Easter Time. What it means to you.......

Hey all, im back again after being absent for a few months.

Now here is a topic that totally deviates from my techie nature........Food {mind you, i love good food, :-) }

Now that Easter has come and gone, what can we say was the best part of it.
Some will say that seeing family and friends; going places they have never been to before; getting well needed and deserved SLEEP (i got sum of this, hehe) me however......say that the food was and still is the best part.

Believe me, i can safely say that i got my fill of "bun" and still have space for more.
Now hold on a sec, let me explain sumthin for the 'foreigners' lol, in Jamaica, if someone says that u getting bun, it means that u are being cheated on, so dont mix them up.

I found this article on www.jamaicaobserver.com this morning, it seems interesting enough.


Anyways, will be back to post soon.

Taking a break from all the viruses and colds out there ^_^

5 Important Rules in Website Design


When it comes to your website, extra attention should be paid to every minute detail to make sure it performs optimally to serve its purpose. Here are seven important rules of thumb to observe to make sure your website performs well.

1) Do not use splash pages

Splash pages are the first pages you see when you arrive at a website. They normally have a very beautiful image with words like "welcome" or "click here to enter". In fact, they are just that -- pretty vases with no real purpose. Do not let your visitors have a reason to click on the "back" button! Give them the value of your site up front without the splash page.

2) Do not use excessive banner advertisements

Even the least net savvy people have trained themselves to ignore banner advertisements so you will be wasting valuable website real estate. Instead, provide more valuable content and weave relevant affiliate links into your content, and let your visitors feel that they want to buy instead of being pushed to buy.

3) Have a simple and clear navigation

You have to provide a simple and very straightforward navigation menu so that even a young child will know how to use it. Stay away from complicated Flash based menus or multi-tiered drop-down menus. If your visitors don't know how to navigate, they will leave your site.

4) Have a clear indication of where the user is

When visitors are deeply engrossed in browsing your site, you will want to make sure they know which part of the site they are in at that moment. That way, they will be able to browse relevant information or navigate to any section of the site easily. Don't confuse your visitors because confusion means "abandon ship"!

5) Avoid using audio on your site

If your visitor is going to stay a long time at your site, reading your content, you will want to make sure they're not annoyed by some audio looping on and on your website. If you insist on adding audio, make sure they have some control over it -- volume or muting controls would work fine.

Surfing the Web Anonymously – Questions to Ask

When you surf the web it is possible to learn information about you even when you don't want to advertise who you are. This is true even if your system contains no virus or malware software. Specifically information that is easily available online includes your IP address, your country (and often more location information based on IP address), what computer system you are on, what browser you use, your browser history, and other information. It gets worse. People can get your computer's name and even find out your name if your machine supports programs like finger or identd. Also, cookies can track your habits as you move from machine to machine.

How do people get this basic information about you?

When you visit another web site, information about you can be retrieved. Basically, information is intercepted and used by others to track your Internet activities.

How do you stop this from happening?

First of all, it is possible to serf the web anonymously and thereby stop leaving a trail for others to find. Note that this is not fool-proof, but it makes it much harder for people to know who you are. There are products called anonymous proxy servers that help protect you. The anonymous proxy server replaces your Internet address for its own. This has the effect of hiding your IP address and making it much harder for people to track you.


How do I get an anonymous proxy server?

There are many vendors who sell anonymous proxy servers. There are also free proxy servers available to you. Two such products are ShadowSurf and Guardster. Guardster (http://www.guardster.com/) offers various services for anonymous and secure access to the web, some paid as well as a free service. ShadowSurf (http://www.shadowsurf.com/) ShadowSurf provides anonymous surfing at their site for free. Go to it and you will find a box to enter a URL that you want no one to track. There are many others, but here are two that are frequently used.

Another interesting product, given the recent news about the Google search engine filtering its findings for the Chinese government, is Anonymizer (http://www.anonymizer.com). This company, among others, recently (Feb 1st, 2006) pressed that it "is developing a new anti-censorship solution that will enable Chinese citizens to safely access the entire Internet filter-free" (http://www.anonymizer.com/consumer/media/press_releases/02012006.html).

Does an anonymous proxy server make you 100% safe?

No. Still, you are much better off if you use such technology.

What other things should I be concerned about when trying to keep my private information private?

Three other items come to mind when trying to keep your information private. First, you can use an encrypted connection to hide your surfing. This article does not go into detail on this, but search the web and you will find a lot of information on this. Secondly, delete cookies after each session. Third, you can configure your browser to remove JavaScript, Java, and active content. This actually leads to limitations, so you need to think about the cost/benefit of this course of action.


Anything else?

Wishing you happy and safe surfing!

Securing Your Computer System

Today, more and more people are using their computers for everything from communication to online banking and investing to shopping. As we do these things on a more regular basis, we open ourselves up to potential hackers, attackers and crackers. While some may be looking to phish (Click HERE for definition) your personal information and identity for resale, others simply just want to use your computer as a platform from which to attack other unknowing targets. Below are a few easy, cost-effective steps you can take to make your computer more secure.

