So, in this case, we are going to have to use some good filters, either in Event Viewer or in your preferred logging utility. Tracking both successes and failures of logons in an environment of any size is going to generate a large number of audit events in a very short period. After this is done, a number of events will be generated on the domain controllers any time a user logs on or off, both interactively or not. You may want to choose to audit other events as well. These settings are set in Computer Configuration > Policies > Windows Settings > Security Settings > Local Policies > Audit Policy, as shown. For me, step one for setting up a new Active Directory domain is to enable both success and failure of auditing account logon events, either in the Default Domain Policy or the Default Domain Controllers Policy. After you’ve established your standards for monitoring logon events, SEM is built to provide industry-specific audit logs as well as live security alerts.Step one in getting any real information is to enable auditing at the domain level. Once SolarWinds SEM is installed, you will be able to set your security audit log preferences to monitor a wide variety of security events-from logon events, to system events, to account management. If your server doesn’t have Active Directory deployed, these policies can also be configured at the local machine. To set the Windows audit policy, use Group Policy Object Editor or a similar application to define the default policy so it includes Success and Failure for audit process tracking. To configure Windows audit policy for SEM, you first need to modify the Windows audit policy using group policy at the domain controller and domain levels, so SEM can collect logs from your Windows system. SolarWinds Security Event Manager offers security log management designed to keep track of account logon events to help you identify activity that may signal an issue. How do I audit account logon events in Security Event Manager?.To record logon event data in a reportable format, the SIEM software in SEM is built to support security data log auditing, since performing regular audits can help you keep track of security activity and demonstrate compliance. An effective logon audit often requires a program that can monitor all relevant components in real time and pick up on patterns or data discrepancies that may signal a security issue. However, even the best-trained cybersecurity specialist may not always be able to detect unusual logon events with their own eyes. Users with greater access may be able to delete, modify, and even leak critical server data accidentally, or in the case with cyberattackers who gain these privileged user credentials through attacks like phishing, with malicious intent. Additionally, in many organizations there are certain privileged users granted greater access to sensitive data than others, so monitoring events for this user type is especially important. While most user logons signal ordinary use, some user activity can signal breaches of approved use. Why is auditing logon events important?Īuditing logon events should be a central strategy of your server security management protocol.If a logon event meets defined criteria, SEM is designed to be able to take immediate steps to protect the data and prevent additional user activity by disabling user accounts, logging off users, and blocking device IP addresses. Specifically, a security information and event management (SIEM) software like SolarWinds SEM is built to monitor logon events in real time, compiling data and correlating trends to flag any unusual logon or pattern of logons and alert the central IT controller. Using a security management software can help isolate user activity log data and to observe activity relevant to specific security concerns, such as logon or logoff instances. The starting point to auditing logon events is collecting the logon and logoff data, typically located in a directory service like Windows Active Directory (AD) where admins can configure security groups, manage privileged user information like logon credentials, and specify who can modify server data. A logon event audit consists of collecting and analyzing log data of user activity to create a report that highlights critical information about logon/logoff events.
