一种移动存储设备管控的方法和装置 技术领域
本申请涉及数据信息安全防护技术领域,并且更具体地,涉及一种移动存储设备管控的方法和装置。
背景技术
工业控制系统所在网络属于一种内部网络,一般与互联网是物理或逻辑隔离的。病毒或恶意软件可以通过移动存储设备,如U盘、移动硬盘等,“摆渡”到内部网络并进行传播,给工控系统的信息安全管理控制带来了很大挑战。目前,部分工厂在主机上部署了杀毒软件,但由于不能保证杀毒软件的及时更新,处理病毒的有效性和及时性均无法保证。还有部分工厂允许有限的移动存储设备可以在内部使用,但也无法保证这些移动存储设备不被病毒或恶意软件感染。另外,即便移动存储设备经过定期查杀,仍然无法保证移动存储设备在使用过程中不被感染,进而无法保证移动存储设备在每次接入工控网络前处于安全状态。
因此,亟需一种保证访问工厂设备中的移动存储设备为安全移动存储设备的管控方法,从而提高工控系统信息和财产的安全性。
发明内容

图1示出了本申请实施例的移动存储设备管控的方法100的示意性流程图。方法可以由移动存储设备拦截器执行。方法100可以包括以下内容中的至少部分内容。
110,当移动存储设备拦截器检测到移动存储设备插入客户端设备时,获取该移动存储设备的信息,该移动存储设备的信息包括移动存储设备的标识信息和移动存储设备的第一文件信息,第一文件信息用于记录该移动存储设备当前的文件的属性信息。
在本申请实施例中,客户端设备可以为工控系统中的工程师站、操作员站,比如可以是具有人机交互接口(human machine interface,HMI)的计算机设备等。
在本申请实施例中,移动存储设备拦截器是一个软件,安装于上述客户端设备上。
具体地,当移动存储设备插入到客户端设备时,移动存储设备拦截器可以读取移动存储设备的信息以判断是否允许该移动存储设备访问客户端设备,访问客户端设备包括获取客户端设备上的数据或将移动存储设备的数据写入客户端设备等操作。其中,移动存储设备拦截器安装于客户端设备上。
在本申请实施例中,移动存储设备的信息包括移动存储设备的标识信息和移动存储设备的第一文件信息。其中,移动存储设备的标识信息可以为该移动存储设备的身份标识号(identification,ID),也就是该移动存储设备的序列号。移动存储设备的第一文件信息可以包括移动存储设备当前的文件的属性信息,其中,文件的属性信息例如可以是每个文件的创建或更新时间、文件总数、总文件的大小等信息,本申请对文件信息的具体内容不作限定。
一种实现方式中,移动存储设备的信息还可以包括移动存储设备的供应商、标签、卷等信息。
120,移动存储设备拦截器根据移动存储设备的信息和白名单管控该移动存储设备,其中,白名单包括通过安全扫描的安全移动存储设备的标识信息和安全移动存储设备的第二文件信息,第二文件信息用于记录安全移动存储设备通过安全扫描时的文件的属性信息。
在本申请实施例中,白名单指的是在白名单中的移动存储设备已经过安全扫描,并且经过安全扫描后该移动存储设备是安全移动存储设备。其中安全移动存储设备是指该移动存储设备中不存在病毒或恶意软件。
在一种实现方式中,当移动存储设备的标识信息不在白名单中,移动存储设备拦截器拒绝该移动存储设备对客户端设备的访问。也就是说,当移动存储设备的标识信息不在白名单时,该移动存储设备未经安全扫描,不能确认该移动存储设备是否被病毒或恶意软件感染,因此移动存储设备拦截器拒绝该移动存储设备访问客户端设备。
通过该实现方式,在移动存储设备访问客户端前,通过移动存储设备拦截器判断该移动存储设备是否在白名单内,当不在白名单内时,即不确定该移动存储设备是否感染病毒或恶意软件时,拒绝该移动存储设备的访问,使未经安全扫描的移动存储设备无法接入工厂网络。
在一种实现方式中,当移动存储设备的标识信息在白名单中,移动存储设备拦截器判断第一文件信息是否与该移动存储设备的标识信息对应的第二文件信息一致。其中,第二文件信息可以包括移动存储设备通过安全扫描时的文件的属性信息,文件的属性信息例如可以是通过安全扫描每个文件的扫描时间、文件总数、总文件的大小等信息。