1. Always make backups of important information and store in a safe place separate from your computer.
2. Update and patch your operating system, web browser and software frequently. If you have a Windows operating system, start by going to
Windows Update (www.windowsupdate.com) and running the update wizard. This program will help you find the latest patches for your Windows computer. Also go to www.officeupdate.microsoft.com to locate possible patches for your Office programs.
3. Install a firewall. Without a good firewall, viruses, worms, Trojans, malware and adware can all easily access your computer from the Internet. Consideration should be given to the benefits and differences between hardware and software based firewall programs.
4. Review your browser and email settings for optimum security. Why should you do this? Active-X and JavaScript are often used by hackers to plant malicious programs into your computers. While cookies are relatively harmless in terms of security concerns, they do still track your movements on the Internet to build a profile of you. At a minimum set your security setting for the “internet zone” to High, and your “trusted sites zone” to Medium Low.
5. Install antivirus software and set for automatic updates so that you receive the most current versions.
6. Do not open unknown email attachments. It is simply not enough that you may recognize the address from which it originates because many viruses can spread from a familiar address.
7. Do not run programs from unknown origins. Also, do not send these types of programs to friends and coworkers because they contain funny or amusing stories or jokes. They may contain a Trojans horse waiting to infect a computer.
8. Disable hidden filename extensions. By default, the Windows operating system is set to “hide file extensions for known file types”. Disable this option so that file extensions display in Windows. Some file extensions will, by default, continue to remain hidden, but you are more likely to see any unusual file extensions that do not belong.
9. Turn off your computer and disconnect from the network when not using the computer. A hacker can not attack your computer when you are disconnected from the network or the computer is off.
10. Consider making a boot disk on a floppy disk in case your computer is damaged or compromised by a malicious program. Obviously, you need to take this step before you experience a hostile breach of your system.

A few Viruses to be aware of

This might be a somewhat old list, but i felt that the information will still prove to be valuable. This is by no means an all inclusive list. The best thing you can do is to remain vigilant, keep your anti-virus software updated, and stay aware of the current computer virus threats.

Virus: Trojan.Loader
A Trojan horse that attempts to download remote files. It will inject a .dll file into the EXPLORER.EXE process causing system instability.

Virus: W32.Beagle.CO@mm
A mass-mailing worm that lowers security settings. It can delete security-related registry sub keys and may block access to security-related websites.

Virus: Backdoor.Zagaban
A Trojan horse that allows the compromised computer to be used as a covert proxy and which may degrade network performance.

Virus: W32/Netsky-P
A mass-mailing worm which spreads by emailing itself to addresses produced from files on the local drives.

Virus: W32/Mytob-GH
A mass-mailing worm and IRC backdoor Trojan for the Windows platform. Messages sent by this worm will have the subject chosen randomly from a list including titles such as: Notice of account limitation, Email Account Suspension, Security measures, Members Support, Important Notification.

Virus: W32/Mytob-EX
A mass-mailing worm and IRC backdoor Trojan similar in nature to W32-Mytob-GH. W32/Mytob-EX runs continuously in the background, providing a backdoor server which allows a remote intruder to gain access and control over the computer via IRC channels. This virus spreads by sending itself to email attachments harvested from your email addresses.

Virus: W32/Mytob-AS, Mytob-BE, Mytob-C, and Mytob-ER
This family of worm variations possesses similar characteristics in terms of what they can do. They are mass-mailing worms with backdoor functionality that can be controlled through the Internet Relay Chat (IRC) network. Additionally, they can spread through email and through various operating system vulnerabilities such as the LSASS (MS04-011).

Virus: Zafi-D
A mass mailing worm and a peer-to-peer worm which copies itself to the Windows system folder with the filename Norton Update.exe. It can then create a number of files in the Windows system folder with filenames consisting of 8 random characters and a DLL extension. W32/Zafi-D copies itself to folders with names containing share, upload, or music as ICQ 2005a new!.exe or winamp 5.7 new!.exe. W32/Zafi-D will also display a fake error message box with the caption "CRC: 04F6Bh" and the text "Error in packed file!".

Virus: W32/Netsky-D
A mass-mailing worm with IRC backdoor functionality which can also infect computers vulnerable to the LSASS (MS04-011) exploit.

Virus: W32/Zafi-B
A peer-to-peer (P2P) and email worm that will copy itself to the Windows system folder as a randomly named EXE file. This worm will test for the presence of an internet connection by attempting to connect to www.google.com or www.microsoft.com. A bilingual, worm with an attached Hungarian political text message box which translates to “We demand that the government accommodates the homeless, tightens up the penal code and VOTES FOR THE DEATH PENALTY to cut down the increasing crime. Jun. 2004, Pécs (SNAF Team)”

Botnets Simplyfied

A definition can be found here Stromberg: (http://project.honeynet.org/papers/bots/)

Botnets are networks of computers that hackers have infected and grouped together under their control to propagate viruses, send illegal spam, and carry out attacks that cause web sites to crash.

What makes botnets exceedingly bad is the difficulty in tracing them back to their creators as well as the ever-increasing use of them in extortion schemes. How are they used in extortion schemes? Imagine someone sending you messages to either pay up or see your web site crash. This scenario is starting to replay itself over and over again.

Botnets can consist of thousands of compromised machines. With such a large network, botnets can use Distributed denial-of-service (DDoS) as a method to cause mayhem and chaos. For example a small botnet with only 500 bots can bring corporate web sites to there knees by using the combined bandwidth of all the computers to overwhelm corporate systems and thereby cause the web site to appear offline.

Jeremy Kirk, IDG News Service on January 19, 2006, quotes Kevin Hogan, senior manager for Symantec Security Response, in his article "Botnets shrinking in size, harder to trace", Hogan says "extortion schemes have emerged backed by the muscle of botnets, and hackers are also renting the use of armadas of computers for illegal purposes through advertisements on the Web."

One well-known technique to combat botnets is a honeypot(not Winnie The Pooh people, lol) . Honeypots help discover how attackers infiltrate systems. A Honeypot is essentially a set of resources that one intends to be compromised in order to study how the hackers break the system. Unpatched Windows 2000 or XP machines make great honeypots given the ease with which one can take over such systems.

A great site to read up on this topic more is The Honeynet Project (http://project.honeynet.org) which describes its own site's objective as "To learn the tools, tactics and motives involved in computer and network attacks, and share the lessons learned."
