Also. • Recipe 7-15 for configuring startup protection • Recipe 7-17 for creating a persistent IPSec policy • Microsoft TechNet: “Understanding IPSec Driver Startup Modes" (http:// www.microsoft.com/technet/prodtechnol/windowsserver2003/library/DepKit/ b0b6adaa-6b38-4952-b055-14559f46e561.mspx). driver modes to improve security. IPSec driver modes are established during computer startup and are adjusted using netsh. IPSec Driver modes are as follows: Startup The IPSec driver is loaded into this mode during Windows Server 2003 operat— ing system boot. There are three communication options within this mode. Event Source: IPSEC. Event Category: None. Event ID: 4292. Date: Time: User: N/A. Computer: COMPUTER_NAME. Description: The IPSec driver has entered Block mode. IPSec will discard all inbound and outbound TCP/IP network traffic that is not permitted by boot-time IPSec Policy exemptions. This issue occurs because some packets might be sent over the network before the IPSec driver has been initialized and before the IPSec policy has been processed. To resolve this issue, put the IPSec driver IPSec.sys into Block Mode during the computer startup process. When you do this, IPSec blocks. The IPsec driver, using the IP Filter List from the active IPsec policy, watches for outbound IP packets that must be secured and inbound IP packets that must be verified and decrypted. This security policy setting reports on the following activities of the IPsec driver: Startup and shutdown of IPsec services. Second, during the time between the start of the IPSec driver, but before the IPSec Policy agent service starts, network traffic can be both received and sent. Set the IPSec Driver Startup Mode to protect this period. “More on this later." Third, after the IPSec Policy Driver starts, but before it can apply the local-. A clue: Description: The IPSec driver has entered Block mode. IPSec will discard all inbound and outbound TCP/. IP network traffic that is not permitted by boot-time IPSec Policy exemptions. User Action: To restore full unsecured TCP/IP connectivity, disable the IPSec services, and the restart the computer. Event 4294 will occur once the IPSEC Service starts, about 8 seconds after the event for the Driver if the Service's startup type is Automatic. Event 4295 (Bypass) will occur if the Service is Disabled, regardless of the OperationMode registry setting. See ME254949, and the links to “Understanding IPSec Driver Startup Modes". Understanding How the IPSec driver operates. The IPSec driver operates in the following three modes: Computer startup mode: When the computer starts, the IPSec driver is loaded and the IPSec Policy Agent puts the IPSec driver in operational mode. In the Computer Startup mode, the IPSec driver can operate in any of.

Creating a Persistent Policy. Problem. You want to configure a persistent IPSec policy for a Windows. Internet Protocol security (IPSec) in the Microsoft® Windows® Server 2003 operating system protects networks from active and passive attacks by securing IP packets through the use of packet filtering, cryptography, and the enforcement of trusted communication. IPSec is useful in host-to-host, virtual private network (VPN),. What Is IPSec Startup Protection? To understand IPSec startup mode, think in terms of the three phases of startup. The. first stage is when the computer is booted, before the IPSec driver is loaded. (There's. no IPSec protection at this stage.) The second stage is after the driver is loaded but. before the IPSec service starts.
