Pre-authentication Remote Code Execution (Pre-auth RCE) is a critical security vulnerability that allows attackers to execute arbitrary code on a remote system without needing to authenticate. This means that anyone with access to the vulnerable system, often exposed online, can exploit this flaw and potentially gain unauthorized control. What is RCE? Remote Code Execution (RCE) Read More …

CRC – Cyclic Redundancy Check
Cyclic Redundancy Check (CRC) is a widely used error-detecting code that helps ensure the integrity of data during transmission or storage. It is a crucial concept in networking and data communication, making it essential for new IT students to understand how it works and its applications. What is CRC? CRC is a method used to Read More …
smbclient test for 445
While smbclient is primarily used for interacting with SMB shares (like listing shares or accessing files),, it can implicitly indicate if port 445 is open and accessible. If smbclient can successfully connect to an SMB share on a target system, it means port 445 is open on that system and allowing connections. How it works: When you use smbclient Read More …
FCS – Frame Check Sequence
A Frame Check Sequence (FCS) is an essential component in data communication protocols, serving as a method for error detection. It is a sequence of bits added to the end of a data frame, which allows the receiving device to verify the integrity of the data it has received. Understanding FCS is crucial for new Read More …

LCP – Link Control Protocol
The Link Control Protocol (LCP) is a critical component of the Point-to-Point Protocol (PPP), which is widely used for establishing direct connections between two network nodes. LCP plays a vital role in the setup, configuration, and management of PPP connections, making it essential for ensuring reliable and efficient data transmission over point-to-point links. Establishing Connections Read More …
Docker GPU Access
Docker containers can effectively allow access to the GPU, particularly through the use of the NVIDIA Container Toolkit, which enables Docker to communicate with NVIDIA GPUs. This setup is essential for workloads such as AI/ML, deep learning, and data processing that require GPU acceleration to enhance performance. To enable GPU acceleration, your machine needs a Read More …
IAM – Identity and Access Management
Identity and Access Management (IAM) in Amazon Web Services (AWS) is a service that enables users to manage access to AWS resources securely. IAM allows organizations to control who can access specific resources, what actions they can perform, and under what conditions. This is crucial for maintaining security and compliance in cloud environments. Key Features Read More …
VPC – Virtual Private Cloud
A Virtual Private Cloud (VPC) in Amazon Web Services (AWS) is a logically isolated section of the AWS cloud where users can define and control a virtualized network environment. VPCs enable users to launch AWS resources, such as Amazon EC2 instances, within a virtual network that they define, providing enhanced security and control over their Read More …
