Summary

Cybersecurity Certification Study Group Overview

Winton introduces himself as the educator for the session, highlighting his extensive cybersecurity certifications and professional experience. He explains the purpose of the study group, which includes reviewing how to study and pass cybersecurity certifications, create resumes, and secure jobs in the field. Winton emphasizes the importance of networking and offers to connect with participants on LinkedIn or through one-on-one calls scheduled via the Safer Internet Project website.

Cysa+ Certification and Security Operations

Winton introduces the Cysa+ (Cybersecurity Analyst Plus) certification, highlighting its importance in the cybersecurity field. He explains that the certification is recognized by the DoD and can lead to various job opportunities such as security analyst and SOC analyst. Winton emphasizes that the exam tests practical thinking and scenario-based problem-solving, and obtaining the Cysa+ also renews the Security+ certification for three years. He then begins to discuss Domain 4: Security Operations, which comprises 33% of the exam and focuses on real-time monitoring, detection, and response skills.

Security Techniques and Baseline Standards

Winton outlines the roadmap for the hour, covering nine major objectives aligned with CompTIA's list. He begins with security techniques for computing, emphasizing the importance of secure baselines, hardening, and secure coding. Winton explains that baselines are the minimum security standards for configuring inventory, which need to be continuously improved to keep up with industry changes. He then discusses hardening targets, noting that different asset classes require different controls, and emphasizes the importance of matching controls to context for the CompTIA exam.

Wireless Security and Device Management Essentials

Winton discusses wireless security protocols and mobile device management. He emphasizes that WPA3 Personal with SAE is the current gold standard for wireless security, superior to WPA2 and WEP. For enterprise deployments, he mentions 802.1X with RADIUS as the preferred method. Winton also covers common wireless attacks like evil twin and de-authentication floods. Regarding mobile device management, he stresses the importance of understanding acronyms such as BYOD, COPE, and CYOD, and considering various scenarios and risks associated with different device ownership models.

Application Security Testing Methods Overview

Winton explains the differences between static application security testing (SAST) and dynamic application security testing (DAST), emphasizing that SAST scans code before runtime while DAST interacts with live applications. He also discusses fuzzing, which tests applications by inputting malformed data to expose potential crashes. Winton highlights the importance of sandboxing for isolating risky processes and explains the distinction between behavioral and signature-based threat detection methods, noting that behavioral analytics are better for unknown threats while signatures are useful for known threats.

Asset Lifecycle Management and Tracking Essentials

Winton discusses asset management essentials, emphasizing the importance of tracking the lifecycle of assets from acquisition to retirement. He uses his personal experience with a Macbook to illustrate the value of timely asset retirement. Winton then outlines asset lifecycle controls, including vendor vetting, firmware integrity checks, and access management based on ownership and data classifications. He concludes by explaining various tagging technologies for asset inventory, such as barcodes for static assets and RFID for mobile equipment, and stresses the importance of unifying all asset information into a single view for easier auditing and incident management.

Vulnerability Management Lifecycle and Prioritization

Winton discusses the vulnerability management flow, emphasizing that it's a continuous loop of identifying, analyzing, responding, validating, and reporting. He stresses the importance of context in assessing vulnerabilities, explaining that the same threat can have different implications depending on the environment. Winton then explains various scan types, including authenticated and non-authenticated scans, and their use cases. He concludes by highlighting the significance of prioritizing vulnerabilities using CVSS scores and environmental factors, noting that context often matters more than raw scores when assessing risks.

Advanced Security Systems and Monitoring

Winton discusses security, alerting, and monitoring systems, focusing on SIM, SOAR, and UEBA. He explains how these systems work together to transform raw logs into actionable intelligence at machine speed. Winton also covers file integrity monitoring, emphasizing its importance in maintaining data integrity and preventing unauthorized changes. He touches on netflow analysis and packet capture for breach detection and evidence gathering. Lastly, Winton discusses enterprise capabilities, highlighting how prevention feeds detection and the importance of network segmentation in limiting lateral movement during security incidents.

Identity and Access Management Essentials

Winton discusses identity and access management, emphasizing the importance of multi-factor authentication (MFA) and its various methods. He notes that biometrics are currently the strongest form of MFA, while SMS is considered weak. Winton also explains privileged access management (PAM), highlighting the principles of least privilege and just-in-time elevation. He concludes by stressing the importance of automation in security, the need for a "shift left" approach to vulnerabilities, and the value of human oversight in automated systems.

Digital Forensics and Incident Response Essentials

Winton discusses key aspects of digital forensics and incident response. He emphasizes the importance of preparation, proper camera placement for threat detection, and following the order of volatility when collecting evidence. Winton also highlights the significance of maintaining a clean chain of custody, understanding data sources for investigation, and implementing three main pillars: visibility, analytics, and automation. He concludes by mentioning supporting elements such as least privilege, regular drills, and continuous improvement for mature processes.

Cybersecurity Scenarios and False Positives

Winton discusses two cybersecurity scenarios with the group. In the first, he explains that a credentialed vulnerability scan flagging a missing patch on a Linux web server, which manual verification shows is actually installed, is an example of a false positive. He then presents another scenario involving automated containment of malware on endpoints, explaining that a SOAR platform can ingest alerts from a SIEM and trigger EDR actions. Winton concludes by announcing the next session in 6 days and suggests they might discuss the CASP+ certification next week.
