Cyber Security 101 - Introduction

Explore the introductions and foundations of cybersecurity, uncover basic concepts and principles that guide the industry, and examine the CIA triad.

Explore the essentials of information security, including confidentiality, integrity, and availability, and learn how technical, administrative, and physical controls safeguard data from unauthorized access, disclosure, and misuse.

Explore the foundations of cybersecurity, including confidentiality, integrity, and availability, plus risk management, awareness and training, and regulatory compliance to protect information and maintain trust.

Explore the types of cyber attacks and the differences between active and passive cyber attacks, and examine how these attacks are conducted.

Active cyber attacks are underway and threaten businesses, governments, and individuals through malware, ransomware, phishing, or denial of service, with severe financial, data, reputational consequences and even physical harm.

Explore passive cyber attacks, where attackers observe targets, perform passive reconnaissance, and sniff data to collect passwords and credit card numbers, while remaining difficult to detect.

Explore the daily cyber threats facing individuals and businesses, including social engineering and ransomware, and assess their impacts on individuals and organizations.

Explore cyber threats, malware, and ransomware, and how they encrypt data and demand ransom. Learn proactive defenses with antivirus, patches, strong passwords, multi-factor authentication, and regular backups.

Identify social engineering attacks like phishing, smishing, and vishing, and learn to protect passwords and confidential data through security awareness training, two-factor authentication, and anti-phishing software.

Learn how deepfakes and insiders threaten organizations with realistic audio and video forgeries and privileged access abuse. Implement access controls, monitor behavior, conduct audits, and educate employees to prevent misuse.

Analyze how supply chains enable efficiency while threatening information security through shared sensitive data, exemplified by the 2013 Target breach, and learn steps to protect data and reputation.

Examine cyber threat actors, their motives and techniques, to understand their behavior. Analyze nation state actors, ideologues, and cyber criminals as key threat groups driving attacks.

Nation-state actors, including governments and intelligence agencies, threaten information security through espionage and disruptive cyber attacks on infrastructure, highlighting the need for robust cybersecurity, training, and threat intelligence coordination.

Cyber criminals use the internet to steal data, disrupt operations, and access confidential information, employing phishing, malware, and ransomware. Strengthen information security with firewalls, antivirus, encryption, updates, and regular training.

Ideologues, deeply committed to their beliefs, threaten information security through social engineering to access data or install malware. Mitigate with robust security, training, access controls, and audits.

Discover five best practices that organizations should implement to keep digital assets safe. Explore encryption and other strategies that can boost your overall cyber security posture.

Regularly update and patch software to reduce security risks by addressing vulnerabilities, improving protection, compatibility, and overall performance.

Learn how encryption converts plain text into coded form and protects confidentiality and integrity by restricting access to authorized parties across messaging, email, and online transactions.

Implement and communicate comprehensive security policies and procedures to protect data systems and networks, train employees, and ensure access control, password management, network security, incident response, and recovery.

Back up data regularly to protect against loss from hardware failure and cyber attacks. Store backups in secure locations and test recovery to ensure quick restoration and disaster resilience.

Use anti-malware and antivirus software to protect your computer from malware and viruses, detect and remove threats, block malicious websites and emails, and perform scans and updates to enhance security.

Implementing a disaster recovery plan defines steps to recover from catastrophes, minimize downtime, and protect data by backing up offsite and ensuring essential operations, resources, and clear communication.

Explore the diverse roles in the cyber security industry, from penetration testing to security engineering, and identify the skills and talents needed to fit these roles.

Explore the role of a penetration tester, or ethical hacker, who identifies vulnerabilities through simulated attacks and conducts security assessments with vulnerability scans, manual testing, and risk-based recommendations.

Protect data and information systems by identifying risks, developing and implementing security policies and procedures, and monitoring networks to detect and prevent breaches in a rapidly evolving threat landscape.

Security operations center analysts detect, analyze, and respond to security incidents in real time, monitoring threats, malware, and vulnerabilities with siem and ids/ips tools to protect assets, data, and systems.

Design, build, and maintain security infrastructure to prevent unauthorized access and protect confidential data, install and monitor firewalls and antivirus, and collaborate with IT teams to keep protocols compliant.

A security manager develops and implements policies to protect people and assets. They identify threats, conduct risk assessments, and coordinate physical and cyber security and emergency response planning.

Learn how secure coders integrate security into the software development life cycle, identify and mitigate vulnerabilities, and prevent data breaches through secure coding practices.
