Hack

The first big-name hackers include Steve Wozniak,Bill Gates and Linus Torvalds,all now highly recog-
nizable names behind many of the computer technologies used today. These early hackers had a love of tech-
nology and a compelling need to know how it all worked,and their goal was to push programs beyond what
they were designed to do.Back then,the word"hacker" didn't have the negative connotation it has today.
The original hacker ethic,rooted out of simple curiosity and a need to be challenged,appears to be dead.
The objectives of early hackers are a far cry from the goals of today'S hacker. The motivation of the new
breed of hackers appears not to be curiosity,or a hunger for knowledge,as it used to be.Instead,most of to-
day'S hackers are driven by greed,power,revenge,or some other malicious intent,treating hacking as a game
or sport,employing the tools that are retdily available via the Internet.
The rate of security attacks is actually outpacing the growth of the Internet.This means that something
besides the growth of the Internet is driving the rise in security attacks.Here are some realities you should
know about:Operating systems and applications will never be secure.New vulnerabilities will be introduced
into your environment every day.And even if you ever do get one operating system secure,there will be new
operating systems with new vulnerabilities一phones,wireless devices,and network appliances.Employees will
never keep up with security polices and awareness.It doesn't matter how much you train and educate your
employees.If your employees disregard warnings about the hazards of opening questionable e-mail attach-
ments,how are you going to educate them about properly configuring firewalls and intrusion detection systems
for their PCs?Managers have more responsibility than ever. And on top of the realities listed above,security
managers are being asked to support increasing degrees of network availability and access.There are some
good security measures you can take:Employ a layer 7,full-inspection firewall.Automatically update your
anti-virus at the gateway,server and client. Keep all of your systems and applications updated.Hackers com-
monly break into a website through known security holes,so make sure your servers and applications are
patched and up to date.Turn off unnecessary network services.Eliminate all unneeded programs.Scan net-
work for common backdoor services一use intrusion detection systems,vulnerability scans,anti-virus protection. Various security measures are recommended EXCEPT_________.
A.turning off network services
B.employing a full-inspection firewall
C.making sure that servers and applications are patched
D.eliminating all unneeded programs
