![]() We recommend using the GNU Privacy Guard (GPG), an Open Source OpenPGP-compatible encryption system. If your computer is behind on updates there is a chance you could get infected with a copy-cat virus, but even then it is unlikely unless you are still running Windows XP or earlier.Encryption helps protect your files during inter-host file transfers that use protocols that are not already encrypted-for example, when using ftp or when using shiftc without the -secure option. It has a light system footprint however its memory usage is irrelevant because Windows cannot run properly without it. This process is safe and essential to the function of Windows. Overall lsass.xe is a default startup process which controls log on security. This is why it is important to always keep your system updated. Microsoft has long since patched the vulnerability that allowed the virus to infect Windows. If you find your computer is infected this virus is removable using the Microsoft Malware Removal tool.įortunately, the copycat “isass.exe” virus hasn’t been seen in a few years. This virus will log every keystroke typed, and particular go after account usernames, passwords, credit card numbers, and other sensitive data that can be used for fraudulent financial gain. The purpose of the worm is to covertly infect your system and begin harvesting data. This “isass.exe” is a trojan virus known as the Sasser worm. If you find the process starts with a capital “i” instead of a lower case “L” then your system is likely infected. Predominantly, the malicious process is named isass.exe (Isass.exe = bad) which looks similar to Lsass.exe (lsass.exe = good). However a copy-cat virus has been known to infect systems. On a security note, this process is safe. This manages and starts the ISAKMP/Oakley (IKE) and the IP security driver in Windows Server. ![]() This service should not be disabled.Īlso handled by lsass.exe is the local IPSEC Policy. Disabling this service will prevent other services in the system from being notified when SAM is ready, which may in turn cause those services to fail to start correctly. The startup of this service signals other services that the Security Accounts Manager (SAM) is ready to accept requests.The service stores and uses long lived keys in a secure process complying with Common Criteria requirements. The service provides key process isolation to private keys and associated cryptographic operations as required by the Common Criteria. ![]() The CNG key isolation is hosted in the LSA process.If this service is stopped or disabled, application will be unable to access encrypted files. Provides the core file encryption technology used to store encrypted files on NTFS file system volumes.Other processes that the user initiates inherit this token.Ī look at lsass.exe in process explorer reveals it handles 3 primary authentication services in Windows: When authentication is successful, lsass.exe generates a user access token, which is used to launch the initial shell. The process is performed by using authentication packages such as the default msgina.dll. Known as the local security authentication server, this file generates the process responsible for authenticating users in the WinLogon service. ![]()
