Study Notes
Principles of Security - 1911194, Topic 2: The Need of Security
- Learning Objectives: Discuss organizational need for info sec, explain shared responsibility of departments, list/describe threats to info security, and discuss Linux operating systems, distributions, and their use in security.
Business Need for Security
- Information security performs four vital functions for organizations:
- Protecting the organization's ability to function
- Protecting data and info the organization collects and uses
- Enabling safe operation of applications running on IT systems
- Safeguarding technology assets from threats and attacks
Protecting Functionality of an Organization
- Organizations need security management, alongside IT departments, to implement and follow security plans.
- Management is responsible for facilitating security programs.
- Implementing information security requires strong management, not just technology, and sound management strategies.
- Security failures disrupt business operations and incur high costs.
Protecting Collected and Used Data
- Organizations rely on data to deliver value to customers.
- Safeguarding data during transmission, processing, and storage is crucial for information security.
Enabling Safe Application Operation
- Organizations require environments protecting applications using IT systems.
- General management oversees operations by different departments, ensuring compliance with security plans coordinated with IT departments. .
Safeguarding Technological Assets
- Organizations must use secure hardware and software appropriate for their size and scope.
- Additional security measures may be needed as the organization grows.
- General management must continuously supervise and maintain proper infrastructure development; IT coordination is essential.
Threats and Attacks
-
Key Term (Attack): An intentional or unintentional act compromising information and supporting systems. Attacks can be active or passive, and direct or indirect.
-
Active Attacks: Attacker modifies message content or affects system operations (e.g., changing data streams, creating false statements.) Examples include viruses, worms, and Trojan Horses.
-
Management Reporting: Management needs insights into the types of threats (people, applications, data, info systems, physical assets).
-
Increasing Threats: Despite increasing security, threats and attacks also increase, particularly due to global internet user growth.
12 Main Threats on Information Security
- Compromises on intellectual property (IP).
- Deviation in quality of service.
- Espionage or trespass (includes hackers, expert hackers, unskilled hackers, crackers.)
- Forces of nature.
- Human error or failure (includes disclosing data, erroneous data entry, accidental data deletion, unprotected storage).
- Information extortion.
- Sabotage or vandalism.
- Software attack (Rootkits, Denial of Service -DoS- , distributed Denial of Service -DDoS).
- Technical hardware failure or error.
- Technological obsolescence.
- Theft and physical attacks.
Defense in Depth (DiD)
- Defense in Depth is an information security approach with layered security mechanisms, protecting confidentiality, integrity, and availability of networks and data within the system.
Linux Operating System
-
Linux is a modular Unix-like operating system, based on principles from the 1970s and 1980s.
-
It's open-source so users can create their own distributions.
-
Examples of well known Linux Distributions include: Ubuntu, Fedora, Linux Mint, Debian, Kali Linux, and CSI Linux.
-
Different Distributions are focused on different functional uses from ethical hacking to digital forensics.
-
Web sites such as www.Linux.org and www.Kali.org offer relevant information and support.
