This week's Word of the Week is Phishing. What exactly does it involve and how can you prevent unsuspecting people from becoming victims of it?

Spear Phishing: Is Your Boss a Whale?
Spear and whale phishing 1have been around for a while now, but recent social engineering efforts are focusing more on company executives. An example is this type of email: it certainly looks legit at first glance; even the phone number and address – right down to the floor number – are correct. But take a closer look at the URL used in the links: the real site has no relation to puzzlejs-mailing.com. (Jul 29, 2010)
Who is Responsible for Internet Security: A Response
Basically you have the Australian courts who want to place the onus on the shoulders of end-users. Others want to put the responsibility on Operating System or Application vendors due to their security holes.

My spam is different from your spam!
The type of spam you receive depends on many things, including your behavior on the net, how you use your email address, your position in a company and much more.

Well, at least that's what our Security Operations team tells me. (Jul 22, 2010)
Surfing on Web 2.0: Where Innovation Meets Cybercrime
Yesterday, I logged into Facebook. I usually never use my account there (I am not a Facebook fan), but once in a while I’ll spend some time on it. For the first time, after entering my credentials, a “security” page appeared stating that unusual activities have been witnessed on my account. I then had to answer some questions, choose the names of some tagged friends, and reset my password. I have no idea what happened or how my account got compromised. (Jul 20, 2010)

Organized Cybercrime

Glenny, a former BBC world correspondent, presents a terrifying yet eye opening look at how organized crime has progressed with Globalization over the last few decades. Glenny covers all the major illicit activities from global drug trafficking networks, to prostitution and human trafficking.

Who’s responsible for Internet Security?
A couple of stories in the news today caught my attention because they have very opposite perspectives on tackling cybercrime and Internet security. First, the Australian government is thinking of making home computer users responsible for security1. They’re contemplating legislation to force users to install anti-virus programs and firewalls on their home computers before being allowed to connect to the Internet. (Jun 23, 2010)
Why Your Business Needs Policy Management
Instead of being reactive to scandals and managing them after the fact, organizations should take a proactive role and protect data leakage before it happens, to prevent the loss of secrets that are revenue generating. However, most companies are still under-protected and focus their security budgets on compliance and protection of custodial data (customer personal information) rather than internal information such as corporate/product strategy, or financial reports which directly affect the bottom line.

Angelina Jolie wants to be my friend: The pitfalls of social media
I guess writing this blog brings some perks after all.

Interesting question from a customer: “Why should we block .EXEs?”
The majority of phishing attempts with drive-by-downloads try to entice you to download EXE files and run them locally. EXE files should always be blocked. You can open certain files on a case-by-case basis and in a very controlled fashion, but that’s the extent of it. (May 26, 2010)
