Performance testing in software testing

by

It is  a type of non-functional testing. Performance testing is testing that is performed, to determine how fast some aspect of a system performs under a particular workload. It can serve different purposes like it can demonstrate that the system meets performance criteria. It can compare two systems to find which performs better. Or it … Read more

Importance of Review Process

by

Productivity of Dev team is improved and timescales reduced because the correction of defects in early stages and work-products will help to ensure that those work-products are clear and unambiguous. Testing costs and time is reduced as there is enough time spent during the initial phase. Reduction in costs because fewer defects in the final … Read more

Assessing Vulnerabilities

by

After    finding    potential    security    holes,    the    next    step    is    to    confirm    whether    they’re indeed    vulnerabilities    in    the    context    of    your    environment.    Before    you    test,    perform some    manual    searching.    You    can    research    websites    and    vulnerability    databases,    such    as these: Common    Vulnerabilities    and    Exposures    ( http://cve.mitre.org/cve ) US-CERT    Vulnerability    Notes    Database    ( www.kb.cert.org/vuls ) NIST    National    Vulnerability   … Read more

Securing Session Management

by

The defensive measures that web applications must take to prevent attacks on their session management mechanisms correspond to the two broad categories of vulnerability that affect those mechanisms. In order to perform session management in a secure manner, an application must generate its tokens in a robust way and must protect these tokens throughout their … Read more

Vulnerable Mapping of Tokens to Sessions

by

Various common vulnerabilities in session management mechanisms arise because of weaknesses in the way the application maps the creation and processing of session tokens to individual users’ sessions themselves. The simplest weakness is to allow multiple valid tokens to be concurrently assigned to the same user account. In virtually every application, there is no legitimate … Read more
