In a sense, firewalls can be considered security guards in an airport. Intrusion detection systems IDSs detect and alert cybersecurity personnel to suspicious activities. These can refer to a set of sensors strategically placed within a network. They act as alarm systems that notify the cybersecurity team if something out of the ordinary occurs.
In an airport, IDSs can include the x-ray machines passengers pass through on their way in. These set off alarms when the person being screened is carrying a piece of metal. In an airport, an IPS can comprise automatic lockdown mechanisms that seal off an area in case of a breach.
Demilitarized zones DMZs are areas that are directly connected to firewalls. These do not contain valuable data. In an airport, shops, cafes, and restaurants can be considered DMZs. People are free to roam around in them, as they do not require authorization to access. As we said earlier, a combination of these elements makes up perimeter security.
All areas should be secured and protected against all kinds of threats. As for the type of connection, it can be analog or IP.
Currently, most installations are IP, although there are many occasions in which extensions have to be made in old installations, and both technologies must live together. When designing the installation, it is very important to consider getting effective real coverage , avoiding bad designs that generate dead zone in security cameras , such as the floor space that is just below the surveillance camera and that you can not see from this, the dead spaces produced by uneven terrain etc.
That space must be covered by another camera so that the unmonitored area is not created. That is why it is very important that an experienced company and trained engineers carry out this design.
Access control systems serve to restrict entry only to authorized personnel. By a pin, fingerprint or biometric pattern identification system , access to the perimeter of the plant is allowed, preventing the access of intruders. It also serves to delimit the spaces of the factory that can be accessed by staff and to dispense with keys. They are sensors that are established outside to detect movements through the use of infrared rays.
The system can be active, if it emits a power source to facilitate detection, or passive, if it is limited to sending an alarm when there is a change in temperature or a movement. It is used to detect presences by a fiber optic cable.
It is suitable to protect fences and walls , and to cover large perimeter extensions. It is a very useful perimeter security system.
They are radars that detect the presence of people or vehicles both at medium distance meters and short distance meters. They are suitable for use in isolated plants surrounded by fields and with open accesses that are difficult to control with another system. It can detect presences and movements totally hidden. Use microwave emission for this.
In this way they can provide full protection for your entire network perimeter, and maintain the same level of protection while your operation grows. This provides a reduction on the processing load on the appliance and helps ensure that threats never reach your network perimeter.
