Incident Response Strategies

Introduction 

For many years, buffer overflow attacks have been a prevalent means of breaching Microsoft IIS web servers. When an attacker delivers more data than a given program or system can manage, the data overflows into nearby memory space, leading to this attack. The attacker can then use this overflow to carry out arbitrary code and obtain unauthorized entry into the system. Attacks involving buffer overflows on Microsoft IIS web servers have been reported to damage the server’s HTTP.sys element (Butt et al., 2022). An example is the SQL Slammer, a computer worm discovered in 2003 and capitalized on a buffer overflow fault in Microsoft’s SQL Server and Desktop Engine database systems. It is a little piece of code that does nothing more than generate random IP addresses and transmit itself to them. Suppose the specified address belongs to a host that utilizes an unpatched copy of Microsoft SQL Server Resolutions Service running on UDP port 1434. In that case, the host gets infected and starts spreading the worm program throughout the internet (Candea, 2003). Microsoft had a fix out for six months previous to the worm’s release, but numerous systems had not been patched. SQL Slammer resulted in a denial of service on some web hosts, ISPs, and ATMs and a significant slowdown in overall internet traffic. In accordance with Silicon Defence, it propagated quickly, attacking 90% of vulnerable hosts within 10 minutes. Buffer overflow happens primarily because software developers neglect to execute bounds checking; thus, programmers must pay careful attention to areas of code that employ buffers, particularly routines that interact with user-supplied data.

Incident Response Strategy

# Import necessary libraries

import requests

import struct

# Set target server and payload

target_server = “http://vulnerable_server.com/”

payload = b”A” * 8000 + struct.pack(“<L”, 0x41424344)

# Send HTTP request containing the payload to exploit the buffer overflow vulnerability

response = requests.get(target_server + payload)

# Check for successful exploitation of the vulnerability

if response.status_code == 200:

print(“Buffer overflow vulnerability successfully exploited!”)

else:

print(“Failed to exploit the buffer overflow vulnerability.”)

Incident Recovery Processes

To stop the buffer overflow attack from spreading, I must isolate any infected devices from each other, shared storage, and the network. The attack rate and quickness are crucial in combating assaults before they spread throughout the network and encrypt the data. By suspecting an infection, I will first isolate it from other computers and storage devices. Second, I will determine the type of attack. Thirdly, I will report the attack to the authorities in order to aid support and coordinate counter-attack efforts. Then I will decide which method is better for the company. Then we will plan for restoration and implement safeguards to prevent repeat occurrences (Onwubiko, 2020).

Conclusion

A buffer overflow attack can jeopardize any organization’s cybersecurity. To reduce the danger of a buffer overflow attack on a Microsoft IIS web server, businesses should verify that all servers have the most recent patches and updates and security safeguards such as firewalls and intrusion detection systems. Furthermore, firms should train their staff on the dangers of phishing emails and other social engineering assaults, as they can be a common entrance point for attackers. Regular safety inspections and vulnerability examinations can also assist in identifying and mitigating potential vulnerabilities before attackers exploit them.

Inside The Mind Of A Serial Killer: Why They Kill

“Who is a serial killer? ” when such a question pops out, most of us would answer, “They were just born like that” or “They are just loners who have no friends,” but rather, that is not the case. When doing more research, we are exposed to how ” these” serial killers have dealt with many traumas from their childhood, including sexual abuse, child abuse, child neglect, and many more reasons that result in them becoming who they are. With these reasons, we understand that these people are just like us but have different behavior, which gives us a reason to believe that serial killers are made but not born serial killers. Katherine Ramsland, who wrote “Inside the Minds of Serial Killers: Why They Kill,” tells us stories of serial killers and how they became. This book digs deep into how serial killers develop from within their situations and how being a psychopath is more likely to do with the upbringing of an individual. Moreover, we also understand the different types of serial killers (Ramsland, 2006).

In this research, Ramsland mentions that there is a variety of serial killers, from psychotic killers and murder teams to also sexual predators (Ramsland, 2006). Ramsland reflects on this in order to present the separate psychological undercurrents that differentiate serial killers from violent murderers. Moreover, the researcher addresses thrill, rage, desire for company, control, lust, profit, delusions, and the need to impress their partners among the philosopher maneuvers for serial killers (Ramsland, 2006).

Serial killers live a double life by hiding what they do to those they live with (Ramsland, 2006). The research shows how the associate describes these killers, including parents, co-workers, siblings, lovers, and survivors. Along with the research, we are convinced that serial killers have anonymous profiles with lively frightening details.

Ramsland indicates that there are plenty of cultural methodologies about serial killers that are often spread even by mental health specialists. When it comes to believing who serial killers are, we tend to think that serial killers are cleverer than the rest of us or that they often go to the same person time and again and that they are more charming and attractive. However, that is not the case (Ramsland, 2006). The research shows many or rather different types of serial killers. Even though there are plenty of different types of books that clarify the serial killer phenomenon in relation to victim type or context, none of them are yet to come up with a definition that covers the wide range of these people and their difficult mental dynamics.

In this research, we are introduced to how the act of murder simulates lust killers; these are also known as thrill killers. These are killers whose overall motives are associated with fantasies, mainly during puberty. This means they fancy anything from body parts to dead animals to underwear (Ramsland, 2006). For instance, Jerome Brudos, a man from Oregon, was attracted to women’s underwear, feet, and even shoes. This led him to steal women’s belongings in the name of lust. While he continued with this behavior, he eventually spotted an opportunity to engage his unrealities fully in murder and the corpse control that yielded a foot (Ramsland, 2006).

