What are the three critical security principles or goals of the CIA triad?
Answer(s): A
An engineer must discover alive hosts within the 192.168.1.0/24 range without triggering intrusive portscan alerts on the IDS device using Nmap. Which command accomplishes this goal?
Answer(s): B
The command nmap -sP (or the modern equivalent -sn) performs a ping scan that identifies live hosts without conducting any port scanning, preventing IDS port-scan alerts.
A vulnerability is discovered on a network. If successfully exploited, it will completely remove the ability of the system to limit disclosure of information to an unauthorized user. Which concept and value describes this vulnerability?
Answer(s): D
Which principle reduces the risk of attackers gaining access to sensitive data by compromising a low-level user account?
Answer(s): C
A developer is working on a project using a Linux tool that enables writing processes to obtain these required results:-If the process is unsuccessful, a negative value is returned.-If the process is successful, 0 value is returned to the child process, and the process ID is sent to the parent process.Which component results from this operation?
The described behavior is that of the fork() system call: on success it returns 0 to the child and the child's PID to the parent (negative on failure), resulting in a new process created by the parent.
What is the virtual address space for a Windows process?
The virtual address space is the range of virtual memory addresses available to a process; the OS maps those addresses to physical memory as needed via paging.
What is the difference between attack surface and vulnerability management?
The attack surface refers to all the possible entry points (e.g., open ports, services, exposed APIs, applications) through which an attacker could exploit a system. Attack surface reduction involves minimizing these entry points to reduce the risk of an attack. For example, blocking all unnecessary ports except essential ones (like port 80 for HTTP traffic) reduces the avenues an attacker can use.Vulnerability management is the process of identifying, assessing, and mitigating vulnerabilities (weaknesses or flaws) in a system, such as software bugs, configuration issues, or outdated systems. Correcting programming bugs, such as fixing buffer overflow vulnerabilities or patching software, is part of vulnerability management.
What is the difference between vulnerability and risk?
Vulnerability: A vulnerability is a weakness or flaw in a system, application, network, or process that could be exploited by a threat actor to compromise the security of that system. It represents a potential entry point or weakness that could be targeted by attackers. Examples include unpatched software, misconfigured settings, or design flaws that could be exploited.Risk: Risk refers to the possibility of harm or loss resulting from exploiting a vulnerability. It encompasses the potential impact or damage that could occur if a vulnerability is exploited by a threat actor. Risk considers the likelihood of an exploit occurring and the potential consequences or impact on an organization's assets, operations, or reputation.
