Essential Eight to ISM Mapping
This document provides a mapping between the Essential Eight Maturity Model and the security controls within the Australian Government Information Security Manual (ISM). This mapping represents the minimum security controls organisations must implement to meet the intent of the Essential Eight.
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.

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.
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.
