There are different types of network threats that can cause harm or damage to your computer. A network threat is defined as a security incidence that analyses and gains information from your network infrastructure which can cause it to eventually become corrupt. In a lot of situations, the network threat may not only exploit the software applications, but can equally attempt to gain unauthorized entry into your network devices. Network devices that are not monitored are the major areas where information can leak in an organization. In several organizations, all transmittable files, all user logon, all web page requests, all email address are monitored by a network device. And in some instances, voice messaging and telephone services are monitored by a network device. When the network attack is successful at owning your network device, then the entire network will be at their mercy. There are several types of network threats as they cut across different platform types and software. The following are some of the most common types that can cause considerable damage to the computer.
This is another form of network threat attacks where the attacker uses deception or perception to assess the network. The attackers generally make use of the email or the telephone to perform their malicious act. They use all source of trick to get the host’s attention to give in to thei demands.
These are the types of network threats that try to gather information about the services offered by their attacking hosts, the type of network device they use, and the types of IP addresses that visit the network. These information, when gathered, help the attacker avoid being spidered when they eventually attack the network.
Sniffing is a network threat that intercepts data packets that traverse through a network. These types of network threats are found at the Ethernet base in conjunction with the network interface card to sniff into all data from the host network to the user network and vice versa.
These are the most common types of network threats around today. They resemble useful software but essentially perform malicious or unintended actions when they are finally launched. Most of them are in form of remote controlled spyware.
All devices that are connected to the internet will always send IP data grams into the network. Such packages also convey the IP address of the sender and the application layer data. Spoofing is one of the types of network threats that can attach a network protocol and arbitrarily replace its IP address with the attacker’s own. This is referred to as IP spoofing. With this type of threat it is very difficult to locate the main source of the sent datagram.
But there is a way to tackle these types of network threats. Routers can be employed to do what is called ingress filtering. They detect this attack by checking all the addresses of the incoming datagrams and find out whether they are from genuine sources. When the sources can be reached through their own interface, them it means the incoming addresses are genuine, but if they are not reachable the router discards such address and prevent such addresses from getting access to the network.
