Physical Threats Threats can come from many sources and can affect different parts of a system and network. There are physical threats that can compromise a system and deny the use of network resources. Damage can occur on any piece of hardware connected to the system such as servers, routers, switches, and workstations/ PC’s. Access should be controlled to the location where vital hardware is stored. Ensure all doors remain locked and only authorized individuals enter restricted areas. There can also be damage caused by electrical threats. A voltage spike or total power loss can shut down critical systems and cause negative impacts throughout the company.

A network administrator can also allow only specified MAC addresses onto the network. Internal threats can happen to any organization especially those with many employees. An internal threat can come from a current employee or vendor and usually they are disgruntled in some way. Preventative measures are similar to those for internet threats including spyware, anti-virus software, firewalls, and intrusion detection/prevention systems. External threats can occur virtually or in-house, depending on the skill level of the attacker and their ultimate goal. The attacks occur outside the company or organization.
LAN, WAN, Wireless A local area network (LAN) is a small grouping of computers and devices that are connected through various topologies in a small geographical area. A LAN is usually within one office building, or several connected buildings like a school campus. The topology for a LAN can be a bus, ring, or star depending on the individual network. The most common seems to be the bus topology. Kudler Fine Foods uses an Ethernet bus topology at each store and will use the same set-up at each of the new stores. A wide-area network (WAN) can be several systems or devices connected over a large distance using phone lines and radio waves. Alternatively, a company can have separate LAN’s around the country or world that are interconnected using leased communication lines. These connected LAN’s can span country and international borders. Kudler
4)LAN (Local Area Network)-A LAN is a group of computers or devices connected together through a local network.LAN connections are usually very inexpensive.They are also usually very fast.LAN connections are usually within the same building.
It is a "network of networks" that consists of millions of smaller domestic, academic, business, and government networks, which together carry various information and services, such as electronic mail, online chat, file transfer, and the interlinked web pages and other resources of the World Wide Web (WWW).
A: LAN: LAN stands for Local Area Network. LAN is a network which cover a small area like colleges, schools or buildings.
In this modern day and age of computing, networks are a huge part of IT. It is important now more than ever that data sent over any network, whether it be a LAN (Local Area Network) or WAN (Wide Area Network; The Internet) is kept safe, private (when required) and uninterrupted in
A LAN is a ‘Local Area Network’. It is a small network of computers most often
Routers and switches will be utilized to route network signals to all areas of this large network. Telephony systems will be introduced to serve the VOIP located at each location to assist with communication needs. Wireless technologies will also be needed to assist with mobility and other devices such as printers, laptops, fax machines, etc. Lastly, a physical firewall will be enforced at each location to protect the network from internal and external intruders.
When setting up a LAN the architecture that you decide to choose is important. There are several factors that are decided when choosing said architecture, some of these being network speeds, types of cables, and access control mechanisms like collision detection (Team, 2011). The most common on in today’s LANs is Ethernet. These can be either wireless, wired, or a hybrid of both.
It is generally limited to a geographic area such as a writing lab, school, or building. Rarely are LAN computers more than a mile apart. In a typical LAN configuration, one computer is designated as the file server. It stores all of the software that controls the network, as well as the software that can be shared by the computers attached to the network. Computers connected to the file server are called workstations. The workstations can be less powerful than the file server, and they may have additional software on their hard drives. On many LANs, cables are used to connect the network interface cards in each computer; other LANs may be wireless.
LAN- sub network that is made up of a group of clients plus servers which are under the control of one central security.
LANs, WANs and on the internet, and provide data storage independent of the location. ! !
Network security has changed significantly over the past years. There is more and more data to monitor and analyze in order to detect the activity of your data and systems. Securing a network has many variables. Password authentication, network access, patches, anti-virus protection, intrusion detection, firewall and network monitoring tools are just a few of the things you can do to protect yourself.
A LAN is a network of computers in a specific area interconnect using a variety of network media. For example, WBHS LAN are all the computers connected to the WBHS network via Ethernet, Wi-fi or other. This is different from a WAN (Wide area network) which extends to a much wider area such as a town, city and country. LAN are usually more restricted in access and more numerous.
According to the U.S. Department of Homeland Security in the article Cyber Threats to Mobile Phones, phones are now sharing hardware and software similar to a PC and becoming each time more like a PC. Therefore, the risks of being hacked are increasing, allowing hackers to attack mobile devices the same way as if they were doing it with a regular PC. Personal and professional information are more often stored on mobile devices therefore it is imperative to have our data secure. Security solutions for mobile devices are not as broad or high-tech as those for PCs. The majority of mobile security relies on the proper use and smart choices that the user makes on a daily basis to be protected against cyber attacks. Even the most careful person can be attacked but the possibilities of that happening are less when you are proactive.
Local area networks (LANs). DEFINITION The concept of local area networks (LANs) is not new. It represents a logical development of computer technology. With the advent of microcomputers in the 1980s many office workers began bringing their own disks into work, compromising data integrity.
The Merriam-Webster’s Dictionary defines cyber security measures taken to protect a computer or computer system (as on the Internet) against unauthorized access or attack Most people think that hackers are just people that want to mess up your computer, but real hackers break into systems because they want to see what they can do, then they might leave a message on the victims computer, but that’s it. So, the computer security people protect from those other hackers that want to mess up peoples computers. The means we take can as individual to protect ourselves in the cyber world is be anyomous on websites, don’t post your personal information ,have virus protection install on your computer, get spy
