We will also provide greater protection upstream. The government will help to develop a national protective domain name service or PDNS. When someone tries to connect to a domain which is known to be malicious, the PDNS can stop the
connection before the threat reaches the user. This will potentially help to reduce exposure to fishing, scams, malware, and other cyber threats. Third, we have to act the speed of the threat. If AI allows attackers to identify vulnerabilities and
conduct attacks more quickly, then the defenders will have to use AI too. Government will progressively deploy AI across our national cyber defense operations including within NC3 and the government cyber security operations center. We will also work with industry
and technology partners to speed up the adoption of AI enabled cyber defense capabilities. This will be done across our critical sectors. We already have capabilities being developed across government. The CSA has developed AI tools to automate discovery and
mapping of exposed assets and vulnerabilities and to assist cyber security specialists in testing complex vulnerabilities in web applications. GVtech uses AI agents to accelerate the discovery of vulnerabilities and security testing. We will take a pragmatic approach. We do
not need to develop our own AI models for every use case. What we really need is the capability to evaluate the best available models and to adapt them to our own needs. We will therefore invest in AI harness
engineering which will give us the flexibility to choose between AI models and to securely integrate the best available ones with the tools, the data and the workflows which cyber defenders need. Even with our shift to a more proactive
defense, it's not going to be possible to prevent all attacks. That makes cooperation even more important. We should be realistic about the environment we are in. There will be more strategic competition particularly over critical technologies like AI. Countries
will act to safeguard their national interest. Singapore will do the same. But it is dangerous if every country's response to strategic competition is to just build inward and to act independently. This will break up the digital ecosystem that
we all depend on.
