Persistent issues in encryption software: A heuristic and cognitive walkthrough

The support information accompanying security software can be difficult to understand by end-users, who have little knowledge in cyber security. One mechanism for ensuring the integrity and confidentiality of information is encryption software. Unfortunately, software usability issues can hinder an end-user’s capability to properly utilise the security features effectively. To date there has been little research in investigating the usability of encryption software and proposing solutions for improving them. This research paper analysed the usability of encryption software targeting end-users. The research identified several issues that could impede the ability of a novice end-user to adequately utilise the encryption software. A set of proposed recommendations are suggested to improve encryption software which could be empirically verified through further research

Usability and security support offered through ADSL router user manuals

ADSL routers are often used as either the target or the means for cyber crime. Many ADSL router threats could be mitigated through the effective use of inbuilt security controls and firmware updates available from vendors. Unfortunately, end‐users typically lack the technical expertise to correctly configure and secure the device. Subsequently, end‐users are reliant on well documented procedures provided by vendors in their user manuals and quick start guides. This study investigates the usability and security recommendations and encouragements put forth by vendors in their user manuals. The study demonstrates that user manual usability does not conform to ideal technical publication practices. In addition, end‐users are typically not encouraged to utilise the in‐built security features and in a few instances are actually deterred from securing their ADSL router

Sellers continue to give away confidential information on second hand memory cards sold in Australia

Second hand storage devices can be treasure troves of confidential data. This study investigated the remnant data on second hand memory cards that were purchased through Australian second hand auction websites throughout 2013. Memory cards continue to increase in capacity and are used in both smart phones and tablet computers as persistent storage. During this study a total of 140 second hand memory cards were purchased throughout 2013. Each memory card had its data recovered and subsequently analysed. The results show that sellers are sending memory cards with no evidence of erasure; poor attempts to erase data; or simply asking the buyer to erase the data prior to use. The data recovered is not only of a personal nature, but also appears to originate from Australian government departments and business. It is evident that actions must be taken by second hand auction sites, and the media to raise awareness and educate end‐users on how to dispose of data in an appropriate manner
