This is all of the posts dedicated to sharing the IT knowledge I have accumulated through the years and through all of the positions, companies, and projects. As I say, I am not the sharpest tool in the shed, but my shed and tool collection is a lot larger than the average bear, Boo Boo.
ACE – Access Control Entries
The Building Blocks of Permissions In the realm of Identity and Access Management, controlling who can access what is paramount. While Access Control Lists (ACLs) provide the structure for managing permissions, the individual permissions themselves are defined within Access Control Entries (ACEs). Understanding ACEs is crucial for IT students to grasp the fine-grained control that Read More …
Notes :: Pre-Authentication Remote Code Execution
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 …
TARA – Threat Analysis and Risk Assessment
Threat Analysis and Risk Assessment (TARA) is a critical process in cybersecurity that helps organizations identify, evaluate, and prioritize potential threats to their information systems and data. As cyber threats continue to evolve, understanding TARA is essential for protecting sensitive information and maintaining the integrity of systems. This summary will provide an overview of TARA Read More …
Tools – BEAR: Simulating Advanced Persistent Threats for Cybersecurity Education
For aspiring and new information security professionals, gaining practical insight into real-world attack methodologies is paramount. One tool that offers a unique perspective into advanced threat simulation is “BEAR,” a project found on GitHub. Unlike typical vulnerability scanners or compliance tools, BEAR is a compilation of Command and Control (C2) scripts, payloads, and stagers explicitly 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 …