Overall, Katherine makes us understand that serial killers develop from within their circumstances, and for anyone to identify a serial killer, a research warranty is included, which includes their; physiology, family legacy, childhood conditions, social influences, fantasies, coping mechanisms, frustrations and strategies for continuing their murders. Even though they are not all the same, we are shown how they have developed to becoming extreme offenders and a way to protect ourselves from them and to readdress the children’s energy at the dangers of antisocial deeds. Moreover, We do not understand Inside the Minds of Serial Killers and Why They Kill.

Operations Management Plan For An Online Tutoring Service

This paper aims to formulate an operations management strategy for an internet-based tutoring platform. In recent years, there has been a notable surge in the popularity of online tutoring, which offers convenient and easily accessible educational assistance for students across various age groups. This business model integrates the benefits of technology and individualized instruction, providing various tutoring services via virtual platforms. This paper aims to examine multiple facets of the business, encompassing its target market, service delivery, product offerings, online presence, business size, and inventory storage requirements.

Business Model and Target Market

The online tutoring service’s selected business model will be business-to-consumer (B2C), wherein our organization directly caters to individual students. The target demographic for our services will encompass students across a wide range of educational levels, from elementary school to college (Doukakis). These students are actively seeking academic support in a variety of subjects. Our business offers personalized and tailored tutoring sessions that cater to individual learners’ unique needs, learning styles, and academic goals (Doukakis). This methodology guarantees that every student is provided with customized assistance and direction, thereby optimizing their educational achievements and overall contentment with our offerings.

Service Offering

The online tutoring service will provide pupils with a wide variety of individualized lessons. Each member of our tutoring staff has extensive training and expertise in their field, guaranteeing excellent instruction and guidance in the classroom. We will go over many different topics, such as math, science, English, and standardized exam practice. Because of the variety of options we provide, we are able to meet the needs of students of all ages and academic backgrounds (Doukakis). Whether kids struggle with elementary concepts or more complex material, our tutors have the knowledge and skills to help them succeed in school.

Online Presence

The online tutoring service will only be available via a web-based platform, making it easy for children and their parents to use it from any location with an internet connection. By harnessing the potential of technology, we do away with the necessity for physical presence, enabling students to participate in tutoring sessions without leaving the safety and familiarity of their own homes. By using this method, students may arrange their lessons whenever they choose and circumvent traditional geographical constraints (Doukakis; Helmold and Terry). As an added bonus, the online platform allows us to use a number of interactive tools, multimedia materials, and virtual whiteboards to improve the teaching and learning process and foster open lines of communication between instructors and their students.

Business Size:

The online tutoring service will start small to facilitate individual attention and keep the quality of service high. This was done on purpose so that our instructors and students could have meaningful one-on-one sessions, fostering a safe and encouraging space for learning. Keeping class sizes small allows us to better focus on giving each student the attention they deserve and the flexibility to meet their specific requirements. Our company is expanding as we acquire popularity and a larger customer base. One possible solution is to increase the number of skilled tutors on staff without sacrificing quality or individual attention to students. We will ensure our service’s core and the close relationship between students and tutors remains intact as we grow.

Service Delivery and Transportation:

The tutoring firm will primarily conduct online tutoring sessions through video conferencing software. Adopting virtual classrooms will allow instructors and students to communicate in real time, streamlining communication and improving the quality of education (Doukakis, Helmold, and Terry). Screen sharing and other video conferencing tools will make it easier for teachers to give lessons, work through issues, and explain concepts to their students. Since all of our advising sessions will take place digitally, we can use this innovation to do away with the requirement for physically transporting any of our items (Doukakis). Students and their families benefit from this method because they may use our services without leaving the comfort of their homes and without sacrificing the same degree of interaction and academic help they would get in a face-to-face situation.

Inventory Storage:

Since there is no stock for the online tutoring business, no space is needed for warehousing. However, the company may keep a digital library of instructional materials to improve the learning experience and provide extra assistance for pupils. Study guides, sample exams, encyclopedic resources, and innovative software tools are just some of the resources that will be available in this digital library (Doukakis; Helmold and Terry). The company will use cloud-based storage technologies to make these assets easily accessible and retrievable at any time. Secure data storage, scalability, and accessibility from any device with an internet connection are just a few of the many advantages of cloud storage. The digital materials are easily accessible 24/7, making them ideal for use in the classroom, at home, or in a review session. The cloud-based storage solutions will facilitate instructor-to-instructor cooperation and the easy exchange of course materials, creating a stimulating and resource-rich classroom setting (Doukakis). The online tutoring service may help students even more by keeping a digital library of educational resources in safe cloud storage so that they can provide their students access to useful learning materials and resources outside of their tutoring sessions, which will improve their overall learning experience and academic achievement.

In conclusion, an online tutoring service’s operations plan will center on the company’s business strategy, target market, service delivery, product offers, internet presence, size of business, and inventory storage needs. This online tutoring service can provide pupils with adaptable and individualized academic help because it uses a business-to-consumer (B2C) model and technology to deliver its services. Not needing shipping or a central warehouse for stock also helps simplify daily operations. Maintaining a commitment to providing excellent tutoring services allows the company to flourish while adapting to the changing demands of its clients.
