Introduction
Security systems refer to the instruments, measures and methods employed by individuals, businesses, governments and other organizations to protect information, physical assets, property and people from potential threats. While security systems have typically addressed physical threats historically, with the rise of threats coming from cyber criminals, and increased reliance on networks, the need for security systems has been extended towards the digital realm. Security systems are used in any application where home, assets, property, and people need to be monitored and protected.
History
The first use of a security system was to simply protect property and assets around the home, such as locks on windows and doors. As technology and industry evolved, so did the need for more extensive and sophisticated security systems. With the invention of the telephone, security systems began to be commercially available, and often included burglar alarms and other measures to protect property and assets. In addition, closed-circuit television (CCTV) systems become popular for many businesses and organizations to monitor their premises and protect their property.
Modern Security Systems
Modern security systems have evolved significantly from their earlier counterparts. Now, security systems are no longer limited to simple locks and alarms, but can include digital monitoring, surveillance, and cloud-based access control. Digital security systems use advanced security protocols to protect information and monitor access to buildings and networks. Surveillance cameras, motion sensors, and access control systems can be used to monitor and protect physical buildings, while firewalls and antivirus software can be used to protect networks. Additionally, various authentication methods, such as biometrics and two-factor authentication, can be used to provide an extra layer of security.
Security System Architecture
A security system typically consists of the following parts:
1. Security Devices: Security devices are the physical components of the system and include cameras, motion sensors, access control systems, firewalls, and antivirus software.
2. Security Software: Security software is the software applications used to control and monitor the system. This can include authentication methods, digital monitoring and surveillance, as well as software systems used to manage access to buildings and networks.
3. Network: The network is the medium used to transmit information between security devices, with the network often controlled by routers and switches.
4. Security Policies & Practices: The security policies and practices are the rules and procedures in place not only to secure the physical and digital infrastructure, but also to ensure secure authentication and access control.
Conclusion
As the world becomes increasingly reliant on technology and networks, security systems have adapted to meet these needs. From the first locks and alarms used to protect physical property and assets, to modern security systems consisting of advanced security protocols, surveillance cameras, motion sensors, and access control systems, security systems have come a long way. Security systems are essential for protecting physical and digital assets, as well as ensuring people’s safety and privacy.
