~3-page information security policy template on the use of social media.
 
This policy places reasonable constraints on what workers may and may not disclose, publish or discuss through social media, and specifies other information security controls relevant to the use of social networking websites, apps, blogs etc. 
 
Social media present both opportunities and risks to the business: there are confidentiality, integrity and availability aspects to this.  The policy strikes a reasonable balance, allowing management discretion for flexibility.
