Course Description
Defensible security architecture is critical for businesses today. The persistent threat to business networks and data seems to be never-ending, with new methods of attack always in the works. Despite this heightened risk, the financial resources required to secure a network can sometimes be more than what a business can afford. How can a company preserve its trade secrets? How can they protect their customer’s data? How much should a company invest in its security infrastructure? These are the questions that businesses and IT staff face daily.
In this network security course, you will learn about several different methods to provide in-depth security to networks and the data that resides on them. We will discuss the different types of hackers, as well as their motives. You will learn about different hardware and software tools that can search for deficiencies and secure a network. Finally, you will learn the roles that topologies, disaster recovery, and the cloud play in network security.
What You'll Learn
- Explain what defensible security architecture is and the role it plays for businesses
- Recognize the applications and hardware components of security architecture, including servers and data filtration devices like NIDS and NIPS
- Identify network packets and activity associated with security breaches
- Compare different defense methods such as zero trust, perimeter defense, hybrid methods, and defense in depth
- Apply continuous monitoring, red team testing, and reactive steps to detect and block subsequent breaches
- Plan incident response, disaster recovery, evidence preservation, and internal and external communication during a breach
Key Takeaways
- Business networks and data face a persistent, evolving threat, while the financial resources needed to secure a network can exceed what a business can afford.
- Providing in-depth security requires understanding the different types of hackers and their motives, along with hardware and software tools that search for deficiencies and secure a network.
- Network topologies, disaster recovery, and the cloud each play a role in network security architecture.
- Defense methods range from the unattainable zero trust approach and the archaic perimeter approach to hybrid methods and a defense in depth strategy.
- Securing a network includes hardening security appliances, applying patches and updates, continuous monitoring and testing, and educating end users.
