6. Violations of security policies. At times, users will make illegal attempt to penetrate the network without clearance and permission. Internal users must understand what happens when someone violates the policy in attempt to protect internal IT systems on the intranet.
7. Malicious content. Intranet users are vulnerable to malicious content (viruses, worms, and Trojan Horses) that attach themselves on emails. Businesses and users alike must remember to always maintain and update their security software on every PC and server on an intranet to ensure protection.
8. Usability problems. There are users who still improperly use the intranet. They do not know how to search, retrieve, send or share data and information; often, doing more harm than good on the private network. Some users may need formal training.
9. Weak passwords. Users tend to use weak passwords, write down passwords, never change them, or forget them. Network administrators must encourage users to overcome these issues and have them use hard-to-guess passwords, as well as not to share them, or write them down.
10. Lack of encryption. Many times unsecured "confidential" data is shown to unauthorized users because they do not use encryption. Using SSL digital certificates can help secure the Intranet.
Intranet Tip: Set up firewall rules to allow only those messages that originate from the internal server.
Advice: Any person granted access to an intranet should receive formal security training first. Users need an IT security policy handy to know what to do when there is a security violation, a security threat or attack, or learn how to resolve all other intranet security issues such as those mentioned above.
Solution: Businesses can set up on their own intranet and choose a software solution like Office Ability to overcome some of the common security issues like usability problems, passwords, and encryption, or use HyperOffice, which is a business that offers their own "Securely Hosted Intranet Software Solution" for other businesses.
