Guide To Computer Security
Since you're reading this article, you're already connected to the Internet. You've probably already thought about security on your computer or network. Every day seems to bring new threats and it can seem pretty daunting, but the key thing is to have a common sense approach and to take a few basic precautions.
There are lots of great tools available to help and you don't have to break the bank to get them. Here are some areas to take a look at:
BACKUPS
Securing your information starts here. You'll need some or all of the security tools listed below, but even then you can't guarantee 100% that you won't have a problem. Hardware failures do occur so backup your data. One easy way to keep your important files is to burn them onto CD or DVD.
ANTIVIRUS SOFTWARE
An absolute must have. Alright, you already knew that, but I can't stress too strongly the importance of having good, up-to-date antivirus software. With new threats and Viruses arriving every day it's important to maintain update subscriptions and download virus definition updates as soon as they become available.
There's a lot of good antivirus software available, both free and for low cost. I'd recommend going for paid software...you just never know when you're going to need to call a helpdesk and that's generally the difference between the free stuff and the stuff you pay for. Norton, McAfee, AVG and others all sell antivirus software that's affordable on a low budget.
FIREWALL
A firewall is always recommended to help protect against unauthorized access to your PC. For a small number of PCs a software firewall is usually best and is the easiest to work with if you're not an IT expert. However, don't discount hardware firewalls, especially if you have a network with a lot of devices on it.
Whatever you do, don't rely on the Network Address Translation or packet filter built in to your ADSL or Cable router. It almost certainly won't be enough.
If you're buying a particular company's Antivirus software it's worth considering buying their integrated AV and firewall package if they have one (if they don't then maybe you should try someone else). It may well save you money and be easier to configure and maintain.
ANTI-SPYWARE SOFTWARE
If you spend a lot of time browsing the Web (and let's face it, who doesn't?), then spyware is going to find its way onto your machine. A lot of it isn't particularly nasty, but the really bad stuff can send important information like passwords, bank details or credit card numbers to people you really don't want to have access to that stuff. At the very least it can slow down your PC and since you didn't ask for it in the first place then you should get rid of it.
Some tell-tail signs that you have a Spyware infection are:
- You're getting pop-up ads all the time
- Your default homepage or other settings in your browser suddenly change (especially if you can't change them back)
- Your computer is slow (there could be other reasons for this, but it's worth checking for spyware)
There's some good free software available from Lavasoft called AdAware. Microsoft also have their own free tool for Windows users called Windows Defender. Among the paid-for Anti-Spyware software Webroot's
Spy Sweeper regularly picks up awards from computer magazines.
PASSWORDS
More and more people are accessing secure sites for shopping, banking, etc. Provided you take sensible precautions it's a great way to shop.
If you've been doing any online shopping you'll be used to dealing with secure sites. Whatever methods these sites use to secure their servers or encrypt your traffic, if they're accessed by passwords then you share some of the responsibility for the security on your transactions. Here are a few tips on how to keep unauthorised users from accessing your accounts:
- Be inventive with your passwords. Don't use easy to guess stuff that a lot of people know about you or can find out. Use a mixture of uppercase and lowercase characters, numbers and special characters (again be inventive. Just using a 1 instead of the letter i is no use if it still spells out an easy to guess word).
- Use different passwords for different accounts. If you always use the same one and it's compromised then someone will have access to everything.
- Don't write passwords down on paper or post-it notes. That's a hacker's favourite way to find passwords if they have physical access to your office.
- Don't get Web browsers to remember your passwords on shared machines or in office areas. If you log into a machine that other users have access to then never use Windows or Web browser mechanisms that remember your account details.
Having different passwords to lots of different accounts does make it more difficult to remember them and it's important that this doesn't lead you into bad habits. So what do you do?
You could look at getting some password management software. Naturally, Norton has a password manager, but other good options include "Web Replay" from Deskperience or "PC Password Manager XP" from CPLab.
WHERE TO NOW?
You don't have to go out and buy every piece of security software right away. Prioritise one or two to start with (I'd suggest Antivirus and Firewall software). Also download trial versions so you can be sure you're happy with them before you part with your hard earned cash.
Be careful on the Internet, but don't let it spoil your day.

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 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 www.windowsupdate.microsoft.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.

Computer Virus And Internet Worms Explained
Is your computer sluggish? It won't open programs and you can't get into anything? Well, maybe you have a sick computer. Just as people get ill from viruses, so do computers. When this happens, you need to have a computer technician look at the computer to re-format and get rid of the virus. If you know something about computers, you might be able to do this yourself.
What is a Virus?
