Rootkit attacks are a serious threat to computer systems. Packaged with other malwares such as worms, viruses and spyware, rootkits pose a more potent threat than ever before by allowing malware to evade detection. In the absence of appropriate tools to counter such attacks, compromised machines stay undetected for extended periods of time. Leveraging virtual machine technology, we propose a solution for real-time automated detection and containment of rootkit attacks. We have developed a prototype using VMware Workstation to illustrate the solution. Our analysis and experimental results indicate that this approach can very successfully detect and contain the effects of a large percentage of rootkits found for Linux today. We also demonstrate with an example, how this approach is particularly effective against malwares that use rootkits to hide.

-        Suggest your security plan to avoid the virus attack in computer.

Ø   creating a strong computer password may be the easiest thing to do to improve the security of your system. Users need to provide complex passwords, which use special characters such as "# @! * &" As well as letters and numbers. Strong passwords should also be between 8-15 characters. Passwords cannot be written and stored near or under your device. Updating your computer password regularly will help prevent crack password cracking. The stronger the user password, the harder it is for hackers to break it. Generally, it is a good practice to update your password every 90 days.

Ø  Installing anti-virus software is installing anti-virus software is a very important step to ensure that the computer network remains protected from viruses. Anti-virus software actively scans viruses that attempt to infiltrate email, system files, and / or operating systems

Ø  Regularly update computer system is It is very important to run regular computer system updates. Companies like Microsoft provide periodic updates to their software to repair any bugs and abnormalities with the system. If you don’t allow system updates, the abnormalities and bugs that remain in system can be exploited by hackers. Make sure allow updates as they are released.

1.      I choose rootkit virus case because this case always happen nowaday. Rootkit is a collection tools(program) that enable administrator-level access to computer or computer network. Typically, a cracker install a rootkit on a computer after first obtaining user level access either by exploiting known vulnerability or cracking a password. Once the rootkit was installed, it allowed the attacker to mask intrusion and gain root or privileged access to the computer and possibly other machines on the network.

2.      Effect of security breach is revenue loss, significant revenue loss as a result of a security breach is common, studies show that 29% of businesses that face the data breach end up losing data revenue. After that damage to brand reputation, it can impact much more than a short term revenue. Next is loss of intellectual property, loss of revenue and damaged reputation can be catastrophic, in some case hackers will also target design, strategies and blueprints.

-        This case is about ransomware that happen at The Government of Nunavut. Nunavut Premier Joe Savikataaq said the government’ IT system had been hacked by a “virus” that had “targeted public services”. The Government of Nunavut identified the incident as a ransomware attack. In an update on Sunday, the government said the ransomware encrypted “individual files” on various servers and workstations. Jimi Onalik, Nunavut’s director of planning and communications, said the government was “actively addressing the computer network issue” and was “working with IT security companies and internet and software providers”.

- Justify and elaborate your answer why choose the case study.

I chose this ransomware because this incident often happens everywhere. Ransomware is one of the biggest security problems on the internet and one of the biggest forms of cybercrime that organizations face today. Ransomware is a form of malicious software that encrypts files and documents on anything from a single PC all the way up to an entire network, including servers.

1.  The effect of security breaches on hardware, software, data and people.

-        The ransomware encrypted “individual files” on various servers and workstations.

-        As a result, all government services requiring access to electronic information stored on the GN network are impacted

-         Government services loss of personal information or privacy breaches.”

-        ransomware is a malicious software which infects a computer and denies access to the system or data, and demands a sum of money to restore the information

3. Suggest your security plan to avoid the virus attack in computer.

-        Avoid clicking links in spam emails or on unfamiliar websites. Downloads that start when click on malicious links is one way that computer could get infected.

-        Do not open email attachments from senders that do not trust. Look at who the email is from and confirm that the email address is correct. Be sure to assess whether an attachment looks genuine before opening it. If not sure, contact the person that you think has sent it and double check.

-        To reduce the risk of downloading ransomware, do not download software or media files from unknown websites.

-        Avoid giving out personal data, If receive a call, text, or email from an untrusted source that asks for personal information, do not give it out.

Their latest victim was a nurse who worked in a government hospital and was offered the package by an agent on 13 September“The victim read the offer through a WhatsApp group about accommodation promotions including breakfast at a famous hotel in Port Dickson which had a package price of RM88 to RM499 a night. She contacted the company’s representative who convinced her to become an agent by offering a 10% commission so she could distribute the package to her colleagues too.

Explain the effect of security breaches on hardware, software, data and people.

As we can see, after they scamming a lots of people there must be an effect of security breaches on hardware, software, data and people. The effect to hardware is, the devices been harm because of the scammer. For software, system software cant runs the computer system software and jammed. For data, all data will be lost included such as personal information and important documentation. Lastly, for people, if in business, they must compensated people because of their low quality in security system. For personal, will face personal losses maybe a big amount of money of important document.

Suggest your security plan to avoid the virus attack in computer.

In this era of technology, Cellphones, Laptop and Computers are commonly used in daily life such as entertainment, Sells and business sectors. It is normal that the Internet would be the bridge of gathering, savings data, documents and information. Unfortunately, Internet also would bring viruses and spread through the internet and email, causing potential harm to a computer’s data, files and hard drive.

Viruses are commonly disguised as hyperlinks, pop-ups or email attachments of images, greeting cards or audio or video files.The most thing that would be aware about the various virus whether it is ‘system error’ or ‘human error’ to the gadgets easily without any awareness of security and protection of your computer data.

In my opinion, There are several strategy to avoid the virus attack in computer. The common way of the prevention strategy are by installing Anti-virus program provided. Anti-virus program could detect and prevent the spread of the virus that exposed while you still not notice, Users also should run a full virus scan every week to detect any threats. This strategy are most used by the user of Computers.

Next are by carefully surfing the internet network, It is because the viruses are most exposed in the network and could be the whole site. As a users, We should be more aware while surfing various of pages or sites in the internet. Avoid the suspicious looking sites or unofficial pages in the internet. It is because might be created by hackers for them to use and easily hacked various of users that fell into their trap.

In the nuthsell, as a user, We should be more proactive while using our gadgets. It is very important to stay alert and to increase our awareness of this viruses. The viruses might infect the information or important data in your computer files. As a result, you might lost your data and files in your computer due to the effect of the exposed viruses in the internet.
