physical security for networks

Physical Layer Security for Next Generation Wireless Networks: Theories, Technologies, and Challenges Abstract: Physical layer security (PHY-security) takes the advantages of channel randomness nature of transmission media to achieve communication confidentiality and authentication. (Just kidding.). 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. While it is good to backup your data, you still want to ensure you’re the only one who can access the backup or at least someone you authorize. Thus, during transmission, data is highly vulnerable to attacks. between a video surveillance system and a swipe card-based access control/user permissions system, have been around for quite a while. (A common hacking technique is to boot the server from a floppy, thus bypassing the carefully crafted security features of the network operating system. The first level of security in any computer network is physical security. Network Security 6 Goals of Network Security As discussed in earlier sections, there exists large number of vulnerabilities in the network. This ensures that even when your gadgets end up in the hands of a malicious attacker, at least they can’t access your sensitive information. While it’s incredibly important to protect your business from digital attacks, you also need to think about the physical security of your network. CIP 014 sets out certain requirements that the utilities must carry out to meet physical security standards (beyond defense-in-depth). Experts say that encrypting network data and physical security data that travels on the network fixes the physical security problems. Physical security is important for workstations but vital for servers. Physical security describes security measures that are designed to deny unauthorized access to facilities, equipment and resources and to protect personnel and property from damage or harm (such as espionage, theft, or terrorist attacks). You should instruct users to not leave their computers unattended while they’re logged on. In IoT, the physical layer security has recently become an emerging technique to further improve the security of IoT systems. Don’t just stack them up next to the server. Your trash can contain all sorts of useful information: sales reports, security logs, printed copies of the company’s security policy, even handwritten passwords. The hubs and switches should be secured just like the servers. The possibilities of one of your physical assets being stolen are increasingly high, and stolen mobile devices present an even greater threat. Physical security is the protection of personnel, hardware, software, networks and data from physical actions and events that could cause serious loss or damage to an enterprise, agency or institution. 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.] A deliberate act of espionage could include a competitor entering into an organization with a camera or a disgruntled employee physically stealing sensitive data for malicious intent. Virtual segmentation uses the same design principles as physical segmentation but requires no additional hardware. Even if your gadget is stolen or lost, you don’t have to lose valuable data. Not only does that make them easy to steal, it also defeats one of the main purposes of backing up your data in the first place: securing your server from physical threats, such as fires. 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. Access control may start at the outer edge of your security perimeter, which you should establish early in … 9 Rules to Help You Build Your Threat Intelligence Program, mobile devices present an even greater threat, Design policy to survive a potential data breach, Todd Anderson, Sr. This includes protection from fire, flood, natural disasters, burglary, theft, vandalism and terrorism. It could also include software attacks, acts of theft, vandalism, sabotage, information extortion, and compromise of intellectual property. To protect the server, follow these guidelines: Mount the servers on cases or racks that have locks. Physical security describes measures designed to ensure the physical protection of IT assets like facilities, equipment, personnel, resources and other properties from damage and unauthorized physical access. Client computers should be physically secure as well. Sadly, only a few smartphone users lock their phones with a PIN or pattern.

Physical security has been a central feature of the Quality Network for Forensic Mental Health Services’ standards since they were first published for medium secure services in 2007. For many systems, basic encryption may suffice. This is a good beginning assumption for this section. 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. Physical security refers to the protection of building sites and equipment (and all information and software contained therein) from theft, vandalism, natural disaster, manmade catastrophes, and accidental damage (e.g., from electrical surges, extreme temperatures, and spilled coffee). In high-traffic areas (such as the receptionist’s desk), users should secure their computers with the keylock. As simple as this sounds, locking your phone with a password will slow down the attacker from accessing your device. You need to take certain steps to protect valuable information from attackers, including: Organizations need to adopt comprehensive security to prevent and mitigate unauthorized access to sensitive data.

Taking proactive measures to ensure both digital and physical security can go a long way in protecting your data and mitigating potential attacks. Security is a very important issue in the design and use of wireless networks. An attacker can target the communication channel, obtain the data, and read the same or re-insert a false message to achieve his nefarious aims. While most cybersecurity solutions concentrate on anti-malware tools, firewall configurations, and other data security measures, however, physical security of IT resources is just as important. Another physical security strategy ignored for mobile devices is the need to backup sensitive information. Networks and facilities dealing with highly sensitive intellectual property or other sensitive data probably need the strongest encryption available. How do you know that the person who vacuums your office every night doesn’t really work for your chief competitor or doesn’t consider computer hacking to be a sideline hobby?
