Study Notes

Security Attack Classification

Types of security attacks include Fabrication, Modification, Traffic Analysis, Impersonation, Masquerade, Denial of Service (DoS), Repudiation Attacks, Replay Attacks, and Alteration Attacks.

Vulnerability and Threats

Negative consequences of threats lead to harm, motivating protective measures to reduce potential impacts.
Examples of computer harm: stolen hardware, modified files, unauthorized disclosures, and denied data access.
Asset value changes over time, affecting threat severity and the potential for harm.

Risk Management

Prioritizing the protection against serious threats within limited resources is crucial.
Risk management involves selecting threats to control and determining resource allocation for security.

Internal Security Threats

Common internal threats arise from user security ignorance, such as:
- Identity theft due to weak passwords.
- Non-compliance with company policies leading to data breaches.
- Social engineering and phishing attacks.
- Downloading malware through malicious software or applications.
- Mismanagement of email and communication tools, risking reputational harm.

Attack Methodology

Successful attacks require three critical elements: Method (how), Opportunity (when), and Motive (why).
Disrupting any of these elements can prevent the attack's success.

System Vulnerabilities

Vulnerabilities in computer systems include:
- Weak authentication processes.
- Insufficient access control measures.
- Programming errors.
- Inadequate physical security.
The attack surface encompasses all actual and potential vulnerabilities, including human errors and insider threats.

Information Security Classification

Information security classifications vary by organizational type, often categorized as Public, Sensitive, Private, or Confidential to manage data sensitivity appropriately.
