PTE Re-tell Lecture 真实讲座练习题: 网络安全

在PTE中,无论是Summarise Spoken Text 还是 Re-tell Lecture的考题大都是从真实的讲座或者演讲中截取的,中间经常经常夹杂很多不同的环境音.很多同学都反映有时未必是听不懂,而是听不到. 鉴于此,墨尔本文波雅思PTE专门为大家总结了真实讲座的PTE练习音频,相比新闻音频来说,整体更加接近PTE考试的真题,内容方面,我们也会为大家提供考试中存在的近似题,最近我们会持续更新,敬请期待!






And so what I thought I would talk to you about today is you’re looking at new trends and changing aspects and factors in international security, what I thought I would talk to you about were two trends that I think are changing. I think they’re changing geopolitics and geostrategy as we know it. One’s a trend of growth and one’s a trend of decay. And I think it bears critically on the major thing that is happening in all of our lives, the advent of the Internet, connectivity on line, life and cyberspace. Again, in my view, which is changing everything. I think there are three key aspects to life in cyberspace. And, and, the key aspects are technology, policy and strategy. And I think there are, there’s one big question in each of those areas. The key question in technology is, how do we construct systems that we can trust from components that we can’t? The key question in policy is, what would be the role of government in our lives in cyberspace? And what would be the role of government when it comes to cybersecurity? And the key to strategic question, I think we’re facing and we’re facing it squarely today is how will we maintain the openness of the Internet given it’s permeation of life online? So, when you talk about the threats people ask me, what is the greater threat? I’ve spent a lot of time on cyber security, when I was in Homeland Security, what keeps you up at night? That sort of thing I think the greatest threat from a cyber-security perspective by far, by far, by far. She said by far is unpatched vulnerabilities. That’s the biggest threat, unpatched vulnerabilities. There are bad things out, out there that are happening and by and large we’re not doing too much about them. You know, so, a lot of people like to entertain themselves where, you know, is the threat from the Far East more significant than the threat coming out of Central Asia? More significant from the threat coming out of other organized criminal networks around the world? That’s not particularly interesting to me. What’s really interesting is our, is social inertia in the face of an obvious requirement to act, an obvious ability to act, and an equally obvious inability to act. That’s kind of a real puzzling question to me. So I don’t and I don’t know why that’s happened.Powered by Hackadelic Sliding Notes 1.6.5
