Study Notes
Indicators of Compromise (IoCs)
- IoCs are pieces of information used to detect malicious activity.
- IoCs can include specific IP addresses, URLs, unusual file changes, or unauthorized data transfers.
- IoCs represent a wide range of observable events suggesting a security breach.
Importance of Early Detection
- Early detection of malicious activity allows for more effective containment and remediation.
- Minimizes potential damage and guides incident response.
- Familiarize yourself with common IoCs and regularly review logs and alerts to improve early detection.
Malware Attacks
- Malware attacks involve software designed to infiltrate or damage computer systems.
- Indicators may include unusual CPU usage, newly appearing files, or registry changes.
- Use reputable antivirus software and keep it up-to-date to detect and remediate malware threats.
Physical Attacks
- Unauthorized physical access to equipment is a type of attack.
- Indicators include surveillance footage of unfamiliar people near secure areas, or evidence of tampering.
- Regularly audit physical access logs and implement strong physical security measures.
Network Attacks
- Network attacks like DDoS or MITM (Man-in-the-Middle) show abnormal traffic patterns or unauthorized devices on the network.
- Regularly audit physical access logs and implement strong physical security measures.
Application Attacks
- Attacks target specific software, such as SQL injection or XSS.
- Indicators include failed login attempts or unexplained database changes.
- Regularly update applications and scan for vulnerabilities.
Cryptographic Attacks
- Attacks target encryption.
- Indicators include the unexpected appearance of plain-text versions of encrypted files or failed decryption.
- Keep cryptographic systems updated and follow best practices for key management.
Password Attacks
- Multiple failed login attempts or account lockouts are indicators of password attacks.
- Implement strong password policies and use multi-factor authentication.
Indicators (General)
- Common indicators across different attack vectors include unusual account activity, unexpected data flows, altered configurations, and new or unexpected software installations.
- Always keep an eye on logs and consider using an Intrusion Detection System (IDS) for real-time analysis.
Summary
- Recognizing IoCs is crucial for early detection and mitigation of threats.
- Each attack type has unique indicators.
- Familiarity with these indicators aids quick and effective response.
Review Questions (examples)
- What are some indicators of a physical attack?
- How can network monitoring tools aid in detecting malicious activity?
Key Points (General)
- Indicators of Compromise (IoCs) are crucial for early detection.
- Different attack types have unique indicators.
Practical Exercises (examples)
- Simulate basic network attacks in a controlled environment and use network monitoring tools to detect them.
- Review access logs from a test application to identify unusual patterns.
- Vigilant monitoring and a deep understanding of IoCs prepare you to respond to various cyber threats.
