Biometrics + Physical security = Next best thing to unbreakable?

Written by Saran on July 13, 2011

Biometrics is seen as the next step in computer systems security and access control due to the failure of more primitive and fundamental security systems. Fingerprint scanners, passwords, security keys and even smartcards have failed miserably in providing the ultimate and most secure intrusion prevention method for just about anything. From your home, car, computer terminal at work to just about anything else that needs security, it has be come more and more of a must due to the increasing threat of identity theft and other computer related crimes in and out of the workplace.

Biometrics are security systems that are based on the differences the human body manifests in terms of eye structure, facial features and now vein geometry. We’ve all heard of DNA or the so-called blueprint for life and the way it makes each and every human different from everyone else on this earth (well, except for some genetic disorders and diseases that changes the DNA makeup). That is what biometrics takes advantage of as a source of a very unique key or method of identifying one from another person.

Your fingerprint is mapped when it is initially scanned into a computer system which convert’s your analog (actual) print into a digital map that is as unique as you are an individual. Iris scanners take into account the differences the iris has from each and every individual (through the use of a low powered light and scanner to obtain a picture of the eye’s iris which is also unique). Voice recognition takes into account, the differences our voices have from everybody else also converting it into a digital map or password of sorts. Vein geometry, uses a thermal imaging camera to take a picture of your hand or whole body which is sensitive to heat showing all the blood vessels which show as hotspots thus giving you a unique id of sorts as that is also mapped and converted into digital form. All of the above biometrics systems rely on our individual differences which are quite unique to us and add onto it, other more basic security measures such as a physical key (password, key or other devices) to give the ultimate security system preventing intrusion.

How to Handle a Virus

Written by Saran on June 28, 2011

One of the common problems that PC owners have these days is finding out that they have a virus residing in their PC. Don’t be comforted by the fact that you have an anti-virus software running. Viruses will always find a way. Also, if you do have one, are you sure it is licensed?

Apparently, most people fail to realize the value of a good anti-virus software when it comes enabled with all the features included. Some are fine with the trial version as long as they are protected. At least that is what they think. But the real value of a good anti-virus software comes out when you get the full version that comes with the actual cleaning tool when you get one officially.

For most trial versions, you may be surprised to note that once they are able to detect a certain virus, you can only discover them but not clean them. If you do try to clean them, it will tell you to get the full version at a certain price of course.

There are some software that clean certain viruses but these are mostly low in threat. But the graver ones are the issues you have to content with. If you really want a fully protected PC, chances are you better consider an investment that can really protect you from such virus issues, most of which can really hurt you as far as computer files and documents are concerned.

The Price for Downloading Cracked Software

Written by Saran on June 21, 2011

Whether you are downloading a trialware or files from Bittorrent, the chances of cracking or using the full version has severely dwindled in the past months. For one, other than possibly downloading infected software with Trojans and malware, unlocking these supposed protection software has taken a bad hit by the advanced efforts of private software companies to crack down on piracy.

Take for example Kaspersky Internet Security 2009 which has cracked the whip on licenses by blocking them once you start updating the software. While you can install and crack them, they are rendered useless in the end since once you hit that update option, your key is automatically blocked. Worst, malware and Trojans start coming in (a scenario which I don’t understand if it was made on purpose by the vendor in sending malware) infecting the systems folder where Windows is installed.

Before you know it, dozens of files in the form of dll’s start showing and mind you, they are dangerous. So if that was the case, it makes you think if you were better off not using an anti-virus software at all.

But such is the price to pay for trying to pull a fast one. Everyone loves free things and free software is surely to be an eye-catcher. But if the return is tons of viruses and malicious programs that can wreck your computer, you better think twice before downloading them again.

Backups: Be Ready for Anything

Written by Saran on June 14, 2011

Backing up your files is a routine practice that most people fail to appreciate at times. Well for one, it takes an instance where sudden system malfunctions or intrusions to learn the value of having properly backed up files for people to appreciate its routine. Normally, thanks to the strict and professional efforts that assigned information technology personnel, common users rarely have to worry about losing their work and saved files since these people in the front end, already make sure that any untoward intrusions or risks can even enter their computer network and workstations.

Regardless though, all computer users are encouraged to make sure that they maintain separate data backup files for security reasons. Experiencing such issues where your computer suddenly goes on the blink is a serious issue that may even lead you to cram and worry since in most cases, losing important files such as reports and documents can hamper you and your role in the standard operations of carrying out work.

So while it does seem like such an effort points to nonsense. But while that may seem the case for now, it is by no means a reason for anyone to take it easy and take backups for granted. It is a routine task and while many don’t do it regularly, such people should not leave such a task entirely to the responsibility of the IT people.

Besides, knowing how confidential some files are, being assisted once or twice is enough. But over that is already a sign of laziness and for sure is a clear sign that these people have no intentions of adding that task to their list of duties and responsibilities.

Cyber Wars: A Lost Cause

Written by Saran on June 7, 2011

We know for a fact that the battle towards malicious software and viruses released on the web has caused a lot of pain as far as pinpointing and remedying them but apparently nothing has been done to really resolve them. We buy licensed software but we have to ask ourselves on the extent of their coverage. Are they up to date and can they really save us from all these uncertainties of getting online?

Microsoft has been a prime target, being one of the widely used operating systems we know of today. But while Bill Gates and company are doing their part in being able to address the various intrusions and headaches that they can do with a simple click, you just don’t know who to trust these days. Even the software companies have the ability to manipulate and do some foul work and they are occurring right under our very noses.

Security researchers concede that their efforts are largely an exercise in a game of whack-a-mole because botnets that distribute malware like worms, the programs that can move from computer to computer, are still relatively invisible to commercial antivirus software.

