Cybersecurity for Beginners - Google Cybersecurity Certificate

The demand for Security Professionals is growing significantly, with the U.S. Bureau of Labor Statistics projecting over 30 percent growth by 2030, which is higher than the average growth rate for other occupations. Global access to the internet is expanding, and more organizations are adopting digital technologies, increasing the need for security professionals. The field benefits from professionals with diverse backgrounds, perspectives, and experiences.

Security professionals and entry-level security analysts work to protect organizations and people by minimizing risks and proactively guarding against incidents. They continuously monitor systems and networks. If an incident occurs, they investigate and report findings. Their main objective is to ensure the confidentiality, integrity, and availability of information by protecting networks, devices, people, and data from unauthorized access or criminal exploitation.

Key job responsibilities for an entry-level security analyst include:

• Protecting Computer and Network systems: Monitoring internal networks, searching for system weaknesses (e.g., through penetration testing or ethical hacking), and working with IT teams to install prevention software.
• Supporting product security: Working with development teams to set up processes and systems that meet data protection needs.
• Conducting periodic security audits: Reviewing security records and activities to identify issues.

To succeed as a security analyst, a mix of transferable and technical skills is valuable.

• Transferable skills include communication (explaining technical concepts to non-technical people, reporting findings), collaboration (working with teams like engineers and program managers), analyzing complex scenarios, and problem-solving (identifying, diagnosing, and providing solutions for security issues). Critical thinking is also highlighted as a foundational skill.
• Technical skills include a basic understanding of programming languages (like Python and SQL for automating tasks and identifying errors), knowing how to use Security Information and Event Management (SIEM) tools (like Splunk and Chronicle) to collect and analyze log data, and computer forensics (investigating incidents and preserving evidence). Familiarity with operating systems like Linux is also useful for examining logs. Other tools mentioned include playbooks (manuals for responding to incidents) and network protocol analyzers/packet sniffers (like TCP dump and Wireshark) for analyzing network traffic.

The video discusses the benefits of security for organizations, such as ensuring regulatory compliance (avoiding fines and audits), maintaining and improving business productivity through business continuity planning, reducing expenses associated with data loss or downtime, and maintaining brand trust and potentially increasing revenue. Security is also essential for the ethical standing of an organization and protecting users' Personally Identifiable Information (PII) and Sensitive Personally Identifiable Information (SPII). Compromised PII or SPII can lead to identity theft, often for financial gain.

The program introduces potential entry-level job titles like security analyst or specialist, cyber security analyst or specialist, security operations center (SOC) analyst, and information security analyst.

The course explores the history of significant security attacks that shaped the industry. Early examples include the Brain virus (1986), which, despite intentions, slowed down productivity and emphasized the need for security planning, and the Morris worm (1988), which crashed computers and led to the establishment of Computer Emergency Response Teams (CERTs). More recent attacks discussed are the Love Letter attack (2000), which spread rapidly via email attachments, exploiting human error and demonstrating the power of social engineering, a manipulation technique. Social engineering attacks are increasing, especially with the rise of social media. Phishing, the use of digital communications to trick people into revealing sensitive data or deploying malware, is a common social engineering technique. The Equifax breach (2017) is highlighted as one of the largest data breaches of sensitive information, resulting in significant financial costs due to failures in fixing known vulnerabilities and underscoring the importance of preventative measures. Understanding past attacks and evolving threat actor tactics is crucial for Security Professionals.

Core security concepts are organized into eight security domains, as defined by CISSP, to categorize the work of security professionals. Gaps in one domain can affect the entire organization. The eight domains are:

1. Security and Risk Management: Focuses on defining security goals, risk mitigation, compliance, business continuity, and the law.
2. Asset Security: Focuses on securing digital and physical assets, including data storage, maintenance, retention, and destruction.
3. Security Architecture and Engineering: Focuses on optimizing data security through effective tools, systems, and processes (e.g., configuring firewalls).
4. Communication and Network Security: Focuses on managing and securing physical networks and wireless communications.
5. Identity and Access Management: Focuses on securing data by ensuring users follow policies to control access to physical and logical assets, validating identities, and documenting access roles.
6. Security Assessment and Testing: Focuses on conducting security control testing, data analysis, and security audits to monitor for risks, threats, and vulnerabilities.
7. Security Operations: Focuses on conducting investigations and implementing preventative measures.
8. Software Development Security: Focuses on using secure coding practices and incorporating security into the software development life cycle.

Organizations use security Frameworks and controls to protect themselves from threats, risks, and vulnerabilities. Frameworks are guidelines for building plans to mitigate risk and provide a structured approach to the security life cycle, which includes managing risks, following guidelines, and meeting regulatory compliance. Core components of frameworks include identifying goals, setting guidelines, implementing processes, and monitoring/communicating results. Security controls are specific safeguards designed to reduce particular risks.

Well-known frameworks and principles introduced include:

• The CIA Triad: A foundational model for considering risk, standing for Confidentiality (only authorized users access data), Integrity (data is correct, authentic, and reliable), and Availability (data is accessible to authorized users). An asset is something of value to an organization.
• The NIST Cybersecurity Framework (NIST CSF): A voluntary framework of standards, guidelines, and best practices for managing cybersecurity risk, used as a baseline by security teams.

The importance of security ethics is also covered, providing guidelines for appropriate decisions. Key ethical principles include maintaining confidentiality (protecting proprietary or private information like PII), ensuring privacy protections (safeguarding personal information from unauthorized use), and adhering to laws and regulations (rules enforced by a governing entity). Security professionals must remain unbiased and follow policies, never abusing their access privileges.

The program includes hands-on activities using common tools and programming languages and covers job search strategies. The learning is flexible, allowing completion online at one's own pace.