A virus is a parasitic program written to intentionally enter a computer without the user's permission or knowledge. The word parasitic is used because a virus attaches to files or boot sectors and replicates itself, which allows it to spread. Though some viruses do little more than copy themselves, others can cause serious damage or affect program and system performance. A virus should never be assumed harmless or left on a system.
Types of viruses
Viruses are classified by the ways they infect computer systems:
1) Program: Executable program files such as those ending with the extensions .Com, .Exe, .Ovl, .Drv, .Sys, .Bin
2) Boot: Boot Record, Master Boot, FAT and Partition Table.
3) Multipartite: Both program and boot infector.
What is Trojan Horse?
Besides being a large wooden horse used in the Trojan war 2500 years ago (and more recently by Brad Pitt), a Trojan Horse or Trojan is a computer program that seems innocuous or harmless, but conceals another more nasty function. Generally a Trojan is contained in a part of program brought into your computer from an outside source - (e.g. floppy disk, CD, internet download, infected email). Trojans can be dangerous sometimes. For example a program may appear to be a computer game demo, but while you enjoy the game, it may be happily formatting your hard disk or emailing porn sites to everyone in your email address book.
Trojans are also used as a 'back door' or 'trap door' to sneak into a computer's operating system's information. An example is a program that pretends to be the system log-in program (such as you find in Windows NT/XP or Linux). When an unsuspecting user tries to log-in, the Trojan program captures the user-name & password. Then it may indicate a failed log-in attempt and exit to the real log-in program. The user may successfully log into the system next time, but by that time Trojan has also got enough details to log into the system.
Example Trojans
Notroj. This Trojan horse pretends to be a program that guards against Trojans. It's actually a time bomb that wipes out the hard disk after it's more than 70 percent full.
PWSteal.Refest A Trojan Horse that installs itself as a BHO (Browser Helper Object) for Internet Explorer and steals online banking information when it is submitted in web forms.
PWSteal.Likmet.A A Trojan horse that displays a fake MSN Messenger logon window and steals the password provided.
Run.me. This is a graphics program, which plays the Star Spangled Banner and displays the American Flag while it worms its way into the hard disk and erases the data on it.
What is Worm?
A Worm is a self-propagating program that works its way through a system or network (like the Internet), often causing damage. It does not require a host program to activate it. Someone has to insert a worm directly into network of interconnected computers where messages can be sent from one to another and data files and programs exchanged. An example is a local area network where each computer has its own files, programs operating systems and hard discs such as would be found in a university or corporate setting.
Example Worms
Alarm Clock Worm. A worm that reaches out through the network to an outgoing terminal (one equipped with a modem), and places wake-up calls to a list of users.
Worm Watcher. A special program which automatically takes steps to limit the size of a worm, or shut it down, it grows beyond a certain limit. The worm watcher also maintains a running log recording changes in the

What is Trojan Horse?
Besides being a large wooden horse used in the Trojan war 2500 years ago (and more recently by Brad Pitt), a Trojan Horse or Trojan is a computer program that seems innocuous or harmless, but conceals another more nasty function. Generally a Trojan is contained in a part of program brought into your computer from an outside source - (e.g. floppy disk, CD, internet download, infected email). Trojans can be dangerous sometimes. For example a program may appear to be a computer game demo, but while you enjoy the game, it may be happily formatting your hard disk or emailing porn sites to everyone in your email address book.
Trojans are also used as a 'back door' or 'trap door' to sneak into a computer's operating system's information. An example is a program that pretends to be the system log-in program (such as you find in Windows NT/XP or Linux). When an unsuspecting user tries to log-in, the Trojan program captures the user-name & password. Then it may indicate a failed log-in attempt and exit to the real log-in program. The user may successfully log into the system next time, but by that time Trojan has also got enough details to log into the system.
Example Trojans
Notroj. This Trojan horse pretends to be a program that guards against Trojans. It's actually a time bomb that wipes out the hard disk after it's more than 70 percent full.
PWSteal.Refest A Trojan Horse that installs itself as a BHO (Browser Helper Object) for Internet Explorer and steals online banking information when it is submitted in web forms.
PWSteal.Likmet.A A Trojan horse that displays a fake MSN Messenger logon window and steals the password provided.
Run.me. This is a graphics program, which plays the Star Spangled Banner and displays the American Flag while it worms its way into the hard disk and erases the data on it.
What is Worm?
A Worm is a self-propagating program that works its way through a system or network (like the Internet), often causing damage. It does not require a host program to activate it. Someone has to insert a worm directly into network of interconnected computers where messages can be sent from one to another and data files and programs exchanged. An example is a local area network where each computer has its own files, programs operating systems and hard discs such as would be found in a university or corporate setting.
Example Worms
Alarm Clock Worm. A worm that reaches out through the network to an outgoing terminal (one equipped with a modem), and places wake-up calls to a list of users.
