Network security is any activity designed to protect the usability and integrity of your network and data. The hubs and switches should be secured just like the servers. Physical security solutions + fire and safety solutions + Building asset management solutions In command and control centers with seamless integration and seamless scalabilities. Traditional methods of providing security in such networks are impractical for some emerging types of wireless networks due to the light computational abilities of some wireless devices [such as radio-frequency identification (RFID) tags, certain sensors, etc.] For example: a modern electricity power grid makes use of information technology and can connect through the network with other power grids, but this connectivity also opens doors for an unauthorized user, who has understanding of the system and its loopholes, gaining access to the power grid controls and blacking the entire city out. Most applications afford users with a privacy setting that allows them to choose what types of information and how much data are to be transferred or stored. Access control may start at the outer edge of your security perimeter, which you should establish early in … Physical security may sound like a no-brainer. Having an understanding of what you want to protect and designing a suitable approach for each level of data helps your organization to tackle any security issue that may arise. As technologies change, new strategies are developed to improve information technology efficiencies and network security controls. Networks and facilities dealing with highly sensitive intellectual property or other sensitive data probably need the strongest encryption available. Client computers should be physically secure as well. Network Security 6 Goals of Network Security As discussed in earlier sections, there exists large number of vulnerabilities in the network. There’s a big difference between a locked door and a door with a lock. Most of these devices undeniably include valuable organization information, which a disgruntled employee can exploit. Most computers come with anti-malware software and you can easily download a verified anti-virus application for your mobile phones. Safety measures for data security would involve implementing a set of controls, strategies, and applications that detect the comparative value of various datasets, regulatory compliance requirements, their intricacies, and then using applicable defenses to secure those resources.
