unit 6 summary

1. Loss of service and access – for a period of time, and to sop other attacks companies tend to take their services offline. Networks shut down after virus attacks to make sure their network is now more secure and virus free, this downtime costs a lot of money through loss of business, again not something that can be claimed off insurance.

2. Failure of security of confidential information (e.g. national security, payroll information, business strategies)- National security issues like Wikileaks are bad. A whole country’s reputation relies on this, lives, liberties and freedom of movement is restricted

3. Loss of information belonging to a third party – hacking for the benefit of another company or rival is called industrial espionage and it is a common business practice, illegal but common.

4. Loss of reputation – Sony found it very hard to recover from the hack, Banks like Allied Irish found it hard to justify to shareholders and stakeholders

5. Threat to national security – This is the worst level, the scariest level and all countries are prone to this and their reaction is of equal measure

6. Protection Measures

   • Placing computers above known flood levels
   • Back up systems in other locations

   • Logical
     • Authorisation permissions
     • Software firewalls - A firewall is a security-conscious router that sits between the Internet and your network with a single purpos
     • Anti-malware software – This is similar to anti-virus software in that it is designed to block attacks internally and externally.
