secure … Wrong!! The thief kicks on my door which has the expensive lock but I forgot to reinforce my door frame and within 5 big kicks, the thief is in. I reinforce my door to the point that the thief will need to drive a car through it. Haha, I showed that thief that he cannot mess with me … Wrong again!! The thief breaks my basement window and enters my house again. Now I need lock bars across all Windows and make it look like Alcatraz except people are trying to get in instead of out. I hope that you are starting to see my point.
