Minimize & Maximize Multiple Windows

 Shortcuts to minimize & maximize multiple windows

Here are a few shortcuts to make you more efficient. 

Having trouble closing an app - Taskkill

 Close an app using Tasklist & Taskkill

We have all run into this at one time or another. You have an app that you cannot close via the app or with the Task Manager. Here is an easy way to do this without rebooting your system.

Access Control Methods

 ABAC, DAC, MAC, Role-BAC, Rule-BAC

ABAC (Attribute-Based Access Control)

The most fine-grained access control.

Access is based on a combination of subject and object attributes

• Operating system
• IP address
• Up-to-date patches
• Up-to-date antimalware
• Employee's identity
• Time of day
• Location
• Type of device

DAC (Discretionary Access Control)

• Based on the owner of the file or folder
• The owner decides who gets access and the type of access
• Windows, Linux, and UNIX use a DAC method

MAC (Mandatory Access Control)

• Each object is assigned a classification label
• Each subject is assigned a clearance level (such as Confidential, Secret, or Top Secret)
• A subject with the label "Secret" would be unable to access "Top Secret" data as it would be above its clearance level.
• Also, based on "Need to know," in other words, not everything will they have access to at its security level. 

RBAC (Role-Based Access Control)

• Based on your job function (role)
• Group-based security
• Group examples: Accounting, HR, IT, Sales. etc

RBAC (Rule-Based Access Control)

• System enforced rules
• Some rule triggers the access control
• Time of day 
• Conditional access is a form of rule-based access control
• UAC (User Account Control - Windows) and sudo - Linux are examples of conditional access

Netstat - Native to Linux / Windows

 NETSTAT

Netstat is a tool built into both Linux and Windows, but the syntax is different between the two operating systems.

Several ways this local command line tool can be utilized:

• See what ports (services) are in a listening state, both TCP and UDP ports.
• See what files are being accessed and which computers are involved.
• See if any systems are connected before rebooting a server.
• See what process established the connection (such as Zoom, Firefox, Chrome, Edge, etc.)
• Display ethernet statistics
• Display the owning process ID
• Display the routing table

Tokenization

 Credit Cards - Tokenization

Tokenization is used to make it easy to reorder a credit card. One such method is the vendor storing the credit card information (not in plaintext) for monthly or yearly subscriptions. 

This process can replace part or all of the original data. The token is located on a token server.

Tokenization is a security technique that replaces sensitive data with a non-sensitive substitute called a token. Tokens are unique identifiers that link to the original data but cannot be deciphered to access the original information.

Tokenization is used in many areas, including:

Payment processing

Tokenization protects credit card and bank account numbers by replacing them with tokens. This removes the connection between the transaction and sensitive data, making transmitting data over wireless networks safer.

Speech recognition

Voice-activated assistants like Siri or Alexa use tokenization to process spoken words. When you ask a question or command, your spoken words are converted into text, which is then tokenized.

Commodities

Tokenization can turn ownership of commodities like oil, gold, or agricultural products into on-chain tokens, making the market for these assets more liquid and accessible.

Tokenization is also known as "masking" or "obfuscation."
