What does Email Security mean to you?
When it comes to securing your organization’s email, you want to protect all aspects of email flow: inbound, local-to-local, and outbound. (Sep 01, 2010)
“You can’t fix stupid”
HostExploit people named Demand Media the worst ISP in the world because of the number of botnet control centers they host and the sheer volume of junk that spews from its network. They reportedly host an estimated 7,400 infected websites. (Aug 19, 2010)
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’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)
Angelina Jolie wants to be my friend: The pitfalls of social media
I guess writing this blog brings some perks after all. I’ve been nominated to ‘represent [my] professional community’ for every possible Who’s Who list, Facebook invitations are coming in fast and furious, I’m getting offered all kinds of free product subscriptions, and, judging from my message content, I think my 15 minutes of fame have finally arrived!

Here come the spam police
The German courts may have just opened the floodgates. Their top criminal court ruled this week that home wireless users can be held responsible for not password-protecting their wireless connections. If the unprotected connection is used for illegal file downloads, the owner can be fined up to 100 Euros (currently $126). (May 17, 2010)
Your mail server might not be the cause of delivery problems
Most support people have seen every mail server configuration possible, and others that would have been considered impossible. No matter whether the operating budget is very tight, mega-sized or somewhere in between, people often try to throw everything onto a single server, including the kitchen sink. Well, that kitchen sink is often the cause of email blockage, rather than the actual mail server program. Even a honking new machine with mega-sized specs can have performance problems if it becomes bloated with unnecessary and/or resource hogging apps. (May 03, 2010)
Why can’t you stop this spam?
Maybe you’ve seen more spam hitting your Inbox over the past couple of months and wondering, “Why am I paying for filtering? This stuff is obviously spam – why can’t you guys stop it?” The main challenges of being in the spam filtering business are dealing with clients’ expectations on the one hand, and the sheer size of the spam/malware machine on the other.

Policy Compliance: Keep it Simple, Stupid!
Are you getting pressured to provide some sort of regulatory compliance rules to your business that will affect your network configuration, your email flow and your end users? Do you have to deal with SOX or HIPAA or GLBA, or ‘Oh Lord, not another Acronym’ regulation (we’ll call it the OLNAA) whose apparent sole purpose is to complicate your life? (Mar 24, 2010)
Spamhaus releases a new spam-fighting tool
Spamhaus publicly released its new Domain Block List (DBL)1earlier this week, after beta testing it for much of last year. They claim they have had “exceptionally positive” results from the testing, and the premise is really quite interesting. (Mar 03, 2010)
Who’s minding the store at WHOIS?
WHOIS (for those unfamiliar with it) is a system that provides free public access to domain name registration. Every domain name has to be registered with the following information: the registrant’s name, an administrative contact, a technical contact, and the name servers associated with each domain name. It’s all about traceability. (Feb 17, 2010)
How would you punish a spammer?
“Last time out I suggested sentencing spammers to some quality time in a maximum security cell with an ex-biker named "Tiny." But I think that's too good for these people. They should be strung up by their thumbs and forced to watch ShamWow infomercials and Rick Astley videos until their ears bleed.” Robert Cringely, InfoWorld 1 (Feb 03, 2010)

You only have one reputation – don’t lose it
Having a bad reputation might have seemed cool when you were a teenager, but if your email server has been given a bad rap, it’s definitely UNcool – especially if your business depends on delivering email. Trying to get your reputation back can be time consuming and costly, so the best approach is to do your utmost not to lose it in the first place. (Dec 02, 2009)
What, me worry?
Incidents of cybercrime via malware and exploits are on the rise, but if this recent poll is to be believed, people are still too blasé about their Internet security. The Unisys Security Index: Global Summary report 1 revealed the following: “Concerns over security in everything from online shopping and banking to safety from computer viruses, as well as national security along with personal and financial security, were significantly down over what was recorded half a year ago for populations in the United States, the United Kingdom, Germany, Belgium, Brazil, Netherlands, Spain, Australia and New Zealand.

The Future Of Email Security: Where Do We Go From Here?
There’s no denying that anti-spam filters are imperative in the fight against junk mail and malware, but no single solution is fool-proof. Employing anti-spam and virus filters, stronger passwords, encryption, and so on, are not enough to win the battle against the ever-increasingly sophisticated attackers. (Nov 04, 2009)
Drive by Downloads
This is a term I’m seeing more and more frequently in security-related web posts and, frankly, I thought it was fairly new. After doing some research, however, I found an article entitled, Anatomy of a “Drive-by-Download,” that was written in 2004 (!) by Eric L. Howes. Where have I been all this time? (Oct 21, 2009)

“ElephantGate” and other stories
Ah the “Dog Days” of August! Give me a hot, sunny day, a comfortable lawn chair and a really good spy novel, and I’ll get lost for hours. But who needs books these days? A recent article about corporate espionage reveals a wealth of true-life - and often truly bizarre – tales. Move over James Bond, the company janitor has cool gadgets too! (Aug 26, 2009)
