What are Laptop and Notebook Anti-Theft Devices?

Kensington_lock_for_Notebook_LaptopWhile the improvement in laptop technology and portability means that more of us have access to mobile computing power than ever before, laptop theft remains an important concern. However, along with an increase in power and storage capacity, many gamer laptop manufacturers have also developed some innovations in laptop security and anti-theft technology. While there are many methods that are used to protect laptops, including alarms, locks, and software protection, the most popular anti-theft device that is included on most laptops is a Kensington security slot.

Kensington Locks

A Kensington security slot is sometimes referred to as a K-Slot or a Kensington lock and is included by various manufacturers on many different laptop designs. It is comprised of a small hole that is reinforced by metal, and is used for the attachment of various lock-and-cable devices. Some manufacturers, including Kensington themselves, make these locking devices, which often use a key or combination system that is attached to a rubber-metal cable. The end of the loop that is not attached to the computer can be looped around any permanent object, such as a piece of furniture or a part of a building or other structure. As well as being used by individuals for the protection of their own laptops, a number of electronics stores also use these devices to secure their laptop stock.

There are other manufacturers who have developed alternative laptop security products, some of which do not require a special locking hole. While not as strong as a Kensington lock in most situations, they do have the advantage of being much more versatile. These locks can be attached to popular laptop ports such as VGA ports or printer ports, and so do not require a dedicated security slot configuration. Along with Kensington locks and similar physical devices, other aspects of laptop security include alarms and various methods of software protection. While software protection may not stop the physical theft of a mobile computer device, it can be very good at restricting access to the data inside. While anti-theft technology was once only seen on gamer laptop computers and other expensive machines, it is now a common feature on most notebooks.

Spam Prevention for the Linux Operating System

linux trainerThe Linux operating system is a family of different OS distributions that are based on Unix. While only used by a relatively small proportion of computer users, Linux does have a strong community of both users and developers.  is probably the biggest example of free and open source software development in the world, and the culture that surrounds Linux is very different to the closed corporate approaches of both Microsoft and Apple. While the Linux computer community enjoys some advantages in terms of security and spam prevention, a variety of general and speciality security solutions are developed for use on Linux operating systems.

Linux Security and Spam Prevention

Like all computer users who access the Internet, spam is a huge problem. While estimates do vary greatly, some studies have shown up to 90% of received email to be spam-like in nature. Because Linux users often use dedicated Linux email applications, dedicated spam solutions are often required. Some the large commercial Internet security and spam prevention applications can be installed on Linux systems, with some companies like Kaspersky developing Linux computer versions of their popular software.

Along with the general anti-spam filters on web-based mail servers, there are also many open source programs that run solely on Linux mail servers. Many of these applications are included with distributions of Linux operating systems, with others available to download online. While specialty Linux spam solutions will be needed by anyone who is using a Linux mail server, for most people using a web-based mail server, universal solutions are often all that is required

However, while spam may be an issue for all Internet users despite their operating system of choice, many security experts talk of the inherent advantages of using the Linux OS. According to many researchers around the world, the monoculture of Windows and its tight binary compatible system mean that malware exposure is more extensive than more loosely coupled Linux distributions. However, in terms of spam prevention, the differences are not so clear cut, as spam is an Internet-based problem that does not discriminate between operating systems.

What is Sharepoint Used For?

Share-Point2015While Sharepoint is certainly not the only blogging platform susceptible to the problems of spam, its architecture does not help the problem. Sharepoint is a software platform developed by Microsoft specifically for web publishing and file sharing, although it is not optimised specifically for this task.

While many people use Sharepoint for blogging, some of its other uses include wiki development, website development, and content management. This broad range of different applications is one of the reasons why Sharepoint blogs are not very good at dealing with spam. Sharepoint has no spam prevention out-of-the-box, and protection needs to be implemented by users through various techniques.

One popular method is to use the data view to delete many items of spam at once, by using the Sharepoint data grid and deleting numerous rows at a time. While this is an efficient way to delete spam once it has already been uploaded, it is also a good idea to use a CAPTCHA mechanism to block spam before it is uploaded.

A lot of spam is uploaded in an automated fashion, so a CAPTCHA is a great way to cut dramatically down on spam. Custom workflows can also be made to delete spam, and column entry procedures can be set up to act as a home made CAPTCHA mechanism. While Sharepoint is a powerful blogging system, it is often necessary to set up these kinds of filters and conduct these kinds of manual spam deletion techniques.
