| Linux to the rescue: A review of three system rescue CDs | ||
|
30th, June, 2005
We've all had this nightmare. You turn on your functioning Windows/Linux PC, and all you get is a blank screen, or a message telling you that certain files are missing, or the kernel has panicked for some obscure reason. Nothing works, and you need the data on your machine. Yes, now's the time to whip out that trusty backup disk, and heave a sigh of relief that all the important stuff is backed up, right? Well, think again. |

| What is the Best Firewall for Servers? | ||
|
28th, June, 2005
I maintain a bunch of servers at our labs in the university. Of late, the number of attacks on the computers has been more noticeable. The university provides firewall software (Kerio) but that doesn't work with Win 2003. And so we keep getting hit by zombie machines taken over in the Education Department or from Liberal Arts. So what does the Slashdot crowd use when they need to secure their Linux and Windows servers? Does it cost less than US $100? |

| Xen Developers Focus on Security | ||
|
28th, June, 2005
With the next major release of the Xen Virtual Machine Monitor expected this August, the project's developers have turned their attention to a new issue: security. Over the last few months, a group of the project's open source developers have begun work on a "security enhanced" version of Xen called XenSE that is similar in concept to the Security Enhanced Linux project backed by the U.S. National Security Agency (NSA). |

| Browser Identification For Web Applications | ||
|
27th, June, 2005
Browser identification is not a new concept. With the focus having shifted to desktops from networks and servers, a topic such as remote browser identification needs to be revisited. |

| The Going Gets Hot | ||
|
28th, June, 2005
As if angry customers, declining consumer confidence, and the threat of fines weren't enough, business executives have something new to mull on the troubling issue of lost or stolen customer data. Two U.S. senators are floating the prospect of jail time for business leaders who knowingly conceal such breaches. If top managers can't secure data in a well-guarded environment, well, perhaps they'll find themselves in one. |

| Virtual Private Servers Virtualize the OS | ||
|
29th, June, 2005
In today's never-ending crusade to reduce IT costs, various techniques are used to squeeze every drop of computing power out of servers. One popular technique is consolidation. Through consolidation, under used servers are subdivided into smaller, more usable pieces. And with these pieces, you generally achieve greater server performance overall. Often, it completely eliminates the need for some of the physical servers. |

| Open-source projects get free checkup by automated tools | ||
|
29th, June, 2005
More open-source software projects are gaining the benefits of the latest code-checking software, as the programs' makers look to prove their worth. On Tuesday, code-analysis software maker Coverity announced that its automated bug finding tool had analyzed the community-built operating system FreeBSD and flagged 306 potential software flaws, or about one issue for every 4,000 lines of code. The tool, which identifies certain types of programming errors, has previously been used to find flaws in other open-source software, including the Linux kernel and the MySQL database. |
