Security is a hot topic – think about last week’s WannaCrypt attack. Many businesses around the world were victims, affecting over 100,000 machines in 100 countries within 24 hours. Protecting data, whether On-Premises or via the cloud, is on every organisation’s agenda.
In March this year, Microsoft released a security update which addressed the vulnerability of such attacks. For those who have Windows Update enabled, they were fortunately protected against attacks on this vulnerability.
Attacks of this nature may evolve over time so it is essential that an organisation takes the time to ensure they are running a supported version of SharePoint. Many Microsoft customers may still be running a version of Windows that no longer receives mainstream support.
What does WannaCrypt do?
In its basic form, WannaCrypt can replicate itself and spread to other machines on your computer network, making it a hybrid ransomware programme. Infection is spread via SMB (Server Message Block) protocol which is used to communicate with other file servers across a network. The programme then encrypts most of the files on a machine and a payment demand appears on the screen. Access to files may be lost forever if the demand for payment is not met.
Crucial Tips for SharePoint Security
There is high probability that other vulnerabilities may become exposed and exploited. Make sure you take the right steps to protect your business from future attacks:
It is also important to check the knowledgebase articles (KB article) for the updates as in some instances you may not be fully patched without performing a manual SharePoint product upgrade.
Note: Microsoft also releases Cumulative Updates for SharePoint, however these are collections of hotfixes and are not recommended for production environments unless they resolve a specific issue you are experiencing and you have fully tested the update on your own testing environments.
If you are in any doubt please contact igroup and ask about our Healthcheck product and support services. The healthcheck product involves us checking your farm’s patch level and checking that your environment is in a supported state.
