Introduction to CyberSecurity

Introdution

• Cybersecurity is a critical field in today’s digital world, focused on protecting systems, networks, and data from digital attacks. - These attacks often aim to access, change, or destroy sensitive information, interrupt normal business processes, or implement ransomware attacks.
• Cybersecurity measures are essential to protect both individuals and organizations from potential threats.
• This includes
  • Securing data in transit and at rest
  • Securing hardware and software
  • Network security
  • Ensuring recovery from a data breach or other incidents.
• Cybersecurity covers a wide range of areas including application security, information security, network security, disaster recovery, and more.
• As our reliance on digital platforms grows, so does the importance of robust cybersecurity measures.
• Cybersecurity is a broad field that encompasses several categories, each focusing on a specific aspect of security. Here are some of the main categories:

1. Network Security:
   • Protects the integrity and usability of network and data by preventing and monitoring unauthorized access, misuse, modification, or denial of the network and network-accessible resources.
2. Application Security:
   • Focuses on keeping software and devices free of threats by identifying, fixing, and enhancing the security of software applications.
3. Information Security:
   • Protects the integrity and privacy of data, both in storage and in transit.
4. Operational Security (OPSEC):
   • Involves the process of identifying and protecting sensitive information that could be used by adversaries to cause harm.
5. Disaster Recovery and Business Continuity:
   • Dictates how an organization responds to a cyber-security incident or any other event that causes the loss of operations or data.
6. End-User Education:
   • Addresses the most unpredictable cyber-security factor: people. Users must understand the procedures for protecting personal and professional data.
7. Cloud Security:
   • A subset of cybersecurity that focuses on securing data, applications, and infrastructures in the cloud.
8. Mobile Security:
   • Focuses on protecting personal and business information stored on mobile devices.
9. Data Loss Prevention (DLP):
   • Strategies for ensuring that end users do not send sensitive or critical information outside the corporate network.
10. Intrusion Detection Systems (IDS) or Intrusion Prevention Systems (IPS):
    • Tools that monitor network traffic for suspicious activity and issues alerts when such activity is discovered.
