A computer system enables a business to reduce risks from phishing electronic messages. One or more original web links embedded in the electronic message may be replaced with a replacement web link. If the determined risk score for the original webpage is large enough webpage and the user clicks on the embedded web link, a user is directed to an intermediate webpage rather than to the original webpage. The intermediate webpage may provide details about the original webpage so that the user can make an informed choice whether to proceed to the original website. For example, the intermediate webpage may provide pertinent information to a user such as the actual domain of the remote site, the country the site is hosted in, how long the site has been online, and a rendered screen capture of the remote website, and/or a confidence score.

A process hazard analysis (PHA) is performed in a data processing system. A chemical process to be evaluated is selected, after which a study type to be performed on the chemical process is also selected. The study type is conducted to evaluate the chemical process for the presence of hazard scenarios and any associated deficiencies requiring recommendations. After conducting the study, resolution plans to address the recommendations are generated. The study type used in the analysis may be customized or may be a known study type. The study type may use a risk matrix to generate a risk ranking for the hazard scenario. The risk matrix used may be created by the user, or may be a known risk matrix from another study type. After a resolution plan is generated, a resolution database may also be generated.

A risk ranking tool includes a retrieval engine, a data risk engine, an operational risk engine, and a data security engine. The data risk engine calculates, using graph data, a plurality of calculated data risk scores that each indicate an amount of data risk for nodes of the graph data. The operational risk engine calculates, using the graph data, a plurality of calculated operational risk scores that each indicate an amount of operational risk for nodes of the graph data. The data security engine determines whether any of the calculated data or operational risk scores equal or exceed a predefined score, and in response, initiates a security action related to the calculated risk score that exceeds the predefined score.