Worm Watcher. A special program which automatically takes steps to limit the size of a worm, or shut it down, it grows beyond a certain limit. The worm watcher also maintains a running log recording changes in the

Computer Security – It’s Bigger than Spyware and Viruses
Computer security, in basic terms means keeping your computer and the data that’s in it safe and secure. More of our personal data is stored in or accessed from our computer, now more than ever before. Yet most people lack even the basic understanding of how to keep their computers safe and secure. By following just a few simple rules you can dramatically improve the overall security of your computer.
The first thing to understand is what exactly it means to be connected to the internet. Your computer connected to the internet is similar to your house in many ways. There are many ways into your house. Windows, doors, etc. The more windows and doors you have, the more ways someone has into your house. An open door doesn’t necessarily mean you are going to be robbed, but it does improve the chances. Complicating matters, the ones that you think are locked, may not be because the lock is faulty or even the door itself may have an as of yet undiscovered flaw that would allow an intruder easy access to your home.
Your computer has many windows and doors, not all of which are locked. New flaws are being found everyday, often with the fix not coming until days after. Just like you wouldn’t leave your front door unlocked, you shouldn’t leave your computer wide open either. The first two things we will discuss to help with this task are installation of a quality firewall and regularly updating your installed software.
Updating your software is becoming easier these days, especially your Operating System. We don’t have the time here to go into detail about the many ways to update the many software packages you may have or use, but generally speaking the software manufacturer will provide you a way to do this automatically via the internet. A good example of this is the Microsoft Windows Update feature. Be sure to get the updates for everything installed on your computer, nothing is too trivial.
There are two basic types of firewalls and both perform the same functions. One is hardware the other is software. A hardware firewall is probably included in your router if you are using one, while you may or may not have a software firewall installed. To continue our house analogy, a firewall is like building a wall and gate around your home and giving the guard at the gate instructions on who to let in and out. While this does give a great deal of protection, it is not all that is required. Someone may know a way around or under your wall, or even be able to coerce the guard into letting them in.
You yourself may unwittingly allow someone in. This could happen by simply opening an email or even simply surfing the net. Spyware, viruses, trojans and the like are ever more adept in their methods of fooling you and your guards. Emails may come from a trusted friend containing a dangerous virus without them even knowing it. This is where the next layer of protection comes in, anti-virus software.
Anti-virus software is a large category these days. Often these packages come as “suites” including a firewall and Spyware scanner. While most of these programs are very effective in their promised tasks, it is not wise to be lulled into a false sense of security by them. They are simply one layer in what should be a multi tiered protection plan for you and your computer. One last important note about anti virus software is to be sure that it updates on a regular basis. New threats come out daily so check its updates manually to be sure they have happened.
Back to our house analogy, we now have all of our windows, doors and other entry ways locked and fully updated. We have a wall around our house with a guard at the gate and we have software scanning everything that comes in past the gate. Sounds pretty good, but there’s one last security hole we need to address, you.
A large percentage of infections are caused by the computer user themselves. The internet is an ever changing place that requires it’s users to be educated about its use. I’m not suggesting that you need to be a computer expert to simply read your email. I am however suggesting that you take some time to educate yourself on some of the dangers that pop up everyday, and the precautions to take in order to avoid them.
In summary, your computer is a powerful machine connected to one of the greatest things ever invented, the internet. This vast resource can be a dangerous place if you are not properly prepared and informed. Regular software updates, a good firewall, anti virus software and a little education are the basics in computer security. Having and understanding these basics will make your computer safer, more secure and more enjoyable.

Phishing with a Net
When geeks gave us the Internet and the means to use it, they also gave us a new segment of vocabulary ...
I've often thought it a shame that a few of them didn't make their way to a campus literature or marketing department and see if a student of poetry or sizzle could assist them in assigning names to their innovations. For example, did the manual cursor operator have to be called a 'mouse?'
Geeks have overtaken sports-speakers when it comes to coining bad phrases. I've never understood why basketball types say a player 'kicks out' a ball to a teammate on the perimeter when his feet never touch it. Worse yet, I've always wondered if a gridiron football player would really want to dive on the ball if the carrier truly 'coughed it up!' That bit of literal imagery is more revulsive than handling a mouse. Do these guys really think about what they're saying?
There is one instance, though, where the geeks thought it through and got it right. 'Phishing' is a perfect connotation for cyber-cons who troll for prey.
The word's spelling distinguishes this nefarious activity from a sporting endeavor, but it's still a game. The definition that's been developed for it is "a technique used to gain personal information for purposes of identity theft, using fraudulent e-mail messages that appear to come from legitimate businesses. These authentic-looking messages are designed to fool recipients into divulging personal data such as account numbers and passwords, credit card numbers and Social Security numbers."
