Parental Peace of Mind

  The advent of the Internet, in some respects, made the job of parenting a little harder. We want our children to experience the vast wealth of knowledge available on the Internet and communicate with their friends online (frees up the telephone). Unfortunately, it also potential exposes our children to inappropriate material, obscene pop-up ads, and even sexual predators. In fact, research indicates that 1 in 5 children aged 10 to 17 have received a sexual solicitation over the Internet. This is definitely not something any parent wants to hear, but is forced to face. We need a little assurance that when our children access the web, they can do so safely. Internet filters are crucial to protect your children. One tool that can assist us in this goal is Internet Parental Control software. One of the top names in parental control software is ContentWatch, and if the Big Mouse himself recommends this product, then it has to be good. If Disney feels good enough to install th...

Why Do I Feel Like Somebody’s Watching Me?

  Spyware is one of the fastest-growing internet threats. According to the National Cyber Security Alliance, spyware infects more than 90% of all PCs today. These unobtrusive, malicious programs are designed to silently bypass firewalls and anti-virus software without the user’s knowledge. Once embedded in a computer, it can wreak havoc on the system’s performance while gathering your personal information. Fortunately, unlike viruses and worms, spyware programs do not usually self-replicate. Where does it come from? Typically, spyware originates in three ways. The first and most common way is when the user installs it. In this scenario, spyware is embedded, attached, or bundled with a freeware or shareware program without the user’s knowledge. The user downloads the program to their computer. Once downloaded, the spyware program goes to work collecting data for the spyware author’s personal use or to sell to a third-party. Beware of many P2P file-sharing programs. ...

Get Into the Zone

  Malware. An odd sounding word created to lump all malicious software programs, including viruses, worms, trojans, spyware, adware, and other malevolent codes into one cause-your-computer-serious-hurt category. In 2005, Computer Economics released a report on malware. The good news was that for the first time since 2002, the total worldwide financial losses from malware actually declined to a mere $14.2 billion. The bad news was that the nature of malware was changing from overt threats to more focused, covert attacks. This definitely is not great news for the average computer user just trying to keep up with the hundreds of malware programs that bombard us daily. It’s not an easy task keeping malware out of your computer system. In order to accomplish this, you need a strong antivirus program. One such program that can deliver the goods is ZoneAlarm Internet Security Suite 6 from Zone Labs. Zone Labs is one of the most trusted brands in Internet Security for good ...

What the Heck are Botnets?

  "A botnet is comparable to compulsory military service for windows boxes" - 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 t...

Who are the Players in the Antivirus Industry?

  Everyone in the United States has heard of the leading antivirus vendors Symantec, Mcafee, Computer Associates, and Trend Micro. These companies have market-leading presence in the United States. Microsoft, as well, has plans become a key player in this market. Microsoft acquired intellectual property and technology from GeCad software in 2003, a company based in Bucharest, Romania. They also acquired Pelican Software, which had a behavior based security as well as Giant Company Software for spyware and Sybari Software, which manages virus, spam, and phishing filtering. A lot of discussion has centered on whether Microsoft with come to own a dominant position in the antivirus market by simply bundling its technologies with its operating systems at no charge. This is a similar technique applied in other markets such as word processing and Internet browsers. Of course there are a number of antivirus vendors who also play in this market. There are many companies with great...

Website Security Rules of the Road

  In 2004, online consumer spending was at a record $65.1 billion. More and more people are attracted to the ease of online shopping and are spending higher amounts. Unfortunately, the chances of becoming a victim of Internet fraud are also increasing. The Internet National Fraud Center Watch reported that the average loss to fraud victims for just the first six months of 2005 was $2,579. This is compared to the $895 average for all of 2004. Complaints relating to general merchandise purchases (goods never received or misrepresented) accounted for 30% of Internet fraud complaints, and auction purchases (goods never received or misrepresented) topped the list at 44%. While many e-commerce Websites are reputable and have taken the necessary safety precautions to protect you, it never hurts to always proceed cautiously. If you are making an online purchase consider these easy steps: Use only one credit card, preferably with a low credit limit, when making online purc...

What are Intrusion Detection Systems?

  Intrusion Detection System (IDS) are a necessary part of any strategy for enterprise security. What are Intrusion Detection systems? CERIAS, The Center for Education and Research in Information Assurance and Security, defines it this way: "The purpose of an intrusion detection system (or IDS) is to detect unauthorized access or misuse of a computer system. Intrusion detection systems are kind of like burglar alarms for computers. They sound alarms and sometimes even take corrective action when an intruder or abuser is detected. Many different intrusion detection systems have been developed but the detection schemes generally fall into one of two categories, anomaly detection or misuse detection. Anomaly detectors look for behavior that deviates from normal system use. Misuse detectors look for behavior that matches a known attack scenario. A great deal of time and effort has been invested in intrusion detection, and this list provides links to many sites that discuss some o...

The Advancement of the Keylogger

  A keylogger is a program that runs in your computer’s background secretly recording all your keystrokes. Once your keystrokes are logged, they are hidden away for later retrieval by the attacker. The attacker then carefully reviews the information in hopes of finding passwords or other information that would prove useful to them. For example, a keylogger can easily obtain confidential emails and reveal them to any interested outside party willing to pay for the information. Keyloggers can be either software or hardware based. Software-based keyloggers are easy to distribute and infect, but at the same time are more easily detectable. Hardware-based keyloggers are more complex and harder to detect. For all that you know, your keyboard could have a keylogger chip attached and anything being typed is recorded into a flash memory sitting inside your keyboard. Keyloggers have become one of the most powerful applications used for gathering information in a world where encrypte...

