ICT Best Practises -Apply vendor-supplied fixes necessary to repair security vulnerabilities

It is imperative that vendor-supplied security fixes (patches) be applied to protect against system compromise. Almost all security breaches occur because of inadequately patched systems. Technicians must:

• Read through and follow security information in the knowledge base under the category SECURITY in http://answers.mak.ac.ug/category/security . 
• Subscribe to vendor and industry security alert services for technologies supported. you can also follow trends on twitter and facebook, most companies have that kind of online presence and they are always updating on the latest information.
• Apply relevant security patches promptly.
• Where patches cannot be applied because they will negatively affect critical operations, mitigating controls (either at host-level or at network-level) must be installed in order to minimize the risk caused by the particular flaw.
