SYSTEMS LEVEL CONCEPTS

 A hypervisor is a software which is installed on top of the hardware, creating a virtualización layer and acting as a platform on which virtual machines (VMs) are created. Do not confuse the hypervisor with the operating system in question.

The hypervisor is responsible for extracting physical resources from hardware and converting them to virtual hardware. It is key to facilitating virtualization, creating what is known as the virtualization layer.

The same way as you must install the software to use the hardware, the hypervisor must be installed to allow virtualization.


Now that you know that virtualization hosts (hypervisors) provide hardware the ability to virtualize and therefore create multiple virtual machines running on the operating system (OS) of your choice whose function is partitioning.

The definition of partition in this context is the ability to execute multiple operating systems on a single physical system sharing the underlying hardware resources.

In a virtualized system, the hypervisor partitions, that is to say, It divides the hardware into several 'parts' to allow multiple OS running on a single machine.

eJPTv2 Review and Tips

 ¿What is eJPTv2? eJPTv2 is an ideal certification for all those who want to start as a pentester, stressing that it is a Junior certification, therefore it is unlikely to obtain any type of job only with said certification. You can get more information about eJPTv2 on their website(https://ine.com/learning/certifications/internal/elearnsecurity-junior-penetration-tester-v2). Information about the evaluation system Previously the evaluation criteria was based on passing 5 marks, including the final mark and 4 sections, on January 10, 2023 eLearnSecurity decided to change the evaluation criteria to the same one used in the previous version of eJPT(v1). To pass the exam and obtain your certification you must equal or exceed the minimum final grade (70%) The exam lasts a maximum of 48 hours. eJPTv2 preparation course The preparation course have a total of 143 hours and is divided into the following sections: -Assessment Methodologies -Host & Networking Auditing -Host ...

Understanding Nmap: A Powerful Network Exploration Tool in Kali Linux

- What is Nmap and how does it works? Nmap is a network exploration tool, and explains its basic functionality. Nmap uses various network protocols to scan and identify hosts and services on a network. - Understanding Nmap's different scan types and their purposes There are many different types of scans in Nmap, such as TCP, UDP, SYN, and others. - Tips for optimizing Nmap scans and avoiding detection You can optimize their Nmap scans for better results, such as adjusting timing options and using scan flags. Additionally, strategies to avoid detection by firewalls and intrusion detection systems (IDS) are covered. - Real-world examples of how Nmap can be used in network exploration and security assessments Nmap can be used in network exploration and security assessments - Nmap can be used in practical scenarios, such as identifying vulnerable systems, detecting open ports, and assessing network security. Nmap can be integrated with other tools, such as Metasploit and Ne...
