They are viruses, Spyware, Trojan and worms. Virus is a self infection by copying other normal file malware, infected files can be utilized to remove the virus after return to normal, there are some infected files cannot be cleared. At this time recommended to delete the file, reinstall the application. According to the author Kirby explains spyware - just like a spy, a hacker uses spyware to track internet activities and steal people’s information and also install backdoors in user computers without people being conscious of it (Kirby, 2015). The user's private data and important information will be the backdoor acquisition; even these "backdoor" can allow hackers to remotely manipulate the user's computer.
You still believe that you are talking to the original party and may send private information to the hacker by accident. (d) Sniffer attacks A sniffer is an application that can read, monitor or capture network data exchanges and read network packets. If the packets are not encrypted, a sniffer provides a full view of the data inside the packet. Even encapsulated packets can be broken open and read unless they are encrypted and the attacker does not have access to the key. (e) Password attacks Password based attacks or password crackers are aimed at guessing the password for a system until the correct password is determined.
CS 507 (Assignment No 2) Part I (PHISHING) 1. Phishing. Phishing is an attempt to acquire sensitive information such as usernames, passwords and credit card details for malicious reason by masquerading as a trustworthy entity in an electronic communication. 2. How it Affect / Attack.
There are various examples of network attacks, the following is a list of a few of the most common: Eavesdropping (sniffing/snooping) – It the use of exploits to gain access to the data path of a communication and interpret the traffic therein, basically giving them ability to monitor the data passing through. Data modification – Altering the data within a packet without the sender/receiver aware of the change. IP address spoofing – Otherwise known as identity spoofing, is the use of special programs to change the originating address of an IP packet and therefore allowing them to falsify the source of the data itself. Password-based attacks – Is the use of common passwords and “brute force” to allow an intruder to masquerade themselves as the user and gain access to the users account. Denial-of-service attack (DOS attack) – It is the use of a variety of methods to prevent a valid/authorized user from the using a computer system or network.
Government surveillance can have adverse effects on anyone’s life as it can be used to harm an individual’s reputation by exposing their personal information. In the digital age, terrorist’s use of the internet has increased to such an extent that all their communication and daily transactions occur on the internet. Keeping a close watch of the internet is almost necessary to prevent an unforeseen circumstance and to limit the approach of terrorist organizations around the world. The internet serves as the main source for recruits, funding and information, so limiting their access to the internet can prove effective in countering terrorists. The purpose of this paper is to investigate the question if government surveillance is necessary to counter terrorism.
One example is spyware which collects information about how a user uses a software application and reports that information back to the software vendor. If the vendor does not alert the user to the fact that the software application does this, then it is spyware. Other spyware is annoying. Adware monitors a user's Internet use and occasionally displays pop-up advertisements while the user is browsing the Internet (the intent is to make the user believe that the pop-up messages are being produced by the web pages they are browsing, so that they do not realize they have adware on their computer). Many forms of spyware, however, are more malicious and can have serious effects on users and businesses.
Security is like a strong protective wall which blocks the bad guys and launching small, well-guarded doors to provide secure. So, this will prevent unauthorized organization to leak into or attack company system. E-commerce is an online transaction between buyers and sellers through the internet via devices such as computers or mobile phone. Nowadays, hacker can easily get valuable information from innocent victims. The most common security threat is stealing information of credit card and location details.
In this paper it achieves effective analysis of communication traffic and detects the type of attack, its occurrence into the communication system. But the paper not proposed the optimal combination of different classification techniques and different Intrusion Detection System (IDS) for achieving a higher overall accuracy for intrusion detection. Thus, the scheme is subjected
This accessibility could result in planting a virus , accessing sensitive files, or by impeding network performance by flooding network with illegitimate packets. Unauthorised access can be prevented through network firewalls which may be hardware devices, software programs, or a combination of the two Improves Stakeholder Confidence One of the benefits of cyber security is that it improves the reputation of an organization By giving careful consideration to cyber security an organization is able reassure its stakeholders that it is well-prepared to encounter any cyber risks . It indicates to its customers that it cares about protecting their
