Logical and Physical Security - What are the main differences

Logical security software protects your computer by discouraging excessive user IDs and user implementation, passwords, authentication, biometrics and smart cards. Physical security prevents and deters intruders from entering a building, installation of fences, alarms, cameras, security guards and dogs, electronic access control, intrusion detection and access control administration. The difference between logical security and physical security is the logical security to protect access to computer systems and physical security to protect the site and all that lies within the site.

The time is a serious threat to physical safety, because natural disasters can happen at any point of time. When planning a site selection should consider the location of the site and what weather events of the past and present successful position. If a position is subject to natural disasters you should weigh the consequences of the threat against the safety of personnel, structure, building computers and data. If the consequences compromise the security of the whole company then a more stable position should be chosen to accommodate the site. Moreover, the threats of the time can come in many forms including fires, floods, tornadoes, earthquakes, hurricanes, humidity, cold, damage from pests, snow and ice.

In recent years, the safety logic has become the first line of security experts. Logical security may consist of hardware and software firewall anti-virus, anti-spyware, anti-phishing applications, as well as other security applications. This type of security can also be enhanced through the upgrade of operating systems and protocols that may have been exposed to hackers, basically, any measure that prevents intrusions through the applications or data sources.

However, physical security can also be detrimental to the overall health of a system capable of malfunctioning hardware that also supports logical systems more secure. Physical security in general applies to weather, fire / chemical, construction, structural failure, energy issues, biological threats, and threats posed by trafficking in the local physical network. Methods for securing a network includes physical education staff, administrative controls, physical controls, engineering controls, environmental and life / safety controls. Control who has access to physical premises may be essential, which is aided by security personnel, badges, access channels and key policies visitors. Choosing the right site can help to prevent, if not cut off the possibility of environmental disaster or structural collapse. Technical controls can consist of smart cards, access logs, intrusion detection and access control biometric .......
