Nuclear Issues

Chernobyl, An Experiment Gone Wrong

On Saturday, April 26th, 1986 at 1:23 am, one of the reactors at the Chernobyl nuclear power plant exploded.
Ironically, the experiment consisted in testing how the power plant would respond in the event of an accident. The operators at the plant wanted to bring down the power output of the reactor to 25%, but over-confidence, poor training and poor knowledge of how a reactor works caused them to overdo it, and they ended up bringing down the power output to 1%. When they then tried to bring it up to 25%, the reactor overheated and exploded causing the worst nuclear accident in history.

Human Concerns: Home Computer Security
Posted on Saturday, March 17 @ 09:41:57 PDT by admin
Home Computer Security - Firewalls

What are some of the issues with security and protection of your personal data.


Home computer owners don’t realize that they need to pay attention to Computer security and protect their computers the same way they protect their investments, checking accounts or having insurance to drive their cars.

The internet has become a field where scam artists and all kinds of criminals hide under the protection of anonymity to lure unsuspected victims with creative plots and schemes to capture your personal information for illegal purposes. A wild west in its own right not getting any better.

Whether your computer runs MS Windows, Apple’s Mac, Linux or any other operating system, the issues are the same and will remain so as new versions of those systems are released.

There is a high possibility that your PC's Firewall security settings have not been properly configured even though the software is in most cases provided by the operating system and available in your computer.

Ignoring these tools settings, could expose your personal information and raise the probability that your computer may become exploited by hackers and/or malicious websites without your knowledge. This could also lead to attacks on your PC’s hard drive, be exposed to unwanted viruses, installation of malicious spyware and/or the running of unwanted script programs. Such scripts have been recently used by Russian hackers to surreptitiously install viruses on end-user's computers.

If your PC is not properly protected then these attacks could allow hackers to track your movements across the Internet. It also means that your information, ranging from passwords to credit card numbers, can be exposed and stored by sites that you visit. A successful hacker in other country and beyond the protection of our civil laws, could examine this information and extract it, setting the stage for identity theft, credit card fraud, redirect you to different websites without your consent or worse.

What Do I do to protect my PC?

The key is to be aware of these vulnerabilities, learn how these technologies work and understand the security problems you need to resolve. Not a trivial task recognizing the many aspects to consider and the many steps to follow.

We recommend the use of some type of network firewall whether software or hardware based to provide some degree of protection for your home PC. However, no firewall can detect or stop all attacks if you ignore all other additional security measures that must be implemented to provide a higher degree of security.

The only way to make a home computer 100% secure is to turn it off or disconnect from the internet. At a minimum, home computers need to have personal firewall, software patches up-to-date, password protection, antivirus and anti-spyware software installed and kept up-to-date to minimize, not eliminate the security exposure. Enhance Your PC Security by implementing today, practices and procedures that will help secure your precious data and prevent being taken for a tortuous ride.

Additional information for specific operating system firewalls can be obtained from the software providers of the operating system running in your PC.
