Information Security Management Systems (ISMS) is a term from the business continuity industry, and it relates to the policies and procedures you put in place to manage your IT security. Specifically, it relates to the protection of your IT data, and it is a popular topic at the moment thanks to the data protection rule changes that have occurred in the EU (GDPR), and it is popular worldwide because of the increasing success of data hijackers who insert ransomware into a company's systems, lock down some data, and then charge the company to unlock the data. It seems that companies have concentrated so long on preventing attacks from hackers and system viruses, that hijackers are able to slip smaller and less damaging ransomware attacks past a company's firewall without triggering an appropriate response.
Stopping hijackers from locking down your data is important (data availability), and the increased amount of online policing has also made data confidentiality a hot topic too. Data integrity is important too, as a simple corrupt file here or there can create costly gaps in your data. Anybody who has ever lost a family photo from a hard drive because of corrupt data will know how upsetting this sort of thing is, so imagine the damage it can do if parts of your business accounts go missing, or even parts of your current working project.
Investing resources into any type of security is always a good idea. It may be smart to divert a few of your resources from online and local security and spending a little more on ISMS to help protect you against modern data loss and against ransomware. Plus, the loss of reputation and legal costs of data breaches will leave a scar on your company. There are also more obvious benefits to increased ISMS implementation such as decreasing IT systems downtime, more identifiable risks, and the potential to save money that may have been lost through security breaches and/or unregulated staff misadventure.
