Linux, like Microsoft Windows, is simply a computer operating system but Linux in itself is not a magic wand that can be waved and make all sorts of computing problems disappear. While Windows has its own set of problems, so too does Linux. There is no such thing as a perfect or completely secure computer operating system. Whether the machine will be a desktop computer or a server; purpose is a key to understanding how to initially install and configure your Linux PC.

Spam spits out Linux in high volume attack

Struggling to cope with increasing volumes of spam, Deakin University was forced to redeploy its Linux e-mail servers and implement an alternative system for e-mail security. Craig Warren, Deakin's operational service provision manager, said the Linux servers running antivirus and spam filtering software were effective for about three years, but "the spammers were steadily beating us".

Gartner: 2005 hurricanes prompt more companies to store data off-site

The number of companies making copies of data to protect it has dramatically risen in the wake of hurricanes Katrina and Wilma this year, but most of those companies are keeping that duplicate data locally where it's still vulnerable to disasters, according to a survey released yesterday by Gartner Inc. The September survey of 104 North American IT managers showed that 45% of respondents back up or replicate data to another disk, up from just 6% who did so in 2004. But 70% of the respondents who make backups do so to a local device.

Simplifying backups

Most computer users don't make use of a system backup tool until after they suffer the misfortunes of a hard drive crash without one. But even then, many find backup software too complicated to configure, and there seems to be little in between creating CD or DVD archives by hand and overpowered network backup systems designed for the enterprise. The Simple Backup Suite (sbackup) is a tool for configuring regular backups of system data and simplifying full and partial recoveries.

Applying Security to Web Servers

Web servers are among the most obvious targets for black hats. Whether used for basic e-commerce or more advanced Web services, they give attackers an always-on interface to an IT system and often a shortcut to the parts that handle financial transactions. Even better for the attacker, they increasingly run custom applications developed in-house. These are more likely than the basic Web server software to contain security vulnerabilities, as they haven't been subjected to the rigorous quality control procedures of the open-source community or a commercial vendor.

Hey Linux Users: No Software Is Impenetrable

The bug that besets a Windows network today is very likely to infect a Linux or Unix network connected to it. Similarly, companies that fail to secure their Linux networks may find rogue code spreading and infecting interconnected Windows networks. Security is one of the foremost and fundamental components of the network infrastructure Latest News about network infrastructure and one that will negatively or positively impact the daily operations of any business. No software code or hardware device, be it proprietary oropen source Latest News about open source, is immune to hacks.

Secure remote file management with sshfs

It's a dangerous Internet out there, kids. If you are going to work on remotely connected machines, do it safely. Simple file transfers and interactive sessions have scp and ssh respectively; in fact there is hardly a commercial Web hosting provider left that doesn't support them. For more complicated scenarios we have VPN tools. But what if you need to work with files on a remote server, but find scp tedious in repetition and FreeS/WAN too cumbersome? You might find just what you're looking for in sshfs -- a tool for mounting a remote filesystem transparently and securely as if it were just another directory on your local machine.

Steps for preserving the integrity of log data

In the past few years, companies have spent billions of dollars to update their IT infrastructures to meet requirements from various European and US government regulations. One of the more noticeable and most important recommendations of these regulations is record-keeping. For example, Sarbanes-Oxley recommends that all companies "maintain financial records for seven years." In order to ensure the accuracy of corporate financial and business information, this recommendation also pertains to records that are used to "audit unauthorised access, misuse and fraud." Other regulations such as HIPAA also recommend keeping records for up to six years.

Easy and efficient patching all comes down to having the right management software

If cars were sold in the same way as software, you would have to hook your Mondeo to the internet and download the latest code update before you left the garage. Managing software patches across an organisation can be one of the biggest headaches for IT departments, but luckily there are products to help.

Better Backup Strategies

If your organization depends on tape backup, it's time to think about tapering off. Here are five ways to improve data protection and backup with less tape. IT architects are talking a lot these days about getting rid of tape, and for a multitude of reasons--it's too slow and hard to use, hard disks have gotten cheaper, certain databases and applications require faster recoveries, and so on. According to consulting firm TheInfoPro, 90 percent of companies plan to move from tape to Serial Advanced Technology Attachment (SATA) disk drives as part of their backup/recovery and data lifecycle management plans by 2006

Linux: Secure as You Want It to Be

Opinion: Yes, Linux will be attacked more often in the days ahead, but far fewer attacks will get through than do on Windows. My colleague Larry Seltzer thinks that we may be on the verge of an age of Linux worms that might rival the endless trouble that Windows users find themselves in.

Linux in Action: Understanding Federated Identity Management Business Drivers

What's Federated Identity Management (FIM)? Actually, we should be asking how important is FIM. It's the linchpin of digital convergence and probably one of the most important technologies of the modern era. Soon, we will begin to swim in digital television, multifunctional phones, devices of all kinds, and at the core of making all these things work together with our computer networks and the Internet lies identity management. At the core of identity management lies federation.

Are open source databases more secure?

If a recent Evans Data Corp. survey is any indication, IT administrators are increasingly worried about security holes in mainstream database products and are looking at open source alternatives. But John Andrews, president of the Santa Cruz, Calif.-based research firm, said that doesn't mean open source is necessarily better.
