Imagine having a form of windows that would run on the first versions of the P4 Intel Chip or on a Celeron, or the newer EEE’s and Ultraportables, wouldn’t that be a greener proposition than having to send tons upon tons of old computers to the recycling center (chips, computer chips are one of the most polluting products on earth due to the strict environment controls and exotic materials that are used in making them. The bad thing is that they’re so well made, recycling them to recover the precious metals can only be done through incineration to vaporize most of the packaging just to get to that precious couple of milligrams of silicon, lead or gold (plus many other exotic stuff they now use on these microprocessors).
Microsoft might still have it’s place in one of the most used Operating Systems but it’s time surely is numbered if they fail to follow suit on the open-system bandwagon which can have a basic web-server running on an old Pentium systems up and running in no time. Vista’s a flop (no doubt about it) and the announcement of a new OS from the software giant has put off more from shifting (even with the announcement of the mandatory phase-out of the selling of new machines bundled with XP). The genius of Bill might be needed (even though he has left the helm of the company again to come up with some concoction that would maintain the company’s grip on the industry it has so benefited from. “You see that light flashing in the corner of your eye? That’s your retirement light, and it’s flashing a bit faster every day)!!”

Many have been saying that time will come when the grip of Microsoft’s Windows on the market would be threatened by its own weight, the time is now. Gone is the time of the one size fit’s all philosophy and this is evident in their introduction from XP to Vista which not many prefer. The main reason, reliability of XP that has evolved since it was first introduced way back 2003. The OS has become so stable that it took the place of Windows 98′ as the preferred OS with all the right stuff in one neat package. That monopoly which has been held by the market is based on a one product fits all (through trim down versions and other editions such as the Media Center from 2005 which capitalized on the area of multimedia) This goes for all applications, from the home desktop, office laptop and desktops to server OS systems that are now feeling the crunch as people shift to more open-systems such as Ubuntu and Linux.
Why shift from a stable system developed by the industry’s largest and best developer, well, first they’re not the best anymore for the open-systems have gained ground allowing older PC’s to work at par as the latest multi-core driven computer systems. These alternate Operating Systems are developed and maintained by a group of industry experts and all users get to voice their needs and initiate changes according to relevance. The control Windows had with all the support and software updates coming from one big global company which sometimes doesn’t get what the user really wants (well, mostly really) has fed up most of us. Useless updates that make old systems slower, excessive overhead (in terms of disk space, memory and processor needs) and the notion that software drives the hardware development industry hand in hand rather than the hardware doing the same.

Some of these updates and patches are well publicized and known to media and IT circles while others are not. The real truth, not all users want to know the details of the several updates and patches that are being installed as long as they get to use the internet and other software without issues. This is a dangerous tightrope to walk for like the Facebook incidents and MySpace problems, and yes even Google (with their customer purchase tracking system which they took out of service as people took notice and were pissed they were being monitored as to shopping habits etc).

Even the most popular web search engines have come under fire when people took notice of their tracking systems and how that information is used to target them for advertising campaigns. The web is a true and proven signal of unparalleled freedom for it allows you to get information all with the press of a few buttons. But the battle begins at your desktop or laptop where the OS resides and is installed on making it the root of all possible problems. Yes, Attacks do come from the net but they are targeted at your home or office desktops using them as propagation tools to spread them all over the globe. Privacy and the right to know is quite battered on these fronts with many problems being discovered at every turn. People love intrigue and they will continue to scrutinize and criticize the work of others may they be friends or foes. On goes the OS wars and we are on the sidelines waiting to suffer all the fallout of their drive to be the first to release the most innovative and feature loaded software (with bugs and system crashes all bundled and included in the box, well till they release the respective fixes and patches to remedy them).

Everybody on this earth who uses the internet has to begin with a device (PC, Laptop or Mobile Phone) that has a form of operating system that gives the machine (computer/device) the ability to function as it does. May it be from Microsoft (Windows XP or Vista), Apple (OS X Leopard and prior versions) or Linux-Based operating systems, all these programs get their fair share of patches and bug fixes that are essentially damage control measures that hopefully correct programming errors before they cause too much harm to the user and the computer they are installed on.

These patches and updates are available for free for most licensed users but for those who still use bootlegged software, well, they are a bit too difficult to get hold of for the move of OS manufacturers to install (sometimes without you even knowing it), validation tools that check via the internet if the copy of your OS is licensed and legit. These underground updates are not always so discreet for some do get out and are found by users, programmers and other people who rely heavily on their computers for their everyday existence. Some get blown out of proportion sending them into the headlines as unwanted and unauthorized processes that you get to see on CNN and the BBC.

Software development firms are businesses and they do try their best to keep ahead of the pack (competitors) when it comes to the complexity and capabilities of their products. The competitiveness goes as far as the early release of a product before all testing and real-world simulations have been completed opting for patches and updates to correct them well after the product has been released into the wild (for public use). Some problems associated with them are so critical that the developers are so ashamed to admit they overlooked them that they opt to update these files without the user’s knowledge (have you ever seen your OS getting updates from the web as you get to go on your coffee break, sometimes so discreetly you even fail to notice, returning to a computer that tells you your system has been updated and a restart is needed for them to take effect?)

