The threat environment that organizations face includes different types of attacks and different types of attackers who commit these attacks.

Select two types of network security attacks. Explain the two types of attacks, the types of attackers who are engaged in these attacks, and the counterattacks that are taken to mitigate the risks of these attacks.

Be sure to respond to at least two of your classmates’ posts.

• Please respond to student’s comment below:
• 1. A Denial of Service (DoS) attack is one in which the attacker tries to prevent the intended users from using a machine or network resource. Any system or network resource, including a website, an email server, or an online bank, can be the target of a DoS attack. Firewalls, intrusion detection systems, and rate restriction are frequently used as countermeasures to DoS attacks.

2. An assault known as a “Man-in-the-Middle” (MiTM) attack occurs when an attacker interjects himself or herself into a conversation between two people in order to listen in on the conversation or manipulate the messages being exchanged. Any form of communication, including email, instant messaging, and phone calls, is susceptible to MiTM assaults. Digital signatures, authentication, and encryption are often used defenses against MiTM attacks.
