What are some common security events of interest?

The correct answer is that all of the listed options represent common security events of interest. Each of these events plays a significant role in the landscape of cybersecurity and can indicate potential threats or vulnerabilities in a system.

Malicious code refers to harmful software designed to damage, disrupt, or gain unauthorized access to computer systems. This can include viruses, worms, and trojan horses. Monitoring for malicious code is crucial, as its presence can compromise the integrity and confidentiality of sensitive information.

Denial of Service (DoS) attacks involve overwhelming a target system, such as a server, with a flood of traffic, rendering it unable to respond to legitimate requests. This type of attack can severely disrupt operations, leading to significant downtime and loss of services. Understanding and tracking DoS attacks are vital for maintaining system availability.

System updates, although often seen as routine maintenance, can also be significant security events. They are essential in closing vulnerabilities that could be exploited by attackers. Neglecting to apply updates can leave systems exposed to threats, making it important to monitor and manage update processes effectively.

Collectively, these events highlight the diverse threats facing computer systems and underscore the importance of vigilance in security monitoring. By acknowledging that all of these factors are events of interest, organizations can
