A captive portal is a web page that a user is prompted with when connecting to a public access WiFi network. The captive portal states the terms, agreements, and acceptable usage policy for the user and then permits usage of the guest network upon the user’s acceptance of the policies. There are a handful of benefits that come with using a captive portal, including the ability to separate network traffic, limit data usage, collect valuable data, marketing and business recognition, and liability protection. With all of these benefits, there is very little reason to not have a captive portal as the gateway to your guest network.
What is subnetting, what is it used for, and why is it important?
Subnetting is the practice of dividing up a network into two or more networks. Common advantages of subnetting include enhancing routing efficiency, network management control, and improving network security. While these are just a few of the benefits that subnetting provides, they are the most noticeable after immediately implementing a subnet system.
WiFi Alliance is a non-profit organization that promotes WiFi technology and certifies WiFi products for conformity to certain standards of interoperability. While the WiFi Alliance owns the WiFi trademark, manufacturers may use the trademark to brand certified products that have been tested for interoperability.
While there are many types of cable, there are three main types, or categories, of Ethernet cable that are commonly used for network deployments: Cat5e, Cat6, and Cat6a. Each of these cables are constructed of fundamentally similar twisted pairings of copper cables, and are each used with the same RJ-45 connection to plug into computers, routers, switches, or other network equipment. There are reasons for and against the use of all three, such as cost, ease of installation, and performance.
There are wires in wireless networks? Yes, and probably more than you think. For an office’s wireless setup, there are wires and cables that need to be run throughout the entire office. In this post, we will be talking about the basics that are required in order to prepare and execute the pathways and cabling in an office setting.
Where and how an access point (AP) is hung is a simple process that requires planning and logical decision making based on a handful of factors, including the surface material, the mounting type of the access point, and the neighboring entities. Using a combination of proper mounting equipment and precise placement allows for an access point to perform to the best of its ability.
An intrusion detection system (IDS) monitors network devices in order to grant security administrators the ability to identify attacks in progress and take appropriate action to protect a network. In order for users on a network to access a web server on the internet, the firewall must allow traffic through port 80. However, this open port is often used as an attack vector for hackers and malware to gain access to your network. An IDS examines this traffic and compares it with known exploits; similar to how antivirus software uses known virus signatures to identify threats. When the intrusion system detects a match to a known exploit, it sends an alert to the security or web server administrator so they can take action. Intrusion prevention systems (IPS) are very similar to IDSs, but as opposed to just sending an alert, these systems go one step further and automatically take action to prevent an intrusion.
“If it is online, it can be hacked!” This phrase has served as the motivation for both hackers and security professionals for years. Every network has its weaknesses and vulnerabilities that hackers can exploit to gain access to your network. The only way to completely avoid a potential attacker is to pull the network cable. However, depending on the circumstances, doing this could actually create the exact denial of service result the attacker intended.
It is important to understand that a wireless network isn’t wireless at all. There are cables, access points, and various other pieces of hardware that need to be installed when implementing a wireless network. With any installation, there are specific tools that are required to get the job done. While a WiFi project might require some specific tools depending on the building’s materials, size, and network needs, we have compiled a list of the basic tools and materials needed for a WiFi installation kit.
A personal WiFi router is generally used for residential purposes. They are directly connected to a modem that is provided to you by your Internet Service Provider (ISP) and are capable of propagating wireless signal throughout a home.
