Who is the safest operating system?
Windows XP in the endless stream of security vulnerabilities allow many users to start thinking about whether to change to another more secure operating system.
Linux advocates constantly preach the open source operating system more secure than Windows, and Microsoft's natural resistance to the idea. Open BSD (a free version of Unix, www.openbsd.org) claims to be the world's most secure operating system, and its most important feature is the integration of memory protection and encryption. In fact, there is no 100% security operating system in the world. It is a myth that there is no bug in the extremely complicated software of the operating system.
In the field of desktop PC applications, operating systems usually do not consider security as a primary consideration, they will consider more ease of use and feature richness. It is not worthwhile to abandon Windows to other operating systems just because of concerns about security issues. Linux and Mac OS also have vulnerabilities and require frequent patch upgrades.
The company promises to provide a more secure protection mechanism in the next version of Windows XP, Longhorn. The current controversy is whether Longhorn's virtual machine concept really allows Windows users to get a safer environment. The same controversy exists for the Vanderpool virtualisation architecture that Intel will adopt in future processors. The advantage of a virtual machine is that it runs the operating system on a secure virtual PC, isolating the real system hardware, making it difficult for the virus to penetrate deep into the system for damage.
How much protection does your computer need?
For better security, you should first take advantage of the built-in features of the operating system: install the latest security patches and properly configure the operating system and Internet browser security options. You don't need to install expensive spyware search tools or anti-trojan tools, because a good anti-virus software tends to provide a safer operating environment than them. If you still want to install a separate anti-trojan tool, consider those free tools, such as the Ewido Security Suite (www.ewido.Net). The same is true for anti-advertising and spyware tools. Good anti-virus software already provides such functionality. If you have to install it, consider free software such as Ad-Aware (www.lavasoft.com) and Spybot. Search & Destroy (www.safer-networking.org)).
anti-virus software must be installed, and we also need a good Internet firewall, because everyone needs online. Even if you only have two computers, we recommend that you use a router with a built-in firewall, preferably a firewall with Stateful Packet Inspection (SPI), which minimizes the damage of malicious programs.
In addition, you need to install a good anti-spam tool to remove a lot of spam and avoid clicking on dangerous links. Spambully (www.spambully.com) is a good choice if you use Outlook or Outlook Express. It's highly customizable and can filter 98% of spam, which is worth a $22 to buy it. Another tool you can choose from is Mailwasher (www.mailwasher.Net), which works for any e-mail client, but at a slightly more expensive price ($37).
avoid falling into the "trap of fake"
to cheat the user's private information by mimicking a legitimate website there are more and more cases of the trend. There are three basic rules that can help you avoid falling into "falsification traps":
Keep your mouth shut: Remember, any ISP, online store, or dysentery 苈耄 苈耄 苈耄 苈耄 苈耄 貉≡窳 ! ! ! ! ! ! !
Ignore links: If you really want to access the link shown in the e-mail, you can manually enter that URL in your browser instead of clicking on the link directly, because that is probably not the case. Go to the displayed URL.
check the details: The URL provided by others to double-check the spelling correct, if in doubt, would rather make a phone call to confirm the company's customer service department.
Protect your hardware
If you have important data stored in your PC, is it getting enough physical protection? Consider the following questions:
Building: Is your PC in a closable area? Will the office be locked in time when no one is there?
Paper: Is the paper with important information printed in time or directly thrown into the waste paper basket?
Network printer: Is the network printer located in a public area, is there someone else who can take the printed document from there?
Thief: Can visitors take the computer away from the company without checking?
Mobile devices: Is the information in laptops, PDAs, and smartphones encrypted?
Access: Can other people in the room start your computer and implant a Trojan horse program? Is your chassis locked?
Access: Does your BiOS use password protection?
access: local area network whether user rights were clearly defined?
Disk: Has the disk been thoroughly deleted before it was discarded?
Top 10 Tips for PC Security
Many users still underestimate the need for PC security protection, according to AOL research and from the National Cyber Security Alliance (NCSA). A survey report (www.staysafeonline.infonewssafety_study_v04.pdf) indicates that 67% of respondents did not install any anti-virus software or failed to update their virus definition files in a timely manner. And 90% of PCs have been spyware, and 63% of users have not used any Internet firewall.
After answering the following 10 questions, you will know if your PC is safe.
1. Have you installed anti-virus software and can update its virus definition files in time?
2, if you have an Internet firewall and configured properly or activation?
3, if you take advantage of a variety of options to ensure the security of Internet Explorer and Windows (such as automatic update options and Windows Security Center)?
4. Have you installed anti-spam tools and are alert enough to e-mail and pop-ups with clickable links?
5, your personal password is strong enough and not easily guessed, whether to use a different account when people use a computer?
6, you like all kinds of unreliable software downloaded from the site easy to introduce spyware?
7, if you have enough knowledge of the dangers of viruses and hackers?
8, if your WLAN using WPA encryption mechanism?
9. Is there an operating system that is not needed on your PC?
10, whether your privacy or data encryption to protect e-mail? Is the system backed up?
