The Effect on the University

• Legal Requirements

(Data Protection Act 1998)

• Reputation

• “Bad Headlines”

(An organisation like Newcastle University would make a national story)

How is Information Lost?

McAfee Survey Results 2007McAfee Survey Results 2007

•Only 23% malicious (65% of this, an inside job!)

•Only 8% of total loss due to Hacking, Phishing etc

•77% an ‘accident’ or ‘only doing my job?’

Worst Culprits?

•Malicious Act

•Accidents

•‘Doing my Job’

•Not informed of regulations

•Sharing passwords

•Publishing personal e-mails

Staff Guidance

• Communication at start of employment.• Communication at end of employment.• Think before you disclose personal

details.• Ask if you are not sure.

Passwords!Treat you passwords like a pair of knickers:

•Have different ones for different purposes.

•Make them a BIG as possible

•Change them often

•Never lend them to your friends

E-Mail

• Phishing the easiest way to get information.

• You haven’t won a laptop!• You won’t get a share in $32 Billion!• You haven’t won the Dutch Lottery!• You didn’t place that order!• Your username and password will

never be asked for in an e-mail, no matter who it says it is from!

Worst Culprits?

•Lost

•Infected Easily

•Used as ‘Backup’

•Lent to others

•Data Corruptions more common

Worst Culprits?

•Stolen

•Left at airports, on trains etc

•Hard disk corruption common

•Connected to many networks

What can we do about it?

• Laptops and Memory sticks should never have a unique copy of important information.

• All confidential information should be encrypted.

• Staff informed of good working practises.

• Make Sure Laptops are ‘Patched’ (windows update)

Hot from the Press!!!!
