🔎 Threat Actors & Their Attack Paths

Who is attacking?

Threat Actors are the people or groups launching attacks. Mnemonic: “NO HIS” (Nation-State, Organized Crime, Hacktivists, Insiders, Script Kiddies).

How do threats reach systems?

Threat Vectors are the attack paths used by threat actors. Mnemonic: “MFWDVN” (Messages, Files, Websites, Devices, Vendors, Networks).

Understanding Servlet Architecture for Java Web Applications

Servlet architecture is a core component of Java EE (Enterprise Edition) used for building dynamic web applications. A Servlet is a Java class that runs on a web server and acts as a middle layer between client requests (typically from a browser) and server responses (usually from a database or application logic).

What is a Servlet?

A Servlet is a Java class used to handle HTTP requests and responses in web applications. It runs on a server, receives requests from a client (usually a browser), processes them (e.g., reads form data, interacts with a database), and sends back a dynamic response (like HTML or JSON).

Key Components of Servlet Architecture

• Client (Browser): Sends an HTTP request

CBCT

Response to Orthodontic Pressure

Light Pressure (<1 second to Hours)

• Less than 1 second: PDL fluid is incompressible; alveolar bone bends, and a piezoelectric signal is generated.
• 1-2 seconds: PDL fluid is expressed; the tooth moves within the PDL space.
• 3-5 seconds: Blood flow within the PDL is partially compressed on the pressure side and dilated on the tension side.
• Minutes: Blood flow is altered, and oxygen tension begins to change.
• Hours: Metabolic changes and chemical messengers affect cellular activity.
• Less than 4 hours: Cellular differentiation begins within the PDL.
• 2 days: Tooth movement occurs as osteoclasts and osteoblasts remodel bone.

Heavy Pressure (<1 second to 7-14 days)

• Less than 1 second: PDL fluid is incompressible; alveolar

Understanding Your Prescription Label

1. Pharmacy Name and Address: Displayed at the top of the prescription label is the name and address of the pharmacy that filled the prescription.

2. Pharmacy Phone Number: Found near the pharmacy’s name and address.

3. Prescription Number: A key element of the label, needed to refill the prescription.

4. Prescribing Doctor and Fill Date: The doctor’s name appears on the label (location may vary), along with the date the prescription was filled, which can affect insurance coverage.

5. Patient’s Name: Clearly shows who the prescription is for; sometimes includes the patient’s address.

6. Directions for Taking the Drug: One of the most important parts of the prescription label. These instructions tell exactly... Continue reading "Mastering Pharmacy Labels and Essential Health Supplies" »

This educational resource details Ethereum, a decentralized blockchain platform launched in 2015, focusing on its key features, accounts, smart contracts, transactions, and consensus mechanisms.

Ethereum Fundamentals

Ethereum is a blockchain platform that supports smart contracts—immutable computer programs executed on the Ethereum Virtual Machine (EVM). It uses Ether (ETH) as its native cryptocurrency to pay for transaction processing and smart contract execution.

Ethereum Accounts and Wallets

Account Types

• Externally-Owned Accounts (EOAs): Controlled by private keys, used primarily for transactions like ETH transfers. Public keys are derived using Elliptic Curve Cryptography (ECC).
• Contract Accounts: Controlled by smart contract code, deployed

Pharmacology Fundamentals

Pharmacokinetics: What the Body Does to the Drug

Phases:

1. Absorption – How a drug enters the bloodstream

2. Distribution – How a drug travels through the body

3. Metabolism – How a drug is broken down (mainly in the liver)

4. Excretion – How a drug leaves the body (mainly through the kidneys)

🧠 Memory Trick: ADME — Absorb, Deliver, Metabolize, Exit

Pharmacodynamics: What the Drug Does to the Body

• Describes how a drug works at the target site

• Involves receptor binding, enzyme interactions, and therapeutic vs. side effects

Examples:

• Beta blockers bind to beta receptors → slow heart rate

• Insulin binds to insulin receptors → lowers blood sugar

Drug Release Types: ER, IR, SR, XL, CR
