Implementing Certificates, TLS, HTTPS and Opportunistic TLS
Transport Layer Security (TLS) is a widely used encryption protocol which enables parties to communicate securely over the internet. Through the use of certificates and Public Key Infrastructure (PKI), parties can identify each other through a trusted intermediary and establish encrypted tunnels for the secure transfer of information.
How to Combat Fake Emails
Organisations can reduce the likelihood of their domains being used to support fake emails by implementing Sender Policy Framework (SPF) and Domain-based Message Authentication, Reporting and Conformance (DMARC) records in their Domain Name System (DNS) configuration. Using DMARC with DomainKeys Identified Mail (DKIM) to sign emails provides further safety against fake emails. Likewise, organisations can better protect their users against fake emails by ensuring their email systems use and apply SPF, DKIM and DMARC policies on inbound email.

Creating Strong Passphrases
Multi-factor authentication (a combination of something that you know, something that you have or something that you are) is one of the most effective ways to protect against unauthorised access to valuable information and accounts. However, in cases where multi-factor authentication is not available, a strong passphrase can often be the only barrier between adversaries and your valuable information and accounts. Passphrases are most effective when they are long, complex, unpredictable and unique.

Windows Event Logging and Forwarding
A common theme identified by the Australian Cyber Security Centre (ACSC) while performing investigations is that organisations have insufficient visibility of activity occurring on their workstations and servers. Good visibility of what is happening in an organisation’s environment is essential for conducting an effective investigation. It also aids incident response efforts by providing critical insights into the events relating to a cyber security incident and reduces the overall cost of responding to them.
Hardening Microsoft Windows 8.1 Workstations
Workstations are often targeted by an adversary using malicious websites, emails or removable media in an attempt to extract sensitive information. Hardening workstations is an important part of reducing this risk. This document provides recommendations on hardening workstations using Enterprise editions of Microsoft Windows 8.1. Before implementing recommendations in this document, thorough testing should be undertaken to ensure the potential for unintended negative impacts on business processes is reduced as much as possible.
Essential Eight Explained
The Strategies to Mitigate Cyber Security Incidents is a prioritised list of mitigation strategies to assist organisations in protecting their systems against a range of adversaries. The mitigation strategies can be customised based on each organisation’s risk profile and the adversaries they are most concerned about.

The Essential Eight Maturity Model provides advice on how to implement the Essential Eight in a phased approach. It also assists organisations in self-assessing the maturity of their implementation.
Web Conferencing Security
Web conferencing solutions (also commonly referred to as online collaboration tools) often provide audio/video conferencing, real-time chat, desktop sharing and file transfer capabilities. As we increasingly use web conferencing to keep in touch while working from home, it is important to ensure that this is done securely without introducing unnecessary privacy, security and legal risks. This document provides guidance on both how to select a web conferencing solution and how to use it securely.
Implementing Application Control
Application control is one of the most effective mitigation strategies in ensuring the security of systems. As such, application control forms part of the Essential Eight from the Strategies to Mitigate Cyber Security Incidents.

This document has been developed to discuss approaches that can be applied by organisations to secure systems against malicious macros while balancing both their business and security requirements.
Preparing for and Responding to Denial-of-Service Attacks
Although organisations cannot avoid being targeted by denial-of-service attacks, there are a number of measures that organisations can implement to prepare for and potentially reduce the impact if targeted. Preparing for denial-of-service attacks before they occur is by far the best strategy, it is very difficult to respond once they begin and efforts at this stage are unlikely to be effective.
End of Support for Microsoft Windows 7
On 14 January 2020, Microsoft ended support for Microsoft Windows 7. As such, organisations no longer receive patches for security vulnerabilities identified in this product. Subsequently, adversaries may use these unpatched security vulnerabilities to target Microsoft Windows 7 workstations.
