Common Networking Attacks Threats and Solution

Network attack is also known as threat or any other attack that cause the network to be unable to access information in the network. Some Network security threats have three primary flaws: technology weakness, configuration weakness and policy weakness.
An example of network attack is Reconnaissance attack. This is used to gather information on a specific network. This may look harmless but the information the hacker gathered might be used in other attacks like Denial of Service (DoS) attack. This cannot be prevented entirely. IDSs at the network and host level can inform an admin when this attack occur.
Another example is Packet Sniffer. This software application is use in a network adapter card in promiscuous mode, capturing all network packets. This attack can only be mitigated, by example authentication, switched infrastructure, anti-sniffer tools and cryptography.
Another example is Application Layer Attack. This attack exploit popular weakness (example protocols that are intrinsic to an application or system), uses ports that firewall allows, and can never be entirely eliminate. This attack can only be reduced by: analyzing operating system and network log files, keeping the OS and application with the latest and up-to-date patch,etc.
One more example is Unauthorized access. Which means people who are not authorized get access into the private network. There are many kinds of attacks that can cause this, like: password attacks. This can be mitigated by having a more complex password and taking away the ability of hackers to have access into the network.
