We are in the age of Information Technology (IT) and amazinginnovations are developed. Management systems are now completelydigitalized and it has enabled people to continue working remotely inthe midst of a pandemic. With great innovations there are those thatseek to misuse or destroy systems for personal gain. Therefore IT &Information security is paramount both for organisation and products.To offer both an international approach for common security practicesand provide best results for IT & Information security there existsstandards and frameworks. In this thesis, the standard frameworksgeneral impact and value from both an organisational and a vendorsperspective is evaluated and assessed. To answer the research questionsof this thesis, standards and supporting theory were analysed andinterviewees with security professionals were held. Standards provideorganisational goals for developing a well-functioning and resilientsecurity. Standards also provide a common baseline between customerand vendors, minimising the need for tailoring in products’ securityrequirements. Furthermore, a certification for standards can increasethe confidence of the organisation or product, and generate a businessvalue. Whilst there are many benefits, the standards offer a structure onhow security can be built, but an organisation needs to understand anddevelop a security adapted to their organisation. In addition to setting upa security framework and implementing controls, organisation need tocreate security assurance processes to continuously review and evaluatemeasures to ascertain security posture.

Informell säkerhet är en kategori inom informationssäkerhet som innefattar människors attityder, uppfattningar och värderingar. Trots att informationssäkerhetsrevisioner utförs regelbundet mot organisationer är det oklart hur mycket informell säkerhet appliceras i dessa revisioner. Syftet med denna studie är att undersöka informell säkerhet och hur denna appliceras i informationssäkerhetsrevisioner. Undersökningen görs genom en tematisk analys av semi-strukturerade intervjuer.Resultatet av studien påvisar att det finns en bristande medvetenhet gällande informell säkerhet hos organisationer. Prioriteringarna hos organisationerna är istället den tekniska säkerheten. Studien uppmärksammar vikten av informell säkerhet och att denna inte glöms bort jämfört med de tekniska säkerhetsaspekterna.Slutsatsen i studien är att det krävs mer forskning inom området som både fokuserar på informell säkerhet i sin helhet men även hur informell säkerhet förhåller sig till organisationskultur. Det finns ett antal förbättringsområden inom området, mestadels kopplade till medvetenhet och utbildningsinsatser. Det fundamentala förbättringsområdet identifierades dock i att organisationer får en grundlig och klar insyn i vikten av väl hanterad informell säkerhet. / Informal security is a subcategory of information security that includes people's attitudes, perceptions and values. Although information security audits are regularly performed towards organizations, it is unclear how much informal security is applied in these audits. The purpose of this study is to examine informal security and how it is applied in information security audits by organizations. This is done through thematic analysis of semi-structured interviews. The results of the study show that there is a lack of awareness regarding informal security in organizations. The priorities of these organizations are instead technical security. What the study highlights is the importance of informal security and that it should be given the same amount of attention as the technical safety aspects. The study concludes that more research is needed about the subject informal security but also how informal security relates to organizational culture. There are several areas of improvement within the study, mostly linked to awareness and educational efforts. However, the fundamental area of improvement was identified as organizations realizing the importance of informal security.
