Man in the middle attacks - People extracting sensitive and confidential information whilst posing to be a customer, or a legitimate company. Implanting Key loggers - Applications designed to record key strokes and send them back to the hacker. External threats are this such as; Viruses - Rouge applications designed to damage or make a system vunerable Trojans - Applications designed to infiltrate a system often by posing to be a harmless file or embedded into another file. Piggybacking - A term given to people who use someone else's internet connection without authorisation. This is often undertaken by logging onto an unsecured network without permission. Phishing - Attempting to fool a user into believing you are a legitimate service attempting to gain sensitive information. * Damage to or destruction of systems or information Damage to systems can occur when devices fail such as hard drives failing or natural disasters occurring in the workplace that could result in damaged or destroyed places.

Counterfeit goods are becoming increasingly popular as the ease of ripping DVD's, Music and Software makes it easier to access. Counterfeit goods may cause loss of business for companies.

Conclusion

And also as a countermeasure to attempt to catch anyone with malicious intent. Countermeasures Vermason could implement to protect network security - p4: Backups - Backups are an essential countermeasure in offices. If there was an electrical fire or other natural disaster that could result in loss of data, this would insure that all essential data such as databases the company requires to undertake work related tasks are still there aswell as contact, supplier and customer information so that they do not need to be re-acquired. Passwords - Passworded systems can be implemented to secure individual workers within the company, it firstly provides an element of data security for each individual (eg; sensitive information that may be kept on a user account) and also holds each user responsible for there own actions on the computer under there own user account. More importantly; passwords ensure that only legitimate employees have access to important company files and other such potentially confidential information. Firewalls - A firewall would prevent unauthorised access from outside the network. It does this by scanning data packets coming onto the computer and ensuring that they are safe, it also is responsible for actively preventing virus's such as Trojans being downloaded from the internet and onto the network computers. Installing a firewall would prevent hackers from accessing the network and stealing data or causing damage. ?? ?? ?? ?? Chris Leversha - Page | 1 - 07/10/2010 ...read more.
