Data protection and security update LinkedIn

Data Protection and Password Security Update: LinkedIn On June 7, LinkedIn disclosed that “some LinkedIn member passwords were compromised.” Per LinkedIn disclosures on their blog http://blog.linkedin.com/2012/06/07/taking-steps-to-protect-our-members/ ”LinkedIn learned that approximately 6.5 million hashed LinkedIn passwords were posted on a hacker site. Most of the passwords on the list appear to remain hashed and hard to decode, but unfortunately a small subset of the hashed passwords was decoded and published.” They continued, “no email logins associated with the passwords have been published, nor have we received any verified reports of unauthorized access to any member’s account as a result of this event.” There are a few important lessons to pass along given the recent data protection disclosure by LinkedIn: Separate Company from Personal You or your employees may have a variety of social media accounts. It is a good data protection policy to use separate email and password combinations for personal use versus business use. Where possible, use a personal email and password combination to set up and access your Facebook, Twitter and LinkedIn accounts. Discourage employees from using their business credentials on social networks. In the event that an email and password combination is compromised, there is a lower probability that your vital systems will be hacked if your company is not associated with the data leak on a social network. Data Protection Can Lower Exposure When it comes to data protection and backup, the first thoughts are rapid recovery from lost data. These same techniques also apply to hacked data. By having daily backups of your data companies can better pinpoint what data may have been compromised during...

For this reason, some network administrators set strict IT policies that prevent thumb drives from being used on any office computer. There are plenty of secure services available for files sharing between computers (e.g. remote backup and remote control software). Ask your IT support professional about your policy for using USB drives and thumb drives and the impact they may have on your network security. Security Patches Operating System and Application Security patches are designed to keep your network secure. Your network security is as vulnerable as its’...
