It is usually not difficult to determine if a DoS attack is underway. A large number of complaints of inaccessible resources is the first indication of a DoS attack. To minimize the number of attacksminimize the number of attacks, a network utilization software package should always be run, and this should also be required in the network security policy. A network utilization graph showing abnormal activity is an indication of a possible DoS attack.A DoS attack may be a component of a larger attack event. DoS attacks can cause problems on the network segment where the attacked computers are located. For example, the packet per second capacity of a router between the Internet and a local area network may be exceeded as a result of the attack, affecting not only the target system but the entire network. If the attack is carried out on a large enough scale, the connectivity of the Internet can be affected throughout a geographic area.Not all service unavailability is the result of a DoS attack, and some service unavailability is the result of malicious activity. In any case, DoS attacks are among the most dangerous types of attacks, and it is critical that cybersecurity practitioners act quickly to mitigate the impact of such attacks.1.3.4 Mitigating Network Attacks1.3.4.1 Mitigating Cyber AttacksA wide variety of cyber attacks, cyber attack methodologies and cyber attack classifications exist. How can we mitigate these cyber attacks? The type of attack (as indicated by the detection, access, or DoS attack classification) determines the means employed to mitigate the cyber threat.
