Physical Security Measures ISSL5112 1. Cable shielding •Cable shielding is a method used to prevent EMI interference otherwise known as Electromagnetic Interference from corrupting the data being transported through the cables. •Cable shielding is done by enclosing the cable with a common conductive layer to prevent intrusion through the cables. •An example of this is a four-conductor shielded cable. •These cables are mainly used in security systems. 2. Corner bolt •Corner bolts are used to secure an object such as a computer or desktop to prevent theft in an organisation. •These corner bolts are mainly used in most business organisations to prevent theft. •Corner bolts such as this one illustrated in the picture can prevent theft from occurring. 3. Electronic trackers •Electronic trackers are devices used to track activity on a certain object such as if a computer was removed from its area. •Electronic trackers can be devices such as GPS to track the location of an object. •These devices can be used in most organisations to track the equipment such as computers if they are removed from their specified area and alert the organisation. 4. Identification badges •Identification badges, otherwise known as ID’s are used as a form of identification in a organisation to show that you are a part of the organisation. •These identification badges are used in organisations as well as retail stores such as Dis-Chem to show who works there. 5. Proximity-release door openers •Proximity-release door openers are used for secure access into an organisation and restricted areas in the organisation. •These mainly require some sort of identification badge with a small radio transmitter placed in it. •These are given to the authorised employee’s. •Mainly given for access to the computer room for secure access. 6. Room shielding •Room shielding is a process in which a nonconductive material is sprayed on the walls of a computer room to decrease the amount of signals transmitted into the room. •This is mainly used to create secure areas for the computer room. •Mainly used in organisations to prevent data loss or hacking. 7. Steel encasements •Steel encasements are used to secure a computer or an object to an area which is locked to prevent theft. •Mainly used in organisations which give public access to the computers. •Such as schools or internet cafes.
