Study Notes
Security Problems
- Cybersecurity awareness among employees is often lacking, leading to security challenges.
- Security attack techniques are evolving and becoming more sophisticated.
- Increased number of insecure network devices, such as mobile gadgets and IoT devices.
- Common security issues include misconfigurations of systems and applications.
Computer Security Concepts
- Computer security involves protecting automated information systems to maintain integrity, availability, and confidentiality of resources like hardware, software, and data.
Vulnerabilities, Threats, and Attacks
-
Platforms with vulnerabilities include:
- On-Premises Platforms: Security concerns arise from inadequate configurations and numerous external entry points like USB drives and email.
- Cloud Platforms: Vulnerabilities often stem from misconfigurations and constant exposure to threats due to remote accessibility.
-
Configuration Vulnerabilities: Weak configurations arise from improperly implemented security settings and delays in applying patches to firmware or software.
-
Zero-Day Vulnerabilities: Exploited by attackers before discovery, these are highly dangerous due to the absence of available patches.
-
Threats are potential damaging events, with cybersecurity threats exploiting existing vulnerabilities. Examples include unauthorized server access, ransomware, and Denial of Service (DoS) attacks.
-
Threat Actors: Individuals or entities responsible for cyber incidents, targeting users, enterprises, and governments. Categories include script kiddies, hacktivists, state actors, and insiders.
-
Types of Attacks:
- Passive Attacks: Focus on gathering information without altering system resources.
- Active Attacks: Aim to modify system resources or disrupt operations, with categories including fabrication, modification, and interruption.
-
Attack Vectors: Pathways used by threat actors to breach systems. Common vectors include:
- Email: Main delivery method for malware, often through deceptive attachments or links.
- Wireless: Vulnerable to interception if not adequately protected.
- Supply Chain: Risk of malware insertion during production and storage phases.
Computer Security Trends
- The financial impact of cybercrime is continually rising, with costs expected to escalate further.
- Cyber attacks are projected to persist indefinitely, posing ongoing threats to organizations.
- Live cyber attack maps provide real-time visualization of ongoing threats and incidents.
