...However, this authentication method is problematic if the two factors are compromised; the attacker can successfully obtain the password and any user data stored in the smart card. Three-factor authentication can help avoid this problem and enhance system security. Owing to the singularity, biometric authentication protocol is ideal for user authentication, and addresses the weakness of password and smart card methods. The users can use their own biometric characteristics, such as fingerprint [3], voiceprint and iris scan. Biometric characteristic identification systems offer reliable authentication because biometric characteristics cannot be copied, stolen or easily lost. Although there are many advantages in using biometrics, this approach still has some shortcomings. For example, biometric characteristics cannot be easily changed or replaced. For these reasons, there is a demand for a more secure protocol like three-factor authentication. The three-factor authentication method in this paper uses a username, password and unique id of device for device authentication/verification. The authentication is based on the characteristics of all three factors. Without device authentication (unique id of device) user can not encrypt the file or decrypt the file. The advantages of this three factor protocol are device authentication that is not applied in previous three-factor protocol. By using device authentication the system become most secure compared to previous protocols. 1.0.1 Encryption...

The XSS Validator Bookmarklet can be downloaded to check for any XSS payload that has the potential of web attack such as script or javascript and gives a warning to let user know if the URL is safe. It is also able to remove script tags, and filter payloads to direct user to the target URL. It will be able to reduce the risk of having attackers bypass access controls, send malicious content or compromise private and sensitive data from the user. Validator Bookmarklets can also be further developed to further improve protection and security. 4.1.2 Avoid Untrusted URL Sources Risks can be reduced if users are more aware of the danger of potential suspicious sources of URLs. Doing research using search engines such as Google.com, Yahoo.com, or Bing.com do not have any filter, so searching for information can result in any kind of related outcome. Anyone could post a website or file on the web and if attackers imitate a legitimate website that has high search frequency, they can lure unknowing users to their website and the users will be prone to attacks. Unnecessary risks can be prevented and avoided if users keep to familiar websites and keep researching on the web to a minimum unless absolutely required. 4.1.3 Hardening Browser Hardening the web browser can decrease the chances of attacks.

...Abstract—One main advantage of open-source technologies such as Linux is the increased security. In this paper we will discuss the type of attacks on operating system Linux Kernel such as side channel vulnerability, introduced in a recent TCP specification (RFC 5961) fully implemented in Linux kernel version 3.6, how it is spreads and what are its impact. This vulnerability allows a blind off-path attacker to infer to any two hosts on the Internet that are communicating using a TCP connection. Such an off-path attacker can also infer the TCP sequence numbers in use, from both sides of the connection; allowing to cause connection termination and perform data injection attacks. The proposed elimination methodology to the cause of the problem are also discussed. Keywords: Operting system: security attacks; denial of service;...

...Name: MUTAIB HAIL ALSAHLI ID: 120004631 Answer, Question number 1, Before we talk about the differences there are Some people who may easily forget the fact that the USB Type-C and USB 3.1 are different from each other, considering the fact that both cross platforms were developed by the USB Forum (USB-IF) simultaneously, USB Type-C is a physical connector and USB 3.1 is a technology standard. Compatible devices can transfer data at a very high speed of up to 10GB per second.USB 3.1 standard allows for high-speed data transfer, but other devices such as tablets and smartphones might not transfer data that fast's Type-C and USB 3.1 are often confused with each other. The main difference between the two is that USB Type-C is developed to support USB 3.1 signals. Some devices might have Type-C connectors which only support the older USB standards such as USB 2.0 and USB 3.0. With more and more devices such as the new Lumia, Nexus are getting equipped with USB Type-C connectors combined with USB 3.1 support, the latest smartphones' batteries are sure to charge even faster. Some limitation of USB type-c is that the new connector also has a disadvantage for example the people who have devices with USB Type-C ports cannot insert USB Type-A and USB Type-B cables in the plug without a compatible adaptor.