So with all these things set on the table, is the cyber world safe for anyone? We can fend off threats but the question is are we resolving the situation or merely providing a temporary solution to the problem? Sad to say, it is the latter. We are content with detecting them but it is really the cleaning and protection part that needs improvement.

Be Wary of Giving out Your Email Address

Written by Saran on May 25, 2011

Emails are supposed to make life easier but sometimes, it may be wise to choose who you give out your email to. Today, a lot of mischief can be done and normally this comes in forms of email attacks or email bombs. In such scenarios, don’t be surprised if you find your email downloading hundred to a thousand emails in one sitting. That is not the best part. You would be lucky if this was done only once since others would schedule it daily.

Why do they do it? One is for trials of these foolish software and the other can perhaps be for malicious reason. It is a fact that while many people on the web cannot be harmed physically, they can create headaches for you in the form of discomforts from the privileges you get from the web. One of the main elements an online user would need to use is his email and by doing these email attacks, it burdens the person on how to get important information usually sent through the web.

One cannot avoid such instances. But the best way to prevent it is to choose the people you give it too. For people you meet on the web, it would be wise to use free mail accounts from Gmail or Yahoo over your personal one. Avoid the troubles of such since it will not only be a discomfort, but a forgettable experience as well.

Online graphic design events

Written by dave on May 21, 2011

Graphic design contests refer to events which involve designing of print media design contents like logo, banner or flex, visiting card, illustration, brochures and so on. Normally, one can find hundreds of such contests online, though, it is recommended that one validates the originality and genuine nature of the event and the organizers.

Normally, graphic design contests are organized by upcoming ventures, in order to promote their brand, their product and/or their services to a vast population in one go. There are many others who are seeking potential ideas for their logo or other purposes. So instead of approaching multimedia service providers, it is the designers who approach the company. A company then announces prizes in form of cash, vouchers and accessories and so on. There are also some multimedia ventures who propose to recruit the winners into their own ventures.

It is recommended that one goes carefully through the stated terms & conditions of the contest. Some contests are restricted to a particular country, though they accept artworks from foreign candidates. Also, some contests are exclusively restricted to amateurs or fresher’s and prohibit the entry of industrial professionals. One must also keep a tab of the dates of submission of the artwork.

One should follow the codes given by the organizers like image resolution, image size, the color mode (RGB, CMYK, etc), the software which can be used for execution, the final output format, file size limits and so on. While sending the artwork, make sure you have named & organized the source files correctly.

Cheaper Isn’t Always Better

Written by Saran on May 16, 2011

cheaphostBlogs are the in-thing today and everybody on the planet wants to have one. WordPress being one of the most trusted and used platforms has suffered a great deal from the relentless attacks conducted by hackers who use it for spreading malware to the millions of users on the platform. Another weak link in the blogging trends are the millions of hosting companies, who all want to host as many people on earth they can so they earn as much profit as possible. These hosting servers and service providers might smell good on the outside but can be quite rotten on the outside so getting the right information on the hosting service you aim to use is vital for the survival of your blogging efforts. Web hosting review sites have sprung all over the place and are proving to be the best source of information for budding bloggers and SEO marketers. They offer unbiased information regarding the several or so hosting services giving you the tools to determine the best web hosting information around. These analytical tools may spell success or failure for your blog and thus SEO efforts, so don’t go out without them.

Of Unsecured WiFi

Written by Saran on May 9, 2011

wifiI didn’t realize that there are still a lot of people who do not really pay attention to securing their WiFi at home. I guess that I have always taken it for granted that once you set up any connection for home use, you install passwords and other measures to protect it. Apparently, in this day and age, not everyone has the same idea.

My colleague was telling me, just last week, that his connection at home seems to be running exceptionally slowly. First thing I asked him: are you using a wireless router? When he said yes, I asked him about a password. Just as I guessed, he said “What password?”

I moved to a new building a month or so ago and have been having problems having wired Internet hooked up. I have a mobile dongle which I can use to a certain extent but guess what? One day, I turned my WiFi on and voila, the laptop automatically connected to some fella’s wireless connection.

The fact is that this is such a common thing. Hotels, shops, and other establishments are also guilty of this neglect. I have a friend who works from home and is entirely dependent on the Internet. When her connection goes down, she simply gets in her car and drives to a nearby hotel where she can mooch.

It may seem funny or amusing, but if an unscrupulous individual gets wind of your unsecured WiFi, you just might get your bum bitten. If I were you, I’d make sure my WiFi is secure. How to do this? Let’s look at this in the next post.

Scheduling Change of Passwords

Written by Saran on April 27, 2011

If you are in charge of network security, one thing you may want to consider as far as laying down the law in safeguarding your network is the regular change of user passwords to avoid potential hackers and cracks based on how their passwords can be easily guessed.

For some users, it is easy to figure out their passwords. The normal passwords that people use include:

1. Birthdays
2. Anniversaries
3. Car Plate Numbers
4. Mobile Phone Numbers
5. Adding 123 to their names, or
6. Using “PASSWORD” as their password

Now there will be a lot of potential combinations depending on the length of the password. That is why the longer passwords (8 alphanumeric characters) are encouraged for users who access the network.

But while the probabilities of guessing or cracking passwords offer a lot possibilities, employing a regular maintenance as far as changing them is indeed something ideal to combat these hackers or malicious people from gaining access to the network and the programs in use.

Once cannot avoid the fact that some people’s curiosity and call for fame are the main reasons for wanting to be a hacker or code cracker. It is evident in people who are looking to try out their skill. They don’t think of the outcome which can cause a lot of problems.

So one good tip to avoid being hacked is to think like one. Once you do, think of security policies that can make it hard for you to breach a system. That is the best way to stay efficient in your line of duty in any organization.
