Setting up a warm disaster recovery site with the same cloud provider in a different region can help to achieve a recovery time objective (RTO) of 12 hours while keeping the costs low. A warm disaster recovery site is a partially configured site that has some of the essential hardware and software components ready to be activated in case of a disaster. A warm site can provide faster recovery than a cold site, which has no preconfigured components, but lower costs than a hot site, which has fully configured and replicated components. Using the same cloud provider can help to simplify the migration and synchronization processes, while using a different region can help to avoid regional outages or disasters .

Server-side input validation is a solution that can prevent cross-site scripting (XSS) vulnerabilities by checking and filtering any user input that is sent to the server before rendering it on a web page. Server-side input validation can help to ensure that the user input conforms to the expected format, length and type, and does not contain any malicious characters or syntax that may alter the logic or behavior of the web page. Server-side input validation can also reject or sanitize any input that does not meet the validation criteria .

Using whole disk encryption is the best option to protect the data on the remote users' laptops. Whole disk encryption is a technique that encrypts all data on a hard disk drive, including the operating system, applications and files. Whole disk encryption can prevent unauthorized access to the data if the laptop is lost, stolen or compromised. Whole disk encryption can also protect the data from physical attacks, such as removing the hard disk and connecting it to another device .

Reporting this activity as a false positive, as the activity is legitimate, is the best way for the security analyst to respond. A false positive is a condition in which harmless traffic is classified as a potential network attack by a security monitoring tool. Ping requests are a common network diagnostic tool that can be used to test network connectivity issues. The technician who responded to potential network connectivity issues was performing a legitimate task and did not pose any threat to the accounting and human resources servers .

Stress testing is a software assessment method that tests how an application performs under peak times or extreme workloads. Stress testing can help to identify any performance issues, bottlenecks, errors or crashes that may occur when an application faces high demand or concurrent users. Stress testing can also help to determine the maximum capacity and scalability of an application .

Generating hashes for each file from the hard drive is the next action that the analyst should perform to ensure the data integrity of the evidence. Hashing is a technique that produces a unique and fixed-length value for a given input, such as a file or a message. Hashing can help to verify the data integrity of the evidence by comparing the hash values of the original and copied files. If the hash values match, then the evidence has not been altered or corrupted. If the hash values differ, then the evidence may have been tampered with or damaged .

A hypothesis is a statement that can be tested by threat hunters to establish a framework for threat assessment. A hypothesis is based on situational awareness and threat intelligence information, and describes a possible attack scenario that may affect the organization. A hypothesis can help to guide threat hunters in their investigation by providing a clear and specific question to answer, such as ''Is there any evidence of lateral movement within our network?'' or ''Are there any signs of data exfiltration from our servers?''.

Trusted firmware updates are a method by which security packages are delivered to the company's customers. Trusted firmware updates are digitally signed packages that contain software updates or patches for devices, such as routers, switches, or firewalls. Trusted firmware updates can help to ensure the authenticity and integrity of the packages by verifying the digital signature of the sender and preventing unauthorized or malicious modifications to the packages .

Implementing input validation is the best way to locate and prevent the issue of manipulation of the public-facing web form used by customers to order products. Input validation is a technique that checks and filters any user input that is sent to an application before processing it. Input validation can help to ensure that the user input conforms to the expected format, length and type, and does not contain any malicious characters or syntax that may alter the logic or behavior of the application. Input validation can also reject or sanitize any input that does not meet the validation criteria .

Automating the use of a hashing algorithm after verified users make changes to their data is an appropriate course of action to verify that a user's data is not altered without the user's consent. Hashing is a technique that produces a unique and fixed-length value for a given input, such as a file or a message. Hashing can help to verify the data integrity by comparing the hash values of the original and modified data. If the hash values match, then the data has not been altered without the user's consent. If the hash values differ, then the data may have been tampered with or corrupted .