需要说明的是,移动存储设备拦截器在判断第一文件信息与第二文件信息是否一致时,只是将第一文件信息和第二文件信息中相同类别的文件属性 信息进行对比,从而判断出第一文件信息与第二文件信息是否一致。例如,将第一文件信息中的文件总数与第二文件信息中的文件总数进行对比,或,将第一文件信息中的每个文件的创建或更新时间与第二文件信息中的每个文件的扫描时间进行对比,或,将第一文件信息中的总文件大小与第二文件信息中的总文件大小进行对比。
应理解,即使移动存储设备已经经过安全扫描也不能保证该移动存储设备在插入客户端设备之前不被感染,因此需要将移动存储设备当前的文件信息与移动存储设备经过安全扫描时的文件信息对比是否一致。
应理解,上述该移动存储设备的标识信息对应的第二文件信息是指,当该移动存储设备在白名单时,白名单中记录的该移动存储设备的文件信息,也就是移动存储设备经过安全扫描时的文件信息。
可能地,第一文件信息与移动存储设备的标识信息对应的第二文件信息一致,移动存储设备拦截器允许该移动存储设备对客户端设备的访问。即移动存储设备经过安全扫描后,插入客户端设备之前的这段时间,移动存储设备未经过文件篡改或侵入,仍然是安全移动存储设备,此时允许该移动存储设备对客户端设备的访问。
在一种实现方式中,允许移动存储设备对客户端设备的访问可以是激活该移动存储设备并连接到客户端设备的操作系统上。
可能地,第一文件信息与移动存储设备的标识信息对应的第二文件信息不一致,移动存储设备拦截器拒绝该移动存储设备对客户端设备的访问。即移动存储设备经过安全扫描后,插入客户端设备之前的这段时间,移动存储设备中的文件可能经过篡改或病毒侵入,不能确定该移动存储设备是否安全,因此拒绝该移动存储设备对客户端设备的访问。
通过上述方案,即使移动存储设备在白名单中,在移动存储设备访问客户端前,还要经过二次验证,判断该移动存储设备当前的文件信息与该移动存储设备经过安全扫描时的文件信息是否一致,再次确定移动存储设备是否安全,当不确定该移动存储设备是否安全时,移动存储设备无法进入工厂网络。
在一种实现方式中,第一文件信息与移动存储设备的标识信息对应的第二文件信息不一致时,移动存储设备拦截器向移动存储设备管理器发送第一指示信息,指示移动存储设备管理器将该移动存储设备的信息从白名单中删 除。
通过该实现方式,当移动存储设备当前的文件信息与该移动存储设备经过安全扫描时的文件信息不一致的情况下,将该移动存储设备的信息从白名单中删除,从而使该移动存储设备的安全身份失效,当该移动存储设备再次插入客户端设备时,移动存储设备拦截器拒绝该移动存储设备的访问。。
在一种实现方式中,在步骤110,移动存储设备拦截器获取移动存储设备的信息之前,首先在客户端上安装移动存储设备拦截器,并保证移动存储设备拦截器为开启状态。
在一种实现方式中,白名单是由移动存储设备管理器发送至客户端设备的,客户端设备可以将接收到的白名单保存至本地白名单中,以便移动存储设备拦截器的使用。
图2示出了本申请实施例的另一种移动存储设备管控的方法200的示意性流程图。方法200可以由反病毒扫描器执行。方法200可以包括以下内容中的至少部分内容。
210,反病毒扫描器对移动存储设备进行安全扫描。
在本申请实施例中,反病毒扫描器是一种集成多个杀毒引擎的组件或设备,当移动存储设备插在该组件或设备上时,杀毒引擎可以自动对该移动存储设备进行安全扫描。
在一种实现方式中,反病毒扫描器利用该多个杀毒引擎交叉扫描移动存储设备,当该移动存储设备未感染病毒或该移动存储设备感染的病毒被杀毒引擎杀死时,确定该移动存储设备通过安全扫描;当该移动存储设备感染的病毒未被杀毒引擎杀死时,确定该移动存储设备未通过安全扫描。
在一种实现方式中,当该移动存储设备感染的病毒未被杀毒引擎杀死时,意味着该病毒可能需要手动清理,可以向管理人员发出特定信号,例如红色光,使得管理人员及时清理。