Trojan Horse….Greek Myth or Computer Nemesis?

  We have all heard the term Trojan Horse, but what exactly is it? A Trojan Horse is a destructive program that masquerades as a harmless application. Unlike viruses , Trojan Horses do not replicate themselves, but they can be just as destructive. One of the most dangerous examples of a Trojan is a program that promises to rid your computer of viruses but instead introduces viruses into your computer. The Trojan can be tricky. Who hasn’t been online and had an advertisement pop up claiming to be able to rid your computer of some nasty virus? Or, even more frightening, you receive an email that claims to be alerting you to a new virus that can threaten your computer. The sender promises to quickly eradicate, or protect, your computer from viruses if you simply download their “free”, attached software into your computer. You may be skeptical but the software looks legitimate and the company sounds reputable. You proceed to take them up on their offer and download the softw...

Spam Buster

  Spam. Nobody likes it. Nobody wants it. No, we aren’t talking about the canned meat, but those unsolicited, unwanted, irrelevant, or even inappropriate messages that hit our email in mass quantities. While most mailboxes have some type of spam filtering software built into their system, they never seem to do a very good job of catching what you want them to catch, and letting through what you want them to let through. Therefore, it becomes increasingly important to turn to some type of additional spam filtering product. One such filtering system, designed for Outlook and Outlook Express users, is receiving rave reviews for its superior detection and low rate of false positives (i.e,. what you want to get through does). Cloudmark Desktop, formerly known as SpamNet and SafetyBar, uses a unique community-based filtering process. This community-based filtering system relies on users to report any new spam. Within minutes of a spammer being reported, they are placed on a b...

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 the...

Protection You Can Afford

  There are numerous ways you can lose the information on your computer. Your child decides to play Chopin on your keyboard, a power surge, lightening, a virus, or even simple equipment failure. Therefore, backing up the contents of your hard drive is an absolute MUST. By regularly making backup copies of your files and storing them in a separate location, you can typically get some, if not all, of your information back in the event your computer crashes. While a regular backup to floppy, CD, or zip drive will save your files, wouldn’t it be great if you could create an exact copy (a drive image) of your hard disk? That means backups of all your files, programs, and user settings. This would definitely save you time when it came to reloading. Acronis may be able to help. Acronis True Image 9.0 is a robust disk-imaging utility software that copies the entire contents of your hard drive including data and operating system files, personalized settings, and more, onto another...

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 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. Always make backups of important information and store in a safe place separate from your computer. 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 patc...

Phishing For Your Identity

  Who hasn’t received an email directing them to visit a familiar website where they are being asked to update their personal information? The website needs you to verify or update your passwords, credit card numbers, social security number, or even your bank account number. You recognize the business name as one that you’ve conducted business with in the past. So, you click on the convenient “take me there” link and proceed to provide all the information they have requested. Unfortunately, you find out much later that the website is bogus. It was created with the sole intent to steal your personal information. You, my friend, have just been “phished”. Phishing (pronounced as “fishing”) is defined as the act of sending an email to a recipient falsely claiming to have an established, legitimate business. The intent of the phisher is to scam the recipient into surrendering their private information, and ultimately steal your identity. It is not at easy as you think to sp...

How many spyware items are infecting your computer?

  I just had, by mistake, a plug-in called Intelligent Explorer attach to my browser. What a nightmare! I have another article on this topic, but this brings home a point. Spyware or adware items are continually infecting computers. Most computers have no protection from them. Most frightening is the frequency of them. From the InfosecWriters web site, "According to a 2004 survey by America Online and the National Cyber Security Alliance, 91% of users questioned were familiar with the term spyware. Only 53% believed their computers were infected, but a scan found that 80% of their PCs had some type of spyware installed on them." It goes on to say, "...The average number of spyware components per computer was 93 with one computer having well over a thousand." What is Spyware? Butte College ( www.bctv.butte.edu/support/spyware.html ) offers this definition: “The term ‘spyware’ is broadly defined as any program that gets into your computer without permis...

Name, Rank and Social Security Number

  Identity theft is the fastest growing crime in the U.S. The U.S. Secret Service has estimated that consumers nationwide lose $745 million to identity theft each year. According to the Identity Theft Resource Center, the average victim spends 607 hours and averages $1,000 just to clear their credit records. Identity thieves employ a variety of methods to gain access to your personal information. They may get information from businesses or other institutions by stealing it; by bribing an employee who has access to records; hacking into records; or conning information out of employees. Once identity thieves have your personal information, they may use it to commit a fraud or theft in your name. How can you tell if you have become a victim of identity theft? Some signs include unexplained charges or withdrawals from your financial accounts; bills or other mail stop arriving (the thief may have submitted a change of address); a credit application is denied for no apparent re...

Finding the Security Suite that meets your needs

  Before proceeding to read this article, it is important that we state something up front. It is essential for the reader to understand and appreciate that there is no such thing as a secure operating system or web browser . While the use of security suites and other complementing products can significantly reduce your risks, they are not magic wands that you can wave to eliminate 100% of your risk. Any product claiming they can do this should be viewed with great skepticism. With that being said, let’s talk computer security and security suites. There are numerous ways in which the security of your computer can be breached. The most common threats come from worms, viruses, Trojans, phishing, hackers and crackers. Potential security breaches can come in the form of downloading unfamiliar email attachments, being monitored by spyware, maliciously attacked by malware, or probed through port scanning. Dshield.org ( www.dshield.org ), a non-profit company, functions as...
