从信息技术安全的角度讨论威胁、暴露和脆弱性之间的区别。给出每一个例子(不仅仅是定义)。(~250字)威胁可以定义为可能对信息系统安全产生不利影响的事件的可能原因。对于一个组织的it安全来说，威胁可以通过利用系统密码的弱点进行未经授权的入侵。威胁评估必须进行，以确定保护系统免受一类威胁或特定威胁的最佳方法。为了开发针对假定威胁所指的攻击类别的有效对抗程序，进行了渗透测试。脆弱性可以定义为一个或多个威胁可以利用的安全系统或资产的弱点。如果系统密码对于全面的字典密钥攻击很弱，那么it系统的安全性可能会受到影响。

系统脆弱性评估必须持续进行。它将有助于安全管理人员认识到对安全的意料之外的威胁，这些威胁是需要解决的。这些还可能涉及社会方面，如用户的授权和身份验证策略(Perrin, 2009)。在信息技术系统中，暴露是一种条件，即使不是一般的弱点，但可以允许入侵者进行收集信息或隐藏此类行为的活动。例如，它可能是系统配置中的一个问题，或者是软件中的一个小故障，它允许访问攻击者可以用来渗透到系统中的设施或数据(CVE, 2013)。可以有效地进行暴露评估，以控制系统的脆弱性，并防范威胁。

From an I.T. security perspective discuss the differences between threat, exposure and vulnerability. Give an example of each one (not just a definition). (~250 Words)Threat can be defined as a probable reason for an occurrence that may have adverse effect on the information system security. For I.T. security of an organisation, threat can be unauthorised intrusion by exploiting the weakness of the system password. Threat evaluation must be done in order to decide the best methods for safeguarding the system against a class of threat, or specific threat. In order to develop efficient counter procedures against the categories of attacks signified by an assumed threat, penetration testing is done.Vulnerability could be defined as a weakness of the security system or asset which could be exploited by one or more threats. I.T. system security could be vulnerable if the system password is weak for comprehensive dictionary key attacks.

A system vulnerability assessment must be conducted on a continuous basis. It would help the security managers to recognise the unanticipated threats to the security that are necessary to be resolved. These could also involve social aspects like users’ authorization and authentication strategies (Perrin, 2009). Exposure in the I.T. system is a condition which even though not a general vulnerability, but could either permits an invader to do activities for gathering information or hiding such actions. For example, it could be an issue in system configuration or glitch in the software which permits access to facilities or data that an attacker can use to penetrate in the system (CVE, 2013). Exposure assessment can be effectively done to control vulnerability of the system and keep the threats away.
