FOR in Python

FOR in Python Loops are used for sequential traversal, that’s mean used for repeating variables such as numbers, strings, lists or sets. The loop continues until it is terminated by the variable or by terminating the loop with the Break command. In this section, we want to learn how to use loops. loop in programming languages is an iterative method and is also found in other object-oriented languages. With a loop, we can execute a set of commands, once for each item. Loops in every programming language start with a set of rules, but they may be slightly different in…

What is the DHCP Server ? Include installation tutorial

What is DHCP (Dynamic Host Configuration Protocol): DHCP is a network management protocol on Windows servers to automate the process of assigning IP addresses and other network configuration settings to devices on a network. The DHCP server on a Windows server allows clients on the network to automatically obtain an IP address, subnet mask, default gateway, and DNS server information. This helps simplify network administration and eliminates network administrators to manually configure each device on the network. Some of the key roles and functions of DHCP on a Windows server include: IP address management: It automatically assigns IP addresses to…

Create VLan

What is a VLAN? Set of devices within the network that communicates with each other and forms a single local area network. In our concept, by dividing a larger network into smaller networks, each smaller network works like an independent network. The advantage of this method is reducing excessive network traffic and dividing it into smaller units. When two devices in the same network send data packets at the same time, the data collides and requires users to wait, we can prevent such collisions by dividing the network. There is also increased data security and logical partitioning in this method.…

What is Virtualization?

What is virtualization and what is the use of virtualization? It is a modern technology in the network and the use of this technology leads to cost and time reduction and increases efficiency and optimization. In this article, we examine the importance of Virtualization. With virtualization, we can create a layer between the hardware of computer systems and the software that runs on it. Of course, in this design, there is a logical view of consumption resources. The virtualization solution first gives you the ability to recognize a group of servers as a single source of computing to the operating…

Backup and Recovery

Backup and Recovery In this part we want to know, what is Backup and Recovery? Backup refers to storing information in external memory to protect information from accidents and loss. Recovery refers to returning data from a saved copy to the original location or to an alternate location where information has been lost or damaged. To store information, we use a separate system or media such as virtual hard drives, data storage servers or cloud storage space to protect them against the possibility of data damage. Why do we need backups? Why do we need backups? By making a backup…

Variables in Python

Variables in Programming Language Python The programing languages store data in the form of Variables. Every variable has data type, name, and a value assigned to it. Variables are assigned places in the computer memory to store data in which they can be known or unknown based on the value given to them. Also, they can be used for more than one value. They can tag and store data in memory and we can recall them when we need them. In this section, we want to introduce the most used Variables in Python. In Python, we have four commonly used groups…

What is the Server? And Types of Servers

What is a Server? In fact, we call a supercomputer or a computer with extremely performance as a server, so it is a computer or a program that can provides services to the programs installed on the user’s computer or another computer. It can refer to a physical machine, virtual machine, or software that performs services. We can use them for various purposes, we can change according to our needs. What Types we have? Servers can be divided into physical and virtual Physical: like a physical computer, but it works much more powerfully and is used to run server…

Python Standard Library

Python Standard Library With Python Standard Library, we call module code that is ready to use. We cannot use these modules without recall and if we need, we must call them. The Python standard library is very extensive and offers many features. In this library, we see internal modules that are often written in C language. For example, we can access the file input/output system through these modules, without these modules, Python programming will be inaccessible. These modules provide increased programming capabilities. In the installed version of Python in Windows or Mac, usually the entire standard library also install and…

Domain name servers or DNS contain a database that stores all public domains and…

MITRE ATT&CK

MITRE ATT&CK (Adversarial Tactics, Techniques, and Common Knowledge) is a framework developed by MITRE Corporation, a not-for-profit organization dedicated to solving problems for a safer world. ATT&CK is a knowledge base that categorizes the tactics, techniques, and procedures (TTPs) used by adversaries or attackers during cyber intrusions. The framework provides a comprehensive understanding of how cyber adversaries operate by organizing their behaviors into a matrix. This matrix consists of various tactics that represent high-level objectives an attacker may have (such as initial access, execution, persistence, privilege escalation, etc.) and techniques that represent specific methods or actions used to achieve those…
