Question: The latest challenge in strategic security has been aerial drone attacks. Explain the threats posed by use of drones. Suggest measures to protect against drone attacks.
Answer: Drones have gained immense popularity among defence forces as well as rogue elements as a potential replacement for humans in carrying out attacks. These drones can be operated remotely and precisely for greater impact.
Threats posed by drones
- Hardly detectable
Unlike human terrorists and missiles, drones are not easily detectable. They can move without getting recorded on Radars and are difficult to sight through plain eyes.
- Superior reach
Human reach is restricted to certain areas in a defence establishment. Drones can move in and out of a secure zone with less chances of getting caught.
- No human casualty
Drones can fail sometimes due to technical or climatic reasons. But they do not have human casualties. If they get caught, it will be difficult to get information out of them.
Measures to protect against drone attacks
- Anti-drone system
There are many anti-drone systems that have come into play after increasing use of drones for terrorism. These systems can identify and also intercept drones to eliminate them.
- Radio and optical jammers
Drones need optical and radio signals for control. If these signals are stopped from reaching these devices, they fail to operate and video feed will be cut.
- Laser walls
Non-visible laser walls can be set up around high secure areas. This will act as an alarm if any object comes into contact.
Thus, security systems are evolving to provide protection against the latest threats, including
drones. There should be specific policies on owning, operating and selling drones.
