It’s important to place services where they can be easily secured. In this video, you’ll learn about security zones, attack surfaces, and connectivity. << Previous Video: Other Infrastructure Concepts Next Video: Intrusion Prevention >> I’ve worked on hundreds of different networks in my career. And everyone’s network tends to have unique characteristics. This makes sense […]

When designing a network, there are many different considerations. In this video, you’ll learn about resilience, cost, responsiveness, scalability, and more. << Previous Video: Other Infrastructure Concepts Next Video: Secure Infrastructures >> When we connect to a website or start an application, we want to login, run transactions, or use the capabilities of that website.

New network services can introduce additional security concerns. In this video, you’ll learn about virtualization, containerization, Internet of things, embedded systems, and more. << Previous Video: Network Infrastructure Concepts Next Video: Infrastructure Considerations >> If you ask an IT professional where the safest place to store data might be, some might tell you that your

Cloud-based network infrastructures can provide significant security features. In this video, you’ll learn about logical segmentation and how software defined networking can be securely deployed. << Previous Video: Cloud Infrastructures Next Video: Other Infrastructure Concepts >> One concern in networking is that it might be possible for an attacker to move from one device to

Security in the cloud is a constant challenge. In this video, you’ll learn about infrastructure as code, serverless architectures, APIs, and more. << Previous Video: Hardening Techniques Next Video: Network Infrastructure Concepts >> At this point in the evolution of cloud technologies, it’s very likely that you or your organization has one or many applications

There are many different techniques for making a system more difficult to exploit. In this video, you’ll learn about encryption, open ports, default passwords, and more. << Previous Video: Mitigation Techniques Next Video: Cloud Infrastructures >> If you take a look around your network, your servers, and other devices, you may find opportunities to make

There are many ways to prevent or reduce the impact of a cybersecurity attack. In this video, you’ll learn about patching, encryption, monitoring, least privilege, and more. << Previous Video: Segmentation and Access Control Next Video: Hardening Techniques >> Mitigation is the process of reducing the impact of a security event or a potential security

Segmenting the network can provide significant security advantages. In this video, you’ll learn about access control lists, application allow lists, and more. << Previous Video: Indicators of Compromise Next Video: Mitigation Techniques >> In order to limit the scope of any type of security event, it may be useful to segment your network into smaller

It’s important to identify an intrusion as soon as possible. In this video, you’ll learn about indicators such as account lockouts, impossible travel, resource consumption, and more. << Previous Video: Password Attacks Next Video: Segmentation and Access Control >> As an IT security professional, you’ll often be looking for any evidence that someone may have

Our passwords are often the first and last security measure we use. In this video, you’ll learn how attackers obtain our credentials using password spraying and brute force. << Previous Video: Cryptographic Attacks Next Video: Indicators of Compromise >> In your IT career, there is a possibility that you could run across an application that
