White Hat Hackers

White hat hackers choose to use their powers for good rather than evil. Also known as “ethical hackers,” white hat hackers can sometimes be paid employees or contractors working for companies as security specialists that attempt to find security holes via hacking.White hat hackers employ the same methods of hacking as black hats, with one exception- they do it with permission from the owner of the system first, which makes the process completely legal. White hat hackers perform penetration testing, test in-place security systems and perform vulnerability assessments for companies. There are even courses, training, conferences and certifications for ethical hacking.

Network Topology

Types of Network Topology Network Topology is the schematic description of a network arrangement, connecting various nodes(sender and receiver) through lines of connection. BUS Topology Bus topology is a network type in which every computer and network device is connected to single cable. When it has exactly two endpoints, then it is called  Linear Bus topology . Features of Bus Topology It transmits data only in one direction. Every device is connected to a single cable Advantages of Bus Topology It is cost effective. Cable required is least compared to other network topology. Used in small networks. It is easy to understand. Easy to expand joining two cables together. Disadvantages of Bus Topology Cables fails then whole network fails. If network traffic is heavy or nodes are more the performance of the network decreases. Cable has a limited length. It is slower than the ring topology. RING Topology It is called ring topology because it ...

Grey Hat Hackers

Grey Hat Hackers As in life, there are grey areas that are neither black nor white. Grey hat hackers are a blend of both black hat and white hat activities. Often, grey hat hackers will look for  vulnerabilities  in a system without the owner’s permission or knowledge. If issues are found, they will report them to the owner, sometimes requesting a small fee to fix the issue. If the owner does not respond or comply, then sometimes the hackers will post the newly found exploit online for the world to see. These types of hackers are not inherently malicious with their intentions; they’re just looking to get something out of their discoveries for themselves. Usually, grey hat hackers will not exploit the found vulnerabilities. However, this type of hacking is still considered illegal because the hacker did not receive permission from the owner prior to attempting to attack the system. Although the word hacker tends to evoke negative connotations when referred to, it is i...

What is a Network?

What is a Network? A network consists of two or more computers that are linked in order to share resources (such as printers and CDs), exchange files, or allow electronic communications. The computers on a network may be linked through cables, telephone lines, radio waves, satellites, or infrared light beams. Two very common types of networks include: Local Area Network (LAN) Wide Area Network (WAN) You may also see references to a Metropolitan Area Networks (MAN), a Wireless LAN (WLAN), or a Wireless WAN (WWAN). Local Area Network A Local Area Network (LAN) is a network that is confined to a relatively small area. It is generally limited to a geographic area such as a writing lab, school, or building. Computers connected to a network are broadly categorized as servers or workstations. Servers are generally not used by humans directly, but rather run continuously to provide "services" to the other computers (and their human users) on the network. Services...
