Security

With security being such an important part of every task a sysadmin undertakes, and with the stakes so high, we are starting a new series on the GFI Blog that deals with Security 101. The last week of every month, we will cover something along the lines of a “Security 101” topic to help those who need security, but don’t have the background, to improve their skills.

We’ve collected a list of the skills that are most important to sysadmins, no matter what their specific focus is – check it out!

Two things that really upset people when they try to connect to a wireless service is that a) the connection is not free and b) that it doesn’t work properly.

Europol issues warning regarding public wi-fi networks   Industry experts have been proclaiming for a while now that we’re headed toward a world without wires. Some pundits have predicted that new fast wireless technologies, capable of gigabit speeds, will usher in the death of Ethernet. The majority of home networks are wi-fi based. Companies connect […]

There’s been a great deal of discussion about the “digital divide” in regard to people who have access to affordable broadband and those who don’t. But there’s another, more fundamental divide – related but different – that has been developing over the years since computing went mainstream: the psychosocial division between those who understand how […]

We reported here previously on the major security flaw in both Apple’s desktop and mobile operating systems that allowed attackers to intercept communications with SSL-protected web sites. The vulnerability became widely known last week, although it has apparently existed for months.  Apple released a patch to fix the problem in iOS on February 21, but […]

The “Miracle on Ice” at the 1980 Winter Olympics is widely considered the greatest U.S. sports moment of all-time – and with excellent reason.
