The web server logs are records of the requests and responses that occur between a web server and a web client, such as a browser. The web server logs can show where the malware originated by indicating the source IP address, the destination URL, the date and time, the HTTP status code, the user agent, etc., of each request and response. The web server logs can help the incident response team to trace back the malicious website that infected the host with malware.

A tabletop exercise is a type of simulation exercise that involves discussing hypothetical scenarios and testing the incident response plan in a low-stress environment. A tabletop exercise can help an organization to improve its incident response process by identifying gaps, weaknesses, roles, responsibilities, communication channels, etc., and by evaluating the effectiveness and efficiency of the plan.

A geolocation policy is a policy that restricts access to data or resources based on the physical location of the user or device. A geolocation policy can be implemented using technologies such as IP address filtering, GPS tracking, VPN blocking, etc. A geolocation policy can help the company's legal department to ensure the documents cannot be accessed by individuals in high-risk countries by denying access requests from those countries.

Impossible travel time is a security metric that detects anomalous login attempts based on the time and distance between two locations. Impossible travel time can help prevent email account compromises by flagging login attempts that occur within a short time span from locations that are far apart, such as France and Brazil. Impossible travel time can indicate that an attacker has stolen or guessed the user's credentials and is trying to access their email account from another location.

Off boarding is a security practice that involves revoking access rights and privileges from employees who leave an organization or change their roles. Off boarding can help address the issue of successful logon attempts to access the departed executive's accounts by disabling or deleting their accounts, changing passwords, collecting devices, etc., as soon as they leave the organization.

A tabletop exercise is a type of simulation exercise that involves discussing hypothetical scenarios and testing the incident response plan in a low-stress environment. A tabletop exercise can help the CSO to validate the business's involvement in the incident response plan by involving key stakeholders, such as senior management, business units, legal department, etc., in the discussion and evaluation of the plan.

Segmentation is a security technique that divides a network into smaller subnetworks or segments based on criteria such as function, role, location, etc. Segmentation can help mitigate the risk of unauthorized access or data leakage by isolating different segments from each other and applying different security policies and controls to each segment. Segmentation can help the security manager to implement a mitigation while maintaining alerting capabilities by separating the smart generator from the internal file server and allowing only necessary communication between them.

The order of volatility is the order of how quickly data can be lost or changed in a system. The order of volatility is important for digital forensics and evidence collection, as it determines the priority and sequence of data preservation. The correct order of volatility from most to least volatile is cache, memory, temporary filesystems, disk, archival media. Cache is the fastest and most volatile type of memory that stores frequently used data. Memory is the main memory or RAM that stores data for active processes. Temporary filesystems are files that are created and deleted during normal system operations, such as swap files, print spool files, etc. Disk is the permanent storage device that stores data on magnetic or solid-state media. Archival media are devices that store data for long-term preservation, such as optical disks, tapes, etc.

The SIEM log shows that the user opened an email attachment named "Invoice.xlsx" and then executed a PowerShell script that downloaded and ran a malicious file from a remote server. This indicates that the attacker was able to bypass the application approve list by emailing a spreadsheet attachment with an embedded PowerShell in the file. This is a common technique used by malware authors to evade detection and deliver their payloads1.
