Wireless Security Tips

Posted by Geijutsu's Blog at 11:59 PM

Wireless Security: Encryption
Encryption is widely used for security of data, including wireless network security. Encryption is where data is translated into code for transmission via the radio waves. An encryption key, similar to a password, is needed to encrypt the code for transfer. If you are only minimally concerned with security, such as in wireless home network security, you may consider WEP encryption, which some find easier to configure with their current equipment.

Wireless Security: Protecting your password 
Your passwords are crucial to your wireless network security and should not be revealed to unauthorized individuals. Do not leave your password lying around or written in an obvious location. When entering your username and/or password, make sure people are not milling around and looking over your shoulder. Be very careful of responding to emails asking for passwords. Most legitimate companies do not ask for passwords via email due to the lack of security. These tips are useful for both wireless security and wired security.

Protect your business from online threats with the best internet security software. Wireless network security is important. Always make sure to require a password from users connecting to your computer. Be careful about what folders you allow others to have access to. You can also set passwords on specific folders to further increase security.

Sleep Deprivation May Encourage Risky Decisions

Posted by Geijutsu's Blog at 11:46 PM

Sleep deprivation may lead to overly optimistic thinking that fails to properly consider the potential consequences of financial risks, a new study suggests.

Duke University researchers assessed the effects of sleep deprivation on 29 adult volunteers who were asked to take part in several economic decision-making tasks in the morning after a normal night of sleep and again one morning after a night of sleep deprivation.

Using functional MRI scans to study brain activity, they found that those suffering from lack of sleep had increased activity in regions that assess positive outcomes and decreased activity in regions that process negative outcomes.

Nuclear Radiation Effect

Posted by Geijutsu's Blog at 6:44 AM

Basic Effect of Nuclear Weapons
Nuclear explosions produce both immediate and delayed destructive effects. Blast, thermal radiation, prompt ionizing radiation are produced and cause significant destruction within seconds or minutes of a nuclear detonation. The delayed effects, such as radioactive fallout and other possible environmental effects, inflict damage over an extended period ranging from hours to years.

Blast Effects
Most damage comes from the explosive blast. The shock wave of air radiates outward, producing sudden changes in air pressure that can crush objects, and high winds that can knock objects down. In general, large buildings are destroyed by the change in air pressure, while people and objects such as trees and utility poles are destroyed by the wind.
