how much does ccna certification cost.Take, for example, a forensic investigation of an Apple macOS device, when it may be necessary to collect hard evidence related to everything that happened on that device. If the endpoint host is only being monitored on a daily basis, it is not possible to examine and collect information about the host and user in question in the same way as in a forensic investigation. For example, for the same macOS device, a network administrator might use a top-down approach when examining files, starting with the root directory and then examining the user directory where a lot of evidence remains.Take another example of dumping all account information within the system. A macOS device would use a SQLite database to store accounts used within the system. This includes information such as email addresses, social media usernames, and content descriptions.Within Windows, the event logging service captures and stores events. This keeps events from different sources in an event log and contains information in chronological order. However, the type of data stored in the event log depends on the system configuration and application settings. The Windows event log can provide a large amount of data to investigators. Some of the content recorded in the event log (for example, event IDs and event categories) can assist network security personnel in obtaining information related to specific events. The Windows Event Logging service can be configured to store precise information about numerous objects within the system. Almost any system resource can be considered an object, so that network security personnel can detect any unauthorized requests for access to resources.In general, within the Security Operations Center (SOC), the network administrator's job is to monitor the logs sent from the endpoint systems to the Security Information Management (SIM) system and the Security Event Management (SEM) system (also called the SIEM system). As mentioned earlier, Spkmk is a SIEM system.The SIM system is primarily equipped to digest large amounts of log data, allowing network administrators to easily make sense of the logs collected from448 Chapter 11 Network and Host Insight Technologiesthe data for searching. The function of the SEM system is to consolidate and correlate large amounts of event data so that network security personnel or network administrators can prioritize and respond appropriately to events. Many SIEM vendors tend to "do it right" with one of their SIM or SEM systems, although their products can provide both event and information management capabilities. SIEM solutions can capture logs from a variety of common host security products, as follows.Personal firewalls.Intrusion detection/prevention systems. Anti-virus or anti-malware software.Web security logs are captured from Web security appliances. Capturing email security logs from an email security appliance. Logs captured from an advanced malware protection system. There are many other host security features, such as data loss prevention and VPN clients. Let's say that Cisco.
