hacker attacks on websites went up 75% in the final quarter of 2013, with
hackers in China responsible for 43% of all attacks.
• eBay went down in a blaze of embarrassment as it suffered this year’s

7. Computer Security - Threats
• Denial-of-Service (DOS)
– Prevention of legitimate access to systems
– Different types:

• Teardrop-attack that involves sending fragmented
packets to a target machine.
• Smurf-attack in which large numbers of Internet
Control Message Protocol (ICMP) packets with the
intended victim's spoofed source IP are broadcast to a
computer network using an IP Broadcast address.

Firewall: Barrier between network and
the outside world.
Proxy server: Sits between users
and server. Two main functions
are to improve performance and
filter requests.

11. Cyber Targets
• 99% of the attacks can be
prevented by basic hygiene.
DO
 Think before you click
 Up-to-date anti-virus, firewall and
site advisor
BUT
 Some new attacks may get through.
However, attacker may only use your
machine to attack others and not
attack you per se.
 Will not prevent data loss by
merchants and other servers.
• 1% of the attacks are difficult
and expensive to defend or
detect.
For most individuals
 We are simply not an attractive
enough target.
For the Defense & other sensitive govt.
departments and its contractor.
 A huge target.
 For companies in sensitive businesses
a serious threat to be taken seriously

Cyber security is a
young and immature
field.
Attack back is illegal.
The attackers are
more innovative than
defenders.
Defenders are
mired in FUD (fear,
uncertainty and
doubt)
Cyber security will
become:
•a scientific discipline
•application and
technology centric
Attack back will be a
integral part of cyber
security
