MIS Program Algorithms Chapter 5

Study Notes

Developing an optimal MIS program requires professional methods to avoid the "Rush to Code" problem.
Algorithms are essential for writing code and provide a blueprint for implementing solutions in diverse programming languages and environments.
Effective program algorithms are clear, concise, and efficient, leading to better code readability, maintainability, and performance.

Algorithms enable programmers to express algorithmic ideas clearly and understandably.
Algorithm design helps programmers focus on the logic and flow of their algorithms without being distracted by syntactical nuances of a particular programming language.

Flowcharts are graphical representations of algorithms or processes, using symbols and connectors to illustrate the flow of control within a program.
Flowcharts provide a visual roadmap for understanding the logical sequence of operations, making them an invaluable tool for understanding problems and easy to code.
Examples of flowcharts include calculating the summation of two numbers and determining if the weather is above or below freezing.

Cybersecurity is crucial in contemporary times due to threats, hacking, and attacks in the digital landscape.
Management Information Systems (MIS) play a pivotal role in various aspects of our digital existence, and robust security measures are essential to mitigate challenges.

Cybersecurity is the practice of protecting systems, networks, and programs from digital threats and attacks.
Cybersecurity attacks include malware, phishing, ransomware, man-in-the-middle (MitM) attacks, denial of service (DoS) attacks, SQL injection, and zero-day exploits.

Risk assessment is essential to identify and prioritize potential risks to the organization's information and systems.
Security policies should establish rules and procedures to protect an organization's information assets.
Encryption uses cryptographic techniques to protect data confidentiality and integrity.
Regular updates and patch management are necessary to protect against vulnerabilities.
Monitoring and detection are crucial to continuously monitor systems for suspicious activity and potential threats.

Creating strong passwords is a crucial aspect of MIS cybersecurity, with criteria including length, complexity, and unpredictability.
Examples of strong passwords include 9oR5kMt@ and KoR@5r_4.
Online tools are available to test and check the strength of passwords.

Firewalls are used to protect computer networks from unauthorized access.
Examples of hardware firewalls include Cisco ASA, Fortinet FortiGate, and Palo Alto Networks.
Software firewalls are suitable for individual PCs, servers, and small networks, while hardware firewalls are suitable for large computer network systems.

Encryption is a method of converting plaintext into ciphertext to ensure confidentiality, secure communication, and data protection.
Encryption involves two main processes: encryption (ciphering) and decryption (deciphering).
There are two primary types of encryptions: symmetric encryption and asymmetric encryption.
Symmetric encryption uses the same key for both encryption and decryption, while asymmetric encryption uses a pair of keys.
