Reaction Essay - Lab Report Example He argues that reconstructing the informants’ perceptions of the fieldworker as, variously, academic hustler, ‘nigger just like us’ and ‘Arab’ – can aid the researcher in determining patterns of structure and meaning among the individual, group, and/or community under study. He intended his article therefore to reflect on informants’ construction of his subsumption within a field of social relations in which the ‘hustle’ was an overriding organizing standard. To compare this article now with another article entitled â€Å"Personal Safety in Dangerous Places† by Terry Williams is to see first what the latter author is saying about. Williams introduced his work by saying that personal safety during fieldwork is seldom addressed directly in the literature. He narrated a fact drawn from his many prior yeas of ethnographic research and from field experience while studying crack distributors in New York City, where the authors provided a variety of strategies by which ethnographic research can be safely conducted in dangerous settings. He explained that by protecting an appropriated demeanor, ethnographers can seek others for protector and locator roles, routinely create a safety zone in the field, and establish compatible field roles with potential subjects. Terry Williams (1992) therefore intended of his article to provide strategies for avoiding or handling sexual approaches, common law crimes, fights, drive-by shootings, and contact s with the police. He found out that when integrated with other standard qualitative methods, ethnographic strategies help to ensure that no physical harm comes to the field-worker and staff members. He added that the presence of researchers may actually reduce (and not increase) potential and actual violence among crack distributors/abusers or others present in the field setting (Williams, 1992). In short what he was saying was

Network Security Paper - Essay Example This essay focuses on the increased concern over the effects of the heartbleed bug on the internet security (Codenomicon, 2014). This loophole allows stealing of secured information and data under normal settings, by the SSL/TLS encryption used to protect the Internet. The SSL/TLS covers privacy and communication security for applications found in the Internet such as the web, instant messaging (IM), email and virtual private networks (VPNs). The Heartbleed bug permits any user accessing the Internet to read the systems’ memory secured by the weaker versions of the OpenSSL applications. This jeopardizes the secret keys used to pinpoint the service providers and to encode the movement, the names and passwords of the users and the authentic content. This permits hackers to spy on data, steal information straight from the services and users and to impersonate services and users (Codenomicon, 2014). The Heartbleed bug is listed in the Common Vulnerabilities and Exposures system as CVE-2014-0160. CVE (Common Vulnerabilities and Exposures) is the Standard for Information Security Vulnerability Names preserved by MITRE. The technical name, CVE-2014-0160 is named from the line of code that the bug is contained. However, a secure version of OpenSSL was released on April 7, 2014, after the Heartbleed bug was publicly revealed. At the time close to 17% an estimated half a million of the Internets protected web servers licensed by trust authorities were alleged to be exposed to the bug. Hence, permitting the stealing of the servers digital keys used to encrypt data and gain access over users session cookies and passwords (BBC News, 2014). The loophole allows a hacker to gain access of up to 64 kilobytes of server memory. However, the hackers execute the attack repeatedly to access a substantial amount of information. Therefore, a hacker can gain access to users’ cookies from web browsers and servers that keep
