Intrusion Dention and Incident Response Course 2 page APA format with references Our text describes 5 actions an IPS is capable of performing (drop, log, block, reset, and allow). In a 2-3 page paper, using good APA formatting, briefly review each of the 5 actions. Next, create a hypothetical situation where each action (one situation for each action) is implemented. For each situation explain why the action is the correct choice for the situation. Purchase the answer to view it
Intrusion Detection and Incident Response (IDIR) is a critical component of an organization’s cybersecurity strategy. An Intrusion Prevention System (IPS) plays a vital role in IDIR by actively monitoring network traffic and taking actions to prevent or mitigate potential threats. This paper aims to provide a brief review of each of the five actions that an IPS is capable of performing, namely drop, log, block, reset, and allow. In addition, this paper will present a hypothetical situation for each action, explaining why it is the correct choice for that particular scenario.
The first action, drop, involves the IPS discarding the malicious network traffic before it reaches its intended destination. This action is suitable in situations where the incoming traffic is identified as a direct threat or an attack attempt. For example, suppose an organization’s IPS identifies an incoming packet that contains a specific exploit code targeting a known vulnerability in a critical system. In this case, the IPS would drop the packet, preventing the exploit from compromising the targeted system and potentially causing significant damage to the organization’s infrastructure.
The second action, log, focuses on capturing details of the detected threat or suspicious activity. When the IPS identifies such behavior, it logs relevant information, including the source IP address, destination IP address, timestamps, attack signatures, and any other relevant metadata. Logging is crucial for incident response and forensic investigations, as it provides valuable information for analyzing the attack and understanding the attacker’s motives and techniques. For instance, suppose an IPS detects multiple failed login attempts from a specific IP address to a critical server. By logging this activity, the organization gains valuable evidence that could help identify potential attackers and strengthen its defense mechanisms.
The third action, block, is employed when the IPS identifies traffic from a specific source or to a specific destination that is deemed problematic or malicious. This action involves blocking the identified traffic, preventing further communication between the source and destination. For instance, consider a scenario where an IPS detects a large volume of outgoing traffic from an internal host to a known command-and-control server associated with a botnet. By blocking this traffic, the organization effectively cuts off communication with the malicious server, preventing potential data exfiltration or further compromise.
The fourth action, reset, is used to disrupt suspicious or malicious connections by sending a reset packet to both the source and destination hosts. This action is particularly relevant in situations where the IPS detects an ongoing attack or unauthorized access attempt. For example, let’s say an IPS identifies an established connection from an external IP address to an internal host, and this connection exhibits signs of suspicious activity, such as abnormal data transfer or the use of known malicious protocols. By sending reset packets, the IPS terminates the connection and disrupts the attacker’s operations, minimizing the potential damage.
The fifth and final action, allow, is employed to permit selected traffic that has been identified as legitimate and safe. This action is typically used for specific situations where the IPS identifies traffic that, while initially flagged as suspicious, is subsequently determined to be harmless or necessary for legitimate operations. For instance, consider a scenario where an IPS initially blocks all incoming traffic from a specific country due to a high prevalence of malicious activity. However, the organization’s business requirements dictate that they establish a legitimate partnership with a company located in that country. In this case, the IPS can be configured to allow incoming traffic specifically from that partner company, thus facilitating the desired business relationship.
In conclusion, an IPS is capable of performing five main actions: drop, log, block, reset, and allow. Each action represents a distinct response to potential threats or suspicious activity. By employing these actions effectively, organizations can enhance their IDIR capabilities and safeguard their network infrastructure. The hypothetical situations discussed above demonstrate how each action can be applied in a specific context, highlighting the importance of making the correct choice to effectively mitigate potential risks and maintain a secure network environment.
