Elevated Privileges in Operating System Environments

ABC.

The three attacks that give a user elevated privileges to access resources that are otherwise blocked in an operating system environment are:

1. Backdoor: A backdoor is a hidden entry point or vulnerability in a system that allows unauthorized access by attackers. A backdoor can be created by attackers to bypass security controls and gain elevated privileges to access resources. Backdoors can be installed through various methods such as exploiting software vulnerabilities, social engineering, or physical access to a device.

2. Rootkit: A rootkit is a type of malware that is designed to hide its presence on a system and provide privileged access to an attacker. Rootkits can be installed through various methods such as exploiting software vulnerabilities, social engineering, or physical access to a device. Once installed, a rootkit can modify system files, processes, and settings to hide its presence and provide the attacker with elevated privileges.

3. Privilege Escalation: Privilege escalation is the process of obtaining elevated privileges on a system that are normally not available to a user. This can be achieved through exploiting vulnerabilities in software, misconfigured system settings, or social engineering. Once a user has elevated privileges, they can access resources that are otherwise blocked.

DoS (Denial of Service) and Smurf attacks do not provide users with elevated privileges to access resources. Denial of Service attacks aim to make a system or network unavailable to users, while Smurf attacks involve using a network of devices to overwhelm a target system with traffic. These attacks do not provide unauthorized access to resources.
