A legal hold is a process that requires an organization to preserve electronically stored information and paper documents that are relevant to a pending or anticipated litigation or investigation. It suspends the normal retention and destruction policies and procedures for such information and documents until the legal hold is lifted or released. 

Wireless jamming is a way for an attacker to disrupt a wireless network and create a denial of ser-vice situation by decreasing the signal-to-noise ratio at the receiving device. The attacker would need to be relatively close to the wireless network to overwhelm the good signal. The other options are not likely to cause a wireless network outage for users near the parking lot.

An intrusion prevention system (IPS) is the best solution to implement on the company’s network to detect and prevent suspicious attempts to access company resources. An IPS is a network security technology that continuously monitors network traffic for malicious or anomalous activity and takes automated actions to block or mitigate it. An IPS can also alert the system administrators of any potential threats and provide detailed logs and reports of the incidents. An IPS can help the company to improve its security posture and prevent data breaches, unauthorized access, or denial-of-service attacks. References:

Credential stuffing is a type of attack that involves using stolen or leaked usernames and passwords from one website or service to gain unauthorized access to other websites or services that use the same credentials. It can exploit the common practice of reusing passwords across multiple accounts. It is the most likely attack that has been used to compromise the manager’s corporate account, given that the manager is using the same password across multiple external websites and the corporate account, and one of the websites recently experienced a data breach.

CIS benchmarks are best practices and standards for securing various operating systems, applications, cloud environments, etc. They are developed by a community of experts and updated regularly to reflect the latest threats and vulnerabilities. They can be used to update and reconfigure the OS-level security configurations to ensure compliance and reduce risks

Jamming is a type of denial-of-service attack that involves interfering with or blocking the wireless signal using a device that emits radio waves at the same frequency as the wireless network. It can cause the wireless network to be down and users to be unable to connect to it, especially if they are working in a building near the parking lot where someone could easily place a jamming device.

Honey pots are decoy systems or resources that are designed to attract and deceive threat actors and to learn more about their motives, techniques, etc. They can be deployed alongside production systems to create an illusion of a vulnerable target and divert attacks away from the real systems. They can also collect valuable information and evidence about the attackers and their activities for further analysis or prosecution. 

Containment is an incident response strategy that aims to isolate and prevent the spread of an attack or compromise within a network or system. It can resolve the issue of unauthorized software detected on a small number of machines in a lab as quickly as possible while causing minimal disruption to the researchers by stopping the software from communicating with external sources using HTTPS and SMS and preventing it from infecting additional machines outside of the lab

Wireshark is a tool that can analyze pcap files, which are files that capture network traffic. Wireshark can display the packets, protocols, and other details of the network traffic in a graphical user interface. Nmap is a tool that can scan networks and hosts for open ports and services. CURL is a tool that can transfer data from or to a server using various protocols. Neat is a tool that can test network performance and quality.

MFA (Multi-Factor Authentication) is a method of verifying a user’s identity by requiring two or more factors or attributes that belong to different categories. The categories are something you know (such as a password or a PIN), something you have (such as a token or a smart card), something you are (such as a fingerprint or an iris scan), something you do (such as a gesture or a voice command), and somewhere you are (such as a location or an IP address). In this case, the user enters a password (something you know) and then receives an authentication code (something you have) to log in to a workstation.

A full inventory of all hardware and software would help ensure a security analyst is able to accurately measure the overall risk to an organization when a new vulnerability is disclosed, as it would allow the analyst to identify which systems and applications are affected by the vulnerability and prioritize the remediation efforts accordingly. A full inventory would also help the analyst to determine the impact and likelihood of a successful exploit, as well as the potential loss of confidentiality, integrity and availability of the data and services.

A deterrent control is a type of security control that is designed to discourage potential intruders from attempting to access or harm a system or network. A deterrent control relies on the perception or fear of negative consequences rather than the actual enforcement of those consequences. A deterrent control can also be used to influence the behavior of authorized users by reminding them of their obligations and responsibilities. An example of a deterrent control is placing fake cameras around the building, as it can create the illusion of surveillance and deter potential intruders from trying to break in. Other examples of deterrent controls are warning signs, security guards, or audit trails. References:

A corrective control is a type of security control that is designed to mitigate the damage caused by a security incident or to restore the normal operations after an incident. A corrective control can include actions such as restoring from backups, applying patches, isolating infected systems, or implementing new policies and procedures. A corrective control is different from a preventive control, which aims to stop an incident from happening, or a detective control, which aims to identify and record an incident. References:

A network DLP (Data Loss Prevention) solution is a tool that monitors and controls the data that is transmitted over a network. It can inspect in-transit files on the enterprise network to search for PII (Personally Identifiable Information), credit card data, and classification words by using predefined rules and policies, and then block, encrypt, quarantine, or alert on any sensitive data that is detected or leaked. 

SPIM (Spam over Internet Messaging) is a type of VoIP-associated vulnerability that involves sending unsolicited or fraudulent messages over an internet messaging service, such as Skype or WhatsApp. It can trick users into clicking on malicious links, downloading malware, providing personal or financial information, etc., by impersonating a legitimate entity or creating a sense of urgency or curiosity. Vishing (Voice Phishing) is a type of VoIP-associated vulnerability that involves making unsolicited or fraudulent phone calls over an internet telephony service, such as Google Voice or Vonage. It can trick users into disclosing personal or financial information, following malicious instructions, transferring money, etc., by using voice spoofing, caller ID spoofing, or interactive voice response systems. 

TLS (Transport Layer Security) is a cryptographic protocol that provides secure communication over the internet. It can protect the data transmitted between the website and the visitors from eavesdropping, tampering, etc. It is the most secure protocol to implement for a website that sells products online using a credit card.

WAF stands for Web Application Firewall, which is a type of firewall that can monitor, filter and block web traffic to and from web applications. WAF can protect web applications from common attacks such as cross-site scripting (XSS), SQL injection, directory traversal, buffer overflow and more. WAF can also enforce security policies and rules that can prevent parameter manipulation or tampering by an unknown third party. WAF is the best solution to help protect against the attack on the web API, as it can inspect the HTTP requests and responses and block any malicious or anomalous activity. Verified References:
