CyberSecurity

• Information and Technology Security

• Virus, Spam, Intrusion Detection

• Internet Traffic Management

CyberSecurity

• Hacking– to devise or modify (a computer program), usually skilfully

– to circumvent security and break into (another's server, website, or

the like) with malicious intent

CyberSecurity

• Spam– disruptive online messages, especially commercial

messages, posted on a computer network or sent as email

– Use to initiate a ‘con’

Methods

• Exploitation – Use computer’s programs to probe for vulnerabilities and exploit them

– Often try to gain access to the computer or information on it

– Use computer as a ‘host’ for other activities

• Social engineering

– Convince you to carry out an action where you voluntarily install software

(either known or unknown)

What is Spam?

• Unsolicited email

engineering

approach when you receive strangely worded or

sensationalist emails in your inbox

not open attachments or click on links

If you think you have been spammed
