Beware of sites that say you need the latest Flash player
One of the most common scams criminals use is to tell you to “click here to download the latest flash player” using the real flash logo and everything. Only get the flash player and updates from www.adobe.com – never a link on some other web site. Stay safe!

You may never know your computer is infected
Think about it. If a cyber criminal is monitoring your computer to steal your passwords, they do NOT want you to know.

How are the hackers getting past your firewall?
I get calls from IT Professionals asking what to do when a cybercriminal is trying to log in through the network remotely with a brute force “password guessing” attack. The IT professionals often state they are surprised an outsider could do this “since the firewall was up and running.”
I’m used to executives wanting a single “silver bullet” to take care of security, and am educating them and their IT professionals alike that no single IT security device or strategy can be viewed as complete on its own.
For example, these two statements are wrong: “I know we are safe because our firewall is up and running.” “I am safe traveling on the road because I always connect to my office through a VPN.” Firewalls and VPN’s are wonderful IT security tools – mandatory security tools if you ask me – and they are not enough. Today’s cyber security situation is so dire that you need many different layers of protection in place. There is NO SUCH THING as an IT security “silver bullet.”
Does it help not to open e-mail from strangers?
An executive recently wrote me, “I got a virus that infected our network because I opened an e-mail message from someone I didn’t recognize – I’ll never do that again!”
While that strategy may help some, it is far from being a reliable way to protect your network. First of all, without performing some technical detective work, it is hard for a non-IT professional to tell who the e-mail came from anyway. You may get an e-mail from a cybercriminal who uses “spoofing” to make the e-mail message appear that it is coming from your best friend, bank, the FTC, or anyone else.
Better protection comes from scanning tools running at one or more locations including your e-mail server, your firewall, your spam filter, and the anti-virus client on your local machine.
Training users “not to open e-mail from strangers” is a moot point if your user is supposed to open e-mail messages from prospects interested in your company’s products and/or services. There is some training that matters though…

Should you be worried about the virus attack on April 1?
Yes, there is a lot of concern over a “really bad virus” attacking on April 1. Should you be concerned? In fact, many computers are already infected.
The virus goes by the name of Conficker and it is also known as Downadup (and also Downup and Kido). My advice remains the same as always: be concerned about a really bad virus every single day of your life. If you are following IT security best practices, then there is nothing more to do in preparation for April 1.
Still, I was amazed during the Y2K bug nine years ago how many executives decided, “ok, let’s go ahead and take appropriate IT steps since there is a deadline.” If your organization has been postponing some of the simple IT security basics, maybe Conficker’s “bright side” is that you’ll do what needs to be done.
Details of some of the steps to take include:

Can you not decide what sites to block?
Many organizations fail to implement web-blocking technologies because of the arguments that erupt around what is and what is not inappropriate content to block from employees on the job. Keep in mind that most web blocking tools block by category such as, “gambling sites” and “news sites.”
This frustration and confusion causes the organization to not filter any sites at all. Here is a simple way to move forward on your protection.
