In the context of investigating a security incident involving suspicious connections, a packet sniffer is the most appropriate tool for identifying the source IP of the offender. A packet sniffer captures and analyzes network traffic, allowing the analyst to see the details of each packet that is transmitted over the network. This includes source and destination IP addresses, port numbers, protocols used, and the content of the data being sent. By examining the captured data, the analyst can identify the source IP address of the suspicious connections and take appropriate action. This is particularly useful in scenarios where an attacker might be attempting to communicate with compromised systems within the network.

To prevent network availability issues related to peak memory pool buffer usage, the engineer should enable memory threshold notifications. This action allows the system to alert administrators before the memory usage reaches a critical level, enabling them to take proactive measures to prevent malfunction

 Upon receiving an alert of a zero-day vulnerability, the first step an engineer should take is to initiate a triage meeting to acknowledge the vulnerability and assess its potential impact2. This step is crucial for understanding the severity of the vulnerability, determining the scope of affected systems, and deciding on the subsequent actions to mitigate the risk. It involves gathering the relevant stakeholders and security experts to evaluate the threat and develop a response plan2.

One limitation of cyber security risk insurance is that it often does not cover the costs of damage done by third parties as a result of a cyber attack. This can include damages that result from the actions of partners, suppliers, or other external entities affected by the attack

Key risk indicators (KRIs) provide a clear perspective into the risk position of an organization. KRIs are metrics used to proactively measure risks that a business may face. They serve as early warning signs of upcoming crises, which can provide an organization’s management team time to create an action plan to mitigate that risk’s potential impact or prevent it from occurring2.

To assess the effectiveness of risk mitigation in an organization, it is essential to analyze key performance indicators (KPIs). These indicators provide measurable values that can demonstrate how effectively the company is achieving its key business objectives. In the context of risk mitigation, KPIs can include metrics such as the number of incidents or losses prevented, the percentageof risks mitigated, the cost savings achieved, or the level of stakeholder satisfaction. By analyzing these indicators, an organization can determine whether its risk mitigation strategies are successful in reducing the likelihood and impact of potential risks1.

Organizations often identify specific KPIs to track the effectiveness of their risk mitigation strategies1.

The process of risk mitigation involves implementing proactive measures to minimize the probability and impact of adverse events1.

Evaluating the effectiveness of risk mitigation strategies may involve performance metrics, data analysis, incident tracking, and feedback mechanisms

The type of attack described, where users are redirected to a malicious website instead of the intended company website, is known as Domain Name System (DNS) poisoning. This attack involves corrupting the DNS cache with incorrect information,leading users to fraudulent websites even when they enter the correct domain name. This can be used to collect sensitive personal data from unsuspecting users.

The error message “The Group Policy Client service failed to logon – Access is denied” suggests a problem with user permissions, which are managed by group policies in Windows environments. The unexpected modifications to system settings further indicate that an unauthorized user or process has gained higher-level permissions than originally assigned. This scenario is characteristic of an elevation of privileges breach, where an attacker gains elevated access to resources that are normally protected from an application or user. This can be achieved through various methods, including exploiting software vulnerabilities, configuration errors, or using social engineering techniques.

When there is a report of a possible malicious insider incident, the first action should be to inform the computer security incident response team (CSIRT) to investigate further. The CSIRT has the expertise and authority to conduct a thorough investigation, analyze the precursors and indicators, and determine whether an incident has occurred3.
