Free CompTIA Security+ Training

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

Poorly implemented cryptography can often be the source of an attack. In this video, you’ll learn about downgrade attacks, SSL stripping, and hash collisions. << Previous Video: Application Attacks Next Video: Password Attacks >> Cryptography is a technology we use many times a day. But we often don’t even think about what’s happening behind the

Our applications can be the weakest links in our security armor. In this video, you’ll learn about privilege escalation, directory traversal, and more. << Previous Video: Malicious Code Next Video: Cryptographic Attacks >> An injection attack is a very common way to attack an application because an attacker can easily add additional malicious code to

An attacker often writes their own software to exploit a vulnerability. In this video, you’ll learn about malicious code and how it has been used to gain access to some of the largest networks in the world. << Previous Video: Replay Attacks Next Video: Application Attacks >> As we’ve already discussed in this course, attackers

Some attacks can reuse our network communication to gain unauthorized access. In this video, you’ll learn about pass the hash, session hijacking, and other ways to implement a replay attack. << Previous Video: On-path Attacks Next Video: Malicious Code >> A common flow of network traffic is from a client to send information to the

An on-path attack allows an attacker to intercept and redirect critical network traffic. In this video, you’ll learn about the processes used to implement an on-path attack. << Previous Video: Wireless Attacks Next Video: Replay Attacks >> An on-path attack allows an attacker to sit between two devices and watch all of the traffic go
