cisco certification tracker.(II and issue a message. As described in NIST SP 800-6lr2, an event (event) is anything observable that occurs in a system or network, and a security incident (security incident) is a violation of a unit's security regime. Security analysts in the Security Operations Center have the important job of determining when an event constitutes a security incident. An eventlog (or simply log) is an official record of an event and contains information about the event itself (e.g., timestamps, IP addresses, error codes, etc.). Event management refers to the controls implemented at the administrative level, physical level, and technical level to properly collect, store, and analyze events. Event management plays an important role in information security because network security personnel detect and troubleshoot attacks in real time based on event logs, respond quickly to security events, and generate statistical and trending reports of security information. If the unit lacks information related to historical events and logs, bei I" will reduce its ability to troubleshoot security incidents and analyze root causes.5.3 Security Event and Log Management 249 Another important function of monitoring and event management is compliance. Many compliance frameworks (e.g., ISO and PCI250 Chapter 5 Introduction to Security Operations and Maintenance ManagementDSS) require the implementation of log management controls and specify specific implementation methods.5.3.1 Log Collection, Analysis, and DispositionLog collection is one of the fundamental tasks of incident management. In fact, many systems in the IT infrastructure are capable of generating and bottle-pointing logs to remote systems that store them. The top priority for log storage is to maintain the confidentiality and integrity of the logs. Because logs can contain sensitive information, it is important to ensure their confidentiality. In some cases, logs can also serve as an important reference for presenting physical evidence orresponse to a security incident, so the integrity of the logs must also be ensured. The system used to store the logs needs to be protected from unauthorized access and the integrity of the logs should be maintained. Adequate storage space should be allocated to the system and logs should not be lost due to insufficient storage space. In general, the information collected through logs includes, but is not limited to, the following.User IDs. System behavior. Timestamps. Successful or unsuccessful access attempts. Configuration changes. Network address and protocol type.File access behavior. The format of the log messages they send varies from system to system. According to NIST SP800-92, security professionals should pay close attention to the following three types of logs. Logs generated by security software: This includes logs and alarm messages generated by the following software and devices.. Anti-virus/anti-malware gateways.
