We rely on email as one of our most common methods of communication. In this video, you’ll learn about SPF (Secure Policy Framework), DKIM (Domain Keys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting, and Conformance). << Previous Video: Secure Protocols Next Video: Monitoring Data >> If you check your spam folder right now, you’ll […]

Encrypting network traffic is an important security best practice. In this video, you’ll learn about protocol and port selection, transport methods, and VPN tunnels. << Previous Video: Operating System Security Next Video: Email Security >> Whether you’re sending traffic over a wired network or a wireless network, you still need to make sure that everything

Operating systems are important resources to secure. In this video, you’ll learn about Active Directory, Group Policy, and Security-Enhanced Linux (SELinux). << Previous Video: Web Filtering Next Video: Secure Protocols >> If you’re working in an environment with many Windows devices, then you’re probably taking advantage of Active Directory. Active Directory is a database containing

Many filtering methods are available to protect against attacks. In this video, you’ll learn about content filtering, URL scanning, proxies, DNS filtering, and more. << Previous Video: Firewalls Next Video: Operating System Security >> Many organizations have a firewall that provides them a way to allow or disallow access from certain applications. But what if

Firewalls are an important part of any security protection strategy. In this video, you’ll learn about next-generation firewalls, firewall rules, screen subnets, and more. << Previous Video: Security Tools Next Video: Web Filtering >> A network-based firewall is an appliance that sits inline in your network and makes decisions about whether traffic should be allowed

Security administrators have many tools to help protect network resources. In this video, you’ll learn about Security Content Automation Protocol (SCAP), secure baselines, SIEMs, and more. << Previous Video: Security Monitoring Next Video: Firewalls >> On your enterprise network, there are probably many different security tools. You might have next generation firewalls, intrusion prevention systems,

There are many methods for monitoring and reacting to security events. In this video, you’ll learn about log aggregation, scanning, reporting, alerting, and more. << Previous Video: Vulnerability Remediation Next Video: Security Tools >> Attackers are constantly trying to gain access to our systems and services. So for that reason, we also have to constantly

Once a vulnerability is identified, a security professional is required to mitigate the issue. In this video, you’ll learn about patching, insurance, segmentation, compensating controls, and more. << Previous Video: Analyzing Vulnerabilities Next Video: Security Monitoring >> In the vast majority of cases where a vulnerability has been identified, it can easily be mitigated by

Identifying and analyzing vulnerabilities can be a relatively complex process. In this video, you’ll learn about vulnerability databases, classification, exposure factor, risk tolerance, and more. << Previous Video: Penetration Testing Next Video: Vulnerability Remediation >> One of the challenges when looking through log files or receiving reports of vulnerability scans is that you’ll often have

Penetration tests can simulate an attack to exploit vulnerabilities. In this video, you’ll learn about rules of engagement, the exploitation process, responsible disclosure programs, and more. << Previous Video: Threat Intelligence Next Video: Analyzing Vulnerabilities >> Penetration testing or pen testing is a process where we simulate an attack on our own systems. This is
