security_attributes用法 -回复
security_attributes用法-回复标题:深入理解与应用security_attributes在计算机编程中,security_attributes是一个重要的概念,特别是在Windows操作系统环境下。
它主要用于控制对象(如文件、进程、线程等)的安全特性,确保系统的安全性和稳定性。
以下是一步一步详细解析security_attributes的用法。
一、理解security_attributessecurity_attributes是一种结构体,它在Windows API中被广泛使用。
这个结构体包含了三个主要的成员:nLength、bInheritHandle和lpSecurityDescriptor。
1. nLength:这是一个整型变量,用于存储security_attributes结构体的大小。
这是为了确保API函数能够正确地处理这个结构体。
2. bInheritHandle:这是一个布尔型变量,用于决定是否允许子进程继承这个句柄。
如果设置为TRUE,那么子进程就可以继承这个句柄;如果设置为FALSE,那么子进程就不能继承这个句柄。
3. lpSecurityDescriptor:这是一个指向SECURITY_DESCRIPTOR结构体的指针。
SECURITY_DESCRIPTOR结构体定义了对象的安全特性,包括所有者、组、访问控制列表(ACL)和系统访问控制列表(SACL)。
二、创建security_attributes在使用security_attributes之前,首先需要创建一个security_attributes 结构体。
以下是一个简单的示例:c++SECURITY_ATTRIBUTES sa;sa.nLength = sizeof(SECURITY_ATTRIBUTES);sa.bInheritHandle = TRUE; 允许子进程继承句柄sa.lpSecurityDescriptor = NULL; 使用默认的安全描述符在这个示例中,我们首先创建了一个security_attributes结构体,并设置了它的nLength成员为sizeof(SECURITY_ATTRIBUTES)。

HP Data Protector A.06.11 disasterrecovery support for Microsoft Windows7 and Windows Server 2008 R2Technical white paperTable of contentsIntroduction (2)Installation (2)Preparing for Disaster Recovery (2)Prerequisites (2)Limitations (3)Related documentation (4)2Introduction This white paper describes specific prerequisites and steps needed for a successful Enhanced Automated Disaster Recovery (EADR) and One Button Disaster Recovery (OBDR) of Microsoft Windows 7 and Window Server 2008 R2 systems using Data Protector A.06.11. Additionally, limitations which you need to be aware of are described. For general disaster recovery preparation and procedures, see the HP Data Protector A.06.11 Disaster Recovery Guide . In this white paper, only the specifics applicable to Microsoft Windows 7 and Windows Server 2008 R2 are described. Note In the HP Data Protector A.06.11 Disaster Recovery Guide , all specifics which are described for Microsoft Windows Vista and Windows Server 2008, apply also to Windows 7 and Windows Server 2008 R2 and are not separately described in this white paper. Installation The market release version of Data Protector A.06.11 does not support EADR or OBDR for Windows 7 and Windows Server 2008 R2. To enable support for these two versions of the Windows operating system, install this patch on the target systems (backup system and the system on which you will create the disaster recovery ISO image). Before you install this patch, check the General Release Patches installation instructions and prerequisites. Preparing for Disaster Recovery Follow the EADR and OBDR procedures for Windows Vista and Windows Server 2008, as described in the HP Data Protector A.06.11 Disaster Recovery Guide . Additional Windows 7 and Windows Server 2008 R2 prerequisites and steps are listed below.Prerequisites Install Windows Automated Installation Kit (WAIK) 2.0 on the system on which you will createan ISO image. Older versions of WAIK (1.1) are not supported. The system reserved volume (the volume from which the Windows operating system boots) must have a drive letter assigned or at least it should be mounted to an NTFS directory. Note Backup of unmounted volumes is not supported in Data Protector 6.11 and they are not displayed by the Data Protector GUI.Perform a full backup of the client system. The backup must include the:CONFIGURATION object System reserved volume (a new requirement for Windows 7 and Windows Server 2008 R2) For how to perform a full backup of the client system, se e the online Help index: “backup, Windows specific” and “backup, configuration”.All backups must be performed with the following filesystem backup options selected:Detect NTFS hardlinksUse Shadow CopyThe option Allow fallback must be cleared.See the selected options in the figure:Due to a Microsoft limitation it is not possible to consistently back up a mounted virtual hard disk (VHD) volumes. Therefore, you should unmount all VHD volumes of a VHD file before backup to enable successful restore afterwards. Their corresponding VHD files are then backed up as part of their parent volume backup.If you accidentally leave the VHD volumes mounted and you back them up as all other volumes, you need to perform additional manual steps during restore of the VHD files:1.Create a dummy VHD file of equal or greater size of the original file.2.Re-create VHD volumes, matching the size and structure of the original VHD file.3.Start a manual filesystem restore to restore data into the previously created VHD volumes.e the same object version as was included in the full client backup.During restore, Minor errors are reported. On the other hand, you can avoid this behavior by manually editing the SRD file prior to performing disaster recovery. Remove all references to VHD volumes from the SRD file. In this case, you must identify the drive letters that represent the VHD volumes.LimitationsThe Data Protector A.06.11 original GUI does not support disaster recovery options onWindows 7 and Windows Server 2008 R2 clients because their identification string in the34cell_info file is higher than 6.0. All disaster recovery options in the GUI are therefore unavailable for selection.Use one of the following workarounds to enable the disaster recovery options: Use the Data Protector Java GUIinstead (for EADR). Temporarily modify the cell_info file to enable the options in the original GUI. For example, change the parameter -os "microsoft i386 wNT-6.1-W" to -os "microsoft i386 wNT-6.0-W". Use the free Windows Enabler tool, which can arbitrarily enable or disable the GUIoptions. One Button Disaster Recovery (OBDR) functionality is missing in the Data Protector Java GUI. Ifyou want to use the OBDR options in the GUI, use the original Data Protector GUI. VHD volumes cannot be restored by the disaster recovery procedure. If they are backed up as files during the backup of their parent volumes, they can be mounted following the disaster recovery procedure. Alternatively, you can recreate them anew and restore the data from the corresponding backupby using the recovered version of the Data Protector.Cluster shared volumes are not supported. The database is not restored for Active Directory – this is a known Disk Agent issue that was resolved by the original (Data Protector A.06.11) disaster recovery module (DRM), as the original DRM automatically restored part of the missing data. This functionality is still available for the module that is released as a patch, but it is no longer enabled by default. You must manually enable it during the recovery process by using the option Restore DAT [Pre].

