What are Docker Images? Docker images are read-only templates that contain everything needed to run a container, including the application code, runtime, libraries, dependencies, and configuration files. They are built using a declarative file called a Dockerfile, which specifies the instructions for creating the image. Docker images are stored in a registry, such as Docker Hub, from where they can be pulled and run on any Docker-enabled host.
The key characteristics of Docker images are:
Script VS Program The terms “script” and “program” are often used interchangeably, but there are some distinctions between them:
Script: A script is a type of program that is usually written in a scripting language. Scripts are typically used to automate tasks or perform specific functions within a larger software system. Scripts are often interpreted rather than compiled, meaning they are executed line by line by an interpreter. Examples of scripting languages include JavaScript, Python, Perl, and Bash.
Chay published on Cryptography Cryptography is the process of encoding data to protect it from unauthorized access, maintain its privacy, and guarantee its secrecy. It involves the use of mathematical principles and algorithms to transform data into a form that appears meaningless to anyone who does not possess the appropriate key or decryption method.
The main purposes of cryptography are to:
Ensure the confidentiality of digital data by encoding it so that only authorized parties can access it.
Chay published on Cloud Computing Cloud computing refers to the delivery of computing services, including servers, storage, databases, networking, software, and more, over the internet (“the cloud”). Instead of owning and maintaining physical servers or infrastructure, users can access these services on a pay-as-you-go basis from a cloud provider. This model offers flexibility, scalability, cost-effectiveness, and the ability to access resources from anywhere with an internet connection.
Here are some pros and cons of cloud computing:
Chay published on IOT or IOE IoT or IoE stands for Internet of Things or Internet of Everything. Here are some key things to know about IoT/IoE:
IoT refers to the network of physical devices, vehicles, home appliances and other items embedded with electronics, software, sensors, actuators, and network connectivity which enables these objects to connect and exchange data.
IoE expands on IoT to include not just “things” but people, processes and data as well.
Business Continuity Planning (BCP): Business Continuity Planning (BCP) is the process of creating a strategy to ensure that essential business functions can continue during and after a disaster or disruption. BCP involves identifying potential risks, developing plans to mitigate those risks, and implementing measures to maintain critical operations. BCP does not concentrate on restoring full business activities and services. It focuses on critical products and services that the organization provides and ensures those important areas can continue to operate even on reduced level of performance until business returns to normal.

Chay published on Mobile Attack Anatomy Here are a few common types of mobile attacks:
Malware/Virus Attacks - Malicious software is installed on a device without the user’s consent or knowledge. It can steal data, monitor activity, or gain control of the device. Viruses, trojans, ransomware are examples.
Phishing Attacks - Deceptive communications trick users into sharing sensitive info like passwords, bank details, etc. Phishing sites or texts/calls impersonate trusted brands to steal credentials.
Chay published on Wireless Terminology GSM: A universal system used for mobile transportation for wireless networks worldwide. Bandwidth: Describes the amount of information that may be broadcast over a connection. Access point (AP): Used to connect wireless devices to a wireless/wired network. BSSID: The MAC address of an AP that has set up a Basic Service Set (BSS) identifier. ISM band: A set of frequencies for the international industrial, scientific, and medical communities. Hotspot: A place where a wireless network is available for public use.
Introduction In today’s digital age, information security threats are a constant concern for organizations of all sizes. The National Institute of Standards and Technology (NIST) offers a powerful tool to combat these threats: the Risk Management Framework (RMF). This framework provides a structured, yet adaptable, approach to managing security and privacy risks.
This article explores the NIST RMF’s seven key steps, empowering you to implement a robust risk management strategy.
