Study Notes

Secure Programming Overview

Secure programming aims to create software free from vulnerabilities.
A secure organization has layered security, including physical, personal, operational, communication, and network security.
Information security protects information and its systems and hardware.
- Essential resources include policy, awareness, training, and technology.
- The CIA triangle (Confidentiality, Integrity, Availability) is a key standard.

Critical Characteristics

Confidentiality: Prevents unauthorized disclosure or exposure of information.
Integrity: Ensures the data's completeness and accuracy (whole, uncorrupted).
- Uses methods like checksums, error correction, and retransmission.
Availability: Guarantees timely access to information and services when needed.

Components of an Information System

Software: Often the most complex and vulnerable component.
- Exploitations are a significant attack target.
Hardware: Physical security is paramount.
- Laptop and flash memory security is crucial.
Data: Highly valuable asset, frequently targeted for attacks.
People: The weakest link, requiring thorough training to prevent social engineering attacks.
Procedures: Inadequate procedures lead to data integrity threats.
Networks: Traditional security measures (locks and keys) are insufficient in modern network environments.

Securing Components

Computers can be targeted as both a subject and object of an attack.
- Attacks can use compromised systems to target other systems (indirect).
Types of attacks:
- Direct: Hacker directly accesses a system.
- Indirect: Compromised system exploited to launch an attack.

Threats

A threat is anything that poses danger to organization assets.
Management must be aware of various potential threats and address them through policy, education, training, and technological controls.

Attacks

An attack is a deliberate action exploiting vulnerabilities.
- It can damage or steal information and physical assets.
- Vulnerability is an identified weakness in the system.
- An exploit is a technique for exploiting a vulnerability.
A vulnerability is an identified weakness in the system preventing proper functioning of controls.

Basic Problems

User awareness and understanding of risks are often inadequate.
Human errors, especially under stress or overload, create security vulnerabilities.
Complex systems can mislead users, leading to incorrect actions.
Performance degradation as a side effect of security measures should be considered.
Users can be tricked into engaging in attacks and compromised systems.
Experienced users are also vulnerable, such as copying authentication links or attachments.

Roots of Insecurity

Current defensive strategies are often reactive.
The internet's rapid growth has strained security talent.
The availability of complex software without secure coding practices contributes to the problem.

ICT Security

ICT (Information and Communication Technologies) are crucial for access to information via telecommunications.
ICT security protects an organization's ICT system through product, service, and behavior controls.
Hardware, OS and applications, and communications (including cloud – optional) are primary components of any ICT system.