北京联通FDD-LTE案例分析报告--安全模式失败导致E-RAB建立失败案例--security Mode Failure
北京联通FDD-LTE案例分析报告--安全模式失败导致E-RAB建立失败案例security Mode Failure事件:故障描述:在后台在进行信令跟踪中对UU,X2,S1进行提取,在该站点FBJ900111系统信令跟踪过程中出现初始建立失败,eNodeB向MME发送原因值。
RRC_SECUR_MODE_FAIL的信令条件,UE在向eNodeB的信令里面出现radio Network –security Mode Failure-r8,导致S1_INITIAL_CONTEXT_SETUP_FAIL失败。
故障分析:MME向eNB发送initial Context Setup Request消息,请求建立初始的UE上下文,包含E-RAB上下文、安全密钥、切换限制列表、UE无线性能以及UE安全性能等等。
初始建立的正常流程:请求建立初始正常流程图1本事件案例事件流程图2对网络中的问题分析,手机在接入以后,基站向MME发送了初始的消息上去,等待近6S的时间,MME收到以后进行了鉴权和加密的请求,在进行鉴权请求的同时,也在NAS上进行安全模式的建立,手机回应时失败(RRC),导致在RRC_SECUR_MODE_FAIL,UE直接失败,eNodeB直接进行了释放,S1AP_INITIAL_CONTEXT_SETUP_FAIL导致的接入失败。
以下几种原因易导致这种情况:1)初始消息未被基站正确接收:基站对在接入时收到的信息,针对这个信息进行发送UE的安全模式出错而有异常,因此安全模式出错上的问题。
2)RRC安全模式配置错误:安全模式关系配置错误会导致接入请求“RRC_SECUR_MODE_FAIL”无法发送,可能导致本案例里面无该现象。
3)设备故障:由于基站内部状态机设计存在缺陷,本案例里面的无该现象。
这种情况,一般可以采用重新启动基站的方法暂时消除。
具体排查过程如下:1:RRC上安全模式配置,看网络是否安全模式无问题情况;2:怀疑设备问题,重启设备,复测问题依旧;3:怀疑UE问题或者配置错误导致。

第8章网络安全技术与应用8.3操作系统安全设置操作系统是Web服务器的基础。
虽然操作系统本身在不断完善,对攻击的抵抗能力也日益提高,但是要提供完整的系统安全保证,仍然有许多安全配置和管理工作要做。
下面以Windows Server 2008为例,按照Web服务器的安全需要,介绍操作系统的安全措施。
8.3.1 系统服务包和安全补丁操作系统的漏洞和缺陷往往给攻击者大开方便之门,解决这个问题很简单,管理员应及时查询、下载和安装安全补丁,堵住漏洞。
微软提供的安全补丁有两类:服务包(Service Pack)和热补丁(Hot fixes)。
服务包已经通过回归测试,能够保证安全安装。
每一个Windows的服务包都包含着在此之前所有的安全补丁。
微软建议用户及时安装服务包的最新版。
安装服务包时,应仔细阅读其自带的Readme文件并查找已经发现的问题,最好先安装一个测试系统,进行试验性安装。
安全热补丁的发布更及时,只是没有经过回归测试。
微软通过其安全公告服务来发布安全公告,访问站点/china/security/bulletins/notify.asp可以获得关于修补安全漏洞的最新信息,及时下载并安装安全补丁。
在安装之前,应仔细评价每一个补丁,以确定是否应立即安装还是等待更完整的测试之后再使用。
在Web服务器上正式使用热补丁之前,最好在测试系统上对其进行测试。
微软提供的微软基准安全分析器(Microsoft Baseline Security Analyzer,MBSA)2.1支持Windows Server 2008 R2、Windows 7、Windows Server 2008、Windows Server 2003、Windows Vista、Windows XP操作系统和组件的漏洞评估检查。
改进了对SQL Server 2005漏洞评估检查的支持。
这些服务包和补丁的确可以消除系统中的一些弱点。
但是,不应当假定使用这些补丁就足以让自己的系统处于安全状态。
