Securing software with automated functional diversity

计算机安全对于大多数计算机用户来说仍然是一个持续的挑战。 现有的技术，如网络防火墙、病毒扫描程序和自动软件更新，可以抵御许多攻击。 尽管如此，由于管理错误、用户错误和未修补的软件漏洞，几乎每台连接到互联网的计算机都有可能随时受到损害。 由于电脑保安并无“银弹”，这种情况在可见的将来仍会持续。因此，如果我们希望确保互联网的安全，我们需要制定防御策略，以容忍我们的计算机系统和与它们一起工作的人类的缺陷。

Computer security remains a ongoing challenge for most computer users. Existing technologies such as network firewalls, virus scanners, and automated software updates defend against many attacks. Despite this, virtually every computer connected to the Internet has the potential to be compromised at any time due to administrative error, user mistakes, and unpatched software vulnerabilities. As there is no "silver bullet" for computer security, this situation will continue for the foreseeable future. Thus, if we wish to secure the Internet, we need to develop defense strategies that can tolerate imperfections in our computer systems and in the humans who work with them.