在一种实现方式中,反病毒扫描器会连接至互联网,实时更新病毒特征库,生成相应的杀毒引擎,以便及时、有效地清理移动存储设备的病毒。
220,在该移动存储设备通过安全扫描后,反病毒扫描器将该移动存储设备的信息发送至移动存储设备管理器,移动存储设备的信息包括移动存储设备的标识信息和移动存储设备通过安全扫描时的文件信息。
其中,移动存储设备的信息用于将该移动存储设备的信息加入白名单。
需要说明的是,上述移动存储设备通过安全扫描时的文件信息与步骤120所述的第二文件信息是一样的,为了简洁,此处不再赘述。
上述步骤220中,防病毒扫描器对移动存储设备完成安全扫描后,仅将通过安全扫描的移动存储设备的信息发送至移动存储设备管理器,使得移动存储设备管理器直接将该移动存储设备的信息加入至白名单。而在另一种实现方式中,反病毒扫描器还可以将扫描结果与移动存储设备的信息一起发送给移动存储设备管理器,由移动存储设备管理器根据扫描结果判断是否将该移动存储设备的信息加入至白名单中。
应理解,本申请实施例的反病毒扫描器也可以称为防病毒扫描器,本申请对该设备或组件的名称不作限定。
由于反病毒扫描器与客户端设备相比是独立的设备或组件,且与工厂中客户端设备使用的网络是隔离的,通过该实现方式可以随时更新病毒库,避免反病毒扫描器与客户端为一体时,不能及时更新而导致某些新病毒进入工控系统的情况。
图3示出了本申请实施例的另一种移动存储设备管控的方法300的示意性流程图。方法300可以由移动存储设备管理器执行。方法300可以包括以下内容中的至少部分内容。
310,移动存储设备管理器接收反病毒扫描器发送的移动存储设备的信息,该移动存储设备的信息包括所述移动存储设备的标识信息和该移动存储设备通过安全扫描时的文件信息。
在本申请实施例中,移动存储设备管理器是一种运行在服务器上的程序,用于管理白名单,例如可以对白名单进行添加、删除或更新等操作。
在一种实现方式中,移动存储设备管理器还可以管理客户端设备中的移动存储设备拦截器,例如通过开启、停止或卸载管理移动存储设备拦截器。应理解,本申请实施例的移动存储设备管理器也可以称为移动存储设备管理平台,本申请对该程序的名称不作限定。
应理解,上述移动存储设备的信息与步骤220所述的移动存储设备的信息是一样的,为了简洁,此处不再赘述。
320,移动存储设备管理器将该移动存储设备的信息加入白名单。
在本申请实施例中,当移动存储设备管理器接收到反病毒扫描器发送的移动存储设备的信息时,可以对该移动存储设备进行注册,并将该移动存储 设备的信息存储在白名单中。
330,移动存储设备管理器向客户端设备发送该白名单。
在一种实现方式中,移动存储设备管理器可以定期同步更新白名单至客户端设备的本地白名单。
在一种实现方式中,客户端设备可以从移动存储设备管理器上定期或不定期地下载白名单,实现白名单的主动获取。
在一种实现方式中,移动存储设备管理器接收到移动存储设备拦截器发送的第一指示信息时,将该移动存储设备的信息从白名单中删除,从而使该移动存储设备的安全身份失效。
通过上述方案,移动存储设备管理器可以为通过安全扫描的移动存储设备自动创建白名单,无需人工维护,减少了人工管理的成本与工作量。
上述过程是移动存储设备通过安全扫描后自动被移动存储设备管理器加入到白名单中,还有一种可选的实施方式,工厂管理员可以向移动存储设备管理器中的白名单手动加入一个或多个移动存储设备的信息,即当工厂管理员认可该一个或多个移动存储设备的安全性并授权该一个或多个移动存储设备为安全移动存储设备。
图4示出了本申请实施例的移动存储设备拦截器400的示意性框图。该移动存储设备拦截器400可以是一个软件,安装于客户端设备上。该移动存储设备拦截器400可以执行上述本申请实施例的移动存储设备管控的方法100,该移动存储设备拦截器400可以为前述方法中的移动存储设备拦截器。
