2INTRODUCTIONEthical hacking- also known as penetration testing or intrusion testing or red teaming has become a major concern for businesses and governments.Companies are worried about the possibility of being “hacked” and potential customers are worried about maintaining control of personal information.Necessity of computer security professionals to break into the systems of the organisation.
3INTRODUCTIONEthical hackers employ the same tools and techniques as the intruders.They neither damage the target systems nor steal information.The tool is not an automated hacker program rather it is an audit that both identifies the vulnerabilities of a system and provide advice on how to eliminate them.
4PLANNING THE TEST Aspects that should be focused on: Who should perform penetration testing?How often the tests have to be conducted?What are the methods of measuring and communicating the results?What if something unexpected happens during the test and brings the whole system down?What are the organization's security policies?
5The minimum security policies that an organization should posses Information policySecurity policyComputer useUser managementSystem administration proceduresIncident response proceduresConfiguration managementDesign methodologyDisaster methodologyDisaster recovery plans.
6Ethical hacking- a dynamic process Running through the penetration test once gives the current set of security issues which subject to change.Penetration testing must be continuous to ensure that system movements and newly installed applications do not introduce new vulnerabilities into the system.
7Who are ethical hackers The skills ethical hackers should possesThey must be completely trustworthy.Should have very strong programming and computer networking skills and have been in networking field for several years.
8Who are ethical hackers Should have more patience.Continuous updating of the knowledge on computer and network security is required.They should know the techniques of the criminals, how their activities might be detected and how to stop them.
9Choice of an ethical hacker An independent external agency.black box testing.An expertise with in your own organization.white box testing.
10AREAS TO BE TESTED Application servers Firewalls and security devices Network securityWireless security
11Red Team-Multilayered Assessment Various areas of securityare evaluated using amultilayered approach.Each area of security defines how the target will be assessed.An identified vulnerability at one layer may be protected at another layer minimizing the associated risk of the vulnerability.
12Information security (INFOSEC)- A revolving process
14Attacks on Websites:- Denial of service attack Some hackers hack your websites just because they can.They try to do something spectacular to exhibit their talents.Their comes the denial of service attack.During the attacks, customers were unable to reach the websites, resulting in loss of revenue and “mind share”.On January 17, 2000, a U.S. library of congress website was attacked.
17The ethical hack itself Testing itself poses some risk to the client.Criminal hacker monitoring the transmissions of ethical hacker could trap the information.Best approach is to maintain several addresses around the internet from which ethical hackers originate.Additional intrusion monitoring software can be deployed at the target.
18IBM’S Immune system for Cyber space Any of the following combination may be usedRemote network.Remote dial-up network.Local network.Stolen laptop computer.Social engineering.Physical entry.
20Competitive Intelligence A systematic and ethical program for maintaining external information that can affect your company’s plans.It is legal collection and analysis of information regarding the vulnerabilities of the business partners.The same information used to aid a company can be used to compete with the company.The way to protect the information is to be aware of how it may be used.
21Information Security Goals Improve IS awareness.Assess risk.Mitigate risk immediately.Assist in the decision making process.Conduct drills on emergency response procedures.
22ConclusionsNever underestimate the attacker or overestimate our existing posture.A company may be target not just for its information but potentially for its various transactions.To protect against an attack, understanding where the systems are vulnerable is necessary.Ethical hacking helps companies first comprehend their risk and then, manage them.
23ConclusionsAlways security professionals are one step behind the hackers and crackers.Plan for the unplanned attacks.The role of ethical hacking in security is to provide customers with awareness of how they could be attacked and why they are targeted.“Security though a pain”, is necessary.
