Remote Access Tools (RAT) are malicious software that allow an attacker to remotely access and control a compromised host, often without the user’s knowledge or consent. RATs can be used to perform various malicious activities, such as stealing data, installing backdoors, executing commands, spying on the user, or spreading to other hosts. One of the main objectives of RATs is to maintain and expand control over the target network, by evading detection, hiding their presence, and creating persistence mechanisms. 

Anonymous proxies are servers that act as intermediaries between the user and the internet, hiding the user’s real IP address and allowing them to bypass network restrictions and access unauthorized websites. The best way to prevent users from visiting unauthorized websites using anonymous proxies is to block the IP address of known anonymous proxies on the firewall or router. This will prevent the user from establishing a connection with the proxy server and accessing the blocked content. Removing the anonymity from the proxy, analyzing IP traffic for proxy requests, or disabling the proxy server on the firewall are not effective ways to prevent future occurrences, as they do not address the root cause of the problem or require more resources and time to implement. References: The 17 Best Proxy Sites to Help You Browse Anonymously; Buy HTTP proxies and Socks5 | Anonymous Proxies; The Best Free Proxy Server List: Tested & Working!

The factors that must be considered when classifying information and supporting assets for risk management, legal discovery, and compliance are data stewardship roles, data handling and storage standards, and data lifecycle requirements. Data stewardship roles are the roles and responsibilities of the individuals or entities who are accountable for the creation, maintenance, protection, and disposal of the information and supporting assets. Data stewardship roles include data owners, data custodians, data users, and data stewards. Data handling and storage standards are the policies, procedures, and guidelines that define how the information and supporting assets should be handled and stored, based on their classification level, sensitivity, and value. Data handling and storage standards include data labeling, data encryption, data backup, data retention, and data disposal. Data lifecycle requirements are the requirements that specify the stages and processes that the information and supporting assets should go through, from their creation to their destruction. Data lifecycle requirements include data collection, data processing, data analysis, data sharing, data archiving, and data deletion. System owner roles and responsibilities, data handling standards, storage and secure development lifecycle requirements are not the factors that must be considered when classifying information and supporting assets for risk management, legal discovery, and compliance, although they may be related or relevant concepts. System owner roles and responsibilities are the roles and responsibilities of the individuals or entities who are accountable for the operation, performance, and security of the system that hosts or processes the information and supporting assets. System owner roles and responsibilities include system authorization, system configuration, system monitoring, and system maintenance. Data handling standards are the policies, procedures, and guidelines that define how the information should be handled, but not how the supporting assets should be stored. Data handling standards are a subset of data handling and storage standards. Storage and secure development lifecycle requirements are the requirements that specify the stages and processes that the storage and development systems should go through, from their inception to their decommissioning. Storage and secure development lifecycle requirements include storage design, storage implementation, storage testing, storage deployment, storage operation, storage maintenance, and storage disposal. Compliance office roles and responsibilities, classified material handling standards, storage system lifecycle requirements are not the factors that must be considered when classifying information and supporting assets for risk management, legal discovery, and compliance, although they may be related or relevant concepts. Compliance office roles and responsibilities are the roles and responsibilities of the individuals or entities who are accountable for ensuring that the organization complies with the applicable laws, regulations, standards, and policies. Compliance office roles and responsibilities include compliance planning, compliance assessment, compliance reporting, and compliance improvement. Classified material handling standards are the policies, procedures, and guidelines that define how the information and supporting assets that are classified by the government or military should be handled and stored, based on their security level, such as top secret, secret, or confidential. Classified material handling standards are a subset of data handling and storage standards. Storage system lifecycle requirements are the requirements that specify the stages and processes that the storage system should go through, from its inception to its decommissioning. Storage system lifecycle requirements are a subset of storage and secure development lifecycle requirements. System authorization roles and responsibilities, cloud computing standards, lifecycle requirements are not the factors that must be considered when classifying information and supporting assets for risk management, legal discovery, and compliance, although they may be related or relevant concepts. System authorization roles and responsibilities are the roles and responsibilities of the individuals or entities who are accountable for granting or denying access to the system that hosts or processes the information and supporting assets. System authorization roles and responsibilities include system identification, system authentication, system authorization, and system auditing. Cloud computing standards are the standards that define the requirements, specifications, and best practices for the delivery of computing services over the internet, such as infrastructure as a service (IaaS), platform as a service (PaaS), or software as a service (SaaS). Cloud computing standards include cloud service level agreements (SLAs), cloud interoperability, cloud portability, and cloud security. Lifecycle requirements are the requirements that specify the stages and processes that the information and supporting assets should go through, from their creation to their destruction. Lifecycle requirements are the same as data lifecycle requirements. 

 The discovery phase of a vulnerability assessment is the process of identifying and enumerating the hosts, services, and applications that are in scope of the assessment. This phase involves techniques such as network scanning, port scanning, service scanning, and banner grabbing. If one third of the hosts that were in scope are missing from the report, it means that the discovery phase was not performed properly or completely, and some hosts were not detected or included in the assessment. The enumeration, reporting, and detection phases are not likely to cause this error, as they depend on the results of the discovery phase. References: CISSP All-in-One Exam Guide, Eighth Edition, Chapter 7: Security Assessment and Testing, page 857; Official (ISC)2 Guide to the CISSP CBK, Fifth Edition, Chapter 6: Security Assessment and Testing, page 794.
