This may involve creating backdoors, planting rootkits, and deploying other types of malware that allow the attacker to maintain a connection and retain control over the target environment, even after the initially exploited vulnerability has been patched. Additionally, the attacker may perform various actions to avoid detection, such as disabling security tools, clearing logs, or using covert communication channels. The primary goal of maintaining access is to facilitate ongoing access and reconnaissance, enabling the attacker to gather more information, carry out further attacks, and obtain maximum control over the target environment.
Guide for Maintaining Access in Penetration Testing with CompTIA Security+
Maintaining Access: Maintaining access refers to the methods and techniques that a penetration tester, often known as ethical hacker, uses to stay in the system after initially penetrating it. The main goal is to ensure continuous availability of resources and data, even after the testing process is completed.
Why it's Important: Maintaining access is important because it prevents unauthorized users from compromising the security of system assets. This method allows testers to understand how an attacker could remain in the system undetected and provide countermeasures to prevent this.
How it Works: A successful penetration test will typically exploit a vulnerability in a system to acquire access then install a backdoor, which allows ongoing access to the tester. The tester can then identify any security flaws from the inside, and these can be addressed by the owner of the system for greater security.
Exam Tips: Answering Questions on Maintaining Access: When answering exam questions on maintaining access, emphasize your understanding of the process' importance to system security. Ensure you understand key aspects such as backdoors, rootkits, and the use of these for prolonged access. Discuss the ways in which these tools can be identified and removed, to demonstrate your knowledge of countermeasures. Be prepared to describe real-world examples of maintaining access to show a concrete understanding of the concept.
