The Slowloris attack is a type of application-layer attack that targets the web server by establishing and maintaining many simultaneous HTTP connections to the target server. Unlike traditional network-layer DoS/DDoS attacks such as UDP flood or SYN flood, Slowloris is designed to hold as many connections to the target web server open for as long as possible. It does so by sending partial requests, which are never completed, and periodically sending subsequent HTTP headers to keep the connections open. This consumes the server's resources, leading to denial of service as legitimate users cannot establish connections. The Slowloris attack is effective even against servers with a high bandwidth because it targets the server's connection pool, not its network bandwidth.

The technique described, where an attacker applies a magnetic field to a digital media device to clean it of any previously stored data, is known as disk degaussing. Degaussing is a method used to erase a disk or tape by exposing it to a strong magnetic field, destroying the magnetic data storage mechanism and leaving the device clean of any data. This process is effectively used for wiping digital evidence in a way that makes recovery impossible, serving as a method of anti-forensics. Unlike file wiping utilities or disk cleaning utilities, which overwrite or delete data (potentially leaving traces that can be recovered), degaussing physically alters the storage medium itself, making data recovery unfeasible.

User Behavior Analytics (UBA) is a cybersecurity process or tool that utilizes machine learning, algorithms, and statistical analyses to detect potentially harmful activities within an organization's network by comparing them against established patterns of users' behavior. It is particularly effective in identifying malicious internal actors or compromised users who may be conducting activities that deviate from their normal behavior patterns, such as accessing unauthorized data or systems, excessive file downloads, or unusual login times. UBA tools can flag these activities for further investigation, often before traditional security tools detect a breach. In contrast, SOC2 compliance reports, log forwarding, and syslog configuration are important for maintaining and auditing security standards and for infrastructure monitoring, but they are not primarily focused on detecting malicious behavior based on deviations from established user behavior patterns.

Viruses are a type of malicious software program designed to infect legitimate software programs. Once a virus is executed, it can corrupt or delete data on a computer, replicate itself, and spread to other files and systems. Unlike worms, which can spread across networks on their own, viruses usually require some form of user interaction, such as opening an infected email attachment or downloading and executing a malicious file, to propagate. Trojans and spyware, while also malicious software, serve different malicious purposes, such as creating backdoors for attackers (Trojans) or spying on users' activities (Spyware).

One of the key approaches to mitigating insider threats is ensuring that access control policies are strictly implemented and monitored. This includes the guideline that access granted to users should be thoroughly documented and vetted by a supervisor. This control helps ensure that users have only the access necessary to perform their job functions, reducing the risk of inappropriate access or misuse of information. Proper documentation and supervisor approval also ensure accountability and traceability of access decisions, which is crucial for detecting and responding to insider threats. The human resources department plays a vital role in this process, working closely with IT and security teams to enforce access control policies, conduct regular reviews of access rights, and manage the onboarding and offboarding process to ensure that access rights are appropriately updated.

The regular expression/exec(\s|\+)+(s|x)p\w+/ixis designed to match patterns that resemble SQL injection attempts, specifically targeting MS SQL Server. This expression looks for the use of theexeccommand followed by one or more spaces or plus signs, and then patterns that start withsporxp, which are prefixes commonly used in SQL Server stored procedures and extended stored procedures. These are often targeted in SQL injection attacks to execute malicious SQL statements. The regular expression provided is a tool used by incident responders like Tibson to identify and analyze potential SQL injection attempts by looking for suspicious patterns in SQL queries.

The statement "Do not download or execute applications from trusted sources" is incorrect and not considered a good practice for maintaining information security and eradicating malware incidents. In contrast, downloading or executing applications from trusted sources is a fundamental security best practice. Trusted sources are vetted and are generally considered safe for downloading software, updates, and applications. This practice helps to minimize the risk of introducing malware into the organizational environment. The other options (A, B, C) represent good practices that help in reducing the likelihood of malware infections by avoiding potentially harmful actions.

In the context of using Wireshark, a popular network protocol analyzer, to detect ping sweep attempts on a network, the filtericmp.type==8is used. ICMP (Internet Control Message Protocol) is utilized for sending error messages and operational information indicating, for example, that a requested service is not available or that a host or router could not be reached. ICMP type 8 messages are echo requests, which are used by the ping command to test the reachability of a host on an IP network. A ping sweep consists of ICMP echo requests sent to multiple hosts to find which ones are alive. By applying theicmp.type==8filter in Wireshark, Bran can isolate and examine the echo request messages, helping to identify ping sweep attempts, which are characterized by a high volume of ICMP echo requests over a broad range of IP addresses in a short period.

The term "broken account management" refers to vulnerabilities in the account management functions of web applications, which can weaken valid authentication schemes. This can include issues with how accounts are created, updated, managed, and deleted, as well as how users recover forgotten passwords or perform password resets. Poorly implemented account management functions can allow attackers to bypass authentication, elevate privileges, or assume the identity of another user. This weakness is a significant security concern because it directly impacts the ability of a system to safeguard user data and maintain operational integrity.
