What is a function of the application hardening process'?
Application hardening is the process of configuring an application to reduce its attack surface and make it more secure. The process involves several steps, including removing unnecessary features or services, enabling security features, configuring access controls, and implementing secure coding practices. By disabling unnecessary features or services, the application becomes less vulnerable to attacks that exploit these features or services. For example, an application that does not need to run as a privileged user should be configured to run with limited privileges. Additionally, disabling or removing unused or unnecessary application files and programs can help reduce the attack surface. This makes it harder for attackers to exploit vulnerabilities in the application. Penetration testing and patch management are also important components of application hardening, but they are not the primary function of the process. Reference: Section 4.2 Security Hardening and Monitoring, page 228.
Which statement is true regarding virtual provisioning?
Virtual provisioning is a storage management technique that enables more efficient allocation of storage to compute systems. It allows storage administrators to create virtual storage resources that are presented to compute systems as if they were physical resources, even if the physical storage capacity does not exist. Virtual provisioning supports various types of virtual storage, including thin LUNs and thin clones. Thin LUNs enable shared and rapid expansion with only minor disruptions. Multiple shared storage pools can be created, and each pool can be allocated to multiple thin LUNs. However, virtual provisioning does not prevent issues that arise from oversubscription; it is important to monitor and manage capacity utilization to avoid performance degradation or service disruptions. Reference: Section 2.5.1 Virtual Provisioning, page 107.
