Decryption is required to inspect TLS-encrypted traffic, allowing security tools (such as firewalls or intrusion prevention systems) to analyze the contents of the traffic for threats that would otherwise remain hidden within encrypted sessions.

page 211 "Consolidating servers within trust levels: Organizations often consolidate servers within the same trust level into a single virtual computing environment: ... ... ... This virtual systems capability enables a single physical device to be used to simultaneously meet the unique requirements of multiple VMs or groups of VMs. Control and protection of inter-host traffic with physical network security appliances that are properly positioned and configured is the primary security focus."

A botnet is a network of computers or devices that are infected by malware and controlled by a malicious actor, known as the botmaster or bot-herder. The botmaster uses a command and control (C2) server or channel to send instructions to the bots and receive information from them. The C2 communication is essential for the botmaster to maintain control over the botnet and use it for various malicious purposes, such as launching distributed denial-of-service (DDoS) attacks, stealing data, sending spam, or mining cryptocurrency. Therefore, the key to “taking down” a botnet is to prevent the bots from communicating with the C2 server or channel. This can be done by disrupting, blocking, or hijacking the C2 communication, which can render the botnet ineffective, unstable, or inaccessible. For example, security researchers or law enforcement agencies can use techniques such as sinkholing, domain name system (DNS) poisoning, or domain seizure to redirect the bot traffic to a benign server or a dead end, cutting off the connection between the bots and the botmaster. Alternatively, they can use techniques such as reverse engineering, decryption, or impersonation to infiltrate the C2 server or channel and take over the botnet, either to disable it, monitor it, or use it for good purposes. References:

SOAR (Security Orchestration, Automation, and Response) differs from SIEM by adding automated incident response and workflow orchestration to the detection and alerting capabilities found in SIEM. This enables faster and more efficient handling of security incidents.

SOAR stands for security orchestration, automation and response. It is a software solution that enables security teams to integrate and coordinate separate tools into streamlined threat response workflows. SOAR systems allow for accelerated incident response through the execution of standardized and automated playbooks that work upon inputs from security technology and other data flows. SOAR systems can also help ensure consistency, reduce human errors, and improve efficiency and scalability of security operations. References:

In anti-malware, a false positive incorrectly identifies a legitimate file or application as malware. A false negative incorrectly identifies malware as a legitimate file or application. In intrusion detection, a false positive incorrectly identifies legitimate traffic as a threat, and a false negative incorrectly identifies a threat as legitimate traffic.

MITRE is a not-for-profit organization that operates research and development centers sponsored by the federal government. MITRE maintains the Common Vulnerabilities and Exposures (CVE) catalog, which is a dictionary of common names for publicly known cybersecurity vulnerabilities. CVE’s common identifiers, called CVE Identifiers, make it easier to share data across separate network security databases and tools, and provide a baseline for evaluating the coverage of an organization’s security tools12. References:

Least privileges access control is the capability of a Zero Trust network security architecture that leverages the combination of application, user, and content identification to prevent unauthorized access. Least privileges access control means that users and devices are only granted the permissions they need to perform their tasks, and nothing more. This helps reduce the attack surface and makes it more difficult for attackers to gain access to sensitive data or resources. Least privileges access control is based on the principle of Zero Trust, which assumes that there are attackers both within and outside of the network, so no users or devices should be automatically trusted. Zero Trust verifies user identity and privileges as well as device identity and security, and requires end-to-end encryption. Least privileges access control also involves careful management of user permissions and network segmentation, which limit the amount of information and length of time people can access something, and contain the damage if someone does get unauthorized access. References: What Is Zero Trust Architecture? | Microsoft Security, Zero Trust security | What is a Zero Trust network? | Cloudflare, What is Zero Trust Architecture? | SANS Institute, What Is a Zero Trust Architecture? | Zscaler, What is Zero Trust Architecture (ZTA)? - CrowdStrike.

Forensics in a Security Operations process refers to collecting raw data needed to complete the detailed analysis of an investigation. Forensic analysis is a crucial step in identifying, investigating, and documenting the cause, course, and consequences of a security incident or violation. Forensic analysis involves various techniques and tools to extract, preserve, analyze, and present evidence in a structured and acceptable format. Forensic analysis can be used for legal compliance, auditing, incident response, and threat intelligence purposes. References:

Account discovery is a technique in the MITRE ATT&CK framework under the Discovery tactic. It involves adversaries attempting to identify user accounts on a system or network.

Credential access, lateral movement, and resource development are tactics — high-level objectives an attacker is trying to achieve.