Another term that alludes to the emotive consequences of cyberobbery is the perjorative sense of 'hacker.' That bit of etymology seems to be a work in progress. The accepted definition refers to "individuals who gain unauthorized access to computer systems for the purpose of stealing and corrupting data." However, the added qualifier is, "Hackers, themselves, maintain that the proper term for such individuals is cracker."
Being hacked or being cracked makes little difference to those on the receiving end. They just know they've been had. Understandably, their first impulses are to get mad and want to vent. My contention is that, most of the time, they're lashing out in the wrong direction. After all, crooks are crooks; that's their job and they're out there in numbers. That's not going to change anytime soon.
These victims need to take a hard look at themselves.
The economics of law enforcement --- in cyberspace or elsewhere --- limits what can be investigated and prosecuted. Thus, smart spoofers often keep their 'take' per scam campaign at levels sufficiently low that the cost of prosecuting them is not viable. Then, they change their coordinates, plus their identities, and do it again.
So, obviously, the most important factor in cyber-diligence is self-precaution. Most steps are basic, as evidenced by the checklist on the USA government's Federal Trade Commission website:
"If you get an email or pop-up message that asks for personal or financial information, do not reply. And don’t click on the link in the message, either. Legitimate companies don’t ask for this information via email. If you are concerned about your account, contact the organization mentioned in the email using a telephone number you know to be genuine, or open a new Internet browser session and type in the company’s correct Web address yourself. In any case, don’t cut and paste the link from the message into your Internet browser — phishers can make links look like they go to one place, but that actually send you to a different site.
"Use anti-virus software and a firewall, and keep them up to date. Some phishing emails contain software that can harm your computer or track your activities on the Internet without your knowledge.
"Anti-virus software and a firewall can protect you from inadvertently accepting such unwanted files. Anti-virus software scans incoming communications for troublesome files. Look for anti-virus software that recognizes current viruses as well as older ones; that can effectively reverse the damage; and that updates automatically.
"A firewall helps make you invisible on the Internet and blocks all communications from unauthorized sources. It’s especially important to run a firewall if you have a broadband connection. Operating systems (like Windows or Linux) or browsers (like Internet Explorer or Netscape) also may offer free software 'patches' to close holes in the system that hackers or phishers could exploit.
"Don’t email personal or financial information. Email is not a secure method of transmitting personal information. If you initiate a transaction and want to provide your personal or financial information through an organization’s website, look for indicators that the site is secure, like a lock icon on the browser’s status bar or a URL for a website that begins 'https:' (the 's' stands for 'secure'). Unfortunately, no indicator is foolproof; some phishers have forged security icons.
"Review credit card and bank account statements as soon as you receive them to check for unauthorized charges. If your statement is late by more than a couple of days, call your credit card company or bank to confirm your billing address and account balances.
"Be cautious about opening any attachment or downloading any files from emails you receive, regardless of who sent them. These files can contain viruses or other software that can weaken your computer’s security.
"Forward spam that is phishing for information to spam@uce.gov and to the company, bank, or organization impersonated in the phishing email. Most organizations have information on their websites about where to report problems.
"If you believe you’ve been scammed, file your complaint at ftc.gov, and then visit the FTC’s Identity Theft website at www.consumer.gov/idtheft. Victims of phishing can become victims of identity theft. While you can't entirely control whether you will become a victim of identity theft, you can take some steps to minimize your risk. If an identity thief is opening credit accounts in your name, these new accounts are likely to show up on your credit report. You may catch an incident early if you order a free copy of your credit report periodically from any of the three major credit bureaus."
If you use e-currency or e-payment services, be aware that they are usually not liable for any of your losses if you've been hacked or cracked due to identity-theft issues. All reputable services have support divisions that investigate any complaints of spoofing --- for example, Paypal asks you to mail them at spoof@paypal.com if you receive a suspicious message using their name --- and if anyone is going to pursue, or at least keep on file, complaints of any amount, it will be them.
Virtually all e-currency services offer options of 'virtual' keyboards for logging in to accounts. They may be a bother, but they are very effective at adding a formidable obstacle for cyber-invasion. Then, whether or not you took this step to access your account, make sure you take the time to actually log out of your account, as opposed to merely clicking away to your next site.
I note that the Longer Life site has two very good preventive products as sponsors, Kaspersky Labs and Identity Guard. They are first-class products and well worth your while to consider.
This stuff doesn't take long to research or to implement and you don't have to be a geek to do it. You don't even have to know their their terminology. Instead, when you're done, you can confidently refer to a familiar term in both sports and banking:
Safe.