The complete commands and processes to which a computer operates cannot be covered in a day nor will be remembered in one sitting. Ideally, only the important things for consideration such as that of user friendly commands to allow proper interface between the computer and the user behind the keyboard will always be the only know-how that would remain.

Computer operating systems such as Linux and Windows offer a wide variety of benefits for people, especially in maximizing the capabilities of a computer and the installed software. Speed and reliability are among the important aspects that computer owner will always want and to be able to perform them, proper identification and references would need to be researched on.

It is a given that most people would not spend time studying all the aspects of a computer system. However, there will be instances when such accidental discoveries from exploring the computer operating system and its resources would ignite interest and push a person into further exploring information surrounding the issue and perhaps look at other benefits that operating systems provide but are not given much attention.

Most software tools that are used today are not perfect. Weaknesses and loopholes that may encounter system operation conflicts and problems will only be natural, especially for programs that are either not immediately compatible or are prone to breakdowns every now and then. The need for a continuous development as far as applying patches and updates towards such software, such as programming languages and operating systems like Windows and Linux, is a necessity.

This is only normal considering that chinks in the armor of anything will always be revealed at times when people least expect it. This is a continuing and ongoing trend that all software developers and administrators need to attend to, considering that as the height of demand for accurate programs are increasing, the same holds true for the need to provide features and flexibility on the programming aspect of installed systems for smooth flow of automations in most business organizations and entrepreneurial undertakings.

This is something that is not really new news but it is important nonetheless. For Linux users, there are certain things that you cannot do if you do not have what is called ‘root access.’ Basically, if you are not the super user or admin, you will not have access to certain commands.

Why restrict access?

There are certain applications which you would not want your users to install on their computers. Take for example peer to peer apps. If you allow your users the permission to install them, you could have some people sucking up the bandwidth. In a company wherein downloads of files from clients are important for your daily operations, this is a scenario you would like to avoid. If there are users with such apps, you would have to really trace them and monitor them so you would be able to cut down their internet access. Also, another thing is that they might unintentionally download some things that would let your system be infiltrated by worms and all that.

Sudo and sudoers
One way that you could give users a bit of access as admin is to put them in a sudoers list. Sudo is the command to let a user act as if he is the super user or root. The nice thing about it this is that there is also control as to which commands in particular could be run by certain users. If you will use create a list of sudoers, or those users who will have sudo access, you have to use visudo or sudoedit because there is a particular format for the /etc/sudoers file.

Novell would like to release a Linux with security management made easy according to the news on Security Focus. They have decided to not use security modifications by the National Security Agency because of the difficulty in configuring it. They have with it AppArmor though.

According to an article on Security Focus, the latest additions to SuSE Linux Enterprise Desktop (SLED) have been discussed in LinuxWorld. The focus was on AppArmor.

What’s up with AppArmor?

The AppArmor will be concerned with making access a bit more restrictive. There are some applications which need root access — these applications could make changes that would affect the entire system and if you want to make sure it would not happen, AppArmor could be the way for you to restrict access.

It is said to be that it is easy to use. Aside from that your system could be protected from internal and external attacks. This would be a plus factor, especially if you think about the costs of recovering from attacks that could affect your data.

How simple is simple?

• You have a name-based access control system.
• There is a graphical user interface.
• There are predefined profiles.
• There are wizards you could use to build security profiles for third party applications.

Check it out

Novell Linux is surely geared towards the users in the enterprise. If you want something that has a robust set of open source applications, a good user interface and tools, it is definitely one to try. You might not enjoy tweaking around too much and from the looks of things, SLED could be the Linux to give you an easy transition, in case you are migrating from proprietary to open source software.

There have been many flame wars, there have been different studies made regarding the security of each operating system mentioned in the title. The studies are sometimes said to be biased because it depends on what organization or company has funded the studies. At the end of the day, however, we must realize that no matter what operating system we use on our computers, we should be responsible enough to download security patches and the like.

Sometimes articles and threads on forums and blogs end up in fanaticism. Some of the points raised when it comes to vulnerability and operating systems would be:

The popularity of the operating system
Take for example Windows. It is probably the most popular operating system and some say that that is one of the main reasons why it is most attacked by hackers and creators of malware. They say that there is no point in attacking an operating system that is not used by many. The logic, they say, is that if you are going to do something, make sure it will be something big. (This is why there are people who seem to insist on getting a Mac — more stable and secure that way, as they say.)

Linux, BSD are operating systems that you can’t even run right away/properly/(insert phrase here)…
It sounds so petty, doesn’t it? But there are those who argue with Linux and BSD users that the difficulty with their operating system is that it is not easy to run it. Would an average computer users be able to use it and run it without much fiddling around? Truth be told, it looks like it is possible. But that depends on which Linux distribution you would run. In any case, the argument is more along the lines of “If you can’t even have the OS running properly, who would bother attacking it?”

Everyone must learn how to set up security measures. Be it setting up a firewall, being careful about which sites to check out, downloading patches — each of us will have different needs and we will have different experiences.
