Physical Security is Protection of Assets from Strangers that may lead to Loss of Data

 


Protection of people, property, and physical assets from acts and occurrences that could cause damage or loss is known as physical security. Physical security is crucial, but it is often disregarded in favour of cybersecurity. It has actually expanded to become a $30 billion industry. If an attacker removes your storage media from the storage room, all the firewalls in the world won't be able to help you. Because physical security is getting more sophisticated thanks to technologies like artificial intelligence (AI) and the internet of things (IoT), IT and physical security are becoming increasingly intertwined, and security teams must collaborate to protect both physical and digital assets.

Physical security, at its most basic level, is about protecting your buildings, people, and assets from real-world dangers. Physical deterrent, detecting of intruders, and response to those dangers are all part of it. While it could be due to natural disasters, the word is mainly used to refer to preventing anyone — whether external actors or potential insider threats – from gaining access to locations or assets that they shouldn't. It might be keeping the general public out of your headquarters, on-site third parties out of sensitive work areas, or your employees out of mission-critical locations like the server room.

Limiting and controlling who has access to places, facilities, and materials is critical to maximising physical security measures. Access control refers to the steps taken to ensure that only authorised personnel have access to specified assets. ID badges, keypads, and security guards are common examples of business barriers. However, the technique, approach, and cost of overcoming these difficulties might all be very different. For most physical security systems, the structure is often the first line of defence. Fencing, gates, walls, and doors all serve as physical barriers against criminal access. Additional locks, barbed wire, visible security measures, and signs all help to limit the amount of haphazard cybercrime attempts.

Breaking into a secure data centre, getting into restricted portions of a facility, or using terminals they have no right to use are all examples of physical attacks. Attackers could steal or destroy essential IT assets such as servers or storage media, obtain access to critical terminals for mission-critical applications, steal data via USB, or infect your systems with malware. Extensive controls at the perimeter should be able to keep external threats out, while interior access controls should limit the chance of internal attackers (or at least flag unusual behavior).
